The modulated hydraulic pressure is used to prevent wheel lock up during braking. The CAB also provides a vehicle speed signal (VSS) to the powertrain control module. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 15 Electronic Brake Control Module: Description and Operation With Four Wheel Antilock Brakes CAB/HCU The Controller Antilock Brakes (CAB) is mounted on the top of the hydraulic control unit. The CAB operates the ABS system and is separate from other vehicle electrical circuits. CAB voltage source is through the ignition switch in the RUN position. The CAB contains dual microprocessors. A logic block in each microprocessor receives identical sensor signals. These signals are processed and compared simultaneously. The CAB contains a self check program that illuminates the ABS warning light when a system fault is detected. Faults are stored in a diagnostic program memory and are accessible with the DRB scan tool. ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50 times. Stored faults are not erased if the battery is disconnected. NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 16 Electronic Brake Control Module: Description and Operation With Rear Wheel Antilock Brakes RWAL Cab The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics. - Monitor the RWAL brake system for proper operation. - Control the RWAL valve solenoids. NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB. SYSTEM SELF-TEST When the ignition switch is turned-on the microprocessor RAM and ROM are tested. If an error occurs during the test, a DTC will be set into the RAM memory. However it is possible the DTC will not be stored in memory if the error has occurred in the RAM module were the DTC's are stored. Also it is possible a DTC may not be stored if the error has occurred in the ROM which signals the RAM to store the DTC. CAB INPUTS The CAB continuously monitors the speed of the differential ring gear by monitoring signals generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency when it recognizes the ring gear decelerating too rapidly. The CAB monitors the following inputs to determine when a wheel locking tendency may exists: Rear Wheel Speed Sensor - Brake Lamp Switch - Brake Warning Lamp Switch - Reset Switch - 4WD Switch (If equipped) CAB OUTPUTS The CAB controls the following outputs for antilock braking and brake warning information: RWAL Valve - ABS Warning Lamp - Brake Warning Lamp VALVE REAR WHEEL ANTILOCK BRAKES If the CAB senses that rear wheel speed deceleration is excessive, it will energize an isolation solenoid by providing battery voltage to the solenoid. This prevents a further increase of driver induced brake pressure to the rear wheels. If this initial action is not enough to prevent rear wheel lock-up, the CAB will momentarily energize a dump solenoid (the CAB energizes the dump solenoid by providing battery voltage to the solenoid). This opens the dump valve to vent a small amount of isolated rear brake pressure to an accumulator. The action of fluid moving to the accumulator reduces the isolated brake pressure at the wheel cylinders. The dump (pressure venting) cycle is limited to very short time periods (milliseconds). The CAB will pulse the dump valve until rear wheel deceleration matches the desired slip rate programmed into the CAB. The system will switch to normal braking once wheel locking tendencies are no longer present. A predetermined maximum number of consecutive dump cycles can be performed during any RWAL stop. If excessive dump cycles occur, a DTC will be set and stored in the CAB memory. If during a RWAL stop, the driver releases the brake pedal, the reset switch contacts will open. This signal to the CAB is an indication that pressure has equalized across the RWAL valve. The CAB will then reset the dump cycle counter in anticipation of the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 17 next RWAL stop. Additionally, any fluid stored in the accumulator will force its way past the dump valve, back into the hydraulic circuit and return to the master cylinder. A fuse internal to the CAB, provides a fail-safe device which prevents unwanted control over the isolation and dump solenoids. The fuse is in series with the isolation and dump solenoids output circuits. If the internal fuse is open, the CAB cannot provide voltage to energize either solenoid and RWAL stops are prevented. If the fuse is open, the braking system will operate normally but without antilock control over rear brake pressure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Service and Repair > Four Wheel Antilock Brake System Electronic Brake Control Module: Service and Repair Four Wheel Antilock Brake System NOTE: If the Controller Antilock Brakes (CAB) needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB.

The relay is an electromechanical device that switches battery current from a fuse in the Power Distribution Center (PDC) directly to the blower motor. The relay is energized when the relay coil is provided a voltage signal by the ignition switch. This arrangement reduces the amount of battery current that must flow through the ignition switch. The blower motor relay control circuit is protected by a fuse located in the junction block. when the relay is de-energized, the blower motor receives no battery current. The blower motor relay is located in the PDC in the engine compartment. Refer to the PDC label for blower motor relay identification and location. The blower motor relay cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - HVAC > Blower Motor Relay > Component Information > Locations > Page 33 Blower Motor Relay: Testing and Inspection Relay Test Blower Motor Relay The blower motor relay is located in the Power Distribution Center (PDC). Remove the blower motor relay from the PDC to perform the following tests: 1. A relay in the de-energized position should have continuity between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go to Step 2. If not OK, replace the faulty relay. 2. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to Step 3. If not OK, replace the faulty relay. 3. Connect a battery to terminals 85 and 86. There should now be continuity between terminals 30 and 87, and no continuity between terminals 87A and 30. If OK, see Relay Circuit Test in the Diagnosis and Testing. If not OK, replace the faulty relay. Relay Circuit Test 1. The relay common feed terminal cavity (30) is connected to fused battery feed directly from a fuse in the Power Distribution Center (PDC), and should be hot at all times. Check for battery voltage at the PDC cavity for relay terminal 30. If OK, go to Step 2. If not OK, repair the open circuit to the PDC fuse as required. 2. The relay normally closed terminal cavity (87A) is not used for this application. Go to Step 3. 3. The relay normally open terminal cavity (87) is connected to the blower motor. When the relay is energized, terminal 87 is connected to terminal 30 and provides full battery current to the blower motor feed circuit.

The terminal designations and functions are the same as a conventional ISO relay However, the micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay case dimensions are smaller than those of the conventional ISO relay. The compressor clutch relay is a electromechanical device that switches battery current to the compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the relay. The PCM responds to inputs from the heater-A/C mode control switch, the low pressure cycling clutch switch, and the high pressure cut-off switch. The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine compartment. Refer to the PDC label for relay identification and location. The compressor clutch relay cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - HVAC > Compressor Clutch Relay > Component Information > Description and Operation > A/C Compressor Clutch Relay Description > Page 44 Compressor Clutch Relay: Description and Operation A/C Compressor Clutch Relay-PCM Output AIR CONDITIONING (A/C) CLUTCH RELAY - PCM OUTPUT The A/C relay is located in the Power Distribution Center (PDC). The PDC is located in the engine compartment. Refer to label on PDC cover for relay location. The powertrain control module (PCM) activates the A/C compressor through the A/C clutch relay. The PCM regulates A/C compressor operation by switching the ground circuit for the A/C clutch relay on and off. When the PCM receives a request for A/C from A/C evaporator switch, it will adjust idle air control (IAC) motor position. This is done to increase idle speed. The PCM will then activate the A/C clutch through the A/C clutch relay. The PCM adjusts idle air control (IAC) stepper motor position to compensate for increased engine load from the A/C compressor. By switching the ground path for the relay on and off, the PCM is able to cycle the A/C compressor clutch. This is based on changes in engine operating conditions. If, during A/C operation, the PCM senses low idle speeds or a wide open throttle condition, it will de-energize the relay. This prevents A/C clutch engagement. The relay will remain de-energized until the idle speed increases or the wide open throttle condition exceeds 15 seconds or no longer exists. The PCM will also de-energize the relay if coolant temperature exceeds 125° C (257° F). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - HVAC > Compressor Clutch Relay > Component Information > Description and Operation > Page 45 Compressor Clutch Relay: Testing and Inspection Relay Test Compressor Clutch Relay The compressor clutch relay is located in the Power Distribution Center (PDC).

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 55 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 56 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 57 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 58 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 59 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 70 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 71 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 72 Central Timer Module ( CTM ) Low Option: Connector Views Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 73 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 74 Central Timer Module ( CTM ) Low Option: Electrical Diagrams Component Diagrams 8w-45-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 75 8w-45-3 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 76 8w-45-4 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 77 8w-45-5 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 78 8w-45-6 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 79 8w-45-7 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 80 8w-45-8 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 81 8w-45-9 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 82 8w-45-10 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 83 8w-45-11 NOTE: To view sheets referred to in these diagrams, see Complete Body and Chassis Diagrams.

The base version of the CTM is used on base models of the vehicle. The base version of the CTM combines the functions of a chime/buzzer module an intermittent wipe module and an ignition lamp time delay relay in a single unit. The high-line version of the CTM is used on high-line vehicles. The high-line CTM provides all of the functions of the base version CTM but also is used to control and integrate many of the additional electronic functions and features included on the high-line models. The high-line version of the CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity reduce internal controller hardware and reduce component sensor current loads. At the same time this system provides increased reliability enhanced diagnostics and allows the addition of many new feature capabilities. Both versions of the CTM are mounted under the passenger side end of the instrument panel outboard of the instrument panel glove box opening. For diagnosis of the base version of the CTM refer to Central Timer Module in the Diagnosis and Testing section of Chime/Buzzer Warning Systems. See: Instrument Panel, Gauges and Warning Indicators/Audible Warning Device For diagnosis of the high-line version of the CTM or the CCD data bus the use of a DRB scan tool and the proper Diagnostic Procedures manual are recommended. The CTM cannot be repaired and if faulty or damaged it must be replaced. See: Relays and Modules - Powertrain Management/Relays and Modules - Computers and Control Systems/Central Timer Module ( CTM ) High Option OPERATION Some of the functions and features that the CTM supports or controls include: ^ Chimes for the following conditions: ^ Headl amps on with ignition off and driver door open warning ^ Key in ignition with ignition off and driver door open warning ^ ABS lamp warning (if the vehicle is so equipped) ^ Airbag lamp warning ^ Check gauges lamp warning ^ Door ajar lamp warning ^ Low fuel lamp warning ^ Low washer fluid lamp warning ^ Seat belt reminder lamp warning ^ Transmission oil temperature lamp warning (automatic transmission) Courtesy lamp defeat ^ Courtesy lamp time-out (high-line only) ^ Intermittent wipe control ^ Enhanced accident response (high-line only) ^ Horn chirp upon door lock with RKE (customer programmable) (high-line only) ^ Illuminated entry (high-line only) ^ Power door lock control (high-line only) ^ Power lock inhibit (high-line only) ^ Remote Keyless Entry (RKE) (high-line only) ^ Remote radio switches (high-line only) ^ Rolling door locks (customer programmable) (high-line only) ^ Speed sensitive intermittent wipe (high-line only) ^ Vehicle Theft Security System (VTSS) (high-line only) (if the vehicle is so equipped) ^ Wipe after wash (high-line only) More information on the operation of these CTM features and functions can be found in the group that covers the system to which that feature or function applies. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Page 87 Central Timer Module ( CTM ) Low Option: Testing and Inspection For additional information on the Central Timer Module, refer to Powertrain Management / Computers and Control Systems / Body Control Module.

The horn relay is located in the Power Distribution Center (PDC) in the engine compartment. If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the PDC until further diagnosis is completed. See the fuse and relay layout label affixed to the inside surface of the PDC cover for horn relay identification and location. The horn relay is a International Standards Organization (ISO) micro-relay. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. The ISO micro-relay terminal functions are the same as a conventional ISO relay. However the ISO micro-relay terminal pattern (or footprint) is different, the current capacity is lower, and the physical dimensions are smaller than those of the conventional ISO relay. If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the PDC until further diagnosis is completed. The horn relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one movable) electrical contacts. The movable (common feed) relay contact is held against one of the fixed contacts (normally closed) by spring pressure. When the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Lighting and Horns > Horn Relay > Component Information > Locations > Page 118 Horn Relay: Testing and Inspection Horn Relay The horn relay is located in the Power Distribution Center (PDC) behind the battery on the driver side of the engine compartment.

Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System Central Timer Module ( CTM ) High Option: Description and Operation Airbag System AIRBAG SYSTEM The airbag system is designed to provide increased driver and passenger protection if the vehicle is involved in a front end collision. The system is most effective when used in conjunction with the seat belt system. The airbag control module (ACM) is an electronic module that monitors the airbag system for proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and contains the sensor and actuator that is responsible for airbag deployment. There are no external impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck at the bottom of the instrument panel. It is located forward of the console. The ACM provides diagnostic information (DTCs) to the technician through the DRB III(R) via the CCD bus.Some circuits are tested continuously; others are checked only under certain circumstances. The warning lamp is driven with messages relayed to the Mechanical Instrument Cluster (MIC) from the ACM via the CCD bus. The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be observed by the customer. Whenever the ignition key is turned to the "run" or "start" position,the airbag control module performs a lamp check by turning the AIRBAG warning lamp on for 6 - 8 seconds. If the lamp remains off, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains on, there could be an active fault in the system or the circuit that operates the lamp may be shorted to ground. If the lamp comes on and stays on for a period longer than 6-8 seconds, then goes off, there is usually an intermittent problem in the system. Perform the WARNING LAMP CIRCUIT OPEN procedure (refer to Testing and Inspection in this section) to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 136 Central Timer Module ( CTM ) High Option: Description and Operation Interior Lighting INTERIOR LIGHTING The courtesy lights are controlled by the CTM. The door switches are inputs to the CTM and the courtesy lights are outputs. The glove box lamp and the ash receiver lamp (if equipped) are not controlled by the CTM. They are hardwired to individual switches and fuses. The highline CTM also provides for illuminated entry option. If the CTM detects an unlock signal from the RKE transmitter, a door disarm switch input or the door jamb switch input, the interior courtesy lights will be turned on. The illuminated entry function is canceled if the CTM senses an ignition "on" condition or the "lock" command from a valid key fob If a door is left open or turned on by rotation of dimmer switch for more than fifteen minutes, the CTM will extinguish the lamps to avoid discharging the battery. If the lamps are turned on by courtesy lamp switch, the CTM will not be able to turn them off. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 137 Central Timer Module ( CTM ) High Option: Description and Operation Central Timer Module CENTRAL TIMER MODULE The Dakota (AN) utilizes a Central Timer Module (CTM). This system is available in a Base or Highline configuration. The Base CTM does not communicate on the CCD bus and will not be addressed. For concerns about the Base CTM, please refer to the appropriate Service Manual. The CTM performs most of the typical functions a Body Control Module would perform. The Highline CTM provides the following features: Remote Keyless Entry (RKE) - Chime - Courtesy Lamp Controls/Illuminated Entry - Power Door Locks - Speed Sensitive Intermittent Wipers - Enhanced Accident Response - Vehicle Theft Security System (VTSS) The module is located on the right side of the glove box behind a metal bracket. It contains a white 18-way and a green 14-way connector. CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODES Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure DESCRIPTION Two versions of the Central Timer Module (CTM) are available on this vehicle, a base version and a high-line version. The base version of the CTM is used on base models of the vehicle. The base version of the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, and an ignition lamp time delay relay in a single unit. The high-line version of the CTM is used on highline vehicles. The high-line CTM provides all of the functions of the base version CTM, but also is used to control and integrate many of the additional electronic functions and features included on the high-line models. The high-line version of the CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, reduce internal controller hardware, and reduce component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many new feature capabilities. One of the functions and features that both versions of the CTM support is the chime warning system. The CTM contains a chime tone generator to perform the functions of the chime warning module. The CTM uses hard-wired switch inputs, internal programming, and a hard-wired chime request input from the instrument cluster circuitry to detect when a chime tone is required. Both versions of the CTM are mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening. For diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The high-line Central Timer Module (CTM) can also control some features of the audio system when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The RAZ radio receiver with a remote radio switch option is one of the features that the CTM controls. The CTM is programmed to send switch status messages over the Chrysler Collision Detection (CCD) data bus to control the volume, seek, and pre-set station advance functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch status messages to the radio receiver. The electronic circuitry within the radio receiver responds to the switch status messages it receives by adjusting the radio settings as requested. Refer to Remote Radio Switch in the Description and Operation for more information on this component. In addition, radio receivers connected to the CCD data bus have several audio system functions that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more information on DRB testing of the audio systems. The high-line Central Timer Module (CTM) can also operate the horn system. A high-line CTM is used on high-line versions of this vehicle. The Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 138 CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The horn relay is one of the hard wired outputs of the CTM. The high-line CTM is programmed to energize or deenergize the horn relay in response to certain inputs from the Remote Keyless Entry (RKE) system and/or the Vehicle Theft Security System (VTSS). Refer to Remote Keyless Entry System Description. Refer to Vehicle Theft Security System Description for more information on the VTSS. Both the base and the high-line versions of the CTM support the intermittent wipe and wipe-after-wash features, but only the high-line CTM supports the speed sensitive intermittent wipe. The intermittent wipe relay is one of the outputs that both the base and the high-line versions of the CTM can control. Each CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the high-line CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The high-line CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The high-line CTM receives hard-wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch while the driver door is open if the key is in the ignition and/or the headlamps are on. However, the locks can still be operated manually, with a key, or energized with the RKE transmitter. - A Panic Mode feature which can provide additional personal security and protection. When the Panic button on the RKE transmitter is depressed the vehicle horn will pulse, the headlights will flash, and the interior lights will illuminate on the vehicle for about three minutes, or until the Panic button is depressed a second time. A vehicle speed of about 24 kilometers-per-hour (15 miles-per-hour) will also cancel the panic mode. - An enhanced accident response feature will unlock both doors, then prevent the power door locks from locking the doors for a predetermined time interval, after receiving a CCD message from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course, these responses are dependent upon functional battery power and wiring circuitry following the impact. - Rolling door locks is a programmable feature of the power lock system. This feature will automatically lock all of the doors after the vehicle reaches a speed of about 24 kilometers-per-hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour). - A programmable feature of the RKE system is the enabling or disabling of the horn chirp following activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the horn chirp duration (twenty or forty milliseconds) can be selected. One of the features that the high-line CTM supports and controls is the Vehicle Theft Security System (VTSS). In the VTSS, the CTM receives hard- wired inputs from the door jamb, door lock cylinder, and ignition switches. The programming in the CTM allows it to process the information from these inputs and send control outputs to energize or de-energize the headlamp relay, horn relay, and the security lamp. The CTM also sends CCD data bus messages to the Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS. The high-line CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry (RKE) systems, which are integrated into the arming, disarming, and triggering functions of the VTSS. The programmable features of the CTM can be enabled or disabled using the DRB scan tool as described in the proper Diagnostic Procedures. Refer to Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the highline version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. This information covers the diagnosis and service of only the hard-wired inputs used by the CTM to determine that a chime tone should be generated. See Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced.

The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 +12 chimes per minute for reminders and High; 180 + 12 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: Ignition off, key in ignition, driver's door open - Ignition off, headlamps on, driver's door open - Seat belt warning - Check engine lamp illuminated (after prove-out) - Airbag lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out if equipped) - Check gauges lamp illuminated - Low fuel warning lamp illuminated - Low washer fluid Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 141 Central Timer Module ( CTM ) High Option: Description and Operation Airbag System AIRBAG SYSTEM The airbag system is designed to provide increased driver and passenger protection if the vehicle is involved in a front end collision. The system is most effective when used in conjunction with the seat belt system. The airbag control module (ACM) is an electronic module that monitors the airbag system for proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and contains the sensor and actuator that is responsible for airbag deployment. There are no external impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck at the bottom of the instrument panel. It is located forward of the console. The ACM provides diagnostic information (DTCs) to the technician through the DRB III(R) via the CCD bus.Some circuits are tested continuously; others are checked only under certain circumstances. The warning lamp is driven with messages relayed to the Mechanical Instrument Cluster (MIC) from the ACM via the CCD bus. The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be observed by the customer. Whenever the ignition key is turned to the "run" or "start" position,the airbag control module performs a lamp check by turning the AIRBAG warning lamp on for 6 - 8 seconds. If the lamp remains off, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains on, there could be an active fault in the system or the circuit that operates the lamp may be shorted to ground. If the lamp comes on and stays on for a period longer than 6-8 seconds, then goes off, there is usually an intermittent problem in the system. Perform the WARNING LAMP CIRCUIT OPEN procedure (refer to Testing and Inspection in this section) to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. Interior Lighting INTERIOR LIGHTING The courtesy lights are controlled by the CTM. The door switches are inputs to the CTM and the courtesy lights are outputs. The glove box lamp and the ash receiver lamp (if equipped) are not controlled by the CTM. They are hardwired to individual switches and fuses. The highline CTM also provides for illuminated entry option. If the CTM detects an unlock signal from the RKE transmitter, a door disarm switch input or the door jamb switch input, the interior courtesy lights will be turned on. The illuminated entry function is canceled if the CTM senses an ignition "on" condition or the "lock" command from a valid key fob If a door is left open or turned on by rotation of dimmer switch for more than fifteen minutes, the CTM will extinguish the lamps to avoid discharging the battery. If the lamps are turned on by courtesy lamp switch, the CTM will not be able to turn them off. Central Timer Module CENTRAL TIMER MODULE The Dakota (AN) utilizes a Central Timer Module (CTM). This system is available in a Base or Highline configuration. The Base CTM does not communicate on the CCD bus and will not be addressed. For concerns about the Base CTM, please refer to the appropriate Service Manual. The CTM performs most of the typical functions a Body Control Module would perform. The Highline CTM provides the following features: Remote Keyless Entry (RKE) - Chime - Courtesy Lamp Controls/Illuminated Entry - Power Door Locks - Speed Sensitive Intermittent Wipers - Enhanced Accident Response - Vehicle Theft Security System (VTSS) The module is located on the right side of the glove box behind a metal bracket. It contains a white 18-way and a green 14-way connector.

The base version of the CTM is used on base models of the vehicle. The base version of the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, and an ignition lamp time delay relay in a single unit. The high-line version of the CTM is used on highline vehicles. The high-line CTM provides all of the functions of the base version CTM, but also is used to control and integrate many of the additional electronic functions and features included on the high-line models. The high-line version of the CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, reduce internal controller hardware, and reduce component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many new feature capabilities. One of the functions and features that both versions of the CTM support is the chime warning system. The CTM contains a chime tone generator to perform the functions of the chime warning module. The CTM uses hard-wired switch inputs, internal programming, and a hard-wired chime request input from the instrument cluster circuitry to detect when a chime tone is required. Both versions of the CTM are mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening. For diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The high-line Central Timer Module (CTM) can also control some features of the audio system when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The RAZ radio receiver with a remote radio switch option is one of the features that the CTM controls. The CTM is programmed to send switch status messages over the Chrysler Collision Detection (CCD) data bus to control the volume, seek, and pre-set station advance functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch status messages to the radio receiver. The electronic circuitry within the radio receiver responds to the switch status messages it receives by adjusting the radio settings as requested. Refer to Remote Radio Switch in the Description and Operation for more information on this component. In addition, radio receivers connected to the CCD data bus have several audio system functions that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more information on DRB testing of the audio systems. The high-line Central Timer Module (CTM) can also operate the horn system. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The horn relay is one of the hard wired outputs of the CTM. The high-line CTM is programmed to energize or deenergize the horn relay in response to certain inputs from the Remote Keyless Entry (RKE) system and/or the Vehicle Theft Security System (VTSS). Refer to Remote Keyless Entry System Description. Refer to Vehicle Theft Security System Description for more information on the VTSS. Both the base and the high-line versions of the CTM support the intermittent wipe and wipe-after-wash features, but only the high-line CTM supports the speed sensitive intermittent wipe. The intermittent wipe relay is one of the outputs that both the base and the high-line versions of the CTM can control. Each CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the high-line CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The high-line CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The high-line CTM receives hard-wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 143 programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch while the driver door is open if the key is in the ignition and/or the headlamps are on. However, the locks can still be operated manually, with a key, or energized with the RKE transmitter. - A Panic Mode feature which can provide additional personal security and protection. When the Panic button on the RKE transmitter is depressed the vehicle horn will pulse, the headlights will flash, and the interior lights will illuminate on the vehicle for about three minutes, or until the Panic button is depressed a second time. A vehicle speed of about 24 kilometers-per-hour (15 miles-per-hour) will also cancel the panic mode. - An enhanced accident response feature will unlock both doors, then prevent the power door locks from locking the doors for a predetermined time interval, after receiving a CCD message from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course, these responses are dependent upon functional battery power and wiring circuitry following the impact. - Rolling door locks is a programmable feature of the power lock system. This feature will automatically lock all of the doors after the vehicle reaches a speed of about 24 kilometers-per-hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour). - A programmable feature of the RKE system is the enabling or disabling of the horn chirp following activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the horn chirp duration (twenty or forty milliseconds) can be selected. One of the features that the high-line CTM supports and controls is the Vehicle Theft Security System (VTSS). In the VTSS, the CTM receives hard- wired inputs from the door jamb, door lock cylinder, and ignition switches. The programming in the CTM allows it to process the information from these inputs and send control outputs to energize or de-energize the headlamp relay, horn relay, and the security lamp. The CTM also sends CCD data bus messages to the Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS. The high-line CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry (RKE) systems, which are integrated into the arming, disarming, and triggering functions of the VTSS. The programmable features of the CTM can be enabled or disabled using the DRB scan tool as described in the proper Diagnostic Procedures. Refer to Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the highline version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. This information covers the diagnosis and service of only the hard-wired inputs used by the CTM to determine that a chime tone should be generated. See Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. OPERATION Some of the functions and features that the CTM supports or controls include: Chimes for the following conditions: - Headlamps on with ignition off and driver door open warning - Key in ignition with ignition off and driver door open warning - ABS lamp warning (if the vehicle is so equipped) - Airbag lamp warning - Check gauges lamp warning - Low fuel lamp warning - Low washer fluid lamp warning - Seat belt reminder lamp warning - Transmission oil temperature lamp warning (automatic transmission) - Courtesy lamp time-out (high-line only) - Intermittent wipe control - Enhanced accident response (high-line only) - Horn chirp upon door lock with RKE (customer programmable) (high-line only) - Illuminated entry (high-line only) - Power door lock control (high-line only) - Power lock inhibit (high-line only) - Remote Keyless Entry (RKE) (high-line only) - Remote radio switches (high-line only) - Rolling door locks (customer programmable) (high-line only) Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 144 - Speed sensitive intermittent wipe (high-line only) - Vehicle Theft Security System (VTSS) (high-line only) (if the vehicle is so equipped) - Wipe after wash (high-line only).

Chime System CHIME SYSTEM The chime system is built into the CTM. The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 +12 chimes per minute for reminders and High; 180 + 12 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: Ignition off, key in ignition, driver's door open - Ignition off, headlamps on, driver's door open - Seat belt warning - Check engine lamp illuminated (after prove-out) - Airbag lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out if equipped) - Check gauges lamp illuminated - Low fuel warning lamp illuminated - Low washer fluid Compass Mini-Trip Computer (CMTC) COMPASS MINI-TRIP COMPUTER (CMTC) This system, located in the overhead console, displays information on outside temperature, compass direction and trip information. Compass And Temperature Display This display provides the outside temperature and one of eight compass readings to indicate the direction the vehicle is facing. Trip Odometer (ODO) Shows the distance traveled since the last reset. Average Fuel Economy (AVE ECO) Shows the average fuel economy in MPG (miles per gallon) or L/100Km since the last reset. Instantaneous Fuel Economy Shows the fuel economy for the last few seconds in MPG or L/100Km. Distance to Empty (DTE) Shows the estimated distance that can be traveled with the fuel remaining in the tank. This is calibrated using the MPG for the last few minutes. Elapsed Time (ET) Shows the accumulated ignition on time since the last reset. Step Button Press this button to cycle through all the mini-trip computer displays. US/M Button Press this button to convert all vehicle displays from US to Metric to US. To Reset the Display Press the Step and US/M buttons simultaneously for at least two seconds and all resettable conditions will be reset. This will occur only if a resettable function (AVG ECO,Trip Odometer, ET) is currently being displayed. Automatic Compass Calibration This compass is self calibrating which eliminates the need to manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL symbol will be displayed. After completing three 360' turns in an area free from large metal or metallic objects, the CAL symbol will turn off and the compass will function normally. Compass Variance Compass Variance is the difference between Magnetic North and Geographic North. In some areas of the country, the difference between Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 145 Magnetic and Geographic North is great enough to cause the compass to give false readings. If this occurs, the compass vanance must be set. To set the variance: Turn the ignition ON and set display to Comp./Temp. While pressing the US/M button, press the STEP button for approximately five seconds. The "VAR" symbol will light and the last variance zone number will be displayed. Press the US/Metric Button to select the proper variance zone as shown on the map. Press the Step button to set the new variance zone and resume normal operation. Diagnostics DIAGNOSTICS The CTM is fully addressable with the DRB III(R) and it is the recommended method for diagnosis. The CTM reports 6 Diagnostic Trouble Codes. All of the inputs to the CTM can be read with the DRB and the outputs can be actuated. DRB III Error Messages and Blank Screen DRB III(R) ERROR MESSAGES AND BLANK SCREEN Under normal operation, the DRB will display one of only two error messages: User-Requested WARM Boot or User-Requested COLD Boot If the DRB should display any other error message, record the entire display an call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display: ver: 2.14 date: 26 Jul93 file: key itf.cc date: Jul 26 1993 line: 548 err: 0x1 User-Requested COLD Boot Press MORE to switch between this display and the application screen. Press F4 when done noting information. DRB III(R) does not power up (Blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRB may be the result of faulty cable or vehicle wiring. Perform the "Blank Screen" test under Testing and Inspection, Non-Diagnostic Trouble Codes in this section. Display is not visible Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition. Enhanced Accident Response (Highline CTM Only) ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned on when the vehicle speed message on the CCD bus indicates 0 mph or the message is not present. In addition to unlocking the doors, the door lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "off" position, normal operation will resume. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 146 Glossary of Terms/Acronyms GLOSSARY OF ACRONYMS ACM airbag control module CCD Chrysler Collision Detection (vehicle communication bus) DAB driver airbag DLC data link connector EM entry module PAB passenger airbag PCM powertrain control module PDC power distribution center SQUIB also called indicator (located in rear of airbag module) Mechanical Instrument Cluster (MIC) MECHANICAL INSTRUMENT CLUSTER (MIC) The MIC is available in 4 different versions. Two of the versions are Canadian clusters. There is a highline and a low line cluster available. The difference is the addition of a tachometer in the highline. In order to accomplish this, the fuel level gauge is reduced in size and oil pressure gauge is relocated. The cluster positions it's gauges with bus messages received from the PCM. The odometer is a Liquid Crystal Display (LCD). The cluster will provide bus bias and the PCM provides termination. The MIC has an internal diagnostic routing that can be accessed by pushing and holding the trip odometer while rotating the key to the on position. The cluster will then place all the gauges at their calibration points and will light all the CCD driven tell-tales. It will also light all the segments of the LCD display for a visual verification check. The MIC can verify communications with the PCM, ID the module, or change the country code by using options 1, 3, or 9 on the DRB III(R) under the MIC menu. If there are faults found during the diagnostic routine, the cluster will report them on the LCD odometer display. For further information about the diagnostic routine and the explanation of the faults, please refer to Instrument Panel, Testing and Inspection. Power Door Lock System POWER DOOR LOCKS The CTM controls the door lock actuator assemblies to handle locking and unlocking with the key fob or interior switch. There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is off, the door is open, and the key is in the ignition. Automatic or "rolling locks" are included as a DRB III(R) or customer programmable feature. If the vehicle is moving approximately 15 mph and approximately 10 degrees of throttle opening is seen by the PCM, (the PCM will send this info to the CTM via the CCD bus) indicating acceleration, the CTM will cycle the lock actuators to lock the doors. Remote Keyless Entry (RKE) /Vehicle Theft Security System (VTSS) RKE/VTSS If the vehicle is equipped with Remote Keyless Entry (RKE), programming of additional transmitters and horn chirp are customer programmable features. The highline CTM provides for RKE and the Vehicle Theft Security System (VTSS). The base CTM is not able to provide these functions. The presence of either of these options dictates that the vehicle is equipped with a highline CTM. The VTSS system monitors the door ajar switches and ignition switch to detect unauthorized entry into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to start the engine, it will start and stall, If the trigger condition is still present, the lights will continue to flash for an additional 15 minutes After 15 minutes the system will stop pulsing the lights and return to the "armed" state.The cause of the last 4 alarm triggers is stored by the CTM and may be retrieved by the DRB III(R).The system may be disarmed by either an unlock command from a valid RKE key fob or by using a key in either door. Both front door key cylinders are equipped with disarm switches. There is also a VTSS lamp on the dash that provides information to the driver about the state of the vehicle theft system. The RKE system is placed in the programming mode by the DRB III(R), or by using the customer programming sequence. The system will store up to four key fob codes. Two fobs are supplied with the truck, additional fobs may be purchased through parts department. The additional fobs can be programmed with the DRB III(R), or by using the customer programming sequence. Through the DRB III(R), erasing and programming of one key fob without deleting the others is possible. If the key fob is stolen, all the fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense of security.

There are two additional modules, the Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are performed through the Serial Communication Interface of SCI, the same as previous years. All of the information about the functioning of all the systems is organized controlled, and communicated by the CCD bus, which is described in (CCD Bus) of this general information. Through the CCD bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require all the information to perform it's function. It will only respond to messages "addressed" to it through a binary coding process. This method of data transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. Airbag Trouble Code Types and Descriptions AIRBAG DIAGNOSTIC TROUBLE CODES Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists,diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this book to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRB, The procedure begins with AIRBAG TEST 1A-Identifying Airbag System Problems. This will direct you to the specific test(s) that must be performed. Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures, diagnostic trouble codes are used as a diagnostic tool. Active Codes The code becomes active as soon as the malfunction is detected and stored after one minutes of occurrence or key-off, whichever occurs first. An active trouble code indicates an on-going malfunction. This means that the defect is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present. Stored Codes Airbag codes are automatically stored in the ACM's memory after one minute of occurrence or when the ignition is turned off. The exception is the "Loss of Ignition Run Only" code which is an active code only. A "stored" code indicates there was an active code present at some time. However, the code currently may not be present as an active code, although another active code could be. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 148 If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem. In this case, the stored code can indicate an area to inspect. If no obvious problems are found, erase stored codes, and with the "on" wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is difficult to locate. Airbag Diagnostic Trouble Codes The airbag control module may report any of the following diagnostic trouble codes. For the following codes, replace the Airbag Control Module (ACM) even if set intermittently: ACM Accelerometer - Internal Diagnostic 1 - Internal Diagnostic 2 For the following codes, replace the airbag control module (ACM): ACM Output Driver - ACM Stored Energy Logic - ACM Stored Energy Driver - ACM Stored Energy Passenger - Internal Diagnostic 3 - Internal Diagnostic 4 - Safing Sensor Shorted - Warning Lamp Driver Error For these codes, refer to the appropriate diagnostic procedure: Driver Squib Open Driver Squib Shorted Loss of Ignition Run Only Loss of Ignition Run/Start No CCD Communication Passenger Squib Circuit Open Passenger Squib Circuit Shorted Either Squib Terminal Short to Battery Either Squib Terminal Short to Ground Warning Lamp Circuit Open Warning Lamp Circuit Shorted Central Timer Module Diagnostic Trouble Codes CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODES Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure Vehicle Communication VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the highest priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a "voltage divider network" located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems may use more than one. Some modules are capable of both biasing and terminating. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. In this vehicle, the bias is supplied by the instrument cluster and termination is provided by the PCM and the instrument cluster. Without termination,voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLE'S ON-BOARD Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 149 DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING. IF THERE IS A PROBLEM, REFER TO TESTING AND INSPECTION IN THIS SECTION. BUS FAILURE MESSAGES Short to Battery - Either or both of the bus wires are shorted to the battery potential. Or open ground to any CCD bus module. Short to 5 Volts - Either or both of the bus wires are shorted to a 5 volt potential. Short to Ground - Either or both of the bus wires are shorted to ground. Bus (+) & (-) Shorted Together - The two bus wires are shorted together. No Termination - The bus system has lost connection with all of its terminators. Bus Bias Level Too Low - Either or both of the bus wire potentials are significantly below their normal 2.5 volts. Bus Bias Level Too High - Either or both of the bus wire potentials are significantly above their normal 2.5 volts. No Bus Bias - The bus system has lost connection with Instrument Cluster. Bus (+) Open - The bus (+) wire has lost connection with termination and/or bias. Bus (-) Open - The bus (-) wire has lost connection with termination and/or bias. Not Receiving Bus Messages Correctly - The DRB cannot communicate over the bus and does not know why. Warnings WARNINGS Vehicle Damage Warnings Before disconnecting any control module, make sure the ignition is "off". Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side(not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. Road testing a complaint vehicle Some of the complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition. CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE REASSEMBLED. DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION. DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR OPERATE IT YOURSELF. HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB. Wiper System SPEED SENSITIVE INTERMITTENT WIPERS The AN truck equipped with a highline CTM will utilize speed sensitive intermittent wipers. Only a highline CTM will be able to support this feature. A base CTM will provide for intermittent wipers without the speed sensitive feature. The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, an immediate wipe of the windshield takes place and the new delay interval is implemented. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Testing and Inspection > Reading and Clearing Diagnostic Trouble Codes Central Timer Module ( CTM ) High Option: Reading and Clearing Diagnostic Trouble Codes With Scan Tool Data Link (Diagnostic) Connector Location Technicians must retrieve stored DTC's by connecting the DRB scan tool (or an equivalent scan tool) to the 16-way data link connector.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 211 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 212 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 213 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 214 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 215 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 216 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number for the subsequent diagram will match a listed group shown. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 217 Connector and Terminal Replacement 1.

Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 228 Powertrain Control Module: Connector Views Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 229 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Page 230 Powertrain Control Module: Description and Operation Powertrain Control Module (PCM) The Powertrain Control Module (PCM) is located in the engine compartment. The ignition system is controlled by the PCM. NOTE: Base ignition timing by rotation of distributor is not adjustable on any of these engines. The PCM opens and closes the ignition coil ground circuit to operate the ignition coil. This is done to adjust ignition timing, both initial (base) and advance, and for changing engine operating conditions. The amount of electronic spark advance provided by the PCM is determined by five input factors: engine coolant temperature, engine rpm, intake manifold temperature, manifold absolute pressure and throttle position. Speed Control Operation The speed control electronic control circuitry is integrated into the PCM. The PCM speed control functions are monitored by the On-Board Diagnostics (OBD). All OBD-sensed systems are monitored by the PCM. Each monitored circuit is assigned a Diagnostic Trouble Code (DTC). The PCM will store a DTC in electronic memory for certain failures it detects. See On-Board Diagnostic Test For Speed Control System for more information. The PCM cannot be repaired and must be replaced if faulty. PCM Control of Automatic Transmission The PCM controls operation of the converter clutch, overdrive clutch, and governor pressure solenoid. The control module determines transmission shift points based on input signals from the transmission thermistor, transmission output shaft speed sensor, crankshaft position sensor, vehicle speed sensor, throttle position sensor, and battery temperature sensor. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Page 231 Powertrain Control Module: Service and Repair PCM Location And Mounting The PCM is located in the engine compartment.

The ACM contains an electronic microprocessor, an electronic impact sensor, an electromechanical safing sensor, and an energy storage capacitor. The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. OPERATION The microprocessor in the ACM contains the airbag system logic. The airbag system logic includes On-Board Diagnostics (OBD), and the ability to communicate with the instrument cluster circuitry over the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor continuously monitors all of the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster over the CCD data bus to turn on the airbag indicator lamp. Refer to Instrument Cluster in the Instrument Panel Systems for more information on the airbag indicator lamp. One electronic impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate as signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbags. In addition to the electronic impact sensor, there is an electromechanical sensor within the ACM called a safing sensor. The safing sensor is a normally open series switch located in the airbag deployment circuit of the ACM. This sensor detects impact energy of a lesser magnitude than the electronic impact sensor, and must be closed in order for the airbags to deploy The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags for up to one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact, if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Restraint Systems > Air Bag Control Module > Component Information > Specifications > Page 269 Air Bag Control Module: Service and Repair WARNING: - THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG.

The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. See the fuse and relay layout label affixed to the inside surface of the PDC cover for starter relay identification and location. The starter relay is a International Standards Organization (ISO) micro-relay. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. The ISO micro-relay terminal functions are the same as a conventional ISO relay However, the ISO micro-relay terminal pattern (or footprint) is different, the current capacity is lower, and the physical dimensions are smaller than those of the conventional ISO relay. The starter relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one movable) electrical contacts. The movable (common feed) relay contact is held against one of the fixed contacts (normally closed) by spring pressure. When the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Starting and Charging > Starter Relay > Component Information > Locations > Page 278 Starter Relay: Testing and Inspection Starter Relay The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. Refer to the fuse and relay layout label affixed to the underside of the PDC cover for starter relay identification and location. 1. Remove the starter relay from the PDC. Refer to Starter Relay Replacement for the procedures. 2. A relay in the de-energized position should have continuity between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go to Step 3. If not OK, replace the faulty relay 3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to Step 4. If not OK, replace the faulty relay 4. Connect a battery to terminals 85 and 86. There should now be continuity between terminals 30 and 87, and no continuity between terminals 87A and 30. If OK, perform the Relay Circuit Test that follows. If not OK, replace the faulty relay. Relay Circuit Test 1. The relay common feed terminal cavity (30) is connected to battery voltage and should be hot at all times. If OK, go to Step 2. If not OK, repair the open circuit to the fuse in the PDC as required. 2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized position, but is not used for this application. Go to Step 3. 3. The relay normally open terminal (87) is connected to the common feed terminal (30) in the energized position. This terminal supplies battery voltage to the starter solenoid field coils. There should be continuity between the cavity for relay terminal 87 and the starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair the open circuit to the starter solenoid as required. 4. The coil battery terminal (86) is connected to the electromagnet in the relay. It is energized when the ignition switch is held in the Start position. On vehicles with a manual transmission, the clutch pedal must be fully depressed for this test. Check for battery voltage at the cavity for relay terminal 86 with the ignition switch in the Start position, and no voltage when the ignition switch is released to the On position. If OK, go to Step 5. If not OK with an automatic transmission, check for an open or short circuit to the ignition switch and repair, if required. If the circuit to the ignition switch is OK, refer to Ignition Switch and Key Lock Cylinder Diagnosis. If not OK with a manual transmission, check the circuit between the relay and the clutch pedal position switch for an open or a short. If the circuit is OK, refer to Clutch Pedal Position Switch Diagnosis. 5. The coil ground terminal (85) is connected to the electromagnet in the relay. On vehicles with a manual transmission, it is grounded at all times. On vehicles with an automatic transmission, it is grounded through the park/neutral position switch only when the gearshift selector lever is in the Park or Neutral positions. Check for continuity to ground at the cavity for relay terminal 85. If not OK with a manual transmission, repair the circuit to ground as required. If not OK with an automatic transmission, check for an open or short circuit to the park/neutral position switch and repair, if required. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Starting and Charging > Starter Relay > Component Information > Locations > Page 279 Starter Relay: Service and Repair REMOVAL 1.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

A sensor is mounted to each front steering knuckles. The third sensor is mounted on top of the rear axle differential housing. The sensor is a magnet coil that is mounted over a tone wheel front/exciter ring rear with an air gap between them. The sensors measure the wheel speed by monitoring the rotation of the tone wheels front/exciter ring rear. As the teeth of the tone wheels front/exciter ring rear move through the magnetic field of the sensor an AC voltage is generated. This signal frequency increases or decreases proportionally to the speed of the wheel. The CAB monitors these signals for changes in wheel deceleration. If the CAB detects a sudden wheel or wheels deceleration within a predetermined amount the CAB will activate the ABS system. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Brakes and Traction Control > Wheel Speed Sensor > Component Information > Description and Operation > Four Wheel Antilock Brakes > Page 386 Wheel Speed Sensor: Description and Operation Rear Wheel Antilock Brakes Rear Wheel Speed Sensor Location The rear Wheel Speed Sensor (WSS) is mounted in the rear differential housing. The WSS consists of a magnet surrounded by windings from a single strand of wire. The sensor sends a small AC signal to the CAB. This signal is generated by magnetic induction. The magnetic induction is created when a toothed sensor ring (exciter ring or tone wheel) passes the stationary magnetic WSS. Exciter Ring Location The exciter ring is press fitted onto the differential carrier next to the final drive ring gear. For replacement procedure of the exciter ring, refer to Transmission and Drivetrain. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Brakes and Traction Control > Wheel Speed Sensor > Component Information > Description and Operation > Four Wheel Antilock Brakes > Page 387 Operation Of The Wheel Speed Sensor When the ring gear is rotated, the exciter ring passes the tip of the WSS. As the exciter ring passes the tip of the WSS, the magnetic lines of force of the sensor are cut, causing the magnetic field to be moved across the sensor's windings. This, in turn causes current to flow through the WSS circuit. Every time a tooth of the exciter ring passes the tip of the WSS, an AC signal is generated. Each AC signal (positive to negative signal or sinewave) is interpreted by the CAB. It then compares the frequency of the sinewave to a time value to calculate vehicle speed. The CAB continues to monitor the frequency to determine a deceleration rate that would indicate a possible wheel-locking tendency. The signal strength of any magnetic induction sensor is directly affected by: Magnetic field strength; the stronger the magnetic field, the stronger the signal - Number of windings in the sensor; more windings provide a stronger signal - Exciter ring speed; the faster the exciter ring rotates, the stronger the signal will be - Distance between the exciter ring teeth and WSS; the closer the WSS is to the exciter ring, the stronger the signal will be The rear WSS is not adjustable. A clearance specification has been established for manufacturing tolerances. If the clearance is not within these specifications, then either the WSS or other components may be damaged. The clearance between the WSS and the exciter ring is 0.005-0.050 inch. Data Link Connector - Typical The assembly plant performs a "Rolls Test" on every vehicle that leaves the assembly plant. One of the tests performed is a test of the WSS. To properly test the sensor, the assembly plant connects test equipment to the Data Link Connector (DLC). This connector is located to the right of the steering column and attached to the lower portion of the instrument panel. The rolls test terminal is spliced to the WSS circuit. The vehicle is then driven on a set of rollers and the WSS output is monitored for proper operation. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Brakes and Traction Control > Wheel Speed Sensor > Component Information > Service and Repair > Wheel Speed Sensor Replacement Wheel Speed Sensor: Service and Repair Wheel Speed Sensor Replacement Front CAUTION: Special bolts are used to attach the front sensor.

The sensor provides an input voltage to the powertrain control module (PCM) relating coolant temperature. The PCM uses this input along with inputs from other sensors to determine injector pulse width and ignition timing. As coolant temperature varies, the coolant temperature sensor resistance will change. This change in resistance results in a different input voltage to the PCM. When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air-fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 402 Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection To perform a complete test of the engine coolant temperature sensor and its circuitry, refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures.

The two switch modules are labeled: ON/OFF SET, RESUME/ACCEL, CANCEL and COAST. Refer to the owner's manual for more information on speed control switch functions and setting procedures. The individual switches cannot be repaired. If one individual switch fails, the switch module must be replaced. OPERATION Within the two switch modules, five momentary contact switches, supporting seven different speed control functions are used. The outputs from these switches are filtered into one input. The Powertrain Control Module (PCM) determines which output has been applied through resistive multiplexing. The input circuit voltage is measured by the PCM to determine which switch function has been selected. A speed control indicator lamp, located on the instrument panel cluster is energized by the PCM via the CCD Bus. This occurs when speed control system power has been turned ON, and the engine is running. SPEED CONTROL SWITCHES-PCM INPUT Six different speed control functions, using three momentary contact switches, are monitored through this multiplexed input. The resistance monitored at this input, in combination with the length of time the PCM measures the resistance, determines which switch feature has been selected. The three switches are: On/Off, Set/Coast, Cancel and Resume/Accelerate. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Cruise Control > Cruise Control Switch > Component Information > Diagrams > Page 418 Cruise Control Switch: Service and Repair REMOVAL WARNING: BEFORE BEGINNING ANY AIRBAG SYSTEM COMPONENT REMOVAL OR INSTALLATION, REMOVE AND ISOLATE THE NEGATIVE (-) CABLE FROM THE BATTERY.

The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a screw to the right side of the radiator yoke, behind the radiator grille and in front of the engine compartment. The ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be replaced. OPERATION The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal sent to it by the compass mini-trip computer module. The resistance in the sensor changes as temperature changes, changing the temperature sensor signal circuit voltage to the compass mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip computer module senses a specific voltage on the temperature sensor signal circuit, which it is programmed to correspond to a specific temperature. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - HVAC > Ambient Temperature Sensor / Switch HVAC > Component Information > Specifications > Page 438 Ambient Temperature Sensor / Switch HVAC: Testing and Inspection The thermometer function is supported by the ambient temperature sensor, a wiring circuit, and a portion of the compass mini-trip computer module. If any portion of the ambient temperature sensor circuit fails, the compass/thermometer display function will self-diagnose the circuit. An "SC" (short circuit) will appear in the display in place of the temperature, when the sensor is exposed to temperatures above 110° C (230° F), or if the sensor circuit is shorted. An "OC" (open circuit) will appear in the display in place of the temperature, when the sensor is exposed to temperatures below 50° C (-58° F), or if the sensor circuit is open. The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test, and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the temperature display is inoperative or incorrect, refer to Compass Mini-Trip Computer in the Diagnosis and Testing. Sensor Test 1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the ambient temperature sensor wire harness connector. 2. Measure the resistance of the ambient temperature sensor. At -40° C (-40° F), the sensor resistance is 336 K Ohms. At 55° C (131° F), the sensor resistance is 2.488 K Ohms. The sensor resistance should read between these two values. If OK, refer to Sensor Circuit Test in the Diagnosis and Testing. If not OK, replace the faulty ambient temperature sensor. Sensor Circuit Test 1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable.

The switch is screwed onto an accumulator fitting that contains a Schrader-type valve, which allows the switch to be serviced without discharging the refrigerant system. The accumulator fitting is equipped with an O-ring to seal the switch connection. The low pressure cycling clutch switch is connected in series electrically with the high pressure cut-off switch and the heater-A/C controls, between ground and the Powertrain Control Module (PCM). The switch contacts open and close causing the PCM to turn the compressor clutch on and off. This regulates the refrigerant system pressure and controls evaporator temperature. Controlling evaporator temperature prevents condensate water on the evaporator fins from freezing and obstructing air conditioning system air flow. The low pressure cycling clutch switch contacts are open when the suction pressure is about 141 kPa (20.5 psi) or lower. The switch contacts will close when the suction pressure rises to about 234 to 262 kPa (34 to 38 psi) or above. Lower ambient temperatures, below about -1° C (30° F), will also cause the switch contacts to open. This is due to the pressure/temperature relationship of the refrigerant in the system. The low pressure cycling clutch switch is a factory-calibrated unit. It cannot be adjusted or repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - HVAC > Refrigerant Pressure Sensor / Switch, HVAC > Low Pressure Sensor / Switch, HVAC > Component Information > Locations > Page 457 Low Pressure Sensor / Switch: Testing and Inspection Before performing diagnosis of the low pressure cycling clutch switch, be certain that the switch is properly installed on the accumulator fitting. If the switch is too loose it may not open the Schrader-type valve in the accumulator fitting, which will prevent the switch from correctly monitoring the refrigerant system pressure. Remember that lower ambient temperatures, below about -1° C (30° F), during cold weather will open the switch contacts and prevent compressor operation due to the pressure/temperature relationship of the refrigerant. Also verify that the refrigerant system has the correct refrigerant charge. See Refrigerant System Charge in the Service Procedures for more information. 1.

The sending unit consists of a float, an arm, and a variable resistor (track). The resistor track is used to send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for OBD II emission requirements. For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and arm move down. This increases the sending unit resistance causing the fuel gauge to read empty. After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading. For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the sending unit to the PCM to indicate fuel level. The purpose of this feature is to prevent the OBD II system from recording/setting false misfire and fuel system monitor trouble codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will also be activated if the fuel level in the tank is more than approximately 85 percent of its rated capacity. Fuel Tank/Fuel Pump Module Fuel Pump Module Components (Typical Pump Module Shown) FUEL PUMP MODULE The fuel pump module on all models/all engines is installed in the top of the fuel tank. The fuel pump module contains the following components: A combination fuel filter/fuel pressure regulator - Electric fuel pump - Fuel pump reservoir - A separate in-tank fuel filter (at bottom of module) Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 474 - Fuel gauge sending unit (fuel level sensor) - Fuel supply line connection at filter/regulator - A threaded locknut retain pump module to fuel tank - A gasket between tank flange and module The fuel gauge sending unit (fuel level sensor), and pick-up filter (at bottom of module) may be serviced separately.

The switch is also used to send signals to components that must know when the brakes are applied, such as the Powertrain Control Module (PCM), which uses the signal to cancel speed control. The CAB uses the brake switch signal to monitor brake pedal application. When the switch contacts open (brakes applied), the CAB receives the brake applied signal. The CAB then monitors the RWAL system to anticipate the need for an RWAL stop. When the brake light switch is activated, the Powertrain Control Module (PCM) receives an input indicating that the brakes are being applied. After receiving this input, the PCM maintains idle speed to a scheduled rpm through control of the Idle Air Control (IAC) motor. The brake switch input is also used to disable vent and vacuum solenoid output signals to the speed control servo. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Lighting and Horns > Brake Light Switch > Component Information > Description and Operation > With Antilock Brakes > Page 494 Brake Light Switch: Description and Operation With Standard Brakes The content of this article reflects the changes called out by TSB 26-05-99.

The only visible parts of the multi-function switch are the control stalk that extends from the left side of the steering column, and the hazard warning switch push button that protrudes from the top of the steering column. The multi-function switch control stalk has both nomenclature and international control symbols on it, which identify its many functions. The hazard warning switch push button is identified with a double triangle, which is the international control symbol for hazard warning. The remainder of the multi-function switch is concealed beneath the steering column shrouds. The multi-function switch also contains circuitry for the following functions: Headlamp beam selection - Headlamp optical horn - Windshield wipers - Windshield washers. The information contained addresses only the multi-function switch turn signal and hazard warning functions. However, the turn signal and hazard warning switches cannot be repaired. If these switches or any other circuit or component of the multi-function switch unit is faulty or damaged, the entire Multifunction switch unit must be replaced. OPERATION The hazard warning switch is controlled by the hazard warning switch push button. Push the switch button in to unlatch the switch and activate the hazard warning system, and push in on the button again to latch the switch and turn the system off. When the hazard warning switch is latched (hazard warning off), the push button will be in a lowered position on the top of the steering column shroud; and, when the hazard warning switch is unlatched (hazard warning on), the push button will be in a raised position. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Lighting and Horns > Hazard Warning Switch > Component Information > Specifications > Page 515 Hazard Warning Switch: Testing and Inspection The turn signal switch and the hazard warning switch are integral to the multi-function switch.

The switch consists of two plastic membranes, one that is flat and one that is slightly convex. These two membranes are secured to each other around the perimeter. Inside the switch, the centers of the facing surfaces of these membranes each has a grid made with an electrically conductive material applied to it. One of the grids is connected to a circuit that provides it with continuity to ground at all times. The grid of the other membrane is connected to the horn relay control circuit. The steering wheel and steering column must be properly grounded in order for the horn switch to function properly. The horn switch is only serviced as a part of the driver side airbag module trim cover. If the horn switch is damaged or faulty, or if the driver side airbag is deployed, the driver side airbag module trim cover and horn switch must be replaced as a unit. OPERATION When the center area of the driver side airbag trim cover is depressed, the electrically conductive grids on the facing surfaces of the horn switch membranes contact each other, closing the switch circuit. The completed horn switch circuit provides a ground for the control coil side of the horn relay, which activates the relay. When the horn switch is released, the resistive tension of the convex membrane separates the two electrically conductive grids and opens the switch circuit. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Lighting and Horns > Horn Switch > Component Information > Locations > Page 535 Horn Switch: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The only visible parts of the multi-function switch are the control stalk that extends from the left side of the steering column, and the hazard warning switch push button that protrudes from the top of the steering column. The multi-function switch control stalk has both nomenclature and international control symbols on it, which identify its many functions. The hazard warning switch push button is identified with a double triangle, which is the international control symbol for hazard warning. The remainder of the multi-function switch is concealed beneath the steering column shrouds. The multi-function switch also contains circuitry for the following functions: Headlamp beam selection - Headlamp optical horn - Windshield wipers - Windshield washers. The information contained addresses only the multi-function switch turn signal and hazard warning functions. However, the turn signal and hazard warning switches cannot be repaired. If these switches or any other circuit or component of the multi-function switch unit is faulty or damaged, the entire Multifunction switch unit must be replaced. OPERATION The multi-function switch control stalk that extends from the left side of the steering column just below the steering wheel is moved up or down to activate the turn signal switch. When the control stalk is moved in the upward direction, the right turn signal switch circuitry is activated; and, when the control stalk is moved in the downward direction, the left turn signal switch circuitry is activated. The turn signal switch has a detent position in each direction that provides turn signals with automatic cancellation, and an intermediate momentary position in each direction that provides turn signals only until the multi-function switch control stalk is released. When the turn signal switch is in a detent position, it is turned off by one of two turn signal cancelling cam lobes that are integral to the rotor of the clockspring mechanism. Turning the steering wheel causes the turn signal cancelling cam lobes to contact a cancel actuator in the multi-function switch, and the turn signal switch automatically returns to the off position. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Lighting and Horns > Turn Signal Switch > Component Information > Specifications > Page 543 Turn Signal Switch: Testing and Inspection The turn signal switch and the hazard warning switch are integral to the multi-function switch.

The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Camshaft Position Sensor-Typical (Distributor Shown) CAMSHAFT POSITION SENSOR-PCM INPUT A sync signal is provide by the camshaft position sensor. The sensor located in the distributor on all engines. The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Locations > Page 562 Camshaft Position Sensor: Testing and Inspection Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines. To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain Diagnostics Procedures service manual. To test the sensor only, refer to the following: For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips. 1. Connect the positive (+) voltmeter lead into the sensor output wire. This is at done the distributor wire harness connector. 2. Connect the negative (-) voltmeter lead into the ground wire. 3. Set the voltmeter to the 15 Volt DC scale. 4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup. 5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 6. If voltage is not present, check the voltmeter leads for a good connection. 7. If voltage is still not present, check for voltage at the supply wire. 8. If 5 volts is not present at supply wire, check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for this test. 9. If voltage is still not present, perform vehicle test using the DRB scan tool. 10. If voltage is present at cavity A-17, but not at the supply wire: a. Check continuity between the supply wire. This is checked between the distributor connector and cavity A-17 at the PCM. If continuity is not present, repair the harness as necessary. b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the PCM. If continuity is not present, repair the harness as necessary. c. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary. 11. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. If sync pulse signal is not present, replacement of the camshaft position sensor is necessary. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Locations > Page 563 Camshaft Position Sensor: Service and Repair Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines.

The sensor provides an input voltage to the powertrain control module (PCM) relating coolant temperature. The PCM uses this input along with inputs from other sensors to determine injector pulse width and ignition timing. As coolant temperature varies, the coolant temperature sensor resistance will change. This change in resistance results in a different input voltage to the PCM. When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air-fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 571 Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection To perform a complete test of the engine coolant temperature sensor and its circuitry, refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures.

The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing. The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it. Sensor Operation The flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its outer edge. The notches cause a pulse to be generated when they pass under the sensor. The pulses are the input to the PCM. For each engine revolution, there are 8 pulses generated. The engine will not operate if the PCM does not receive a crankshaft position sensor input. CRANKSHAFT POSITION SENSOR-PCM INPUT This sensor is a hall effect device that detects notches in the flywheel (manual transmission) or flexplate (automatic transmission). This sensor is used to indicate to the powertrain control module (PCM) that a spark and or fuel injection event is to be required. The output from this sensor, in conjunction with the camshaft position sensor signal, is used to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders.

They are: Left, right, pre-catalyst and post catalyst. The left, right and post catalyst sensors will fine-tune air-fuel ratio. The pre-catalyst and post catalyst sensors will determine catalytic converter efficiency. Two of these sensors are installed into the left and right exhaust manifold downpipes. The left O2S sensor will monitor cylinders 1, 3, 5 and 7. The right sensor will monitor cylinders 2, 4, 6 and 8. The sensors produce voltages from 0 to 1 volt, depending upon the oxygen content of the exhaust gas in the exhaust manifold. When a large amount of oxygen is present (caused by a lean air/fuel mixture), the sensors produces a low voltage. When there is a lesser amount present (rich air/fuel mixture) it produces a higher voltage. By monitoring the oxygen content and converting it to electrical voltage, the sensors act as a rich-lean switch. The oxygen sensors are equipped with a heating element that keeps the sensors at proper operating temperature during all operating modes. Maintaining correct sensor temperature at all times allows the system to enter into closed loop operation sooner. Also, it allows the system to remain in closed loop operation during periods of extended idle. In Closed Loop operation, the PCM monitors the O2S sensor input (along with other inputs) and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values and inputs from other sensors. The Automatic Shutdown (ASD) relay supplies battery voltage to both oxygen sensors. The oxygen sensors are equipped with a heating elements. The heating elements reduce the time required for the sensors to reach operating temperature. PRE-CATALYST OXYGEN SENSOR The pre-catalyst O2S sensor is located in the inlet end of the catalytic converter. It provides an input voltage to the PCM. By comparing the input from the pre-catalyst O2S sensor, with the input from the post catalyst oxygen sensor, the PCM calculates catalytic convertor efficiency. POST CATALYST OXYGEN SENSOR The post catalyst heated oxygen sensor threads into the outlet end of the catalytic convertor. The post catalyst heated oxygen sensor input is used to detect catalytic convertor deterioration and fine tune the air fuel ratio. As the convertor deteriorates, the input from this sensor begins to match the pre-catalyst sensor input except for a slight time delay. By comparing the inputs from both of these sensors, the PCM calculates catalytic convertor efficiency. When the catalytic converter efficiency drops below emission standards, the PCM stores a diagnostic trouble code and illuminates the Malfunction Indicator Lamp (MIL). For more information, refer to Emission Control Systems. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Page 619 Oxygen Sensor: Testing and Inspection To perform a complete test of the O2S sensors and their circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 644 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 645 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 646 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 647 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 648 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 659 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 660 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 661 Connector Pin Identification Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Page 662 Vehicle Speed Sensor: Description and Operation VEHICLE SPEED AND DISTANCE-PCM INPUT Vehicle speed and distance covered are measured by the Rear Wheel Speed Sensor. The sensor is mounted to the rear axle. A signal is sent from this sensor to the Controller Antilock Brake (CAB) computer. A signal is then sent from the CAB to the Powertrain Control Module (PCM) to determine vehicle speed and distance covered. The PCM will then determine strategies for fuel system and speed control system operation.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 670 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the TPS only, refer to the following: TPS The TPS can be tested with a digital voltmeter. The center electrical terminal of the TPS is the output terminal. With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT). At idle, TPS output voltage should be greater than 0.26 volts but less than 0.95 volts. At wide open throttle, TPS output voltage must be less than 4.49 volts. The output voltage should increase gradually as the throttle plate is slowly opened from idle to WOT. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 671 Throttle Position Sensor: Service and Repair REMOVAL The TPS is located on side of throttle body. 1.

The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Camshaft Position Sensor-Typical (Distributor Shown) CAMSHAFT POSITION SENSOR-PCM INPUT A sync signal is provide by the camshaft position sensor. The sensor located in the distributor on all engines. The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Locations > Page 678 Camshaft Position Sensor: Testing and Inspection Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines. To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain Diagnostics Procedures service manual. To test the sensor only, refer to the following: For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips. 1. Connect the positive (+) voltmeter lead into the sensor output wire. This is at done the distributor wire harness connector. 2. Connect the negative (-) voltmeter lead into the ground wire. 3. Set the voltmeter to the 15 Volt DC scale. 4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup. 5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 6. If voltage is not present, check the voltmeter leads for a good connection. 7. If voltage is still not present, check for voltage at the supply wire. 8. If 5 volts is not present at supply wire, check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for this test. 9. If voltage is still not present, perform vehicle test using the DRB scan tool. 10. If voltage is present at cavity A-17, but not at the supply wire: a. Check continuity between the supply wire. This is checked between the distributor connector and cavity A-17 at the PCM. If continuity is not present, repair the harness as necessary. b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the PCM. If continuity is not present, repair the harness as necessary. c. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary. 11. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. If sync pulse signal is not present, replacement of the camshaft position sensor is necessary. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Locations > Page 679 Camshaft Position Sensor: Service and Repair Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines.

The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing. The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it. Sensor Operation The flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its outer edge. The notches cause a pulse to be generated when they pass under the sensor. The pulses are the input to the PCM. For each engine revolution, there are 8 pulses generated. The engine will not operate if the PCM does not receive a crankshaft position sensor input. CRANKSHAFT POSITION SENSOR-PCM INPUT This sensor is a hall effect device that detects notches in the flywheel (manual transmission) or flexplate (automatic transmission). This sensor is used to indicate to the powertrain control module (PCM) that a spark and or fuel injection event is to be required. The output from this sensor, in conjunction with the camshaft position sensor signal, is used to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders.

The positioning is accomplished through suspension and steering linkage adjustments. An alignment is considered essential for efficient steering, good directional stability and to minimize tire wear. The most important measurements of an alignment are caster, camber and toe. CASTER is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the knuckle forward provides negative caster. Tilting the top of the knuckle rearward provides positive caster. Positive caster promotes directional stability. This angle enables the front wheels to return to a straight ahead position after turns. - CAMBER is the inward or outward tilt of the wheel relative to the center of the vehicle. Tilting the top of the wheel inward provides negative camber. Tilting the top of the wheel outward provides positive camber. Incorrect camber will cause wear on the inside or outside edge of the tire. TOE is the difference between the leading inside edges and trailing inside edges of the front tires. Wheel toe position out of specification cause's unstable steering, uneven tire wear and steering wheel off-center. The wheel toe position is the final front wheel alignment adjustment. - THRUST ANGLE is the angle of the rear axle relative to the centerline of the vehicle. Incorrect thrust angle can cause off-center steering and excessive tire wear. This angle is not adjustable, damaged component(s) must be replaced to correct the thrust angle. CAUTION: Never attempt to modify suspension or steering components by heating or bending. NOTE: Periodic lubrication of the front suspension/ steering system components may be required. Rubber bushings must never be lubricated. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Page 831 Alignment: Testing and Inspection PRE-ALIGNMENT INSPECTION Before starting wheel alignment, the following inspection and necessary corrections must be completed. 1. Inspect tires for size, air pressure and tread wear. 2. Inspect front wheel bearings for wear. 3. Inspect front wheels for excessive radial or lateral runout and balance. 4. Inspect ball studs, linkage pivot points and steering gear for looseness, roughness or binding. 5. Inspect suspension components for wear and noise. 6. On 4x4 vehicles check suspension height. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Page 832 Alignment: Service and Repair NOTE: 4x4 suspension height measurement must be performed before alignment. CAMBER AND CASTER ADJUSTMENT Caster & Camber Adjustment - Typical Camber and caster angle adjustments involve changing the position of the upper suspension arm pivot bar. On 4x2 vehicles Adjuster C-4576 can be used to make camber/caster adjustments. Caster Moving the rear position of the pivot bar in or out, will change the caster angle significantly and camber angle only slightly. To maintain the camber angle while adjusting caster, move the rear of the pivot bar in or out. Then move the front of the pivot bar slightly in the opposite direction. The caster angle should be adjusted to preferred specification. NOTE: For example, to increase a positive caster angle, move the rear position of the pivot bar inward (toward the engine). Move the front of pivot bar outward (away from the engine) slightly until the original camber angle is obtained. Camber Move the front of the pivot bar in or out. This will change the camber angle significantly and caster angle slightly. The camber angle should be adjusted to preferred specification. After adjustment is made tighten the pivot bar nuts to proper torque specification. TOE ADJUSTMENT The wheel toe position adjustment is the final adjustment. 1. Start the engine and turn wheels both ways before straightening the wheels. Secure the steering wheel with the front wheels in the straight-ahead position. 2. Loosen the tie rod jam nuts. NOTE: Each front wheel should be adjusted for one-half of the total toe position specification. This will ensure the steering wheel will be centered when the wheels are positioned straight-ahead. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Page 833 Toe Adjustment 3. Adjust the wheel toe position by turning the tie rod as necessary. 4. Tighten the tie rod jam nut to 75 Nm (56 ft. lbs.). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Alignment > System Information > Technical Service Bulletins > Page 834 Adjuster Caster/Camber C-4576 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Pressure, Vacuum and Temperature Specifications Fuel Pressure: Pressure, Vacuum and Temperature Specifications Fuel Pressure Engine at curb idle ............................................................................................................................... ........................................ 339 ± 34 kPa (49.2 ± 5 psi) Pressure Leakdown (fuel pump not engaged) .................................................................................................................

Use this test in conjunction with the Fuel Pressure Leak Down Test. 1. Release fuel system pressure. Refer to the Fuel Pressure Release Procedure. 2. Disconnect fuel supply line at fuel rail. Some engines may require air cleaner housing removal before line disconnection. 3. Connect appropriate Fuel Line Pressure Test Adapter Tool Hose (number 6631, 6923, 6541 or 6539) into disconnected fuel supply line. Insert other end of Adaptor Tool hose into a graduated container. 4. Remove fuel fill cap. 5. To activate fuel pump and pressurize system, obtain DRB scan tool and actuate ASD Fuel System Test. 6. A good fuel pump will deliver at least 1/4 liter of fuel in 7 seconds. Do not operate fuel pump for longer than 7 seconds with fuel line disconnected as fuel pump module reservoir may run empty. a. If capacity is lower than specification, but fuel pump can be heard operating through fuel fill cap opening, check for a kinked/damaged fuel supply line somewhere between fuel rail and fuel pump module. b. If line is not kinked/damaged, and fuel pressure is OK, but capacity is low, replace fuel filter/ fuel pressure regulator. The filter/regulator may be serviced separately on certain applications. Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information. c. If both fuel pressure and capacity are low, replace fuel pump module assembly Refer to Fuel Pump Module Removal/Installation. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 841 Fuel Pressure: Testing and Inspection Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity Test. Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: - Fuel pressure bleeding past a fuel injector(s). - Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose. Tool number 6539 is used for 5/16" fuel lines and tool number 6631 is used for 3/8" fuel lines. Connecting Adapter Tool-Typical Connecting Adapter Tool-Typical 3. Connect correct Fuel Line Pressure Test Adapter Tool Hose between disconnected fuel line and fuel rail. 4. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 842 6. Observe test gauge. Normal operating pressure should be 339 kPa ± 34 kPa (49.2 psi ± 5 psi). 7. Shut engine off. 8. Pressure should not fall below 30 psi for five minutes. 9. If pressure falls below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine off. 12. Testing for fuel injector or fuel rail leakage: Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking. 13. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage: Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line. If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump or filter/regulator may be leaking. Note: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A slow loss of pressure usually indicates a defective check valve in the electric fuel pump. The electric fuel pump is not serviced separately. Replace the fuel pump module assembly. The filter/ regulator may be replaced separately on certain applications. Refer to Fuel Filter/Fuel Pressure Regulator Removal/installation for additional information. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Idle Speed > System Information > Specifications Idle Speed: Specifications Minimum Air Flow Idle ......................................................................................................................... ......................................................... 500 to 900 rpm Note: Idle speed range achieved through Minimum Air Flow Idle Test Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Idle Speed > System Information > Specifications > Page 846 Idle Speed: Testing and Inspection The following test procedure has been developed to check throttle body calibrations for correct idle conditions.

These cables transfer electrical current from the ignition coil(s) and/or distributor, to individual spark plugs at each cylinder. The resistive spark plug cables are of nonmetallic construction. The cables provide suppression of radio frequency emissions from the ignition system. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 890 Ignition Cable: Testing and Inspection Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and spark plugs. Terminals should be fully seated. The insulators should be in good condition and should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are cracked or torn must be replaced. Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the cables dry. Check for brittle or cracked insulation. Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable boot and spark plug. These shields protect the spark plug boots from damage (due to intense engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat shield. Testing When testing secondary cables for damage with an oscilloscope, follow the instructions of the equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as follows: CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during testing. This may cause possible heat damage to the catalytic converter. Total test time must not exceed ten minutes. With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to a good engine ground. If the cable and spark plug are in good condition, the engine rpm should drop and the engine will run poorly. If engine rpm does not drop, the cable and/or spark plug may not be operating properly and should be replaced. Also check engine cylinder compression. With the engine not running, connect one end of a test probe to a good ground. Start the engine and run the other end of the test probe along the entire length of all spark plug cables. If cables are cracked or punctured, there will be a noticeable spark jump from the damaged area to the test probe. The cable running from the ignition coil to the distributor cap can be checked in the same manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket. Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped, remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable. Test all spark plug cables in this manner. SPARK PLUG CABLE RESISTANCE MINIMUM = MAXIMUM 250 Ohms Per Inch = 1000 Ohms Per Inch 3000 Ohms Per Foot = 12,000 Ohms Per Foot To test ignition coil-to-distributor cap cable, do not remove the cable from the cap. Connect ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace the cable. Inspect the ignition coil tower for cracks, burns or corrosion. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 891 Ignition Cable: Service and Repair REMOVAL AND INSTALLATION Cable Removal CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap, twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off with a steady, even force. Engine Firing Order Install cables into the proper engine cylinder firing order. When replacing the spark plug and coil cables, route the cables correctly and secure in the proper retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could also cause cross ignition of the plugs or short circuit the cables to ground. When installing new cables, make sure a positive connection is made. A snap should be felt when a good connection is made between the plug cable and the distributor cap tower. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Distributor, Ignition > Distributor Cap > Component Information > Testing and Inspection Distributor Cap: Testing and Inspection Cap Inspection - External - Typical Cap Inspection - Internal - Typical Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the inside (caused by condensation entering the cap through cracks) Replace any cap that displays charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence of mechanical interference with the rotor tip. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Distributor, Ignition > Ignition Rotor > Component Information > Testing and Inspection Ignition Rotor: Testing and Inspection Rotor Inspection - Typical Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip. Also check for evidence of mechanical interference with the cap. Some charring is normal on the end of the metal tip. The silicone-dielectric-varnish-compound applied to the rotor tip for radio interference noise suppression, will appear charred. This is normal. Do not remove the charred corn- pound. Test the spring for insufficient tension. Replace a rotor that displays any of these adverse conditions. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications Spark Plug: Specifications Electrode Gap ...................................................................................................................................... ..................................................... 1.01 mm (0.040 in) Torque ............................................................ ............................................................................................................................................. 41 Nm (30 ft. lb.) Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 902 Spark Plug: Application and ID Plug Type ............................................................................................................................................ ....................................................................

Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in which they were removed from the engine. A single plug displaying an abnormal condition indicates that a problem exists in the corresponding cylinder. Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or oil fouled. Refer to the Spark Plug Condition. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 904 Spark Plug: Testing and Inspection SPARK PLUG CONDITIONS Normal Operation And Cold (Carbon) Fouling NORMAL OPERATING The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is evident with most grades of commercial gasoline. There will not be evidence of electrode burning. Gap growth will not average more than approximately 0.025 mm (0.001 in) per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the electrodes filed, have the gap set and then be installed. Some fuel refiners in several areas of the United States have introduced a manganese additive (MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits. COLD FOULING/CARBON FOULING Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be caused by a clogged air cleaner element or repeated short operating times (short trips). WET FOULING OR GAS FOULING A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the fouled plugs. Oil Or Ash Encrusted OIL OR ASH ENCRUSTED Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 905 If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of oil entry into that particular combustion chamber. Electrode Gap Bridging ELECTRODE GAP BRIDGING Electrode gap bridging may be traced to loose deposits in the combustion chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be cleaned using standard procedures. Scavenger Deposits SCAVENGER DEPOSITS Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is a normal condition caused by chemical additives in certain fuels. These additives are designed to change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in condition and can be cleaned using standard procedures. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 906 Chipped Electrode Insulator CHIPPED ELECTRODE INSULATOR A chipped electrode insulator usually results from bending the center electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation can also separate the insulator from the center electrode. Spark plugs with this condition must be replaced. Preignition Damage PREIGNITION DAMAGE Preignition damage is usually caused by excessive combustion chamber temperature. The center electrode dissolves first and the ground electrode dissolves somewhat latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine. Determine if ignition timing is over advanced or if other operating conditions are causing engine overheating. (The heat range rating refers to the operating temperature of a particular type spark plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon the thickness and length of the center electrodes porcelain insulator.) Spark Plug Overheating SPARK PLUG OVERHEATING Overheating is indicated by a white or gray center electrode insulator that also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug overheating. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 907 Spark Plug: Service and Repair Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each cable boot and spark plug. If removal of the heat shield(s) is necessary,remove the spark plug cable and compress the sides of shield for removal. Each shield is slotted to allow for compression and removal. To install the shields, align shield to machined opening in cylinder head and tap into place with a block of wood. PLUG REMOVAL Cable Removal 1. Always remove spark plug or ignition coil cables by grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady motion. Never pull directly on the cable. Internal damage to cable will result. 2. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area around the spark plug. This will help prevent foreign material from entering the combustion chamber. 3. Remove the spark plug using a quality socket with a rubber or foam insert. 4. Inspect the spark plug condition. Refer to Spark Plug Condition in the Diagnostics and Testing. PLUG CLEANING The plugs may be cleaned using commercially available spark plug cleaning equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before adjusting gap. CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will remain on the spark plug insulator and will cause plug misfire. PLUG GAP ADJUSTMENT Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 908 Setting Spark Plug Gap - Typical Check the spark plug gap with a gap gauge tool. If the gap is not correct, adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center electrode. SPARK PLUG GAP 1.01 mm (0.040 in) PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged. Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator. When replacing the spark plug and ignition coil cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground. 1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark plugs to 35-41 N-m (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications Compression Check: Specifications Compression should not be less than 689 kPa (100 psi) and not vary more than 172 kPa (25 psi) from cylinder to cylinder. If cylinder(s) have abnormally low compression pressures, repeat procedure. - If the same cylinder(s) repeat an abnormally low reading, it could indicate the existence of a problem in the cylinder. NOTE: The recommended compression pressures are to be used only as a guide to diagnosing engine problems. An engine should NOT be disassembled to determine the cause of low compression unless some malfunction is present. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications > Page 912 Compression Check: Testing and Inspection The combustion pressure leakage test provides an accurate means for determining engine condition. Combustion pressure leakage testing will detect: ^ Exhaust and intake valve leaks (improper seating). ^ Leaks between adjacent cylinders or into water jacket. ^ Any causes for combustion/compression pressure loss. 1. Check the coolant level and fill as required. DO NOT install the radiator cap. 2. Start and operate the engine until it attains normal operating temperature, then turn the engine OFF. 3. Remove the spark plugs. 4. Remove the oil filler cap. 5. Remove the air cleaner. 6. Calibrate the tester according to the manufacturer's instructions. The shop air source for testing should maintain 483 kPa (70 psi) minimum, 1,379 kPa (200 psi) maximum and 552 kPa (80 psi) recommended. 7. Perform the test procedures on each cylinder according to the tester manufacturer's instructions. While testing, listen for pressurized air escaping through the throttle body, tailpipe and oil filler cap opening. Check for bubbles in the radiator coolant. All gauge pressure indications should be equal, with no more than 25% leakage. FOR EXAMPLE: At 552 kPa (80 psi) input pressure, a minimum of 414 kPa (60 psi) should be maintained in the cylinder.

High pressures are produced in the system when it is operating. Extreme care must be exercised to make sure that a]l refrigerant system connections are pressure tight. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. Sharp bends will reduce the flow of refrigerant. The flexible hose lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold. It is a good practice to inspect all flexible refrigerant system hose lines at least once a year to make sure they are in good condition and properly routed. There are two types of refrigerant fittings: All fittings with O-rings need to be coated with refrigerant oil before installation. Use only O-rings that are the correct size and approved for use with R-134a refrigerant. Failure to do so may result in a leak. - Unified plumbing connections with gaskets cannot be serviced with O-rings. The gaskets are not reusable and new gaskets do not require lubrication before installing. Using the proper tools when making a refrigerant plumbing connection is very important. Improper tools or improper use of the tools can damage the refrigerant fittings. The refrigerant must be recovered completely from the system before opening any fitting or connection. Open the fittings with caution, even after the refrigerant has been recovered. If any pressure is noticed as a fitting is loosened, tighten the fitting and recover the refrigerant from the system again. Do not discharge refrigerant into the atmosphere. Use an R. 134a refrigerant recovery/recycling device that meets SAE Standard J2210. The refrigerant system will remain chemically stable as long as pure, moisture-free R-134a refrigerant and refrigerant oil is used. Dirt, moisture, or air can upset this chemical stability Operational troubles or serious damage can occur if foreign material is present in the refrigerant system. When it is necessary to open the refrigerant system, have everything needed to service the system ready. The refrigerant system should not be left open to the atmosphere any longer than necessary. Cap or plug all lines and fittings as soon as they are opened to prevent the entrance of dirt and moisture. All lines and components in parts stock should be capped or sealed until they are to be installed. All tools, including the refrigerant recycling equipment, the manifold gauge set, and test hoses should be kept clean and dry All tools and equipment must be designed for R-134a refrigerant. SYSTEM OPERATION Refrigerant Lines The refrigerant lines and hoses are used to carry the refrigerant between the various air conditioning system components. A barrier hose design with a nylon tube inner hose liner is used for the R-134a air conditioning system on this vehicle. This nylon liner helps to further contain the R-134a refrigerant, which has a smaller molecular structure than R-12 refrigerant. The ends of the refrigerant hoses are made from lightweight aluminium or steel, and use braze-less fittings. Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system. Kinks and sharp bends reduce the flow of refrigerant in the system. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold. High pressures are produced in the refrigerant system when the air conditioning compressor is operating. Extreme care must be exercised to make sure that each of the refrigerant system connections is pressure-tight and leak free. It is a good practice to inspect all flexible hose refrigerant lines at least once a year to make sure they are in good condition and properly routed. The refrigerant lines and hoses are coupled with other components of the HVAC system with peanut- block style fittings. A status seal type flat steel gasket with a captured compressible O-ring, is used to mate plumbing lines with A/C components to ensure the integrity of the refrigerant system. The refrigerant lines and hoses cannot be repaired and, if faulty or damaged, they must be replaced. Low Pressure Gauge Hose The low pressure hose (Blue with Black stripe) attaches to the suction service port. This port is located on the compressor manifold, directly over the suction port of the compressor. High Pressure Gauge Hose The high pressure hose (Red with Black stripe) attaches to the discharge service port. This port is located on the liquid line between the condenser and the evaporator, near the front of the engine compartment. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Hoses > Hose/Line HVAC > Component Information > Locations > Page 967 Recovery/Recycling/Evacuation/Charging Hose The center manifold hose (Yellow, or White, with Black stripe) is used to recover, evacuate, and charge the refrigerant system. When the low or high pressure valves on the manifold gauge set are opened, the refrigerant in the system will escape through this hose. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Hoses > Hose/Line HVAC > Component Information > Service and Repair > A/C Discharge Hose/Line Replacement Hose/Line HVAC: Service and Repair A/C Discharge Hose/Line Replacement Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system.

In case of contact, take the following actions: * Eye Contact-rinse eyes thoroughly with water. * Skin Contact-wash skin with soap and water. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Brake Fluid > Component Information > Specifications > Page 980 Brake Fluid: Testing and Inspection CAUTION: The hydraulic fluid used in automotive brake systems is hygroscopic. This means that the hydraulic fluid tends to absorb moisture from the atmosphere over periods of time. As hydraulic brake fluid absorbs moisture, it effects the function of the vehicles hydraulic brake system. For this reason, the vehicle's hydraulic brake fluid should be drained and replaced using fresh clean hydraulic brake fluid every two years. When replacing hydraulic brake fluid, use only Mopar brake fluid or an equivalent from a sealed container. Brake fluid must conform to DOT 3 specifications. BRAKE FLUID CONTAMINATION Indications of fluid contamination are swollen or deteriorated rubber parts. Swelling indicates the presence of petroleum in the brake fluid. To test for contamination, put a small amount of drained brake fluid in clear glass jar. If the fluid separates into layers, there is mineral oil or other fluid contamination of the brake fluid. If the brake fluid is contaminated, drain and thoroughly flush the brake system. Replace all the rubber parts or components containing rubber coming into contact with the brake fluid. This includes the master cylinder, proportioning valves, caliper seals, wheel cylinder seals, ABS hydraulic control unit (HCU), and all hydraulic fluid hoses. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Brake Fluid > Component Information > Specifications > Page 981 Brake Fluid: Service and Repair BRAKE FLUID LEVEL Always clean the master cylinder reservoir and caps before checking fluid level.

The recommended mixture of 50/50 ethylene-glycol and water will provide protection against freezing to -37° C (-35° F). The antifreeze concentration must always be a minimum of 44%, year round, in all climates. If percentage is lower than 44%, engine parts may be eroded by cavitation, and cooling system components may be severely damaged by corrosion. Maximum protection against freezing is provided with a 68% antifreeze concentration, which prevents freezing down to -67.7° C (-90° F). A higher percentage will freeze at a warmer temperature. Also, a higher percentage of antifreeze can cause the engine to overheat because the specific heat of antifreeze is lower than that of water. 100 Percent Ethylene-Glycol Should Not Be Used Use of 100 Percent Ethylene-Glycol will cause formation of additive deposits in the system, as the corrosive inhibitive additives in ethylene-glycol require the presence of water to dissolve. The deposits act as insulation, causing temperatures to rise as high as 149° C (300° F). this temperature is hot enough to melt plastic and soften solder. The increased temperature can result in engine detonation. In addition, 100 % ethylene-glycol freezes at 22° C (-8° F). Propylene-Glycol Formulations Should Not Be Used Propylene-glycol formulations do not meet the required specifications. It's overall effective temperature range is smaller than that of ethylene-glycol. The freeze point of 50/50 propylene-glycol and water is -32° C (-26° F), 5 degrees higher than ethylene-glycol's freeze point. The boiling point (protection against summer boil-over) of propylene-glycol is 125° C (257° F) at 96.5 kPa (14 PSI), compared to 128° C (263° F) for ethylene-glycol. Use of propylene-glycol can result in boil-over and freeze up. Propylene-Glycol also has a poorer heat transfer characteristics than ethylene-glycol. This can increase cylinder head temperatures under certain conditions. Propylene-Glycol/Ethylene-Glycol Mixtures Should Not Be Used Propylene-glycol/ethylene-glycol mixtures can cause the destabilization of various corrosion inhibitors, causing damage to the coling system components. Also, once ethylene-glycol and propylene-glycol based coolants are mixed in the vehicle, conventional methods of determining the freeze point will not be accurate. Both the refractive index and specific gravity differ between the ethylene-glycol and propylene-glycol. CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can cause problems associated with 100 percent ethylene-glycol. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Coolant > Component Information > Specifications > Page 987 Coolant: Service Precautions DO NOT mix green colored coolant with orange colored coolant. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Coolant > Component Information > Description and Operation > Ethylene-Glycol Mixtures Coolant: Description and Operation Ethylene-Glycol Mixtures The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle operating conditions.

DISCUSSION: The axle lubricant used in all corporate axles was changed in formulation starting at the beginning of the 1998 model year. The corporate axles involved include: the 8.25 and 9.25 rear axles, and the C205F front axle. The new lubricant in use is SAE 75W-90 p/n 05010320AA. The lubricant change was made as a fuel economy improvement. The new axle lubricant is more chemically aggressive/reactive when in contact with the previous used Room Temperature Vulcanizable (RTV) sealant. Because of this condition, the RTV used in assembly of the pan/cover to the axle housing was revised and improved. When re-sealing axle covers, using the proper sealing material to minimize any potential sealant breakdown is important. The only recommended sealing material for all corporate axle covers is MOPAR RTV Sealant, p/n 05013477M. This RTV is red/orange in color. NOTE: IF SAE 75W-90 LUBRICANT IS USED TO REFILL ANY CORPORATE AXLE, THEN THE RED/ORANGE MOPAR RTV SEALANT, P/N 05013477AA, SHOULD BE USED TO SEAL THE COVER TO THE AXLE HOUSING. To optimize sealant performance and enhance adhesion, flanges should be clean and free of residual lubricant. The mating flanges should first be cleaned of any excess old RTV using a plastic putty knife. Final cleaning/degreasing shall be done by spraying MOPAR Brake Parts Cleaner, p/n 04549623, on the carrier and cover flanges, followed by a wipe with a clean dry cloth. Care should be taken to avoid spraying the parts cleaner inside the carrier. Once the RTV has been applied, the axle cover is to be installed to the housing within 3 to 5 minutes to prevent skinning over of the RTV. NOTE: IF THE AXLE COVER IS NOT INSTALLED WITHIN THE 3 TO 5 MINUTE TIME FRAME, THE CARRIER COVER FACE MUST BE RECLEANED AND NEW RTV APPLIED, OR ADHESION QUALITY WILL BE COMPROMISED. Immediately install the cover attaching bolts and tighten them to the specified torque to prevent a shimming effect by the RTV.

DISCUSSION: The customer or servicing technician may notice a milky-like appearance to the 9.25 inch rear axle fluid. This condition may be brought to the customer's attention when the axle fluid is inspected during normal service. Other than the concern for the color of axle fluid, the customer does not experience any other axle complaint. The customer or servicing technician may be concerned because a milky-like appearance to the axle fluid may also indicate the presence of water. The cause of the milky-like appearance to the axle fluid may be due to the use of a white color gear marking compound during the axle assembly process. Axle gear marking compound is used to verify correct ring and pinion gear alignment during manufacture. The 9.25 inch rear axle is assembled on two different assembly lines. To visually distinguish axles from each assembly line, one assembly line used a white color gear marking compound (versus yellow). Half of the axles that were assembled during the above time frame may have the white gear marking compound mixed with the rear axle fluid. The white color gear marking compound is no longer in use by the axle assembly plant. NOTE: IF THE MILKY-LIKE REAR AXLE FLUID APPEARANCE IS DUE TO THE WHITE GEAR MARKING COMPOUND, THEN NO SERVICE ACTION IS NECESSARY TO ADDRESS THIS CONDITION. If the milky-like rear axle fluid appearance is due to the presence of water, then the rear axle will require service. Axle fluid, contaminated with water, may cause rust and damage to the internal components of the axle. Any water in the axle fluid will begin to boil off (reach its gaseous state) before the oil. Placing a small sample of axle fluid on a hot steel surface (around 100C or 212F) will cause any water that may be present in the fluid to boil off with a "sizzle-like" sound.

Raise and support the vehicle. 2. Remove the lubricant fill hole plug from the differential housing cover. 3. Remove the differential housing cover and drain the lubricant from the housing. 4. Clean the housing cavity with a flushing oil, light engine oil, or lint free cloth. Do not use water, steam, kerosene, or gasoline for cleaning. 5. Remove the original sealant from the housing and cover surfaces. Fig. 8 6. Apply a bead of MOPAR Silicone Rubber Sealant, or equivalent, to the housing cover. Install the housing cover within 6 minutes after applying the sealant. 7. Install the cover and any identification tag. Tighten the cover bolts to 41 Nm (30 ft. lbs.) torque. 8. For Trac-lok differentials, a quantity of MOPAR Trac-lok lubricant (friction modifier), or equivalent, must be added after repair service or a lubricant change. 9. Fill differential with MOPAR Hypoid Gear Lubricant, or equivalent, to bottom of the fill plug hole. CAUTION: Overfilling the differential can result in lubricant foaming and overheating. 10. Install the fill hole plug and lower the vehicle. 11. Trac-lok differential equipped vehicles should be road tested by making 10 to 12 slow figure-eight turns. This maneuver will pump the lubricant through the clutch discs to eliminate a possible chatter noise complaint. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Fluid - Transfer Case > Component Information > Specifications > NV231 Transfer Case Fluid - Transfer Case: Specifications NV231 Transfer Case Transfer Case ...................................................................................................................................... ......................................................... 1.2L (2.5 Pints) Correct fill level is to the bottom edge of the fill plug hole. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Fluid - Transfer Case > Component Information > Specifications > NV231 Transfer Case > Page 1022 Fluid - Transfer Case: Specifications NV242 Transfer Case Transfer Case ...................................................................................................................................... ....................................................... 1.3L (2.8 Pints) Correct fill level is to the bottom edge of the fill plug hole. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Fluid - Transfer Case > Component Information > Specifications > Page 1023 Fluid - Transfer Case: Service Precautions DO NOT over fill transfer case beyond normal fluid level.

ENGINE OIL SPECIFICATION CAUTION: Do not use non-detergent or straight mineral oil when adding or changing crankcase lubricant. Engine failure can result. API SERVICE GRADE CERTIFIED Engine Oil Container Standard Notations In gasoline engines, use an engine oil that is API Service Grade Certified. Standard engine oil identification notations have been adopted to aid in the proper selection of engine oil. The identifying notations are located on the label of engine oil plastic bottles and the top of engine oil cans. MOPAR(R) only provides engine oil that conforms to this certification. SAE VISCOSITY Temperature/Engine Oil Viscosity Recommendation An SAE viscosity grade is used to specify the viscosity of engine oil. SAE 1OW-30 specifies a multiple viscosity engine oil. These are specified with a dual SAE viscosity grade which indicates the cold-to-hot temperature viscosity range. When choosing an engine oil, consider the range of temperatures the vehicle will be operated in before the next oil change. Select an engine oil that is best suited to your area's particular ambient temperature range and variation. ENERGY CONSERVING OIL An Energy Conserving type oil is recommended for gasoline engines. The designation of ENERGY CONSERVING is located on the label of an engine oil container. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Engine Oil > Component Information > Service Precautions > Page 1033 Engine Oil: Testing and Inspection CRANKCASE OIL LEVEL INSPECTION CAUTION: Do not overfill crankcase with engine oil, oil foaming and oil pressure loss can result. To ensure proper lubrication of an engine, the engine oil must be maintained at an acceptable level. The acceptable levels are indicated between the ADD and SAFE marks on the engine oil dipstick. 1. Position vehicle on level surface. 2. With engine OFF, allow approximately ten minutes for oil to settle to bottom of crankcase, remove engine oil dipstick. 3. Wipe dipstick clean. 4.

WJ/WG and ZH vehicles use unique power steering fluids. Refer to the table to identify factory fill and the approved service power steering fluid by year and model. Note that MS9602 is Red in color and MS5931 and MS9933 are Amber/Yellow in color. All three fluids will darken in color with usage and fluid color is no longer an indication of fluid condition. The part numbers for MS9602 are 05013457AA (quart) and 05013458AA (gallon). The part number for MS5931 is 04883077 (quart). The part number for MB345 is 05127381AA. MS9602 should not be mixed or used as a "topping off" fluid on systems requiring MS5931. On some past models, MS9602 should be used as the replacement fluid. On these models, if a power steering system is being serviced that results in a large fluid loss, such as a pump, hose or gear/rack replacement, the complete system should be drained and filled with MS9602. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Power Steering Fluid > Component Information > Technical Service Bulletins > Steering - Power Steering Fluid Usage > Page 1040 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fluids > Power Steering Fluid > Component Information > Technical Service Bulletins > Steering - Power Steering Fluid Usage > Page 1041 NOTE: This bulletin supersedes owner's and service manuals for the vehicles listed above that may state to use MS9933 in the power steering system, and that may state not to use automatic transmission fluid in the power steering system.

After the refrigerant system has been charged and operated, the refrigerant oil in the compressor is dispersed throughout the refrigerant system. The accumulator, evaporator, condenser, and compressor will each retain a significant amount of the needed refrigerant oil. It is important to have the correct amount of oil in the refrigerant system. This ensures proper lubrication of the compressor. Too little oil will result in damage to the compressor. Too much oil will reduce the cooling capacity of the air conditioning system. It will not be necessary to check the oil level in the compressor or to add oil, unless there has been an oil loss. An oil loss may occur due to a rupture or leak from a refrigerant line, a connector fitting, a component, or a component seal. if a leak occurs, add 30 milliliters (1 fluid ounce) of refrigerant oil to the refrigerant system after the repair has been made. Refrigerant oil loss will be evident at the leak point by the presence of a wet, shiny surface around the leak. Refrigerant Oil Capacities Chart Refrigerant oil must be added when a accumulator, evaporator coil, or condenser are replaced. See the Refrigerant Oil Capacities chart. When a compressor is replaced, the refrigerant oil must be drained from the old compressor and measured. Drain all of the refrigerant oil from the new compressor, then fill the new compressor with the same amount of refrigerant oil that was drained out of the old compressor. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures Brake Bleeding: Service and Repair Antilock Brake System Bleeding Procedures W/ Four Wheel Antilock Brakes ABS system bleeding requires conventional bleeding methods plus use of the DRB scan tool. The procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to remove any air remaining in the system. 1. Perform base brake bleeding. 2. Connect scan tool to the Data Link Connector. 3. Select ANTILOCK BRAKES, followed by MISCELLANEOUS, then BLEED BRAKES. Follow the instructions displayed. When scan tool displays TEST COMPLETE, disconnect scan tool and proceed. 4. Perform base brake bleeding a second time. 5. Top off master cylinder fluid level and verify proper brake operation before moving vehicle. W/ Rear Wheel Antilock Brakes Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only. Use fresh, clean fluid from a sealed container at all times. Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into small bubbles that are distributed throughout the hydraulic system. This will make additional bleeding operations necessary. Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow additional air to be drawn into the system. Check the cylinder fluid level frequently and add fluid as needed.

Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially filled with brake fluid. Be sure end of bleed hose is immersed in fluid. 4. Open up bleeder, then have a helper press down the brake pedal. Once the pedal is down close the bleeder. Repeat bleeding until fluid stream is clear and free of bubbles. Then move to the next wheel. PRESSURE BLEEDING Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the tank manufacturers pressure recommendations. Generally, a tank pressure of 15-20 psi is sufficient for bleeding. Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding. Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to leakage, or drawing air back into the system. Use the adapter provided with the equipment or Adapter 6921. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures > Page 1062 Brake Bleeding: Service and Repair Base Brake System Bleeding Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only. Use fresh, clean fluid from a sealed container at all times. Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into small bubbles that are distributed throughout the hydraulic system. This will make additional bleeding operations necessary. Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow additional air to be drawn into the system. Check the cylinder fluid level frequently and add fluid as needed.

The PADS is equipped with a key cylinder so that the switch position can only be changed using an ignition key. When the ignition switch is in the On position and the passenger side airbag is disarmed, a Light-Emitting Diode (LED) illuminates an "Off" indicator lamp on the face plate of the switch. To actuate the PADS switch, insert the ignition key in the switch key cylinder. The PADS key cylinder is then rotated with the ignition key to its clockwise stop (the key cylinder slot will be aligned with the Off indicator lamp) to disarm the passenger side airbag. When the PADS key cylinder is rotated with the ignition key to its counterclockwise stop (the key cylinder slot will be in a vertical position), the Off indicator lamp will be extinguished and the passenger side airbag module will once again be armed. WARNING: THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG DISARM SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE PADS KEY CYLINDER. The PADS cannot be adjusted or repaired and, if faulty or damaged, the PADS unit must be replaced. Disarming Both Airbags Disconnect and isolate the battery negative cable. If the airbag has not been deployed, wait two minutes for the system capacitor to discharge before further service. Arming Both Airbags Prior to arming the system verify system operation as follows: A DRB scan tool is required for diagnosis of the airbag system. Refer to the proper Diagnostic Procedures for more information. 16-Way Data Link Connector - Typical 1. Connect the DRB scan tool to the 16-way data link wire harness connector. The connector is located on the driver side lower edge of the instrument panel, outboard of the steering column. 2. Turn the ignition switch to the On position. Exit the vehicle with the DRE. Use the latest version of the proper DRB cartridge. 3.. Using the DRB, read and record the active Diagnostic Trouble Code (DTC) data. 4. Read and record any stored DTC data. 5. Refer to the proper Diagnostic Procedures if any DTC is found in Step 3 or Step 4. 6. Erase the stored DTC data. If any problems remain, the stored DTC data will not erase. 7. With the ignition switch still in the ON position, make sure nobody is in the vehicle. 8. From outside of the vehicle (away from the airbag modules in case of an accidental deployment) turn the ignition switch to the OFF position for about ten seconds, and then back to the ON position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds, and then go out. This indicates that the airbag system is functioning normally NOTE: It the airbag indicator lamp fails to light, or lights and stays on, there is an airbag system malfunction. Refer to the proper Diagnostic Procedures to diagnose the problem. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Circuit Breaker > Component Information > Locations Circuit Breaker: Locations 8w-12-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Circuit Breaker > Component Information > Locations > Page 1070 8w-12-3 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Circuit Breaker > Component Information > Locations > Page 1071 Circuit Breaker: Diagrams 8w-12-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Circuit Breaker > Component Information > Locations > Page 1072 8w-12-3 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Circuit Breaker > Component Information > Locations > Page 1073 8w-12-5 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Circuit Breaker > Component Information > Locations > Page 1074 Circuit Breaker: Description and Operation SYSTEM OPERATION An automatic resetting circuit breaker in the junction block is used to protect the power seat system circuit. The circuit breaker can protect the system from a short circuit, or from an overload condition caused by an obstructed or stuck seat adjuster. The circuit breaker cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Circuit Breaker > Component Information > Locations > Page 1075 Circuit Breaker: Testing and Inspection 1. Locate the correct circuit breaker in the junction block. Pull out the circuit breaker slightly, but be certain that the circuit breaker terminals still contact the terminals in the junction block cavities. 2. Connect the negative lead of a 12-volt DC voltmeter to a good ground. 3. With the voltmeter positive lead, check both terminals of the circuit breaker for battery voltage. If only one terminal has battery voltage, the circuit breaker is faulty and must be replaced. If neither terminal has battery voltage, repair the open circuit from the Power Distribution Center (PDC) as required. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse > Component Information > Technical Service Bulletins > DTC's - Caused By Open Fuses Fuse: Technical Service Bulletins DTC's - Caused By Open Fuses NUMBER: 18-09-99 GROUP: Vehicle Performance DATE: May 21, 1999 SUBJECT: Common Diagnostic Trouble Codes Caused By An Open Fuse. MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango 1999 (TJ) Wrangler 1999 (WJ) Grand Cherokee 1999 (XJ) Cherokee DISCUSSION: Recent quality analysis has revealed an issue with repeated repairs for the same Diagnostic Trouble Code (DTC). The DTC may be due to an overlooked open circuit used to power the component in question. In most instances, either the circuit fuse has been erroneously removed or the fuse itself has an open (blown). The component in question, and its circuit, are often protected by two fuses. It is usually the lower amperage fuse that is either missing or open. The lower amperage fuse is positioned electrically in the circuit between the component in question and either a relay (Auto Shut Down, 02 heater) or the ignition switch. The lower amperage fuse will be located either in the underhood Power Distribution Center (PDC) or in the instrument panel Junction Block. The lower amperage fuse is often missing because it was removed erroneously for use in another low current circuit. If the lower amperage fuse is open (blown), then the circuit and component in question must be checked for an electrical short. Check to make sure that the open fuse was not exchanged with another fuse or was damaged by an installed accessory. NOTE: IF AN OXYGEN SENSOR IS REPLACED, VERIFY THAT THE CIRCUIT FUSE IS GOOD. AN OXYGEN SENSOR HEATER, WHEN DAMAGED OR OVERHEATED, MAY SHORT THE CIRCUIT AND CAUSE THE FUSE TO OPEN (BLOW). The higher amperage fuse should be checked, but is not normally the cause of the DTC. The higher amperage fuse is located in the underhood PDC. It is positioned electrically in the circuit between the battery and either the relay (Auto Shut Down, 02 heater) or the ignition switch. Refer to the applicable Diagnostic Procedures Manual and/or Service Manual (Group 8) for further technical assistance. The following is a list of the components frequently replaced erroneously due to an open fuse. Included are the possible DTC(s) which would be generated as a result. 1).

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1088 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1089 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1090 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1091 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1092 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1093 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1103 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 1104 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information

The molded plastic JB housing has integral mounting brackets that are secured with two screws to the left instrument panel end bracket. The left end of the instrument panel cover has a snap-fit fuse access panel that can be removed for service of the junction block fuses. A fuse puller and spare fuse holders are located on the back of the fuse access cover, as well as an adhesive-backed fuse layout label to ensure proper fuse identification. The JB combines the functions previously provided by a separate fuseblock module and relay center, serves to simplify and centralize numerous electrical components, and to distribute electrical current to many of the accessory systems in the vehicle. It also eliminates the need for numerous splice connections and serves in place of a bulkhead connector between many of the engine compartment, instrument panel, and body wire harnesses. All of the circuits entering and leaving the JB do so through up to nine wire harness connectors, which are connected to the JB. through integral connector receptacles molded into the JB housing. The JB houses up to nineteen blade-type fuses (two standard-type and seventeen mini-type), up to two blade- type automatic resetting circuit breakers, the electronic combination turn signal and hazard warning flasher, and one International Standards Organization (ISO) micro-relay Internal connection of all of the JB circuits is accomplished by an intricate combination of hard wiring and bus bars. The fuses, circuit breakers, relays and flasher are available for service replacement. The JB unit cannot be repaired and is only serviced as an assembly. If any internal circuit or if the JB housing is faulty or damaged, the entire JB unit must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information > Diagrams > Page 1131 Fuse Block: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The original tire should be repaired or replaced at the first opportunity and reinstall. Do not exceed speeds of 50 MPH. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Description and Operation Wheels: Description and Operation The rim size is on the vehicle safety certification label located on the drivers door shut face. The size of the rim is determined by the drivetrain package. Original equipment wheels/rims are designed for operation up to the specified maximum vehicle capacity. Fig. 1 All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised sections between the rim flanges and rim drop well called safety humps. Initial inflation of the tire forces the bead over these raised sections. In case of rapid loss of air pressure, the raised sections help hold the tire on the wheel. The wheel studs and nuts are designed for specific applications. All aluminum and some steel wheels have wheel stud nuts with an enlarged nose. This enlarged nose is necessary to ensure proper retention of the wheels. Do not use replacement studs or nuts with a different design or lesser quality. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Maintenance > Wheels and Tires > Wheels > Component Information > Description and Operation > Page 1152 Wheels: Testing and Inspection Inspect wheels for: Excessive run out - Dents or cracks - Damaged wheel lug nut holes - Air Leaks from any area or surface of the rim NOTE: Do not attempt to repair a wheel by hammering, heating or welding. If a wheel is damaged an original equipment replacement wheel should be used. When obtaining replacement wheels, they should be equivalent in load carrying capacity. The diameter, width, offset, pilot hole and bolt circle of the wheel should be the same as the original wheel. WARNING: FAILURE TO USE EQUIVALENT REPLACEMENT WHEELS MAY ADVERSELY AFFECT THE SAFETY AND HANDLING OF THE VEHICLE. USED WHEELS ARE NOT RECOMMENDED.

If cylinder(s) have abnormally low compression pressures, repeat procedure. - If the same cylinder(s) repeat an abnormally low reading, it could indicate the existence of a problem in the cylinder. NOTE: The recommended compression pressures are to be used only as a guide to diagnosing engine problems. An engine should NOT be disassembled to determine the cause of low compression unless some malfunction is present. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Compression Check > System Information > Specifications > Page 1180 Compression Check: Testing and Inspection The combustion pressure leakage test provides an accurate means for determining engine condition. Combustion pressure leakage testing will detect: ^ Exhaust and intake valve leaks (improper seating). ^ Leaks between adjacent cylinders or into water jacket. ^ Any causes for combustion/compression pressure loss. 1. Check the coolant level and fill as required. DO NOT install the radiator cap. 2. Start and operate the engine until it attains normal operating temperature, then turn the engine OFF. 3. Remove the spark plugs. 4. Remove the oil filler cap. 5. Remove the air cleaner. 6. Calibrate the tester according to the manufacturer's instructions. The shop air source for testing should maintain 483 kPa (70 psi) minimum, 1,379 kPa (200 psi) maximum and 552 kPa (80 psi) recommended. 7. Perform the test procedures on each cylinder according to the tester manufacturer's instructions. While testing, listen for pressurized air escaping through the throttle body, tailpipe and oil filler cap opening. Check for bubbles in the radiator coolant. All gauge pressure indications should be equal, with no more than 25% leakage. FOR EXAMPLE: At 552 kPa (80 psi) input pressure, a minimum of 414 kPa (60 psi) should be maintained in the cylinder.

If vehicle has no oil pressure gauge, install a reliable gauge at the pressure sending-unit. The pressure should be between 207 - 552 kPa (30 - 80 psi) at 3,000 RPM. Check the oil level after the engine reaches normal operating temperature. Allow 5 minutes to stabilize oil level, check dipstick. The oil level in the pan should never be above the FULL mark or below the ADD OIL mark on dipstick. Either of these two conditions could be responsible for noisy tappets. OIL LEVEL HIGH If oil level is above the FULL mark, it is possible for the connecting rods to dip into the oil. With the engine running, this condition could create foam in the oil pan. Foam in oil pan would be fed to the hydraulic tappets by the oil pump causing them to lose length and allow valves to seat noisily. LOW Low oil level may allow oil pump to take in air. When air is fed to the tappets, they lose length, which allows valves to seat noisily. Any leaks on intake side of oil pump through which air can be drawn will create the same tappet action. Check the lubrication system from the intake strainer to the pump cover, including the relief valve retainer cap. When tappet noise is due to aeration, it may be intermittent or constant, and usually more than one tappet will be noisy. When oil level and leaks have been corrected, operate the engine at fast idle. Run engine for a sufficient time to allow all of the air inside the tappets to be bled out. TAPPET NOISE DIAGNOSIS 1. To determine source of tappet noise, operate engine at idle with cylinder head covers removed. 2. Feel each valve spring or rocker arm to detect noisy tappet. The noisy tappet will cause the affected spring and/or rocker arm to vibrate or feel rough in operation. NOTE: Worn valve guides or cocked springs are sometimes mistaken for noisy tappets. If such is the case, noise may be dampened by applying side thrust on the valve spring. If noise is not appreciably reduced, it can be assumed the noise is in the tappet. Inspect the rocker arm push rod sockets and push rod ends for wear. 3. Valve tappet noise ranges from light noise to a heavy click. A light noise is usually caused by excessive leak-down around the unit plunger, or by the plunger partially sticking in the tappet body cylinder. The tappet should be replaced. A heavy click is caused by a tappet check valve not seating, or by foreign particles wedged between the plunger and the tappet body. This will cause the plunger to stick in the down position. This heavy click will be accompanied by excessive clearance between the valve stem and rocker arm as valve closes. In either case, tappet assembly should be removed for inspection and cleaning. 4. The valve train generates a noise very much like a light tappet noise during normal operation. Care must be taken to ensure that tappets are making the noise. If more than one tappet seems to be noisy, it's probably not the tappets. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Camshaft, Lifters and Push Rods > Lifter / Lash Adjuster, Valve > Component Information > Service and Repair > Removal and Installation Lifter / Lash Adjuster: Service and Repair Removal and Installation REMOVAL 1.

This allows for expansion under normal operating conditions. Under operating temperatures, expansion forces the pin bosses away from each other, causing the piston to assume a more nearly round shape. All pistons are machined to the same weight, regardless of size, to maintain piston balance. The piston pin rotates in the piston only and is retained by the press interference fit of the piston pin in the connecting rod. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Block Assembly > Piston, Engine > Component Information > Service and Repair > Removal and Installation Piston: Service and Repair Removal and Installation PISTON AND CONNECTING ROD ASSEMBLY REMOVAL 1.

Remove the cylinder head. 2. Compress valve springs using Valve Spring Compressor Tool MD-998772A. 3. Remove valve retaining locks, valve spring retainers, valve stem seals and valve springs. 4. Before removing valves, remove any burrs from valve stem lock grooves to prevent damage to the valve guides. Identify valves to ensure installation in original location. INSTALLATION 1. Coat valve stems with lubrication oil and insert them in cylinder head. 2. If valves or seats are reground, check valve stem height. If valve is too long, replace cylinder head. 3. Install new seals on all valve guides. Install valve springs and valve retainers. 4. Compress valve springs with Valve Spring Compressor Tool MD-998772A, install locks and release tool. If valves and/or seats are ground, measure the installed height of springs. Make sure the measurement is taken from bottom of spring seat in cylinder head to the bottom surface of spring retainer. If spacers are installed, measure from the top of spacer. If height is greater than 42.86 mm (1-11/16 inches), install a 1.587 mm (1/16 inch) spacer in head counterbore. This should bring spring height back to normal 41.27 to 42.86 mm (1-5/8 to 1-11/16 inch). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Head Assembly > Valve, Intake/Exhaust > Component Information > Service and Repair > Removal and Installation > Page 1311 Valve: Service and Repair Valve Service VALVE CLEANING Clean valves thoroughly. Discard burned, warped and cracked valves. Remove carbon and varnish deposits from inside of valve guides with a reliable guide cleaner. VALVE INSPECTION Measure valve stems for wear. If wear exceeds 0.051 mm (0.002 inch), replace the valve. VALVE GUIDES Measure valve stem guide clearance as follows: Positioning Valve With Tool C-3973 1. Install Valve Guide Sleeve Tool C-3973 over valve stem and install valve. The special sleeve places the valve at the correct height for checking with a dial indicator. Measuring Valve Guide Wear 2. Attach Dial Indicator Tool C-3339 to cylinder head and set it at right angle of valve stem being measured. Reamer Sizes 3. Move valve to and from the indicator. The total dial indicator reading should not exceed 0.432 mm (0.017 inch). Ream the guides for valves with oversize stems if dial indicator reading is excessive or if the stems are scuffed or scored. Service valves with oversize stems are available. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Head Assembly > Valve, Intake/Exhaust > Component Information > Service and Repair > Removal and Installation > Page 1312 Slowly turn reamer by hand and clean guide thoroughly before installing new valve. Ream the valve guides from standard to 0.381 mm (0.015 inch). Use a 2 step procedure so the valve guides are reamed true in relation to the valve seat: ^ Step 1-Ream to 0.0763 mm (0.003 inch). ^ Step 2-Ream to 0.381 mm (0.015 inch). REFACING VALVES AND VALVE SEATS Valve Face And Seat Angles The intake and exhaust valves have a 43-1/4° to 43-3/4° face angle and a 44-1/4° to 44-3/4° seat angle. VALVES Intake And Exhaust Valves Inspect the remaining margin after the valves are refaced. Valves with less than 1.190 mm (0.047 inch) margin should be discarded. VALVE SEATS Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Head Assembly > Valve, Intake/Exhaust > Component Information > Service and Repair > Removal and Installation > Page 1313 Refacing Valve Seats CAUTION: DO NOT un-shroud valves during valve seat refacing. 1. When refacing valve seats, it is important that the correct size valve guide pilot be used for reseating stones. A true and complete surface must be obtained. 2. Measure the concentricity of valve seat using a dial indicator. Total runout should not exceed 0.051 mm (0.002 inch) total indicator reading. 3. Inspect the valve seat with Prussian blue to determine where the valve contacts the seat. To do this, coat valve seat LIGHTLY with Prussian blue then set valve in place. Rotate the valve with light pressure. If the blue is transferred to the center of valve face, contact is satisfactory. If the blue is transferred to the top edge of valve face, lower valve seat with a 15° stone. If the blue is transferred to bottom edge of valve face raise valve seat with a 60° stone. 4. When seat is properly positioned the width of intake seats should be 1.016 - 1.524 mm (0.040 0.060 inch). The width of the exhaust seats should be 1.524 - 2.032 mm (0.060 - 0.080 inch). VALVE SPRING INSPECTION Testing Valve Spring For Compressed Length Whenever valves have been removed for inspection, reconditioning or replacement, valve springs should be tested. As an example the compression length of the spring to be tested is 1-5/16 inch. Turn table of Universal Valve Spring Tester Tool until surface is in line with the 1-5/16 inch mark on the threaded stud. Be sure the zero mark is to the front. Place spring over stud on the table and lift compressing lever to set tone device. Pull on torque wrench until ping is heard. Take reading on torque wrench at this instant. Multiply this reading by 2. This will give the spring load at test length. Fractional measurements are indicated on the table for finer adjustments. Refer to specifications to obtain specified height and allowable tensions. Discard the springs that do not meet specifications. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Diagrams Belt Routing -3.9l?5.2L/5.9L Engine Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Drive Belts, Mounts, Brackets and Accessories > Drive Belt > Component Information > Diagrams > Page 1318 Drive Belt: Description and Operation Belt tension is adjusted at the power steering pump bracket and idler pulley assembly.

THIS IS A COMPLETE REVISION AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS. SUBJECT: Spark Knock And Engine Oil Consumption Due To Intake Manifold Pan Gasket Oil Leak OVER VIEW: This bulletin involves the replacement of the engine intake manifold plenum pan gasket. NOTE: THIS BULLETIN APPLIES TO VEHICLE EQUIPPED WITH A 3.9L, 5.2L. OR 5.9L GASOLINE ENGINE. SYMPTOM/CONDITION: An engine intake manifold plenum pan gasket oil leak may occur on some V-6 and V-8 style engines. The oil leak is internal to the engine so no external oil leakage will be present. Two symptoms of this oil leak condition may be present. The vehicle operator may experience an engine spark knock during acceleration and/or an increase in the amount of engine oil consumed by the engine. DIAGNOSIS: Make sure Technical Service Bulletin (TSB) 18-48-98 has been performed. NOTE: IT IS IMPORTANT THAT THE COIL AND SPARK PLUG WIRES ARE ROUTED EXACTLY AS SPECIFIED IN TSB 18-48-98 TO ACHIEVE THE MOST BENEFIT. Inspect the Positive Crankcase Ventilation (PCV) valve. Shake the PCV valve to verify that the pintle inside of the PCV valve is free. Replace the PVC if the pintle is not free. If the intake manifold plenum pan gasket is leaking, an additional vacuum source will be created inside of the engine at the location of the pan gasket leakage. Engine combustion blow-by gases, oil vapor, and air from the crankcase filter/breather may be drawn past the leaking pan gasket and into the intake manifold. In most cases when this condition occurs, an engine at idle will create the highest vacuum and lowest amount of engine blow-by. 1. Allow the engine to reach normal operating temperature. 2. Stop the engine. 3. Disconnect the breather hose from the air cleaner. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Intake Manifold > Component Information > Technical Service Bulletins > Customer Interest for Intake Manifold: > 09-05-00 > Feb > 00 > Engine - Spark Knock/Oil Consumption > Page 1396 4. Attach a vacuum/pressure gauge to the end of the breather hose (Figure 1). 5. Disconnect the PCV valve hose from the intake manifold. 6. Seal off the intake manifold PCV valve hose port opening. 7. Seal off the open end of the PCV valve hose (Figure 2). NOTE: DURING THIS DIAGNOSIS, IT WOULD BE NORMAL FOR THE ENGINE TO DEVELOP PRESSURE WITHIN THE ENGINE CRANKCASE. THIS IS DUE TO THE NORMAL PROCESS OF EXHAUST BLOW-BY GASES LEAKING PAST THE ENGINE PISTON RINGS AND ACCUMULATING IN THE ENGINE CRANKCASE. DO NOT ALLOW MORE THAN 3 PSI (20.7 kpa) OF PRESSURE TO BUILD WITHIN THE ENGINE WHEN PERFORMING THE FOLLOWING DIAGNOSTIC PROCEDURE. 8. Start the warmed engine and observe the vacuum gauge. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Intake Manifold > Component Information > Technical Service Bulletins > Customer Interest for Intake Manifold: > 09-05-00 > Feb > 00 > Engine - Spark Knock/Oil Consumption > Page 1397 9. Allow the engine to idle for approximately 30 seconds. Do not allow more than 3 psi (20.7 kPa) of pressure to develop in the engine crankcase. 10. If the attached vacuum / pressure gauge does not indicate that a vacuum is present in the engine crankcase, then the intake manifold plenum pan gasket is good and no further internal engine vacuum leak diagnosis is required. 11.

An engine cylinder head gasket leak can be located between adjacent cylinders or between a cylinder and the adjacent water jacket. An engine cylinder head gasket leaking between adjacent cylinders is indicated by a loss of power and/or engine misfire. - An engine cylinder head gasket leaking between a cylinder and an adjacent water jacket is indicated by coolant foaming or overheating and loss of coolant. Cylinder To Cylinder Leakage Test To determine if an engine cylinder head gasket is leaking between adjacent cylinders, follow the procedures outlined in Cylinder Compression Pressure Test. An engine cylinder head gasket leaking between adjacent cylinders will result in approximately a 50-70% reduction in compression pressure. Cylinder To Water Jacket Leakage Test WARNING: Use extreme caution when the engine is operating. Do not stand in a direct line with the fan. Do not put your hands near the pulleys, belts, oft the fan. Do not wear loose clothing. Remove the radiator cap. Start the engine and allow it to warm up until the engine thermostat opens. If a large combustion/compression pressure leak exists, bubbles will be visible in the coolant. If bubbles are not visible, install a radiator pressure tester and pressurize the coolant system. If a cylinder is leaking combustion pressure into the water jacket, the tester pointer will pulsate with every combustion stroke of the cylinder. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Front Crankshaft Seal > Component Information > Service and Repair Front Crankshaft Seal: Service and Repair The oil seal can be replaced without removing the timing chain cover provided the cover is not misaligned. 1. Disconnect the negative cable from the battery. 2. Remove vibration damper. 3. If front seal is suspected of leaking, check front oil seal alignment to crankshaft. The seal installation/alignment tool 6635, should fit with minimum interference. If tool does not fit, the cover must be removed and installed properly. 4. Place a suitable tool behind the lips of the oil seal to pry the oil seal outward. Be careful not to damage the crankshaft seal bore of cover. Placing Oil Seal On Installation Tool 6635 5. Place the smaller diameter of the oil seal over Front Oil Seal Installation Tool 6635. Seat the oil seal in the groove of the tool. Position Tool And Seal Onto Crankshaft 6.

THIS IS A COMPLETE REVISION AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS. SUBJECT: Spark Knock And Engine Oil Consumption Due To Intake Manifold Pan Gasket Oil Leak OVER VIEW: This bulletin involves the replacement of the engine intake manifold plenum pan gasket. NOTE: THIS BULLETIN APPLIES TO VEHICLE EQUIPPED WITH A 3.9L, 5.2L. OR 5.9L GASOLINE ENGINE. SYMPTOM/CONDITION: An engine intake manifold plenum pan gasket oil leak may occur on some V-6 and V-8 style engines. The oil leak is internal to the engine so no external oil leakage will be present. Two symptoms of this oil leak condition may be present. The vehicle operator may experience an engine spark knock during acceleration and/or an increase in the amount of engine oil consumed by the engine. DIAGNOSIS: Make sure Technical Service Bulletin (TSB) 18-48-98 has been performed. NOTE: IT IS IMPORTANT THAT THE COIL AND SPARK PLUG WIRES ARE ROUTED EXACTLY AS SPECIFIED IN TSB 18-48-98 TO ACHIEVE THE MOST BENEFIT. Inspect the Positive Crankcase Ventilation (PCV) valve. Shake the PCV valve to verify that the pintle inside of the PCV valve is free. Replace the PVC if the pintle is not free. If the intake manifold plenum pan gasket is leaking, an additional vacuum source will be created inside of the engine at the location of the pan gasket leakage. Engine combustion blow-by gases, oil vapor, and air from the crankcase filter/breather may be drawn past the leaking pan gasket and into the intake manifold. In most cases when this condition occurs, an engine at idle will create the highest vacuum and lowest amount of engine blow-by. 1. Allow the engine to reach normal operating temperature. 2. Stop the engine. 3. Disconnect the breather hose from the air cleaner. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Intake Manifold Gasket > Component Information > Technical Service Bulletins > Customer Interest for Intake Manifold Gasket: > 09-05-00 > Feb > 00 > Engine - Spark Knock/Oil Consumption > Page 1443 4. Attach a vacuum/pressure gauge to the end of the breather hose (Figure 1). 5. Disconnect the PCV valve hose from the intake manifold. 6. Seal off the intake manifold PCV valve hose port opening. 7. Seal off the open end of the PCV valve hose (Figure 2). NOTE: DURING THIS DIAGNOSIS, IT WOULD BE NORMAL FOR THE ENGINE TO DEVELOP PRESSURE WITHIN THE ENGINE CRANKCASE. THIS IS DUE TO THE NORMAL PROCESS OF EXHAUST BLOW-BY GASES LEAKING PAST THE ENGINE PISTON RINGS AND ACCUMULATING IN THE ENGINE CRANKCASE. DO NOT ALLOW MORE THAN 3 PSI (20.7 kpa) OF PRESSURE TO BUILD WITHIN THE ENGINE WHEN PERFORMING THE FOLLOWING DIAGNOSTIC PROCEDURE. 8. Start the warmed engine and observe the vacuum gauge. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Seals and Gaskets, Engine > Intake Manifold Gasket > Component Information > Technical Service Bulletins > Customer Interest for Intake Manifold Gasket: > 09-05-00 > Feb > 00 > Engine - Spark Knock/Oil Consumption > Page 1444 9.

Use this test in conjunction with the Fuel Pressure Leak Down Test. 1. Release fuel system pressure. Refer to the Fuel Pressure Release Procedure. 2. Disconnect fuel supply line at fuel rail. Some engines may require air cleaner housing removal before line disconnection. 3. Connect appropriate Fuel Line Pressure Test Adapter Tool Hose (number 6631, 6923, 6541 or 6539) into disconnected fuel supply line. Insert other end of Adaptor Tool hose into a graduated container. 4. Remove fuel fill cap. 5. To activate fuel pump and pressurize system, obtain DRB scan tool and actuate ASD Fuel System Test. 6. A good fuel pump will deliver at least 1/4 liter of fuel in 7 seconds. Do not operate fuel pump for longer than 7 seconds with fuel line disconnected as fuel pump module reservoir may run empty. a. If capacity is lower than specification, but fuel pump can be heard operating through fuel fill cap opening, check for a kinked/damaged fuel supply line somewhere between fuel rail and fuel pump module. b. If line is not kinked/damaged, and fuel pressure is OK, but capacity is low, replace fuel filter/ fuel pressure regulator. The filter/regulator may be serviced separately on certain applications. Refer to Fuel Filter/Fuel Pressure Regulator Removal/Installation for additional information. c. If both fuel pressure and capacity are low, replace fuel pump module assembly Refer to Fuel Pump Module Removal/Installation. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 1490 Fuel Pressure: Testing and Inspection Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity Test. Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: - Fuel pressure bleeding past a fuel injector(s). - Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose. Tool number 6539 is used for 5/16" fuel lines and tool number 6631 is used for 3/8" fuel lines. Connecting Adapter Tool-Typical Connecting Adapter Tool-Typical 3. Connect correct Fuel Line Pressure Test Adapter Tool Hose between disconnected fuel line and fuel rail. 4. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 1491 6. Observe test gauge. Normal operating pressure should be 339 kPa ± 34 kPa (49.2 psi ± 5 psi). 7. Shut engine off. 8. Pressure should not fall below 30 psi for five minutes. 9. If pressure falls below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine off. 12. Testing for fuel injector or fuel rail leakage: Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking. 13. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage: Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line. If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump or filter/regulator may be leaking. Note: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A slow loss of pressure usually indicates a defective check valve in the electric fuel pump. The electric fuel pump is not serviced separately. Replace the fuel pump module assembly. The filter/ regulator may be replaced separately on certain applications. Refer to Fuel Filter/Fuel Pressure Regulator Removal/installation for additional information. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Idle Speed > System Information > Specifications Idle Speed: Specifications Minimum Air Flow Idle ......................................................................................................................... ......................................................... 500 to 900 rpm Note: Idle speed range achieved through Minimum Air Flow Idle Test Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Idle Speed > System Information > Specifications > Page 1495 Idle Speed: Testing and Inspection The following test procedure has been developed to check throttle body calibrations for correct idle conditions.

These cables transfer electrical current from the ignition coil(s) and/or distributor, to individual spark plugs at each cylinder. The resistive spark plug cables are of nonmetallic construction. The cables provide suppression of radio frequency emissions from the ignition system. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 1539 Ignition Cable: Testing and Inspection Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and spark plugs. Terminals should be fully seated. The insulators should be in good condition and should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are cracked or torn must be replaced. Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the cables dry. Check for brittle or cracked insulation. Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable boot and spark plug. These shields protect the spark plug boots from damage (due to intense engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat shield. Testing When testing secondary cables for damage with an oscilloscope, follow the instructions of the equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as follows: CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during testing. This may cause possible heat damage to the catalytic converter. Total test time must not exceed ten minutes. With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to a good engine ground. If the cable and spark plug are in good condition, the engine rpm should drop and the engine will run poorly. If engine rpm does not drop, the cable and/or spark plug may not be operating properly and should be replaced. Also check engine cylinder compression. With the engine not running, connect one end of a test probe to a good ground. Start the engine and run the other end of the test probe along the entire length of all spark plug cables. If cables are cracked or punctured, there will be a noticeable spark jump from the damaged area to the test probe. The cable running from the ignition coil to the distributor cap can be checked in the same manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket. Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped, remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable. Test all spark plug cables in this manner. SPARK PLUG CABLE RESISTANCE MINIMUM = MAXIMUM 250 Ohms Per Inch = 1000 Ohms Per Inch 3000 Ohms Per Foot = 12,000 Ohms Per Foot To test ignition coil-to-distributor cap cable, do not remove the cable from the cap. Connect ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace the cable. Inspect the ignition coil tower for cracks, burns or corrosion. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 1540 Ignition Cable: Service and Repair REMOVAL AND INSTALLATION Cable Removal CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap, twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off with a steady, even force. Engine Firing Order Install cables into the proper engine cylinder firing order. When replacing the spark plug and coil cables, route the cables correctly and secure in the proper retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could also cause cross ignition of the plugs or short circuit the cables to ground. When installing new cables, make sure a positive connection is made. A snap should be felt when a good connection is made between the plug cable and the distributor cap tower. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Distributor, Ignition > Distributor Cap > Component Information > Testing and Inspection Distributor Cap: Testing and Inspection Cap Inspection - External - Typical Cap Inspection - Internal - Typical Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the inside (caused by condensation entering the cap through cracks) Replace any cap that displays charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence of mechanical interference with the rotor tip. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Distributor, Ignition > Ignition Rotor > Component Information > Testing and Inspection Ignition Rotor: Testing and Inspection Rotor Inspection - Typical Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip. Also check for evidence of mechanical interference with the cap. Some charring is normal on the end of the metal tip. The silicone-dielectric-varnish-compound applied to the rotor tip for radio interference noise suppression, will appear charred. This is normal. Do not remove the charred corn- pound. Test the spring for insufficient tension. Replace a rotor that displays any of these adverse conditions. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications Spark Plug: Specifications Electrode Gap ...................................................................................................................................... ..................................................... 1.01 mm (0.040 in) Torque ............................................................ ............................................................................................................................................. 41 Nm (30 ft. lb.) Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1551 Spark Plug: Application and ID Plug Type ............................................................................................................................................ ....................................................................

Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in which they were removed from the engine. A single plug displaying an abnormal condition indicates that a problem exists in the corresponding cylinder. Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or oil fouled. Refer to the Spark Plug Condition. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1553 Spark Plug: Testing and Inspection SPARK PLUG CONDITIONS Normal Operation And Cold (Carbon) Fouling NORMAL OPERATING The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is evident with most grades of commercial gasoline. There will not be evidence of electrode burning. Gap growth will not average more than approximately 0.025 mm (0.001 in) per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the electrodes filed, have the gap set and then be installed. Some fuel refiners in several areas of the United States have introduced a manganese additive (MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits. COLD FOULING/CARBON FOULING Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be caused by a clogged air cleaner element or repeated short operating times (short trips). WET FOULING OR GAS FOULING A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the fouled plugs. Oil Or Ash Encrusted OIL OR ASH ENCRUSTED Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1554 If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of oil entry into that particular combustion chamber. Electrode Gap Bridging ELECTRODE GAP BRIDGING Electrode gap bridging may be traced to loose deposits in the combustion chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be cleaned using standard procedures. Scavenger Deposits SCAVENGER DEPOSITS Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is a normal condition caused by chemical additives in certain fuels. These additives are designed to change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in condition and can be cleaned using standard procedures. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1555 Chipped Electrode Insulator CHIPPED ELECTRODE INSULATOR A chipped electrode insulator usually results from bending the center electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation can also separate the insulator from the center electrode. Spark plugs with this condition must be replaced. Preignition Damage PREIGNITION DAMAGE Preignition damage is usually caused by excessive combustion chamber temperature. The center electrode dissolves first and the ground electrode dissolves somewhat latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine. Determine if ignition timing is over advanced or if other operating conditions are causing engine overheating. (The heat range rating refers to the operating temperature of a particular type spark plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon the thickness and length of the center electrodes porcelain insulator.) Spark Plug Overheating SPARK PLUG OVERHEATING Overheating is indicated by a white or gray center electrode insulator that also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug overheating. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1556 Spark Plug: Service and Repair Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each cable boot and spark plug. If removal of the heat shield(s) is necessary,remove the spark plug cable and compress the sides of shield for removal. Each shield is slotted to allow for compression and removal. To install the shields, align shield to machined opening in cylinder head and tap into place with a block of wood. PLUG REMOVAL Cable Removal 1. Always remove spark plug or ignition coil cables by grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady motion. Never pull directly on the cable. Internal damage to cable will result. 2. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area around the spark plug. This will help prevent foreign material from entering the combustion chamber. 3. Remove the spark plug using a quality socket with a rubber or foam insert. 4. Inspect the spark plug condition. Refer to Spark Plug Condition in the Diagnostics and Testing. PLUG CLEANING The plugs may be cleaned using commercially available spark plug cleaning equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before adjusting gap. CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will remain on the spark plug insulator and will cause plug misfire. PLUG GAP ADJUSTMENT Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 1557 Setting Spark Plug Gap - Typical Check the spark plug gap with a gap gauge tool. If the gap is not correct, adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center electrode. SPARK PLUG GAP 1.01 mm (0.040 in) PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged. Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator. When replacing the spark plug and ignition coil cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground. 1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark plugs to 35-41 N-m (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications Compression Check: Specifications Compression should not be less than 689 kPa (100 psi) and not vary more than 172 kPa (25 psi) from cylinder to cylinder. If cylinder(s) have abnormally low compression pressures, repeat procedure. - If the same cylinder(s) repeat an abnormally low reading, it could indicate the existence of a problem in the cylinder. NOTE: The recommended compression pressures are to be used only as a guide to diagnosing engine problems. An engine should NOT be disassembled to determine the cause of low compression unless some malfunction is present. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications > Page 1561 Compression Check: Testing and Inspection The combustion pressure leakage test provides an accurate means for determining engine condition. Combustion pressure leakage testing will detect: ^ Exhaust and intake valve leaks (improper seating). ^ Leaks between adjacent cylinders or into water jacket. ^ Any causes for combustion/compression pressure loss. 1. Check the coolant level and fill as required. DO NOT install the radiator cap. 2. Start and operate the engine until it attains normal operating temperature, then turn the engine OFF. 3. Remove the spark plugs. 4. Remove the oil filler cap. 5. Remove the air cleaner. 6. Calibrate the tester according to the manufacturer's instructions. The shop air source for testing should maintain 483 kPa (70 psi) minimum, 1,379 kPa (200 psi) maximum and 552 kPa (80 psi) recommended. 7. Perform the test procedures on each cylinder according to the tester manufacturer's instructions. While testing, listen for pressurized air escaping through the throttle body, tailpipe and oil filler cap opening. Check for bubbles in the radiator coolant.

The pump is driven from the engine crankshaft by a drive belt. The water pump impeller is pressed onto the rear of a shaft that rotates in a bearing pressed into the water pump body. The body has a small hole for ventilation. The water pump seals are lubricated by antifreeze in the coolant mixture. Additional lubrication is not necessary. A quick test to determine if pump is working is to check if heater warms properly. A defective water pump will not be able to circulate heated coolant through the long heater hose to the heater core. 3.9L/5.2L/5.9L ENGINE The water pump is bolted directly to the engine timing case/cover. A gasket is used as a seal between the water pump and timing chain case/cover. 2.5L ENGINE Reverse Rotating Water Pump-Typical CAUTION: The 2.5L engine is equipped with a reverse (counter-clockwise) rotating water pump. The letter R is stamped into the back of the water pump impeller. Engines from previous model years, depending upon application, may have been equipped with a forward (clockwise) rotating water pump. Installation of the wrong water pump will cause engine overheating. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Water Pump > Component Information > Specifications > Page 1569 Water Pump: Testing and Inspection Replace water pump assembly if it has any of the following conditions: ^ The body is cracked or damaged ^ Water leaks from shaft seal.

The recommended mixture of 50/50 ethylene-glycol and water will provide protection against freezing to -37° C (-35° F). The antifreeze concentration must always be a minimum of 44%, year round, in all climates. If percentage is lower than 44%, engine parts may be eroded by cavitation, and cooling system components may be severely damaged by corrosion. Maximum protection against freezing is provided with a 68% antifreeze concentration, which prevents freezing down to -67.7° C (-90° F). A higher percentage will freeze at a warmer temperature. Also, a higher percentage of antifreeze can cause the engine to overheat because the specific heat of antifreeze is lower than that of water. 100 Percent Ethylene-Glycol Should Not Be Used Use of 100 Percent Ethylene-Glycol will cause formation of additive deposits in the system, as the corrosive inhibitive additives in ethylene-glycol require the presence of water to dissolve. The deposits act as insulation, causing temperatures to rise as high as 149° C (300° F). this temperature is hot enough to melt plastic and soften solder. The increased temperature can result in engine detonation. In addition, 100 % ethylene-glycol freezes at 22° C (-8° F). Propylene-Glycol Formulations Should Not Be Used Propylene-glycol formulations do not meet the required specifications. It's overall effective temperature range is smaller than that of ethylene-glycol. The freeze point of 50/50 propylene-glycol and water is -32° C (-26° F), 5 degrees higher than ethylene-glycol's freeze point. The boiling point (protection against summer boil-over) of propylene-glycol is 125° C (257° F) at 96.5 kPa (14 PSI), compared to 128° C (263° F) for ethylene-glycol. Use of propylene-glycol can result in boil-over and freeze up. Propylene-Glycol also has a poorer heat transfer characteristics than ethylene-glycol. This can increase cylinder head temperatures under certain conditions. Propylene-Glycol/Ethylene-Glycol Mixtures Should Not Be Used Propylene-glycol/ethylene-glycol mixtures can cause the destabilization of various corrosion inhibitors, causing damage to the coling system components. Also, once ethylene-glycol and propylene-glycol based coolants are mixed in the vehicle, conventional methods of determining the freeze point will not be accurate. Both the refractive index and specific gravity differ between the ethylene-glycol and propylene-glycol. CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can cause problems associated with 100 percent ethylene-glycol. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Coolant > Component Information > Specifications > Page 1580 Coolant: Service Precautions DO NOT mix green colored coolant with orange colored coolant. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Coolant > Component Information > Description and Operation > Ethylene-Glycol Mixtures Coolant: Description and Operation Ethylene-Glycol Mixtures The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and vehicle operating conditions.

This noise is created by a large cooling fan that is required to provide optimum cooling for low vehicle speed operation in hot weather conditions and for heavy trailer towing. Since the large cooling fan is unnecessary in most operating conditions, these vehicles are also equipped with viscous fan drives that allow the fan to operate at variable speeds based upon temperature loads. The viscous fan drive will engage the fan for maximum cooling when temperatures are high and allow the fan to operate at slower speeds when temperatures are low. In addition, at engine start-up, the viscous fan drive engages the fan for maximum cooling until the fluid in the viscous clutch can dissipate out of the clutch drive grooves allowing the fan to operate at a slower speed. Because of the viscous fan drive, the noise may occur during high temperature conditions and for the first 1-2 minutes of operation. Due to the roar of the fan, customers may also complain of a perceived loss of power, automatic transmission slippage, or that the transmission is slaying into a low gear too long (delayed upshift). Customers concerned about this noise should be advised that this condition is normal and no repair attempts should be made.

DISCUSSION: Vehicles built after January 5, 1998 have the water pump pulley pressed onto the water pump hub shaft. As in previous models, the viscous fan drive is threaded onto the water pump hub shaft. Because the pulley is pressed onto the hub shaft, viscous fan drive removal/installation procedures are unique. The fan/viscous fan drive assembly can be removed or installed from the water pump by turning the mounting nut. To remove the fan/viscous fan drive assembly, turn the nut counterclockwise as viewed from the front. To install the fan/viscous fan drive assembly, turn the nut clockwise as viewed from the front. Threads on the viscous fan drive are RIGHT-HANDED. Snap-On 36 mm Fan Wrench (number SP346 from Snap-On Cummins Diesel Tool Set number 2017DSP) can be used to remove/install the fan drive assembly on gasoline engines. To hold the water pump pulley from rotating, place Miller Special Tool 6958 Spanner Wrench onto the water pump pulley with adapter pins 8346 inserted into the holes on the pulley (Figure 1).

The coupling allows the fan to be driven in a normal manner. This is done at low engine speeds while limiting the top speed of the fan to a predetermined maximum level at higher engine speeds. A thermostatic bimetallic spring coil is located on the front face of the viscous fan drive unit. This spring coil reacts to the temperature of the radiator discharge air. It engages the viscous fan drive for higher fan speed if the air temperature from the radiator rises above a certain point. Until additional engine cooling is necessary, the fan will remain at a reduced rpm regardless of engine speed. Only when sufficient heat is present, will the viscous fan drive engage. This is when the air flowing through the radiator core causes a reaction to the bimetallic coil. It then increases fan speed to provide the necessary additional engine cooling. Once the engine has cooled, the radiator discharge temperature will drop. The bimetallic coil again reacts and the fan speed is reduced to the previous disengaged speed. CAUTION: Engines equipped with accessory drive belts have reverse rotating fans and viscous fan drives. They are marked with the word REVERSE to designate their usage. Installation of the wrong fan or viscous fan drive can result in engine overheating. CAUTION: If the viscous fan drive is replaced because of mechanical damage, the cooling fan blades should also be inspected. Inspect for fatigue cracks, loose blades, or loose rivets that could have resulted from excessive vibration. Replace fan blade assembly if any of these conditions are found. Also inspect water pump bearing and shaft assembly for any related damage due to a viscous fan drive malfunction. NOISE NOTE: It is normal for fan noise to be louder (roaring) when: Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cooling Fan > Fan Clutch > Component Information > Technical Service Bulletins > Page 1611 ^ The underhood temperature is above the engagement point for the viscous drive coupling. This may occur when ambient (outside air temperature) is very high. ^ Engine loads and temperatures are high such as when towing a trailer. ^ Cool silicone fluid within the fan drive unit is being redistributed back to its normal disengaged (warm) position. This can occur during the first 15 seconds to one minute after engine start-up on a cold engine. LEAKS Viscous fan drive operation is not affected by small oil stains near the drive bearing.

This spin test must be performed when the engine is cool. For the following test, the cooling system must be in good condition. It also will ensure against excessively high coolant temperature. WARNING: BE SURE THAT THERE IS ADEQUATE FAN BLADE CLEARANCE BEFORE DRILLING. 1. Drill a 3.18 mm (1/8 inch) diameter hole in the top center of the fan shroud. 2. Obtain a dial thermometer with an 8 inch stem (or equivalent). It should have a range of -18° to 105°C (0° to 220°F). Insert thermometer through the hole in the shroud. Be sure that there is adequate clearance from the fan blades. 3. Connect a tachometer and an engine ignition timing light (timing light is to be used as a strobe light). 4. Block the air flow through the radiator. Secure a sheet of plastic in front of the radiator (or air conditioner condenser). Use tape at the top to secure the plastic and be sure that the air flow is blocked. 5. Be sure that the air conditioner (if equipped) is turned off. WARNING: USE EXTREME CAUTION WHEN THE ENGINE IS OPERATING. DO NOT STAND IN A DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING. 6. Start the engine and operate at 2400 rpm. Within ten minutes the air temperature (indicated on the dial thermometer) should be up to 88°C (190° F). Fan drive engagement should have started to occur at between 74° to 82°C (165° to 180°F). Engagement is distinguishable by a definite increase in fan flow noise (roaring).

The sensor provides an input voltage to the powertrain control module (PCM) relating coolant temperature. The PCM uses this input along with inputs from other sensors to determine injector pulse width and ignition timing. As coolant temperature varies, the coolant temperature sensor resistance will change. This change in resistance results in a different input voltage to the PCM. When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air-fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 1622 Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection To perform a complete test of the engine coolant temperature sensor and its circuitry, refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures.

It is a heat exchanger made of rows of tubes and fins. Engine coolant is circulated through heater hoses to the heater core at all times. As the coolant flows through the heater core, heat removed from the engine is transferred to the heater core fins and tubes. Air directed through the heater core picks up the heat from the heater core fins. The blend air door allows control of the heater output air temperature by controlling how much of the air flowing through the heater-A/C housing is directed through the heater core. The blower motor speed controls the volume of air flowing through the heater-A/C housing. The heater core cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Heater Core > Component Information > Locations > Page 1632 Heater Core: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

The pressure relief point (in pounds) is engraved on top of cap. Radiator Pressure Cap And Filler Neck The cooling system will operate at pressures slightly above atmospheric pressure. This results in a higher coolant boiling point allowing increased radiator cooling capacity. The cap contains a spring-loaded pressure relief valve that opens when system pressure reaches release range of 97 124 kPa (14 - 18 psi). A vent valve in the center of cap allows a small coolant flow through cap when coolant is below boiling temperature. The valve is completely closed when boiling point is reached. As the coolant cools, it contracts and creates a vacuum in the cooling system. This causes the vacuum valve to open and coolant in the reserve/overflow tank to be drawn through its connecting hose into radiator. If the vacuum valve is stuck shut, the radiator hoses will collapse on cooldown. Clean the vent valve. A rubber gasket seals radiator filler neck to prevent leakage. This is done to keep system under pressure. It also maintains vacuum during coolant cool-down allowing coolant to return from reserve/ overflow tank. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cap > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview Radiator Cap: Initial Inspection and Diagnostic Overview Hold cap at eye level, right side up. The vent valve at bottom of cap should open. If rubber gasket has swollen and prevents vent valve from opening, replace cap. Hold cap at eye level, upside down. If any light can be seen between vent valve and rubber gasket, replace cap. Do not use a replacement cap that has a spring to hold vent shut. A replacement cap must be the type designed for a coolant reserve/overflow system with a completely sealed diaphragm spring and a rubber gasket. This gasket is used to seal to radiator filler neck top surface. Use of proper cap will allow coolant return to radiator. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Radiator Cap > Component Information > Testing and Inspection > Initial Inspection and Diagnostic Overview > Page 1642 Radiator Cap: Component Tests and General Diagnostics Radiator Cap - Pressure Testing Pressure Testing Radiator Cap-Typical Remove cap from radiator. Be sure that sealing surfaces are clean. Moisten rubber gasket with water and install cap on pressure tester 7700 or an equivalent. Operate tester pump to bring pressure to 104 kPa (15 psi) on gauge. If pressure cap fails to hold pressure of at least 97 kPa (14 psi) replace cap. Refer to following CAUTION. The pressure cap may test properly while positioned on tool 7700 (or equivalent). It may not hold pressure or vacuum when installed on radiator. If so, inspect radiator filler neck and cap's top gasket for damage. Also inspect for dirt or distortion that may prevent cap from sealing properly. CAUTION: Radiator pressure testing tools are very sensitive to small air leaks, which will not cause cooling system problems. A pressure cap that does not have a history of coolant loss should not be replaced just because it leaks slowly when tested with this tool. Add water to tool. Turn tool upside down and recheck pressure cap to confirm that cap needs replacement. Radiator Cap to Filler Neck Seal - Pressure Relief Check PRESSURE RELIEF CHECK The pressure cap upper gasket (seal) pressure relief can be tested by removing overflow hose from radiator filler neck nipple. Attach hose of pressure tester tool 7700 (or equivalent) to nipple. It will be necessary to disconnect hose from its adapter for filler neck. Pump air into radiator. The pressure cap upper gasket should relieve at 69 - 124 kPa (10 - 18 psi) and hold pressure at a minimum of 55 kPa (8 psi). WARNING: THE WARNING WORDS -DO NOT OPEN HOT- ON RADIATOR PRESSURE CAP, ARE A SAFETY PRECAUTION. WHEN HOT, PRESSURE BUILDS UP IN COOLING SYSTEM. TO PREVENT SCALDING OR INJURY, RADIATOR CAP SHOULD NOT BE REMOVED WHILE SYSTEM IS HOT AND/OR UNDER PRESSURE. Do not remove radiator cap at any time except for the following purposes: 1. Check and adjust antifreeze freeze point. 2. Refill system with new antifreeze. 3. Conducting service procedures. 4. Checking for vacuum leaks. WARNING: IF VEHICLE HAS BEEN RUN RECENTLY, WAIT AT LEAST 15 MINUTES BEFORE REMOVING RADIATOR CAP. WITH A RAG, SQUEEZE RADIATOR UPPER HOSE TO CHECK IF SYSTEM IS UNDER PRESSURE. PLACE A RAG OVER CAP AND WITHOUT PUSHING CAP DOWN, ROTATE IT COUNTERCLOCKWISE TO FIRST STOP. ALLOW FLUID TO ESCAPE THROUGH THE COOLANT RESERVE/ OVERFLOW HOSE INTO RESERVE/OVERFLOW TANK. SQUEEZE RADIATOR UPPER HOSE TO DETERMINE WHEN PRESSURE HAS BEEN RELEASED. WHEN COOLANT AND STEAM STOP BEING PUSHED INTO TANK AND SYSTEM PRESSURE DROPS, REMOVE RADIATOR CAP COMPLETELY. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Relays and Modules - Cooling System > Radiator Cooling Fan Motor Relay > Component Information > Locations 8w-10-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Relays and Modules - Cooling System > Radiator Cooling Fan Motor Relay > Component Information > Locations > Page 1647 Radiator Cooling Fan Motor Relay: Diagrams 8w-10-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Relays and Modules - Cooling System > Radiator Cooling Fan Motor Relay > Component Information > Locations > Page 1648 8w-10-6 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Sensors and Switches - Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications Coolant Temperature Sensor/Switch (For Computer): Specifications Engine Coolant Temperature Sensor 11 Nm Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Sensors and Switches - Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 1654 Coolant Temperature Sensor/Switch (For Computer): Locations Engine Coolant Temperature Sensor Intake Air Temperature Sensor, Engine Coolant Temparature Sensor Connector, Ignition Coil The engine coolant temperature sensor is installed into a water jacket at the front of the intake manifold located near the rear of the generator. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Sensors and Switches - Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 1655 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Sensors and Switches - Cooling System > Engine - Coolant Temperature Sensor/Switch > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 1656 Coolant Temperature Sensor/Switch (For Computer): Service Precautions WARNING: HOT, PRESSURIZED COOLANT CAN CAUSE INJURY BY SCALDING.

The wax pellet is located in a sealed container at spring end of thermostat. When heated, the pellet expands, overcoming closing spring tension and water pump pressure to force valve to open. Coolant leakage into pellet container will cause thermostat to fail in open position. Do not attempt to free a sticking thermostat with a prying device. The thermostat controls the operating temperature of the engine by controlling the amount of coolant flow to radiator. On all engines (2.5L, 3.9L and 5.21L 5.9L), thermostat is closed below 88°C (192°F). When coolant reaches this temperature, thermostat begins to open allowing coolant flow to radiator. This provides quick engine warm-up and overall temperature control. The thermostat is designed to provide a minimum engine operating temperature range of from 88 to 93°C (192 to 199°F). The thermostat should be fully open for maximum coolant flow during operation in hot ambient temperatures of approximately 104°C (220°F). Above 104°C (220°F), coolant temperature is controlled by radiator, fan and ambient temperature. An arrow, plus the word UP is stamped on front Range next to air bleed. The words TO RAD are stamped on one arm of thermostat. They indicate proper installed position. The same thermostat is used for winter and summer seasons. CAUTION: Do not operate an engine without a thermostat, except for servicing or testing. An engine should not be operated without a thermostat, except for servicing or testing. Operating without a thermostat causes longer engine warm-up time, unreliable warm-up performance, increased exhaust emissions and crankcase condensation that can result in sludge formation. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Thermostat, Engine Cooling > Component Information > Specifications > Page 1664 Thermostat: Testing and Inspection All models are equipped with On-Board Diagnostics for certain cooling system components. Refer to On-Board Diagnostics (OBD) in Powertrain Management for additional information.

The pump is driven from the engine crankshaft by a drive belt. The water pump impeller is pressed onto the rear of a shaft that rotates in a bearing pressed into the water pump body. The body has a small hole for ventilation. The water pump seals are lubricated by antifreeze in the coolant mixture. Additional lubrication is not necessary. A quick test to determine if pump is working is to check if heater warms properly. A defective water pump will not be able to circulate heated coolant through the long heater hose to the heater core. 3.9L/5.2L/5.9L ENGINE The water pump is bolted directly to the engine timing case/cover. A gasket is used as a seal between the water pump and timing chain case/cover. 2.5L ENGINE Reverse Rotating Water Pump-Typical CAUTION: The 2.5L engine is equipped with a reverse (counter-clockwise) rotating water pump. The letter R is stamped into the back of the water pump impeller. Engines from previous model years, depending upon application, may have been equipped with a forward (clockwise) rotating water pump. Installation of the wrong water pump will cause engine overheating. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Water Pump > Component Information > Specifications > Page 1675 Water Pump: Testing and Inspection Replace water pump assembly if it has any of the following conditions: ^ The body is cracked or damaged ^ Water leaks from shaft seal.

Excessive heat can result in bulging or other distortion, but excessive heat will not be the fault of the converter. If unburned fuel enters the converter, overheating may occur. If a converter is heat-damaged, correct the cause of the damage at the same time the converter is replaced. Also, inspect all other components of the exhaust system for heat damage. Unleaded gasoline must be used to avoid contaminating the catalyst core. DO NOT remove spark plug wires from plugs or by any other means short out cylinders. Failure of the catalytic converter can occur due to a temperature increase caused by unburned fuel passing through the converter. DO NOT allow the engine to operate at fast idle for extended periods (over 5 minutes). This condition may result in excessive temperatures in the exhaust system and on the floor pan. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Engine, Cooling and Exhaust > Exhaust System > Catalytic Converter > Component Information > Description and Operation > Page 1684 Catalytic Converter: Service and Repair CAUTION: When servicing or replacing exhaust system components, disconnect the oxygen sensor connector(s).

Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System Central Timer Module ( CTM ) High Option: Description and Operation Airbag System AIRBAG SYSTEM The airbag system is designed to provide increased driver and passenger protection if the vehicle is involved in a front end collision. The system is most effective when used in conjunction with the seat belt system. The airbag control module (ACM) is an electronic module that monitors the airbag system for proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and contains the sensor and actuator that is responsible for airbag deployment. There are no external impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck at the bottom of the instrument panel. It is located forward of the console. The ACM provides diagnostic information (DTCs) to the technician through the DRB III(R) via the CCD bus.Some circuits are tested continuously; others are checked only under certain circumstances. The warning lamp is driven with messages relayed to the Mechanical Instrument Cluster (MIC) from the ACM via the CCD bus. The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be observed by the customer. Whenever the ignition key is turned to the "run" or "start" position,the airbag control module performs a lamp check by turning the AIRBAG warning lamp on for 6 - 8 seconds. If the lamp remains off, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains on, there could be an active fault in the system or the circuit that operates the lamp may be shorted to ground. If the lamp comes on and stays on for a period longer than 6-8 seconds, then goes off, there is usually an intermittent problem in the system. Perform the WARNING LAMP CIRCUIT OPEN procedure (refer to Testing and Inspection in this section) to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 1720 Central Timer Module ( CTM ) High Option: Description and Operation Interior Lighting INTERIOR LIGHTING The courtesy lights are controlled by the CTM. The door switches are inputs to the CTM and the courtesy lights are outputs. The glove box lamp and the ash receiver lamp (if equipped) are not controlled by the CTM. They are hardwired to individual switches and fuses. The highline CTM also provides for illuminated entry option. If the CTM detects an unlock signal from the RKE transmitter, a door disarm switch input or the door jamb switch input, the interior courtesy lights will be turned on. The illuminated entry function is canceled if the CTM senses an ignition "on" condition or the "lock" command from a valid key fob If a door is left open or turned on by rotation of dimmer switch for more than fifteen minutes, the CTM will extinguish the lamps to avoid discharging the battery. If the lamps are turned on by courtesy lamp switch, the CTM will not be able to turn them off. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 1721 Central Timer Module ( CTM ) High Option: Description and Operation Central Timer Module CENTRAL TIMER MODULE The Dakota (AN) utilizes a Central Timer Module (CTM). This system is available in a Base or Highline configuration. The Base CTM does not communicate on the CCD bus and will not be addressed. For concerns about the Base CTM, please refer to the appropriate Service Manual. The CTM performs most of the typical functions a Body Control Module would perform. The Highline CTM provides the following features: Remote Keyless Entry (RKE) - Chime - Courtesy Lamp Controls/Illuminated Entry - Power Door Locks - Speed Sensitive Intermittent Wipers - Enhanced Accident Response - Vehicle Theft Security System (VTSS) The module is located on the right side of the glove box behind a metal bracket. It contains a white 18-way and a green 14-way connector. CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODES Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure DESCRIPTION Two versions of the Central Timer Module (CTM) are available on this vehicle, a base version and a high-line version. The base version of the CTM is used on base models of the vehicle. The base version of the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, and an ignition lamp time delay relay in a single unit. The high-line version of the CTM is used on highline vehicles. The high-line CTM provides all of the functions of the base version CTM, but also is used to control and integrate many of the additional electronic functions and features included on the high-line models. The high-line version of the CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, reduce internal controller hardware, and reduce component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many new feature capabilities. One of the functions and features that both versions of the CTM support is the chime warning system. The CTM contains a chime tone generator to perform the functions of the chime warning module. The CTM uses hard-wired switch inputs, internal programming, and a hard-wired chime request input from the instrument cluster circuitry to detect when a chime tone is required. Both versions of the CTM are mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening. For diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The high-line Central Timer Module (CTM) can also control some features of the audio system when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The RAZ radio receiver with a remote radio switch option is one of the features that the CTM controls. The CTM is programmed to send switch status messages over the Chrysler Collision Detection (CCD) data bus to control the volume, seek, and pre-set station advance functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch status messages to the radio receiver. The electronic circuitry within the radio receiver responds to the switch status messages it receives by adjusting the radio settings as requested. Refer to Remote Radio Switch in the Description and Operation for more information on this component. In addition, radio receivers connected to the CCD data bus have several audio system functions that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more information on DRB testing of the audio systems. The high-line Central Timer Module (CTM) can also operate the horn system. A high-line CTM is used on high-line versions of this vehicle.

The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The horn relay is one of the hard wired outputs of the CTM. The high-line CTM is programmed to energize or deenergize the horn relay in response to certain inputs from the Remote Keyless Entry (RKE) system and/or the Vehicle Theft Security System (VTSS). Refer to Remote Keyless Entry System Description. Refer to Vehicle Theft Security System Description for more information on the VTSS. Both the base and the high-line versions of the CTM support the intermittent wipe and wipe-after-wash features, but only the high-line CTM supports the speed sensitive intermittent wipe. The intermittent wipe relay is one of the outputs that both the base and the high-line versions of the CTM can control. Each CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the high-line CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The high-line CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The high-line CTM receives hard-wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch while the driver door is open if the key is in the ignition and/or the headlamps are on. However, the locks can still be operated manually, with a key, or energized with the RKE transmitter. - A Panic Mode feature which can provide additional personal security and protection. When the Panic button on the RKE transmitter is depressed the vehicle horn will pulse, the headlights will flash, and the interior lights will illuminate on the vehicle for about three minutes, or until the Panic button is depressed a second time. A vehicle speed of about 24 kilometers-per-hour (15 miles-per-hour) will also cancel the panic mode. - An enhanced accident response feature will unlock both doors, then prevent the power door locks from locking the doors for a predetermined time interval, after receiving a CCD message from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course, these responses are dependent upon functional battery power and wiring circuitry following the impact. - Rolling door locks is a programmable feature of the power lock system. This feature will automatically lock all of the doors after the vehicle reaches a speed of about 24 kilometers-per-hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour). - A programmable feature of the RKE system is the enabling or disabling of the horn chirp following activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the horn chirp duration (twenty or forty milliseconds) can be selected. One of the features that the high-line CTM supports and controls is the Vehicle Theft Security System (VTSS). In the VTSS, the CTM receives hard- wired inputs from the door jamb, door lock cylinder, and ignition switches. The programming in the CTM allows it to process the information from these inputs and send control outputs to energize or de-energize the headlamp relay, horn relay, and the security lamp. The CTM also sends CCD data bus messages to the Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS. The high-line CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry (RKE) systems, which are integrated into the arming, disarming, and triggering functions of the VTSS. The programmable features of the CTM can be enabled or disabled using the DRB scan tool as described in the proper Diagnostic Procedures. Refer to Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the highline version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. This information covers the diagnosis and service of only the hard-wired inputs used by the CTM to determine that a chime tone should be generated. See Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced.

The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 +12 chimes per minute for reminders and High; 180 + 12 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: Ignition off, key in ignition, driver's door open - Ignition off, headlamps on, driver's door open - Seat belt warning - Check engine lamp illuminated (after prove-out) - Airbag lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out if equipped) - Check gauges lamp illuminated - Low fuel warning lamp illuminated - Low washer fluid Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 1725 Central Timer Module ( CTM ) High Option: Description and Operation Airbag System AIRBAG SYSTEM The airbag system is designed to provide increased driver and passenger protection if the vehicle is involved in a front end collision. The system is most effective when used in conjunction with the seat belt system. The airbag control module (ACM) is an electronic module that monitors the airbag system for proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and contains the sensor and actuator that is responsible for airbag deployment. There are no external impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck at the bottom of the instrument panel. It is located forward of the console. The ACM provides diagnostic information (DTCs) to the technician through the DRB III(R) via the CCD bus.Some circuits are tested continuously; others are checked only under certain circumstances. The warning lamp is driven with messages relayed to the Mechanical Instrument Cluster (MIC) from the ACM via the CCD bus. The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be observed by the customer. Whenever the ignition key is turned to the "run" or "start" position,the airbag control module performs a lamp check by turning the AIRBAG warning lamp on for 6 - 8 seconds. If the lamp remains off, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains on, there could be an active fault in the system or the circuit that operates the lamp may be shorted to ground. If the lamp comes on and stays on for a period longer than 6-8 seconds, then goes off, there is usually an intermittent problem in the system. Perform the WARNING LAMP CIRCUIT OPEN procedure (refer to Testing and Inspection in this section) to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. Interior Lighting INTERIOR LIGHTING The courtesy lights are controlled by the CTM. The door switches are inputs to the CTM and the courtesy lights are outputs. The glove box lamp and the ash receiver lamp (if equipped) are not controlled by the CTM. They are hardwired to individual switches and fuses. The highline CTM also provides for illuminated entry option. If the CTM detects an unlock signal from the RKE transmitter, a door disarm switch input or the door jamb switch input, the interior courtesy lights will be turned on. The illuminated entry function is canceled if the CTM senses an ignition "on" condition or the "lock" command from a valid key fob If a door is left open or turned on by rotation of dimmer switch for more than fifteen minutes, the CTM will extinguish the lamps to avoid discharging the battery. If the lamps are turned on by courtesy lamp switch, the CTM will not be able to turn them off. Central Timer Module CENTRAL TIMER MODULE The Dakota (AN) utilizes a Central Timer Module (CTM). This system is available in a Base or Highline configuration. The Base CTM does not communicate on the CCD bus and will not be addressed. For concerns about the Base CTM, please refer to the appropriate Service Manual. The CTM performs most of the typical functions a Body Control Module would perform. The Highline CTM provides the following features: Remote Keyless Entry (RKE) - Chime - Courtesy Lamp Controls/Illuminated Entry - Power Door Locks - Speed Sensitive Intermittent Wipers - Enhanced Accident Response - Vehicle Theft Security System (VTSS) The module is located on the right side of the glove box behind a metal bracket. It contains a white 18-way and a green 14-way connector.

The base version of the CTM is used on base models of the vehicle. The base version of the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, and an ignition lamp time delay relay in a single unit. The high-line version of the CTM is used on highline vehicles. The high-line CTM provides all of the functions of the base version CTM, but also is used to control and integrate many of the additional electronic functions and features included on the high-line models. The high-line version of the CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, reduce internal controller hardware, and reduce component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many new feature capabilities. One of the functions and features that both versions of the CTM support is the chime warning system. The CTM contains a chime tone generator to perform the functions of the chime warning module. The CTM uses hard-wired switch inputs, internal programming, and a hard-wired chime request input from the instrument cluster circuitry to detect when a chime tone is required. Both versions of the CTM are mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening. For diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The high-line Central Timer Module (CTM) can also control some features of the audio system when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The RAZ radio receiver with a remote radio switch option is one of the features that the CTM controls. The CTM is programmed to send switch status messages over the Chrysler Collision Detection (CCD) data bus to control the volume, seek, and pre-set station advance functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch status messages to the radio receiver. The electronic circuitry within the radio receiver responds to the switch status messages it receives by adjusting the radio settings as requested. Refer to Remote Radio Switch in the Description and Operation for more information on this component. In addition, radio receivers connected to the CCD data bus have several audio system functions that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more information on DRB testing of the audio systems. The high-line Central Timer Module (CTM) can also operate the horn system. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The horn relay is one of the hard wired outputs of the CTM. The high-line CTM is programmed to energize or deenergize the horn relay in response to certain inputs from the Remote Keyless Entry (RKE) system and/or the Vehicle Theft Security System (VTSS). Refer to Remote Keyless Entry System Description. Refer to Vehicle Theft Security System Description for more information on the VTSS. Both the base and the high-line versions of the CTM support the intermittent wipe and wipe-after-wash features, but only the high-line CTM supports the speed sensitive intermittent wipe. The intermittent wipe relay is one of the outputs that both the base and the high-line versions of the CTM can control. Each CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the high-line CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The high-line CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The high-line CTM receives hard-wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 1727 programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch while the driver door is open if the key is in the ignition and/or the headlamps are on.

Chime System CHIME SYSTEM The chime system is built into the CTM. The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 +12 chimes per minute for reminders and High; 180 + 12 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: Ignition off, key in ignition, driver's door open - Ignition off, headlamps on, driver's door open - Seat belt warning - Check engine lamp illuminated (after prove-out) - Airbag lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out if equipped) - Check gauges lamp illuminated - Low fuel warning lamp illuminated - Low washer fluid Compass Mini-Trip Computer (CMTC) COMPASS MINI-TRIP COMPUTER (CMTC) This system, located in the overhead console, displays information on outside temperature, compass direction and trip information. Compass And Temperature Display This display provides the outside temperature and one of eight compass readings to indicate the direction the vehicle is facing. Trip Odometer (ODO) Shows the distance traveled since the last reset. Average Fuel Economy (AVE ECO) Shows the average fuel economy in MPG (miles per gallon) or L/100Km since the last reset. Instantaneous Fuel Economy Shows the fuel economy for the last few seconds in MPG or L/100Km. Distance to Empty (DTE) Shows the estimated distance that can be traveled with the fuel remaining in the tank. This is calibrated using the MPG for the last few minutes. Elapsed Time (ET) Shows the accumulated ignition on time since the last reset. Step Button Press this button to cycle through all the mini-trip computer displays. US/M Button Press this button to convert all vehicle displays from US to Metric to US. To Reset the Display Press the Step and US/M buttons simultaneously for at least two seconds and all resettable conditions will be reset. This will occur only if a resettable function (AVG ECO,Trip Odometer, ET) is currently being displayed. Automatic Compass Calibration This compass is self calibrating which eliminates the need to manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL symbol will be displayed. After completing three 360' turns in an area free from large metal or metallic objects, the CAL symbol will turn off and the compass will function normally. Compass Variance Compass Variance is the difference between Magnetic North and Geographic North. In some areas of the country, the difference between Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 1729 Magnetic and Geographic North is great enough to cause the compass to give false readings. If this occurs, the compass vanance must be set. To set the variance: Turn the ignition ON and set display to Comp./Temp. While pressing the US/M button, press the STEP button for approximately five seconds. The "VAR" symbol will light and the last variance zone number will be displayed. Press the US/Metric Button to select the proper variance zone as shown on the map. Press the Step button to set the new variance zone and resume normal operation. Diagnostics DIAGNOSTICS The CTM is fully addressable with the DRB III(R) and it is the recommended method for diagnosis. The CTM reports 6 Diagnostic Trouble Codes. All of the inputs to the CTM can be read with the DRB and the outputs can be actuated. DRB III Error Messages and Blank Screen DRB III(R) ERROR MESSAGES AND BLANK SCREEN Under normal operation, the DRB will display one of only two error messages: User-Requested WARM Boot or User-Requested COLD Boot If the DRB should display any other error message, record the entire display an call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display: ver: 2.14 date: 26 Jul93 file: key itf.cc date: Jul 26 1993 line: 548 err: 0x1 User-Requested COLD Boot Press MORE to switch between this display and the application screen. Press F4 when done noting information. DRB III(R) does not power up (Blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRB may be the result of faulty cable or vehicle wiring. Perform the "Blank Screen" test under Testing and Inspection, Non-Diagnostic Trouble Codes in this section. Display is not visible Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition. Enhanced Accident Response (Highline CTM Only) ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned on when the vehicle speed message on the CCD bus indicates 0 mph or the message is not present. In addition to unlocking the doors, the door lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "off" position, normal operation will resume. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 1730 Glossary of Terms/Acronyms GLOSSARY OF ACRONYMS ACM airbag control module CCD Chrysler Collision Detection (vehicle communication bus) DAB driver airbag DLC data link connector EM entry module PAB passenger airbag PCM powertrain control module PDC power distribution center SQUIB also called indicator (located in rear of airbag module) Mechanical Instrument Cluster (MIC) MECHANICAL INSTRUMENT CLUSTER (MIC) The MIC is available in 4 different versions. Two of the versions are Canadian clusters. There is a highline and a low line cluster available. The difference is the addition of a tachometer in the highline. In order to accomplish this, the fuel level gauge is reduced in size and oil pressure gauge is relocated. The cluster positions it's gauges with bus messages received from the PCM. The odometer is a Liquid Crystal Display (LCD). The cluster will provide bus bias and the PCM provides termination. The MIC has an internal diagnostic routing that can be accessed by pushing and holding the trip odometer while rotating the key to the on position. The cluster will then place all the gauges at their calibration points and will light all the CCD driven tell-tales. It will also light all the segments of the LCD display for a visual verification check. The MIC can verify communications with the PCM, ID the module, or change the country code by using options 1, 3, or 9 on the DRB III(R) under the MIC menu. If there are faults found during the diagnostic routine, the cluster will report them on the LCD odometer display. For further information about the diagnostic routine and the explanation of the faults, please refer to Instrument Panel, Testing and Inspection. Power Door Lock System POWER DOOR LOCKS The CTM controls the door lock actuator assemblies to handle locking and unlocking with the key fob or interior switch. There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is off, the door is open, and the key is in the ignition. Automatic or "rolling locks" are included as a DRB III(R) or customer programmable feature. If the vehicle is moving approximately 15 mph and approximately 10 degrees of throttle opening is seen by the PCM, (the PCM will send this info to the CTM via the CCD bus) indicating acceleration, the CTM will cycle the lock actuators to lock the doors. Remote Keyless Entry (RKE) /Vehicle Theft Security System (VTSS) RKE/VTSS If the vehicle is equipped with Remote Keyless Entry (RKE), programming of additional transmitters and horn chirp are customer programmable features. The highline CTM provides for RKE and the Vehicle Theft Security System (VTSS). The base CTM is not able to provide these functions. The presence of either of these options dictates that the vehicle is equipped with a highline CTM. The VTSS system monitors the door ajar switches and ignition switch to detect unauthorized entry into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to start the engine, it will start and stall, If the trigger condition is still present, the lights will continue to flash for an additional 15 minutes After 15 minutes the system will stop pulsing the lights and return to the "armed" state.The cause of the last 4 alarm triggers is stored by the CTM and may be retrieved by the DRB III(R).The system may be disarmed by either an unlock command from a valid RKE key fob or by using a key in either door. Both front door key cylinders are equipped with disarm switches. There is also a VTSS lamp on the dash that provides information to the driver about the state of the vehicle theft system. The RKE system is placed in the programming mode by the DRB III(R), or by using the customer programming sequence. The system will store up to four key fob codes. Two fobs are supplied with the truck, additional fobs may be purchased through parts department. The additional fobs can be programmed with the DRB III(R), or by using the customer programming sequence. Through the DRB III(R), erasing and programming of one key fob without deleting the others is possible. If the key fob is stolen, all the fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense of security.

There are two additional modules, the Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are performed through the Serial Communication Interface of SCI, the same as previous years. All of the information about the functioning of all the systems is organized controlled, and communicated by the CCD bus, which is described in (CCD Bus) of this general information. Through the CCD bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require all the information to perform it's function. It will only respond to messages "addressed" to it through a binary coding process. This method of data transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. Airbag Trouble Code Types and Descriptions AIRBAG DIAGNOSTIC TROUBLE CODES Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists,diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this book to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRB, The procedure begins with AIRBAG TEST 1A-Identifying Airbag System Problems. This will direct you to the specific test(s) that must be performed. Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures, diagnostic trouble codes are used as a diagnostic tool. Active Codes The code becomes active as soon as the malfunction is detected and stored after one minutes of occurrence or key-off, whichever occurs first. An active trouble code indicates an on-going malfunction. This means that the defect is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present. Stored Codes Airbag codes are automatically stored in the ACM's memory after one minute of occurrence or when the ignition is turned off. The exception is the "Loss of Ignition Run Only" code which is an active code only. A "stored" code indicates there was an active code present at some time. However, the code currently may not be present as an active code, although another active code could be. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 1732 If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem. In this case, the stored code can indicate an area to inspect. If no obvious problems are found, erase stored codes, and with the "on" wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is difficult to locate. Airbag Diagnostic Trouble Codes The airbag control module may report any of the following diagnostic trouble codes. For the following codes, replace the Airbag Control Module (ACM) even if set intermittently: ACM Accelerometer - Internal Diagnostic 1 - Internal Diagnostic 2 For the following codes, replace the airbag control module (ACM): ACM Output Driver - ACM Stored Energy Logic - ACM Stored Energy Driver - ACM Stored Energy Passenger - Internal Diagnostic 3 - Internal Diagnostic 4 - Safing Sensor Shorted - Warning Lamp Driver Error For these codes, refer to the appropriate diagnostic procedure: Driver Squib Open Driver Squib Shorted Loss of Ignition Run Only Loss of Ignition Run/Start No CCD Communication Passenger Squib Circuit Open Passenger Squib Circuit Shorted Either Squib Terminal Short to Battery Either Squib Terminal Short to Ground Warning Lamp Circuit Open Warning Lamp Circuit Shorted Central Timer Module Diagnostic Trouble Codes CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODES Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure Vehicle Communication VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the highest priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a "voltage divider network" located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems may use more than one. Some modules are capable of both biasing and terminating. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. In this vehicle, the bias is supplied by the instrument cluster and termination is provided by the PCM and the instrument cluster. Without termination,voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLE'S ON-BOARD Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 1733 DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING. IF THERE IS A PROBLEM, REFER TO TESTING AND INSPECTION IN THIS SECTION. BUS FAILURE MESSAGES Short to Battery - Either or both of the bus wires are shorted to the battery potential. Or open ground to any CCD bus module. Short to 5 Volts - Either or both of the bus wires are shorted to a 5 volt potential. Short to Ground - Either or both of the bus wires are shorted to ground. Bus (+) & (-) Shorted Together - The two bus wires are shorted together. No Termination - The bus system has lost connection with all of its terminators. Bus Bias Level Too Low - Either or both of the bus wire potentials are significantly below their normal 2.5 volts. Bus Bias Level Too High - Either or both of the bus wire potentials are significantly above their normal 2.5 volts. No Bus Bias - The bus system has lost connection with Instrument Cluster. Bus (+) Open - The bus (+) wire has lost connection with termination and/or bias. Bus (-) Open - The bus (-) wire has lost connection with termination and/or bias. Not Receiving Bus Messages Correctly - The DRB cannot communicate over the bus and does not know why. Warnings WARNINGS Vehicle Damage Warnings Before disconnecting any control module, make sure the ignition is "off". Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side(not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. Road testing a complaint vehicle Some of the complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition. CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE REASSEMBLED. DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION. DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR OPERATE IT YOURSELF. HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB. Wiper System SPEED SENSITIVE INTERMITTENT WIPERS The AN truck equipped with a highline CTM will utilize speed sensitive intermittent wipers. Only a highline CTM will be able to support this feature. A base CTM will provide for intermittent wipers without the speed sensitive feature. The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, an immediate wipe of the windshield takes place and the new delay interval is implemented. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Testing and Inspection > Reading and Clearing Diagnostic Trouble Codes Central Timer Module ( CTM ) High Option: Reading and Clearing Diagnostic Trouble Codes With Scan Tool Data Link (Diagnostic) Connector Location Technicians must retrieve stored DTC's by connecting the DRB scan tool (or an equivalent scan tool) to the 16-way data link connector.

In addition, for 2000 M.Y. vehicles equipped with a 46RE transmission this bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 00Cal13/13A). MODELS: 2000 (AB) Ram Van 1999 - 2000 (AN) Dakota 1999 - 2000 (BR/BE) Ram Truck 2000 (DN) Durango 1999 - 2000 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO 1999 AND 2000 MODEL YEAR VEHICLES EQUIPPED WITH EITHER A 42RE AUTOMATIC TRANSMISSION BUILT BEFORE SEPTEMBER 1, 1999 (MDH 0901 XX) OR 2000 MODEL YEAR VEHICLES EQUIPPED WITH A 46RE AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 1,1999 (MDH I2OIXX). SYMPTOM/CONDITION: The customer may experience a harsh engagement into gear when reverse is selected. This condition may be intermittent, and may occur more frequently as the transmission fluid warms to normal operating temperatures. DIAGNOSIS: 1. Verify that the transmission fluid level is correct. 2. Verify that the valve body throttle valve and transmission shift linkage is adjusted properly. Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III) with the appropriate Diagnostic Procedures Manual, verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptoms have been experienced, perform the Repair Procedure. NOTE: WHENEVER A POWERTRAIN CONTROL MODULE (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION LEVEL. USE THE FLASH PROCEDURE TO UPDATE REPLACED CONTROLLERS AS NECESSARY.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1795 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1796 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1797 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1798 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1799 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1800 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number for the subsequent diagram will match a listed group shown. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1801 Connector and Terminal Replacement 1.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1810 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1811 3.

Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1812 Powertrain Control Module: Connector Views Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 1813 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Page 1814 Powertrain Control Module: Description and Operation Powertrain Control Module (PCM) The Powertrain Control Module (PCM) is located in the engine compartment. The ignition system is controlled by the PCM. NOTE: Base ignition timing by rotation of distributor is not adjustable on any of these engines. The PCM opens and closes the ignition coil ground circuit to operate the ignition coil. This is done to adjust ignition timing, both initial (base) and advance, and for changing engine operating conditions. The amount of electronic spark advance provided by the PCM is determined by five input factors: engine coolant temperature, engine rpm, intake manifold temperature, manifold absolute pressure and throttle position. Speed Control Operation The speed control electronic control circuitry is integrated into the PCM. The PCM speed control functions are monitored by the On-Board Diagnostics (OBD). All OBD-sensed systems are monitored by the PCM. Each monitored circuit is assigned a Diagnostic Trouble Code (DTC). The PCM will store a DTC in electronic memory for certain failures it detects. See On-Board Diagnostic Test For Speed Control System for more information. The PCM cannot be repaired and must be replaced if faulty. PCM Control of Automatic Transmission The PCM controls operation of the converter clutch, overdrive clutch, and governor pressure solenoid. The control module determines transmission shift points based on input signals from the transmission thermistor, transmission output shaft speed sensor, crankshaft position sensor, vehicle speed sensor, throttle position sensor, and battery temperature sensor. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Page 1815 Powertrain Control Module: Service and Repair PCM Location And Mounting The PCM is located in the engine compartment. REMOVAL To avoid possible voltage spike damage to the PCM, ignition key must be off, and negative battery cable must be disconnected before unplugging PCM connectors. 1. Disconnect negative battery cable at battery. 2. Remove cover over electrical connectors. Cover snaps onto PCM. 3. Carefully unplug the three 32-way connectors from PCM. 4. Remove three PCM mounting bolts and remove PCM from vehicle. INSTALLATION 1. Install PCM and mounting bolts to vehicle. 2. Tighten bolts to 3-5 N-m (30-40 in. lbs.). 3.

The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Camshaft Position Sensor-Typical (Distributor Shown) CAMSHAFT POSITION SENSOR-PCM INPUT A sync signal is provide by the camshaft position sensor. The sensor located in the distributor on all engines. The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs.

To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain Diagnostics Procedures service manual. To test the sensor only, refer to the following: For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips. 1. Connect the positive (+) voltmeter lead into the sensor output wire. This is at done the distributor wire harness connector. 2. Connect the negative (-) voltmeter lead into the ground wire. 3. Set the voltmeter to the 15 Volt DC scale. 4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup. 5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 6. If voltage is not present, check the voltmeter leads for a good connection. 7. If voltage is still not present, check for voltage at the supply wire. 8. If 5 volts is not present at supply wire, check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for this test. 9. If voltage is still not present, perform vehicle test using the DRB scan tool. 10. If voltage is present at cavity A-17, but not at the supply wire: a. Check continuity between the supply wire. This is checked between the distributor connector and cavity A-17 at the PCM. If continuity is not present, repair the harness as necessary. b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the PCM. If continuity is not present, repair the harness as necessary. c. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary. 11. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. If sync pulse signal is not present, replacement of the camshaft position sensor is necessary. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Camshaft Position Sensor > Component Information > Locations > Page 1862 Camshaft Position Sensor: Service and Repair Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines.

The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing. The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it. Sensor Operation The flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its outer edge. The notches cause a pulse to be generated when they pass under the sensor. The pulses are the input to the PCM. For each engine revolution, there are 8 pulses generated. The engine will not operate if the PCM does not receive a crankshaft position sensor input. CRANKSHAFT POSITION SENSOR-PCM INPUT This sensor is a hall effect device that detects notches in the flywheel (manual transmission) or flexplate (automatic transmission). This sensor is used to indicate to the powertrain control module (PCM) that a spark and or fuel injection event is to be required. The output from this sensor, in conjunction with the camshaft position sensor signal, is used to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders.

They are: Left, right, pre-catalyst and post catalyst. The left, right and post catalyst sensors will fine-tune air-fuel ratio. The pre-catalyst and post catalyst sensors will determine catalytic converter efficiency. Two of these sensors are installed into the left and right exhaust manifold downpipes. The left O2S sensor will monitor cylinders 1, 3, 5 and 7. The right sensor will monitor cylinders 2, 4, 6 and 8. The sensors produce voltages from 0 to 1 volt, depending upon the oxygen content of the exhaust gas in the exhaust manifold. When a large amount of oxygen is present (caused by a lean air/fuel mixture), the sensors produces a low voltage. When there is a lesser amount present (rich air/fuel mixture) it produces a higher voltage. By monitoring the oxygen content and converting it to electrical voltage, the sensors act as a rich-lean switch. The oxygen sensors are equipped with a heating element that keeps the sensors at proper operating temperature during all operating modes. Maintaining correct sensor temperature at all times allows the system to enter into closed loop operation sooner. Also, it allows the system to remain in closed loop operation during periods of extended idle. In Closed Loop operation, the PCM monitors the O2S sensor input (along with other inputs) and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values and inputs from other sensors. The Automatic Shutdown (ASD) relay supplies battery voltage to both oxygen sensors. The oxygen sensors are equipped with a heating elements. The heating elements reduce the time required for the sensors to reach operating temperature. PRE-CATALYST OXYGEN SENSOR The pre-catalyst O2S sensor is located in the inlet end of the catalytic converter. It provides an input voltage to the PCM. By comparing the input from the pre-catalyst O2S sensor, with the input from the post catalyst oxygen sensor, the PCM calculates catalytic convertor efficiency. POST CATALYST OXYGEN SENSOR The post catalyst heated oxygen sensor threads into the outlet end of the catalytic convertor. The post catalyst heated oxygen sensor input is used to detect catalytic convertor deterioration and fine tune the air fuel ratio. As the convertor deteriorates, the input from this sensor begins to match the pre-catalyst sensor input except for a slight time delay. By comparing the inputs from both of these sensors, the PCM calculates catalytic convertor efficiency. When the catalytic converter efficiency drops below emission standards, the PCM stores a diagnostic trouble code and illuminates the Malfunction Indicator Lamp (MIL). For more information, refer to Emission Control Systems. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Page 1918 Oxygen Sensor: Testing and Inspection To perform a complete test of the O2S sensors and their circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Throttle Position Sensor > Component Information > Specifications > Page 1930 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1943 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1944 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1945 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1946 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1947 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 1960 Connector Pin Identification Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Page 1961 Vehicle Speed Sensor: Description and Operation VEHICLE SPEED AND DISTANCE-PCM INPUT Vehicle speed and distance covered are measured by the Rear Wheel Speed Sensor.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 1969 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures.

The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Camshaft Position Sensor-Typical (Distributor Shown) CAMSHAFT POSITION SENSOR-PCM INPUT A sync signal is provide by the camshaft position sensor. The sensor located in the distributor on all engines. The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Locations > Page 1977 Camshaft Position Sensor: Testing and Inspection Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines. To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain Diagnostics Procedures service manual. To test the sensor only, refer to the following: For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips. 1. Connect the positive (+) voltmeter lead into the sensor output wire. This is at done the distributor wire harness connector. 2. Connect the negative (-) voltmeter lead into the ground wire. 3. Set the voltmeter to the 15 Volt DC scale. 4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup. 5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 6. If voltage is not present, check the voltmeter leads for a good connection. 7. If voltage is still not present, check for voltage at the supply wire. 8. If 5 volts is not present at supply wire, check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for this test. 9. If voltage is still not present, perform vehicle test using the DRB scan tool. 10. If voltage is present at cavity A-17, but not at the supply wire: a. Check continuity between the supply wire. This is checked between the distributor connector and cavity A-17 at the PCM. If continuity is not present, repair the harness as necessary. b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the PCM. If continuity is not present, repair the harness as necessary. c. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary. 11. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. If sync pulse signal is not present, replacement of the camshaft position sensor is necessary. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Sensors and Switches - Powertrain Management > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Locations > Page 1978 Camshaft Position Sensor: Service and Repair Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines.

It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: - Fuel pressure bleeding past a fuel injector(s). - Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose. Tool number 6539 is used for 5/16" fuel lines and tool number 6631 is used for 3/8" fuel lines. Connecting Adapter Tool-Typical Connecting Adapter Tool-Typical 3. Connect correct Fuel Line Pressure Test Adapter Tool Hose between disconnected fuel line and fuel rail. 4. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Fuel Pressure > System Information > Specifications > Page 2003 6. Observe test gauge. Normal operating pressure should be 339 kPa ± 34 kPa (49.2 psi ± 5 psi). 7. Shut engine off. 8. Pressure should not fall below 30 psi for five minutes. 9. If pressure falls below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine off. 12. Testing for fuel injector or fuel rail leakage: Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking. 13. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage: Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line. If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump or filter/regulator may be leaking. Note: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A slow loss of pressure usually indicates a defective check valve in the electric fuel pump. The electric fuel pump is not serviced separately. Replace the fuel pump module assembly. The filter/ regulator may be replaced separately on certain applications. Refer to Fuel Filter/Fuel Pressure Regulator Removal/installation for additional information. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Idle Speed > System Information > Specifications Idle Speed: Specifications Minimum Air Flow Idle ......................................................................................................................... ......................................................... 500 to 900 rpm Note: Idle speed range achieved through Minimum Air Flow Idle Test Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Idle Speed > System Information > Specifications > Page 2007 Idle Speed: Testing and Inspection The following test procedure has been developed to check throttle body calibrations for correct idle conditions.

Remove any slack in the No.4 cylinder plug wire between the three-wire and the five-wire clips. NOTE: EARLIER MODEL FIVE-WIRE CLIPS LOOK SLIGHTLY DIFFERENT BUT THE SAME WIRING LAYOUT APPLIES. D. Route the No.4 cylinder plug wire behind the transmission dipstick tube and heater hoses. On ZJ models this may not be possible due to the location of the bulkhead. NOTE: MAKE SURE THAT THE NO.4 CYLINDER PLUG WIRE IS, AT LEAST ONE INCH AWAY FROM THE NO.8 CYLINDER PLUG WIRE. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Ignition Cable: > 18-48-98 > Dec > 98 > Ignition System - Cross Fire/Ignition Wire Induction > Page 2046 E. Install the No.4 cylinder plug wire to its distributor cap terminal (Figure 7). 4. No.7 Cylinder Plug Wire Routing (Figure 8 and 9) A. Verify that the No.7 cylinder plug wire crosses over the distributor cap and leaves the distributor cap between the No.3 and the No.6 tower terminals (Figure 8). This is the original wire routing for 1998 and prior model years. B. For 1999 M.Y. vehicles the No.7 cylinder plug wire was shortened. Reroute the No.7 cylinder plug wire so that it crosses the distributor cap and leaves the distributor cap between the No.6 and the No.5 tower terminals (Figure 9). NOTE: MAKE SURE THE NO.7 CYLINDER PLUG WIRE IS, AT LEAST ONE INCH, AWAY FROM THE NO.5 CYLINDER PLUG WIRE. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Ignition Cable: > 18-48-98 > Dec > 98 > Ignition System - Cross Fire/Ignition Wire Induction > Page 2047 5. No. 5 Cylinder Plug Wire Routing (Figure 10) A. Remove the No.5 cylinder plug wire from its distributor cap terminal. B. Remove the No.5 cylinder plug wire from the five-wire clip located at the lower rear of the left valve cover. C. Route the No.5 cylinder plug wire over the left valve cover and in front of the breather tube elbow. D. Position the original convolute from the No.5 cylinder plug wire to prevent chafing against the valve cover and any engine components. Secure the small end of the hose to wire clip p/n 06503441 over the convolute. Secure the large end of the hose to wire clip to the breather hose.

Coil Wire Routing (Figure 11 and 12) A. Remove the coil wire from the distributor cap tower terminal. B. Remove the coil wire from the right rear five-wire clip, the center three wire clip and the front one-wire clip on the right valve cover. C. Install three (3) one-wire clips p/n 56028186 along the top and front of the valve cover studs (Figure 11). D. Route the coil wire starting from the ignition coil toward the distributor. Any excess wire should end up at the distributor end. E. Install the coil wire into the one-wire clips. This procedure may be easier to perform while the coil wire is loose from the valve cover (before the one-wire clips are attached to the valve cover studs). F. Cut the ignition wire convolute p/n 04364375 into three lengths. Two (2) at 101.5 mm (4 in.), and one (1) at 82.5 mm (3.25 in.). G. Slit and install the three sections of convolute onto the coil wire between the one-wire clips. Install the 82.5 mm (3.25 in.) section at the front of the right valve cover. Install the two 101.5 mm (4 in.) sections along the top side of the right valve cover. This procedure may be easier to perform while the coil wire is loose from the valve cover (before the clips are attached to the valve cover studs). H. Route the distributor end of the coil wire down and behind the intake manifold, in front of the oil pressure switch (Figure 12). NOTE: THE COIL WIRE MUST BE A MINIMUM OF ONE (1) INCH AWAY FROM ANY OTHER IGNITION WIRES. THIS MAY REQUIRE THAT THE COIL WIRE BE ROUTED UNDER VACUUM ANDIOR WIRE HARNESSES IN THE RIGHT REAR CORNER OF THE INTAKE MANIFOLD. Route the distributor end of the coil wire up the side of the distributor cap and onto the coil wire tower terminal. J. Position the original piece of coil wire convolute so it protects the wire against chafing with components at the rear of the engine. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 2049 Ignition Cable: Specifications Spark Plug Cable Resistance Minimum 250 ohms 3000 ohms Maximum 1000 ohms 12,000 ohms Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 2050 Ignition Cable: Description and Operation Spark plug cables are sometimes referred to as secondary ignition wires. These cables transfer electrical current from the ignition coil(s) and/or distributor, to individual spark plugs at each cylinder. The resistive spark plug cables are of nonmetallic construction. The cables provide suppression of radio frequency emissions from the ignition system. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 2051 Ignition Cable: Testing and Inspection Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and spark plugs. Terminals should be fully seated. The insulators should be in good condition and should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are cracked or torn must be replaced. Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the cables dry. Check for brittle or cracked insulation. Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable boot and spark plug. These shields protect the spark plug boots from damage (due to intense engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat shield. Testing When testing secondary cables for damage with an oscilloscope, follow the instructions of the equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as follows: CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during testing. This may cause possible heat damage to the catalytic converter. Total test time must not exceed ten minutes. With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to a good engine ground. If the cable and spark plug are in good condition, the engine rpm should drop and the engine will run poorly. If engine rpm does not drop, the cable and/or spark plug may not be operating properly and should be replaced. Also check engine cylinder compression. With the engine not running, connect one end of a test probe to a good ground. Start the engine and run the other end of the test probe along the entire length of all spark plug cables. If cables are cracked or punctured, there will be a noticeable spark jump from the damaged area to the test probe. The cable running from the ignition coil to the distributor cap can be checked in the same manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket. Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped, remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable. Test all spark plug cables in this manner. SPARK PLUG CABLE RESISTANCE MINIMUM = MAXIMUM 250 Ohms Per Inch = 1000 Ohms Per Inch 3000 Ohms Per Foot = 12,000 Ohms Per Foot To test ignition coil-to-distributor cap cable, do not remove the cable from the cap. Connect ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace the cable. Inspect the ignition coil tower for cracks, burns or corrosion. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Ignition Cable > Component Information > Technical Service Bulletins > Page 2052 Ignition Cable: Service and Repair REMOVAL AND INSTALLATION Cable Removal CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap, twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off with a steady, even force. Engine Firing Order Install cables into the proper engine cylinder firing order. When replacing the spark plug and coil cables, route the cables correctly and secure in the proper retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could also cause cross ignition of the plugs or short circuit the cables to ground. When installing new cables, make sure a positive connection is made. A snap should be felt when a good connection is made between the plug cable and the distributor cap tower. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Distributor, Ignition > Distributor Cap > Component Information > Testing and Inspection Distributor Cap: Testing and Inspection Cap Inspection - External - Typical Cap Inspection - Internal - Typical Remove the distributor cap and wipe it clean with a dry lint free cloth. Visually inspect the cap for cracks, carbon paths, broken towers or damaged rotor button. Also check for white deposits on the inside (caused by condensation entering the cap through cracks) Replace any cap that displays charred or eroded terminals. The machined surface of a terminal end (faces toward rotor) will indicate some evidence of erosion from normal operation. Examine the terminal ends for evidence of mechanical interference with the rotor tip. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Distributor, Ignition > Ignition Rotor > Component Information > Testing and Inspection Ignition Rotor: Testing and Inspection Rotor Inspection - Typical Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip. Also check for evidence of mechanical interference with the cap. Some charring is normal on the end of the metal tip. The silicone-dielectric-varnish-compound applied to the rotor tip for radio interference noise suppression, will appear charred. This is normal. Do not remove the charred corn- pound. Test the spring for insufficient tension. Replace a rotor that displays any of these adverse conditions. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications Spark Plug: Specifications Electrode Gap ...................................................................................................................................... ..................................................... 1.01 mm (0.040 in) Torque ............................................................ ............................................................................................................................................. 41 Nm (30 ft. lb.) Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2063 Spark Plug: Application and ID Plug Type ............................................................................................................................................ ....................................................................

Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in which they were removed from the engine. A single plug displaying an abnormal condition indicates that a problem exists in the corresponding cylinder. Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or oil fouled. Refer to the Spark Plug Condition. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2065 Spark Plug: Testing and Inspection SPARK PLUG CONDITIONS Normal Operation And Cold (Carbon) Fouling NORMAL OPERATING The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is evident with most grades of commercial gasoline. There will not be evidence of electrode burning. Gap growth will not average more than approximately 0.025 mm (0.001 in) per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the electrodes filed, have the gap set and then be installed. Some fuel refiners in several areas of the United States have introduced a manganese additive (MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits. COLD FOULING/CARBON FOULING Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be caused by a clogged air cleaner element or repeated short operating times (short trips). WET FOULING OR GAS FOULING A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the fouled plugs. Oil Or Ash Encrusted OIL OR ASH ENCRUSTED Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2066 If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of oil entry into that particular combustion chamber. Electrode Gap Bridging ELECTRODE GAP BRIDGING Electrode gap bridging may be traced to loose deposits in the combustion chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be cleaned using standard procedures. Scavenger Deposits SCAVENGER DEPOSITS Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is a normal condition caused by chemical additives in certain fuels. These additives are designed to change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in condition and can be cleaned using standard procedures. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2067 Chipped Electrode Insulator CHIPPED ELECTRODE INSULATOR A chipped electrode insulator usually results from bending the center electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation can also separate the insulator from the center electrode. Spark plugs with this condition must be replaced. Preignition Damage PREIGNITION DAMAGE Preignition damage is usually caused by excessive combustion chamber temperature. The center electrode dissolves first and the ground electrode dissolves somewhat latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine. Determine if ignition timing is over advanced or if other operating conditions are causing engine overheating. (The heat range rating refers to the operating temperature of a particular type spark plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon the thickness and length of the center electrodes porcelain insulator.) Spark Plug Overheating SPARK PLUG OVERHEATING Overheating is indicated by a white or gray center electrode insulator that also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug overheating. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2068 Spark Plug: Service and Repair Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each cable boot and spark plug. If removal of the heat shield(s) is necessary,remove the spark plug cable and compress the sides of shield for removal. Each shield is slotted to allow for compression and removal. To install the shields, align shield to machined opening in cylinder head and tap into place with a block of wood. PLUG REMOVAL Cable Removal 1. Always remove spark plug or ignition coil cables by grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady motion. Never pull directly on the cable. Internal damage to cable will result. 2. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area around the spark plug. This will help prevent foreign material from entering the combustion chamber. 3. Remove the spark plug using a quality socket with a rubber or foam insert. 4. Inspect the spark plug condition. Refer to Spark Plug Condition in the Diagnostics and Testing. PLUG CLEANING The plugs may be cleaned using commercially available spark plug cleaning equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before adjusting gap. CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will remain on the spark plug insulator and will cause plug misfire. PLUG GAP ADJUSTMENT Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug > Component Information > Specifications > Page 2069 Setting Spark Plug Gap - Typical Check the spark plug gap with a gap gauge tool. If the gap is not correct, adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center electrode. SPARK PLUG GAP 1.01 mm (0.040 in) PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged. Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator. When replacing the spark plug and ignition coil cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground. 1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark plugs to 35-41 N-m (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications Compression Check: Specifications Compression should not be less than 689 kPa (100 psi) and not vary more than 172 kPa (25 psi) from cylinder to cylinder. If cylinder(s) have abnormally low compression pressures, repeat procedure. - If the same cylinder(s) repeat an abnormally low reading, it could indicate the existence of a problem in the cylinder. NOTE: The recommended compression pressures are to be used only as a guide to diagnosing engine problems. An engine should NOT be disassembled to determine the cause of low compression unless some malfunction is present. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Compression Check > System Information > Specifications > Page 2073 Compression Check: Testing and Inspection The combustion pressure leakage test provides an accurate means for determining engine condition. Combustion pressure leakage testing will detect: ^ Exhaust and intake valve leaks (improper seating). ^ Leaks between adjacent cylinders or into water jacket. ^ Any causes for combustion/compression pressure loss. 1. Check the coolant level and fill as required. DO NOT install the radiator cap. 2. Start and operate the engine until it attains normal operating temperature, then turn the engine OFF. 3. Remove the spark plugs. 4. Remove the oil filler cap. 5. Remove the air cleaner. 6. Calibrate the tester according to the manufacturer's instructions. The shop air source for testing should maintain 483 kPa (70 psi) minimum, 1,379 kPa (200 psi) maximum and 552 kPa (80 psi) recommended. 7. Perform the test procedures on each cylinder according to the tester manufacturer's instructions. While testing, listen for pressurized air escaping through the throttle body, tailpipe and oil filler cap opening. Check for bubbles in the radiator coolant. All gauge pressure indications should be equal, with no more than 25% leakage. FOR EXAMPLE: At 552 kPa (80 psi) input pressure, a minimum of 414 kPa (60 psi) should be maintained in the cylinder.

A/C SELECT SIGNAL: When the A/C switch is in the ON position, an in put signal is sent to the powertrain control module (PCM). The signal informs the PCM that the A/C has been selected. The PCM adjusts idle speed to a pre-programmed rpm through the idle air control (IAC) motor to compensate for increased engine load. A/C REQUEST SIGNAL: Once A/C has been selected, the powertrain control module (PCM) receives the A/C request signal from the clutch cycling pressure switch. The input indicates that the evaporator pressure is in the proper range for A/C application. The PCM uses this input to cycle the A/C compressor clutch (through the A/C relay). It will also determine the correct engine idle speed through the idle air control (IAC) motor position. If the A/C low-pressure switch or high-pressure switch opens (indicating a low or high refrigerant pressure), the PCM will not receive an A/C request signal. The PCM will then remove the ground from the A/C relay. This will deactivate the A/C compressor clutch. If the switch opens, (indicating that evaporator is not in proper pressure range), the PCM will not receive the A/C request signal. The PCM will then remove the ground from the A/C relay, deactivating the A/C compressor clutch. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Intake Air Temperature Sensor > Component Information > Specifications Intake Air Temperature Sensor: Specifications Intake Manifold Temperature Sensor 28 Nm Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Intake Air Temperature Sensor > Component Information > Specifications > Page 2084 Intake Air Temperature Sensor: Locations Intake Manifold Air Temperature Sensor - Typical Intake Air Temperature Sensor, Engine Coolant Temparature Sensor Connector, Ignition Coil The intake manifold air temperature sensor is installed in the intake manifold with the sensor element extending into the air stream. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Intake Air Temperature Sensor > Component Information > Specifications > Page 2085 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Intake Air Temperature Sensor > Component Information > Specifications > Page 2086 Intake Air Temperature Sensor: Description and Operation Intake Manifold Air Temperature Sensor - Typical INTAKE MANIFOLD AIR TEMPERATURE SENSOR-PCM INPUT The intake manifold air temperature sensor is installed in the intake manifold with the sensor element extending into the air stream.

Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System Central Timer Module ( CTM ) High Option: Description and Operation Airbag System AIRBAG SYSTEM The airbag system is designed to provide increased driver and passenger protection if the vehicle is involved in a front end collision. The system is most effective when used in conjunction with the seat belt system. The airbag control module (ACM) is an electronic module that monitors the airbag system for proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and contains the sensor and actuator that is responsible for airbag deployment. There are no external impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck at the bottom of the instrument panel. It is located forward of the console. The ACM provides diagnostic information (DTCs) to the technician through the DRB III(R) via the CCD bus.Some circuits are tested continuously; others are checked only under certain circumstances. The warning lamp is driven with messages relayed to the Mechanical Instrument Cluster (MIC) from the ACM via the CCD bus. The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be observed by the customer. Whenever the ignition key is turned to the "run" or "start" position,the airbag control module performs a lamp check by turning the AIRBAG warning lamp on for 6 - 8 seconds. If the lamp remains off, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains on, there could be an active fault in the system or the circuit that operates the lamp may be shorted to ground. If the lamp comes on and stays on for a period longer than 6-8 seconds, then goes off, there is usually an intermittent problem in the system. Perform the WARNING LAMP CIRCUIT OPEN procedure (refer to Testing and Inspection in this section) to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2103 Central Timer Module ( CTM ) High Option: Description and Operation Interior Lighting INTERIOR LIGHTING The courtesy lights are controlled by the CTM.

This system is available in a Base or Highline configuration. The Base CTM does not communicate on the CCD bus and will not be addressed. For concerns about the Base CTM, please refer to the appropriate Service Manual. The CTM performs most of the typical functions a Body Control Module would perform. The Highline CTM provides the following features: Remote Keyless Entry (RKE) - Chime - Courtesy Lamp Controls/Illuminated Entry - Power Door Locks - Speed Sensitive Intermittent Wipers - Enhanced Accident Response - Vehicle Theft Security System (VTSS) The module is located on the right side of the glove box behind a metal bracket. It contains a white 18-way and a green 14-way connector. CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODES Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure DESCRIPTION Two versions of the Central Timer Module (CTM) are available on this vehicle, a base version and a high-line version. The base version of the CTM is used on base models of the vehicle. The base version of the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, and an ignition lamp time delay relay in a single unit. The high-line version of the CTM is used on highline vehicles. The high-line CTM provides all of the functions of the base version CTM, but also is used to control and integrate many of the additional electronic functions and features included on the high-line models. The high-line version of the CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, reduce internal controller hardware, and reduce component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many new feature capabilities. One of the functions and features that both versions of the CTM support is the chime warning system. The CTM contains a chime tone generator to perform the functions of the chime warning module. The CTM uses hard-wired switch inputs, internal programming, and a hard-wired chime request input from the instrument cluster circuitry to detect when a chime tone is required. Both versions of the CTM are mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening. For diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The high-line Central Timer Module (CTM) can also control some features of the audio system when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The RAZ radio receiver with a remote radio switch option is one of the features that the CTM controls. The CTM is programmed to send switch status messages over the Chrysler Collision Detection (CCD) data bus to control the volume, seek, and pre-set station advance functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch status messages to the radio receiver. The electronic circuitry within the radio receiver responds to the switch status messages it receives by adjusting the radio settings as requested. Refer to Remote Radio Switch in the Description and Operation for more information on this component. In addition, radio receivers connected to the CCD data bus have several audio system functions that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more information on DRB testing of the audio systems. The high-line Central Timer Module (CTM) can also operate the horn system. A high-line CTM is used on high-line versions of this vehicle. The Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2105 CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The horn relay is one of the hard wired outputs of the CTM. The high-line CTM is programmed to energize or deenergize the horn relay in response to certain inputs from the Remote Keyless Entry (RKE) system and/or the Vehicle Theft Security System (VTSS). Refer to Remote Keyless Entry System Description. Refer to Vehicle Theft Security System Description for more information on the VTSS. Both the base and the high-line versions of the CTM support the intermittent wipe and wipe-after-wash features, but only the high-line CTM supports the speed sensitive intermittent wipe. The intermittent wipe relay is one of the outputs that both the base and the high-line versions of the CTM can control. Each CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the high-line CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The high-line CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The high-line CTM receives hard-wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch while the driver door is open if the key is in the ignition and/or the headlamps are on. However, the locks can still be operated manually, with a key, or energized with the RKE transmitter. - A Panic Mode feature which can provide additional personal security and protection. When the Panic button on the RKE transmitter is depressed the vehicle horn will pulse, the headlights will flash, and the interior lights will illuminate on the vehicle for about three minutes, or until the Panic button is depressed a second time. A vehicle speed of about 24 kilometers-per-hour (15 miles-per-hour) will also cancel the panic mode. - An enhanced accident response feature will unlock both doors, then prevent the power door locks from locking the doors for a predetermined time interval, after receiving a CCD message from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course, these responses are dependent upon functional battery power and wiring circuitry following the impact. - Rolling door locks is a programmable feature of the power lock system. This feature will automatically lock all of the doors after the vehicle reaches a speed of about 24 kilometers-per-hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour). - A programmable feature of the RKE system is the enabling or disabling of the horn chirp following activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the horn chirp duration (twenty or forty milliseconds) can be selected. One of the features that the high-line CTM supports and controls is the Vehicle Theft Security System (VTSS). In the VTSS, the CTM receives hard- wired inputs from the door jamb, door lock cylinder, and ignition switches. The programming in the CTM allows it to process the information from these inputs and send control outputs to energize or de-energize the headlamp relay, horn relay, and the security lamp. The CTM also sends CCD data bus messages to the Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS. The high-line CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry (RKE) systems, which are integrated into the arming, disarming, and triggering functions of the VTSS. The programmable features of the CTM can be enabled or disabled using the DRB scan tool as described in the proper Diagnostic Procedures. Refer to Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the highline version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. This information covers the diagnosis and service of only the hard-wired inputs used by the CTM to determine that a chime tone should be generated.

The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 +12 chimes per minute for reminders and High; 180 + 12 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: Ignition off, key in ignition, driver's door open - Ignition off, headlamps on, driver's door open - Seat belt warning - Check engine lamp illuminated (after prove-out) - Airbag lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out if equipped) - Check gauges lamp illuminated - Low fuel warning lamp illuminated - Low washer fluid Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2108 Central Timer Module ( CTM ) High Option: Description and Operation Airbag System AIRBAG SYSTEM The airbag system is designed to provide increased driver and passenger protection if the vehicle is involved in a front end collision.

This feature allows the instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 +12 chimes per minute for reminders and High; 180 + 12 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: Ignition off, key in ignition, driver's door open - Ignition off, headlamps on, driver's door open - Seat belt warning - Check engine lamp illuminated (after prove-out) - Airbag lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out if equipped) - Check gauges lamp illuminated - Low fuel warning lamp illuminated - Low washer fluid Compass Mini-Trip Computer (CMTC) COMPASS MINI-TRIP COMPUTER (CMTC) This system, located in the overhead console, displays information on outside temperature, compass direction and trip information. Compass And Temperature Display This display provides the outside temperature and one of eight compass readings to indicate the direction the vehicle is facing. Trip Odometer (ODO) Shows the distance traveled since the last reset. Average Fuel Economy (AVE ECO) Shows the average fuel economy in MPG (miles per gallon) or L/100Km since the last reset. Instantaneous Fuel Economy Shows the fuel economy for the last few seconds in MPG or L/100Km. Distance to Empty (DTE) Shows the estimated distance that can be traveled with the fuel remaining in the tank. This is calibrated using the MPG for the last few minutes. Elapsed Time (ET) Shows the accumulated ignition on time since the last reset. Step Button Press this button to cycle through all the mini-trip computer displays. US/M Button Press this button to convert all vehicle displays from US to Metric to US. To Reset the Display Press the Step and US/M buttons simultaneously for at least two seconds and all resettable conditions will be reset. This will occur only if a resettable function (AVG ECO,Trip Odometer, ET) is currently being displayed. Automatic Compass Calibration This compass is self calibrating which eliminates the need to manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL symbol will be displayed. After completing three 360' turns in an area free from large metal or metallic objects, the CAL symbol will turn off and the compass will function normally. Compass Variance Compass Variance is the difference between Magnetic North and Geographic North. In some areas of the country, the difference between Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2112 Magnetic and Geographic North is great enough to cause the compass to give false readings. If this occurs, the compass vanance must be set. To set the variance: Turn the ignition ON and set display to Comp./Temp. While pressing the US/M button, press the STEP button for approximately five seconds. The "VAR" symbol will light and the last variance zone number will be displayed. Press the US/Metric Button to select the proper variance zone as shown on the map. Press the Step button to set the new variance zone and resume normal operation. Diagnostics DIAGNOSTICS The CTM is fully addressable with the DRB III(R) and it is the recommended method for diagnosis. The CTM reports 6 Diagnostic Trouble Codes. All of the inputs to the CTM can be read with the DRB and the outputs can be actuated. DRB III Error Messages and Blank Screen DRB III(R) ERROR MESSAGES AND BLANK SCREEN Under normal operation, the DRB will display one of only two error messages: User-Requested WARM Boot or User-Requested COLD Boot If the DRB should display any other error message, record the entire display an call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display: ver: 2.14 date: 26 Jul93 file: key itf.cc date: Jul 26 1993 line: 548 err: 0x1 User-Requested COLD Boot Press MORE to switch between this display and the application screen. Press F4 when done noting information. DRB III(R) does not power up (Blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRB may be the result of faulty cable or vehicle wiring. Perform the "Blank Screen" test under Testing and Inspection, Non-Diagnostic Trouble Codes in this section. Display is not visible Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition. Enhanced Accident Response (Highline CTM Only) ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned on when the vehicle speed message on the CCD bus indicates 0 mph or the message is not present. In addition to unlocking the doors, the door lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "off" position, normal operation will resume. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2113 Glossary of Terms/Acronyms GLOSSARY OF ACRONYMS ACM airbag control module CCD Chrysler Collision Detection (vehicle communication bus) DAB driver airbag DLC data link connector EM entry module PAB passenger airbag PCM powertrain control module PDC power distribution center SQUIB also called indicator (located in rear of airbag module) Mechanical Instrument Cluster (MIC) MECHANICAL INSTRUMENT CLUSTER (MIC) The MIC is available in 4 different versions. Two of the versions are Canadian clusters. There is a highline and a low line cluster available. The difference is the addition of a tachometer in the highline. In order to accomplish this, the fuel level gauge is reduced in size and oil pressure gauge is relocated. The cluster positions it's gauges with bus messages received from the PCM. The odometer is a Liquid Crystal Display (LCD). The cluster will provide bus bias and the PCM provides termination. The MIC has an internal diagnostic routing that can be accessed by pushing and holding the trip odometer while rotating the key to the on position. The cluster will then place all the gauges at their calibration points and will light all the CCD driven tell-tales. It will also light all the segments of the LCD display for a visual verification check. The MIC can verify communications with the PCM, ID the module, or change the country code by using options 1, 3, or 9 on the DRB III(R) under the MIC menu. If there are faults found during the diagnostic routine, the cluster will report them on the LCD odometer display. For further information about the diagnostic routine and the explanation of the faults, please refer to Instrument Panel, Testing and Inspection. Power Door Lock System POWER DOOR LOCKS The CTM controls the door lock actuator assemblies to handle locking and unlocking with the key fob or interior switch. There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is off, the door is open, and the key is in the ignition. Automatic or "rolling locks" are included as a DRB III(R) or customer programmable feature. If the vehicle is moving approximately 15 mph and approximately 10 degrees of throttle opening is seen by the PCM, (the PCM will send this info to the CTM via the CCD bus) indicating acceleration, the CTM will cycle the lock actuators to lock the doors. Remote Keyless Entry (RKE) /Vehicle Theft Security System (VTSS) RKE/VTSS If the vehicle is equipped with Remote Keyless Entry (RKE), programming of additional transmitters and horn chirp are customer programmable features. The highline CTM provides for RKE and the Vehicle Theft Security System (VTSS). The base CTM is not able to provide these functions. The presence of either of these options dictates that the vehicle is equipped with a highline CTM. The VTSS system monitors the door ajar switches and ignition switch to detect unauthorized entry into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to start the engine, it will start and stall, If the trigger condition is still present, the lights will continue to flash for an additional 15 minutes After 15 minutes the system will stop pulsing the lights and return to the "armed" state.The cause of the last 4 alarm triggers is stored by the CTM and may be retrieved by the DRB III(R).The system may be disarmed by either an unlock command from a valid RKE key fob or by using a key in either door. Both front door key cylinders are equipped with disarm switches. There is also a VTSS lamp on the dash that provides information to the driver about the state of the vehicle theft system. The RKE system is placed in the programming mode by the DRB III(R), or by using the customer programming sequence. The system will store up to four key fob codes. Two fobs are supplied with the truck, additional fobs may be purchased through parts department. The additional fobs can be programmed with the DRB III(R), or by using the customer programming sequence. Through the DRB III(R), erasing and programming of one key fob without deleting the others is possible. If the key fob is stolen, all the fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense of security.

There are two additional modules, the Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are performed through the Serial Communication Interface of SCI, the same as previous years. All of the information about the functioning of all the systems is organized controlled, and communicated by the CCD bus, which is described in (CCD Bus) of this general information. Through the CCD bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require all the information to perform it's function. It will only respond to messages "addressed" to it through a binary coding process. This method of data transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. Airbag Trouble Code Types and Descriptions AIRBAG DIAGNOSTIC TROUBLE CODES Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists,diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this book to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRB, The procedure begins with AIRBAG TEST 1A-Identifying Airbag System Problems. This will direct you to the specific test(s) that must be performed. Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures, diagnostic trouble codes are used as a diagnostic tool. Active Codes The code becomes active as soon as the malfunction is detected and stored after one minutes of occurrence or key-off, whichever occurs first. An active trouble code indicates an on-going malfunction. This means that the defect is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present. Stored Codes Airbag codes are automatically stored in the ACM's memory after one minute of occurrence or when the ignition is turned off. The exception is the "Loss of Ignition Run Only" code which is an active code only. A "stored" code indicates there was an active code present at some time. However, the code currently may not be present as an active code, although another active code could be. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2115 If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem. In this case, the stored code can indicate an area to inspect. If no obvious problems are found, erase stored codes, and with the "on" wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is difficult to locate. Airbag Diagnostic Trouble Codes The airbag control module may report any of the following diagnostic trouble codes. For the following codes, replace the Airbag Control Module (ACM) even if set intermittently: ACM Accelerometer - Internal Diagnostic 1 - Internal Diagnostic 2 For the following codes, replace the airbag control module (ACM): ACM Output Driver - ACM Stored Energy Logic - ACM Stored Energy Driver - ACM Stored Energy Passenger - Internal Diagnostic 3 - Internal Diagnostic 4 - Safing Sensor Shorted - Warning Lamp Driver Error For these codes, refer to the appropriate diagnostic procedure: Driver Squib Open Driver Squib Shorted Loss of Ignition Run Only Loss of Ignition Run/Start No CCD Communication Passenger Squib Circuit Open Passenger Squib Circuit Shorted Either Squib Terminal Short to Battery Either Squib Terminal Short to Ground Warning Lamp Circuit Open Warning Lamp Circuit Shorted Central Timer Module Diagnostic Trouble Codes CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODES Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure Vehicle Communication VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the highest priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a "voltage divider network" located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems may use more than one. Some modules are capable of both biasing and terminating. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. In this vehicle, the bias is supplied by the instrument cluster and termination is provided by the PCM and the instrument cluster. Without termination,voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLE'S ON-BOARD Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2116 DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING. IF THERE IS A PROBLEM, REFER TO TESTING AND INSPECTION IN THIS SECTION. BUS FAILURE MESSAGES Short to Battery - Either or both of the bus wires are shorted to the battery potential. Or open ground to any CCD bus module. Short to 5 Volts - Either or both of the bus wires are shorted to a 5 volt potential. Short to Ground - Either or both of the bus wires are shorted to ground. Bus (+) & (-) Shorted Together - The two bus wires are shorted together. No Termination - The bus system has lost connection with all of its terminators. Bus Bias Level Too Low - Either or both of the bus wire potentials are significantly below their normal 2.5 volts. Bus Bias Level Too High - Either or both of the bus wire potentials are significantly above their normal 2.5 volts. No Bus Bias - The bus system has lost connection with Instrument Cluster. Bus (+) Open - The bus (+) wire has lost connection with termination and/or bias. Bus (-) Open - The bus (-) wire has lost connection with termination and/or bias. Not Receiving Bus Messages Correctly - The DRB cannot communicate over the bus and does not know why. Warnings WARNINGS Vehicle Damage Warnings Before disconnecting any control module, make sure the ignition is "off". Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side(not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. Road testing a complaint vehicle Some of the complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition. CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE REASSEMBLED. DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION. DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR OPERATE IT YOURSELF. HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB. Wiper System SPEED SENSITIVE INTERMITTENT WIPERS The AN truck equipped with a highline CTM will utilize speed sensitive intermittent wipers. Only a highline CTM will be able to support this feature. A base CTM will provide for intermittent wipers without the speed sensitive feature. The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, an immediate wipe of the windshield takes place and the new delay interval is implemented. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Testing and Inspection > Reading and Clearing Diagnostic Trouble Codes Central Timer Module ( CTM ) High Option: Reading and Clearing Diagnostic Trouble Codes With Scan Tool Data Link (Diagnostic) Connector Location Technicians must retrieve stored DTC's by connecting the DRB scan tool (or an equivalent scan tool) to the 16-way data link connector.

The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Camshaft Position Sensor-Typical (Distributor Shown) CAMSHAFT POSITION SENSOR-PCM INPUT A sync signal is provide by the camshaft position sensor. The sensor located in the distributor on all engines. The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Locations > Page 2150 Camshaft Position Sensor: Testing and Inspection Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines. To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain Diagnostics Procedures service manual. To test the sensor only, refer to the following: For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips. 1. Connect the positive (+) voltmeter lead into the sensor output wire. This is at done the distributor wire harness connector. 2. Connect the negative (-) voltmeter lead into the ground wire. 3. Set the voltmeter to the 15 Volt DC scale. 4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup. 5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 6. If voltage is not present, check the voltmeter leads for a good connection. 7. If voltage is still not present, check for voltage at the supply wire. 8. If 5 volts is not present at supply wire, check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for this test. 9. If voltage is still not present, perform vehicle test using the DRB scan tool. 10. If voltage is present at cavity A-17, but not at the supply wire: a. Check continuity between the supply wire. This is checked between the distributor connector and cavity A-17 at the PCM. If continuity is not present, repair the harness as necessary. b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the PCM. If continuity is not present, repair the harness as necessary. c. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary. 11. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. If sync pulse signal is not present, replacement of the camshaft position sensor is necessary. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Camshaft Position Sensor > Component Information > Locations > Page 2151 Camshaft Position Sensor: Service and Repair Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines.

The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing. The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it. Sensor Operation The flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its outer edge. The notches cause a pulse to be generated when they pass under the sensor. The pulses are the input to the PCM. For each engine revolution, there are 8 pulses generated. The engine will not operate if the PCM does not receive a crankshaft position sensor input. CRANKSHAFT POSITION SENSOR-PCM INPUT This sensor is a hall effect device that detects notches in the flywheel (manual transmission) or flexplate (automatic transmission). This sensor is used to indicate to the powertrain control module (PCM) that a spark and or fuel injection event is to be required. The output from this sensor, in conjunction with the camshaft position sensor signal, is used to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2176 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2177 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2178 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2179 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2180 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2191 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2192 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 2193 Data Link Connector: Connector Views Connector Pin Identification Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector > Component Information > Diagrams > Page 2194 Data Link Connector: Description and Operation Data Link Connector Location DATA LINK CONNECTOR-PCM INPUT AND OUTPUT The 16-way data link connector (diagnostic scan tool connector) links the Diagnostic Readout Box (DRB) scan tool or the Mopar Diagnostic System (MDS) with the powertrain control module (PCM).

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2228 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2229 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2230 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2231 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2232 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2243 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2244 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2245 Powertrain Control Module: Connector Views Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2246 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Page 2247 Powertrain Control Module: Description and Operation Powertrain Control Module (PCM) The Powertrain Control Module (PCM) is located in the engine compartment. The ignition system is controlled by the PCM. NOTE: Base ignition timing by rotation of distributor is not adjustable on any of these engines. The PCM opens and closes the ignition coil ground circuit to operate the ignition coil. This is done to adjust ignition timing, both initial (base) and advance, and for changing engine operating conditions. The amount of electronic spark advance provided by the PCM is determined by five input factors: engine coolant temperature, engine rpm, intake manifold temperature, manifold absolute pressure and throttle position. Speed Control Operation The speed control electronic control circuitry is integrated into the PCM. The PCM speed control functions are monitored by the On-Board Diagnostics (OBD). All OBD-sensed systems are monitored by the PCM. Each monitored circuit is assigned a Diagnostic Trouble Code (DTC). The PCM will store a DTC in electronic memory for certain failures it detects. See On-Board Diagnostic Test For Speed Control System for more information. The PCM cannot be repaired and must be replaced if faulty. PCM Control of Automatic Transmission The PCM controls operation of the converter clutch, overdrive clutch, and governor pressure solenoid. The control module determines transmission shift points based on input signals from the transmission thermistor, transmission output shaft speed sensor, crankshaft position sensor, vehicle speed sensor, throttle position sensor, and battery temperature sensor. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Page 2248 Powertrain Control Module: Service and Repair PCM Location And Mounting The PCM is located in the engine compartment. REMOVAL To avoid possible voltage spike damage to the PCM, ignition key must be off, and negative battery cable must be disconnected before unplugging PCM connectors. 1. Disconnect negative battery cable at battery. 2. Remove cover over electrical connectors. Cover snaps onto PCM. 3. Carefully unplug the three 32-way connectors from PCM. 4. Remove three PCM mounting bolts and remove PCM from vehicle. INSTALLATION 1. Install PCM and mounting bolts to vehicle. 2. Tighten bolts to 3-5 N-m (30-40 in. lbs.). 3. Check pin connectors in the PCM and the three 32-way connectors for corrosion or damage. Repair as necessary. 4. Install three 32-way connectors. 5. Install cover over electrical connectors. Cover snaps onto PCM. 6. Install battery cable. 7. Use the DRB scan tool to reprogram new PCM with vehicles original Identification Number (VIN) and original vehicle mileage. If this step is not done, a Diagnostic Trouble Code (DTC) may be set. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Fuel Level Sensor > Component Information > Description and Operation Fuel Level Sensor: Description and Operation FUEL LEVEL SENSOR-PCM INPUT The Powertrain Control Module (PCM) supplies power to the fuel level sensor (fuel gauge sending unit). The fuel level sensor will then return a signal to the PCM to indicate fuel level. The purpose of this feature is to prevent a false setting of misfire and fuel system monitor trouble codes. This is if the fuel level is less than approximately 15 percent, or, if equipped with a Leak Detection Pump (LDP), more than approximately 85 percent of its rated capacity. This input is also used to send a signal to the PCM for fuel gauge operation via the CCD bus circuits. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Speed/Throttle Actuator Electronic > Component Information > Specifications Idle Speed/Throttle Actuator - Electronic: Specifications IAC Motor Mounting Bolts 7 Nm Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Speed/Throttle Actuator Electronic > Component Information > Specifications > Page 2255 Idle Speed/Throttle Actuator - Electronic: Locations MAP Sensor, Idle Air Control Motor, Throttle Position Sensor The IAC motor is mounted to the back of the throttle body Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Speed/Throttle Actuator Electronic > Component Information > Specifications > Page 2256 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Speed/Throttle Actuator Electronic > Component Information > Specifications > Page 2257 Idle Speed/Throttle Actuator - Electronic: Description and Operation IDLE AIR CONTROL (IAC) MOTOR-PCM OUTPUT The IAC motor is mounted to the back of the throttle body and is controlled by the powertrain control module (PCM). Throttle Body Air Control Passage The throttle body has an air control passage that provides air for the engine at idle (the throttle plate is closed). The IAC motor pintle protrudes into the air control passage and regulates air flow through it. Based on various sensor inputs, the powertrain control module (PCM) adjusts engine idle speed by moving the IAC motor pintle in and out of the air control passage. The IAC motor is positioned when the ignition key is turned to the On position. A (factory adjusted) set screw is used to mechanically limit the position of the throttle body throttle plate. Never attempt to adjust the engine idle speed using this screw. All idle speed functions are controlled by the PCM. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Speed/Throttle Actuator Electronic > Component Information > Specifications > Page 2258 Idle Speed/Throttle Actuator - Electronic: Testing and Inspection To perform a complete test of the IAC motor and its circuitry, refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Idle Speed/Throttle Actuator Electronic > Component Information > Specifications > Page 2259 Idle Speed/Throttle Actuator - Electronic: Service and Repair Mounting Bolts (Screws) - IAC Motor The IAC motor is located on the back of the throttle body.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2265 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2266 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2267 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2268 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2269 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2270 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2280 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2281 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Diagram Information and Instructions > Page 2282 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component Information > Diagrams > Page 2283 Information Bus: Description and Operation VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the highest priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a "voltage divider network" located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems may use more than one. Some modules are capable of both biasing and terminating. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. In this vehicle, the bias is supplied by the instrument cluster and termination is provided by the PCM and the instrument cluster. Without termination,voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned on when the vehicle speed message on the CCD bus indicates 0 mph or the message is not present. In addition to unlocking the doors, the door lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "off" position, normal operation will resume. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLE'S ON-BOARD DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING. IF THERE IS A PROBLEM, REFER TO BODY CONTROL MODULE, TESTING AND INSPECTION. BUS FAILURE MESSAGES Short to Battery - Either or both of the bus wires are shorted to the battery potential. Or open ground to any CCD bus module. Short to 5 Volts - Either or both of the bus wires are shorted to a 5 volt potential. Short to Ground - Either or both of the bus wires are shorted to ground. Bus (+) & (-) Shorted Together - The two bus wires are shorted together. No Termination - The bus system has lost connection with all of its terminators. Bus Bias Level Too Low - Either or both of the bus wire potentials are significantly below their normal 2.5 volts. Bus Bias Level Too High - Either or both of the bus wire potentials are significantly above their normal 2.5 volts. No Bus Bias - The bus system has lost connection with Instrument Cluster. Bus (+) Open - The bus (+) wire has lost connection with termination and/or bias. Bus (-) Open - The bus (-) wire has lost connection with termination and/or bias. Not Receiving Bus Messages Correctly - The DRB cannot communicate over the bus and does not know why. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations Automatic Shut Down (ASD) Relay: Locations 8w-10-2 The ASD relay is located in the Power Distribution Center (PDC). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations > Page 2287 Automatic Shut Down (ASD) Relay: Diagrams 8w-10-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations > Page 2288 8w-10-4 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations > Page 2289 Automatic Shut Down (ASD) Relay: Description and Operation As one of its functions, the ASD relay will supply battery voltage to the ignition coil, The ground circuit for the ASD relay is controlled by the Powertrain Control Module (PCM). The PCM regulates ASD relay operation by switching the ground circuit on-and-off. AUTOMATIC SHUTDOWN (ASD) RELAY SENSE-PCM INPUT Power Distribution Center (PDC) A 12 volt signal at this input indicates to the Powertrain Control Module (PCM) that the ASD has been activated. The ASD relay is located in the Power Distribution Center (PDC). The PDC is located in the engine compartment. Refer to label on PDC cover for relay location. The relay is used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt + power supply. This input is used only to sense that the ASD relay is energized. If the PCM does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic Trouble Code (DTC).

The ASD supplies battery voltage to the fuel injectors, ignition coil and oxygen (O2S) sensor heating elements. The ground circuit for the coil in the ASD relay is controlled by the powertrain control module (PCM). The PCM operates the relay by switching the ground circuit on and off. CCD BUS (+1-) CIRCUITS-PCM OUTPUTS The Powertrain Control Module (PCM) sends certain output signals through the CCD bus circuits. These signals are used to control certain instrument panel located items and to determine certain identification numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations > Page 2290 Automatic Shut Down (ASD) Relay: Testing and Inspection ASD And Fuel Pump Relay Terminals The following description of operation and tests apply only to the Automatic Shutdown (ASD) and fuel pump relays. The terminals on the bottom of each relay are numbered. Operation Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays, terminal 30 is connected to battery voltage at all times. - The PCM grounds the coil side of the relay through terminal number 85. - Terminal number 86 supplies voltage to the coil side of the relay. - When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the circuit. Terminal 87A is the center terminal on the relay. - When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30. This is the On position. Terminal 87 supplies voltage to the rest of the circuit. Testing The following procedure applies to the ASD and fuel pump relays. 1. Remove relay from connector before testing. 2. With the relay removed from the vehicle, use an ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75 ± 5 ohms. 3. Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity between terminals 30 and 87A. 4. Connect the ohmmeter between terminals 87 and 30. The ohmmeter should not show continuity at this time. 5. Connect one end of a jumper wire (16 gauge or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12 volt power source. 6. Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt power source. Do not attach the other end of the jumper wire to the relay at this time. WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS TEST. 7. Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The ohmmeter should now show continuity between relay terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and 30. 8. Disconnect jumper wires. 9. Replace the relay if it did not pass the continuity and resistance tests. If the relay passed the tests, it operates properly. Check the remainder of the ASD and fuel pump relay circuits. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Automatic Shut Down (ASD) Relay <--> [Main Relay (Computer/Fuel System)] > Component Information > Locations > Page 2291 Automatic Shut Down (ASD) Relay: Service and Repair Power Distribution Center (PDC) Location The ASD relay is located in the Power Distribution Center (PDC).

It provides an input voltage to the powertrain control module (PCM). As engine load changes, manifold pressure varies. The change in manifold pressure causes MAP sensor voltage to change. The change in MAP sensor voltage results in a different input voltage to the PCM. The input voltage level supplies the PCM with information about ambient barometric pressure during engine start-up (cranking) and engine load while the engine is running. The PCM uses this input along with inputs from other sensors to adjust air-fuel mixture. MAP And Throttle Position Sensor Location - Typical The MAP sensor is mounted on the side of the engine throttle body. The sensor is connected to the throttle body with a rubber L-shaped fitting. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Manifold Pressure/Vacuum Sensor > Component Information > Specifications > Page 2301 Manifold Pressure/Vacuum Sensor: Testing and Inspection MAP Sensor - Typical To perform a complete test of MAP sensor and its circuitry; refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures.

They are: Left, right, pre-catalyst and post catalyst. The left, right and post catalyst sensors will fine-tune air-fuel ratio. The pre-catalyst and post catalyst sensors will determine catalytic converter efficiency. Two of these sensors are installed into the left and right exhaust manifold downpipes. The left O2S sensor will monitor cylinders 1, 3, 5 and 7. The right sensor will monitor cylinders 2, 4, 6 and 8. The sensors produce voltages from 0 to 1 volt, depending upon the oxygen content of the exhaust gas in the exhaust manifold. When a large amount of oxygen is present (caused by a lean air/fuel mixture), the sensors produces a low voltage. When there is a lesser amount present (rich air/fuel mixture) it produces a higher voltage. By monitoring the oxygen content and converting it to electrical voltage, the sensors act as a rich-lean switch. The oxygen sensors are equipped with a heating element that keeps the sensors at proper operating temperature during all operating modes. Maintaining correct sensor temperature at all times allows the system to enter into closed loop operation sooner. Also, it allows the system to remain in closed loop operation during periods of extended idle. In Closed Loop operation, the PCM monitors the O2S sensor input (along with other inputs) and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values and inputs from other sensors. The Automatic Shutdown (ASD) relay supplies battery voltage to both oxygen sensors. The oxygen sensors are equipped with a heating elements. The heating elements reduce the time required for the sensors to reach operating temperature. PRE-CATALYST OXYGEN SENSOR The pre-catalyst O2S sensor is located in the inlet end of the catalytic converter. It provides an input voltage to the PCM. By comparing the input from the pre-catalyst O2S sensor, with the input from the post catalyst oxygen sensor, the PCM calculates catalytic convertor efficiency. POST CATALYST OXYGEN SENSOR The post catalyst heated oxygen sensor threads into the outlet end of the catalytic convertor. The post catalyst heated oxygen sensor input is used to detect catalytic convertor deterioration and fine tune the air fuel ratio. As the convertor deteriorates, the input from this sensor begins to match the pre-catalyst sensor input except for a slight time delay. By comparing the inputs from both of these sensors, the PCM calculates catalytic convertor efficiency. When the catalytic converter efficiency drops below emission standards, the PCM stores a diagnostic trouble code and illuminates the Malfunction Indicator Lamp (MIL). For more information, refer to Emission Control Systems. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Page 2321 Oxygen Sensor: Testing and Inspection To perform a complete test of the O2S sensors and their circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures.

Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System Central Timer Module ( CTM ) High Option: Description and Operation Airbag System AIRBAG SYSTEM The airbag system is designed to provide increased driver and passenger protection if the vehicle is involved in a front end collision. The system is most effective when used in conjunction with the seat belt system. The airbag control module (ACM) is an electronic module that monitors the airbag system for proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and contains the sensor and actuator that is responsible for airbag deployment. There are no external impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck at the bottom of the instrument panel. It is located forward of the console. The ACM provides diagnostic information (DTCs) to the technician through the DRB III(R) via the CCD bus.Some circuits are tested continuously; others are checked only under certain circumstances. The warning lamp is driven with messages relayed to the Mechanical Instrument Cluster (MIC) from the ACM via the CCD bus. The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be observed by the customer. Whenever the ignition key is turned to the "run" or "start" position,the airbag control module performs a lamp check by turning the AIRBAG warning lamp on for 6 - 8 seconds. If the lamp remains off, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains on, there could be an active fault in the system or the circuit that operates the lamp may be shorted to ground. If the lamp comes on and stays on for a period longer than 6-8 seconds, then goes off, there is usually an intermittent problem in the system. Perform the WARNING LAMP CIRCUIT OPEN procedure (refer to Testing and Inspection in this section) to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2333 Central Timer Module ( CTM ) High Option: Description and Operation Interior Lighting INTERIOR LIGHTING The courtesy lights are controlled by the CTM.

This system is available in a Base or Highline configuration. The Base CTM does not communicate on the CCD bus and will not be addressed. For concerns about the Base CTM, please refer to the appropriate Service Manual. The CTM performs most of the typical functions a Body Control Module would perform. The Highline CTM provides the following features: Remote Keyless Entry (RKE) - Chime - Courtesy Lamp Controls/Illuminated Entry - Power Door Locks - Speed Sensitive Intermittent Wipers - Enhanced Accident Response - Vehicle Theft Security System (VTSS) The module is located on the right side of the glove box behind a metal bracket. It contains a white 18-way and a green 14-way connector. CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODES Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure DESCRIPTION Two versions of the Central Timer Module (CTM) are available on this vehicle, a base version and a high-line version. The base version of the CTM is used on base models of the vehicle. The base version of the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, and an ignition lamp time delay relay in a single unit. The high-line version of the CTM is used on highline vehicles. The high-line CTM provides all of the functions of the base version CTM, but also is used to control and integrate many of the additional electronic functions and features included on the high-line models. The high-line version of the CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, reduce internal controller hardware, and reduce component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many new feature capabilities. One of the functions and features that both versions of the CTM support is the chime warning system. The CTM contains a chime tone generator to perform the functions of the chime warning module. The CTM uses hard-wired switch inputs, internal programming, and a hard-wired chime request input from the instrument cluster circuitry to detect when a chime tone is required. Both versions of the CTM are mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening. For diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The high-line Central Timer Module (CTM) can also control some features of the audio system when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The RAZ radio receiver with a remote radio switch option is one of the features that the CTM controls. The CTM is programmed to send switch status messages over the Chrysler Collision Detection (CCD) data bus to control the volume, seek, and pre-set station advance functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch status messages to the radio receiver. The electronic circuitry within the radio receiver responds to the switch status messages it receives by adjusting the radio settings as requested. Refer to Remote Radio Switch in the Description and Operation for more information on this component. In addition, radio receivers connected to the CCD data bus have several audio system functions that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more information on DRB testing of the audio systems. The high-line Central Timer Module (CTM) can also operate the horn system. A high-line CTM is used on high-line versions of this vehicle.

The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The horn relay is one of the hard wired outputs of the CTM. The high-line CTM is programmed to energize or deenergize the horn relay in response to certain inputs from the Remote Keyless Entry (RKE) system and/or the Vehicle Theft Security System (VTSS). Refer to Remote Keyless Entry System Description. Refer to Vehicle Theft Security System Description for more information on the VTSS. Both the base and the high-line versions of the CTM support the intermittent wipe and wipe-after-wash features, but only the high-line CTM supports the speed sensitive intermittent wipe. The intermittent wipe relay is one of the outputs that both the base and the high-line versions of the CTM can control. Each CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the high-line CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The high-line CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The high-line CTM receives hard-wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch while the driver door is open if the key is in the ignition and/or the headlamps are on. However, the locks can still be operated manually, with a key, or energized with the RKE transmitter. - A Panic Mode feature which can provide additional personal security and protection. When the Panic button on the RKE transmitter is depressed the vehicle horn will pulse, the headlights will flash, and the interior lights will illuminate on the vehicle for about three minutes, or until the Panic button is depressed a second time. A vehicle speed of about 24 kilometers-per-hour (15 miles-per-hour) will also cancel the panic mode. - An enhanced accident response feature will unlock both doors, then prevent the power door locks from locking the doors for a predetermined time interval, after receiving a CCD message from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course, these responses are dependent upon functional battery power and wiring circuitry following the impact. - Rolling door locks is a programmable feature of the power lock system. This feature will automatically lock all of the doors after the vehicle reaches a speed of about 24 kilometers-per-hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour). - A programmable feature of the RKE system is the enabling or disabling of the horn chirp following activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the horn chirp duration (twenty or forty milliseconds) can be selected. One of the features that the high-line CTM supports and controls is the Vehicle Theft Security System (VTSS). In the VTSS, the CTM receives hard- wired inputs from the door jamb, door lock cylinder, and ignition switches. The programming in the CTM allows it to process the information from these inputs and send control outputs to energize or de-energize the headlamp relay, horn relay, and the security lamp. The CTM also sends CCD data bus messages to the Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS. The high-line CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry (RKE) systems, which are integrated into the arming, disarming, and triggering functions of the VTSS. The programmable features of the CTM can be enabled or disabled using the DRB scan tool as described in the proper Diagnostic Procedures. Refer to Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the highline version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. This information covers the diagnosis and service of only the hard-wired inputs used by the CTM to determine that a chime tone should be generated. See Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced.

The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 +12 chimes per minute for reminders and High; 180 + 12 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: Ignition off, key in ignition, driver's door open - Ignition off, headlamps on, driver's door open - Seat belt warning - Check engine lamp illuminated (after prove-out) - Airbag lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out if equipped) - Check gauges lamp illuminated - Low fuel warning lamp illuminated - Low washer fluid Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2338 Central Timer Module ( CTM ) High Option: Description and Operation Airbag System AIRBAG SYSTEM The airbag system is designed to provide increased driver and passenger protection if the vehicle is involved in a front end collision. The system is most effective when used in conjunction with the seat belt system. The airbag control module (ACM) is an electronic module that monitors the airbag system for proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and contains the sensor and actuator that is responsible for airbag deployment. There are no external impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck at the bottom of the instrument panel. It is located forward of the console. The ACM provides diagnostic information (DTCs) to the technician through the DRB III(R) via the CCD bus.Some circuits are tested continuously; others are checked only under certain circumstances. The warning lamp is driven with messages relayed to the Mechanical Instrument Cluster (MIC) from the ACM via the CCD bus. The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be observed by the customer. Whenever the ignition key is turned to the "run" or "start" position,the airbag control module performs a lamp check by turning the AIRBAG warning lamp on for 6 - 8 seconds. If the lamp remains off, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains on, there could be an active fault in the system or the circuit that operates the lamp may be shorted to ground. If the lamp comes on and stays on for a period longer than 6-8 seconds, then goes off, there is usually an intermittent problem in the system. Perform the WARNING LAMP CIRCUIT OPEN procedure (refer to Testing and Inspection in this section) to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. Interior Lighting INTERIOR LIGHTING The courtesy lights are controlled by the CTM. The door switches are inputs to the CTM and the courtesy lights are outputs. The glove box lamp and the ash receiver lamp (if equipped) are not controlled by the CTM. They are hardwired to individual switches and fuses. The highline CTM also provides for illuminated entry option. If the CTM detects an unlock signal from the RKE transmitter, a door disarm switch input or the door jamb switch input, the interior courtesy lights will be turned on. The illuminated entry function is canceled if the CTM senses an ignition "on" condition or the "lock" command from a valid key fob If a door is left open or turned on by rotation of dimmer switch for more than fifteen minutes, the CTM will extinguish the lamps to avoid discharging the battery. If the lamps are turned on by courtesy lamp switch, the CTM will not be able to turn them off. Central Timer Module CENTRAL TIMER MODULE The Dakota (AN) utilizes a Central Timer Module (CTM). This system is available in a Base or Highline configuration. The Base CTM does not communicate on the CCD bus and will not be addressed. For concerns about the Base CTM, please refer to the appropriate Service Manual. The CTM performs most of the typical functions a Body Control Module would perform. The Highline CTM provides the following features: Remote Keyless Entry (RKE) - Chime - Courtesy Lamp Controls/Illuminated Entry - Power Door Locks - Speed Sensitive Intermittent Wipers - Enhanced Accident Response - Vehicle Theft Security System (VTSS) The module is located on the right side of the glove box behind a metal bracket. It contains a white 18-way and a green 14-way connector.

The base version of the CTM is used on base models of the vehicle. The base version of the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, and an ignition lamp time delay relay in a single unit. The high-line version of the CTM is used on highline vehicles. The high-line CTM provides all of the functions of the base version CTM, but also is used to control and integrate many of the additional electronic functions and features included on the high-line models. The high-line version of the CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, reduce internal controller hardware, and reduce component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many new feature capabilities. One of the functions and features that both versions of the CTM support is the chime warning system. The CTM contains a chime tone generator to perform the functions of the chime warning module. The CTM uses hard-wired switch inputs, internal programming, and a hard-wired chime request input from the instrument cluster circuitry to detect when a chime tone is required. Both versions of the CTM are mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening. For diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The high-line Central Timer Module (CTM) can also control some features of the audio system when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The RAZ radio receiver with a remote radio switch option is one of the features that the CTM controls. The CTM is programmed to send switch status messages over the Chrysler Collision Detection (CCD) data bus to control the volume, seek, and pre-set station advance functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch status messages to the radio receiver. The electronic circuitry within the radio receiver responds to the switch status messages it receives by adjusting the radio settings as requested. Refer to Remote Radio Switch in the Description and Operation for more information on this component. In addition, radio receivers connected to the CCD data bus have several audio system functions that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more information on DRB testing of the audio systems. The high-line Central Timer Module (CTM) can also operate the horn system. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The horn relay is one of the hard wired outputs of the CTM. The high-line CTM is programmed to energize or deenergize the horn relay in response to certain inputs from the Remote Keyless Entry (RKE) system and/or the Vehicle Theft Security System (VTSS). Refer to Remote Keyless Entry System Description. Refer to Vehicle Theft Security System Description for more information on the VTSS. Both the base and the high-line versions of the CTM support the intermittent wipe and wipe-after-wash features, but only the high-line CTM supports the speed sensitive intermittent wipe. The intermittent wipe relay is one of the outputs that both the base and the high-line versions of the CTM can control. Each CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the high-line CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The high-line CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The high-line CTM receives hard-wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2340 programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch while the driver door is open if the key is in the ignition and/or the headlamps are on. However, the locks can still be operated manually, with a key, or energized with the RKE transmitter. - A Panic Mode feature which can provide additional personal security and protection. When the Panic button on the RKE transmitter is depressed the vehicle horn will pulse, the headlights will flash, and the interior lights will illuminate on the vehicle for about three minutes, or until the Panic button is depressed a second time. A vehicle speed of about 24 kilometers-per-hour (15 miles-per-hour) will also cancel the panic mode. - An enhanced accident response feature will unlock both doors, then prevent the power door locks from locking the doors for a predetermined time interval, after receiving a CCD message from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course, these responses are dependent upon functional battery power and wiring circuitry following the impact. - Rolling door locks is a programmable feature of the power lock system. This feature will automatically lock all of the doors after the vehicle reaches a speed of about 24 kilometers-per-hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour). - A programmable feature of the RKE system is the enabling or disabling of the horn chirp following activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the horn chirp duration (twenty or forty milliseconds) can be selected. One of the features that the high-line CTM supports and controls is the Vehicle Theft Security System (VTSS). In the VTSS, the CTM receives hard- wired inputs from the door jamb, door lock cylinder, and ignition switches. The programming in the CTM allows it to process the information from these inputs and send control outputs to energize or de-energize the headlamp relay, horn relay, and the security lamp. The CTM also sends CCD data bus messages to the Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS. The high-line CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry (RKE) systems, which are integrated into the arming, disarming, and triggering functions of the VTSS. The programmable features of the CTM can be enabled or disabled using the DRB scan tool as described in the proper Diagnostic Procedures. Refer to Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the highline version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. This information covers the diagnosis and service of only the hard-wired inputs used by the CTM to determine that a chime tone should be generated.

Chime System CHIME SYSTEM The chime system is built into the CTM. The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 +12 chimes per minute for reminders and High; 180 + 12 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: Ignition off, key in ignition, driver's door open - Ignition off, headlamps on, driver's door open - Seat belt warning - Check engine lamp illuminated (after prove-out) - Airbag lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out if equipped) - Check gauges lamp illuminated - Low fuel warning lamp illuminated - Low washer fluid Compass Mini-Trip Computer (CMTC) COMPASS MINI-TRIP COMPUTER (CMTC) This system, located in the overhead console, displays information on outside temperature, compass direction and trip information. Compass And Temperature Display This display provides the outside temperature and one of eight compass readings to indicate the direction the vehicle is facing. Trip Odometer (ODO) Shows the distance traveled since the last reset. Average Fuel Economy (AVE ECO) Shows the average fuel economy in MPG (miles per gallon) or L/100Km since the last reset. Instantaneous Fuel Economy Shows the fuel economy for the last few seconds in MPG or L/100Km. Distance to Empty (DTE) Shows the estimated distance that can be traveled with the fuel remaining in the tank. This is calibrated using the MPG for the last few minutes. Elapsed Time (ET) Shows the accumulated ignition on time since the last reset. Step Button Press this button to cycle through all the mini-trip computer displays. US/M Button Press this button to convert all vehicle displays from US to Metric to US. To Reset the Display Press the Step and US/M buttons simultaneously for at least two seconds and all resettable conditions will be reset. This will occur only if a resettable function (AVG ECO,Trip Odometer, ET) is currently being displayed. Automatic Compass Calibration This compass is self calibrating which eliminates the need to manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL symbol will be displayed. After completing three 360' turns in an area free from large metal or metallic objects, the CAL symbol will turn off and the compass will function normally. Compass Variance Compass Variance is the difference between Magnetic North and Geographic North. In some areas of the country, the difference between Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2342 Magnetic and Geographic North is great enough to cause the compass to give false readings. If this occurs, the compass vanance must be set. To set the variance: Turn the ignition ON and set display to Comp./Temp. While pressing the US/M button, press the STEP button for approximately five seconds. The "VAR" symbol will light and the last variance zone number will be displayed. Press the US/Metric Button to select the proper variance zone as shown on the map. Press the Step button to set the new variance zone and resume normal operation. Diagnostics DIAGNOSTICS The CTM is fully addressable with the DRB III(R) and it is the recommended method for diagnosis. The CTM reports 6 Diagnostic Trouble Codes. All of the inputs to the CTM can be read with the DRB and the outputs can be actuated. DRB III Error Messages and Blank Screen DRB III(R) ERROR MESSAGES AND BLANK SCREEN Under normal operation, the DRB will display one of only two error messages: User-Requested WARM Boot or User-Requested COLD Boot If the DRB should display any other error message, record the entire display an call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display: ver: 2.14 date: 26 Jul93 file: key itf.cc date: Jul 26 1993 line: 548 err: 0x1 User-Requested COLD Boot Press MORE to switch between this display and the application screen. Press F4 when done noting information. DRB III(R) does not power up (Blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRB may be the result of faulty cable or vehicle wiring. Perform the "Blank Screen" test under Testing and Inspection, Non-Diagnostic Trouble Codes in this section. Display is not visible Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition. Enhanced Accident Response (Highline CTM Only) ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned on when the vehicle speed message on the CCD bus indicates 0 mph or the message is not present. In addition to unlocking the doors, the door lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "off" position, normal operation will resume. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2343 Glossary of Terms/Acronyms GLOSSARY OF ACRONYMS ACM airbag control module CCD Chrysler Collision Detection (vehicle communication bus) DAB driver airbag DLC data link connector EM entry module PAB passenger airbag PCM powertrain control module PDC power distribution center SQUIB also called indicator (located in rear of airbag module) Mechanical Instrument Cluster (MIC) MECHANICAL INSTRUMENT CLUSTER (MIC) The MIC is available in 4 different versions. Two of the versions are Canadian clusters. There is a highline and a low line cluster available. The difference is the addition of a tachometer in the highline. In order to accomplish this, the fuel level gauge is reduced in size and oil pressure gauge is relocated. The cluster positions it's gauges with bus messages received from the PCM. The odometer is a Liquid Crystal Display (LCD). The cluster will provide bus bias and the PCM provides termination. The MIC has an internal diagnostic routing that can be accessed by pushing and holding the trip odometer while rotating the key to the on position. The cluster will then place all the gauges at their calibration points and will light all the CCD driven tell-tales. It will also light all the segments of the LCD display for a visual verification check. The MIC can verify communications with the PCM, ID the module, or change the country code by using options 1, 3, or 9 on the DRB III(R) under the MIC menu. If there are faults found during the diagnostic routine, the cluster will report them on the LCD odometer display. For further information about the diagnostic routine and the explanation of the faults, please refer to Instrument Panel, Testing and Inspection. Power Door Lock System POWER DOOR LOCKS The CTM controls the door lock actuator assemblies to handle locking and unlocking with the key fob or interior switch. There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is off, the door is open, and the key is in the ignition. Automatic or "rolling locks" are included as a DRB III(R) or customer programmable feature. If the vehicle is moving approximately 15 mph and approximately 10 degrees of throttle opening is seen by the PCM, (the PCM will send this info to the CTM via the CCD bus) indicating acceleration, the CTM will cycle the lock actuators to lock the doors. Remote Keyless Entry (RKE) /Vehicle Theft Security System (VTSS) RKE/VTSS If the vehicle is equipped with Remote Keyless Entry (RKE), programming of additional transmitters and horn chirp are customer programmable features. The highline CTM provides for RKE and the Vehicle Theft Security System (VTSS). The base CTM is not able to provide these functions. The presence of either of these options dictates that the vehicle is equipped with a highline CTM. The VTSS system monitors the door ajar switches and ignition switch to detect unauthorized entry into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to start the engine, it will start and stall, If the trigger condition is still present, the lights will continue to flash for an additional 15 minutes After 15 minutes the system will stop pulsing the lights and return to the "armed" state.The cause of the last 4 alarm triggers is stored by the CTM and may be retrieved by the DRB III(R).The system may be disarmed by either an unlock command from a valid RKE key fob or by using a key in either door. Both front door key cylinders are equipped with disarm switches. There is also a VTSS lamp on the dash that provides information to the driver about the state of the vehicle theft system. The RKE system is placed in the programming mode by the DRB III(R), or by using the customer programming sequence. The system will store up to four key fob codes. Two fobs are supplied with the truck, additional fobs may be purchased through parts department. The additional fobs can be programmed with the DRB III(R), or by using the customer programming sequence. Through the DRB III(R), erasing and programming of one key fob without deleting the others is possible. If the key fob is stolen, all the fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense of security.

There are two additional modules, the Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are performed through the Serial Communication Interface of SCI, the same as previous years. All of the information about the functioning of all the systems is organized controlled, and communicated by the CCD bus, which is described in (CCD Bus) of this general information. Through the CCD bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require all the information to perform it's function. It will only respond to messages "addressed" to it through a binary coding process. This method of data transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. Airbag Trouble Code Types and Descriptions AIRBAG DIAGNOSTIC TROUBLE CODES Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists,diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this book to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRB, The procedure begins with AIRBAG TEST 1A-Identifying Airbag System Problems. This will direct you to the specific test(s) that must be performed. Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures, diagnostic trouble codes are used as a diagnostic tool. Active Codes The code becomes active as soon as the malfunction is detected and stored after one minutes of occurrence or key-off, whichever occurs first. An active trouble code indicates an on-going malfunction. This means that the defect is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present. Stored Codes Airbag codes are automatically stored in the ACM's memory after one minute of occurrence or when the ignition is turned off. The exception is the "Loss of Ignition Run Only" code which is an active code only. A "stored" code indicates there was an active code present at some time. However, the code currently may not be present as an active code, although another active code could be. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2345 If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem. In this case, the stored code can indicate an area to inspect. If no obvious problems are found, erase stored codes, and with the "on" wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is difficult to locate. Airbag Diagnostic Trouble Codes The airbag control module may report any of the following diagnostic trouble codes. For the following codes, replace the Airbag Control Module (ACM) even if set intermittently: ACM Accelerometer - Internal Diagnostic 1 - Internal Diagnostic 2 For the following codes, replace the airbag control module (ACM): ACM Output Driver - ACM Stored Energy Logic - ACM Stored Energy Driver - ACM Stored Energy Passenger - Internal Diagnostic 3 - Internal Diagnostic 4 - Safing Sensor Shorted - Warning Lamp Driver Error For these codes, refer to the appropriate diagnostic procedure: Driver Squib Open Driver Squib Shorted Loss of Ignition Run Only Loss of Ignition Run/Start No CCD Communication Passenger Squib Circuit Open Passenger Squib Circuit Shorted Either Squib Terminal Short to Battery Either Squib Terminal Short to Ground Warning Lamp Circuit Open Warning Lamp Circuit Shorted Central Timer Module Diagnostic Trouble Codes CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODES Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure Vehicle Communication VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the highest priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a "voltage divider network" located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems may use more than one. Some modules are capable of both biasing and terminating. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. In this vehicle, the bias is supplied by the instrument cluster and termination is provided by the PCM and the instrument cluster. Without termination,voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLE'S ON-BOARD Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 2346 DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING. IF THERE IS A PROBLEM, REFER TO TESTING AND INSPECTION IN THIS SECTION. BUS FAILURE MESSAGES Short to Battery - Either or both of the bus wires are shorted to the battery potential. Or open ground to any CCD bus module. Short to 5 Volts - Either or both of the bus wires are shorted to a 5 volt potential. Short to Ground - Either or both of the bus wires are shorted to ground. Bus (+) & (-) Shorted Together - The two bus wires are shorted together. No Termination - The bus system has lost connection with all of its terminators. Bus Bias Level Too Low - Either or both of the bus wire potentials are significantly below their normal 2.5 volts. Bus Bias Level Too High - Either or both of the bus wire potentials are significantly above their normal 2.5 volts. No Bus Bias - The bus system has lost connection with Instrument Cluster. Bus (+) Open - The bus (+) wire has lost connection with termination and/or bias. Bus (-) Open - The bus (-) wire has lost connection with termination and/or bias. Not Receiving Bus Messages Correctly - The DRB cannot communicate over the bus and does not know why. Warnings WARNINGS Vehicle Damage Warnings Before disconnecting any control module, make sure the ignition is "off". Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side(not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. Road testing a complaint vehicle Some of the complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition. CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE REASSEMBLED. DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION. DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR OPERATE IT YOURSELF. HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB. Wiper System SPEED SENSITIVE INTERMITTENT WIPERS The AN truck equipped with a highline CTM will utilize speed sensitive intermittent wipers. Only a highline CTM will be able to support this feature. A base CTM will provide for intermittent wipers without the speed sensitive feature. The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, an immediate wipe of the windshield takes place and the new delay interval is implemented. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Testing and Inspection > Reading and Clearing Diagnostic Trouble Codes Central Timer Module ( CTM ) High Option: Reading and Clearing Diagnostic Trouble Codes With Scan Tool Data Link (Diagnostic) Connector Location Technicians must retrieve stored DTC's by connecting the DRB scan tool (or an equivalent scan tool) to the 16-way data link connector.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2408 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2409 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2410 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2411 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2412 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2413 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number for the subsequent diagram will match a listed group shown. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2414 Connector and Terminal Replacement 1.

Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2423 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2424 3.

Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2425 Powertrain Control Module: Connector Views Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2426 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Page 2427 Powertrain Control Module: Description and Operation Powertrain Control Module (PCM) The Powertrain Control Module (PCM) is located in the engine compartment. The ignition system is controlled by the PCM. NOTE: Base ignition timing by rotation of distributor is not adjustable on any of these engines. The PCM opens and closes the ignition coil ground circuit to operate the ignition coil. This is done to adjust ignition timing, both initial (base) and advance, and for changing engine operating conditions. The amount of electronic spark advance provided by the PCM is determined by five input factors: engine coolant temperature, engine rpm, intake manifold temperature, manifold absolute pressure and throttle position. Speed Control Operation The speed control electronic control circuitry is integrated into the PCM. The PCM speed control functions are monitored by the On-Board Diagnostics (OBD). All OBD-sensed systems are monitored by the PCM. Each monitored circuit is assigned a Diagnostic Trouble Code (DTC). The PCM will store a DTC in electronic memory for certain failures it detects. See On-Board Diagnostic Test For Speed Control System for more information. The PCM cannot be repaired and must be replaced if faulty. PCM Control of Automatic Transmission The PCM controls operation of the converter clutch, overdrive clutch, and governor pressure solenoid. The control module determines transmission shift points based on input signals from the transmission thermistor, transmission output shaft speed sensor, crankshaft position sensor, vehicle speed sensor, throttle position sensor, and battery temperature sensor. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information > Diagrams > Page 2428 Powertrain Control Module: Service and Repair PCM Location And Mounting The PCM is located in the engine compartment.

The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Camshaft Position Sensor-Typical (Distributor Shown) CAMSHAFT POSITION SENSOR-PCM INPUT A sync signal is provide by the camshaft position sensor. The sensor located in the distributor on all engines. The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs. This is done to establish and maintain correct injector firing order. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Locations > Page 2452 Camshaft Position Sensor: Testing and Inspection Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines. To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain Diagnostics Procedures service manual. To test the sensor only, refer to the following: For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips. 1. Connect the positive (+) voltmeter lead into the sensor output wire. This is at done the distributor wire harness connector. 2. Connect the negative (-) voltmeter lead into the ground wire. 3. Set the voltmeter to the 15 Volt DC scale. 4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup. 5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 6. If voltage is not present, check the voltmeter leads for a good connection. 7. If voltage is still not present, check for voltage at the supply wire. 8. If 5 volts is not present at supply wire, check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for this test. 9. If voltage is still not present, perform vehicle test using the DRB scan tool. 10. If voltage is present at cavity A-17, but not at the supply wire: a. Check continuity between the supply wire. This is checked between the distributor connector and cavity A-17 at the PCM. If continuity is not present, repair the harness as necessary. b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the PCM. If continuity is not present, repair the harness as necessary. c. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary. 11. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. If sync pulse signal is not present, replacement of the camshaft position sensor is necessary. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Camshaft Position Sensor > Component Information > Locations > Page 2453 Camshaft Position Sensor: Service and Repair Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines.

The sensor provides an input voltage to the powertrain control module (PCM) relating coolant temperature. The PCM uses this input along with inputs from other sensors to determine injector pulse width and ignition timing. As coolant temperature varies, the coolant temperature sensor resistance will change. This change in resistance results in a different input voltage to the PCM. When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air-fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Coolant Temperature Sensor/Switch (For Computer) > Component Information > Specifications > Page 2461 Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection To perform a complete test of the engine coolant temperature sensor and its circuitry, refer to DRB scan tool and appropriate Powertrain Diagnostics Procedures.

The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing. The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it. Sensor Operation The flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its outer edge. The notches cause a pulse to be generated when they pass under the sensor. The pulses are the input to the PCM. For each engine revolution, there are 8 pulses generated. The engine will not operate if the PCM does not receive a crankshaft position sensor input. CRANKSHAFT POSITION SENSOR-PCM INPUT This sensor is a hall effect device that detects notches in the flywheel (manual transmission) or flexplate (automatic transmission). This sensor is used to indicate to the powertrain control module (PCM) that a spark and or fuel injection event is to be required. The output from this sensor, in conjunction with the camshaft position sensor signal, is used to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders.

They are: Left, right, pre-catalyst and post catalyst. The left, right and post catalyst sensors will fine-tune air-fuel ratio. The pre-catalyst and post catalyst sensors will determine catalytic converter efficiency. Two of these sensors are installed into the left and right exhaust manifold downpipes. The left O2S sensor will monitor cylinders 1, 3, 5 and 7. The right sensor will monitor cylinders 2, 4, 6 and 8. The sensors produce voltages from 0 to 1 volt, depending upon the oxygen content of the exhaust gas in the exhaust manifold. When a large amount of oxygen is present (caused by a lean air/fuel mixture), the sensors produces a low voltage. When there is a lesser amount present (rich air/fuel mixture) it produces a higher voltage. By monitoring the oxygen content and converting it to electrical voltage, the sensors act as a rich-lean switch. The oxygen sensors are equipped with a heating element that keeps the sensors at proper operating temperature during all operating modes. Maintaining correct sensor temperature at all times allows the system to enter into closed loop operation sooner. Also, it allows the system to remain in closed loop operation during periods of extended idle. In Closed Loop operation, the PCM monitors the O2S sensor input (along with other inputs) and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values and inputs from other sensors. The Automatic Shutdown (ASD) relay supplies battery voltage to both oxygen sensors. The oxygen sensors are equipped with a heating elements. The heating elements reduce the time required for the sensors to reach operating temperature. PRE-CATALYST OXYGEN SENSOR The pre-catalyst O2S sensor is located in the inlet end of the catalytic converter. It provides an input voltage to the PCM. By comparing the input from the pre-catalyst O2S sensor, with the input from the post catalyst oxygen sensor, the PCM calculates catalytic convertor efficiency. POST CATALYST OXYGEN SENSOR The post catalyst heated oxygen sensor threads into the outlet end of the catalytic convertor. The post catalyst heated oxygen sensor input is used to detect catalytic convertor deterioration and fine tune the air fuel ratio. As the convertor deteriorates, the input from this sensor begins to match the pre-catalyst sensor input except for a slight time delay. By comparing the inputs from both of these sensors, the PCM calculates catalytic convertor efficiency. When the catalytic converter efficiency drops below emission standards, the PCM stores a diagnostic trouble code and illuminates the Malfunction Indicator Lamp (MIL). For more information, refer to Emission Control Systems. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Oxygen Sensor > Component Information > Diagrams > Page 2509 Oxygen Sensor: Testing and Inspection To perform a complete test of the O2S sensors and their circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures.

Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2536 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2537 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2538 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2549 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2550 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2551 Connector Pin Identification Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Page 2552 Vehicle Speed Sensor: Description and Operation VEHICLE SPEED AND DISTANCE-PCM INPUT Vehicle speed and distance covered are measured by the Rear Wheel Speed Sensor. The sensor is mounted to the rear axle. A signal is sent from this sensor to the Controller Antilock Brake (CAB) computer. A signal is then sent from the CAB to the Powertrain Control Module (PCM) to determine vehicle speed and distance covered. The PCM will then determine strategies for fuel system and speed control system operation. For additional information on the Rear Wheel Speed Sensor, refer to Brakes and Traction Control / Sensors and Switches - Brakes and Traction Control / Wheel Speed Sensor.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Specifications > Page 2559 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the TPS only, refer to the following: TPS The TPS can be tested with a digital voltmeter. The center electrical terminal of the TPS is the output terminal. With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT). At idle, TPS output voltage should be greater than 0.26 volts but less than 0.95 volts. At wide open throttle, TPS output voltage must be less than 4.49 volts. The output voltage should increase gradually as the throttle plate is slowly opened from idle to WOT. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Throttle Position Sensor > Component Information > Specifications > Page 2560 Throttle Position Sensor: Service and Repair REMOVAL The TPS is located on side of throttle body. 1.

IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2574 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2575 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2576 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2587 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2588 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Diagram Information and Instructions > Page 2589 Connector Pin Identification Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Vehicle Speed Sensor > Component Information > Diagrams > Page 2590 Vehicle Speed Sensor: Description and Operation VEHICLE SPEED AND DISTANCE-PCM INPUT Vehicle speed and distance covered are measured by the Rear Wheel Speed Sensor. The sensor is mounted to the rear axle. A signal is sent from this sensor to the Controller Antilock Brake (CAB) computer. A signal is then sent from the CAB to the Powertrain Control Module (PCM) to determine vehicle speed and distance covered. The PCM will then determine strategies for fuel system and speed control system operation. For additional information on the Rear Wheel Speed Sensor, refer to Brakes and Traction Control / Sensors and Switches - Brakes and Traction Control / Wheel Speed Sensor. See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Wheel Speed Sensor Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Voltage Signal > Component Information > Description and Operation Voltage Signal: Description and Operation BATTERY VOLTAGE-PCM INPUT The battery voltage input provides power to the Powertrain Control Module (PCM). It also informs the PCM what voltage level is supplied to the ignition coil and fuel injectors. If battery voltage is low, the PCM will increase injector pulse width period of time that the injector is energized). This is done to compensate for the reduced flow through injector caused by the lowered voltage. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Description and Operation Catalytic Converter: Description and Operation The stainless steel catalytic converter body is designed to last the life of the vehicle. Excessive heat can result in bulging or other distortion, but excessive heat will not be the fault of the converter. If unburned fuel enters the converter, overheating may occur. If a converter is heat-damaged, correct the cause of the damage at the same time the converter is replaced. Also, inspect all other components of the exhaust system for heat damage. Unleaded gasoline must be used to avoid contaminating the catalyst core. DO NOT remove spark plug wires from plugs or by any other means short out cylinders. Failure of the catalytic converter can occur due to a temperature increase caused by unburned fuel passing through the converter. DO NOT allow the engine to operate at fast idle for extended periods (over 5 minutes). This condition may result in excessive temperatures in the exhaust system and on the floor pan. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Catalytic Converter > Component Information > Description and Operation > Page 2598 Catalytic Converter: Service and Repair CAUTION: When servicing or replacing exhaust system components, disconnect the oxygen sensor connector(s). Allowing the exhaust to hang by the oxygen sensor wires will damage the harness and/or sensor. REMOVAL 1. Raise and support the vehicle. 2. Saturate the bolts and nuts with heat valve lubricant.

The solenoid regulates the rate of vapor flow from the EVAP canister to the intake manifold. The PCM operates the solenoid. During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation. The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition. Duty Cycle EVAP Purge Solenoid The solenoid attaches to a bracket located at the left-rear side of the engine compartment. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Canister Purge Solenoid > Component Information > Locations > Page 2605 Canister Purge Solenoid: Service and Repair Duty Cycle EVAP Canister Purge Solenoid The duty cycle EVAP canister purge solenoid is located at left-rear side of engine compartment near power brake vacuum unit.

A thorough inspection for pinched, kinked, or disconnected supply vacuum lines (as currently listed in the Powertrain Diagnostic Procedures) is a critical step in diagnosing DTC P1494 (LDP SW OR MECHANICAL FAULT). Additionally, the other evaporative leak faults (DTC P0442 SMALL LEAK, P0455 - LARGE LEAK, and P0456 - VERY SMALL LEAK) should have the supply vacuum lines examined for pinches or kinks prior to any LDP component replacement.

Leaks in the system, even small ones, can allow fuel vapors to escape into the atmosphere. Government regulations require on-board testing to make sure that the evaporative (EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and blockage. It also performs self-diagnostics. During self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2620 EVAP LEAK DETECTION SYSTEM COMPONENTS Service Port: Used with special tools like the Miller Evaporative Emissions Leak Detector (EELD) to test for leaks in the system. EVAP Purge Solenoid: The PCM uses the EVAP purge solenoid to control purging of excess fuel vapors stored in the EVAP canister. It remains closed during leak testing to prevent loss of pressure. EVAP Canister The EVAP canister stores fuel vapors from the fuel tank for purging. EVAP Purge Orifice: Limits purge volume. EVAP System Air Filter: Provides air to the LDP for pressurizing the system. It filters out dirt while allowing a vent to atmosphere for the EVAP system. Leak Detection Pump (LDP) Components The main purpose of the LDP is to pressurize the fuel system for leak checking. It closes the EVAP system vent to atmospheric pressure so the system can be pressurized for leak testing. The diaphragm is powered by engine vacuum. It pumps air into the EVAP system to develop a pressure of about 7.5' H20(1/4) psi. A reed switch in the LDP allows the PCM to monitor the position of the LDP diaphragm. The PCM uses the reed switch input to monitor how fast the LDP is pumping air into the EVAP system. This allows detection of leaks and blockage. The LDP assembly consists of several parts. The solenoid is controlled by the PCM, and it connects the upper pump cavity to either engine vacuum or atmospheric pressure. A vent valve closes the EVAP system to atmosphere, sealing the system during leak testing. The pump section of the LDP consists of a diaphragm that moves up and down to bring air in through the air filter and inlet check valve, and pump it out through an outlet check valve into the EVAP system. The diaphragm is pulled up by engine vacuum, and pushed down by spring pressure, as the LDP solenoid turns on and off. The LDP also has a magnetic reed switch to signal diaphragm position to the PCM. When the diaphragm is down, the switch is closed, which sends a 12 V (system voltage) signal to the PCM. When the diaphragm is up, the switch is open, and there is no voltage sent to the PCM. This allows the PCM to monitor LDP pumping action as it turns the LDP solenoid on and off. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2621 LDP AT REST (NOT POWERED) When the LDP is at rest (no electrical/vacuum) the diaphragm is allowed to drop down if the internal (EVAP system) pressure is not greater than the return spring. The LDP solenoid blocks the engine vacuum port and opens the atmospheric pressure port connected through the EVAP system air filter. The vent valve is held open by the diaphragm. This allows the canister to see atmospheric pressure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2622 DIAPHRAGM UPWARD MOVEMENT When the PCM energizes the LDP solenoid, the solenoid blocks the atmospheric port leading through the EVAP air filter and at the same time opens the engine vacuum port to the pump cavity above the diaphragm. The diaphragm moves upward when vacuum above the diaphragm exceeds spring force. This upward movement closes the vent valve. It also causes low pressure below the diaphragm, unseating the inlet check valve and allowing air in from the EVAP air filter. When the diaphragm completes its upward movement, the LDP reed switch turns from closed to open. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2623 DIAPHRAGM DOWNWARD MOVEMENT based on reed switch input, the PCM de-energizes the LDP solenoid, causing it to block the vacuum port, and open the atmospheric port. This connects the upper pump cavity to atmosphere through the EVAP air filter. The spring is now able to push the diaphragm down. The downward movement of the diaphragm closes the inlet check valve and opens the outlet check valve pumping air into the evaporative system. The LDP reed switch turns from open to closed, allowing the PGM to monitor LDP pumping (diaphragm up/down) activity. During the pumping mode, the diaphragm will not move down far enough to open the vent valve The pumping cycle is repeated as the solenoid is turned on and off. When the evaporative system begins to pressurize, the pressure on the bottom of the diaphragm will begin to oppose the spring pressure, slowing the pumping action. The PCM watches the time from when the solenoid is de-energized, until the diaphragm drops down far enough for the reed switch to change from opened to closed. If the reed switch changes too quickly, a leak may be indicated. The longer it takes the reed switch to change state, the tighter the evaporative system is sealed. If the system pressurizes too quickly, a restriction somewhere in the EVAP system may be indicated. PUMPING ACTION During portions of this test, the PCM uses the reed switch to monitor diaphragm movement. The solenoid is only turned on by the PCM after the reed switch changes from open to closed, indicating that the diaphragm has moved down. At other times during the test, the PCM will rapidly cycle the LDP solenoid on and off to quickly pressurize the system. During rapid cycling, the diaphragm will not move enough to change the reed switch state. In the state of rapid cycling, the PCM will use a fixed time interval to cycle the solenoid. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2624 Leak Detection Pump: Testing and Inspection ENABLING CONDITIONS TO RUN EVAP LEAK DETECTION TEST NOTE: The following values are approximate and vehicle specific. Use the values seen in pre test/monitor test screen on the DRB III. See TSB 25-02-98 for more detail 1. Cold start: with ambient temperature (obtained from modeling the inlet air temperature sensor on passenger vehicles and the battery temperature sensor on Jeep & truck vehicles) between 4C° (40° F) and 32° C (90° F) for 0.040 leak. Between 4C° (40° F) and 29° C (85° F) for 0.020 leak. 2. Engine coolant temperature within:-12° to -8°C (10° to 18°F) of battery/ambient. 3. Battery voltage between 10 and 15 volts. NOTE: If battery voltage drops below 10 volts for more than 5 seconds during engine cranking, the EVAP leak detection test will not run. 4. Low fuel warning light off (fuel level must be between 15% and 85% for 0.040 leak and 30% and 85% for 0.020 leak). 5. MAP sensor reading 22 in Hg or above (This is the manifold absolute pressure, not vacuum). 6. No engine stall during test. If the system does not pass the EVAP Leak Detection Test, the following DTCs may be set: - P0442 - EVAP LEAK MONITOR 0.040" LEAK DETECTED - P0455 - EVAP LEAK MONITOR LARGE LEAK DETECTED - P0456 - EVAP LEAK MONITOR 0.020" LEAK DETECTED - P1486 - EVAP LEAK MON PINCHED HOSE FOUND - P1494 - LEAK DETECTION PUMP SW OR MECH FAULT - P1495 - LEAK DETECTION PUMP SOLENOID CIRCUIT A DTC will not be set if a one-trip fault is set or if MIL is illuminated for any of the following: - Purge Solenoid Electrical Fault - All Engine Controller Self Test Faults - All Cam And/or Crank Sensor Fault - All Map Sensor Faults - Ambient/battery Temperature Sensor Electrical Faults - All Coolant Sensor Faults - All TPS Faults - LDP Pressure Switch Fault - EGR Solenoid Fault - All Injector Faults - Baro Our Of Range - Vehicle Speed Faults - LDP Solenoid Circuit Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2625 Figure 6 EVAP leak detection test sequence When the ignition key is turned to "ON" the LDP diaphragm should be in the down position and the LDP reed switch should be closed. If the EVAP system has residual pressure, the LDP diaphragm may be up. This could result in the LDP reed switch being open when the key is turned to "ON" and a P1494 fault could be set because the PCM is expecting the reed switch to be closed. After the key is turned "ON", the PCM immediately tests the LDP solenoid circuit for electrical faults. If a fault is detected, DTC P1495 will set, the MIL will illuminate, and the remaining EVAP Leak Detection Test is canceled. NOTE: If battery temperature is not within range, or if the engine coolant temperature is not within a specified range of the battery temperature, the PCM will not run tests for DTC P1494, P1486, P0442, P0455 and P0441. These temperature calibrations may be different between models. FIGURE 6 SECTION 2 If DTC P1495 is not set, the PCM will check for DTC P1494. If the LDP reed switch was closed when the key was turned to "ON", the PCM energizes the LDP solenoid for up to 8 seconds and monitors the LDP switch. As the LDP diaphragm is pulled up by engine vacuum, the LDP reed switch should change from closed to open. If it does not, the PCM sets a temporary fault (P1494) in memory, and waits until the next time the Enabling Conditions are met to run the test again. If this is again detected, P1494 is stored and the MIL is illuminated. If the problem is not detected during the next enabling cycle, the temporary fault will be cleared. However, if the PCM detects the reed switch open when the key is turned to "ON", the PCM must determine if this condition is due to residual pressure in the EVAP system, or an actual fault. The PCM stores information in memory on EVAP system purging from previous engine run or drive cycles. If little or no purging took place, residual pressure could be holding the LDP diaphragm up, causing the LDP switch to be open. Since this is not a malfunction, the PCM cancels the EVAP Leak Detection Test without setting the temporary fault. If there was sufficient purging during the previous cycle to eliminate EVAP system pressure, the PCM judges that this is a malfunction and sets a temporary fault in memory. The next time that the Enabling Conditions are met, the test will run again. If the fault is again detected, the MIL will Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2626 illuminate and DTC 1494 will be stored. If the fault is not detected, the temporary fault will be cleared. FIGURE 6 SECTION 3 If no fault has been detected so far, the PCM begins testing for possible blockage in the EVAP system between the LDP and the fuel tank. This is done by monitoring the time required for the LDP to pump air into the EVAP system during two to three pump cycles. If no blockage is present, the LDP diaphragm is able to quickly pump air out of the LDP each time the PCM turns oft the LDP solenoid. If a blockage is present, the PCM detects that the LDP takes longer to complete each pump cycle. If the pump cycles take longer than expected (approximately 6 to 10 seconds) the PCM will suspect a blockage. On the next drive when Enabling Conditions are met, the test will run again. If blockage is again detected, P1486 is stored, and the MIL is illuminated. FIGURE 6 SECTION 4 After the LDP blockage tests are completed, the PCM then tests for EVAP system leakage. First, the PCM commands the LDP to rapidly pump for 20 to 50 seconds (depending on fuel level) to build pressure in the EVAP system. This evaluates the system J18-24-0 to see if it can be sufficiently pressurized. This evaluation (rapid pump cycling) may occur several times prior to leak checking. The LDP reed switch does not close and open during rapid pumping because the diaphragm does not travel through its full range during this part of the test. FIGURE 6 SECTION 5 Next, the PCM performs one or more test cycles by monitoring the time required for the LDP reed switch to close (diaphragm to drop) after the LDP solenoid is turned off. If the switch does not close, or closes after a long delay, it means that the system does not have any significant leakage and the EVAP Leak Detection Test is complete. However, if the LDP reed switch closes quickly, there may be a leak or the fuel level may be low enough that the LDP must pump more to finish pressurizing the EVAP system. In this case, the PCM will rapidly pump the LDP again to build pressure in the EVAP system, and follow that by monitoring the time needed for several LDP test cycles. This process of rapid pumping followed by several LDP test cycles may repeat several times before the PCM judges that a leak is present. When leaks are present, the LDP test cycle time will be inversely proportional to the size of the leak. The larger the leak, the shorter the test cycle time. The smaller the leak, the longer the test cycle time. DTC's may be set when a leak as small as 0.5 mm (0.020") diameter is present. If the system detects a leak, a temporary fault will be stored in PCM memory. The time it takes to detect a .020, .040, or Large leak is based on calibrations that vary from model to model. The important point to remember is if a leak is again detected on the next EVAP Leak Detection Test, the MIL will illuminate and a DTC will be stored based on the size of leak detected. If no leak is detected during the next test, the temporary fault will be cleared. DIAGNOSTIC TIPS During diagnosis, you can compare the LDP solenoid activity with the monitor sequence in Figure 6. If the PCM detects a problem that could set a DTC, the testing is halted and LDP solenoid activity will stop. As each section of the test begins, it indicates that the previous section passed successfully. By watching to see which tests complete, you can see if any conditions are present that the PCM considers abnormal. For example, if the LDP solenoid is energized for the test cycles to test for blockage (P1486), it means that the LDP has already passed its test for P1494. Then, if the PCM detects a possible blockage, it will set a temporary fault without turning on the MIL and continue the leak portion of the test. However, the PCM will assume that the system is already pressurized and skip the rapid pump cycles. Always diagnose leaks, if possible, before disconnecting connections. Disconnecting connections may mask a leak condition. Keep in mind that if the purge solenoid seat is leaking, it could go undetected since the leak would end up in the intake manifold. Disconnect the purge solenoid at the manifold when leak checking. In addition, a pinched hose fault (P1486) could set if the purge solenoid does not purge the fuel system properly (blocked seat). The purge solenoid must vent the fuel system prior to the LDP system test. If the purge solenoid cannot properly vent the system the LDP cannot properly complete the test for P1486 and this fault can set due to pressure being in the EVAP system during the test sequence. Multiple actuation's of the DRB Ill® Leak Detection Pump (LDP) Monitor Test can hide a 0.020 leak because of excess vapor generation. Additionally, any source for additional vapor generation can hide a small leak in the EVAP system. Excess vapor generation can delay the fall of the LDP diaphragm thus hiding the small leak. An example of this condition could be bringing a cold vehicle into a warm shop for testing or high ambient temperatures. Fully plugged and partially plugged underhood vacuum lines have been known to set MIL conditions. P1494 and P0456 can be set for this reason. Always, thoroughly, check plumbing for pinches or blockage before condemning components. TEST EQUIPMENT The Evaporative Emission Leak Detector (EELD) Miller Special Tool 8404 is capable of visually detecting leaks in the evaporative system and will take Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2627 the place of the ultrasonic leak detector 6917A. The EELD utilizes shop air and a smoke generator to visually detect leaks down to 0.020 or smaller. The food grade oil used to make the smoke includes an UV trace dye that will leave telltale signs of the leak under a black light. This is helpful when components have to be removed to determine the exact leak location. For detailed test instructions, follow the operators manual packaged with the EELD. IMPORTANT Be sure that the PCM has the latest software update. Reprogram as indicated by any applicable Technical Service Bulletin. After LDP repairs are completed, verify the repair by running the DRB Ill® Leak Detection Pump (LDP) Monitor Test as described in Technical Service Bulletin 18-12-99. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak Detection Pump, Evaporative System > Component Information > Technical Service Bulletins > Page 2628 Leak Detection Pump: Service and Repair Leak Detection Pump (LDP) Location LDP Filter Location The LDP is located in the engine compartment under the battery tray and Power Distribution Center (PDC).

Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: - Fuel pressure bleeding past a fuel injector(s). - Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose.

Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pressure > System Information > Specifications > Page 2649 6. Observe test gauge. Normal operating pressure should be 339 kPa ± 34 kPa (49.2 psi ± 5 psi). 7. Shut engine off. 8. Pressure should not fall below 30 psi for five minutes. 9. If pressure falls below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine off. 12. Testing for fuel injector or fuel rail leakage: Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking. 13. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage: Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line. If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump or filter/regulator may be leaking. Note: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A slow loss of pressure usually indicates a defective check valve in the electric fuel pump. The electric fuel pump is not serviced separately. Replace the fuel pump module assembly. The filter/ regulator may be replaced separately on certain applications.

The injector contains a pintle that closes off an orifice at the nozzle end. When electric current is supplied to the injector, the armature and needle move a short distance against a spring, allowing fuel to flow out the orifice. Because the fuel is under high pressure, a fine spray is developed in the shape of a pencil stream. The spraying action atomizes the fuel, adding it to the air entering the combustion chamber. An individual fuel injector is used for each individual cylinder. The top (fuel entry) end of the injector is attached into an opening on the fuel rail. The nozzle (outlet) ends of the injectors are positioned into openings in the intake manifold just above the intake valve ports of the cylinder head. The engine wiring harness connector for each fuel injector is equipped with an attached numerical tag (INJ 1, INJ 2 etc.). This is used to identify each fuel injector. The injectors are energized individually in a sequential order by the powertrain control module (PCM). The PCM will adjust injector pulse width by switching the ground path to each individual injector on and off. Injector pulse width is the period of time that the injector is energized. The PCM will adjust injector pulse width based on various inputs it receives. During start up, battery voltage is supplied to the injectors through the ASD relay. When the engine is operating, voltage is supplied by the charging system. The PCM determines injector pulse width based on various inputs. Fuel Injectors - Typical FUEL INJECTORS- PCM OUTPUT The fuel injectors are attached to the fuel rail. 3.9L V-6 engines use six injectors. 5.2/5.9L V-8 engines use eight injectors. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Injector > Component Information > Specifications > Page 2694 The nozzle ends of the injectors are positioned into openings in the intake manifold just above the intake valve ports of the cylinder head.

The regulator is calibrated to maintain fuel system operating pressure of approximately 339 kPa ± 34 kPa (49.2 psi ± 5 psi) at the fuel injectors. It contains a diaphragm, calibrated springs and a fuel return valve. The internal fuel filter is also part of the assembly. Fuel is supplied to the filter/regulator by the electric fuel pump through an opening tube at the bottom of filter/regulator. The regulator acts as a check valve to maintain some fuel pressure when the engine is not operating. This will help to start the engine. A second check valve is located at the outlet end of the electric fuel pump. Refer to Fuel Pump-Description and Operation for more information. Also refer to the Fuel Pressure Leak Down Test and the Fuel Pump Pressure Tests. If fuel pressure at the pressure regulator exceeds approximately 49.2 psi, an internal diaphragm opens and excess fuel pressure is routed back into the tank through the bottom of pressure regulator.

Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine off) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1-2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: - Fuel pressure bleeding past a fuel injector(s). - Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose. Tool number 6539 is used for 5/16" fuel lines and tool number 6631 is used for 3/8" fuel lines. Connecting Adapter Tool-Typical Connecting Adapter Tool-Typical 3. Connect correct Fuel Line Pressure Test Adapter Tool Hose between disconnected fuel line and fuel rail. 4. Connect the 0-414 kPa (0-60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pump > Fuel Pressure > System Information > Specifications > Page 2725 6. Observe test gauge. Normal operating pressure should be 339 kPa ± 34 kPa (49.2 psi ± 5 psi). 7. Shut engine off. 8. Pressure should not fall below 30 psi for five minutes. 9. If pressure falls below 30 psi, it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine off. 12. Testing for fuel injector or fuel rail leakage: Clamp off the rubber hose portion of Adaptor Tool between the fuel rail and the test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a fuel injector or the fuel rail is leaking. 13. Testing for fuel pump check valve, filter/regulator check valve or fuel tube/line leakage: Clamp off the rubber hose portion of Adaptor Tool between the vehicle fuel line and test port "T" on Adapter Tool. If pressure now holds at or above 30 psi, a leak may be found at a fuel tube/line. If no leaks are found at fuel tubes or lines, one of the check valves in either the electric fuel pump or filter/regulator may be leaking. Note: A quick loss of pressure usually indicates a defective check valve in the filter/regulator. A slow loss of pressure usually indicates a defective check valve in the electric fuel pump. The electric fuel pump is not serviced separately. Replace the fuel pump module assembly. The filter/ regulator may be replaced separately on certain applications.

The sending unit consists of a float, an arm, and a variable resistor (track). The resistor track is used to send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for OBD II emission requirements. For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and arm move down. This increases the sending unit resistance causing the fuel gauge to read empty. After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading. For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the sending unit to the PCM to indicate fuel level. The purpose of this feature is to prevent the OBD II system from recording/setting false misfire and fuel system monitor trouble codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will also be activated if the fuel level in the tank is more than approximately 85 percent of its rated capacity.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 2819 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures.

With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT). At idle, TPS output voltage should be greater than 0.26 volts but less than 0.95 volts. At wide open throttle, TPS output voltage must be less than 4.49 volts. The output voltage should increase gradually as the throttle plate is slowly opened from idle to WOT. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Sensors and Switches - Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 2820 Throttle Position Sensor: Service and Repair REMOVAL The TPS is located on side of throttle body. 1.

The TPS is a variable resistor that provides the powertrain control module (PCM) with an input signal (voltage) that represents throttle blade position. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance of the TPS changes. The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 2840 Throttle Position Sensor: Testing and Inspection To perform a complete test of the TPS and its circuitry, refer to the DRB scan tool and appropriate Powertrain Diagnostics Procedures. To test the TPS only, refer to the following: TPS The TPS can be tested with a digital voltmeter. The center electrical terminal of the TPS is the output terminal. With the ignition key in the ON position, check the TPS output voltage at the center terminal wire of the connector. Check this at idle (throttle plate closed) and at wide open throttle (WOT). At idle, TPS output voltage should be greater than 0.26 volts but less than 0.95 volts. At wide open throttle, TPS output voltage must be less than 4.49 volts. The output voltage should increase gradually as the throttle plate is slowly opened from idle to WOT. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Throttle Position Sensor > Component Information > Specifications > Page 2841 Throttle Position Sensor: Service and Repair REMOVAL The TPS is located on side of throttle body. 1.

The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Camshaft Position Sensor-Typical (Distributor Shown) CAMSHAFT POSITION SENSOR-PCM INPUT A sync signal is provide by the camshaft position sensor. The sensor located in the distributor on all engines. The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs.

To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain Diagnostics Procedures service manual. To test the sensor only, refer to the following: For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips. 1. Connect the positive (+) voltmeter lead into the sensor output wire. This is at done the distributor wire harness connector. 2. Connect the negative (-) voltmeter lead into the ground wire. 3. Set the voltmeter to the 15 Volt DC scale. 4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup. 5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 6. If voltage is not present, check the voltmeter leads for a good connection. 7. If voltage is still not present, check for voltage at the supply wire. 8. If 5 volts is not present at supply wire, check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for this test. 9. If voltage is still not present, perform vehicle test using the DRB scan tool. 10. If voltage is present at cavity A-17, but not at the supply wire: a. Check continuity between the supply wire. This is checked between the distributor connector and cavity A-17 at the PCM. If continuity is not present, repair the harness as necessary. b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the PCM. If continuity is not present, repair the harness as necessary. c. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary. 11. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. If sync pulse signal is not present, replacement of the camshaft position sensor is necessary. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Camshaft Position Sensor > Component Information > Locations > Page 2856 Camshaft Position Sensor: Service and Repair Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines.

The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing. The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it. Sensor Operation The flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its outer edge. The notches cause a pulse to be generated when they pass under the sensor. The pulses are the input to the PCM. For each engine revolution, there are 8 pulses generated. The engine will not operate if the PCM does not receive a crankshaft position sensor input. CRANKSHAFT POSITION SENSOR-PCM INPUT This sensor is a hall effect device that detects notches in the flywheel (manual transmission) or flexplate (automatic transmission).

These cables transfer electrical current from the ignition coil(s) and/or distributor, to individual spark plugs at each cylinder. The resistive spark plug cables are of nonmetallic construction. The cables provide suppression of radio frequency emissions from the ignition system. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Cable > Component Information > Technical Service Bulletins > Page 2900 Ignition Cable: Testing and Inspection Check the spark plug cable connections for good contact at the coil(s), distributor cap towers, and spark plugs. Terminals should be fully seated. The insulators should be in good condition and should fit tightly on the coil, distributor and spark plugs. Spark plug cables with insulators that are cracked or torn must be replaced. Clean high voltage ignition cables with a cloth moistened with a non-flammable solvent. Wipe the cables dry. Check for brittle or cracked insulation. Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each spark plug cable boot and spark plug. These shields protect the spark plug boots from damage (due to intense engine heat generated by the exhaust manifolds) and should not be removed. After the spark plug cable has been installed, the lip of the cable boot should have a small air gap to the top of the heat shield. Testing When testing secondary cables for damage with an oscilloscope, follow the instructions of the equipment manufacturer. If an oscilloscope is not available, spark plug cables may be tested as follows: CAUTION: Do not leave any one spark plug cable disconnected for longer than necessary during testing. This may cause possible heat damage to the catalytic converter. Total test time must not exceed ten minutes. With the engine running, remove spark plug cable from spark plug (one at a time) and hold next to a good engine ground. If the cable and spark plug are in good condition, the engine rpm should drop and the engine will run poorly. If engine rpm does not drop, the cable and/or spark plug may not be operating properly and should be replaced. Also check engine cylinder compression. With the engine not running, connect one end of a test probe to a good ground. Start the engine and run the other end of the test probe along the entire length of all spark plug cables. If cables are cracked or punctured, there will be a noticeable spark jump from the damaged area to the test probe. The cable running from the ignition coil to the distributor cap can be checked in the same manner. Cracked, damaged or faulty cables should be replaced with resistance type cable. This can be identified by the words ELECTRONIC SUPPRESSION printed on the cable jacket. Use an ohmmeter to test for open circuits, excessive resistance or loose terminals. If equipped, remove the distributor cap from the distributor. Do not remove cables from cap. Remove cable from spark plug. Connect ohmmeter to spark plug terminal end of cable and to corresponding electrode in distributor cap. Resistance should be 250 to 1000 Ohms per inch of cable. If not, remove cable from distributor cap tower and connect ohmmeter to the terminal ends of cable. If resistance is not within specifications as found in the SPARK PLUG CABLE RESISTANCE chart, replace the cable. Test all spark plug cables in this manner. SPARK PLUG CABLE RESISTANCE MINIMUM = MAXIMUM 250 Ohms Per Inch = 1000 Ohms Per Inch 3000 Ohms Per Foot = 12,000 Ohms Per Foot To test ignition coil-to-distributor cap cable, do not remove the cable from the cap. Connect ohmmeter to rotor button (center contact) of distributor cap and terminal at ignition coil end of cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, remove the cable from the distributor cap. Connect the ohmmeter to the terminal ends of the cable. If resistance is not within specifications as found in the Spark Plug Cable Resistance chart, replace the cable. Inspect the ignition coil tower for cracks, burns or corrosion. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Cable > Component Information > Technical Service Bulletins > Page 2901 Ignition Cable: Service and Repair REMOVAL AND INSTALLATION Cable Removal CAUTION: When disconnecting a high voltage cable from a spark plug or from the distributor cap, twist the rubber boot slightly (1/2 turn) to break it loose. Grasp the boot (not the cable) and pull it off with a steady, even force. Engine Firing Order Install cables into the proper engine cylinder firing order. When replacing the spark plug and coil cables, route the cables correctly and secure in the proper retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could also cause cross ignition of the plugs or short circuit the cables to ground. When installing new cables, make sure a positive connection is made. A snap should be felt when a good connection is made between the plug cable and the distributor cap tower. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Specifications > Electrical Specifications Ignition Coil: Electrical Specifications Coil Manufacturer Diamond Primary Resistance 0.97 - 1.18 ohms at 21-27 deg C Secondary Resistance 11,300 - 15,300 ohms at 21-27 deg C Toyodenso Primary Resistance 0.95 - 1.20 ohms at 21-27 deg C Secondary Resistance 11,300 - 13,300 ohms at 21-27 deg C Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Specifications > Electrical Specifications > Page 2906 Ignition Coil: Mechanical Specifications Coil To Coil Bracket Nuts and Bolts 11 Nm Ignition Coil Bolts 5 Nm Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Specifications > Page 2907 Ignition Coil: Locations Ignition Coil The ignition coil is located near the front of the right cylinder head. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Specifications > Page 2908 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Specifications > Page 2909 Ignition Coil: Service Precautions WARNING: DO NOT REMOVE THE COIL MOUNTING BRACKET-TO-CYLINDER HEAD MOUNTING BOLTS.THE COIL MOUNTING BRACKET IS UNDER ACCESSORY DRIVE BELT TENSION.

The Powertrain Control Module (PCM) opens and closes the ignition coil ground circuit for ignition coil operation. Base ignition timing is not adjustable on any engine. By controlling the coil ground circuit, the PCM is able to set the base timing and adjust the ignition timing advance. This is done to meet changing engine operating conditions. The ignition coil is not oil filled. The windings are embedded in an epoxy compound. This provides heat and vibration resistance that allows the ignition coil to be mounted on the engine. IGNITION COIL- PCM OUTPUT System voltage is supplied to the ignition coil positive terminal. The powertrain control module (PCM) operates the ignition coil. Base (initial) ignition timing is not adjustable. The PCM adjusts ignition timing to meet changing engine operating conditions. Ignition Coil The ignition coil is located near the front of the right cylinder head. Refer to Ignition System for additional information. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Specifications > Page 2911 Ignition Coil: Testing and Inspection To perform a complete test of the ignition coil and its circuitry, refer to the DRB scan tool. Also refer to the appropriate Powertrain Diagnostics Procedures. To test the coil only, refer to the following: Ignition Coil - Typical (5.2/5.9L) The ignition coil is designed to operate without an external ballast resistor.

Test the coil according to coil tester manufacturer's instructions. Test the coil primary and secondary resistance. Replace any coil that does not meet specifications. Refer to the IGNITION COIL RESISTANCE chart. If the ignition coil is being replaced, the secondary spark plug cable must also be checked. Replace cable if it has been burned or damaged. Arcing at the tower will carbonize the cable boot, which if it is connected to a new ignition coil, will cause the coil to fail. If the secondary coil cable shows any signs of damage, it should be replaced with a new cable and new terminal. Carbon tracking on the old cable can cause arcing and the failure of a new ignition coil. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Ignition Coil > Component Information > Specifications > Page 2912 Ignition Coil: Service and Repair The ignition coil is an epoxy filled type. If the coil is replaced, it must be replaced with the same type. REMOVAL Ignition Coil The coil is mounted to a bracket that is bolted to the front of the right engine cylinder head. This bracket is mounted on top of the automatic belt tensioner bracket using common bolts. 1. Disconnect the primary wiring from the ignition coil. 2.

The sensor contains a hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. Camshaft Position Sensor-Typical (Distributor Shown) CAMSHAFT POSITION SENSOR-PCM INPUT A sync signal is provide by the camshaft position sensor. The sensor located in the distributor on all engines. The sync signal from this sensor works in conjunction with the crankshaft position sensor to provide the powertrain control module (PCM) with inputs.

To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain Diagnostics Procedures service manual. To test the sensor only, refer to the following: For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips. 1. Connect the positive (+) voltmeter lead into the sensor output wire. This is at done the distributor wire harness connector. 2. Connect the negative (-) voltmeter lead into the ground wire. 3. Set the voltmeter to the 15 Volt DC scale. 4. Remove distributor cap from distributor (two screws). Rotate (crank) the engine until the distributor rotor is pointed towards the rear of vehicle. The movable pulse ring should now be within the sensor pickup. 5. Turn ignition key to ON position. Voltmeter should read approximately 5.0 volts. 6. If voltage is not present, check the voltmeter leads for a good connection. 7. If voltage is still not present, check for voltage at the supply wire. 8. If 5 volts is not present at supply wire, check for voltage at PCM 32-way connector (cavity A-17). Leave the PCM connector connected for this test. 9. If voltage is still not present, perform vehicle test using the DRB scan tool. 10. If voltage is present at cavity A-17, but not at the supply wire: a. Check continuity between the supply wire. This is checked between the distributor connector and cavity A-17 at the PCM. If continuity is not present, repair the harness as necessary. b. Check for continuity between the camshaft position sensor output wire and cavity A-18 at the PCM. If continuity is not present, repair the harness as necessary. c. Check for continuity between the ground circuit wire at the distributor connector and ground. If continuity is not present, repair the harness as necessary. 11. While observing the voltmeter, crank the engine with ignition switch. The voltmeter needle should fluctuate between 0 and 5 volts while the engine is cranking. This verifies that the camshaft position sensor in the distributor is operating properly and a sync pulse signal is being generated. If sync pulse signal is not present, replacement of the camshaft position sensor is necessary. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Sensors and Switches - Ignition System > Camshaft Position Sensor > Component Information > Locations > Page 2920 Camshaft Position Sensor: Service and Repair Camshaft Position Sensor - Typical The camshaft position sensor is located in the distributor on all engines.

The sensor generates pulses that are the input sent to the Powertrain Control Module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing. The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it. Sensor Operation The flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its outer edge. The notches cause a pulse to be generated when they pass under the sensor. The pulses are the input to the PCM. For each engine revolution, there are 8 pulses generated. The engine will not operate if the PCM does not receive a crankshaft position sensor input. CRANKSHAFT POSITION SENSOR-PCM INPUT This sensor is a hall effect device that detects notches in the flywheel (manual transmission) or flexplate (automatic transmission). This sensor is used to indicate to the powertrain control module (PCM) that a spark and or fuel injection event is to be required. The output from this sensor, in conjunction with the camshaft position sensor signal, is used to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders.

Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken porcelain insulators. Keep plugs arranged in the order in which they were removed from the engine. A single plug displaying an abnormal condition indicates that a problem exists in the corresponding cylinder. Spark plugs that have low milage may be cleaned and reused if not otherwise defective, carbon or oil fouled. Refer to the Spark Plug Condition. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2943 Spark Plug: Testing and Inspection SPARK PLUG CONDITIONS Normal Operation And Cold (Carbon) Fouling NORMAL OPERATING The few deposits present on the spark plug will probably be light tan or slightly gray in color. This is evident with most grades of commercial gasoline. There will not be evidence of electrode burning. Gap growth will not average more than approximately 0.025 mm (0.001 in) per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be cleaned, have the electrodes filed, have the gap set and then be installed. Some fuel refiners in several areas of the United States have introduced a manganese additive (MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits. COLD FOULING/CARBON FOULING Cold fouling is sometimes referred to as carbon fouling. The deposits that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set of spark plugs may be caused by a clogged air cleaner element or repeated short operating times (short trips). WET FOULING OR GAS FOULING A spark plug coated with excessive wet fuel or oil is wet fouled. In older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the fouled plugs. Oil Or Ash Encrusted OIL OR ASH ENCRUSTED Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2944 If one or more spark plugs are oil or oil ash encrusted, evaluate engine condition for the cause of oil entry into that particular combustion chamber. Electrode Gap Bridging ELECTRODE GAP BRIDGING Electrode gap bridging may be traced to loose deposits in the combustion chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving. When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap bridging can be cleaned using standard procedures. Scavenger Deposits SCAVENGER DEPOSITS Fuel scavenger deposits may be either white or yellow. They may appear to be harmful, but this is a normal condition caused by chemical additives in certain fuels. These additives are designed to change the chemical nature of deposits and decrease spark plug misfire tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in condition and can be cleaned using standard procedures. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2945 Chipped Electrode Insulator CHIPPED ELECTRODE INSULATOR A chipped electrode insulator usually results from bending the center electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation can also separate the insulator from the center electrode. Spark plugs with this condition must be replaced. Preignition Damage PREIGNITION DAMAGE Preignition damage is usually caused by excessive combustion chamber temperature. The center electrode dissolves first and the ground electrode dissolves somewhat latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat range rating for the engine. Determine if ignition timing is over advanced or if other operating conditions are causing engine overheating. (The heat range rating refers to the operating temperature of a particular type spark plug. Spark plugs are designed to operate within specific temperature ranges. This depends upon the thickness and length of the center electrodes porcelain insulator.) Spark Plug Overheating SPARK PLUG OVERHEATING Overheating is indicated by a white or gray center electrode insulator that also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause spark plug overheating. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2946 Spark Plug: Service and Repair Heat Shields Spark plug cable heat shields are pressed into the cylinder head to surround each cable boot and spark plug. If removal of the heat shield(s) is necessary,remove the spark plug cable and compress the sides of shield for removal. Each shield is slotted to allow for compression and removal. To install the shields, align shield to machined opening in cylinder head and tap into place with a block of wood. PLUG REMOVAL Cable Removal 1. Always remove spark plug or ignition coil cables by grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight back in a steady motion. Never pull directly on the cable. Internal damage to cable will result. 2. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area around the spark plug. This will help prevent foreign material from entering the combustion chamber. 3. Remove the spark plug using a quality socket with a rubber or foam insert. 4. Inspect the spark plug condition. Refer to Spark Plug Condition in the Diagnostics and Testing. PLUG CLEANING The plugs may be cleaned using commercially available spark plug cleaning equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before adjusting gap. CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will remain on the spark plug insulator and will cause plug misfire. PLUG GAP ADJUSTMENT Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information > Specifications > Page 2947 Setting Spark Plug Gap - Typical Check the spark plug gap with a gap gauge tool. If the gap is not correct, adjust it by bending the ground electrode. Never attempt to adjust the gap by bending the center electrode. SPARK PLUG GAP 1.01 mm (0.040 in) PLUG INSTALLATION Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged. Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator. When replacing the spark plug and ignition coil cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise. It could cause cross ignition of the spark plugs or short circuit the cables to ground. 1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. Tighten spark plugs to 35-41 N-m (26-30 ft. lbs.) torque. 3. Install spark plug cables over spark plugs. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Actuators and Solenoids Transmission and Drivetrain > Actuators and Solenoids - A/T > Pressure Regulating Solenoid, A/T > Component Information > Technical Service Bulletins > Customer Interest for Pressure Regulating Solenoid: > 21-08-99 > Apr > 99 > A/T - Buzz/Whining in Reverse When Cold Pressure Regulating Solenoid: Customer Interest A/T - Buzz/Whining in Reverse When Cold NUMBER: 21-08-99 GROUP: Transmission DATE: April 30, 1999 SUBJECT: "Buzz", "Whining", Or "Moaning" Like Noise From A Cold Transmission When Reverse Is Selected.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

The switch is a momentary contact device that signals the PCM to toggle current status of the overdrive function. At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a second time causes normal overdrive operation to be restored and the overdrive lamp to be turned off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The normal position for the control switch is the ON position. The switch must be in this position to energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only when the overdrive switch is turned to the OFF position, or when illuminated by the transmission control module. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Position Switch/Sensor, A/T > Component Information > Locations Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Position Switch/Sensor, A/T > Component Information > Locations > Page 3018 Transmission Position Switch/Sensor: Description and Operation TRANSMISSION PARK/NEUTRAL SWITCH-PCM INPUT The park/neutral switch is located on the transmission housing and provides an input to the powertrain control module (PCM).

The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs. The transmission will not allow fourth gear operation until fluid temperature decreases to approximately 110 °C (230 °F).

MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango 1999 (TJ) Wrangler 1999 (XJ) Cherokee 1999 (WJ) Grand Cherokee SYMPTOM/CONDITION: A Powertrain Control Module (PCM) software condition exists that can cause an erroneous engine miss to occur only when in certain screens of the Diagnostic Scan Tool (DRB III). The miss will not set a Malfunction Indicator Lamp (MIL), but may be felt and can be seen while performing diagnostics with the DRB III. This condition occurs only when using the DRB III to read Diagnostic Trouble Codes (DTC's), Secondary Indicators, or 1 Trip Failures and while driving the vehicle. This is more likely to occur during hard acceleration. While in these screens, a miss may be felt by the technician, or when in the Secondary Indicators or 1 Trip Failures screen an erroneous injector circuit failure can flash on the DRB III screen with an accompany beep from the DRB III. This condition may lead technicians to incorrectly diagnose a problem and may cause erroneous repairs that will not fix the vehicle. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the DRB III with the appropriate Diagnostic Procedures Manual, verify all engine/transmission systems are functioning as designed. If DTC's are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptoms have been experienced, perform the Repair Procedure. NOTE: WHENEVER A POWERTRAIN CONTROL MODULE (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION LEVEL.

DISCUSSION: Some states that require I/M inspections are beginning to include OBD II "CARB" Readiness as a prerequisite to an I/M test. OBD Readiness tells an I/M station if the OBD II systems have run their self test. Owners, in those states that use OBD Readiness, may be denied an I/M test if one or more of the Readiness monitors read "NO" or in other words the OBD II monitors have not run their tests. It is important to understand that the MIL will not be illuminated because OBD Readiness reads "NO". MIL illumination happens when an actual malfunction or failure of a monitored emissions system occurs. It is possible to have MIL illumination for a detected failure while at the same time having a "NO" for an OBO Readiness monitor. NOTE: MIL ILLUMINATION INDICATES ADDITIONAL PROBLEMS WITH THE VEHICLE. FURTHER DIAGNOSIS AND REPAIR WILL BE REQUIRED BEFORE PROCEEDING FURTHER WITH THIS BULLETIN. OBD Readiness that reads "NO" can be caused by the following: PCM reprogramming, PCM replacement, fault code erasure, battery disconnects and/or replacement. If any of the above items occur before an I/M test, a good chance exists that one or more of the monitors will read "NO" for OBD Readiness. Some customers may be directed back to their dealers for assistance when an I/M test station has not allowed an I/M test due to Readiness status. The following procedures will help technicians efficiently run the Readiness tests so an owner can have their I/M test completed.

FAILURE CODE: XX - Service Adjustment Repair Procedure This bulletin involves operating the vehicle under specific parameters to run or complete the OBD monitors. The number of monitors applicable to a vehicle will vary by type of vehicle and emissions application. In addition, the parameters to run each monitor will vary. Preliminary Checks 1. Perform a MIL bulb check by switching the ignition key "ON" (engine off). The MIL will illuminate as a bulb check. If the MIL does not illuminate, repair the bulb or bulb circuit. 2. Connect a DRB III(R) to the vehicle. Select DRB III(R) standalone, current model year diagnostics, engine, DTC's and related functions, read DTC's. 3. Verity that no emission related DTC's are present and that the MIL is not illuminated with the engine running. NOTE: EMISSION RELATED DTC'S AND MIL ILLUMINATION MAY PREVENT OTHER OBD MONITORS FROM RUNNING. DTC'S THAT ILLUMINATE THE MIL MUST BE REPAIRED BEFORE ATTEMPTING TO RUN THE MONITORS. OBD "CARB" Readiness Check 1. With the DRB III(R) select engine, OBD II monitors, CARB Readiness Status. 2. Read the monitor status. "YES" tells you that monitor has run and is ready for an I/M test, "NO" tells you that the monitor must be run. If all monitors listed read "YES", the vehicle can be returned to the customer for completion of their I/M test. Only monitors that read "NO" must be run to read "YES". NOTE: THE MONITORS LISTED IN THE OBD "CARB" READINESS SCREEN ARE THE ONLY ONES APPLICABLE FOR THE VEHICLE BEING WORKED ON. The vehicle must be operated in various conditions (speed, temperature, etc.) for the monitors to run. Each monitor includes a pre-test and monitor test that can be viewed on the DRB III(R). The pre-test/monitor test screen lists all the preliminary parameters that must be met along with the running parameters for that specific monitor to run. An example of one screen is shown in Figure 1. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > Customer Interest: > 25-02-98 > Oct > 98 > I/M Testing - OBDII CARB Readiness Monitor Information > Page 3078 NOTE: 1997 AND PREVIOUS MODEL VEHICLES WILL HAVE A DIFFERENT LOOKING SCREEN. PRESS THE F1 KEY TO OBTAIN MONITOR RUN CONDITIONS. THE WAY IN WHICH THE MONITORS RUN WILL BE SIMILAR. The following explains how to interpret each section of the screen: PRE-TEST REQUIREMENTS The pre-test requirements include all the operating parameters that must be met before the actual test can run. The vehicle must be operated until each item within the pre-test section are fulfilled. LOW VALUE/HIGH VALUE/BAR GRAPH The low value/high value provides the minimum and maximum operating conditions for each item (ie ECT Range must be between 170° and 260° F in Figure 1). The bar graph will begin to fill when the lowest value required for each item is met. This provides a visual indication that the parameters are being met. The vehicle should be driven until most of each pre-test bar graph is filled. MONITOR REQUIREMENTS Once all pre-test requirements are met, the vehicle must be brought within the parameters listed in the monitor requirements section for the monitors to begin running. As the monitor begins to run, the DRB III(R) will begin to beep. This is an audible indication that the test is in progress. If vehicle operation falls outside any of the parameters, the beeping will stop. If this occurs, the technician must determine if the pre-test requirements or the monitor requirements have fallen outside the window for the test and the vehicle must be driven accordingly for the test to restart. When the monitor completes its test, the DRB III(R) will beep 3 consecutive times. NOTE: THE PURGE FLOW PRE-TEST SCREEN WILL LOOK DIFFERENT THAN THE REST OF THE PRE-TEST/MONITOR SCREENS. PRESS THE F1 KEY ON THE DRB III(R) TO SEE A SIMILAR SCREEN FOR THIS MONITOR. MONITOR RUN PROCESS The following will provide the most efficient order along with tips to help run through the monitor tests quickly. The monitors listed include all possible monitors for either Front Wheel Drive or Rear Wheel Drive vehicles. The vehicle being worked on may have fewer monitors than the maximum available. Only those listed on the DRB III(R) are applicable for the vehicle being worked on. The only monitors that will require attention are those that read "NO" under the OBD "CARB" Readiness Status screen. Front Wheel Drive 1. Evaporative Leak Detection Monitor - This test will require a cold start (possibly an overnight soak either indoors or out depending on conditions). The ambient (outside) temperature must be between 4° and 32° C (40° and 90° F) with the engine coolant temperature within 6° C (10 ° F) of ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen on the DRB III(R) to determine the remaining requirements. 2. Catalyst Monitor - The vehicle must be driven at highway speeds for the time listed in the pre-test screen. If the vehicle is equipped with a manual transaxle, use fourth gear to help meet the requirements. 3. EGR Monitor - It is necessary to maintain TPS, MAP, and RPM ranges listed in the pre-test screen for this test to complete. 4. O2 Sensor Monitor - The vehicle must be driven and brought to a stop for the time listed in the pre-test screen. Automatic transaxle vehicles must be left in drive during the stop period. 5. Purge Monitor - To see a similar screen format as listed in Figure 1, press the F1 key on the DRB III(R) while in the Purge Flow Pre-Test screen. The purge free (PF) cells must update and the monitor will attempt to run on every other throttle closure. Automatic transaxle vehicles must be left in drive for the test to run. If all parameters are met and the test still will not run, place your foot on the brake, open the throttle to 1/4 and then quickly close the throttle. This should allow the PF cells to update. 6. O2 Sensor Heater Monitor - The open throttle time for the O2 Heater pre-test must be exceeded. This monitor will run after the ignition key is switched "Off". After the DRB III(R) switches to No Response (approximately 3 minutes) turn the ignition key "On" and check the O2 Sensor Heater monitor status. It should have switched to "YES". All other monitors should be completed before running this test. Rear Wheel Drive 1. O2 Sensor Heater Monitor - This test will require a cold start (possibly an overnight soak either indoors or outdoors depending on conditions). The ambient (outside) temperature must be between 18° and 38° C (0° and 100° F with the engine coolant temperature within 6° C (10° F) of ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen on the DRB III(R) to determine the remaining Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > Customer Interest: > 25-02-98 > Oct > 98 > I/M Testing - OBDII CARB Readiness Monitor Information > Page 3079 requirements. 2.

Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment may lock up or become disconnected during the procedure. Flash Reprogramming is a "CRITICAL PROCESS"; an error may result in a no-start/failed control module. Most modules, encountering an interruption or failure while reprogramming, are recoverable; a recoverable module is not covered under the provisions of the warranty. This service bulletin covers items that may cause this condition, a process to restart the flash procedure, and miscellaneous information that will help prevent needless replacement of control modules. GENERAL: Flash Reprogramming is only authorized by a specific SERVICE BULLETIN, or RECALL. Review the entire Service Bulletin/Recall prior to performing a flash reprogramming update. Often other parts may need to be serviced, replaced, or tested, prior to flash reprogramming, and ARE REQUIRED as part of completing the Service Bulletin/Recall. When flashing a Powertrain Control Module (PCM) or Transmission Control Module (TCM) there are other legal requirements with labeling issues that are included in those service bulletins. Other non-emission related modules, such as instrument clusters and Body Control Modules (BCMs) do not require labels. FLASH REPROGRAMMING SEQUENCE OF EVENTS The process of flash reprogramming is similar to flashing the BIOS on a Personal Computer. Interruptions, voltage problems, and a variety of other outside interactions can potentially interfere with the process. This document seeks to provide information to minimize problems associated with vehicle control module flash reprogramming. The description that follows is for most PCMs and some TCMs. Other modules use different initiation procedures. The process starts by selecting an update from the TechCONNECT Client or ISIS and then "loading" that update into the DRBIII(R). Once the flash reprogramming update is loaded into the DRBIII(R), and before the flash reprogramming begins, the DRBIII(R) verifies that the update loaded from the TechCONNECT Client or ISIS is the proper update for the module. This is done using part number supersedence. This verification occurs only if an update is required, available (on the TechCONNECT Client or ISIS) and has been selected for programming. ^ The module is then placed into "Boot Strap" programming mode by the DRBIII(R). This module mode gives the DRBIII(R) permission and the ability to proceed with the flash reprogramming session. ^ Next, the current part number, which resides in the module's flash memory, is stored in a "Safe Memory" location within the module. This memory location is not affected by flash memory erasure and reprogramming, which are to follow. ^ Once the part number is safely stored, the flash memory in the control module is erased. From this point forward any interruption in the flash process, Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3086 will result in a Non-Responsive module (NR). A NR module is a module that is either partially erased or partially programmed. ^ After erasure, the actual reprogramming procedure starts, and the update software is programmed into the flash memory within the module. ^ When reprogramming is completed, the flash memory is verified through an internal process in the DRBIII(R) using a "Check Sum". This value is compared against another value that represents what should be in memory and when matched, verifies successful reprogramming. ^ Next, a DRBIII(R) prompt is displayed instructing that the ignition switch be turned OFF. The module exits the "Boot Strap" mode when the switch is turned off. ^ After a slight pause, the DRBIII(R) will prompt for the ignition switch to be turned ON. The DRBIII(R) then reads the new part number in flash memory (along with a new computer program the new part number is placed into the module's memory). If the new part number matches the expected part number, the flash reprogramming session has completed successfully. SOFTWARE VERSIONS MUST BE CURRENT Before attempting a flash reprogramming session using the TechCONNECT Client, make sure you have the most current DRBIII(R) software installed. To verify whether your DRBIII(R) software is current, check the upper right-hand corner of the TechCONNECT Client screen for DRBIII(R) Available Version, DRBIII(R) Current Version. Often, because of multiple DRBIII(R)s in the shop, not all will get updated on a timely manner. The installed DRBIII(R) software version can generally be found at the bottom center of most screens. Alternately the version can be checked by pressing 6, 2, 5 from the DRBIII(R) Main Menu and comparing it to what is available from a current TechCONNECT Client as described above. If the TechCONNECT Client is current and the DRBIII(R) is not, it may be due to the fact that the TechCONNECT Client does not force DRBIII(R) updates for "minor" revisions. Changes and new support are added to the Vehicle Flash application on "minor" revisions on a regular basis. This is why your TechCONNECT Client and DRBIII(R) must have the LATEST software revisions installed. DO NOT PASS on the option for updating to a "minor" revision! Major updates require the DRBIII(R) to be updated prior to allowing any flash programming. DRBIII(R) CABLES A NEW DRBIII(R) cable was released as an Essential Service Tool! CH7000A - 8 ft. Cable, DRBIII(R) to OBDII (J1962) DLC Connector. CH7000A is the required cable for ALL flash reprogramming. The older CH7000 cable can be used for diagnostics ONLY. One (1) cable was shipped to all dealerships. Easily identified, the correct cable has a RED connector, which plugs into the DRBIII(R). The cable modification enhances the DRBIII(R) communication capabilities when dealing with the flash requirements of certain controllers/ECUs affected in part by the recent changes in DLC connector configurations. The new cable is required for ALL flash reprogramming sessions, and can be used wherever the previous CH700017001 cables were used. While not recommended for flash reprogramming usage, if you require a longer cable, there is also a 12-foot cable released under pin CH7001A The production of the previous CH700017001 cables has ceased. All orders placed will be superseded to part number CH7000A/CH7001A. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3087 NOTE: Consider all cables wear items. Always inspect for worn, damaged cables, connectors that are damaged or do not lock securely, and all mating connections including checking for corrosion on the pins. REPLACE ALL suspect cables. Do not use worn or damaged cables when flash reprogramming. Failure to use the new cable or to use a damaged cable often results in failed flash reprogramming sessions. The 2 door Sebring, Stratus, and Avenger coupes (supplied by MMC) generally use the CH7O1O cable (Pre-OBDII MMC vehicles will use the CH7005 cable). TechCONNECT CABLE (GPIB) Replace any suspect GPIB cable. The GPIB cable provides the connection between TechCONNECT Client and the DRBIII(R). This cable is used by the TechCONNECT Client for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes disconnected during a flash session, you may have to reload the update file that you selected on the TechCONNECT Client. TROUBLESHOOTING CONNECTIVITY OF THE DRBIII(R) UNIT TO THE TechCONNECT APPLICATION. 1. Turn-on the power to the DRBIII(R) unit. 2. Select option 2 "Connect to TechCONNECT" and press Enter. 3. Attach the male mini D-shell amphenol GPIB connector of the new DRBIII(R) cable (part number CH7035B) to the DRBIII(R) unit. 4. Insure that the larger female D-shell amphenol GPIB connector of the new DRBIII(R) cable is properly attached to the male D-shell amphenol GPIB connector on the GPIB-USB-B protocol converter, (part number CHGPIB-B). 5. Attach the USB cable from the GPIB-USB-B protocol converter to one of the USB ports on the rear panel of the client CPU. 6. When the cable is attached to the USB port of the CPU for the first time, Windows 2000 will detect the device and install software for it. Please wait for 25-30 seconds to complete the installation. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3088 ISIS NULL MODEM CABLE Replace any suspect null modem cables. International (ISIS), a PC-based CD program similar to TechCONNECT Client uses a null modem cable for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes disconnected during a flash download session, you will have to reload the update file or files. GENERAL NOTES FOR CABLES AND VEHICLE CONNECTIONS Consider ALL cables to be wear items. Many successful dealers have dedicated cables devoted to "Flash ONLY". Always have spare CH7000A, CH7010 and CH2002 GPIB or null modem cables available. Inspect vehicle diagnostic connectors for potential problems that might cause communication interruptions. There are now clip repair kits available through teamPSE to replace the retaining clips for two of these cables. To protect the DRBIII(R) from internal damage, the clips are designed to fail at above 25 lbs. of axial force. Kits are described in the table. It is a good practice to discard cables that have damage to the pins, cuts, corrosion, or general damage beyond the retaining clips. ST22 SEBRING STRATUS 2 DOOR COUPES (2001-2005) Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3089 These vehicles use MMC based modules. The CH8432 Supplemental Reprogramming Tool (SRT) was shipped as a 2001 Essential Tool. The flash reprogramming update files will be downloaded from TechCONNECT Client to the SRT for flash reprogramming sessions on these vehicles. Users should closely follow the instructions that come with the tool. If the tool has not been initialized, there is a known condition where it may take up to 5 or more attempts for it to fully initialize and become functional. NOTE: Once it has successfully flashed, it is initialized and no further action is required. PREPARING TO FLASH It is highly recommended that a sign, or other process, be used that notifies other users that a FLASH SESSION IS IN-PROGRESS and must NOT be interrupted. Interrupting some flash reprogramming sessions at critical junctures can render a module inoperative. Another user may not realize that a flash session is in-progress and may disturb or disconnect the DRBIII(R) or do something on the vehicle that could interrupt the flash process. Before starting the flash session, read, record and erase all DTCs found on the vehicle. Also "Cold Boot" the DRBIII(R) and download the flash since this will erase the flash file from the DRBIII(R) memory. (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press "F4"). Be sure to arrange the TechCONNECT and DRBIII(R) so that no cables are stretched across an area where someone might trip over or kick a cable. When setting up your DRBIII(R), insure that it rests on a surface where it will not fall or be bumped during reprogramming e.g.: DRBIII's have been known to be swept off vehicle windshields by accident when a user bumps the wiper switch). Check User settings on the DRBIII(R). From the DRBIII(R) Main menu, press 6,1 and check to make sure item 1. Echo on PC is set to OFF. On occasion, when Echo on PC is set to ON, flash reprogramming errors may occur. VEHICLE BATTERY VOLTAGE The flash programming procedure puts a load on the electrical system that may last from five to twenty minutes depending on the particular flash reprogramming update. Connect a battery charger to the vehicle. Set the charger to as close to 14 volts as possible. If the charger has a timer, set it for 30 minutes BEFORE starting a flash reprogramming session. This will help to prevent unwanted resets by either the DRBIII(R) and/or the vehicle module that are caused by voltage fluctuations. Alternately, as a bare minimum, use a "Battery Jump Box" when a battery charger is unavailable to ensure adequate and stable system voltages on the module being flash reprogrammed. POLICY: Information Only Disclaimer: This bulletin is supplied as technical information only and is not an authorization for repair. Connected/Disconnected Flash Mode Using TechCONNECT CONNECTED MODE FLASHING USING TechCONNECT NOTE: Capable but not recommended. In this mode, the DRBIII(R) remains connected to the TechCONNECT Client and the vehicle throughout the flash session. The DRBIII(R) is connected to the TechCONNECT Client using the GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the CH7000A for most vehicles). This mode is useful when the TechCONNECT Client is next to the vehicle being flashed. Another advantage of this mode is that you are able to determine all available flash updates for the vehicle you are connected to by clicking on the "Read Part Number(s) From Vehicle" button. Again, it is important that other users do not attempt to reboot or move the TechCONNECT Client while a flash update is in-progress. The reprogramming procedure of this mode is initiated by selecting the controller option and clicking "Download/Update" button on the TechCONNECT client. DISCONNECTED FLASH MODE NOTE: Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3090 This is the preferred method. This mode allows a user to flash a vehicle without being connected to the TechCONNECT Client. This is a popular mode for flashing in a remote area of the service garage or in a back lot. Before you attempt to use this mode, you must configure the DRBIII(R) for the desired update(s). To do this, you must connect the DRBIII(R) to the TechCONNECT Client using the GPIB cable and the CH7025 cable. It is not necessary to be connected to a vehicle. The GPIB (CH7035) cable will be used to communicate with the TechCONNECT Client (for update file downloading) while the CH7025 cable is used to provide power to the DRBIII(R). After making the above connections, you are able to select one or more updates that you want to perform. These selections are made by highlighting the desired updates and then clicking on the "Download/Update" button by selecting the DRBIII(R) option on the TechCONNECT client. Obviously, the DRBIII(R) does not have unlimited memory. If the file size of the selected updates exceeds 948 KB, the "DRB Space Used" indicator (at the bottom-center of the TechCONNECT Client screen) will change color from GREEN to RED. At this point you must de-select entries until the indicator changes color to GREEN again. When the updates have finished downloading, you may disconnect from the TechCONNECT Client and take the DRBIII(R) to wherever the vehicle is located. The updates will remain in DRBIII(R) memory for 8 hours while the DRBIII(R) is without power. If the DRBIII(R) is powered up for several minutes before the 8 hour time period has expired, the update files will remain on the DRBIII(R) for another 8 hours without power. To start the actual flash process, after connecting to the vehicle in Disconnected Mode, you must press "7 - Vehicle Flash" from the Main Menu on the DRBIII(R). Step by step instruction will follow on the DRBIII(R) display. As with Connected Flash Mode, take the necessary precautions to insure that others are aware of the flash session and that nothing disturbs the vehicle, DRBIII(R), or cabling while performing the flash. Remember to use a battery charger set to 14 volts or a "battery jump box". Pay Attention While Performing Flash Reprogram Procedures PAY ATTENTION WHILE PERFORMING FLASH REPROGRAMMING PROCEDURES Before downloading the flash files, double check to see if the files that you have selected are the appropriate ones for that vehicle. Don't forget about the "Read Part Numbers From Vehicle" option on TechCONNECT Client, this can be of great assistance when trying to flash a module. If the files selected don't download on the first attempt, try again. The technician should NOT leave the vehicle when flash reprogramming a module. Again, check to make sure that all cable connections are secure and that the DRBIII(R) rests on a stable surface. If you are using a battery charger, insure that the settings and charging times are correct and that the battery post clamps are securely fastened. Read, record, and erase all DTCs found on the vehicle. Read and record the module type and part number from the module that is to be flash reprogrammed. Some control modules are not "abort-recovery" capable. When this is true, the scan tool will indicate so by displaying a WARNING message prior to the start of reprogramming. For these modules it is especially important that all precautions and procedures, outlined here, are carefully followed. Pay special attention to DRBIII(R) screen directions relating to key cycles. Missing a "Key ON" or "Key OFF" can cause the module to have to be reflashed again. Due to the variety of module types and vehicle options, you can't always anticipate key prompts, so be alert and ready to respond to DRBIII(R) instructions. Some screens will also instruct that certain modules, connectors or fuses be disconnected or pulled prior to the start of reprogramming and re-installed immediately after completion. Be careful not to anticipate the steps or order of operations for reprogramming any vehicle modules. Because of the many possible changes that occur with each new release of scan tool software, always allow the TSB/Recall and scan tool instructions to be your guide while performing flash reprogramming. Flash reprogramming sessions usually range from 5 to 20 minutes. If the flash session has not completed within 25 minutes after starting a flash reprogramming update, an error has most likely occurred (Record the message that appears on the screen when a failure occurs). If this is the case, or if you know that the flash process was interrupted, cycle the ignition key (OFF to the locked position, then back ON). Reset the DRBIII(R) (power down for 4 seconds and then power up) before attempting to restart the flash process. If the module still won't respond, turn the ignition key off, disconnect the module from the vehicle for 2 minutes, reconnect the module, turn the ignition key to run and try to restart the flash process again. Regardless of what mode that you are in (Connected Flash or Disconnected Flash), if you have tried twice (2 times) unsuccessfully to do a flash recovery and ALL DRBIII(R) instructions were followed, perform the following: ^ Cold boot the DRBIII(R). This resets memory and removes all update files from the DRBIII(R). (Push MORE and YES buttons at the same time, then press F4). ^ Reload the flash update file from the TechCONNECT Client. ^ If it fails to complete in the connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to the DRBIII(R). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3091 ^ Proceed to reflash the module. On vehicles that have multiple flash updates available, always complete and verify each flash update before attempting the next one. After all flash reprogramming is completed, read and erase all DTCs in all modules on the vehicle. A variety of DTCs may be set, which are usually related to a loss of communication with the module(s) being reprogrammed. Verify the update by reading the new part number using the DRBIII(R). A good double check is to read the part number using DRBIII(R) stand alone. At times, other modules, wired in parallel, to the DLC connector have prevented flash reprogramming sessions to be successful. After the failed attempt, review the appropriate wiring diagram for the vehicle you are flash reprogramming and, with the key "OFF"; disconnect the other modules and retry the flash. Complete the flash, turn the key "OFF" and reconnect any modules that were disconnected. Refer to the "Programmable Modules" section later in this document for more information. Error Messages ERROR MESSAGES Block Echo/Compare Errors Block Echo and Block Compare errors are often caused by voltage fluctuations, faulty I/O cables (CH7OOOA, CH7005, CH7010) or faulty communication connections at the diagnostic connector. Inspect for these conditions and review the sections on Vehicle Battery Voltage and Cable recommendations. Checksum Errors Checksum Errors are generally caused by corrupt flash update files, which can be caused by DRBIII(R) memory problems. If the DRBIII(R) has been without power for more than 8 hours, the update files and system memory could be in a corrupted state. "Cold Boot" the DRBIII(R). (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press "F4"). Reload the flash update file(s) from the TechCONNECT CLIENT. If it fails to complete in the connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to the DRBIII(R). Then re-attempt the flash reprogramming process. Enhanced and Original Abort Recovery ENHANCED ABORT RECOVERY Interruptions in the flash process are one of the main reasons for failed flash sessions and non-responsive (NR) modules. Interrupting the flash process after the erase phase has started will leave the control module in a non-functional state. Generally, but not always, NR modules may be recovered successfully. Briefly, abort recovery is the process used to get a NR module back to a fully functional state with the latest software update. The technician should be familiar with the other sections in this document and follow all DRBIII(R) user prompts carefully. There are two methods for abort-recovery. The newer method is called "Enhanced Abort Recovery". This is the preferred method since the original method takes several minutes longer and requires the correct selection of module type from a list of possible PCM's or TCM's. Starting with Release 60.1, a new useful feature was added to the flash reprogramming application for Engine and Transmission control modules. The DRBIII(R) "writes" the YME and Controller Type information to a "Safe Memory" location. This method allows for rapid recovery of the module part number and minimizes errors that could otherwise be made by selecting the wrong controller type. It also assumes that the user will attempt abort recovery for a failed flash attempt before moving to another vehicle with the same DRBIII(R). If you need to move to another vehicle for flash reprogramming you must erase the saved recovery information in order to successfully perform flash reprogramming. Be careful to match the YME information displayed on the enhanced abort recovery screen with the vehicle and module that you are attempting to recover. If you use the recovery file on a different vehicle and module you could damage the module. The recovery information will be displayed on your DRBIII(R), at the start of a flash session, only if you previously encountered a problem that prevented a flash session from completing normally. If your prior flash session was successful, the DRBIII(R) automatically erases the recovery file so that the flash application will not show any recovery information at the start of your next flash session. Enhanced abort recovery features: ^ Reduces the amount of time for the Module ID process. ^ Lowers the risk of possible user mistakes by presenting the user the Year, Model, Engine, and Controller Type. ^ Currently only applicable to Engine and Transmission flash reprogramming. ^ The enhanced abort recovery file will only be erased upon a successful flash or manually by the user. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3092 ^ Cold booting (simultaneously pushing MORE & YES, then F4) the DRBIII(R) will not erase the enhanced abort recovery file, but cold booting the DRBIII(R) will still erase the flash file so it can be reloaded. ^ The user has a choice, at the start of a flash session, whether or not to use the enhanced abort recovery feature. If the user chooses to erase the recovery file, then the DRBIII(R) will use the original method of abort recovery. ^ Cycling the ignition key, when prompted by the DRBIII(R), is still necessary to put the controller into bootstrap (reprogramming) mode. ORIGINAL ABORT RECOVERY If the choice is made to use the original method of abort recovery, a NR module is not always able to provide the DRBIII with ID information. In this case the technician must enter this when prompted by the DRBIII(R). Be patient when performing this process. If the module does not respond to standard diagnostic requests, the DRBIII(R) may take several minutes before it determines that the engine module is in a NR state. At this point, the DRBIII(R) displays the prompt "Could not determine engine controller type. Please select from list" along with a list of possible controller types (if the DRBIII(R) is attempting to identify a TCM, the prompt will say "trans" instead of "engine" and list the possible trans controller types). Because of module variations, it is important to correctly identify the PCM/TCM type so that the correct flash procedure is used. Failure to do this will cause further problems and may damage the module. Tables are provided below to help identify the proper module type to select. These tables correctly identify the modules that were on the vehicles when they were built. However, some vehicles will have module types which were superseded to a new type when a replacement part was installed (ie: EATX4 modules replaced with an EATX4A). Correctly identify these modules using DRBIII(R) Standalone prior to attempting flash reprogramming. NOTE: When instructed to turn the key to the LOCKED position, be sure that the key is not just turned to the OFF position. The key must be rotated to the point at which it can be removed from the ignition switch. On most vehicles the switch is on the steering column and at this position the steering column is LOCKED. When instructed to turn the key to the RUN position, be careful not to turn the key past this position which may engage the starter motor. This creates electrical noise which interferes with the flash process. General Steps for Abort Recovery 1. Review all Tips and Techniques before continuing. Pay special attention to the section on Preparing to Flash a controller and to the Programmable Modules section. 2. Cycle the vehicle's ignition key to the LOCKED position and back to the RUN position. 3. Reset the DRBIII(R) by disconnecting the vehicle cable from the DRBIII(R) for 4 seconds and then reconnecting the cable. 4. Depending on where the flash session was aborted, the DRBIII(R) may require that the technician identify the control module type that was being flash reprogrammed. Use the PCM/TCM configuration table below as a guide. This step is not necessary if using the enhanced abort recovery method. 5. After selecting the proper control module type or choosing enhanced abort recovery, follow the prompts that are displayed on the DRBIII(R). NOTE: If an error message is displayed at this point, an incorrect module type was most likely selected. If this occurs, start the process over. 6. If the recovery process is unsuccessful, perform the following: a. Review the TSB/Recall notice (authorizing the flash update) and all Tips and Techniques in this document. b. Reboot/Restart the TechCONNECT Client. c. "Cold Boot" the DRBIII(R). (Press the MORE and YES buttons on the DRBIII(R) at the same time, then press F4). d. Start this process over from item # 1. If using Disconnected Mode, the flash update will have to be reloaded from the TechCONNECT Client or ISIS DVD. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3093 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3094 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3095 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3096 Programmable Modules The following pages list the various modules that have flash reprogramming capability. It does not mean that a flash is currently available. What will be described are the module types and variations, followed by items to note, and finally, abort recovery specifics if applicable. Powertrain Modules - Engine and Transmission ENGINE - POWERTRAIN CONTROL MODULE (PCM) Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3097 There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions that are somewhat unique to each type will have comments. Prior to reprogramming a PCM, retrieve the module information and module type using your DRBII I®. PCM information is used by many modules. Be sure to check DIG's before and after performing all flash reprogramming event. The DTC's associated with flash reprogramming generally relate to "lack of communication" with the other modules during the reprogramming session. SBEC Types: SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B NOTE: During recovery, if the DRBIII® is not seeing the key off, you may need to remove power (B+) to PCM by removing fuse(s) or disconnecting the PCM. When DRBIII® states to turn key ON, reconnect fuse or harness connection. Abort Recovery Specifics: ^ Follow instructions on the DRBIII® for the module type. See table above. ^ Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not correctly identify a key cycle. In this case a Modified Key Cycle routine is required. This state is present when the following message is displayed on the DRBIII(R): "Can not read Part Number. Did not see Key On or PCM/TCM Controller may not be flashable". When this occurs restart the flash session and when prompted to turn the ignition key to the LOCKED position, pull the fuse(s) that supply battery power to the module instead. When prompted to turn the key to the RUN position, replace the battery supply fuse(s) instead. JTEC Types: ^ JTEC, JTEC+ NOTE: Viper ALL - Roll down windows especially Coupes before attempting a flash. NOTE: 1999 WJ JTEC with Speed Proportional Steering module. Disconnect before and reconnect after the PCM flash reprogramming session. Also see Transmission. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. NGC Types: ^ NGC 1, NGC 2, and NGC 3 NOTE: There are derivatives of NGC 3 that will be significant when reprogramming and or testing. NGC modules use one of the longest time spans for flash reprogramming (approximately 15 minutes). The NGCI and NGC3 controllers incorporate both an engine as well as a transmission controller in a common package. The NGC2 controller incorporates the engine controller and an Electronic Throttle Control (ETC) module in place of the TCM. All NGC controllers can be visually identified by noting its four (4) wiring connectors. On manual transmission applications and the NGC2, only 3 connectors may be populated with pins. NOTE: On certain vehicles, the ABS CAB module connector MUST be disconnected prior to performing this Repair Procedure. The CAB module and the PCM are connected at the same diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is complete turn the ignition switch to the OFF position, connect the CAB module connector, and then check for DTC's. If the PCM becomes "locked" during reprogramming because the ABS CAB module connector was not disconnected, then the PCM may be recovered by following the procedure in this NOTE.

CUMMINS Types: ^ CM551 and CM84x series NOTE: Cummins flash reprogrammable PCMs are used on 1998.5 and newer Dodge Trucks. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. Model Year 2000 and earlier vehicles have one Engine Control Fuse to pull when prompted by the DRBIII(R). Model Year 2001 and later have two Engine Control Fuses (one 20 Amp and one 30 Amp) to pull when prompted by the DRBIII(R). The fuse(s) are located in the PDC and need to be pulled/removed, when prompted, for at least 10 seconds. SIEMENS Types: ^ SIM-70 NOTE: The SIM-70 is currently used on BUX PL and PG vehicles with a 1.6L ONLY. Abort Recovery Specifics: Follow DRBIII(R) prompts carefully. BOSCH Types: ^ EDC15V, EDC15-C5, and EDC16 NOTE: While there have been other Bosch modules, the EDC15V is not flash reprogrammable. Transmission controllers are usually flashed on the vehicle (since 1996). Technicians may set the pinion factor on "NEW" modules either before or after flash reprogramming. Suggestions follow. After flash reprogramming and before returning the vehicle to the customer, always perform a "QuickLearn" to the TCM. EATX Types: ^ EATX, EATX 2, EATX 3, EATX 3A, EATX 3B, EATX 4, and EATX 4A NOTE: Table shows which TCM was installed "as-built". Often TCMs are superseded by parts and or a service bulletin. Abort Recovery Specifics: ^ 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement EATX4A part numbers 56041814AD and 56028227AH currently display a P/N read failed error after the flash is completed during PIN verification. This DOES NOT mean the flash failed. Check for the part number using DRBIII(R) in standalone mode. This exists only for the service replacement modules listed above. Flash reprogramming for OE modules flash and read the part number correctly. Follow DRBIII(R) prompts carefully. NGC Types: Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3099 ^ NGC1, NGC2, NGC3 NOTE: The NGC I1and NGC 3 have the EATX/XCORE and Engine modules combined. NGC 2 does not. Vehicles with automatic transmissions using NGC2 will use an EATX4A. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. ^ 2002 DR, 2002.5 DN, 2003 AN/DN and later with NGC have shown that in some instances the CAB controller may need to be disconnected when attempting to flash the NGC controller. (This should only be performed if an error occurs at the very beginning of the TCM flash portion.) SIEMENS Types: ^ EG552 NOTE: EGS52 is used with the A580 automatic transmission WG Grand Cherokees with a 2.7L diesel engine (BUX), ZH Crossfire and VA Sprinter. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. JTEC Types: ^ JTEC,JTEC+ NOTE: Except for the 45RFE, 545RFE, and AW4 automatic transmissions, the JTEC controller also provides transmission control functions on Dodge trucks and Jeep vehicles. Additionally, they are used on some Cummins equipped Dodge trucks with manual and automatic transmissions. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. PRE 1996 EATX TRANSMISSION CONTROL MODULES Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX controller only to the PCM. Those vehicle TCMs only communicate to the DRBIII(R) using CCD communications. For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting those modules to the DRBIII(R) vehicle connector. For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because of this you will need to use the Yellow SuperCard2, CH8361,to set pinion factor or when using a "new" (superseded) TCM from parts as only the SuperCard2 properly sets the pinion factor on these updated modules. Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124. The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin 18-24-95.

MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango 1999 (TJ) Wrangler 1999 (XJ) Cherokee 1999 (WJ) Grand Cherokee SYMPTOM/CONDITION: A Powertrain Control Module (PCM) software condition exists that can cause an erroneous engine miss to occur only when in certain screens of the Diagnostic Scan Tool (DRB III). The miss will not set a Malfunction Indicator Lamp (MIL), but may be felt and can be seen while performing diagnostics with the DRB III. This condition occurs only when using the DRB III to read Diagnostic Trouble Codes (DTC's), Secondary Indicators, or 1 Trip Failures and while driving the vehicle. This is more likely to occur during hard acceleration. While in these screens, a miss may be felt by the technician, or when in the Secondary Indicators or 1 Trip Failures screen an erroneous injector circuit failure can flash on the DRB III screen with an accompany beep from the DRB III. This condition may lead technicians to incorrectly diagnose a problem and may cause erroneous repairs that will not fix the vehicle. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the DRB III with the appropriate Diagnostic Procedures Manual, verify all engine/transmission systems are functioning as designed. If DTC's are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptoms have been experienced, perform the Repair Procedure. NOTE: WHENEVER A POWERTRAIN CONTROL MODULE (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION LEVEL. USE THE FLASH PROCEDURE TO UPDATE REPLACED CONTROLLERS AS NECESSARY.

DISCUSSION: Some states that require I/M inspections are beginning to include OBD II "CARB" Readiness as a prerequisite to an I/M test. OBD Readiness tells an I/M station if the OBD II systems have run their self test. Owners, in those states that use OBD Readiness, may be denied an I/M test if one or more of the Readiness monitors read "NO" or in other words the OBD II monitors have not run their tests. It is important to understand that the MIL will not be illuminated because OBD Readiness reads "NO". MIL illumination happens when an actual malfunction or failure of a monitored emissions system occurs. It is possible to have MIL illumination for a detected failure while at the same time having a "NO" for an OBO Readiness monitor. NOTE: MIL ILLUMINATION INDICATES ADDITIONAL PROBLEMS WITH THE VEHICLE. FURTHER DIAGNOSIS AND REPAIR WILL BE REQUIRED BEFORE PROCEEDING FURTHER WITH THIS BULLETIN. OBD Readiness that reads "NO" can be caused by the following: PCM reprogramming, PCM replacement, fault code erasure, battery disconnects and/or replacement. If any of the above items occur before an I/M test, a good chance exists that one or more of the monitors will read "NO" for OBD Readiness. Some customers may be directed back to their dealers for assistance when an I/M test station has not allowed an I/M test due to Readiness status. The following procedures will help technicians efficiently run the Readiness tests so an owner can have their I/M test completed.

FAILURE CODE: XX - Service Adjustment Repair Procedure This bulletin involves operating the vehicle under specific parameters to run or complete the OBD monitors. The number of monitors applicable to a vehicle will vary by type of vehicle and emissions application. In addition, the parameters to run each monitor will vary. Preliminary Checks 1. Perform a MIL bulb check by switching the ignition key "ON" (engine off). The MIL will illuminate as a bulb check. If the MIL does not illuminate, repair the bulb or bulb circuit. 2. Connect a DRB III(R) to the vehicle. Select DRB III(R) standalone, current model year diagnostics, engine, DTC's and related functions, read DTC's. 3. Verity that no emission related DTC's are present and that the MIL is not illuminated with the engine running. NOTE: EMISSION RELATED DTC'S AND MIL ILLUMINATION MAY PREVENT OTHER OBD MONITORS FROM RUNNING. DTC'S THAT ILLUMINATE THE MIL MUST BE REPAIRED BEFORE ATTEMPTING TO RUN THE MONITORS. OBD "CARB" Readiness Check 1. With the DRB III(R) select engine, OBD II monitors, CARB Readiness Status. 2. Read the monitor status. "YES" tells you that monitor has run and is ready for an I/M test, "NO" tells you that the monitor must be run. If all monitors listed read "YES", the vehicle can be returned to the customer for completion of their I/M test. Only monitors that read "NO" must be run to read "YES". NOTE: THE MONITORS LISTED IN THE OBD "CARB" READINESS SCREEN ARE THE ONLY ONES APPLICABLE FOR THE VEHICLE BEING WORKED ON. The vehicle must be operated in various conditions (speed, temperature, etc.) for the monitors to run. Each monitor includes a pre-test and monitor test that can be viewed on the DRB III(R). The pre-test/monitor test screen lists all the preliminary parameters that must be met along with the running parameters for that specific monitor to run. An example of one screen is shown in Figure 1. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: > 25-02-98 > Oct > 98 > I/M Testing - OBDII CARB Readiness Monitor Information > Page 3136 NOTE: 1997 AND PREVIOUS MODEL VEHICLES WILL HAVE A DIFFERENT LOOKING SCREEN. PRESS THE F1 KEY TO OBTAIN MONITOR RUN CONDITIONS. THE WAY IN WHICH THE MONITORS RUN WILL BE SIMILAR. The following explains how to interpret each section of the screen: PRE-TEST REQUIREMENTS The pre-test requirements include all the operating parameters that must be met before the actual test can run. The vehicle must be operated until each item within the pre-test section are fulfilled. LOW VALUE/HIGH VALUE/BAR GRAPH The low value/high value provides the minimum and maximum operating conditions for each item (ie ECT Range must be between 170° and 260° F in Figure 1). The bar graph will begin to fill when the lowest value required for each item is met. This provides a visual indication that the parameters are being met. The vehicle should be driven until most of each pre-test bar graph is filled. MONITOR REQUIREMENTS Once all pre-test requirements are met, the vehicle must be brought within the parameters listed in the monitor requirements section for the monitors to begin running. As the monitor begins to run, the DRB III(R) will begin to beep. This is an audible indication that the test is in progress. If vehicle operation falls outside any of the parameters, the beeping will stop. If this occurs, the technician must determine if the pre-test requirements or the monitor requirements have fallen outside the window for the test and the vehicle must be driven accordingly for the test to restart. When the monitor completes its test, the DRB III(R) will beep 3 consecutive times. NOTE: THE PURGE FLOW PRE-TEST SCREEN WILL LOOK DIFFERENT THAN THE REST OF THE PRE-TEST/MONITOR SCREENS. PRESS THE F1 KEY ON THE DRB III(R) TO SEE A SIMILAR SCREEN FOR THIS MONITOR. MONITOR RUN PROCESS The following will provide the most efficient order along with tips to help run through the monitor tests quickly. The monitors listed include all possible monitors for either Front Wheel Drive or Rear Wheel Drive vehicles. The vehicle being worked on may have fewer monitors than the maximum available. Only those listed on the DRB III(R) are applicable for the vehicle being worked on. The only monitors that will require attention are those that read "NO" under the OBD "CARB" Readiness Status screen. Front Wheel Drive 1. Evaporative Leak Detection Monitor - This test will require a cold start (possibly an overnight soak either indoors or out depending on conditions). The ambient (outside) temperature must be between 4° and 32° C (40° and 90° F) with the engine coolant temperature within 6° C (10 ° F) of ambient/battery temperature. Once the above criteria are met, use the pre-test/monitor test screen on the DRB III(R) to determine the remaining requirements. 2. Catalyst Monitor - The vehicle must be driven at highway speeds for the time listed in the pre-test screen. If the vehicle is equipped with a manual transaxle, use fourth gear to help meet the requirements. 3. EGR Monitor - It is necessary to maintain TPS, MAP, and RPM ranges listed in the pre-test screen for this test to complete. 4.

Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment may lock up or become disconnected during the procedure. Flash Reprogramming is a "CRITICAL PROCESS"; an error may result in a no-start/failed control module. Most modules, encountering an interruption or failure while reprogramming, are recoverable; a recoverable module is not covered under the provisions of the warranty. This service bulletin covers items that may cause this condition, a process to restart the flash procedure, and miscellaneous information that will help prevent needless replacement of control modules. GENERAL: Flash Reprogramming is only authorized by a specific SERVICE BULLETIN, or RECALL. Review the entire Service Bulletin/Recall prior to performing a flash reprogramming update. Often other parts may need to be serviced, replaced, or tested, prior to flash reprogramming, and ARE REQUIRED as part of completing the Service Bulletin/Recall. When flashing a Powertrain Control Module (PCM) or Transmission Control Module (TCM) there are other legal requirements with labeling issues that are included in those service bulletins. Other non-emission related modules, such as instrument clusters and Body Control Modules (BCMs) do not require labels. FLASH REPROGRAMMING SEQUENCE OF EVENTS The process of flash reprogramming is similar to flashing the BIOS on a Personal Computer. Interruptions, voltage problems, and a variety of other outside interactions can potentially interfere with the process. This document seeks to provide information to minimize problems associated with vehicle control module flash reprogramming. The description that follows is for most PCMs and some TCMs. Other modules use different initiation procedures. The process starts by selecting an update from the TechCONNECT Client or ISIS and then "loading" that update into the DRBIII(R). Once the flash reprogramming update is loaded into the DRBIII(R), and before the flash reprogramming begins, the DRBIII(R) verifies that the update loaded from the TechCONNECT Client or ISIS is the proper update for the module. This is done using part number supersedence. This verification occurs only if an update is required, available (on the TechCONNECT Client or ISIS) and has been selected for programming. ^ The module is then placed into "Boot Strap" programming mode by the DRBIII(R). This module mode gives the DRBIII(R) permission and the ability to proceed with the flash reprogramming session. ^ Next, the current part number, which resides in the module's flash memory, is stored in a "Safe Memory" location within the module. This memory location is not affected by flash memory erasure and reprogramming, which are to follow. ^ Once the part number is safely stored, the flash memory in the control module is erased. From this point forward any interruption in the flash process, Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3144 will result in a Non-Responsive module (NR). A NR module is a module that is either partially erased or partially programmed. ^ After erasure, the actual reprogramming procedure starts, and the update software is programmed into the flash memory within the module. ^ When reprogramming is completed, the flash memory is verified through an internal process in the DRBIII(R) using a "Check Sum". This value is compared against another value that represents what should be in memory and when matched, verifies successful reprogramming. ^ Next, a DRBIII(R) prompt is displayed instructing that the ignition switch be turned OFF. The module exits the "Boot Strap" mode when the switch is turned off. ^ After a slight pause, the DRBIII(R) will prompt for the ignition switch to be turned ON. The DRBIII(R) then reads the new part number in flash memory (along with a new computer program the new part number is placed into the module's memory). If the new part number matches the expected part number, the flash reprogramming session has completed successfully. SOFTWARE VERSIONS MUST BE CURRENT Before attempting a flash reprogramming session using the TechCONNECT Client, make sure you have the most current DRBIII(R) software installed. To verify whether your DRBIII(R) software is current, check the upper right-hand corner of the TechCONNECT Client screen for DRBIII(R) Available Version, DRBIII(R) Current Version. Often, because of multiple DRBIII(R)s in the shop, not all will get updated on a timely manner. The installed DRBIII(R) software version can generally be found at the bottom center of most screens. Alternately the version can be checked by pressing 6, 2, 5 from the DRBIII(R) Main Menu and comparing it to what is available from a current TechCONNECT Client as described above. If the TechCONNECT Client is current and the DRBIII(R) is not, it may be due to the fact that the TechCONNECT Client does not force DRBIII(R) updates for "minor" revisions. Changes and new support are added to the Vehicle Flash application on "minor" revisions on a regular basis. This is why your TechCONNECT Client and DRBIII(R) must have the LATEST software revisions installed. DO NOT PASS on the option for updating to a "minor" revision! Major updates require the DRBIII(R) to be updated prior to allowing any flash programming. DRBIII(R) CABLES A NEW DRBIII(R) cable was released as an Essential Service Tool! CH7000A - 8 ft. Cable, DRBIII(R) to OBDII (J1962) DLC Connector. CH7000A is the required cable for ALL flash reprogramming. The older CH7000 cable can be used for diagnostics ONLY. One (1) cable was shipped to all dealerships. Easily identified, the correct cable has a RED connector, which plugs into the DRBIII(R). The cable modification enhances the DRBIII(R) communication capabilities when dealing with the flash requirements of certain controllers/ECUs affected in part by the recent changes in DLC connector configurations. The new cable is required for ALL flash reprogramming sessions, and can be used wherever the previous CH700017001 cables were used. While not recommended for flash reprogramming usage, if you require a longer cable, there is also a 12-foot cable released under pin CH7001A The production of the previous CH700017001 cables has ceased. All orders placed will be superseded to part number CH7000A/CH7001A. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3145 NOTE: Consider all cables wear items. Always inspect for worn, damaged cables, connectors that are damaged or do not lock securely, and all mating connections including checking for corrosion on the pins. REPLACE ALL suspect cables. Do not use worn or damaged cables when flash reprogramming. Failure to use the new cable or to use a damaged cable often results in failed flash reprogramming sessions. The 2 door Sebring, Stratus, and Avenger coupes (supplied by MMC) generally use the CH7O1O cable (Pre-OBDII MMC vehicles will use the CH7005 cable). TechCONNECT CABLE (GPIB) Replace any suspect GPIB cable. The GPIB cable provides the connection between TechCONNECT Client and the DRBIII(R). This cable is used by the TechCONNECT Client for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes disconnected during a flash session, you may have to reload the update file that you selected on the TechCONNECT Client. TROUBLESHOOTING CONNECTIVITY OF THE DRBIII(R) UNIT TO THE TechCONNECT APPLICATION. 1. Turn-on the power to the DRBIII(R) unit. 2. Select option 2 "Connect to TechCONNECT" and press Enter. 3. Attach the male mini D-shell amphenol GPIB connector of the new DRBIII(R) cable (part number CH7035B) to the DRBIII(R) unit. 4. Insure that the larger female D-shell amphenol GPIB connector of the new DRBIII(R) cable is properly attached to the male D-shell amphenol GPIB connector on the GPIB-USB-B protocol converter, (part number CHGPIB-B). 5. Attach the USB cable from the GPIB-USB-B protocol converter to one of the USB ports on the rear panel of the client CPU. 6. When the cable is attached to the USB port of the CPU for the first time, Windows 2000 will detect the device and install software for it. Please wait for 25-30 seconds to complete the installation. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3146 ISIS NULL MODEM CABLE Replace any suspect null modem cables. International (ISIS), a PC-based CD program similar to TechCONNECT Client uses a null modem cable for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes disconnected during a flash download session, you will have to reload the update file or files. GENERAL NOTES FOR CABLES AND VEHICLE CONNECTIONS Consider ALL cables to be wear items. Many successful dealers have dedicated cables devoted to "Flash ONLY". Always have spare CH7000A, CH7010 and CH2002 GPIB or null modem cables available. Inspect vehicle diagnostic connectors for potential problems that might cause communication interruptions. There are now clip repair kits available through teamPSE to replace the retaining clips for two of these cables. To protect the DRBIII(R) from internal damage, the clips are designed to fail at above 25 lbs. of axial force. Kits are described in the table. It is a good practice to discard cables that have damage to the pins, cuts, corrosion, or general damage beyond the retaining clips.

The CH8432 Supplemental Reprogramming Tool (SRT) was shipped as a 2001 Essential Tool. The flash reprogramming update files will be downloaded from TechCONNECT Client to the SRT for flash reprogramming sessions on these vehicles. Users should closely follow the instructions that come with the tool. If the tool has not been initialized, there is a known condition where it may take up to 5 or more attempts for it to fully initialize and become functional. NOTE: Once it has successfully flashed, it is initialized and no further action is required. PREPARING TO FLASH It is highly recommended that a sign, or other process, be used that notifies other users that a FLASH SESSION IS IN-PROGRESS and must NOT be interrupted. Interrupting some flash reprogramming sessions at critical junctures can render a module inoperative. Another user may not realize that a flash session is in-progress and may disturb or disconnect the DRBIII(R) or do something on the vehicle that could interrupt the flash process. Before starting the flash session, read, record and erase all DTCs found on the vehicle. Also "Cold Boot" the DRBIII(R) and download the flash since this will erase the flash file from the DRBIII(R) memory. (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press "F4"). Be sure to arrange the TechCONNECT and DRBIII(R) so that no cables are stretched across an area where someone might trip over or kick a cable. When setting up your DRBIII(R), insure that it rests on a surface where it will not fall or be bumped during reprogramming e.g.: DRBIII's have been known to be swept off vehicle windshields by accident when a user bumps the wiper switch). Check User settings on the DRBIII(R). From the DRBIII(R) Main menu, press 6,1 and check to make sure item 1. Echo on PC is set to OFF. On occasion, when Echo on PC is set to ON, flash reprogramming errors may occur. VEHICLE BATTERY VOLTAGE The flash programming procedure puts a load on the electrical system that may last from five to twenty minutes depending on the particular flash reprogramming update. Connect a battery charger to the vehicle. Set the charger to as close to 14 volts as possible. If the charger has a timer, set it for 30 minutes BEFORE starting a flash reprogramming session. This will help to prevent unwanted resets by either the DRBIII(R) and/or the vehicle module that are caused by voltage fluctuations. Alternately, as a bare minimum, use a "Battery Jump Box" when a battery charger is unavailable to ensure adequate and stable system voltages on the module being flash reprogrammed. POLICY: Information Only Disclaimer: This bulletin is supplied as technical information only and is not an authorization for repair. Connected/Disconnected Flash Mode Using TechCONNECT CONNECTED MODE FLASHING USING TechCONNECT NOTE: Capable but not recommended. In this mode, the DRBIII(R) remains connected to the TechCONNECT Client and the vehicle throughout the flash session. The DRBIII(R) is connected to the TechCONNECT Client using the GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the CH7000A for most vehicles). This mode is useful when the TechCONNECT Client is next to the vehicle being flashed. Another advantage of this mode is that you are able to determine all available flash updates for the vehicle you are connected to by clicking on the "Read Part Number(s) From Vehicle" button. Again, it is important that other users do not attempt to reboot or move the TechCONNECT Client while a flash update is in-progress. The reprogramming procedure of this mode is initiated by selecting the controller option and clicking "Download/Update" button on the TechCONNECT client. DISCONNECTED FLASH MODE NOTE: Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3148 This is the preferred method. This mode allows a user to flash a vehicle without being connected to the TechCONNECT Client. This is a popular mode for flashing in a remote area of the service garage or in a back lot. Before you attempt to use this mode, you must configure the DRBIII(R) for the desired update(s). To do this, you must connect the DRBIII(R) to the TechCONNECT Client using the GPIB cable and the CH7025 cable. It is not necessary to be connected to a vehicle. The GPIB (CH7035) cable will be used to communicate with the TechCONNECT Client (for update file downloading) while the CH7025 cable is used to provide power to the DRBIII(R). After making the above connections, you are able to select one or more updates that you want to perform. These selections are made by highlighting the desired updates and then clicking on the "Download/Update" button by selecting the DRBIII(R) option on the TechCONNECT client. Obviously, the DRBIII(R) does not have unlimited memory. If the file size of the selected updates exceeds 948 KB, the "DRB Space Used" indicator (at the bottom-center of the TechCONNECT Client screen) will change color from GREEN to RED. At this point you must de-select entries until the indicator changes color to GREEN again. When the updates have finished downloading, you may disconnect from the TechCONNECT Client and take the DRBIII(R) to wherever the vehicle is located. The updates will remain in DRBIII(R) memory for 8 hours while the DRBIII(R) is without power. If the DRBIII(R) is powered up for several minutes before the 8 hour time period has expired, the update files will remain on the DRBIII(R) for another 8 hours without power. To start the actual flash process, after connecting to the vehicle in Disconnected Mode, you must press "7 - Vehicle Flash" from the Main Menu on the DRBIII(R). Step by step instruction will follow on the DRBIII(R) display. As with Connected Flash Mode, take the necessary precautions to insure that others are aware of the flash session and that nothing disturbs the vehicle, DRBIII(R), or cabling while performing the flash. Remember to use a battery charger set to 14 volts or a "battery jump box". Pay Attention While Performing Flash Reprogram Procedures PAY ATTENTION WHILE PERFORMING FLASH REPROGRAMMING PROCEDURES Before downloading the flash files, double check to see if the files that you have selected are the appropriate ones for that vehicle. Don't forget about the "Read Part Numbers From Vehicle" option on TechCONNECT Client, this can be of great assistance when trying to flash a module. If the files selected don't download on the first attempt, try again. The technician should NOT leave the vehicle when flash reprogramming a module. Again, check to make sure that all cable connections are secure and that the DRBIII(R) rests on a stable surface. If you are using a battery charger, insure that the settings and charging times are correct and that the battery post clamps are securely fastened. Read, record, and erase all DTCs found on the vehicle. Read and record the module type and part number from the module that is to be flash reprogrammed. Some control modules are not "abort-recovery" capable. When this is true, the scan tool will indicate so by displaying a WARNING message prior to the start of reprogramming. For these modules it is especially important that all precautions and procedures, outlined here, are carefully followed. Pay special attention to DRBIII(R) screen directions relating to key cycles. Missing a "Key ON" or "Key OFF" can cause the module to have to be reflashed again. Due to the variety of module types and vehicle options, you can't always anticipate key prompts, so be alert and ready to respond to DRBIII(R) instructions. Some screens will also instruct that certain modules, connectors or fuses be disconnected or pulled prior to the start of reprogramming and re-installed immediately after completion. Be careful not to anticipate the steps or order of operations for reprogramming any vehicle modules. Because of the many possible changes that occur with each new release of scan tool software, always allow the TSB/Recall and scan tool instructions to be your guide while performing flash reprogramming. Flash reprogramming sessions usually range from 5 to 20 minutes. If the flash session has not completed within 25 minutes after starting a flash reprogramming update, an error has most likely occurred (Record the message that appears on the screen when a failure occurs). If this is the case, or if you know that the flash process was interrupted, cycle the ignition key (OFF to the locked position, then back ON). Reset the DRBIII(R) (power down for 4 seconds and then power up) before attempting to restart the flash process. If the module still won't respond, turn the ignition key off, disconnect the module from the vehicle for 2 minutes, reconnect the module, turn the ignition key to run and try to restart the flash process again. Regardless of what mode that you are in (Connected Flash or Disconnected Flash), if you have tried twice (2 times) unsuccessfully to do a flash recovery and ALL DRBIII(R) instructions were followed, perform the following: ^ Cold boot the DRBIII(R). This resets memory and removes all update files from the DRBIII(R). (Push MORE and YES buttons at the same time, then press F4). ^ Reload the flash update file from the TechCONNECT Client. ^ If it fails to complete in the connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to the DRBIII(R). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3149 ^ Proceed to reflash the module. On vehicles that have multiple flash updates available, always complete and verify each flash update before attempting the next one. After all flash reprogramming is completed, read and erase all DTCs in all modules on the vehicle. A variety of DTCs may be set, which are usually related to a loss of communication with the module(s) being reprogrammed. Verify the update by reading the new part number using the DRBIII(R). A good double check is to read the part number using DRBIII(R) stand alone. At times, other modules, wired in parallel, to the DLC connector have prevented flash reprogramming sessions to be successful. After the failed attempt, review the appropriate wiring diagram for the vehicle you are flash reprogramming and, with the key "OFF"; disconnect the other modules and retry the flash. Complete the flash, turn the key "OFF" and reconnect any modules that were disconnected. Refer to the "Programmable Modules" section later in this document for more information. Error Messages ERROR MESSAGES Block Echo/Compare Errors Block Echo and Block Compare errors are often caused by voltage fluctuations, faulty I/O cables (CH7OOOA, CH7005, CH7010) or faulty communication connections at the diagnostic connector. Inspect for these conditions and review the sections on Vehicle Battery Voltage and Cable recommendations. Checksum Errors Checksum Errors are generally caused by corrupt flash update files, which can be caused by DRBIII(R) memory problems. If the DRBIII(R) has been without power for more than 8 hours, the update files and system memory could be in a corrupted state. "Cold Boot" the DRBIII(R). (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press "F4"). Reload the flash update file(s) from the TechCONNECT CLIENT. If it fails to complete in the connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to the DRBIII(R). Then re-attempt the flash reprogramming process. Enhanced and Original Abort Recovery ENHANCED ABORT RECOVERY Interruptions in the flash process are one of the main reasons for failed flash sessions and non-responsive (NR) modules. Interrupting the flash process after the erase phase has started will leave the control module in a non-functional state. Generally, but not always, NR modules may be recovered successfully. Briefly, abort recovery is the process used to get a NR module back to a fully functional state with the latest software update. The technician should be familiar with the other sections in this document and follow all DRBIII(R) user prompts carefully. There are two methods for abort-recovery. The newer method is called "Enhanced Abort Recovery". This is the preferred method since the original method takes several minutes longer and requires the correct selection of module type from a list of possible PCM's or TCM's. Starting with Release 60.1, a new useful feature was added to the flash reprogramming application for Engine and Transmission control modules. The DRBIII(R) "writes" the YME and Controller Type information to a "Safe Memory" location. This method allows for rapid recovery of the module part number and minimizes errors that could otherwise be made by selecting the wrong controller type. It also assumes that the user will attempt abort recovery for a failed flash attempt before moving to another vehicle with the same DRBIII(R). If you need to move to another vehicle for flash reprogramming you must erase the saved recovery information in order to successfully perform flash reprogramming. Be careful to match the YME information displayed on the enhanced abort recovery screen with the vehicle and module that you are attempting to recover. If you use the recovery file on a different vehicle and module you could damage the module. The recovery information will be displayed on your DRBIII(R), at the start of a flash session, only if you previously encountered a problem that prevented a flash session from completing normally. If your prior flash session was successful, the DRBIII(R) automatically erases the recovery file so that the flash application will not show any recovery information at the start of your next flash session. Enhanced abort recovery features: ^ Reduces the amount of time for the Module ID process. ^ Lowers the risk of possible user mistakes by presenting the user the Year, Model, Engine, and Controller Type. ^ Currently only applicable to Engine and Transmission flash reprogramming. ^ The enhanced abort recovery file will only be erased upon a successful flash or manually by the user. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3150 ^ Cold booting (simultaneously pushing MORE & YES, then F4) the DRBIII(R) will not erase the enhanced abort recovery file, but cold booting the DRBIII(R) will still erase the flash file so it can be reloaded. ^ The user has a choice, at the start of a flash session, whether or not to use the enhanced abort recovery feature. If the user chooses to erase the recovery file, then the DRBIII(R) will use the original method of abort recovery. ^ Cycling the ignition key, when prompted by the DRBIII(R), is still necessary to put the controller into bootstrap (reprogramming) mode. ORIGINAL ABORT RECOVERY If the choice is made to use the original method of abort recovery, a NR module is not always able to provide the DRBIII with ID information. In this case the technician must enter this when prompted by the DRBIII(R). Be patient when performing this process. If the module does not respond to standard diagnostic requests, the DRBIII(R) may take several minutes before it determines that the engine module is in a NR state. At this point, the DRBIII(R) displays the prompt "Could not determine engine controller type. Please select from list" along with a list of possible controller types (if the DRBIII(R) is attempting to identify a TCM, the prompt will say "trans" instead of "engine" and list the possible trans controller types). Because of module variations, it is important to correctly identify the PCM/TCM type so that the correct flash procedure is used. Failure to do this will cause further problems and may damage the module. Tables are provided below to help identify the proper module type to select. These tables correctly identify the modules that were on the vehicles when they were built. However, some vehicles will have module types which were superseded to a new type when a replacement part was installed (ie: EATX4 modules replaced with an EATX4A). Correctly identify these modules using DRBIII(R) Standalone prior to attempting flash reprogramming. NOTE: When instructed to turn the key to the LOCKED position, be sure that the key is not just turned to the OFF position. The key must be rotated to the point at which it can be removed from the ignition switch. On most vehicles the switch is on the steering column and at this position the steering column is LOCKED. When instructed to turn the key to the RUN position, be careful not to turn the key past this position which may engage the starter motor. This creates electrical noise which interferes with the flash process. General Steps for Abort Recovery 1. Review all Tips and Techniques before continuing. Pay special attention to the section on Preparing to Flash a controller and to the Programmable Modules section. 2. Cycle the vehicle's ignition key to the LOCKED position and back to the RUN position. 3. Reset the DRBIII(R) by disconnecting the vehicle cable from the DRBIII(R) for 4 seconds and then reconnecting the cable. 4. Depending on where the flash session was aborted, the DRBIII(R) may require that the technician identify the control module type that was being flash reprogrammed. Use the PCM/TCM configuration table below as a guide. This step is not necessary if using the enhanced abort recovery method. 5. After selecting the proper control module type or choosing enhanced abort recovery, follow the prompts that are displayed on the DRBIII(R). NOTE: If an error message is displayed at this point, an incorrect module type was most likely selected. If this occurs, start the process over. 6. If the recovery process is unsuccessful, perform the following: a. Review the TSB/Recall notice (authorizing the flash update) and all Tips and Techniques in this document. b. Reboot/Restart the TechCONNECT Client. c. "Cold Boot" the DRBIII(R). (Press the MORE and YES buttons on the DRBIII(R) at the same time, then press F4). d. Start this process over from item # 1. If using Disconnected Mode, the flash update will have to be reloaded from the TechCONNECT Client or ISIS DVD. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3151 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3152 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3153 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3154 Programmable Modules The following pages list the various modules that have flash reprogramming capability. It does not mean that a flash is currently available. What will be described are the module types and variations, followed by items to note, and finally, abort recovery specifics if applicable. Powertrain Modules - Engine and Transmission ENGINE - POWERTRAIN CONTROL MODULE (PCM) Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3155 There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions that are somewhat unique to each type will have comments. Prior to reprogramming a PCM, retrieve the module information and module type using your DRBII I®. PCM information is used by many modules. Be sure to check DIG's before and after performing all flash reprogramming event. The DTC's associated with flash reprogramming generally relate to "lack of communication" with the other modules during the reprogramming session. SBEC Types: SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B NOTE: During recovery, if the DRBIII® is not seeing the key off, you may need to remove power (B+) to PCM by removing fuse(s) or disconnecting the PCM. When DRBIII® states to turn key ON, reconnect fuse or harness connection. Abort Recovery Specifics: ^ Follow instructions on the DRBIII® for the module type. See table above. ^ Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not correctly identify a key cycle. In this case a Modified Key Cycle routine is required. This state is present when the following message is displayed on the DRBIII(R): "Can not read Part Number. Did not see Key On or PCM/TCM Controller may not be flashable". When this occurs restart the flash session and when prompted to turn the ignition key to the LOCKED position, pull the fuse(s) that supply battery power to the module instead. When prompted to turn the key to the RUN position, replace the battery supply fuse(s) instead. JTEC Types: ^ JTEC, JTEC+ NOTE: Viper ALL - Roll down windows especially Coupes before attempting a flash. NOTE: 1999 WJ JTEC with Speed Proportional Steering module. Disconnect before and reconnect after the PCM flash reprogramming session. Also see Transmission. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. NGC Types: ^ NGC 1, NGC 2, and NGC 3 NOTE: There are derivatives of NGC 3 that will be significant when reprogramming and or testing. NGC modules use one of the longest time spans for flash reprogramming (approximately 15 minutes). The NGCI and NGC3 controllers incorporate both an engine as well as a transmission controller in a common package. The NGC2 controller incorporates the engine controller and an Electronic Throttle Control (ETC) module in place of the TCM. All NGC controllers can be visually identified by noting its four (4) wiring connectors. On manual transmission applications and the NGC2, only 3 connectors may be populated with pins. NOTE: On certain vehicles, the ABS CAB module connector MUST be disconnected prior to performing this Repair Procedure. The CAB module and the PCM are connected at the same diagnostic connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB module connector, and reprogram the PCM per the Repair Procedure. When reprogramming is complete turn the ignition switch to the OFF position, connect the CAB module connector, and then check for DTC's. If the PCM becomes "locked" during reprogramming because the ABS CAB module connector was not disconnected, then the PCM may be recovered by following the procedure in this NOTE.

CUMMINS Types: ^ CM551 and CM84x series NOTE: Cummins flash reprogrammable PCMs are used on 1998.5 and newer Dodge Trucks. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. Model Year 2000 and earlier vehicles have one Engine Control Fuse to pull when prompted by the DRBIII(R). Model Year 2001 and later have two Engine Control Fuses (one 20 Amp and one 30 Amp) to pull when prompted by the DRBIII(R). The fuse(s) are located in the PDC and need to be pulled/removed, when prompted, for at least 10 seconds. SIEMENS Types: ^ SIM-70 NOTE: The SIM-70 is currently used on BUX PL and PG vehicles with a 1.6L ONLY. Abort Recovery Specifics: Follow DRBIII(R) prompts carefully. BOSCH Types: ^ EDC15V, EDC15-C5, and EDC16 NOTE: While there have been other Bosch modules, the EDC15V is not flash reprogrammable. Transmission controllers are usually flashed on the vehicle (since 1996). Technicians may set the pinion factor on "NEW" modules either before or after flash reprogramming. Suggestions follow. After flash reprogramming and before returning the vehicle to the customer, always perform a "QuickLearn" to the TCM. EATX Types: ^ EATX, EATX 2, EATX 3, EATX 3A, EATX 3B, EATX 4, and EATX 4A NOTE: Table shows which TCM was installed "as-built". Often TCMs are superseded by parts and or a service bulletin. Abort Recovery Specifics: ^ 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement EATX4A part numbers 56041814AD and 56028227AH currently display a P/N read failed error after the flash is completed during PIN verification. This DOES NOT mean the flash failed. Check for the part number using DRBIII(R) in standalone mode. This exists only for the service replacement modules listed above. Flash reprogramming for OE modules flash and read the part number correctly. Follow DRBIII(R) prompts carefully. NGC Types: Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: > 18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3157 ^ NGC1, NGC2, NGC3 NOTE: The NGC I1and NGC 3 have the EATX/XCORE and Engine modules combined. NGC 2 does not. Vehicles with automatic transmissions using NGC2 will use an EATX4A. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. ^ 2002 DR, 2002.5 DN, 2003 AN/DN and later with NGC have shown that in some instances the CAB controller may need to be disconnected when attempting to flash the NGC controller. (This should only be performed if an error occurs at the very beginning of the TCM flash portion.) SIEMENS Types: ^ EG552 NOTE: EGS52 is used with the A580 automatic transmission WG Grand Cherokees with a 2.7L diesel engine (BUX), ZH Crossfire and VA Sprinter. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. JTEC Types: ^ JTEC,JTEC+ NOTE: Except for the 45RFE, 545RFE, and AW4 automatic transmissions, the JTEC controller also provides transmission control functions on Dodge trucks and Jeep vehicles. Additionally, they are used on some Cummins equipped Dodge trucks with manual and automatic transmissions. Abort Recovery Specifics: ^ Follow DRBIII(R) prompts carefully. PRE 1996 EATX TRANSMISSION CONTROL MODULES Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX controller only to the PCM. Those vehicle TCMs only communicate to the DRBIII(R) using CCD communications. For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting those modules to the DRBIII(R) vehicle connector. For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because of this you will need to use the Yellow SuperCard2, CH8361,to set pinion factor or when using a "new" (superseded) TCM from parts as only the SuperCard2 properly sets the pinion factor on these updated modules. Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124. The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin 18-24-95.

SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

OVERVIEW: This bulletin involves replacing the transmission regulator valve. MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5.

Repeat Step 14 noting whether or not the vibration increased or decreased. 30. After evaluating all four indexed positions, phase the propeller shaft to the position that produced the lowest vibration amplitude. The vibration can be fine tuned by rotating the propshaft clockwise or counterclockwise one spline at a time. 31. Once the optimum position between the transmission and propeller shaft has been determined, the propeller shaft must now be indexed to the rear axle pinion yoke. Remove the bolts holding the universal clamps to the pinion yoke and rotate the propshaft 1800 from the scribed mark made in Step 13. NOTE: DO NOT SEPARATE THE PROPSHAFT FROM THE TRANSMISSION OUTPUT SHAFT. 32. Position the universal joint into the axle yoke. Install the universal joint strap and bolts. Tighten the bolts to 19 N.m (14 ft. lbs.). 33. Repeat Step 14 again noting whether or not the vibration increased or decreased. 34.

FAILURE CODE: P8 - New Part Repair Procedure 1. Raise and support the vehicle on safety stands. 2. Shift the transmission to the NEUTRAL position. 3. ** Vehicles built on or after October 3, 1998 (MDH 1003XX) have the new aluminum graphite rear propeller shaft. These vehicles may require indexing only, unless a failure of the transmission extension housing seal is observed. If the transmission extension housing seal requires replacement, then proceed with step 4. If the extension housing seal is good, then proceed with step 10. ** 4. Remove the bolts holding the universal joint clamps to the pinion yoke. 5. Slide the slip yoke off of the transmission output shaft and remove the propeller shaft. 6. Remove the transmission extension housing yoke seal. 7. Inspect the extension housing bushing. If the bushing has slid rearward, proceed to the next step. If the bushing is in its original position, proceed to Step 9. 8. Replace the transmission extension housing with p/n 05003231AA. Follow the procedures identified in the 1999 Dakota Service Manual (Publication No. 81-370-9110), pages 21-304 through 21-318 to transfer the components from the old transmission extension housing to the new one. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Case, A/T > Component Information > Technical Service Bulletins > All Technical Service Bulletins for Case: > 03-02-99A > Aug > 99 > Driveline High Speed Vibration > Page 3241 9. Install new transmission extension housing seal p/n 04531216 into the extension housing using Special Tool C-3995-A (seal installer) (Figure 1). NOTE: THE NEXT STEPS OF THE PROCEDURE WILL ALLOW FOR INDEXING OF THE NEW PROPELLER SHAFT. 10. Using a paint pen or equivalent, place tour marks, equally spaced (00, 900, 1800, and 2700 positions) on the vibration dampener of the new propeller shaft p/n 52105950AA. Then, number the marks 1 through 4 in order. 11. With the number "1" identification mark facing straight down, slide the slip yoke of the new propeller shaft onto the transmission output shaft. 12. Position the universal joint into the axle yoke. Install the universal joint strap and bolts. Tighten the bolts to 19 N.m (14 ft. lbs.). 13. Using a paint pen or equivalent, place a line across the axle pinion yoke and the propeller shaft yoke for installation reference later in the procedure (Figure 2). 14. Start the engine, place the transmission gear selector into DRIVE, and then SLOWLY accelerate until maximum driveline vibration has been identified. Note the vehicle speed at which the vibration occurs and the amplitude of the vibration. NOTE: IT IS RECOMMENDED THAT SPECIAL TOOL 0T38793 (ELECTRONIC VIBRATION ANALYZER) BE USED TO HELP IDENTIFY THE AMPLITUDE OF DRIVELINE VIBRATIONS 15. Remove the bolts holding the universal joint clamps to the pinion yoke. 16. Rotate the propeller shaft until the number "1" is facing straight down. 17. Carefully slide the propeller shaft off of the transmission output shaft. Rotate the propeller shaft 900 until the number "2" is facing straight down. Then, slide the slip yoke of the propeller shaft onto the transmission output shaft. 18. Position the universal joint into the axle yoke. Install the universal joint strap and bolts. Tighten the bolts to 19 N.m (14 ft. lbs.). NOTE: MAINTAIN THE SAME AXLE PINION YOKE AND PROPELLER SHAFT YOKE ORIENTATION BY ALIGNING THE SCRIBED REFERENCE MARKS CREATED IN STEP 13. 19.

Carefully slide the propeller shaft off of the transmission output shaft. Rotate the propeller shaft 900 until the number "3" is facing straight down. Then, slide the slip yoke of the propeller shaft onto the transmission output shaft. 23. Position the universal joint into the axle yoke. Install the universal joint strap and bolts. Tighten the bolts to 19 N.m (14 ft. lbs.). NOTE: MAINTAIN THE SAME AXLE PINION YOKE AND PROPELLER SHAFT YOKE ORIENTATION BY ALIGNING THE SCRIBED REFERENCE MARKS CREATED IN STEP 13. 24. Repeat Step 14 noting whether or not the vibration increased or decreased. 25. Remove the bolts holding the universal joint clamps to the pinion yoke. 26. Rotate the propeller shaft until the number "3" is facing straight down. 27. Carefully slide the propeller shaft off of the transmission output shaft. Rotate the propeller shaft 90° until the number "4' is facing straight down. Then, slide the slip yoke of the propeller shaft onto the transmission output shaft. 28. Position the universal joint into the axle yoke. Install the universal joint strap and bolts. Tighten the bolts to 19 N.m (14 ft. lbs.). NOTE: MAINTAIN THE SAME AXLE PINION YOKE AND PROPELLER SHAFT YOKE ORIENTATION BY ALIGNING THE SCRIBED REFERENCE MARKS CREATED IN STEP 13. 29. Repeat Step 14 noting whether or not the vibration increased or decreased. 30. After evaluating all four indexed positions, phase the propeller shaft to the position that produced the lowest vibration amplitude. The vibration can be fine tuned by rotating the propshaft clockwise or counterclockwise one spline at a time. 31. Once the optimum position between the transmission and propeller shaft has been determined, the propeller shaft must now be indexed to the rear axle pinion yoke. Remove the bolts holding the universal clamps to the pinion yoke and rotate the propshaft 1800 from the scribed mark made in Step 13. NOTE: DO NOT SEPARATE THE PROPSHAFT FROM THE TRANSMISSION OUTPUT SHAFT. 32. Position the universal joint into the axle yoke. Install the universal joint strap and bolts. Tighten the bolts to 19 N.m (14 ft. lbs.). 33. Repeat Step 14 again noting whether or not the vibration increased or decreased. 34. If the peak vibration amplitudes decrease, the propshaft is indexed. If the peak vibration amplitudes increase, return the axle end of the propshaft to its original position. 35. Install the tire/wheel assemblies. 36. Remove the safety stands and lower the vehicle. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Clutch, A/T > Component Information > Specifications > Mechanical Specifications Clutch: Mechanical Specifications Direct clutch disc usage 8 discs ct Clutch pack clearance/ Front 3-disc.0.070-0.129\ Clutch pack clearance/ Front 3-disc.0.070-0.129\ Clutch pack clearance/ Front 3-disc. 0.070-0.129 in Front clutch spring usage 9 springs Thrust Washer Dimensions THICKNESS SPECIFICATION Front clutch thrust washer (reaction shaft support hub) .............................................................................................................................................................. ....................................................... 0.061 inch .................................................................................... ................................................................................................................................. 0.084 inch .......... .............................................................................................................................................................. ............................................. 0.102 inch One-Way Clutch TIGHTENING SPECIFICATIONS Bolt, overrunning clutch cam ............................................................................................................... ............................................................... 13 ft. lbs.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure. NOTE: WHENEVER A POWERTRAIN (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE REPLACEMENT CONTROLLER MUST BE VERIFIED FOR THE LATEST REVISION LEVEL.

DISCUSSION: ATF+4(R) - (Type 9602) is being used as factory fill for Chrysler Group automatic transmissions. ATF+4(R) is recommended for all vehicles equipped with Chrysler Group automatic transmissions EXCEPT FOR THOSE LISTED IN THE NOTE ABOVE. NOTE: ATF+4(R) must always be used in vehicles that were originally filled with ATF+4(R). DO NOT USE ANY OTHER FLUID. NOTE: ATF+4(R) is backward compatible with ATF+3, ATF+2, and ATF+. Additionally, ATF+4(R) can be used to top off vehicles that used ATF+3, ATF+2, or ATF+. NOTE: If ATF+4® is used to service models originally filled with ATF+3, ATF+2, and ATF+ the fluid maintenance schedules listed for that model does not change. The service interval currently in effect for a given model should continue to be followed. Refer to the Service or Owners manual for maintenance schedule directions. In general terms, If ATF+, ATF+2 or ATF+3 was the recommended fluid, it is now recommended to use ATF+4® BENEFITS ^ Better anti-wear properties ^ Improved rust/corrosion prevention ^ Controls oxidation ^ Eliminates deposits ^ Controls friction ^ Retains anti-foaming properties ^ Superior properties for low temperature operation FLUID COLOR Mopar ATF+4(R) has exceptional durability. However, the red dye used in ATF+4(R) is not permanent; as the fluid ages it may become darker or appear brown in color. ATF+4(R) also has a unique odor that may change with age. With ATF+4(R) fluid, color and odor are no longer indicators of fluid condition and do not necessarily support a fluid change.

DISCUSSION: Some newly delivered vehicles may exhibit what looks to be a transmission front pump seal leak due to wetness around the lower edge of the bell housing. The wetness could be caused by the assembly plant initially overfilling transmissions and correcting the overfull condition before the vehicles leave the plant. The wetness, in this case, is due to fluid seeping out of the transmission vent hole while it was overfull.

The volume should be checked using the following procedure: 1. Disconnect the From cooler line at the transmission and place a collecting container under the disconnected line. CAUTION: With the fluid set at the proper level, fluid collection should not exceed 1 quart or internal damage to the transmission may occur. 2. Run the engine at curb idle speed, with the shift selector in neutral. 3. If fluid flow is intermittent or it takes more than 20 seconds to collect one quart of ATF+4, disconnect the To Cooler line at the transaxle. 4. Refill the transaxle to proper level and recheck pump volume. 5. If flow is found to be within acceptable limits, replace the cooler. Then fill transmission to the proper level, using MOPAR ATF+4 (Type 9602) automatic transmission fluid. 6. If fluid flow is still found to be inadequate, check the line pressure using the Transaxle Hydraulic Pressure Test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Specifications Governor: Specifications PRESSURE SPECIFICATIONS D Range (Closed Throttle) At Idle In D, 1 or 2 ................................................................................................................................ .......................................................... 0-1.5 psi NOTE: - Pressure should respond smoothly to changes in mph and return to 0-1.5 psi. - Pressure at stand still above 1.5 psi will prevent transmission from downshifting. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Specifications > Page 3291 Governor: Locations Governor Pressure Sensor, Transmission Temperature Sensor, Governor Pressure Solenoid, Governor The governor pressure sender and the transmission fluid temperature thermistor are separate sensors in the same component.

Components used for governor pressure control include: Governor body - Valve body transfer plate - Governor pressure solenoid valve - Governor pressure sensor - Fluid temperature thermistor - Throttle position sensor (TPS) - Transmission speed sensor - Powertrain control module (PCM) Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Description and Operation > Electronic Governor > Page 3295 Governor: Description and Operation Governor Pressure Solenoid Valve Fig. 3 The solenoid valve is a duty-cycle solenoid which regulates the governor pressure needed for upshifts and downshifts. It is an electro-hydraulic device located in the governor body on the valve body transfer plate (Fig. 3). The inlet side of the solenoid valve is exposed to normal transmission line pressure. The outlet side of the valve leads to the valve body governor circuit. The solenoid valve regulates line pressure to produce governor pressure. The average current supplied to the solenoid controls governor pressure. One amp current produces zero kPa/psi governor pressure. Zero amps sets the maximum governor pressure. The powertrain control module (PCM) turns on the bans control relay which supplies electrical power to the solenoid valve. Operating voltage is 12 volts (DC). The PCM controls the ground side of the solenoid using the governor pressure solenoid control circuit. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Description and Operation > Electronic Governor > Page 3296 Governor: Description and Operation Governor Pressure Sensor Fig. 4 The governor pressure sensor measures output pressure of the governor pressure solenoid valve (Fig. 4). The sensor output signal provides the necessary feedback to the PCM. This feedback is needed to adequately control governor pressure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Description and Operation > Electronic Governor > Page 3297 Governor: Description and Operation Governor Body and Transfer Plate Fig. 4 The transfer plate is designed to supply transmission line pressure to the governor pressure solenoid valve and to return governor pressure. The governor pressure solenoid valve is mounted in the governor body. The body is bolted to the lower side of the transfer plate (Fig. 4). The transfer plate channels line pressure to the solenoid valve through the governor body. It also channels governor pressure from the solenoid valve to the governor circuit. It is the solenoid valve that develops the necessary governor pressure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Description and Operation > Electronic Governor > Page 3298 Governor: Description and Operation Governor Pressure Curves There are four governor pressure curves programmed into the transmission control module. The different curves allow the control module to adjust governor pressure for varying conditions. One curve is used for operation when fluid temperature is at, or below, 1°C (30°F). A second curve is used when fluid temperature is at, or above, 10°C (50°F) during normal city or highway driving. A third curve is used during wide-open throttle operation. The fourth curve is used when driving with the transfer case in low range. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T > Component Information > Service and Repair > Replacement Governor: Service and Repair Replacement REMOVAL 1.

The valve temporarily bypasses the clutch piston feed orifice at the start of a 3-4 upshift. This exposes a larger passage into the piston retainer resulting in a much faster clutch fill and apply sequence. The quick fill valve does not bypass the regular clutch feed orifice throughout the 3-4 upshift. Instead, once a predetermined pressure develops within the clutch, the valve closes the bypass. Clutch fill is then completed through the regular feed orifice. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Overdrive Assembly, A/T > Component Information > Service and Repair > Overdrive Unit Overdrive Assembly: Service and Repair Overdrive Unit REMOVAL 1.

The switch is a momentary contact device that signals the PCM to toggle current status of the overdrive function. At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a second time causes normal overdrive operation to be restored and the overdrive lamp to be turned off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The normal position for the control switch is the ON position. The switch must be in this position to energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only when the overdrive switch is turned to the OFF position, or when illuminated by the transmission control module. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Planetary Gears, A/T > Component Information > Specifications > Dimensional Planetary Gears: Specifications Dimensional END PLAY SPECIFICATIONS Planetary end play ............................................................................................................................... .................................................... 0.006-0.048 inch Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Planetary Gears, A/T > Component Information > Specifications > Dimensional > Page 3344 Planetary Gears: Specifications Snap Ring Thickness THICKNESS SPECIFICATIONS Planetary geartrain snap ring (at front of output shaft) .............................................................................................................................................................. ............................................ 0.055-0.059 inch ..................................................................................... ..................................................................................................................... 0.062-0.066 inch Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Pressure Regulating Solenoid, A/T > Component Information > Technical Service Bulletins > Customer Interest for Pressure Regulating Solenoid: > 21-08-99 > Apr > 99 > A/T - Buzz/Whining in Reverse When Cold Pressure Regulating Solenoid: Customer Interest A/T - Buzz/Whining in Reverse When Cold NUMBER: 21-08-99 GROUP: Transmission DATE: April 30, 1999 SUBJECT: "Buzz", "Whining", Or "Moaning" Like Noise From A Cold Transmission When Reverse Is Selected. OVERVIEW: This bulletin involves replacing the transmission regulator valve. MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4.

OVERVIEW: This bulletin involves replacing the transmission regulator valve. MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

The switch is a momentary contact device that signals the PCM to toggle current status of the overdrive function. At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a second time causes normal overdrive operation to be restored and the overdrive lamp to be turned off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The normal position for the control switch is the ON position. The switch must be in this position to energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only when the overdrive switch is turned to the OFF position, or when illuminated by the transmission control module. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Sensors and Switches A/T > Transmission Position Switch/Sensor, A/T > Component Information > Locations Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Sensors and Switches A/T > Transmission Position Switch/Sensor, A/T > Component Information > Locations > Page 3447 Transmission Position Switch/Sensor: Description and Operation TRANSMISSION PARK/NEUTRAL SWITCH-PCM INPUT The park/neutral switch is located on the transmission housing and provides an input to the powertrain control module (PCM).

The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs. The transmission will not allow fourth gear operation until fluid temperature decreases to approximately 110 °C (230 °F). The thermistor is part of the governor pressure sensor assembly and is immersed in transmission fluid at all times. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Sensors and Switches A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation > Page 3463 Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - PCM Input TRANSMISSION TEMPERATURE SENSOR-PCM INPUT This input is used in the shift operation for 4-speed electronic transmissions only.

The retaining clip is then installed back onto the throttle valve cable to lock in the adjustment. A correctly adjusted throttle valve cable, will cause the throttle lever on the transmission to move simultaneously with the throttle body lever from the idle position. Proper adjustment allows simultaneous movement without causing the transmission throttle lever to move ahead of, or lag behind the throttle body lever. THROTTLE VALVE CABLE ADJUSTMENT CHECK 1. Turn ignition key to OFF position. 2. Remove air cleaner. 3. Slide cable off attachment stud on throttle body lever (Fig. 255). 4. Verify that throttle body lever is at curb idle position. Then verify that transmission throttle lever is also at idle (full forward) position. 5. Compare position of cable end to attachment stud on throttle body lever: a. Cable end and attachment stud should be aligned (or centered on one another) to within 1 mm (0.039 inch) in either direction. b. If cable end and attachment stud are misaligned (off center), cable will have to be adjusted as described in following procedure. 6. Reconnect cable end to attachment stud. Then with aid of a helper, observe movement of transmission throttle lever and lever on throttle body. a. If both levers move simultaneously from idle to half-throttle and back to idle position, adjustment is correct. b. If transmission throttle lever moves ahead of, or lags behind throttle body lever, cable adjustment will be necessary. Or, if throttle body lever prevents transmission lever from returning to closed position, cable adjustment will be necessary. THROTTLE VALVE CABLE ADJUSTMENT PROCEDURE 1. Turn ignition switch to OFF position and shift into Park. 2. Remove air cleaner. 3. Disconnect cable end from attachment stud on throttle body. Carefully slide cable off stud. Do not pull or pry cable off. 4. Verify that transmission throttle lever is in idle (full forward) position. Then be sure lever on throttle body is at curb idle position. 5. Insert a small screwdriver under edge of retaining clip and remove retaining clip. 6. Center cable end on attachment stud to within 1 mm (0.039 inch). NOTE: Be sure that as the cable is pulled forward and centered on the throttle lever stud, the cable housing moves smoothly with the cable. Due to the angle at which the cable housing enters the spring housing, the cable housing may bind slightly and create an incorrect adjustment. 7. Install retaining clip onto cable housing. 8. Check cable adjustment. Be sure transmission throttle lever and lever on throttle body move simultaneously and as described in cable adjustment checking procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter > Component Information > Specifications Torque Converter: Specifications Bolt, torque convertor 23 ft.lb Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter > Component Information > Specifications > Page 3485 Torque Converter: Service and Repair REMOVAL 1.

The valve prevents fluid from draining from the converter into the cooler and lines when the vehicle is shut down for lengthy periods. Production valves have a hose nipple at one end, while the opposite end is threaded for a flare fitting. All valves have an arrow (or similar mark) to indicate direction of flow through the valve. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Check Valve > Component Information > Description and Operation > Page 3489 Torque Converter Check Valve: Service and Repair The converter drainback check valve is located in the cooler outlet (pressure) line near the radiator tank. The valve prevents fluid drainback when the vehicle is parked for lengthy periods. The valve check ball is spring loaded and has an opening pressure of approximately 2 psi. The valve is serviced as an assembly; it is not repairable. Do not clean the valve if restricted, or contaminated by sludge, or debris. If the valve fails, or if a transmission malfunction occurs that generates significant amounts of sludge and/or clutch particles and metal shavings, the valve must be replaced. The valve must be removed whenever the cooler and lines are reverse flushed. The valve can be flow tested when necessary. The procedure is exactly the same as for flow testing a cooler. If the valve is restricted, installed backwards, or in the wrong line, it will cause an overheating condition and possible transmission failure. CAUTION: The drainback valve is a one-way flow device. It must be properly oriented in terms of flow direction for the cooler to function properly. The valve must be installed in the pressure line. Otherwise flow will be blocked and would cause an overheating condition and eventual transmission failure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch, A/T > Component Information > Description and Operation Torque Converter Clutch: Description and Operation Converter clutch engagement in third or fourth gear range is controlled by sensor inputs to the powertrain control module. Inputs that determine clutch engagement are: coolant temperature, engine rpm, vehicle speed, throttle position, and manifold vacuum. The torque converter clutch is engaged by the clutch solenoid on the valve body. The clutch can be engaged in third and fourth gear ranges depending on overdrive control switch position. If the overdrive control switch is in the normal ON position, the clutch will engage after the shift to fourth gear, and above approximately 72 km/in (45 mph). If the control switch is in the OFF position, the clutch will engage after the shift to third gear, at approximately 56 km/in (35 mph) at light throttle. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Locations O/D (3-4) Solenoid, TCC Solenoid, Governor Pressure Sensor, Governor Pressure Solenoid Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Torque Converter Clutch Solenoid, A/T > Component Information > Locations > Page 3496 Torque Converter Clutch Solenoid: Description and Operation TORQUE CONVERTOR CLUTCH (TCC) SOLENOID-PCM OUTPUT This circuit controls operation of the transmission mounted torque convertor clutch (TCC) solenoid used for torque convertor engagement.

The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs. The transmission will not allow fourth gear operation until fluid temperature decreases to approximately 110 °C (230 °F). The thermistor is part of the governor pressure sensor assembly and is immersed in transmission fluid at all times. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation > Page 3535 Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - PCM Input TRANSMISSION TEMPERATURE SENSOR-PCM INPUT This input is used in the shift operation for 4-speed electronic transmissions only.

The system performs five basic functions which are: pressure supply, pressure regulation, flow control, clutch/band application, and lubrication. PRESSURE REGULATION The pressure regulator valve maintains line pressure. The amount of pressure developed is controlled by throttle pressure which is dependent on the degree of throttle opening. The regulator valve is located in the valve body. The throttle valve determines line pressure and shift speed. Governor pressure increases in proportion to vehicle speed. The throttle valve controls upshift and downshift speeds by regulating pressure according to throttle position. Shift Valve Flow Control The manual valve is operated by the gearshift linkage and provides the operating range selected by the driver. The 1-2 shift valve provides 1-2 or 2-1 shifts and the 2-3 shift valve provides 2-3 or 3-2 shifts. The kickdown valve provides forced 3-2 or 3-1 downshifts depending on vehicle speed. Downshifts occur when the throttle is opened beyond downshift detent position. Detent is reached just before wide open throttle position. The 2-3 valve throttle pressure plug provides 3-2 downshifts at varying throttle openings depending on vehicle speed. The 1-2 shift control valve transmits 1-2 shift pressure to the accumulator piston. This controls kickdown band capacity on 1-2 upshifts and 3-2 downshifts. The 3-4 shift, quick fill, and timing valves plus the 3-4 accumulator, are only actuated when the overdrive solenoid is energized. The solenoid contains a check ball that controls a vent port to the 3-4 valves. The check ball either diverts line pressure away from or directly to the 3-4 valves. The limit valve determines maximum speed at which a 3-2 part throttle kickdown can be made. On transmissions without a limit valve, maximum speed for a 3-2 kickdown is at detent position. The 2-3 shuttle valve has two functions. The first is fast front band release and smooth engagement during lift-foot 2-3 upshifts. The second is to regulate front clutch and band application during 3-2 downshifts. The 3-4 timing valve is moved by line pressure coming through the 3-4 shift valve. The timing valve holds the 2-3 shift valve in an upshift position. The purpose is to prevent the 2-3 valve from up or downshifting before the 3-4 valve. The 3-4 accumulator is mounted on the overdrive housing and performs the same function as the 2-3 accumulator; it is used to smooth engagement during a 3-4 shift. The switch valve directs fluid apply pressure to the converter clutch in one position and releases it in the opposite position. It also directs oil to the cooling and lube circuits. The switch valve regulates oil pressure to the torque converter by limiting maximum oil pressure to 130 psi. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Description and Operation > Hydraulic Control System > Page 3557 Valve Body: Description and Operation Shift Valve Operation The shift valves are moved by a combination of throttle and governor pressure. The governor pressure is generated by electrical components. The conditions under which a shift to fourth will not occur are: Overdrive switch is Off - Transmission fluid temperature is below 10 °C (50 °F) or above 121 °C (250 °F) - Shift to third not yet completed - Vehicle speed too low for 3-4 shift to occur - Battery temperature below -5 °F. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Description and Operation > Page 3558 Valve Body: Adjustments For pressure adjustment procedures, refer to Automatic Transmission/Transaxle, Adjustment. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Service and Repair > Removal and Installation Valve Body: Service and Repair Removal and Installation OVERVIEW The valve body can be removed for service without having to remove the transmission assembly.

Do not use gasoline, kerosene, or any type of caustic solution. Do not immerse any of the electrical components in cleaning solution. Clean the governor solenoid and sensor and the dual solenoid and harness assembly by wiping them off with dry shop towels only. Dry all except the electrical parts with compressed air. Make sure all passages are clean and free from obstructions. Do not use rags or shop towels to dry or wipe off valve body components. Lint from these materials can stick to valve body parts, interfere with valve operation, and clog filters and fluid passages. Wipe the governor pressure sensor and solenoid valve with dry, lint free shop towels only. The O-rings on the sensor and solenoid valve are the only serviceable components. Be sure the vent ports in the solenoid valve are open and not blocked by dirt or debris. Replace the valve and/or sensor only when DRB scan tool diagnosis indicates this is necessary. Or, if either part has sustained physical damage (dented, deformed, broken, etc.). CAUTION: Do not turn the small screw at the end of the solenoid valve for any reason. Turning the screw in either direction will ruin solenoid calibration and result in solenoid failure. In addition, the filter on the solenoid valve is NOT serviceable. Do not try to remove the filter as this will damage the valve housing. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Service and Repair > Removal and Installation > Page 3589 Upper Housing Valves, Plugs, Springs And Brackets Inspect the throttle and manual valve levers and shafts. Do not attempt to straighten a bent shaft or correct a loose lever. Replace these components if worn, bent, loose or damaged in any way. Inspect all of the valve body mating surfaces for scratches, nicks, burrs, or distortion. Use a straightedge to check surface flatness. Minor scratches may be removed with crocus cloth using only very light pressure. Minor distortion of a valve body mating surface may be corrected by smoothing the surface with a sheet of crocus cloth. Position the crocus cloth on a surface plate, sheet of plate glass or equally flat surface. If distortion is severe or any surfaces are heavily scored, the valve body will have to be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Service and Repair > Removal and Installation > Page 3590 CAUTION: Many of the valves and plugs, such as the throttle valve, shuttle valve plug, 1-2 shift valve and 1-2 governor plug, are made of coated aluminum. Aluminum components are identified by the dark color of the special coating applied to the surface (or by testing with a magnet). Do not sand aluminum valves or plugs under any circumstances. This practice could damage the special coating causing the valves/plugs to stick and bind. Inspect the valves and plugs for scratches, burrs, nicks, or scores. Minor surface scratches on steel valves and plugs can be removed with crocus cloth but do not round off the edges of the valve or plug lands. Maintaining sharpness of these edges is vitally important. The edges prevent foreign matter from lodging between the valves and plugs and the bore. Inspect all the valve and plug bores in the valve body. Use a penlight to view the bore interiors. Replace the valve body if any bores are distorted or scored. Inspect all of the valve body springs. The springs must be free of distortion, warpage or broken coils. Check the two separator plates for distortion or damage of any kind. Inspect the upper housing, lower housing, 3-4 accumulator housing, and transfer plate carefully. Be sure all fluid passages are clean and clear. Check condition of the upper housing and transfer plate check balls as well. The check balls and ball seats must not be worn or damaged. Trial fit each valve and plug in its bore to check freedom of operation. When clean and dry, the valves and plugs should drop freely into the bores. Valve body bores do not change dimensionally with use. If the valve body functioned correctly when new, it will continue to operate properly after cleaning and inspection. It should not be necessary to replace a valve body assembly unless it is damaged in handling. The only serviceable valve body components are listed below. The remaining valve body components are serviced only as part of a complete valve body assembly. Serviceable parts are: - dual solenoid and harness assembly - solenoid gasket - solenoid case connector O-rings and shoulder bolt - switch valve and spring - pressure adjusting screw and bracket assembly - throttle lever - manual lever and shaft seal - throttle lever shaft seal, washer, and E-clip - fluid filter and screws - detent ball and spring - valve body screws - governor pressure solenoid - governor pressure sensor and retaining clip - park lock rod and E-clip Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T > Component Information > Service and Repair > Removal and Installation > Page 3591 Valve Body: Service and Repair Assembly Assembly Precaution CAUTION: Do not force valves or plugs into place during reassembly. If the valve body bores, valves and plugs are free of distortion or burrs, the valve body components should all slide into place easily. In addition, do not overtighten the transfer plate and valve body screws during reassembly. Overtightening can distort the housings resulting in valve sticking, cross leakage and unsatisfactory operation. Tighten valve body screws to recommended torque only.

NOTE: Safety Recall No.870 and 892 combine the axle vent hose clip with another repair. Dealers should verify which recall the vehicle is involved in prior to completing the service procedure. ^ Safety Recall No.870 applies to 1997-2000 model year trucks equipped with a 2.5L engine and involves the axle vent hose clip and a power steering hose bracket. ^ Safety Recall No.892 applies to 1997 model year club cab (131" W.B.) trucks and involves the axle vent hose clip and a rear fuel tube isolator. IMPORTANT: Some of the involved vehicles may be in dealer new vehicle inventory. Federal law requires you to stop sale and complete this recall service on these vehicles before retail delivery. Dealers should also consider this requirement to apply to used vehicle inventory and should perform this recall on vehicles in for service. Involved vehicles can be determined by using the DIAL VIP System. Subject The rear brake hose on about 309,000 of the above vehicles may contact the rear axle vent hose. Prolonged brake hose contact may cause the hose to rub through and leak, resulting in a partial brake system loss and increased stopping distance. The increased stopping distance can cause an accident without warning. Repair The rear brake hose must be inspected for evidence of contact and/or wear. The rear axle vent hose must also be shortened and repositioned. Brake hoses that have ribs worn smooth from contact with the vent hose must be replaced. Alternate Transportation If inspection determines that brake hose replacement is required and the vehicle must be held overnight, dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle.

NOTE: Safety Recall No.870 and 892 combine the axle vent hose clip with another repair. Dealers should verify which recall the vehicle is involved in prior to completing the service procedure. ^ Safety Recall No.870 applies to 1997-2000 model year trucks equipped with a 2.5L engine and involves the axle vent hose clip and a power steering hose bracket. ^ Safety Recall No.892 applies to 1997 model year club cab (131" W.B.) trucks and involves the axle vent hose clip and a rear fuel tube isolator. IMPORTANT: Some of the involved vehicles may be in dealer new vehicle inventory. Federal law requires you to stop sale and complete this recall service on these vehicles before retail delivery. Dealers should also consider this requirement to apply to used vehicle inventory and should perform this recall on vehicles in for service. Involved vehicles can be determined by using the DIAL VIP System. Subject The rear brake hose on about 309,000 of the above vehicles may contact the rear axle vent hose. Prolonged brake hose contact may cause the hose to rub through and leak, resulting in a partial brake system loss and increased stopping distance. The increased stopping distance can cause an accident without warning. Repair The rear brake hose must be inspected for evidence of contact and/or wear. The rear axle vent hose must also be shortened and repositioned. Brake hoses that have ribs worn smooth from contact with the vent hose must be replaced. Alternate Transportation If inspection determines that brake hose replacement is required and the vehicle must be held overnight, dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle.

DISCUSSION: The axle lubricant used in all corporate axles was changed in formulation starting at the beginning of the 1998 model year. The corporate axles involved include: the 8.25 and 9.25 rear axles, and the C205F front axle. The new lubricant in use is SAE 75W-90 p/n 05010320AA. The lubricant change was made as a fuel economy improvement. The new axle lubricant is more chemically aggressive/reactive when in contact with the previous used Room Temperature Vulcanizable (RTV) sealant. Because of this condition, the RTV used in assembly of the pan/cover to the axle housing was revised and improved. When re-sealing axle covers, using the proper sealing material to minimize any potential sealant breakdown is important. The only recommended sealing material for all corporate axle covers is MOPAR RTV Sealant, p/n 05013477M. This RTV is red/orange in color. NOTE: IF SAE 75W-90 LUBRICANT IS USED TO REFILL ANY CORPORATE AXLE, THEN THE RED/ORANGE MOPAR RTV SEALANT, P/N 05013477AA, SHOULD BE USED TO SEAL THE COVER TO THE AXLE HOUSING. To optimize sealant performance and enhance adhesion, flanges should be clean and free of residual lubricant. The mating flanges should first be cleaned of any excess old RTV using a plastic putty knife. Final cleaning/degreasing shall be done by spraying MOPAR Brake Parts Cleaner, p/n 04549623, on the carrier and cover flanges, followed by a wipe with a clean dry cloth. Care should be taken to avoid spraying the parts cleaner inside the carrier. Once the RTV has been applied, the axle cover is to be installed to the housing within 3 to 5 minutes to prevent skinning over of the RTV. NOTE: IF THE AXLE COVER IS NOT INSTALLED WITHIN THE 3 TO 5 MINUTE TIME FRAME, THE CARRIER COVER FACE MUST BE RECLEANED AND NEW RTV APPLIED, OR ADHESION QUALITY WILL BE COMPROMISED. Immediately install the cover attaching bolts and tighten them to the specified torque to prevent a shimming effect by the RTV.

DISCUSSION: The customer or servicing technician may notice a milky-like appearance to the 9.25 inch rear axle fluid. This condition may be brought to the customer's attention when the axle fluid is inspected during normal service. Other than the concern for the color of axle fluid, the customer does not experience any other axle complaint. The customer or servicing technician may be concerned because a milky-like appearance to the axle fluid may also indicate the presence of water. The cause of the milky-like appearance to the axle fluid may be due to the use of a white color gear marking compound during the axle assembly process. Axle gear marking compound is used to verify correct ring and pinion gear alignment during manufacture. The 9.25 inch rear axle is assembled on two different assembly lines. To visually distinguish axles from each assembly line, one assembly line used a white color gear marking compound (versus yellow). Half of the axles that were assembled during the above time frame may have the white gear marking compound mixed with the rear axle fluid. The white color gear marking compound is no longer in use by the axle assembly plant. NOTE: IF THE MILKY-LIKE REAR AXLE FLUID APPEARANCE IS DUE TO THE WHITE GEAR MARKING COMPOUND, THEN NO SERVICE ACTION IS NECESSARY TO ADDRESS THIS CONDITION. If the milky-like rear axle fluid appearance is due to the presence of water, then the rear axle will require service. Axle fluid, contaminated with water, may cause rust and damage to the internal components of the axle. Any water in the axle fluid will begin to boil off (reach its gaseous state) before the oil. Placing a small sample of axle fluid on a hot steel surface (around 100C or 212F) will cause any water that may be present in the fluid to boil off with a "sizzle-like" sound.

The use of the correct replacement parts helps to ensure safe operation. All fasteners must be torqued to the specified values for safe operation. Fig. 3 Also make alignment reference marks on the propeller shaft yoke and axle, or transmission, yoke prior to servicing. This helps to eliminate possible vibration. CAUTION: Do not allow the propeller shaft to drop or hang from any propeller shaft joint during removal. Attach the propeller shaft to the vehicle underside with wire to prevent damage to the joints. CAUTION: It is very important to protect the external machined surface of the slip yoke from damage during and after propeller shaft removal. If the yoke is damaged, the transmission extension seal may be damaged and therefore cause a leak. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Description and Operation > General Information Drive/Propeller Shaft: Description and Operation General Information Fig. 1 The propeller shaft transmits power from one point to another in a smooth and continuous action. The shaft is designed to send torque through an angle from the transmission (transfer case on 4WD vehicles) to the axle. The propeller shaft must operate through constantly changing relative angles between the transmission and axle. It must also be capable of changing length while transmitting torque. The axle rides suspended by springs in a floating motion. This means the propeller shaft must be able to contract, expand and change operating angles when going over various road surfaces. This is accomplished through universal joints, which permit the propeller shaft to operate at different angles. The slip joints (or yokes) permit contraction or expansion. Tubular propeller shafts are balanced by the manufacturer with weights spot welded to the tube. The propeller shaft is designed and built with the yoke lugs in line with each other. This is called phasing. This design produces the smoothest running condition. An out of phase shaft can cause a vibration. Before undercoating a vehicle, the propeller shaft and the U-joints should be removed if possible. If removal is not possible, make sure that the propeller shaft and U-joints are fully covered. This will prevent the undercoating from causing an out of balance condition and vibration. CAUTION: Use exact replacement parts for attaching the propeller shafts. This will ensure safe operation. The specified torque must always be applied when tightening the fasteners. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Description and Operation > General Information > Page 3728 Drive/Propeller Shaft: Description and Operation Center Bearings Vehicles equipped with a two-piece propeller shaft uses a rubber insulated center bearing. The bearing is used to support the shafts where they are joined together. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Description and Operation > General Information > Page 3729 Drive/Propeller Shaft: Description and Operation Lubrication The slip yoke on the front propeller shaft is equipped with a lubrication fitting. Use a multi-purpose NLGI Grade 2 EP lubricant. The factory installed universal joints are lubricated for the life of the vehicle and do not need lubrication. All universal joints should be inspected for leakage and damage each time the vehicle is serviced. If seal leakage or damage exists, the universal joint should be replaced. Refer to Maintenance, for additional information. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Description and Operation > General Information > Page 3730 Drive/Propeller Shaft: Description and Operation Propeller Shaft Joint Angle When two shafts come together at a common joint, the bend that is formed is called the operating angle. The larger the angle, the larger the amount of angular acceleration and deceleration of the joint. This speeding up and slowing down of the joint must be cancelled to produce a smooth power flow. This is done through the phasing of a propeller shaft and ensuring that the proper propeller shaft joint working angles are maintained. A propeller shaft is properly phased when the yoke ends are in the same plane, or in line. A twisted shaft will make the yokes out of phase and cause a noticeable vibration. When taking propeller shaft joint angle measurements, or checking the phasing, of two piece shafts, consider each shaft separately. Ideally the driveline system should have; Angles that are equal or opposite within 1 degree of each other. - Have a 3 degree maximum operating angle. - Have at least a 1/2 degree continuous operating (propeller shaft) angle. Fig. 1 Engine speed (rpm) is the main factor in determining the maximum allowable operating angle. As a guide to the maximum normal operating angles refer to. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures > Page 3733 Drive/Propeller Shaft: Component Tests and General Diagnostics Vibration Tires that are out-of-round, or wheels that are unbalanced, will cause a low frequency vibration. Refer to Tires and Wheels, for additional information. Brake drums that are unbalanced will cause a harsh, low frequency vibration. Refer to Brakes and Traction Control, for additional information. Driveline vibration can also result from loose or damaged engine mounts. Refer to Engines, for additional information. Propeller shaft vibration increases as the vehicle speed is increased. A vibration that occurs within a specific speed range is not usually caused by a propeller shaft being unbalanced. Defective universal joints, or an incorrect propeller shaft angle, are usually the cause of such a vibration. Unbalance NOTE: Removing and re-indexing the propeller shaft 180° relative to the yoke may eliminate some vibrations. If propeller shaft is suspected of being unbalanced, it can be verified with the following procedure: 1. Raise the vehicle. 2. Clean all the foreign material from the propeller shaft and the universal joints. 3. Inspect the propeller shaft for missing balance weights, broken welds, and bent areas. If the propeller shaft is bent, it must be replaced. 4. Inspect the universal joints to ensure that they are not worn, are properly installed, and are correctly aligned with the shaft. 5. Check the universal joint clamp screws torque. 6. Remove the wheels and tires. Install the wheel lug mats to retain the brake drums or rotors. 7. Mark and number the shaft six inches from the yoke end at four positions 90° apart. Fig. 4 8. Run and accelerate the vehicle until vibration occurs. Note the intensity and speed the vibration occurred. Stop the engine. 9. Install a screw clamp at position 1. 10. Start the engine and re-check for vibration. If there is little or no change in vibration, move the clamp to one of the other three positions. Repeat the vibration test. 11. If there is no difference in vibration at the other positions, the source of the vibration may not be propeller shaft. Fig. 5 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller Shaft > Component Information > Testing and Inspection > Symptom Related Diagnostic Procedures > Page 3734 12. If the vibration decreased' install a second clamp and repeat the test. Fig. 6 13. If the additional clamp causes an additional vibration, separate the clamps (1/4 inch above and below the mark). Repeat the vibration test. 14. Increase distance between the clamp screws and repeat the test until the amount of vibration is at the lowest level. Bend the slack end of the clamps so the screws will not loosen. 15. If the vibration remains unacceptable, apply the same steps to the front end of the propeller shaft. 16. Install the wheel and tires. Lower the vehicle. Runout 1. Remove dirt, rust, paint, and undercoating from the propeller shaft surface where the dial indicator will contact the shaft. 2. The dial indicator must be installed perpendicular to the shaft surface. 3. Measure runout at the center and ends of the shaft sufficiently far away from weld areas to ensure that the effects of the weld process will not enter into the measurements. 4. Refer to Runout Specifications chart. 5. If the propeller shaft runout is out of specification, remove the propeller shaft, index the shaft 180°, and re-install the propeller shaft. Measure shaft runout again. 6. If the propeller shaft runout is now within specifications, mark the shaft and yokes for proper orientation. 7. If the propeller shaft runout is not within specifications, verify that the runout of the transmission/ transfer case and axle are within specifications. Correct as necessary and re-measure propeller shaft runout. 8. Replace the propeller shaft if the runout still exceeds the limits.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

The switch is a momentary contact device that signals the PCM to toggle current status of the overdrive function. At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a second time causes normal overdrive operation to be restored and the overdrive lamp to be turned off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The normal position for the control switch is the ON position. The switch must be in this position to energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only when the overdrive switch is turned to the OFF position, or when illuminated by the transmission control module. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Position Switch/Sensor, A/T > Component Information > Locations Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Position Switch/Sensor, A/T > Component Information > Locations > Page 3844 Transmission Position Switch/Sensor: Description and Operation TRANSMISSION PARK/NEUTRAL SWITCH-PCM INPUT The park/neutral switch is located on the transmission housing and provides an input to the powertrain control module (PCM).

The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs. The transmission will not allow fourth gear operation until fluid temperature decreases to approximately 110 °C (230 °F). The thermistor is part of the governor pressure sensor assembly and is immersed in transmission fluid at all times. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Sensors and Switches - Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation > Page 3860 Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - PCM Input TRANSMISSION TEMPERATURE SENSOR-PCM INPUT This input is used in the shift operation for 4-speed electronic transmissions only.

OVERVIEW: This bulletin involves replacing the transmission regulator valve. MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

OVERVIEW: This bulletin involves replacing the transmission regulator valve. MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE REVISED MODEL YEARS. SUBJECT: Erroneous MIL Illumination For P1763 - Trans. Governor Pressure Sensor Volts Too High OVERVIEW: This bulletin involves selectively erasing and reprogramming the JTEC Powertrain Control Module (PCM) with new software (calibration change 96Cal18, 97Cal18, 98Cal12, and 99Cal14). MODELS: **1996** - 1999 (AB) Ram Van **1996** - 1999 (AN) Dakota **1996** - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango **1997** - 1999 (TJ) Wrangler **1996** 1999 (XJ) Cherokee **1996** - 1998 (ZJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH AN RE SERIES AUTOMATIC TRANSMISSION BUILT BEFORE DECEMBER 18, 1998 (MDH 1218XX). SYMPTOM/CONDITION: Some vehicles may exhibit a MIL illumination with a Diagnostic Trouble Code (DTC) of P1763 - Transmission Governor Pressure Sensor Volts Too High. The vehicle operator may experience slower than normal vehicle accelerations because the transmission may have temporarily entered its third gear "Limp-In" mode as a result of the DTC. The "Limp-In" mode may last until the vehicle owner cycles the ignition key. The technician may not detect a problem with the automatic transmission during a diagnostic test or test drive. The MIL is caused by an increase in hydraulic pressure. The increased hydraulic pressure is the result of a new valve body machining process, which entered into production January 1, 1998. This condition will occur most often with vehicles that were built between January 1, 1998 and December 18, 1998. Vehicles built prior to January 1,1998 may also experience this condition if the valve body or the transmission assembly is replaced with components built after January 1, 1998. DIAGNOSIS: Using the Mopar Diagnostic System (MDS2) and or the Diagnostic Scan Tool (DRB III(R)), with the appropriate Diagnostic Procedures Manual, verify that all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If no DTC's are present, and the above symptom has been experienced, perform the Repair Procedure.

The switch is a momentary contact device that signals the PCM to toggle current status of the overdrive function. At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a second time causes normal overdrive operation to be restored and the overdrive lamp to be turned off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The normal position for the control switch is the ON position. The switch must be in this position to energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only when the overdrive switch is turned to the OFF position, or when illuminated by the transmission control module. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Position Switch/Sensor, A/T > Component Information > Locations Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Position Switch/Sensor, A/T > Component Information > Locations > Page 3958 Transmission Position Switch/Sensor: Description and Operation TRANSMISSION PARK/NEUTRAL SWITCH-PCM INPUT The park/neutral switch is located on the transmission housing and provides an input to the powertrain control module (PCM).

The sensor is positioned over the park gear and monitors transmission output shaft rotating speed. Speed sensor signals are triggered by the park gear lugs as they rotate past the sensor pickup face. Input signals from the sensor are sent to the transmission control module for processing. The vehicle speed sensor also serves as a backup for the transmission speed sensor. Signals from this sensor are shared with the powertrain control module. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Speed Sensor, A/T > Component Information > Description and Operation > Page 3968 Transmission Speed Sensor: Service and Repair Removal Transmission Speed Sensor Removal Installation 1.

The temperature readings are used to control engagement of the fourth gear overdrive clutch, the converter clutch, and governor pressure. Normal resistance value for the thermistor at room temperature is approximately 1000 ohms. The PCM prevents engagement of the converter clutch and overdrive clutch, when fluid temperature is below approximately 10 °C (50 °F). If fluid temperature exceeds 126 °C (260 °F), the PCM causes a 4-3 downshift and engage the converter clutch. Engagement is according to the third gear converter clutch engagement schedule. The overdrive OFF lamp in the instrument panel illuminates when the shift back to third occurs. The transmission will not allow fourth gear operation until fluid temperature decreases to approximately 110 °C (230 °F). The thermistor is part of the governor pressure sensor assembly and is immersed in transmission fluid at all times. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Transmission and Drivetrain > Transmission Control Systems > Sensors and Switches Transmission and Drivetrain > Sensors and Switches - A/T > Transmission Temperature Sensor/Switch, A/T > Component Information > Description and Operation > Transmission Temperature Sensor - Description and Operation > Page 3974 Transmission Temperature Sensor/Switch: Description and Operation Transmission Temperature Sensor - PCM Input TRANSMISSION TEMPERATURE SENSOR-PCM INPUT This input is used in the shift operation for 4-speed electronic transmissions only.

The modulated hydraulic pressure is used to prevent wheel lock up during braking. The CAB also provides a vehicle speed signal (VSS) to the powertrain control module. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 4011 Electronic Brake Control Module: Description and Operation With Four Wheel Antilock Brakes CAB/HCU The Controller Antilock Brakes (CAB) is mounted on the top of the hydraulic control unit. The CAB operates the ABS system and is separate from other vehicle electrical circuits. CAB voltage source is through the ignition switch in the RUN position. The CAB contains dual microprocessors. A logic block in each microprocessor receives identical sensor signals. These signals are processed and compared simultaneously. The CAB contains a self check program that illuminates the ABS warning light when a system fault is detected. Faults are stored in a diagnostic program memory and are accessible with the DRB scan tool. ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50 times. Stored faults are not erased if the battery is disconnected. NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 4012 Electronic Brake Control Module: Description and Operation With Rear Wheel Antilock Brakes RWAL Cab The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics. - Monitor the RWAL brake system for proper operation. - Control the RWAL valve solenoids. NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB. SYSTEM SELF-TEST When the ignition switch is turned-on the microprocessor RAM and ROM are tested. If an error occurs during the test, a DTC will be set into the RAM memory. However it is possible the DTC will not be stored in memory if the error has occurred in the RAM module were the DTC's are stored. Also it is possible a DTC may not be stored if the error has occurred in the ROM which signals the RAM to store the DTC. CAB INPUTS The CAB continuously monitors the speed of the differential ring gear by monitoring signals generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency when it recognizes the ring gear decelerating too rapidly. The CAB monitors the following inputs to determine when a wheel locking tendency may exists: Rear Wheel Speed Sensor - Brake Lamp Switch - Brake Warning Lamp Switch - Reset Switch - 4WD Switch (If equipped) CAB OUTPUTS The CAB controls the following outputs for antilock braking and brake warning information: RWAL Valve - ABS Warning Lamp - Brake Warning Lamp VALVE REAR WHEEL ANTILOCK BRAKES If the CAB senses that rear wheel speed deceleration is excessive, it will energize an isolation solenoid by providing battery voltage to the solenoid. This prevents a further increase of driver induced brake pressure to the rear wheels. If this initial action is not enough to prevent rear wheel lock-up, the CAB will momentarily energize a dump solenoid (the CAB energizes the dump solenoid by providing battery voltage to the solenoid). This opens the dump valve to vent a small amount of isolated rear brake pressure to an accumulator. The action of fluid moving to the accumulator reduces the isolated brake pressure at the wheel cylinders. The dump (pressure venting) cycle is limited to very short time periods (milliseconds). The CAB will pulse the dump valve until rear wheel deceleration matches the desired slip rate programmed into the CAB. The system will switch to normal braking once wheel locking tendencies are no longer present. A predetermined maximum number of consecutive dump cycles can be performed during any RWAL stop. If excessive dump cycles occur, a DTC will be set and stored in the CAB memory. If during a RWAL stop, the driver releases the brake pedal, the reset switch contacts will open. This signal to the CAB is an indication that pressure has equalized across the RWAL valve. The CAB will then reset the dump cycle counter in anticipation of the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 4013 next RWAL stop. Additionally, any fluid stored in the accumulator will force its way past the dump valve, back into the hydraulic circuit and return to the master cylinder. A fuse internal to the CAB, provides a fail-safe device which prevents unwanted control over the isolation and dump solenoids. The fuse is in series with the isolation and dump solenoids output circuits. If the internal fuse is open, the CAB cannot provide voltage to energize either solenoid and RWAL stops are prevented. If the fuse is open, the braking system will operate normally but without antilock control over rear brake pressure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Electronic Brake Control Module > Component Information > Service and Repair > Four Wheel Antilock Brake System Electronic Brake Control Module: Service and Repair Four Wheel Antilock Brake System NOTE: If the Controller Antilock Brakes (CAB) needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB.

The pump, motor, and accumulators are combined into an assembly attached to the valve body. The accumulators store the extra fluid which had to be dumped from the brakes. This is done to prevent the wheels from locking up. The pump provides the fluid volume needed and is operated by a DC type motor. The motor is controlled by the Controller Antilock Brakes (CAB). The valve body contains the solenoid valves. The valves modulate brake pressure during antilock braking and are controlled by the CAB. The HCU provides three channel pressure control to the front and rear brakes. One channel controls the rear wheel brakes in tandem. The two remaining channels control the front wheel brakes individually. During antilock braking, the solenoid valves are opened and closed as needed. The valves are not static. They are cycled rapidly and continuously to modulate pressure and control wheel slip and deceleration. During normal braking, the HCU solenoid valves and pump are not activated. The master cylinder and power booster operate the same as a vehicle without an ABS brake system. During antilock braking, solenoid valve pressure modulation occurs in three stages, pressure decrease, pressure hold, and pressure increase. The valves are all contained in the valve body portion of the HCU. PRESSURE DECREASE The inlet valve is closed and the outlet valve is opened during the pressure decrease cycle. A pressure decrease cycle is initiated when speed sensor signals indicate high wheel slip at one or more wheels. At this point, the CAB closes the inlet to prevent the driver from further increasing the brake pressure and locking the brakes. The CAB then opens the outlet valve, which also opens the return circuit to the accumulators. Fluid pressure is allowed to bleed off (decrease) as needed to prevent wheel lock. Once the period of high wheel slip has ended, the CAB closes the outlet valve and begins a pressure increase or hold cycle as needed. PRESSURE HOLD Both solenoid valves are closed in the pressure hold cycle. Fluid apply pressure in the control channel is maintained at a constant rate. The CAB maintains the hold cycle until sensor inputs indicate a pressure change is necessary. PRESSURE INCREASE The inlet valve is open and the outlet valve is closed during the pressure increase cycle. The pressure increase cycle is used to counteract unequal wheel speeds. This cycle controls re-application of fluid apply pressure due to changing road surfaces or wheel speed. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Hydraulic Control Assembly - Antilock Brakes > Component Information > Description and Operation > With Four Wheel Antilock Brakes > Page 4024 Hydraulic Control Assembly - Antilock Brakes: Description and Operation With Rear Wheel Antilock Brakes RWAL Cab The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and controlling the ABS brake system operation.

However it is possible the DTC will not be stored in memory if the error has occurred in the RAM module were the DTC's are stored.

A sensor is mounted to each front steering knuckles. The third sensor is mounted on top of the rear axle differential housing. The sensor is a magnet coil that is mounted over a tone wheel front/exciter ring rear with an air gap between them. The sensors measure the wheel speed by monitoring the rotation of the tone wheels front/exciter ring rear. As the teeth of the tone wheels front/exciter ring rear move through the magnetic field of the sensor an AC voltage is generated. This signal frequency increases or decreases proportionally to the speed of the wheel. The CAB monitors these signals for changes in wheel deceleration. If the CAB detects a sudden wheel or wheels deceleration within a predetermined amount the CAB will activate the ABS system. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Wheel Speed Sensor > Component Information > Description and Operation > Four Wheel Antilock Brakes > Page 4040 Wheel Speed Sensor: Description and Operation Rear Wheel Antilock Brakes Rear Wheel Speed Sensor Location The rear Wheel Speed Sensor (WSS) is mounted in the rear differential housing. The WSS consists of a magnet surrounded by windings from a single strand of wire. The sensor sends a small AC signal to the CAB. This signal is generated by magnetic induction. The magnetic induction is created when a toothed sensor ring (exciter ring or tone wheel) passes the stationary magnetic WSS. Exciter Ring Location The exciter ring is press fitted onto the differential carrier next to the final drive ring gear. For replacement procedure of the exciter ring, refer to Transmission and Drivetrain. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Wheel Speed Sensor > Component Information > Description and Operation > Four Wheel Antilock Brakes > Page 4041 Operation Of The Wheel Speed Sensor When the ring gear is rotated, the exciter ring passes the tip of the WSS. As the exciter ring passes the tip of the WSS, the magnetic lines of force of the sensor are cut, causing the magnetic field to be moved across the sensor's windings. This, in turn causes current to flow through the WSS circuit. Every time a tooth of the exciter ring passes the tip of the WSS, an AC signal is generated. Each AC signal (positive to negative signal or sinewave) is interpreted by the CAB. It then compares the frequency of the sinewave to a time value to calculate vehicle speed. The CAB continues to monitor the frequency to determine a deceleration rate that would indicate a possible wheel-locking tendency. The signal strength of any magnetic induction sensor is directly affected by: Magnetic field strength; the stronger the magnetic field, the stronger the signal - Number of windings in the sensor; more windings provide a stronger signal - Exciter ring speed; the faster the exciter ring rotates, the stronger the signal will be - Distance between the exciter ring teeth and WSS; the closer the WSS is to the exciter ring, the stronger the signal will be The rear WSS is not adjustable. A clearance specification has been established for manufacturing tolerances. If the clearance is not within these specifications, then either the WSS or other components may be damaged. The clearance between the WSS and the exciter ring is 0.005-0.050 inch. Data Link Connector - Typical The assembly plant performs a "Rolls Test" on every vehicle that leaves the assembly plant. One of the tests performed is a test of the WSS. To properly test the sensor, the assembly plant connects test equipment to the Data Link Connector (DLC). This connector is located to the right of the steering column and attached to the lower portion of the instrument panel. The rolls test terminal is spliced to the WSS circuit. The vehicle is then driven on a set of rollers and the WSS output is monitored for proper operation. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Antilock Brakes / Traction Control Systems > Wheel Speed Sensor > Component Information > Service and Repair > Wheel Speed Sensor Replacement Wheel Speed Sensor: Service and Repair Wheel Speed Sensor Replacement Front CAUTION: Special bolts are used to attach the front sensor.

The procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to remove any air remaining in the system. 1. Perform base brake bleeding. 2. Connect scan tool to the Data Link Connector. 3. Select ANTILOCK BRAKES, followed by MISCELLANEOUS, then BLEED BRAKES. Follow the instructions displayed. When scan tool displays TEST COMPLETE, disconnect scan tool and proceed. 4. Perform base brake bleeding a second time. 5. Top off master cylinder fluid level and verify proper brake operation before moving vehicle. W/ Rear Wheel Antilock Brakes Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only. Use fresh, clean fluid from a sealed container at all times. Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into small bubbles that are distributed throughout the hydraulic system. This will make additional bleeding operations necessary. Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow additional air to be drawn into the system. Check the cylinder fluid level frequently and add fluid as needed. Bleed only one brake component at a time in the following sequence: Master Cylinder - Combination Valve - Rear Antilock Valve - Left Rear Wheel - Right Rear Wheel - Right Front Wheel - Left Front Wheel MANUAL BLEEDING 1. Remove reservoir filler caps and fill reservoir. 2. If calipers, or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws. Then close each bleed screw as fluid starts to drip from it. Top off master cylinder reservoir once more before proceeding. Bleed Hose Setup Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures > Page 4051 3. Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially filled with brake fluid. Be sure end of bleed hose is immersed in fluid. 4. Open up bleeder, then have a helper press down the brake pedal. Once the pedal is down close the bleeder. Repeat bleeding until fluid stream is clear and free of bubbles. Then move to the next wheel. PRESSURE BLEEDING Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the tank manufacturers pressure recommendations. Generally, a tank pressure of 15-20 psi is sufficient for bleeding. Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding. Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to leakage, or drawing air back into the system. Use the adapter provided with the equipment or Adapter 6921. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures > Page 4052 Brake Bleeding: Service and Repair Base Brake System Bleeding Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only.

Light surface rust and scale can be removed with a lathe equipped with dual sanding discs. The rotor surfaces can be restored by machining in a disc brake lathe if surface scoring and wear are light. Replace the rotor under the following conditions: severely scored - tapered - hard spots - cracked - below minimum thickness ROTOR MINIMUM THICKNESS Measure rotor thickness at the center of the brake shoe contact surface. Replace the rotor if worn below minimum thickness, or if machining would reduce thickness below the allowable minimum. Rotor minimum thickness is usually specified on the rotor hub. The specification is either stamped or cast into the hub surface. ROTOR RUNOUT Checking Rotor Runout And Thickness Variation Check rotor lateral runout with dial indicator C-3339. Excessive lateral runout will cause brake pedal pulsation and rapid, uneven wear of the brake shoes. Position the dial indicator plunger approximately 25.4 mm (1 inch) inward from the rotor edge. Maximum allowable rotor runout is 0.102 mm (0.004 inch). ROTOR THICKNESS VARIATION Variations in rotor thickness will cause pedal pulsation, noise and shudder. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component Information > Specifications > Page 4088 Measuring Rotor Thickness Measure rotor thickness at 6 to 12 points around the rotor face.

Generally, a drum can be machined to a maximum of 1.52 mm (0.060 inch) oversize. Always replace the drum if machining would cause drum diameter to exceed the size limit indicated on the drum. BRAKE DRUM RUNOUT Measure drum diameter and runout with an accurate gauge. The most accurate method of measurement involves mounting the drum in a brake lathe and checking variation and runout with a dial indicator. Variations in drum diameter should not exceed 0.076 mm (0.003 inch). Drum runout should not exceed 0.20 mm (0.008 inch) out of round. Machine the drum if runout or variation exceed these values. Replace the drum if machining causes the drum to exceed the maximum allowable diameter. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Drum Brake System > Brake Drum > Component Information > Specifications > Page 4101 Brake Drum: Service and Repair MACHINING The brake drums can be machined on a drum lathe when necessary. Initial machining cuts should be limited to 0.12-0.20 mm (0.005-0.008 inch) at a time as heavier feed rates can produce taper and surface variation. Final finish cuts of 0.025-0.038 mm (0.001-0.0015 inch) are recommended and will generally provide the best surface finish. Be sure the drum is securely mounted in the lathe before machining operations. A damper strap should always be used around the drum to reduce vibration and avoid chatter marks. The maximum allowable diameter of the drum braking surface is stamped or cast into the drum outer edge. CAUTION: Replace the drum if machining will cause the drum to exceed the maximum allowable diameter. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Drum Brake System > Brake Shoe > Component Information > Specifications Brake Shoe: Specifications As a general rule, riveted brake shoes should be replaced when worn to within 0.78 mm (1/32 inch) of the rivet heads.

The procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to remove any air remaining in the system. 1. Perform base brake bleeding. 2. Connect scan tool to the Data Link Connector. 3. Select ANTILOCK BRAKES, followed by MISCELLANEOUS, then BLEED BRAKES. Follow the instructions displayed. When scan tool displays TEST COMPLETE, disconnect scan tool and proceed. 4. Perform base brake bleeding a second time. 5. Top off master cylinder fluid level and verify proper brake operation before moving vehicle. W/ Rear Wheel Antilock Brakes Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only. Use fresh, clean fluid from a sealed container at all times. Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into small bubbles that are distributed throughout the hydraulic system. This will make additional bleeding operations necessary. Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow additional air to be drawn into the system. Check the cylinder fluid level frequently and add fluid as needed. Bleed only one brake component at a time in the following sequence: Master Cylinder - Combination Valve - Rear Antilock Valve - Left Rear Wheel - Right Rear Wheel - Right Front Wheel - Left Front Wheel MANUAL BLEEDING 1. Remove reservoir filler caps and fill reservoir. 2. If calipers, or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws. Then close each bleed screw as fluid starts to drip from it. Top off master cylinder reservoir once more before proceeding.

Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially filled with brake fluid. Be sure end of bleed hose is immersed in fluid. 4. Open up bleeder, then have a helper press down the brake pedal. Once the pedal is down close the bleeder. Repeat bleeding until fluid stream is clear and free of bubbles. Then move to the next wheel. PRESSURE BLEEDING Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the tank manufacturers pressure recommendations. Generally, a tank pressure of 15-20 psi is sufficient for bleeding. Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding. Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to leakage, or drawing air back into the system. Use the adapter provided with the equipment or Adapter 6921. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Bleeding > System Information > Service and Repair > Antilock Brake System Bleeding Procedures > Page 4121 Brake Bleeding: Service and Repair Base Brake System Bleeding Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only.

MODELS: 1986 - 1999 (AN) Dakota 1998 - 1999 (DN) Durango DISCUSSION: A Brake Knuckle Thread Repair Kit has been developed to repair stripped threads on the front brake caliper mounting attachment making it no longer necessary to replace the front steering knuckle/brake caliper mounting adapter when encountering stripped threads. The following information provides the repair procedure for using the Brake Knuckle Thread Repair Kit. DIAGNOSIS: 1. Place the vehicle on an appropriate hoist. 2. Remove the front tire/wheel assembly. 3. Remove the brake caliper housing assembly by loosening the mounting bolts. NOTE: IF HIGH TORQUE IS ENCOUNTERED DURING THE MOUNTING BOLT REMOVAL, IT IS LIKELY THAT THREAD DAMAGE WILL OCCUR OR HAS OCCURRED. 4. Remove the caliper housing assembly and hang the housing on the frame of the vehicle using an appropriate wire hanger. NOTE: DO NOT ALLOW THE CALIPER HOUSING TO HANG BY ITSELF FROM THE BRAKE HOSE AS DAMAGE TO THE HOSE MAY RESULT. 5. If the vehicle has a bolt-on brake caliper mounting adapter, remove the adapter. If the brake caliper mounts directly to the steering knuckle, remove retainers on the wheel studs and remove the rotor. 6. Inspect the mounting bolts and knuckle threads for damage. If either is damaged, it is likely that damage to the other has occurred as well. If damage has occurred to the threads in the form of knicks, thread pulling, or cross-threading, perform the Repair Procedure.

As hydraulic brake fluid absorbs moisture, it effects the function of the vehicles hydraulic brake system. For this reason, the vehicle's hydraulic brake fluid should be drained and replaced using fresh clean hydraulic brake fluid every two years. When replacing hydraulic brake fluid, use only Mopar brake fluid or an equivalent from a sealed container. Brake fluid must conform to DOT 3 specifications. BRAKE FLUID CONTAMINATION Indications of fluid contamination are swollen or deteriorated rubber parts. Swelling indicates the presence of petroleum in the brake fluid. To test for contamination, put a small amount of drained brake fluid in clear glass jar. If the fluid separates into layers, there is mineral oil or other fluid contamination of the brake fluid. If the brake fluid is contaminated, drain and thoroughly flush the brake system. Replace all the rubber parts or components containing rubber coming into contact with the brake fluid. This includes the master cylinder, proportioning valves, caliper seals, wheel cylinder seals, ABS hydraulic control unit (HCU), and all hydraulic fluid hoses. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Fluid > Component Information > Specifications > Page 4140 Brake Fluid: Service and Repair BRAKE FLUID LEVEL Always clean the master cylinder reservoir and caps before checking fluid level. If not cleaned, dirt could enter the fluid. Brake Fluid Level Inspection The fluid fill level is indicated on the side of the master cylinder reservoir. The correct fluid level is to the FULL indicator on the side of the reservoir. If necessary, add fluid to the proper level. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Fluid Pressure Sensor/Switch > Component Information > Diagrams Connector Pin Identification Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Fluid Pressure Sensor/Switch > Component Information > Diagrams > Page 4144 Brake Fluid Pressure Sensor/Switch: Testing and Inspection PRESSURE DIFFERENTIAL SWITCH 1.

NOTE: Safety Recall No.870 and 892 combine the axle vent hose clip with another repair. Dealers should verify which recall the vehicle is involved in prior to completing the service procedure. ^ Safety Recall No.870 applies to 1997-2000 model year trucks equipped with a 2.5L engine and involves the axle vent hose clip and a power steering hose bracket. ^ Safety Recall No.892 applies to 1997 model year club cab (131" W.B.) trucks and involves the axle vent hose clip and a rear fuel tube isolator. IMPORTANT: Some of the involved vehicles may be in dealer new vehicle inventory. Federal law requires you to stop sale and complete this recall service on these vehicles before retail delivery. Dealers should also consider this requirement to apply to used vehicle inventory and should perform this recall on vehicles in for service. Involved vehicles can be determined by using the DIAL VIP System. Subject The rear brake hose on about 309,000 of the above vehicles may contact the rear axle vent hose. Prolonged brake hose contact may cause the hose to rub through and leak, resulting in a partial brake system loss and increased stopping distance. The increased stopping distance can cause an accident without warning. Repair The rear brake hose must be inspected for evidence of contact and/or wear. The rear axle vent hose must also be shortened and repositioned. Brake hoses that have ribs worn smooth from contact with the vent hose must be replaced. Alternate Transportation If inspection determines that brake hose replacement is required and the vehicle must be held overnight, dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle.

Double walled steel tubing is used to connect the master cylinder to the major hydraulic braking components and then to he flexible rubber hoses. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Hose/Line > Component Information > Technical Service Bulletins > Page 4180 Brake Hose/Line: Testing and Inspection Flexible rubber hose is used at both front brakes and at the rear axle junction block. Inspect the hoses whenever the brake system is serviced, at every engine oil change, or whenever the vehicle is in for service. Inspect the hoses for surface cracking, scuffing, or worn spots. Replace any brake hose immediately if the fabric casing of the hose is exposed due to cracks or abrasions. Also check brake hose installation. Faulty installation can result in kinked, twisted hoses, or contact with the wheels and tires or other chassis components. All of these conditions can lead to scuffing, cracking and eventual failure. The steel brake lines should be inspected periodically for evidence of corrosion, twists, kinks, leaks, or other damage. Heavily corroded lines will eventually rust through causing leaks. In any case, corroded or damaged brake lines should be replaced. Factory replacement brake lines and hoses are recommended to ensure quality, correct length and superior fatigue life. Care should be taken to make sure that brake line and hose mating surfaces are clean and free from nicks and burrs. Also remember that right and left brake hoses are not interchangeable. Use new copper seal washers at all caliper connections. Be sure brake line connections are properly made (not cross-threaded) and tightened to recommended torque. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Hose/Line > Component Information > Technical Service Bulletins > Page 4181 Brake Hose/Line: Service and Repair A pre-formed metal brake tube is recommended and preferred for all repairs. However, double-wall steel tube can be used for emergency repair when factory replacement parts are not readily available. Inverted Flare And ISO Flare Special bending tools are needed to avoid kinking or twisting of metal brake tubes. Special flaring tools are needed to make a double inverted flare or ISO flare. DOUBLE INVERTED FLARING 1. Cut off damaged tube with Tubing Cutter. 2. Ream cut edges of tubing to ensure proper flare. 3. Install replacement tube nut on the tube. 4. Insert tube in flaring tool. 5. Place gauge form over the end of the tube. 6. Push tubing through flaring tool jaws until tube contacts recessed notch in gauge that matches tube diameter. 7. Tighten the tool bar on the tube. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Hose/Line > Component Information > Technical Service Bulletins > Page 4182 Cutting And Flaring Of Brake Fluid Tubing 8.

The valve is not repairable and must be replaced as an assembly if diagnosis indicates this is necessary. PRESSURE DIFFERENTIAL VALVE The pressure differential switch is connected to the brake warning light. The switch is actuated by movement of the switch valve. The switch monitors fluid pressure in the separate front/rear brake hydraulic circuits. A decrease or loss of fluid pressure in either hydraulic circuit will cause the switch valve to shuttle to the low pressure side. Movement of the valve pushes the switch plunger upward. This action closes the switch internal contacts completing the electrical circuit to the red warning light. The switch valve will remain in an actuated position until repairs to the brake system are made. PROPORTIONING VALVE The proportioning valve is used to balance front rear brake action at high decelerations. The valve allows normal fluid flow during moderate braking. The valve only controls fluid flow during high decelerations brake stops. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Proportioning/Combination Valve > Component Information > Description and Operation > Page 4186 Brake Proportioning/Combination Valve: Service and Repair REMOVAL 1.

The pump, motor, and accumulators are combined into an assembly attached to the valve body. The accumulators store the extra fluid which had to be dumped from the brakes. This is done to prevent the wheels from locking up. The pump provides the fluid volume needed and is operated by a DC type motor. The motor is controlled by the Controller Antilock Brakes (CAB). The valve body contains the solenoid valves. The valves modulate brake pressure during antilock braking and are controlled by the CAB. The HCU provides three channel pressure control to the front and rear brakes. One channel controls the rear wheel brakes in tandem. The two remaining channels control the front wheel brakes individually. During antilock braking, the solenoid valves are opened and closed as needed. The valves are not static. They are cycled rapidly and continuously to modulate pressure and control wheel slip and deceleration. During normal braking, the HCU solenoid valves and pump are not activated. The master cylinder and power booster operate the same as a vehicle without an ABS brake system. During antilock braking, solenoid valve pressure modulation occurs in three stages, pressure decrease, pressure hold, and pressure increase. The valves are all contained in the valve body portion of the HCU. PRESSURE DECREASE The inlet valve is closed and the outlet valve is opened during the pressure decrease cycle. A pressure decrease cycle is initiated when speed sensor signals indicate high wheel slip at one or more wheels. At this point, the CAB closes the inlet to prevent the driver from further increasing the brake pressure and locking the brakes. The CAB then opens the outlet valve, which also opens the return circuit to the accumulators. Fluid pressure is allowed to bleed off (decrease) as needed to prevent wheel lock. Once the period of high wheel slip has ended, the CAB closes the outlet valve and begins a pressure increase or hold cycle as needed. PRESSURE HOLD Both solenoid valves are closed in the pressure hold cycle. Fluid apply pressure in the control channel is maintained at a constant rate. The CAB maintains the hold cycle until sensor inputs indicate a pressure change is necessary. PRESSURE INCREASE The inlet valve is open and the outlet valve is closed during the pressure increase cycle. The pressure increase cycle is used to counteract unequal wheel speeds. This cycle controls re-application of fluid apply pressure due to changing road surfaces or wheel speed. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Hydraulic Control Assembly Antilock Brakes > Component Information > Description and Operation > With Four Wheel Antilock Brakes > Page 4193 Hydraulic Control Assembly - Antilock Brakes: Description and Operation With Rear Wheel Antilock Brakes RWAL Cab The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics. - Monitor the RWAL brake system for proper operation. - Control the RWAL valve solenoids. NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB. SYSTEM SELF-TEST When the ignition switch is turned-on the microprocessor RAM and ROM are tested. If an error occurs during the test, a DTC will be set into the RAM memory. However it is possible the DTC will not be stored in memory if the error has occurred in the RAM module were the DTC's are stored. Also it is possible a DTC may not be stored if the error has occurred in the ROM which signals the RAM to store the DTC. CAB INPUTS The CAB continuously monitors the speed of the differential ring gear by monitoring signals generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency when it recognizes the ring gear decelerating too rapidly. The CAB monitors the following inputs to determine when a wheel locking tendency may exists: Rear Wheel Speed Sensor - Brake Lamp Switch - Brake Warning Lamp Switch - Reset Switch - 4WD Switch (If equipped) CAB OUTPUTS The CAB controls the following outputs for antilock braking and brake warning information: RWAL Valve - ABS Warning Lamp - Brake Warning Lamp VALVE REAR WHEEL ANTILOCK BRAKES If the CAB senses that rear wheel speed deceleration is excessive, it will energize an isolation solenoid by providing battery voltage to the solenoid. This prevents a further increase of driver induced brake pressure to the rear wheels. If this initial action is not enough to prevent rear wheel lock-up, the CAB will momentarily energize a dump solenoid (the CAB energizes the dump solenoid by providing battery voltage to the solenoid). This opens the dump valve to vent a small amount of isolated rear brake pressure to an accumulator. The action of fluid moving to the accumulator reduces the isolated brake pressure at the wheel cylinders. The dump (pressure venting) cycle is limited to very short time periods (milliseconds). The CAB will pulse the dump valve until rear wheel deceleration matches the desired slip rate programmed into the CAB. The system will switch to normal braking once wheel locking tendencies are no longer present. A predetermined maximum number of consecutive dump cycles can be performed during any RWAL stop. If excessive dump cycles occur, a DTC will be set and stored in the CAB memory. If during a RWAL stop, the driver releases the brake pedal, the reset switch contacts will open. This signal to the CAB is an indication that pressure has equalized across the RWAL valve. The CAB will then reset the dump cycle counter in anticipation of the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Hydraulic Control Assembly Antilock Brakes > Component Information > Description and Operation > With Four Wheel Antilock Brakes > Page 4194 next RWAL stop. Additionally, any fluid stored in the accumulator will force its way past the dump valve, back into the hydraulic circuit and return to the master cylinder. A fuse internal to the CAB, provides a fail-safe device which prevents unwanted control over the isolation and dump solenoids. The fuse is in series with the isolation and dump solenoids output circuits. If the internal fuse is open, the CAB cannot provide voltage to energize either solenoid and RWAL stops are prevented. If the fuse is open, the braking system will operate normally but without antilock control over rear brake pressure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Hydraulic Control Assembly Antilock Brakes > Component Information > Service and Repair > Front Antilock Valve Replacement Hydraulic Control Assembly - Antilock Brakes: Service and Repair Front Antilock Valve Replacement NOTE: If the antilock control assembly needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new Controller Antilock Brakes (CAB).

The cylinder body containing the primary and secondary pistons is made of aluminum. The removable fluid reservoir is made of nylon reinforced with glass fiber. The reservoir is the only serviceable component. The fluid compartments of the nylon reservoir are interconnected to permit fluid level equalization. However, the equalization feature does not affect circuit separation in the event of a front or rear brake malfunction. The reservoir compartments will retain enough fluid to operate the functioning hydraulic circuit. Care must be exercised when removing/installing the master cylinder connecting lines. The threads in the cylinder fluid ports can be damaged if care is not exercised. Start all brake line fittings by hand to avoid cross threading. The cylinder reservoir can be replaced when necessary. However, the aluminum body section of the master cylinder is not a repairable component. NOTE: If diagnosis indicates that an internal malfunction has occurred, the aluminum body section must be replaced as an assembly. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Hydraulic System, Brakes > Brake Master Cylinder > Component Information > Service and Repair > Master Cylinder Bleeding Brake Master Cylinder: Service and Repair Master Cylinder Bleeding A new master cylinder should be bled before installation on the vehicle.

The modulated hydraulic pressure is used to prevent wheel lock up during braking. The CAB also provides a vehicle speed signal (VSS) to the powertrain control module. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 4252 Electronic Brake Control Module: Description and Operation With Four Wheel Antilock Brakes CAB/HCU The Controller Antilock Brakes (CAB) is mounted on the top of the hydraulic control unit. The CAB operates the ABS system and is separate from other vehicle electrical circuits. CAB voltage source is through the ignition switch in the RUN position. The CAB contains dual microprocessors. A logic block in each microprocessor receives identical sensor signals. These signals are processed and compared simultaneously. The CAB contains a self check program that illuminates the ABS warning light when a system fault is detected. Faults are stored in a diagnostic program memory and are accessible with the DRB scan tool. ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50 times. Stored faults are not erased if the battery is disconnected. NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 4253 Electronic Brake Control Module: Description and Operation With Rear Wheel Antilock Brakes RWAL Cab The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics. - Monitor the RWAL brake system for proper operation. - Control the RWAL valve solenoids. NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB. SYSTEM SELF-TEST When the ignition switch is turned-on the microprocessor RAM and ROM are tested. If an error occurs during the test, a DTC will be set into the RAM memory. However it is possible the DTC will not be stored in memory if the error has occurred in the RAM module were the DTC's are stored. Also it is possible a DTC may not be stored if the error has occurred in the ROM which signals the RAM to store the DTC. CAB INPUTS The CAB continuously monitors the speed of the differential ring gear by monitoring signals generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency when it recognizes the ring gear decelerating too rapidly. The CAB monitors the following inputs to determine when a wheel locking tendency may exists: Rear Wheel Speed Sensor - Brake Lamp Switch - Brake Warning Lamp Switch - Reset Switch - 4WD Switch (If equipped) CAB OUTPUTS The CAB controls the following outputs for antilock braking and brake warning information: RWAL Valve - ABS Warning Lamp - Brake Warning Lamp VALVE REAR WHEEL ANTILOCK BRAKES If the CAB senses that rear wheel speed deceleration is excessive, it will energize an isolation solenoid by providing battery voltage to the solenoid. This prevents a further increase of driver induced brake pressure to the rear wheels. If this initial action is not enough to prevent rear wheel lock-up, the CAB will momentarily energize a dump solenoid (the CAB energizes the dump solenoid by providing battery voltage to the solenoid). This opens the dump valve to vent a small amount of isolated rear brake pressure to an accumulator. The action of fluid moving to the accumulator reduces the isolated brake pressure at the wheel cylinders. The dump (pressure venting) cycle is limited to very short time periods (milliseconds). The CAB will pulse the dump valve until rear wheel deceleration matches the desired slip rate programmed into the CAB. The system will switch to normal braking once wheel locking tendencies are no longer present. A predetermined maximum number of consecutive dump cycles can be performed during any RWAL stop. If excessive dump cycles occur, a DTC will be set and stored in the CAB memory. If during a RWAL stop, the driver releases the brake pedal, the reset switch contacts will open. This signal to the CAB is an indication that pressure has equalized across the RWAL valve. The CAB will then reset the dump cycle counter in anticipation of the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Description and Operation > Controller Antilock Brake (CAB) > Page 4254 next RWAL stop. Additionally, any fluid stored in the accumulator will force its way past the dump valve, back into the hydraulic circuit and return to the master cylinder. A fuse internal to the CAB, provides a fail-safe device which prevents unwanted control over the isolation and dump solenoids. The fuse is in series with the isolation and dump solenoids output circuits. If the internal fuse is open, the CAB cannot provide voltage to energize either solenoid and RWAL stops are prevented. If the fuse is open, the braking system will operate normally but without antilock control over rear brake pressure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Relays and Modules - Brakes and Traction Control > Electronic Brake Control Module > Component Information > Service and Repair > Four Wheel Antilock Brake System Electronic Brake Control Module: Service and Repair Four Wheel Antilock Brake System NOTE: If the Controller Antilock Brakes (CAB) needs to be replaced, the rear axle type and tire revolutions per mile must be programmed into the new CAB.

A sensor is mounted to each front steering knuckles. The third sensor is mounted on top of the rear axle differential housing. The sensor is a magnet coil that is mounted over a tone wheel front/exciter ring rear with an air gap between them. The sensors measure the wheel speed by monitoring the rotation of the tone wheels front/exciter ring rear. As the teeth of the tone wheels front/exciter ring rear move through the magnetic field of the sensor an AC voltage is generated. This signal frequency increases or decreases proportionally to the speed of the wheel. The CAB monitors these signals for changes in wheel deceleration. If the CAB detects a sudden wheel or wheels deceleration within a predetermined amount the CAB will activate the ABS system. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Sensors and Switches - Brakes and Traction Control > Wheel Speed Sensor > Component Information > Description and Operation > Four Wheel Antilock Brakes > Page 4279 Wheel Speed Sensor: Description and Operation Rear Wheel Antilock Brakes Rear Wheel Speed Sensor Location The rear Wheel Speed Sensor (WSS) is mounted in the rear differential housing. The WSS consists of a magnet surrounded by windings from a single strand of wire. The sensor sends a small AC signal to the CAB. This signal is generated by magnetic induction. The magnetic induction is created when a toothed sensor ring (exciter ring or tone wheel) passes the stationary magnetic WSS. Exciter Ring Location The exciter ring is press fitted onto the differential carrier next to the final drive ring gear. For replacement procedure of the exciter ring, refer to Transmission and Drivetrain. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Sensors and Switches - Brakes and Traction Control > Wheel Speed Sensor > Component Information > Description and Operation > Four Wheel Antilock Brakes > Page 4280 Operation Of The Wheel Speed Sensor When the ring gear is rotated, the exciter ring passes the tip of the WSS. As the exciter ring passes the tip of the WSS, the magnetic lines of force of the sensor are cut, causing the magnetic field to be moved across the sensor's windings. This, in turn causes current to flow through the WSS circuit. Every time a tooth of the exciter ring passes the tip of the WSS, an AC signal is generated. Each AC signal (positive to negative signal or sinewave) is interpreted by the CAB. It then compares the frequency of the sinewave to a time value to calculate vehicle speed. The CAB continues to monitor the frequency to determine a deceleration rate that would indicate a possible wheel-locking tendency. The signal strength of any magnetic induction sensor is directly affected by: Magnetic field strength; the stronger the magnetic field, the stronger the signal - Number of windings in the sensor; more windings provide a stronger signal - Exciter ring speed; the faster the exciter ring rotates, the stronger the signal will be - Distance between the exciter ring teeth and WSS; the closer the WSS is to the exciter ring, the stronger the signal will be The rear WSS is not adjustable. A clearance specification has been established for manufacturing tolerances. If the clearance is not within these specifications, then either the WSS or other components may be damaged. The clearance between the WSS and the exciter ring is 0.005-0.050 inch. Data Link Connector - Typical The assembly plant performs a "Rolls Test" on every vehicle that leaves the assembly plant. One of the tests performed is a test of the WSS. To properly test the sensor, the assembly plant connects test equipment to the Data Link Connector (DLC). This connector is located to the right of the steering column and attached to the lower portion of the instrument panel. The rolls test terminal is spliced to the WSS circuit. The vehicle is then driven on a set of rollers and the WSS output is monitored for proper operation. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Brakes and Traction Control > Sensors and Switches - Brakes and Traction Control > Wheel Speed Sensor > Component Information > Service and Repair > Wheel Speed Sensor Replacement Wheel Speed Sensor: Service and Repair Wheel Speed Sensor Replacement Front CAUTION: Special bolts are used to attach the front sensor.

The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. See the fuse and relay layout label affixed to the inside surface of the PDC cover for starter relay identification and location. The starter relay is a International Standards Organization (ISO) micro-relay. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. The ISO micro-relay terminal functions are the same as a conventional ISO relay However, the ISO micro-relay terminal pattern (or footprint) is different, the current capacity is lower, and the physical dimensions are smaller than those of the conventional ISO relay. The starter relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one movable) electrical contacts. The movable (common feed) relay contact is held against one of the fixed contacts (normally closed) by spring pressure. When the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Relays and Modules - Starting and Charging > Starter Relay > Component Information > Locations > Page 4319 Starter Relay: Testing and Inspection Starter Relay The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. Refer to the fuse and relay layout label affixed to the underside of the PDC cover for starter relay identification and location. 1. Remove the starter relay from the PDC. Refer to Starter Relay Replacement for the procedures. 2. A relay in the de-energized position should have continuity between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go to Step 3. If not OK, replace the faulty relay 3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to Step 4. If not OK, replace the faulty relay 4. Connect a battery to terminals 85 and 86. There should now be continuity between terminals 30 and 87, and no continuity between terminals 87A and 30. If OK, perform the Relay Circuit Test that follows. If not OK, replace the faulty relay. Relay Circuit Test 1. The relay common feed terminal cavity (30) is connected to battery voltage and should be hot at all times. If OK, go to Step 2. If not OK, repair the open circuit to the fuse in the PDC as required. 2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized position, but is not used for this application. Go to Step 3. 3. The relay normally open terminal (87) is connected to the common feed terminal (30) in the energized position. This terminal supplies battery voltage to the starter solenoid field coils. There should be continuity between the cavity for relay terminal 87 and the starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair the open circuit to the starter solenoid as required. 4. The coil battery terminal (86) is connected to the electromagnet in the relay. It is energized when the ignition switch is held in the Start position. On vehicles with a manual transmission, the clutch pedal must be fully depressed for this test. Check for battery voltage at the cavity for relay terminal 86 with the ignition switch in the Start position, and no voltage when the ignition switch is released to the On position. If OK, go to Step 5. If not OK with an automatic transmission, check for an open or short circuit to the ignition switch and repair, if required. If the circuit to the ignition switch is OK, refer to Ignition Switch and Key Lock Cylinder Diagnosis. If not OK with a manual transmission, check the circuit between the relay and the clutch pedal position switch for an open or a short. If the circuit is OK, refer to Clutch Pedal Position Switch Diagnosis. 5. The coil ground terminal (85) is connected to the electromagnet in the relay. On vehicles with a manual transmission, it is grounded at all times. On vehicles with an automatic transmission, it is grounded through the park/neutral position switch only when the gearshift selector lever is in the Park or Neutral positions. Check for continuity to ground at the cavity for relay terminal 85. If not OK with a manual transmission, repair the circuit to ground as required. If not OK with an automatic transmission, check for an open or short circuit to the park/neutral position switch and repair, if required. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Relays and Modules - Starting and Charging > Starter Relay > Component Information > Locations > Page 4320 Starter Relay: Service and Repair REMOVAL 1.

The starter motor is mounted with one screw, a stud and a nut to the manual transmission clutch housing or automatic transmission torque converter housing and is located on the left side of the engine. Each of these starter motors incorporates several of the same features to create a reliable, efficient, compact, lightweight and powerful unit. The electric motors of both starters have four brushes contacting the motor commutator. The starter motors feature four electromagnetic field coils wound around four pole shoes. The starter motor is rated at 1.4 kilowatts (about 1.9 horsepower) output at 12 volts. These starter motors are serviced only as a unit with their starter solenoids, and cannot be repaired. If either component is faulty or damaged, the entire starter motor and starter solenoid unit must be replaced. OPERATION These starter motors are equipped with a gear reduction (intermediate transmission) system. The gear reduction system consists of a gear that is integral to the output end of the electric motor armature shaft that is in continual engagement with a larger gear that is splined to the input end of the starter pinion gear shaft. This feature makes it possible to reduce the dimensions of the starter. At the same time, it allows higher armature rotational speed and delivers increased torque through the starter pinion gear to the starter ring gear. The starter motors for all engines are activated by an integral heavy duty starter solenoid switch mounted to the overrunning clutch housing. This electromechanical switch connects and disconnects the feed of battery voltage to the starter motor and actuates a shift fork that engages and disengages the starter pinion gear with the starter ring gear. These starter motors use an overrunning clutch and starter pinion gear unit to engage and drive a starter ring gear that is integral to the flywheel (manual transmission), torque converter or torque converter drive plate (automatic transmission) mounted on the rear crankshaft flange. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Starting System > Starter Motor > Component Information > Specifications > Page 4363 Starter Motor: Testing and Inspection Correct starter motor operation can be confirmed by performing the following free running bench test.

OPERATION The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one movable) electrical contacts. The movable (common feed) relay contact is held against one of the fixed contacts (normally closed) by spring pressure. When the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Starting System > Starter Relay > Component Information > Locations > Page 4372 Starter Relay: Testing and Inspection Starter Relay The starter relay is located in the Power Distribution Center (PDC), in the engine compartment. Refer to the fuse and relay layout label affixed to the underside of the PDC cover for starter relay identification and location. 1. Remove the starter relay from the PDC. Refer to Starter Relay Replacement for the procedures. 2. A relay in the de-energized position should have continuity between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go to Step 3. If not OK, replace the faulty relay 3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to Step 4. If not OK, replace the faulty relay 4. Connect a battery to terminals 85 and 86. There should now be continuity between terminals 30 and 87, and no continuity between terminals 87A and 30. If OK, perform the Relay Circuit Test that follows. If not OK, replace the faulty relay. Relay Circuit Test 1. The relay common feed terminal cavity (30) is connected to battery voltage and should be hot at all times. If OK, go to Step 2. If not OK, repair the open circuit to the fuse in the PDC as required. 2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized position, but is not used for this application. Go to Step 3. 3. The relay normally open terminal (87) is connected to the common feed terminal (30) in the energized position. This terminal supplies battery voltage to the starter solenoid field coils. There should be continuity between the cavity for relay terminal 87 and the starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair the open circuit to the starter solenoid as required. 4. The coil battery terminal (86) is connected to the electromagnet in the relay. It is energized when the ignition switch is held in the Start position. On vehicles with a manual transmission, the clutch pedal must be fully depressed for this test. Check for battery voltage at the cavity for relay terminal 86 with the ignition switch in the Start position, and no voltage when the ignition switch is released to the On position. If OK, go to Step 5. If not OK with an automatic transmission, check for an open or short circuit to the ignition switch and repair, if required. If the circuit to the ignition switch is OK, refer to Ignition Switch and Key Lock Cylinder Diagnosis. If not OK with a manual transmission, check the circuit between the relay and the clutch pedal position switch for an open or a short. If the circuit is OK, refer to Clutch Pedal Position Switch Diagnosis. 5. The coil ground terminal (85) is connected to the electromagnet in the relay. On vehicles with a manual transmission, it is grounded at all times. On vehicles with an automatic transmission, it is grounded through the park/neutral position switch only when the gearshift selector lever is in the Park or Neutral positions. Check for continuity to ground at the cavity for relay terminal 85. If not OK with a manual transmission, repair the circuit to ground as required. If not OK with an automatic transmission, check for an open or short circuit to the park/neutral position switch and repair, if required. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Starting System > Starter Relay > Component Information > Locations > Page 4373 Starter Relay: Service and Repair REMOVAL 1.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4386 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4387 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4388 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4389 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4390 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4391 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4401 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4402 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Page 4403 Auxiliary Power Outlet: Service Precautions WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIR-BAG BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango 1999 (TJ) Wrangler 1999 (WJ) Grand Cherokee 1999 (XJ) Cherokee DISCUSSION: Recent quality analysis has revealed an issue with repeated repairs for the same Diagnostic Trouble Code (DTC). The DTC may be due to an overlooked open circuit used to power the component in question. In most instances, either the circuit fuse has been erroneously removed or the fuse itself has an open (blown). The component in question, and its circuit, are often protected by two fuses. It is usually the lower amperage fuse that is either missing or open. The lower amperage fuse is positioned electrically in the circuit between the component in question and either a relay (Auto Shut Down, 02 heater) or the ignition switch. The lower amperage fuse will be located either in the underhood Power Distribution Center (PDC) or in the instrument panel Junction Block. The lower amperage fuse is often missing because it was removed erroneously for use in another low current circuit. If the lower amperage fuse is open (blown), then the circuit and component in question must be checked for an electrical short. Check to make sure that the open fuse was not exchanged with another fuse or was damaged by an installed accessory. NOTE: IF AN OXYGEN SENSOR IS REPLACED, VERIFY THAT THE CIRCUIT FUSE IS GOOD. AN OXYGEN SENSOR HEATER, WHEN DAMAGED OR OVERHEATED, MAY SHORT THE CIRCUIT AND CAUSE THE FUSE TO OPEN (BLOW). The higher amperage fuse should be checked, but is not normally the cause of the DTC. The higher amperage fuse is located in the underhood PDC. It is positioned electrically in the circuit between the battery and either the relay (Auto Shut Down, 02 heater) or the ignition switch. Refer to the applicable Diagnostic Procedures Manual and/or Service Manual (Group 8) for further technical assistance. The following is a list of the components frequently replaced erroneously due to an open fuse. Included are the possible DTC(s) which would be generated as a result. 1).

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4444 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4445 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4446 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4447 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4448 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4449 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4459 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4460 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component

FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY . Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Page 4486 Fuse Block: Description and Operation JUNCTION BLOCK DESCRIPTION Junction Block An electrical Junction Block (JB) is concealed behind the left outboard end of the instrument panel cover. The molded plastic JB housing has integral mounting brackets that are secured with two screws to the left instrument panel end bracket. The left end of the instrument panel cover has a snap-fit fuse access panel that can be removed for service of the junction block fuses. A fuse puller and spare fuse holders are located on the back of the fuse access cover, as well as an adhesive-backed fuse layout label to ensure proper fuse identification. The JB combines the functions previously provided by a separate fuseblock module and relay center, serves to simplify and centralize numerous electrical components, and to distribute electrical current to many of the accessory systems in the vehicle. It also eliminates the need for numerous splice connections and serves in place of a bulkhead connector between many of the engine compartment, instrument panel, and body wire harnesses. All of the circuits entering and leaving the JB do so through up to nine wire harness connectors, which are connected to the JB. through integral connector receptacles molded into the JB housing. The JB houses up to nineteen blade-type fuses (two standard-type and seventeen mini-type), up to two blade- type automatic resetting circuit breakers, the electronic combination turn signal and hazard warning flasher, and one International Standards Organization (ISO) micro-relay Internal connection of all of the JB circuits is accomplished by an intricate combination of hard wiring and bus bars. The fuses, circuit breakers, relays and flasher are available for service replacement. The JB unit cannot be repaired and is only serviced as an assembly. If any internal circuit or if the JB housing is faulty or damaged, the entire JB unit must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Page 4487 Fuse Block: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4510 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4511 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4512 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4513 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK.

Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4525 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Diagram Information and Instructions > Page 4526 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams > Page 4527 Auxiliary Power Outlet: Service Precautions WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIR-BAG BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

MODELS: 1999 (AB) Ram Van 1999 (AN) Dakota 1999 (BR/BE) Ram Truck 1999 (DN) Durango 1999 (TJ) Wrangler 1999 (WJ) Grand Cherokee 1999 (XJ) Cherokee DISCUSSION: Recent quality analysis has revealed an issue with repeated repairs for the same Diagnostic Trouble Code (DTC). The DTC may be due to an overlooked open circuit used to power the component in question. In most instances, either the circuit fuse has been erroneously removed or the fuse itself has an open (blown). The component in question, and its circuit, are often protected by two fuses. It is usually the lower amperage fuse that is either missing or open. The lower amperage fuse is positioned electrically in the circuit between the component in question and either a relay (Auto Shut Down, 02 heater) or the ignition switch. The lower amperage fuse will be located either in the underhood Power Distribution Center (PDC) or in the instrument panel Junction Block. The lower amperage fuse is often missing because it was removed erroneously for use in another low current circuit. If the lower amperage fuse is open (blown), then the circuit and component in question must be checked for an electrical short. Check to make sure that the open fuse was not exchanged with another fuse or was damaged by an installed accessory. NOTE: IF AN OXYGEN SENSOR IS REPLACED, VERIFY THAT THE CIRCUIT FUSE IS GOOD. AN OXYGEN SENSOR HEATER, WHEN DAMAGED OR OVERHEATED, MAY SHORT THE CIRCUIT AND CAUSE THE FUSE TO OPEN (BLOW). The higher amperage fuse should be checked, but is not normally the cause of the DTC. The higher amperage fuse is located in the underhood PDC. It is positioned electrically in the circuit between the battery and either the relay (Auto Shut Down, 02 heater) or the ignition switch. Refer to the applicable Diagnostic Procedures Manual and/or Service Manual (Group 8) for further technical assistance. The following is a list of the components frequently replaced erroneously due to an open fuse. Included are the possible DTC(s) which would be generated as a result. 1).

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4568 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4569 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4570 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4571 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4572 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4573 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number. The reference number for the subsequent diagram will match a listed group shown. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4574 Connector and Terminal Replacement 1.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4583 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram Information and Instructions > Page 4584 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams

FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY . Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Page 4610 Fuse Block: Description and Operation JUNCTION BLOCK DESCRIPTION Junction Block An electrical Junction Block (JB) is concealed behind the left outboard end of the instrument panel cover. The molded plastic JB housing has integral mounting brackets that are secured with two screws to the left instrument panel end bracket. The left end of the instrument panel cover has a snap-fit fuse access panel that can be removed for service of the junction block fuses. A fuse puller and spare fuse holders are located on the back of the fuse access cover, as well as an adhesive-backed fuse layout label to ensure proper fuse identification. The JB combines the functions previously provided by a separate fuseblock module and relay center, serves to simplify and centralize numerous electrical components, and to distribute electrical current to many of the accessory systems in the vehicle. It also eliminates the need for numerous splice connections and serves in place of a bulkhead connector between many of the engine compartment, instrument panel, and body wire harnesses. All of the circuits entering and leaving the JB do so through up to nine wire harness connectors, which are connected to the JB. through integral connector receptacles molded into the JB housing. The JB houses up to nineteen blade-type fuses (two standard-type and seventeen mini-type), up to two blade- type automatic resetting circuit breakers, the electronic combination turn signal and hazard warning flasher, and one International Standards Organization (ISO) micro-relay Internal connection of all of the JB circuits is accomplished by an intricate combination of hard wiring and bus bars. The fuses, circuit breakers, relays and flasher are available for service replacement. The JB unit cannot be repaired and is only serviced as an assembly. If any internal circuit or if the JB housing is faulty or damaged, the entire JB unit must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Page 4611 Fuse Block: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The positioning is accomplished through suspension and steering linkage adjustments. An alignment is considered essential for efficient steering, good directional stability and to minimize tire wear. The most important measurements of an alignment are caster, camber and toe. CASTER is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the knuckle forward provides negative caster. Tilting the top of the knuckle rearward provides positive caster. Positive caster promotes directional stability. This angle enables the front wheels to return to a straight ahead position after turns. - CAMBER is the inward or outward tilt of the wheel relative to the center of the vehicle. Tilting the top of the wheel inward provides negative camber. Tilting the top of the wheel outward provides positive camber. Incorrect camber will cause wear on the inside or outside edge of the tire. TOE is the difference between the leading inside edges and trailing inside edges of the front tires. Wheel toe position out of specification cause's unstable steering, uneven tire wear and steering wheel off-center. The wheel toe position is the final front wheel alignment adjustment. - THRUST ANGLE is the angle of the rear axle relative to the centerline of the vehicle. Incorrect thrust angle can cause off-center steering and excessive tire wear. This angle is not adjustable, damaged component(s) must be replaced to correct the thrust angle. CAUTION: Never attempt to modify suspension or steering components by heating or bending. NOTE: Periodic lubrication of the front suspension/ steering system components may be required. Rubber bushings must never be lubricated. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Page 4638 Alignment: Testing and Inspection PRE-ALIGNMENT INSPECTION Before starting wheel alignment, the following inspection and necessary corrections must be completed. 1. Inspect tires for size, air pressure and tread wear. 2. Inspect front wheel bearings for wear. 3. Inspect front wheels for excessive radial or lateral runout and balance. 4. Inspect ball studs, linkage pivot points and steering gear for looseness, roughness or binding. 5. Inspect suspension components for wear and noise. 6. On 4x4 vehicles check suspension height. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Page 4639 Alignment: Service and Repair NOTE: 4x4 suspension height measurement must be performed before alignment. CAMBER AND CASTER ADJUSTMENT Caster & Camber Adjustment - Typical Camber and caster angle adjustments involve changing the position of the upper suspension arm pivot bar. On 4x2 vehicles Adjuster C-4576 can be used to make camber/caster adjustments. Caster Moving the rear position of the pivot bar in or out, will change the caster angle significantly and camber angle only slightly. To maintain the camber angle while adjusting caster, move the rear of the pivot bar in or out. Then move the front of the pivot bar slightly in the opposite direction. The caster angle should be adjusted to preferred specification. NOTE: For example, to increase a positive caster angle, move the rear position of the pivot bar inward (toward the engine). Move the front of pivot bar outward (away from the engine) slightly until the original camber angle is obtained. Camber Move the front of the pivot bar in or out. This will change the camber angle significantly and caster angle slightly. The camber angle should be adjusted to preferred specification. After adjustment is made tighten the pivot bar nuts to proper torque specification. TOE ADJUSTMENT The wheel toe position adjustment is the final adjustment. 1. Start the engine and turn wheels both ways before straightening the wheels. Secure the steering wheel with the front wheels in the straight-ahead position. 2. Loosen the tie rod jam nuts. NOTE: Each front wheel should be adjusted for one-half of the total toe position specification. This will ensure the steering wheel will be centered when the wheels are positioned straight-ahead. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Page 4640 Toe Adjustment 3. Adjust the wheel toe position by turning the tie rod as necessary. 4. Tighten the tie rod jam nut to 75 Nm (56 ft. lbs.). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Technical Service Bulletins > Page 4641 Adjuster Caster/Camber C-4576 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Sensors and Switches - Steering and Suspension > Sensors and Switches - Steering > Power Steering Pressure Switch > Component Information > Diagrams Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Front Steering Knuckle > Component Information > Technical Service Bulletins > Front Caliper Mounting/Steering Knuckle - Thread Repair Front Steering Knuckle: Technical Service Bulletins Front Caliper Mounting/Steering Knuckle Thread Repair NUMBER: 05-03-99 GROUP: Brakes EFFECTIVE DATE: Apr. 23, 1999 SUBJECT: Front Brake Caliper Mounting To Steering Knuckle Thread Repair OVERVIEW: This bulletin involves repair of the threads on the steering knuckle or brake caliper mounting adapter that are used to install and retain the front brake caliper housing in its correct operating location. MODELS: 1986 - 1999 (AN) Dakota 1998 - 1999 (DN) Durango DISCUSSION: A Brake Knuckle Thread Repair Kit has been developed to repair stripped threads on the front brake caliper mounting attachment making it no longer necessary to replace the front steering knuckle/brake caliper mounting adapter when encountering stripped threads. The following information provides the repair procedure for using the Brake Knuckle Thread Repair Kit. DIAGNOSIS: 1. Place the vehicle on an appropriate hoist. 2. Remove the front tire/wheel assembly. 3. Remove the brake caliper housing assembly by loosening the mounting bolts. NOTE: IF HIGH TORQUE IS ENCOUNTERED DURING THE MOUNTING BOLT REMOVAL, IT IS LIKELY THAT THREAD DAMAGE WILL OCCUR OR HAS OCCURRED. 4.

WJ/WG and ZH vehicles use unique power steering fluids. Refer to the table to identify factory fill and the approved service power steering fluid by year and model. Note that MS9602 is Red in color and MS5931 and MS9933 are Amber/Yellow in color. All three fluids will darken in color with usage and fluid color is no longer an indication of fluid condition. The part numbers for MS9602 are 05013457AA (quart) and 05013458AA (gallon). The part number for MS5931 is 04883077 (quart). The part number for MB345 is 05127381AA. MS9602 should not be mixed or used as a "topping off" fluid on systems requiring MS5931. On some past models, MS9602 should be used as the replacement fluid. On these models, if a power steering system is being serviced that results in a large fluid loss, such as a pump, hose or gear/rack replacement, the complete system should be drained and filled with MS9602. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Power Steering > Power Steering Fluid > Component Information > Technical Service Bulletins > Steering - Power Steering Fluid Usage > Page 4661 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Power Steering > Power Steering Fluid > Component Information > Technical Service Bulletins > Steering - Power Steering Fluid Usage > Page 4662 NOTE: This bulletin supersedes owner's and service manuals for the vehicles listed above that may state to use MS9933 in the power steering system, and that may state not to use automatic transmission fluid in the power steering system.

WJ/WG and ZH vehicles use unique power steering fluids. Refer to the table to identify factory fill and the approved service power steering fluid by year and model. Note that MS9602 is Red in color and MS5931 and MS9933 are Amber/Yellow in color. All three fluids will darken in color with usage and fluid color is no longer an indication of fluid condition. The part numbers for MS9602 are 05013457AA (quart) and 05013458AA (gallon). The part number for MS5931 is 04883077 (quart). The part number for MB345 is 05127381AA. MS9602 should not be mixed or used as a "topping off" fluid on systems requiring MS5931. On some past models, MS9602 should be used as the replacement fluid. On these models, if a power steering system is being serviced that results in a large fluid loss, such as a pump, hose or gear/rack replacement, the complete system should be drained and filled with MS9602. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Power Steering > Power Steering Pump > Component Information > Technical Service Bulletins > Steering - Power Steering Fluid Usage > Page 4678 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Power Steering > Power Steering Pump > Component Information > Technical Service Bulletins > Steering - Power Steering Fluid Usage > Page 4679 NOTE: This bulletin supersedes owner's and service manuals for the vehicles listed above that may state to use MS9933 in the power steering system, and that may state not to use automatic transmission fluid in the power steering system.

The PADS is equipped with a key cylinder so that the switch position can only be changed using an ignition key. When the ignition switch is in the On position and the passenger side airbag is disarmed, a Light-Emitting Diode (LED) illuminates an "Off" indicator lamp on the face plate of the switch. To actuate the PADS switch, insert the ignition key in the switch key cylinder. The PADS key cylinder is then rotated with the ignition key to its clockwise stop (the key cylinder slot will be aligned with the Off indicator lamp) to disarm the passenger side airbag. When the PADS key cylinder is rotated with the ignition key to its counterclockwise stop (the key cylinder slot will be in a vertical position), the Off indicator lamp will be extinguished and the passenger side airbag module will once again be armed. WARNING: THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG DISARM SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE PADS KEY CYLINDER. The PADS cannot be adjusted or repaired and, if faulty or damaged, the PADS unit must be replaced. Disarming Both Airbags Disconnect and isolate the battery negative cable. If the airbag has not been deployed, wait two minutes for the system capacitor to discharge before further service. Arming Both Airbags Prior to arming the system verify system operation as follows: A DRB scan tool is required for diagnosis of the airbag system. Refer to the proper Diagnostic Procedures for more information. 16-Way Data Link Connector - Typical 1. Connect the DRB scan tool to the 16-way data link wire harness connector. The connector is located on the driver side lower edge of the instrument panel, outboard of the steering column. 2. Turn the ignition switch to the On position. Exit the vehicle with the DRE. Use the latest version of the proper DRB cartridge. 3.. Using the DRB, read and record the active Diagnostic Trouble Code (DTC) data. 4. Read and record any stored DTC data. 5. Refer to the proper Diagnostic Procedures if any DTC is found in Step 3 or Step 4. 6. Erase the stored DTC data. If any problems remain, the stored DTC data will not erase. 7. With the ignition switch still in the ON position, make sure nobody is in the vehicle. 8. From outside of the vehicle (away from the airbag modules in case of an accidental deployment) turn the ignition switch to the OFF position for about ten seconds, and then back to the ON position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds, and then go out. This indicates that the airbag system is functioning normally NOTE: It the airbag indicator lamp fails to light, or lights and stays on, there is an airbag system malfunction. Refer to the proper Diagnostic Procedures to diagnose the problem. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Steering Column > Key Reminder Switch > Component Information > Diagrams Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Steering > Steering Column > Key Reminder Switch > Component Information > Diagrams > Page 4703 Key Reminder Switch: Description and Operation SYSTEM OPERATION The key-in ignition switch is integral to the ignition switch, which is mounted on the right side of the steering column.

MODELS: 1986 - 1999 (AN) Dakota 1998 - 1999 (DN) Durango DISCUSSION: A Brake Knuckle Thread Repair Kit has been developed to repair stripped threads on the front brake caliper mounting attachment making it no longer necessary to replace the front steering knuckle/brake caliper mounting adapter when encountering stripped threads. The following information provides the repair procedure for using the Brake Knuckle Thread Repair Kit. DIAGNOSIS: 1. Place the vehicle on an appropriate hoist. 2. Remove the front tire/wheel assembly. 3. Remove the brake caliper housing assembly by loosening the mounting bolts. NOTE: IF HIGH TORQUE IS ENCOUNTERED DURING THE MOUNTING BOLT REMOVAL, IT IS LIKELY THAT THREAD DAMAGE WILL OCCUR OR HAS OCCURRED. 4. Remove the caliper housing assembly and hang the housing on the frame of the vehicle using an appropriate wire hanger. NOTE: DO NOT ALLOW THE CALIPER HOUSING TO HANG BY ITSELF FROM THE BRAKE HOSE AS DAMAGE TO THE HOSE MAY RESULT. 5. If the vehicle has a bolt-on brake caliper mounting adapter, remove the adapter. If the brake caliper mounts directly to the steering knuckle, remove retainers on the wheel studs and remove the rotor. 6. Inspect the mounting bolts and knuckle threads for damage. If either is damaged, it is likely that damage to the other has occurred as well. If damage has occurred to the threads in the form of knicks, thread pulling, or cross-threading, perform the Repair Procedure.

These noises can usually be stopped by tightening the attaching nuts. If the noise persists, inspect for damaged and worn bushings, and attaching components. Repair as necessary if any of these conditions exist. A squeaking noise from the shock absorber may be caused by the hydraulic valving and may be intermittent. This condition is not repairable and the shock absorber must be replaced. The shock absorbers are not refillable or adjustable. If a malfunction occurs, the shock absorber must be replaced. To test a shock absorber, hold it in an upright position and force the piston in and out of the cylinder four or five times. The action throughout each stroke should be smooth and even. The shock absorber bushings do not require any type of lubrication. Do not attempt to stop bushing noise by lubricating them. Grease and mineral oil-base lubricants will deteriorate the bushing. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Suspension > Suspension Strut / Shock Absorber > Component Information > Service and Repair > Front Suspension Strut / Shock Absorber: Service and Repair Front REMOVAL 1.

The original tire should be repaired or replaced at the first opportunity and reinstall. Do not exceed speeds of 50 MPH. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Description and Operation Wheels: Description and Operation The rim size is on the vehicle safety certification label located on the drivers door shut face. The size of the rim is determined by the drivetrain package. Original equipment wheels/rims are designed for operation up to the specified maximum vehicle capacity. Fig. 1 All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised sections between the rim flanges and rim drop well called safety humps. Initial inflation of the tire forces the bead over these raised sections. In case of rapid loss of air pressure, the raised sections help hold the tire on the wheel. The wheel studs and nuts are designed for specific applications. All aluminum and some steel wheels have wheel stud nuts with an enlarged nose. This enlarged nose is necessary to ensure proper retention of the wheels. Do not use replacement studs or nuts with a different design or lesser quality. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Description and Operation > Page 4826 Wheels: Testing and Inspection Inspect wheels for: Excessive run out - Dents or cracks - Damaged wheel lug nut holes - Air Leaks from any area or surface of the rim NOTE: Do not attempt to repair a wheel by hammering, heating or welding. If a wheel is damaged an original equipment replacement wheel should be used. When obtaining replacement wheels, they should be equivalent in load carrying capacity. The diameter, width, offset, pilot hole and bolt circle of the wheel should be the same as the original wheel. WARNING: FAILURE TO USE EQUIVALENT REPLACEMENT WHEELS MAY ADVERSELY AFFECT THE SAFETY AND HANDLING OF THE VEHICLE. USED WHEELS ARE NOT RECOMMENDED. THE SERVICE HISTORY OF THE WHEEL MAY HAVE INCLUDED SEVERE TREATMENT OR VERY HIGH MILEAGE. THE RIM COULD FAIL WITHOUT WARNING. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheels > Component Information > Description and Operation > Page 4827 Wheels: Service and Repair WHEEL REPLACEMENT NOTES Wheels must be replaced if they have: Excessive runout - Bent or dented - Leak air through welds - Have damaged bolt holes Wheel repairs employing hammering, heating, or welding are not allowed. Original equipment wheels are available through your dealer. Replacement wheels from any other source should be equivalent in: Load carrying capacity - Diameter - Width - Offset - Mounting configuration Failure to use equivalent replacement wheels may affect the safety and handling of your vehicle. Replacement with used wheels is not recommended. Their service history may have included severe treatment. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Steering and Suspension > Wheels and Tires > Wheel Bearing > Component Information > Technical Service Bulletins > Front Hub Seals - Grease Purge Explanation Wheel Bearing: Technical Service Bulletins Front Hub Seals - Grease Purge Explanation NUMBER: 02-06-99 Rev.

The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a screw to the right side of the radiator yoke, behind the radiator grille and in front of the engine compartment. The ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be replaced. OPERATION The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal sent to it by the compass mini-trip computer module. The resistance in the sensor changes as temperature changes, changing the temperature sensor signal circuit voltage to the compass mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip computer module senses a specific voltage on the temperature sensor signal circuit, which it is programmed to correspond to a specific temperature. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Ambient Temperature Sensor / Switch HVAC > Component Information > Specifications > Page 4905 Ambient Temperature Sensor / Switch HVAC: Testing and Inspection The thermometer function is supported by the ambient temperature sensor, a wiring circuit, and a portion of the compass mini-trip computer module. If any portion of the ambient temperature sensor circuit fails, the compass/thermometer display function will self-diagnose the circuit. An "SC" (short circuit) will appear in the display in place of the temperature, when the sensor is exposed to temperatures above 110° C (230° F), or if the sensor circuit is shorted. An "OC" (open circuit) will appear in the display in place of the temperature, when the sensor is exposed to temperatures below 50° C (-58° F), or if the sensor circuit is open. The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test, and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the temperature display is inoperative or incorrect, refer to Compass Mini-Trip Computer in the Diagnosis and Testing. Sensor Test 1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the ambient temperature sensor wire harness connector. 2. Measure the resistance of the ambient temperature sensor. At -40° C (-40° F), the sensor resistance is 336 K Ohms. At 55° C (131° F), the sensor resistance is 2.488 K Ohms. The sensor resistance should read between these two values. If OK, refer to Sensor Circuit Test in the Diagnosis and Testing. If not OK, replace the faulty ambient temperature sensor. Sensor Circuit Test 1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the ambient temperature sensor wire harness connector and the overhead console wire harness connector. 2. Connect a jumper wire between the two terminals in the body half of the ambient temperature sensor wire harness connector. 3.

However, a resistor mounting plate has been designed so that the resistor can be removed through an access hole in the cowl plenum panel just below the windshield. It can be accessed by removing the cowl plenum cover/grille panel. See Blower Motor Resistor/Service and Repair for more information. The resistor has multiple resistor wires, each of which will change the resistance in the blower motor ground path to change the blower motor speed. The blower motor switch directs the ground path through the correct resistor wire to obtain the selected blower motor speed. With the blower motor switch in the lowest speed position, the ground path for the motor is applied through all of the resistor wires. Each higher speed selected with the blower motor switch applies the blower motor ground path through fewer of the resistor wires, increasing the blower motor speed. When the blower motor switch is in the highest speed position, the blower motor resistor is bypassed and the blower motor receives a direct path to ground. The blower motor resistor cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Blower Motor Resistor > Component Information > Specifications > Page 4927 Blower Motor Resistor: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIR BAGS AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

Align the rotor assembly squarely on the front compressor housing hub. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch > Component Information > Specifications > Page 4946 Rotor Installer Set 4. Thread the handle (Special Tool 6464 in Kit 6460) into the driver (Special Tool 6143 in Kit 6460). Rotor Install 5. Place the driver tool assembly into the bearing cavity on the rotor. Make certain the outer edge of the tool rests firmly on the rotor bearing inner race). 6. Tap the end of the driver while guiding the rotor to prevent binding. Tap until the rotor bottoms against the compressor front housing hub. Listen for a distinct change of sound during the tapping process, to indicate the bottoming of the rotor. 7. Install the external front rotor snap ring with snap ring pliers. The bevel side of the snap ring must be facing outward. Press the snap ring to make sure it is properly seated in the groove. CAUTION: If the snap ring is not fully seated in the groove it will vibrate out, resulting in a clutch failure and severe damage to the front housing of the compressor. 8. Install the original clutch shims on the compressor shaft. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch > Component Information > Specifications > Page 4947 Clutch Plate Install 9. Install the clutch plate. Use the shaft protector (Special Tool 6141-2 in Kit 6460) to install the clutch plate on the compressor shaft. Tap the clutch plate over the compressor shaft until it has bottomed against the clutch shims. Listen for a distinct change of sound during the tapping process, to indicate the bottoming of the clutch plate. 10. Replace the compressor shaft hex nut. Tighten the nut to 14.4 N.m (10.5 ft. lbs.). Check Clutch Air Gap 11. Check the clutch air gap with a feeler gauge. If the air gap does not meet the specification, add or subtract shims as required. The air gap specification is 0.41 to 0.79 millimeter (0.016 to 0.031 inch). If the air gap is not consistent around the circumference of the clutch, lightly pry up at the minimum variations. Lightly tap down at the points of maximum variation. NOTE: The air gap is determined by the spacer shims. When installing an original, or a new clutch assembly, try the original shims first. When installing a new clutch onto a compressor that previously did not have a clutch, use 1.0, 0.50, and 0.13 millimeter (0.040, 0.020, and 0.005 inch) shims from the clutch hardware package that is provided with the new clutch. 12. Reverse the remaining removal procedures to complete the installation. CLUTCH BREAK-IN After a new compressor clutch has been installed, cycle the compressor clutch approximately twenty times (five seconds on, then five seconds off). During this procedure, set the heater-A/C control to the recirculation mode (Max-A/C), the blower motor switch to the highest speed position, and the engine speed at 1500 to 2000 rpm. This procedure (burnishing) will seat the opposing friction surfaces and provide a higher compressor clutch torque capability. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor HVAC > Compressor Clutch Coil > Component Information > Testing and Inspection Compressor Clutch Coil: Testing and Inspection The battery must be fully-charged before performing the following tests. Refer to Battery for more information. 1. Connect an ammeter (0 to 10 ampere scale) in series with the clutch coil terminal. Use a voltmeter (0 to 20 volt scale) with clip-type leads for measuring the voltage across the battery and the compressor clutch coil. 2. With the heater-A/C mode control switch in any A/C mode, and the blower motor switch in the lowest speed position, start the engine and run it at normal idle. 3. The compressor clutch coil voltage should read within two volts of the battery voltage. If there is voltage at the clutch coil, but the reading is not within two volts of the battery voltage, test the clutch coil feed circuit for excessive voltage drop and repair as required. If there is no voltage reading at the clutch coil, use a DRB scan tool and the proper Diagnostic Procedures for testing of the compressor clutch circuit. The following components must be checked and repaired as required before you can complete testing of the clutch coil: Fuses in the junction block and the Power Distribution Center (PDC) - Heater-A/C mode control switch - Compressor clutch relay - High pressure cut-off switch - Low pressure cycling clutch switch - Powertrain Control Module (PCM). 4. The compressor clutch coil is acceptable if the current draw measured at the clutch coil is 2.0 to 3.9 amperes with the electrical system voltage at 11.5 to 12.5 volts. This should only be checked with the work area temperature at 21° C (70° F). If system voltage is more than 12.5 volts, add electrical loads by turning on electrical accessories until the system voltage drops below 12.5 volts. a. If the clutch coil current reading is four amperes or more, the coil is shorted and should be replaced. b. If the clutch coil current reading is zero, the coil is open and should be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Locations > Component Locations Compressor Clutch Relay: Component Locations 8w-10-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Locations > Component Locations > Page 4955 Power Distribution Center (PDC) The A/C relay is located in the Power Distribution Center (PDC). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Locations > Component Locations > Page 4956 Compressor Clutch Relay: Connector Locations 8w-10-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Locations > Component Locations > Page 4957 8w-10-3 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Description and Operation > A/C Compressor Clutch Relay Description Compressor Clutch Relay: Description and Operation A/C Compressor Clutch Relay Description Power Distribution Center (PDC) SYSTEM OPERATION The compressor clutch relay is a International Standards Organization (ISO) micro-relay. The terminal designations and functions are the same as a conventional ISO relay However, the micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay case dimensions are smaller than those of the conventional ISO relay. The compressor clutch relay is a electromechanical device that switches battery current to the compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the relay. The PCM responds to inputs from the heater-A/C mode control switch, the low pressure cycling clutch switch, and the high pressure cut-off switch. The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine compartment. Refer to the PDC label for relay identification and location. The compressor clutch relay cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Description and Operation > A/C Compressor Clutch Relay Description > Page 4960 Compressor Clutch Relay: Description and Operation A/C Compressor Clutch Relay-PCM Output AIR CONDITIONING (A/C) CLUTCH RELAY - PCM OUTPUT The A/C relay is located in the Power Distribution Center (PDC). The PDC is located in the engine compartment. Refer to label on PDC cover for relay location. The powertrain control module (PCM) activates the A/C compressor through the A/C clutch relay. The PCM regulates A/C compressor operation by switching the ground circuit for the A/C clutch relay on and off. When the PCM receives a request for A/C from A/C evaporator switch, it will adjust idle air control (IAC) motor position. This is done to increase idle speed. The PCM will then activate the A/C clutch through the A/C clutch relay. The PCM adjusts idle air control (IAC) stepper motor position to compensate for increased engine load from the A/C compressor. By switching the ground path for the relay on and off, the PCM is able to cycle the A/C compressor clutch. This is based on changes in engine operating conditions. If, during A/C operation, the PCM senses low idle speeds or a wide open throttle condition, it will de-energize the relay. This prevents A/C clutch engagement. The relay will remain de-energized until the idle speed increases or the wide open throttle condition exceeds 15 seconds or no longer exists. The PCM will also de-energize the relay if coolant temperature exceeds 125° C (257° F). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Description and Operation > Page 4961 Compressor Clutch Relay: Testing and Inspection Relay Test Compressor Clutch Relay The compressor clutch relay is located in the Power Distribution Center (PDC). Refer to the PDC label for relay identification and location. Remove the relay from the PDC to perform the following tests: 1. A relay in the de-energized position should have continuity between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go to Step 2. If not OK, replace the faulty relay. 2. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to Step 3. If not OK, replace the faulty relay 3. Connect a battery to terminals 85 and 86. There should now be continuity between terminals 30 and 87, and no continuity between terminals 87A and 30. if OK, see Relay Circuit Test in the Diagnosis and Testing. If not OK, replace the faulty relay. Relay Circuit Test 1. The relay common feed terminal cavity (30) is connected to fused battery feed. There should be battery voltage at the cavity for relay terminal 30 at all times. If OK, go to Step 2. If not OK, repair the open circuit to the fuse in the PDC as required. 2. The relay normally closed terminal (87A) is not used in this application. Go to Step 3. 3. The relay normally open terminal cavity (87) is connected to the compressor clutch coil. There should be continuity between this cavity and the A/C compressor clutch relay output circuit cavity of the compressor clutch coil wire harness connector. If OK, go to Step 4. If not OK, repair the open circuit as required. 4. The relay coil battery terminal (86) is connected to the fused ignition switch output (run/start) circuit. There should be battery voltage at the cavity for relay terminal 86 with the ignition switch in the On position. If OK, go to Step 5. If not OK, repair the open circuit to the fuse in the junction block as required. 5. The coil ground terminal cavity (85) is switched to ground through the Powertrain Control Module (PCM). There should be continuity between this cavity and the A/C compressor clutch relay control circuit cavity of the PCM wire harness connector C (gray) at all times. If not OK, repair the open circuit as required. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Compressor Clutch Relay > Component Information > Description and Operation > Page 4962 Compressor Clutch Relay: Service and Repair REMOVAL AND INSTALLATION 1.

The condenser is a heat exchanger that allows the high-pressure refrigerant gas being discharged by the compressor to give up its heat to the air passing over the condenser fins. When the refrigerant gas gives up its heat, it condenses. When the refrigerant leaves the condenser, it has become a high-pressure liquid refrigerant. The volume of air flowing over the condenser fins is critical to the proper cooling performance of the air conditioning system. Therefore, it is important that there are no objects placed in front of the radiator grille openings in the front of the vehicle or foreign material on the condenser fins that might obstruct proper air flow. Also, any factory-installed air seals or shrouds must be properly reinstalled following radiator or condenser service. The condenser cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Condenser HVAC > Component Information > Specifications > Page 4968 Condenser HVAC: Service and Repair WARNING: REVIEW THE WARNINGS AND CAUTIONS BEFORE PERFORMING THE FOLLOWING OPERATION.

OVERVIEW: This bulletin involves replacing the transmission regulator valve. MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5. If a buzz/moaning/whining like noise is present, perform the Repair Procedure.

OVERVIEW: This bulletin involves replacing the transmission regulator valve. MODELS: 1996 - 1999 (AB) Ram Van 1996 - 1999 (AN) Dakota 1996 - 1999 (BR/BE) Ram Truck 1998 - 1999 (DN) Durango 1996 - 1999 (TJ) Wrangler 1996 - 1999 (XJ) Cherokee 1996 - 1998 (ZJ) Grand Cherokee 1999 (WJ) Grand Cherokee NOTE: THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A RE OR RH AUTOMATIC TRANSMISSION. SYMPTOM/CONDITION: Some vehicles may exhibit an intermittent noise from the transmission when reverse gear is selected. This noise has been described as a "buzz", whining", or "moaning" like noise. The noise is most noticeable when transmission fluid temperature is below 38 C. (100 F.). The condition is caused by a resonance of the transmission regulator valve system. Other items may cause regulator valve resonance, including air ingestion into the valve body or out of specification parts. These two items may be the result a possible cracked pump housing, a torn pump gasket, an under filled transmission, a restricted fluid filter or cooler flow, or an out of specification valve and/or valve body. You should remember these additional items / components when you perform your diagnosis. Vehicles built prior to August 1, 1995 may experience this condition if either a transmission valve body or an entire automatic transmission was replaced with components manufactured after August 1, 1995. DIAGNOSIS: Using the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostics Procedure Manual, verify all engine and transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. For 1996 and 1997 model year product, review Technical Service Bulletin 21-11-97 Rev A to determine if it applies to this vehicle before attempting to complete the analysis or repairs described in this bulletin. In most instances, the sump temperature of vehicles exhibiting transmission regulator valve resonance in reverse has been less than 38 C. (100 F). If possible, allow the suspect vehicle to remain parked in a cool place overnight. Then perform the following steps: 1. Set the vehicle parking brake. 2. Start the engine (make certain windows are closed, to eliminate outside noise). 3. With brakes applied, place the transmission selector lever in reverse. 4. Listen for any buzz/moaning/whining like noises as the transmission sump temperature rises to normal operating temperature (180 - 210 degrees F). 5.

The size of the rim is determined by the drivetrain package. Original equipment wheels/rims are designed for operation up to the specified maximum vehicle capacity. Fig. 1 All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised sections between the rim flanges and rim drop well called safety humps. Initial inflation of the tire forces the bead over these raised sections. In case of rapid loss of air pressure, the raised sections help hold the tire on the wheel. The wheel studs and nuts are designed for specific applications. All aluminum and some steel wheels have wheel stud nuts with an enlarged nose. This enlarged nose is necessary to ensure proper retention of the wheels. Do not use replacement studs or nuts with a different design or lesser quality. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Component Information > Description and Operation > Page 5047 Wheels: Testing and Inspection Inspect wheels for: Excessive run out - Dents or cracks - Damaged wheel lug nut holes - Air Leaks from any area or surface of the rim NOTE: Do not attempt to repair a wheel by hammering, heating or welding.

Excessive heat can result in bulging or other distortion, but excessive heat will not be the fault of the converter. If unburned fuel enters the converter, overheating may occur. If a converter is heat-damaged, correct the cause of the damage at the same time the converter is replaced. Also, inspect all other components of the exhaust system for heat damage. Unleaded gasoline must be used to avoid contaminating the catalyst core. DO NOT remove spark plug wires from plugs or by any other means short out cylinders. Failure of the catalytic converter can occur due to a temperature increase caused by unburned fuel passing through the converter. DO NOT allow the engine to operate at fast idle for extended periods (over 5 minutes). This condition may result in excessive temperatures in the exhaust system and on the floor pan. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information > Testing and Inspection > Component Information > Description and Operation > Page 5062 Catalytic Converter: Service and Repair CAUTION: When servicing or replacing exhaust system components, disconnect the oxygen sensor connector(s). Allowing the exhaust to hang by the oxygen sensor wires will damage the harness and/or sensor. REMOVAL 1. Raise and support the vehicle. 2. Saturate the bolts and nuts with heat valve lubricant. Allow 5 minutes for penetration. Exhaust Pipe-to-Catalytic Converter Flange Alignment-Typical 3. Remove the clamp nuts holding the catalytic converter flange to the exhaust pipe(s). Extension Pipe To Catalytic Converter Flange 4. Remove the clamp nuts holding the catalytic converter flange to the muffler or extension pipe. 5. Remove the catalytic converter. You may have to loosen up other sections of the exhaust system. INSTALLATION 1. Align and connect the catalytic converter flange to the exhaust pipe. 2. Install the catalytic converter flange into the muffler or extension pipe. 3. If other sections of the exhaust system where loosened in removal, refer to that component for the tightening procedures. 4. At the catalytic converter flange connections, install the clamp and nuts. Tighten the clamp nuts to 47 Nm (35 ft. lbs.) torque. 5. Lower the vehicle. 6. Start the engine and inspect for exhaust leaks and exhaust system contact with the body panels. Adjust the alignment, if needed. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Coupler HVAC > Component Information > Description and Operation Coupler HVAC: Description and Operation SYSTEM OPERATION Spring-lock type refrigerant line couplers are used to connect many of the refrigerant lines and other components to the refrigerant system. These couplers require a special tool for disengaging the two coupler halves. Spring-Lock Coupler - Typical The spring-lock coupler is held together by a garter spring inside a circular cage on the male half of the fitting. When the two coupler halves are connected, the flared end of the female fitting slips behind the garter spring inside the cage on the male fitting. The garter spring and cage prevent the flared end of the female fitting from pulling out of the cage. Two O-rings on the male half of the fitting are used to seal the connection. These O-rings are compatible with R- 134a refrigerant and must be replaced with O-rings made of the same material. Secondary clips are installed over the two connected coupler halves at the factory for added blow-off protection. In addition, some models have a plastic ring that is used at the factory as a visual indicator to confirm that these couplers are connected. After the coupler is connected, the plastic indicator ring is no longer needed; however, it will remain on the refrigerant line near the coupler cage. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Coupler HVAC > Component Information > Description and Operation > Page 5066 Coupler HVAC: Service and Repair WARNING: REVIEW THE WARNINGS AND CAUTIONS BEFORE PERFORMING THE FOLLOWING OPERATION. REMOVAL 1. Recover the refrigerant from the refrigerant system. See Refrigerant Recovery in the Service Procedures. 2. Remove the secondary clip from the spring-lock coupler. Refrigerant Line Spring - Lock Coupler Disconnect 3. Fit the proper size A/C line disconnect tool (Special Tool Kit 7193) over the spring-lock coupler cage. 4. Close the two halves of the A/C line disconnect tool around the spring-lock coupler. 5. Push the A/C line disconnect tool into the open side of the coupler cage to expand the garter spring. Once the garter spring is expanded and while still pushing the disconnect tool into the open side of the coupler cage, pull on the refrigerant line attached to the female half of the coupler fitting until the flange on the female fitting is separated from the garter spring and cage on the male fitting within the disconnect tool. NOTE: The garter spring may not release it the A/C line disconnect tool is cocked while pushing it into the coupler cage opening. 6. Open and remove the A/C line disconnect tool from the disconnected spring-lock coupler. 7. Complete the separation of the two halves of the coupler fitting. INSTALLATION 1. Check to ensure that the garter spring is located within the cage of the male coupler fitting, and that the garter spring is not damaged. a. If the garter spring is missing, install a new spring by pushing it into the coupler cage opening. b. If the garter spring is damaged, remove it from the coupler cage with a small wire hook (DO NOT use a screwdriver) and install a new garter spring. 2. Clean any dirt or foreign material from both halves of the coupler fitting. 3. Install new O-rings on the male half of the coupler fitting. CAUTION: Use only the specified O-rings as they are made of a special material for the R-134a system. The use of any other O-rings may allow the connection to leak intermittently during vehicle operation. 4. Lubricate the male fitting and O-rings, and the inside of the female fitting with clean R-134a refrigerant oil. Use only refrigerant oil of the type recommended for the compressor in the vehicle. 5. Fit the female half of the coupler fitting over the male half of the fitting. 6. Push together firmly on the two halves of the coupler fitting until the garter spring in the cage on the male half of the fitting snaps over the flanged end on the female half of the fitting. 7. Ensure that the spring-lock coupler is fully engaged by trying to separate the two coupler halves. This is done by pulling the refrigerant lines on either side of the coupler away from each other. 8. Reinstall the secondary clip over the spring-lock coupler cage. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Evaporator Core > Component Information > Technical Service Bulletins > Customer Interest for Evaporator Core: > 24-006-06 > Aug > 06 > A/C - Musty Odors When Hot/Humid Technical Service Bulletin # 24-006-06 Date: 060810 A/C - Musty Odors When Hot/Humid NUMBER: 24-006-06 GROUP: Heating & A/C DATE: Approval Pending THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 24-013-05, DATED AUGUST 4, 2005, WHICH SHOULD BE REMOVED FROM YOUR FILES.

The evaporator coil is positioned in the heater-A/C housing so that all air that enters the housing must pass over the fins of the evaporator before it is distributed through the system ducts and outlets. However, air passing over the evaporator coil fins will only be conditioned when the compressor is engaged and circulating refrigerant through the evaporator coil tubes. Refrigerant enters the evaporator from the fixed orifice tube as a low-temperature, low-pressure liquid. As air flows over the fins of the evaporator, the humidity in the air condenses on the fins, and the heat from the air is absorbed by the refrigerant. Heat absorption causes the refrigerant to boil and vaporize. The refrigerant becomes a low-pressure gas when it leaves the evaporator. The evaporator coil cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Evaporator Core > Component Information > Technical Service Bulletins > Page 5117 Evaporator Core: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

The fixed orifice tube is located near the front end of the rear half of the two-piece liquid line. It is accessed for service by separating the tube fitting that joins the two halves of the liquid line. Fixed Orifice Tube - Typical The inlet end of the fixed orifice tube has a nylon mesh filter screen, which filters the refrigerant and helps to reduce the potential for blockage of the metering orifice by refrigerant system contaminants. The outlet end of the tube has a nylon mesh diffuser screen. The O-rings on the plastic body of the fixed orifice tube seal the tube to the inside of the liquid line and prevent the refrigerant from bypassing the fixed metering orifice. The fixed orifice tube is used to meter the flow of liquid refrigerant into the evaporator coil. The high-pressure liquid refrigerant from the condenser expands into a low-pressure liquid as it passes through the metering orifice and diffuser screen of the fixed orifice tube. The fixed orifice tube cannot be repaired and, if faulty or plugged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Expansion Block/Orifice Tube > Component Information > Locations > Page 5122 Expansion Block/Orifice Tube: Service and Repair WARNING: REVIEW THE WARNINGS AND CAUTIONS BEFORE PERFORMING THE FOLLOWING OPERATION.

It is a heat exchanger made of rows of tubes and fins. Engine coolant is circulated through heater hoses to the heater core at all times. As the coolant flows through the heater core, heat removed from the engine is transferred to the heater core fins and tubes. Air directed through the heater core picks up the heat from the heater core fins. The blend air door allows control of the heater output air temperature by controlling how much of the air flowing through the heater-A/C housing is directed through the heater core. The blower motor speed controls the volume of air flowing through the heater-A/C housing. The heater core cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Heater Core > Component Information > Locations > Page 5128 Heater Core: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

This mechanical valve is designed to vent refrigerant from the system to protect against damage to the compressor and other system components, caused by condenser air flow restriction or an overcharge of refrigerant. The high pressure relief valve vents the system when a discharge pressure of 3445 to 4135 kPa (500 to 600 psi) or above is reached. The valve closes with a minimum discharge pressure of 2756 kPa (400 psi) is reached. The high pressure relief valve vents only enough refrigerant to reduce the system pressure, and then re-seats itself. The majority of the refrigerant is conserved in the system. If the valve vents refrigerant, it does not mean the valve is faulty. The high pressure relief valve is a factory-calibrated unit. The valve cannot be adjusted or repaired, and must not be removed or otherwise disturbed. The valve is only serviced as a part of the compressor assembly. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Specifications > A/C Discharge Hose/Line Hose/Line HVAC: Specifications A/C Discharge Hose/Line Tighten the refrigerant line manifold mounting screw to 22 N.m (200 in. lbs.). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Specifications > A/C Discharge Hose/Line > Page 5137 Hose/Line HVAC: Specifications A/C Suction Hose/Line Tighten the refrigerant line manifold mounting screw to 22 N.m (200 in. lbs.). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Locations > A/C Discharge Hose/Line Suction And Discharge Line Remove/Install - Typical Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Locations > A/C Discharge Hose/Line > Page 5140 Liquid Line Remove/Install Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Locations > A/C Discharge Hose/Line > Page 5141 Hose/Line HVAC: Locations A/C Refrigerant Hose/Line The low pressure hose (Blue with Black stripe) attaches to the suction service port located on the compressor manifold, directly over the suction port of the compressor.

High pressures are produced in the system when it is operating. Extreme care must be exercised to make sure that a]l refrigerant system connections are pressure tight. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. Sharp bends will reduce the flow of refrigerant. The flexible hose lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold. It is a good practice to inspect all flexible refrigerant system hose lines at least once a year to make sure they are in good condition and properly routed. There are two types of refrigerant fittings: All fittings with O-rings need to be coated with refrigerant oil before installation. Use only O-rings that are the correct size and approved for use with R-134a refrigerant. Failure to do so may result in a leak. - Unified plumbing connections with gaskets cannot be serviced with O-rings. The gaskets are not reusable and new gaskets do not require lubrication before installing. Using the proper tools when making a refrigerant plumbing connection is very important. Improper tools or improper use of the tools can damage the refrigerant fittings. The refrigerant must be recovered completely from the system before opening any fitting or connection. Open the fittings with caution, even after the refrigerant has been recovered. If any pressure is noticed as a fitting is loosened, tighten the fitting and recover the refrigerant from the system again. Do not discharge refrigerant into the atmosphere. Use an R. 134a refrigerant recovery/recycling device that meets SAE Standard J2210. The refrigerant system will remain chemically stable as long as pure, moisture-free R-134a refrigerant and refrigerant oil is used. Dirt, moisture, or air can upset this chemical stability Operational troubles or serious damage can occur if foreign material is present in the refrigerant system. When it is necessary to open the refrigerant system, have everything needed to service the system ready. The refrigerant system should not be left open to the atmosphere any longer than necessary. Cap or plug all lines and fittings as soon as they are opened to prevent the entrance of dirt and moisture. All lines and components in parts stock should be capped or sealed until they are to be installed. All tools, including the refrigerant recycling equipment, the manifold gauge set, and test hoses should be kept clean and dry All tools and equipment must be designed for R-134a refrigerant. SYSTEM OPERATION Refrigerant Lines The refrigerant lines and hoses are used to carry the refrigerant between the various air conditioning system components. A barrier hose design with a nylon tube inner hose liner is used for the R-134a air conditioning system on this vehicle. This nylon liner helps to further contain the R-134a refrigerant, which has a smaller molecular structure than R-12 refrigerant. The ends of the refrigerant hoses are made from lightweight aluminium or steel, and use braze-less fittings. Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system. Kinks and sharp bends reduce the flow of refrigerant in the system. A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold. High pressures are produced in the refrigerant system when the air conditioning compressor is operating. Extreme care must be exercised to make sure that each of the refrigerant system connections is pressure-tight and leak free. It is a good practice to inspect all flexible hose refrigerant lines at least once a year to make sure they are in good condition and properly routed. The refrigerant lines and hoses are coupled with other components of the HVAC system with peanut- block style fittings. A status seal type flat steel gasket with a captured compressible O-ring, is used to mate plumbing lines with A/C components to ensure the integrity of the refrigerant system. The refrigerant lines and hoses cannot be repaired and, if faulty or damaged, they must be replaced. Low Pressure Gauge Hose The low pressure hose (Blue with Black stripe) attaches to the suction service port. This port is located on the compressor manifold, directly over the suction port of the compressor. High Pressure Gauge Hose The high pressure hose (Red with Black stripe) attaches to the discharge service port. This port is located on the liquid line between the condenser and the evaporator, near the front of the engine compartment. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Locations > Page 5144 Recovery/Recycling/Evacuation/Charging Hose The center manifold hose (Yellow, or White, with Black stripe) is used to recover, evacuate, and charge the refrigerant system. When the low or high pressure valves on the manifold gauge set are opened, the refrigerant in the system will escape through this hose. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Hose/Line HVAC > Component Information > Service and Repair > A/C Discharge Hose/Line Replacement Hose/Line HVAC: Service and Repair A/C Discharge Hose/Line Replacement Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air conditioning system.

After the refrigerant system has been charged and operated, the refrigerant oil in the compressor is dispersed throughout the refrigerant system. The accumulator, evaporator, condenser, and compressor will each retain a significant amount of the needed refrigerant oil. It is important to have the correct amount of oil in the refrigerant system. This ensures proper lubrication of the compressor. Too little oil will result in damage to the compressor. Too much oil will reduce the cooling capacity of the air conditioning system. It will not be necessary to check the oil level in the compressor or to add oil, unless there has been an oil loss. An oil loss may occur due to a rupture or leak from a refrigerant line, a connector fitting, a component, or a component seal. if a leak occurs, add 30 milliliters (1 fluid ounce) of refrigerant oil to the refrigerant system after the repair has been made. Refrigerant oil loss will be evident at the leak point by the presence of a wet, shiny surface around the leak. Refrigerant Oil Capacities Chart Refrigerant oil must be added when a accumulator, evaporator coil, or condenser are replaced. See the Refrigerant Oil Capacities chart. When a compressor is replaced, the refrigerant oil must be drained from the old compressor and measured. Drain all of the refrigerant oil from the new compressor, then fill the new compressor with the same amount of refrigerant oil that was drained out of the old compressor. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Refrigerant Pressure Sensor / Switch, HVAC > High Pressure Sensor / Switch, HVAC > Component Information > Locations High Pressure Sensor / Switch: Locations High Pressure Cut-Off Switch Remove/Install The high pressure cut-off switch is located on the discharge line near the compressor. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Refrigerant Pressure Sensor / Switch, HVAC > High Pressure Sensor / Switch, HVAC > Component Information > Locations > Page 5179 High Pressure Sensor / Switch: Description and Operation SYSTEM OPERATION High Pressure Cut-off Switch The high pressure cut-off switch is located on the discharge line near the compressor. The switch is screwed onto a fitting that contains a Schrader-type valve, which allows the switch to be serviced without discharging the refrigerant system. The discharge line fitting is equipped with an O-ring to seal the switch connection.

The switch is screwed onto an accumulator fitting that contains a Schrader-type valve, which allows the switch to be serviced without discharging the refrigerant system. The accumulator fitting is equipped with an O-ring to seal the switch connection. The low pressure cycling clutch switch is connected in series electrically with the high pressure cut-off switch and the heater-A/C controls, between ground and the Powertrain Control Module (PCM). The switch contacts open and close causing the PCM to turn the compressor clutch on and off. This regulates the refrigerant system pressure and controls evaporator temperature. Controlling evaporator temperature prevents condensate water on the evaporator fins from freezing and obstructing air conditioning system air flow. The low pressure cycling clutch switch contacts are open when the suction pressure is about 141 kPa (20.5 psi) or lower. The switch contacts will close when the suction pressure rises to about 234 to 262 kPa (34 to 38 psi) or above. Lower ambient temperatures, below about -1° C (30° F), will also cause the switch contacts to open. This is due to the pressure/temperature relationship of the refrigerant in the system. The low pressure cycling clutch switch is a factory-calibrated unit. It cannot be adjusted or repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Refrigerant Pressure Sensor / Switch, HVAC > Low Pressure Sensor / Switch, HVAC > Component Information > Locations > Page 5186 Low Pressure Sensor / Switch: Testing and Inspection Before performing diagnosis of the low pressure cycling clutch switch, be certain that the switch is properly installed on the accumulator fitting.

The relay is an electromechanical device that switches battery current from a fuse in the Power Distribution Center (PDC) directly to the blower motor. The relay is energized when the relay coil is provided a voltage signal by the ignition switch. This arrangement reduces the amount of battery current that must flow through the ignition switch. The blower motor relay control circuit is protected by a fuse located in the junction block. when the relay is de-energized, the blower motor receives no battery current. The blower motor relay is located in the PDC in the engine compartment. Refer to the PDC label for blower motor relay identification and location. The blower motor relay cannot be repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Relays and Modules - HVAC > Blower Motor Relay > Component Information > Locations > Page 5193 Blower Motor Relay: Testing and Inspection Relay Test Blower Motor Relay The blower motor relay is located in the Power Distribution Center (PDC).

The terminal designations and functions are the same as a conventional ISO relay However, the micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay case dimensions are smaller than those of the conventional ISO relay. The compressor clutch relay is a electromechanical device that switches battery current to the compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the relay. The PCM responds to inputs from the heater-A/C mode control switch, the low pressure cycling clutch switch, and the high pressure cut-off switch.

The PDC is located in the engine compartment. Refer to label on PDC cover for relay location. The powertrain control module (PCM) activates the A/C compressor through the A/C clutch relay. The PCM regulates A/C compressor operation by switching the ground circuit for the A/C clutch relay on and off. When the PCM receives a request for A/C from A/C evaporator switch, it will adjust idle air control (IAC) motor position. This is done to increase idle speed. The PCM will then activate the A/C clutch through the A/C clutch relay. The PCM adjusts idle air control (IAC) stepper motor position to compensate for increased engine load from the A/C compressor. By switching the ground path for the relay on and off, the PCM is able to cycle the A/C compressor clutch. This is based on changes in engine operating conditions. If, during A/C operation, the PCM senses low idle speeds or a wide open throttle condition, it will de-energize the relay. This prevents A/C clutch engagement. The relay will remain de-energized until the idle speed increases or the wide open throttle condition exceeds 15 seconds or no longer exists. The PCM will also de-energize the relay if coolant temperature exceeds 125° C (257° F). Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Relays and Modules - HVAC > Compressor Clutch Relay > Component Information > Description and Operation > Page 5205 Compressor Clutch Relay: Testing and Inspection Relay Test Compressor Clutch Relay The compressor clutch relay is located in the Power Distribution Center (PDC).

The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a screw to the right side of the radiator yoke, behind the radiator grille and in front of the engine compartment. The ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be replaced. OPERATION The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal sent to it by the compass mini-trip computer module. The resistance in the sensor changes as temperature changes, changing the temperature sensor signal circuit voltage to the compass mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip computer module senses a specific voltage on the temperature sensor signal circuit, which it is programmed to correspond to a specific temperature. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Sensors and Switches - HVAC > Ambient Temperature Sensor / Switch HVAC > Component Information > Specifications > Page 5214 Ambient Temperature Sensor / Switch HVAC: Testing and Inspection The thermometer function is supported by the ambient temperature sensor, a wiring circuit, and a portion of the compass mini-trip computer module. If any portion of the ambient temperature sensor circuit fails, the compass/thermometer display function will self-diagnose the circuit. An "SC" (short circuit) will appear in the display in place of the temperature, when the sensor is exposed to temperatures above 110° C (230° F), or if the sensor circuit is shorted. An "OC" (open circuit) will appear in the display in place of the temperature, when the sensor is exposed to temperatures below 50° C (-58° F), or if the sensor circuit is open. The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test, and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the temperature display is inoperative or incorrect, refer to Compass Mini-Trip Computer in the Diagnosis and Testing. Sensor Test 1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the ambient temperature sensor wire harness connector. 2. Measure the resistance of the ambient temperature sensor. At -40° C (-40° F), the sensor resistance is 336 K Ohms. At 55° C (131° F), the sensor resistance is 2.488 K Ohms. The sensor resistance should read between these two values. If OK, refer to Sensor Circuit Test in the Diagnosis and Testing. If not OK, replace the faulty ambient temperature sensor. Sensor Circuit Test 1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the ambient temperature sensor wire harness connector and the overhead console wire harness connector. 2.

The switch is screwed onto a fitting that contains a Schrader-type valve, which allows the switch to be serviced without discharging the refrigerant system. The discharge line fitting is equipped with an O-ring to seal the switch connection. The high pressure cut-off switch is connected in series electrically with the low pressure cycling clutch switch between ground and the Powertrain Control Module (PCM). The switch contacts open and close causing the PCM to turn the compressor clutch on and off This prevents compressor operation when the discharge line pressure approaches high levels. The high pressure cut-off switch contacts are open when the discharge line pressure rises above about 3100 to 3375 kPa (450 to 490 psi). The switch contacts will close when the discharge line pressure drops to about 1860 to 2275 kPa (270 to 330 psi). The high pressure cut-off switch is a factory-calibrated unit. The switch cannot be adjusted or repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Sensors and Switches - HVAC > Refrigerant Pressure Sensor / Switch, HVAC > High Pressure Sensor / Switch, HVAC > Component Information > Locations > Page 5227 High Pressure Sensor / Switch: Testing and Inspection Before performing diagnosis of the high pressure cut-off switch, verify that the refrigerant system has the correct refrigerant charge.

The switch is screwed onto an accumulator fitting that contains a Schrader-type valve, which allows the switch to be serviced without discharging the refrigerant system. The accumulator fitting is equipped with an O-ring to seal the switch connection. The low pressure cycling clutch switch is connected in series electrically with the high pressure cut-off switch and the heater-A/C controls, between ground and the Powertrain Control Module (PCM). The switch contacts open and close causing the PCM to turn the compressor clutch on and off. This regulates the refrigerant system pressure and controls evaporator temperature. Controlling evaporator temperature prevents condensate water on the evaporator fins from freezing and obstructing air conditioning system air flow. The low pressure cycling clutch switch contacts are open when the suction pressure is about 141 kPa (20.5 psi) or lower. The switch contacts will close when the suction pressure rises to about 234 to 262 kPa (34 to 38 psi) or above. Lower ambient temperatures, below about -1° C (30° F), will also cause the switch contacts to open. This is due to the pressure/temperature relationship of the refrigerant in the system. The low pressure cycling clutch switch is a factory-calibrated unit. It cannot be adjusted or repaired and, if faulty or damaged, it must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Sensors and Switches - HVAC > Refrigerant Pressure Sensor / Switch, HVAC > Low Pressure Sensor / Switch, HVAC > Component Information > Locations > Page 5233 Low Pressure Sensor / Switch: Testing and Inspection Before performing diagnosis of the low pressure cycling clutch switch, be certain that the switch is properly installed on the accumulator fitting. If the switch is too loose it may not open the Schrader-type valve in the accumulator fitting, which will prevent the switch from correctly monitoring the refrigerant system pressure. Remember that lower ambient temperatures, below about -1° C (30° F), during cold weather will open the switch contacts and prevent compressor operation due to the pressure/temperature relationship of the refrigerant. Also verify that the refrigerant system has the correct refrigerant charge. See Refrigerant System Charge in the Service Procedures for more information. 1. Disconnect and isolate the battery negative cable. 2. Unplug the low pressure cycling clutch switch wire harness connector from the switch on the accumulator fitting. 3. Install a jumper wire between the two cavities of the low pressure cycling clutch switch wire harness connector. 4. Connect a manifold gauge set to the refrigerant system service ports. See Refrigerant System Service Equipment and Refrigerant System Service Ports in the Description and Operation for more information. 5. Connect the battery negative cable. 6. Place the heater-A/C mode control switch knob in any A/C position and start the engine. 7. Check for continuity between the two terminals of the low pressure cycling clutch switch. There should be continuity with a suction pressure reading of 262 kPa (38 psi) or above, and no continuity with a suction pressure reading of 141 kPa (20.5 psi) or below. If OK, test and repair the A/C switch sense circuit as required. If not OK, replace the faulty switch. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Heating and Air Conditioning > Sensors and Switches - HVAC > Refrigerant Pressure Sensor / Switch, HVAC > Low Pressure Sensor / Switch, HVAC > Component Information > Locations > Page 5234 Low Pressure Sensor / Switch: Service and Repair REMOVAL 1.

The PADS is equipped with a key cylinder so that the switch position can only be changed using an ignition key. When the ignition switch is in the On position and the passenger side airbag is disarmed, a Light-Emitting Diode (LED) illuminates an "Off" indicator lamp on the face plate of the switch. To actuate the PADS switch, insert the ignition key in the switch key cylinder. The PADS key cylinder is then rotated with the ignition key to its clockwise stop (the key cylinder slot will be aligned with the Off indicator lamp) to disarm the passenger side airbag. When the PADS key cylinder is rotated with the ignition key to its counterclockwise stop (the key cylinder slot will be in a vertical position), the Off indicator lamp will be extinguished and the passenger side airbag module will once again be armed. WARNING: THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG DISARM SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE PADS KEY CYLINDER. The PADS cannot be adjusted or repaired and, if faulty or damaged, the PADS unit must be replaced. Disarming Both Airbags Disconnect and isolate the battery negative cable. If the airbag has not been deployed, wait two minutes for the system capacitor to discharge before further service. Arming Both Airbags Prior to arming the system verify system operation as follows: A DRB scan tool is required for diagnosis of the airbag system. Refer to the proper Diagnostic Procedures for more information. 16-Way Data Link Connector - Typical 1. Connect the DRB scan tool to the 16-way data link wire harness connector. The connector is located on the driver side lower edge of the instrument panel, outboard of the steering column. 2. Turn the ignition switch to the On position. Exit the vehicle with the DRE. Use the latest version of the proper DRB cartridge. 3.. Using the DRB, read and record the active Diagnostic Trouble Code (DTC) data. 4. Read and record any stored DTC data. 5. Refer to the proper Diagnostic Procedures if any DTC is found in Step 3 or Step 4. 6. Erase the stored DTC data. If any problems remain, the stored DTC data will not erase. 7. With the ignition switch still in the ON position, make sure nobody is in the vehicle. 8. From outside of the vehicle (away from the airbag modules in case of an accidental deployment) turn the ignition switch to the OFF position for about ten seconds, and then back to the ON position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds, and then go out. This indicates that the airbag system is functioning normally NOTE: It the airbag indicator lamp fails to light, or lights and stays on, there is an airbag system malfunction. Refer to the proper Diagnostic Procedures to diagnose the problem. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Technical Service Bulletins > Driver Airbag - Trim Cover Service Air Bag: Technical Service Bulletins Driver Airbag - Trim Cover Service NUMBER: 19-009-01 GROUP: Steering DATE: Oct. 26, 2001 SUBJECT: Driver Airbag Trim Cover Service MODELS: 1999 - 2002 (AB) Ram Van 1997 - 2002 (AN) Dakota 1997 - 2002 (BE/BR) Ram Truck 1998 - 2002 (DN) Durango 2002 (DR) Ram Truck 2001 - 2002 (JR) Sebring/Sebring Convertible/Stratus 1998 - 2002 (LH) LHS/300M/Concorde/Intrepid 2001 (PT) Chrysler PT Cruiser 2001 - 2002 (RG) Chrysler Voyager (International Markets) 2001 - 2002 (RS) Town & Country/Voyager/Caravan 2000 - 2001 (R1) Dakota (International Markets) 1997 - 2002 (TJ) Wrangler 2001 - 2002 (WG) Grand Cherokee (International Markets) 1999 - 2002 (WJ) Grand Cherokee 1997 - 2002 (XJ) Cherokee 1997 - 1998 (ZG) Grand Cherokee (International Markets) 1997 - 1998 (ZJ) Grand Cherokee DISCUSSION: Driver airbag trim covers/horn switches for the above vehicles are serviceable and as such, when applicable, must be used instead of replacing the airbag module assembly.

The primary passenger restraints in this vehicle are the standard equipment factory-installed seat belts, which require active use by the vehicle occupants. The airbag system is a supplemental passive restraint that was designed and is intended to enhance the protection for the front seat occupants of the vehicle only when used in conjunction with the seat belts. See the owner's manual in the vehicle glove box for more information on the features, use and operation of all of the factory-installed passenger restraints, including the airbag system. The dual front airbag system consists of the following components: Airbag Control Module (ACM) - Airbag indicator lamp - Clockspring - Driver and passenger side airbag modules (including the airbag inflators) - Driver and passenger side knee blockers - Passenger side airbag on/off switch - Wire harness and connections. This information provides complete service information for the ACM, both airbag modules, the clockspring, and the passenger side airbag on/off switch. Complete service information for the other airbag system components can be located as follows: Refer to Instrument Cluster in the Instrument Panel Systems for complete service information for the airbag indicator lamp. - Refer to Steering Column Opening Cover in the Replacement of Instrument Panel Systems for complete service information on the driver side knee blocker. - Refer to Glove Box in the Replacement of Instrument Panel Systems for complete service information on the passenger side knee blocker. See the proper Diagnostic Procedures to test or diagnose a problem with any component of the airbag system. OPERATION The airbag system electrical circuits are continuously monitored and controlled by a microprocessor and software contained within the Airbag Control Module (ACM). The ACM also contains an impact sensor and a safing sensor, which are monitored by the ACM to determine when an impact occurs that is severe enough to require airbag system protection. When a frontal impact is severe enough, the ACM signals the inflator units of both airbag modules to deploy the airbags. An airbag indicator lamp in the instrument cluster lights for about seven seconds as a bulb test, each time the ignition switch is turned to the On or Start positions. Following the bulb test, the airbag indicator lamp is turned on or off by the ACM to indicate the status of the airbag system. If the airbag indicator lamp comes on at any time other than during the bulb test, it indicates that there is a problem in the airbag system circuits. Such a problem may cause the airbags not to deploy when required, or to deploy when not required. The driver side airbag module includes an inflatable airbag and an inflator unit behind a trim cover in the hub area of the steering wheel. The passenger side airbag module includes a second inflatable airbag and an inflator unit behind an airbag door in the instrument panel above the glove box. During a frontal vehicle impact, the knee blockers work in concert with properly adjusted seat belts to restrain the driver and front seat passenger in the proper position for an airbag deployment. The knee blockers also work to absorb and distribute the crash energy from the driver and front seat passenger to the structure of the instrument panel. The driver side knee blocker is integral to the instrument panel steering column opening cover. The passenger side knee blocker is integral to the glove box door. WARNING: THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIR- BAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. - THE DRIVER SIDE AIRBAG MODULE INFLATOR ASSEMBLY CONTAINS SODIUM AZIDE AND POTASSIUM NITRATE. THESE MATERIALS ARE POISONOUS AND EXTREMELY FLAMMABLE. CONTACT WITH ACID, WATER, OR HEAVY METALS MAY PRODUCE HARMFUL AND IRRITATING GASES (SODIUM HYDROXIDE IS FORMED IN THE PRESENCE OF MOISTURE) OR COMBUSTIBLE COMPOUNDS. THE PASSENGER AIRBAG MODULE CONTAINS ARGON GAS PRESSURIZED TO OVER 2500 PSI. DO NOT ATTEMPT TO DISMANTLE AN AIR BAG MODULE OR TAMPER WITH ITS INFLATOR. DO NOT PUNCTURE, INCINERATE, OR BRING INTO CONTACT WITH ELECTRICITY.

THEY MUST NEVER BE REPLACED WITH ANY SUBSTITUTES. ANY TIME A NEW FASTENER IS NEEDED, REPLACE IT WITH THE CORRECT FASTENERS PROVIDED IN THE SERVICE PACKAGE OR SPECIFIED IN THE CHRYSLER MOPAR PARTS CATALOG. - WHEN A STEERING COLUMN HAS AN AIRBAG MODULE ATTACHED, NEVER PLACE THE COLUMN ON THE FLOOR OR ANY OTHER SURFACE WITH THE STEERING WHEEL OR AIRBAG MODULE FACE DOWN. DRIVER SIDE AIRBAG MODULE DESCRIPTION The driver side airbag module protective trim cover is the most visible part of the driver side airbag system. The driver side airbag module is mounted directly to the steering wheel. Located under the airbag module trim cover are the horn switch, the folded airbag cushion, and the airbag cushion supporting components. The resistive membrane-type horn switch is secured with heat stakes to the inside surface of the airbag module trim cover, between the trim cover and the folded airbag cushion. The driver side airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. The driver side airbag module trim cover and the horn switch are available as a unit for service replacement. OPERATION The driver side airbag module includes a stamped metal housing to which the cushion and an inflator unit are attached and sealed. The conventional pyrotechnic-type inflator assembly is mounted to studs on the back of the airbag module housing. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. Following an airbag deployment, the airbag cushion quickly deflates by venting this gas towards the instrument panel through the porous fabric material used on the steering wheel side of the airbag cushion. The protective trim cover is fitted to the front of the airbag module and forms a decorative cover in the center of the steering wheel. The inside of the trim cover has locking blocks molded into it that engage a lip on the airbag module metal housing. Two stamped metal retainers then fit over the inflator mounting studs on the back of the airbag module housing and are engaged in slots on the inside of the cover, securely locking the trim cover into place. The trim cover will split at predetermined breakout lines, then fold back out of the way along with the horn switch upon airbag deployment. PASSENGER SIDE AIRBAG MODULE DESCRIPTION The passenger side airbag door on the instrument panel above the glove box is the most visible part of the passenger side airbag system. Located under the airbag door are the passenger side airbag cushion and the airbag cushion supporting components. The passenger side airbag module includes an extruded aluminum housing within which the cushion and inflator are mounted and sealed. The airbag housing extrusion also includes two flanges. The flanges, one at the top and one at the bottom, serve as the mounting brackets for the module. Two stamped metal brackets, one on each end of the housing, enclose the cushion and inflator. The passenger side airbag module upper bracket is secured beneath the instrument panel top pad with rivets to a flange and bracket on the passenger side airbag door. The lower bracket is secured with screws to the instrument panel structural duct. Following a passenger side airbag deployment, the passenger side airbag module and the instrument panel assembly must be replaced. The passenger side airbag module cannot be repaired, and must be replaced if deployed or in any way damaged. OPERATION The hybrid-type inflator assembly includes a small canister of highly compressed argon gas. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. Following an airbag deployment, the airbag cushion quickly deflates by venting this gas through the porous fabric material used on each end panel of the airbag cushion. The molded plastic passenger side airbag door is secured to the instrument panel top cover with rivets. The airbag door has predetermined breakout lines concealed beneath its decorative cover. Upon airbag deployment, the airbag door will split at the breakout lines and the door will pivot out of the way. The passenger side airbag door is serviced only as a unit with the instrument panel top cover. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Technical Service Bulletins > Page 5270 Air Bag: Testing and Inspection A DRB scan tool is required for diagnosis of the airbag system. See the proper Diagnostic Procedures for more information. 16-Way Data Link Connector - Typical 1. Connect the DRB scan tool to the 16-way data link wire harness connector. The connector is located on the driver side lower edge of the instrument panel, below the steering column. 2. Turn the ignition switch to the On position. Exit the vehicle with the DRB. Be certain that the DRB contains the latest version of the proper DRB software. 3. Using the DRB, read and record the active Diagnostic Trouble Code (DTC) data. 4. Read and record any stored DTC data. 5. See the proper Diagnostic Procedures if any DTC is found in Step 3 or Step 4. 6. After completing the necessary repairs, try to erase the stored DTC data. If any problems remain, the stored DTC data will not erase. See the proper Diagnostic Procedures for the procedures to diagnose any stored DTC that will not erase. 7. With the ignition switch still in the On position, check to be certain that nobody is in the vehicle. 8. From outside of the vehicle (away from the airbags in case of an accidental deployment) turn the ignition switch to the Off position for about ten seconds, and then back to the On position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds, and then go out. This indicates that the airbag system is functioning normally. NOTE: If the airbag indicator lamp fails to light, or lights and stays on, there is an airbag system malfunction. See the proper Diagnostic Procedures to diagnose the problem. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Service and Repair > Airbag System Service Air Bag: Service and Repair Airbag System Service NON-DEPLOYED At no time should any source of electricity be permitted near the inflator on the back of an airbag module. When carrying a non-deployed airbag module, the trim cover or airbag side of the module should be pointed away from the body to minimize injury in the event of an accidental deployment. If the module is placed on a bench or any other surface, the trim cover or airbag side of the module should be face up to minimize movement in the event of an accidental deployment. In addition, the airbag system should be disarmed whenever any steering wheel, steering column, or instrument panel components require diagnosis or service. Failure to observe this warning could result in accidental airbag deployment and possible personal injury. Refer to instrument Panel Systems for additional service procedures on the instrument panel components. Disposal Of Non-deployed Airbag Modules All damaged or faulty and non-deployed driver side or passenger side airbag modules which are replaced on vehicles are to be returned. If an airbag module assembly is faulty or damaged and non-deployed, refer to the parts return list in the current Chrysler Corporation Warranty Policies and Procedures for the proper handling and disposal procedures. DEPLOYED Any vehicle which is to be returned to use after an airbag deployment, must have both airbag modules, the instrument panel assembly, the steering column assembly and the clockspring replaced. These components will be damaged or weakened as a result of an airbag deployment, which may or may not be obvious during a visual inspection, and are not intended for reuse. Other vehicle components should be closely inspected, but are to be replaced only as required by the extent of the visible damage incurred. STORAGE An airbag module must be stored in its original, special container until used for service. Also, it must be stored in a clean, dry environment; away from sources of extreme heat, sparks, and high electrical energy. Always place or store an airbag module on a surface with its trim cover or airbag side facing up, to minimize movement in case of an accidental deployment. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Service and Repair > Airbag System Service > Page 5273 Air Bag: Service and Repair Cleanup Procedure Wear Safety Glasses and Rubber Gloves - Typical Following an airbag system deployment, the vehicle interior will contain a powdery residue. This residue consists primarily of harmless particulate by-products of the small pyrotechnic charge used to initiate the airbag deployment propellant. However, this residue will also contain traces of sodium hydroxide powder, a chemical by-product of the propellant material that is used to generate the nitrogen gas that inflates the airbag. Since sodium hydroxide powder can irritate the skin, eyes, nose, or throat, be sure to wear safety glasses, rubber gloves, and a long-sleeved shirt during cleanup. WARNING: IF YOU EXPERIENCE SKIN IRRITATION DURING CLEANUP, RUN COOL WATER OVER THE AFFECTED AREA. ALSO, IF YOU EXPERIENCE IRRITATION OF THE NOSE OR THROAT, EXIT THE VEHICLE FOR FRESH AIR UNTIL THE IRRITATION CEASES. IF IRRITATION CONTINUES, SEE A PHYSICIAN. Begin the cleanup by removing the airbag modules from the vehicle. Refer to Driver Side Airbag Module and Passenger Side Airbag Module in the Replacement for the procedures. Use a vacuum cleaner to remove any residual powder from the vehicle interior. Clean from outside the vehicle and work your way inside, so that you avoid kneeling or sitting on a non-cleaned area. Vacuum Heater and A/C Outlets - Typical Be sure to vacuum the heater and air conditioning outlets as well. Run the heater and air conditioner blower on the lowest speed setting and vacuum any powder expelled from the outlets. You may need to vacuum the interior of the vehicle a second time to recover all of the powder. Place the deployed airbag modules in your vehicular scrap pile. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Service and Repair > Airbag System Service > Page 5274 Air Bag: Service and Repair Driver Side Airbag Module Replacement The following procedure is for replacement of a faulty or damaged driver side airbag module.

The ACM contains an electronic microprocessor, an electronic impact sensor, an electromechanical safing sensor, and an energy storage capacitor. The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. OPERATION The microprocessor in the ACM contains the airbag system logic. The airbag system logic includes On-Board Diagnostics (OBD), and the ability to communicate with the instrument cluster circuitry over the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor continuously monitors all of the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster over the CCD data bus to turn on the airbag indicator lamp. Refer to Instrument Cluster in the Instrument Panel Systems for more information on the airbag indicator lamp. One electronic impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate as signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbags. In addition to the electronic impact sensor, there is an electromechanical sensor within the ACM called a safing sensor. The safing sensor is a normally open series switch located in the airbag deployment circuit of the ACM. This sensor detects impact energy of a lesser magnitude than the electronic impact sensor, and must be closed in order for the airbags to deploy The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags for up to one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact, if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag Control Module > Component Information > Specifications > Page 5289 Air Bag Control Module: Service and Repair WARNING: - THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG.

When diagnosing any airbag squib circuit Diagnostic Trouble Code (DTC) with a DRBIII(R), the use of the Airbag Load Tool (Special Tool 8310 and 8443) is required. The Airbag Load Tool, used in conjunction with the DRBIII(R) are used to isolate and test components and wiring for failure. Only replace the component or wiring that has failed. This will reduce unnecessary cost to the customer or DaimlerChrysler. NOTE: AIRBAG REPLACEMENT IS NOT REQUIRED EVERY TIME IT IS REMOVED OR WHEN ANOTHER COMPONENT HAS FAILED. USE OF THE DRBIII(R) AND AIRBAG LOAD TOOL WILL DETERMINE IF THE AIRBAG HAS FAILED AND REPLACEMENT IS NEEDED. NOTE: Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Clockspring Assembly / Spiral Cable, Air Bag > Component Information > Technical Service Bulletins > Airbag/Clock Spring - Service > Page 5317 TECHNICIANS SHOULD RECORD ALL STORED AND ACTIVE AIRBAG SYSTEM FAULT CODES ON THE REPAIR ORDER. Clock Springs Recent analysis of returned clock springs have indicated that prior service may have contributed to the clock spring's failure. ^ Do not use silicone or any other lubricant spray on or near the clock spring. Lubricants are often used in the clock spring area of the steering column to eliminate noise. Lubricants may have an adverse effect on the clock spring. ^ Clock spring centering. Any repair that may disrupt the positioning of the steering wheel with the front wheels will require that the clock spring be centered.

The clockspring is used to maintain a continuous electrical circuit between the fixed clockspring wire harness on the steering column and several electrical components that rotate with the steering wheel. The rotating components include the driver side airbag module, the horn switch and, if the vehicle is so equipped, the vehicle speed control switches and/or the remote radio switches. The clockspring cannot be repaired. If the clockspring is faulty, damaged, or if the driver side airbag has been deployed, the clockspring must be replaced. OPERATION The clockspring assembly consists of a plastic case which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds like a clockspring with the steering wheel rotation. The electrically conductive tape consists of several fine gauge copper wire leads sandwiched between two narrow strips of plastic film. Like the clockspring in a timepiece, the clockspring tape has travel limits and can be damaged by being wound too tightly. To prevent this from occurring, the clockspring is centered when it is installed on the steering column. Centering the clockspring indexes the clockspring tape to other steering components so that it can operate within its designed travel limits. However, if the clockspring is removed for service or if the steering column is disconnected from the steering gear allowing the clockspring tape to change position relative to the other steering components, it must be re-centered following completion of the service or it may be damaged. Refer to Clockspring Centering in the Adjustments for the proper centering procedures. Service replacement clocksprings are shipped precentered and with a piece of tape covering the depressed clockspring auto-locking tabs. This tape should not be removed until the clockspring has been installed on the steering column. If the tape is removed before the clockspring is installed on a steering column, the clockspring centering procedure must be performed. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Clockspring Assembly / Spiral Cable, Air Bag > Component Information > Technical Service Bulletins > Page 5323 Clockspring Assembly / Spiral Cable: Adjustments The clockspring is designed to wind and unwind when the steering wheel is rotated, but is only designed to rotate the same number of turns (about five complete rotations) as the steering wheel can be turned from stop to stop. Centering the clockspring indexes the clockspring tape to other steering components so that it can operate within its designed travel limits. The rotor of a centered clockspring can be rotated two and one-half turns in either direction from the centered position, without damaging the clockspring tape. However, if the clockspring is removed for service or if the steering column is disconnected from the steering gear, the clockspring tape can change position relative to the other steering components. The clockspring must then be re-centered following completion of the service or the clockspring tape may be damaged. Service replacement clocksprings are shipped precentered and with a piece of tape covering the depressed auto-locking tabs. This tape should not be removed until the clockspring has been installed on the steering column. If the tape is removed before the clockspring is installed on a steering column, the clockspring centering procedure must be performed. WARNING: THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NOTE: Before starting this procedure, be certain to turn the steering wheel until the front wheels are in the straight-ahead position. 1. Place the front wheels in the straight-ahead position. 2. Remove the clockspring from the steering column. Refer to Clockspring/Service and Repair for this procedure. Fig. 43 Auto-locking clockspring 3. Depress the two plastic clockspring auto-locking tabs. 4. Keeping the auto-locking tabs depressed, rotate the clockspring hub clockwise to the end of its travel. Do not apply excessive torque. 5. From the end of the clockwise travel, rotate the hub about two and one-half turns counterclockwise, then release the auto-locking tabs. The clockspring horn wire harness should end up at the top, and the airbag, optional speed control and optional remote radio wire harnesses at the bottom. 6. The front wheels should still be in the straight-ahead position. Install the clockspring onto the steering column. Refer to Clockspring/Service and Repair for this procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Clockspring Assembly / Spiral Cable, Air Bag > Component Information > Technical Service Bulletins > Page 5324 Clockspring Assembly / Spiral Cable: Service and Repair The clockspring cannot be repaired.

The ACM contains an electronic microprocessor, an electronic impact sensor, an electromechanical safing sensor, and an energy storage capacitor. The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced. OPERATION The microprocessor in the ACM contains the airbag system logic. The airbag system logic includes On-Board Diagnostics (OBD), and the ability to communicate with the instrument cluster circuitry over the Chrysler Collision Detection (CCD) data bus to control the airbag indicator lamp. The microprocessor continuously monitors all of the airbag system electrical circuits to determine the system readiness. If the ACM detects a monitored system fault, it sends messages to the instrument cluster over the CCD data bus to turn on the airbag indicator lamp. Refer to Instrument Cluster in the Instrument Panel Systems for more information on the airbag indicator lamp. One electronic impact sensor is used in this airbag system. The impact sensor is an accelerometer that senses the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. The impact sensor is calibrated for the specific vehicle, and is only serviced as a unit with the ACM. A pre-programmed decision algorithm in the ACM microprocessor determines when the deceleration rate as signaled by the impact sensor indicates an impact that is severe enough to require airbag system protection. When the programmed conditions are met, the ACM sends an electrical signal to deploy the airbags. In addition to the electronic impact sensor, there is an electromechanical sensor within the ACM called a safing sensor. The safing sensor is a normally open series switch located in the airbag deployment circuit of the ACM. This sensor detects impact energy of a lesser magnitude than the electronic impact sensor, and must be closed in order for the airbags to deploy The ACM also contains an energy-storage capacitor. This capacitor stores enough electrical energy to deploy the airbags for up to one second following a battery disconnect or failure during an impact. The purpose of the capacitor is to provide airbag system protection in a severe secondary impact, if the initial impact has damaged or disconnected the battery, but was not severe enough to deploy the airbags. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Relays and Modules - Restraint Systems > Air Bag Control Module > Component Information > Specifications > Page 5346 Air Bag Control Module: Service and Repair WARNING: - THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG.

The PADS is equipped with a key cylinder so that the switch position can only be changed using an ignition key. When the ignition switch is in the On position and the passenger side airbag is disarmed, a Light-Emitting Diode (LED) illuminates an "Off" indicator lamp on the face plate of the switch. To actuate the PADS switch, insert the ignition key in the switch key cylinder. The PADS key cylinder is then rotated with the ignition key to its clockwise stop (the key cylinder slot will be aligned with the Off indicator lamp) to disarm the passenger side airbag. When the PADS key cylinder is rotated with the ignition key to its counterclockwise stop (the key cylinder slot will be in a vertical position), the Off indicator lamp will be extinguished and the passenger side airbag module will once again be armed. WARNING: THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG DISARM SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE PADS KEY CYLINDER. The PADS cannot be adjusted or repaired and, if faulty or damaged, the PADS unit must be replaced. Disarming Both Airbags Disconnect and isolate the battery negative cable. If the airbag has not been deployed, wait two minutes for the system capacitor to discharge before further service. Arming Both Airbags Prior to arming the system verify system operation as follows: A DRB scan tool is required for diagnosis of the airbag system. Refer to the proper Diagnostic Procedures for more information. 16-Way Data Link Connector - Typical 1. Connect the DRB scan tool to the 16-way data link wire harness connector. The connector is located on the driver side lower edge of the instrument panel, outboard of the steering column. 2. Turn the ignition switch to the On position. Exit the vehicle with the DRE. Use the latest version of the proper DRB cartridge. 3.. Using the DRB, read and record the active Diagnostic Trouble Code (DTC) data. 4. Read and record any stored DTC data. 5. Refer to the proper Diagnostic Procedures if any DTC is found in Step 3 or Step 4. 6. Erase the stored DTC data. If any problems remain, the stored DTC data will not erase. 7. With the ignition switch still in the ON position, make sure nobody is in the vehicle. 8. From outside of the vehicle (away from the airbag modules in case of an accidental deployment) turn the ignition switch to the OFF position for about ten seconds, and then back to the ON position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds, and then go out. This indicates that the airbag system is functioning normally NOTE: It the airbag indicator lamp fails to light, or lights and stays on, there is an airbag system malfunction. Refer to the proper Diagnostic Procedures to diagnose the problem. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Seat Belt Systems > Child Restraint > Child Seat Tether Attachment > Component Information > Technical Service Bulletins > Restraints - Child Seat Tether Installation Child Seat Tether Attachment: Technical Service Bulletins Restraints - Child Seat Tether Installation NUMBER: 23-029-08 GROUP: Body DATE: October 24, 2008 THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 23-08-00 REV.

The passenger side airbag on/off switch is equipped with a key actuator so that the switch position can only be changed using an ignition key. When the ignition switch is in the On position and the passenger side airbag system is disabled, a Light-Emitting Diode (LED) illuminates an Off indicator lamp on the face plate of the switch. The passenger side airbag on/off switch cannot be adjusted or repaired and, if faulty or damaged, the switch assembly must be replaced. OPERATION To actuate the passenger side airbag on/off switch, insert the ignition key in the switch key actuator. The switch key actuator is then rotated with the ignition key to its clockwise stop (the key actuator slot will be aligned with the Off indicator lamp) to disable the passenger side airbag system. When the switch key actuator is rotated with the ignition key to its counterclockwise stop (the key actuator slot will be in a vertical position), the Off indicator lamp will be extinguished and the passenger side airbag system will be enabled. WARNING: THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER SIDE AIRBAG ON/OFF SWITCH KEY ACTUATOR AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE SWITCH KEY ACTUATOR. FAILURE TO OBSERVE THIS WARNING COULD RESULT IN ACCIDENTAL, INCOMPLETE OR IMPROPER AIR BAG DEPLOYMENT AND POSSIBLE OCCUPANT INJURIES. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Restraint Systems > Sensors and Switches - Restraint Systems > Air Bag Deactivation Switch > Component Information > Technical Service Bulletins > Page 5435 Air Bag Deactivation Switch: Service and Repair WARNING: THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Diagram Information and Instructions > Page 5448 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Diagram Information and Instructions > Page 5449 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Diagram Information and Instructions > Page 5450 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Diagram Information and Instructions > Page 5451 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Diagram Information and Instructions > Page 5452 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Diagram Information and Instructions > Page 5453 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Diagram Information and Instructions > Page 5464 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Diagram Information and Instructions > Page 5465 Antenna Tests Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Page 5466 Antenna: Service Precautions WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY . Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Page 5467 Antenna: Description and Operation DESCRIPTION All models use a fixed-length stainless steel rod-type antenna mast, installed on the right front fender of the vehicle. The antenna mast has a spiral groove cut down its length to reduce wind noise. The antenna mast is connected to the center wire of the coaxial antenna cable, and is not grounded to any part of the vehicle. To eliminate static, the antenna base must have a good ground. The coaxial antenna cable shield (the outer wire mesh of the cable) is grounded to the antenna base and the radio receiver chassis. The antenna coaxial cable has an additional disconnect, located near the inboard side of the glove box opening on the back side of the lower instrument panel reinforcement. This additional disconnect allows the instrument panel assembly to be removed and installed without removing the radio receiver. The factory-installed Electronically Tuned Radios (ETR) automatically compensate for radio antenna trim. Therefore, no antenna trimmer adjustment is required or possible when replacing the radio receiver or the antenna. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Page 5468 Antenna: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. The following four tests are used to diagnose the antenna with an ohmmeter: - Test 1 - Mast to ground test - Test 2 - Tip-of-mast to tip-of-conductor test - Test 3 - Body ground to battery ground test - Test 4 - Body ground to coaxial shield test. Antenna Tests The ohmmeter test lead connections for each test are shown in Antenna Tests. NOTE: This model has a special coating on the antenna mast which is not electrically conductive. Remove the antenna mast from the antenna base before attempting to perform Tests 1 and 2. NOTE: This model has a two-piece antenna coaxial cable. Tests 2 and 4 must be conducted in two steps to isolate a coaxial cable problem; from the coaxial cable connection under the right end of the instrument panel near the inboard side of the glove box opening to the antenna base, and then from the coaxial cable connection to the radio chassis connection. Test 1 Test 1 determines if the antenna mast is insulated from tile base. Proceed as follows: 1. Disconnect the antenna coaxial cable connector from the radio receiver chassis and isolate. Remove the antenna mast from the antenna base. 2. Insert one ohmmeter test lead into the socket for the antenna mast in the center of the antenna base. Connect the other test lead to the perimeter of the antenna base. Check for continuity. 3. There should be no continuity. If continuity is found, replace the faulty or damaged antenna base and cable assembly. Test 2 Test 2 checks the antenna for an open circuit as follows: 1. Disconnect the antenna coaxial cable connector from the radio receiver chassis. Remove the antenna mast from the antenna base. 2. Insert one ohmmeter test lead into the socket for the antenna mast in the center of the antenna base. Connect the other test lead to the center pin of the antenna coaxial cable connector. 3. Continuity should exist (the ohmmeter should only register a fraction of an ohm). High or infinite resistance indicates damage to the base and cable assembly. Replace the faulty base and cable, if required. Test 3 Test 3 checks the condition of the vehicle body ground connection. This test should be performed with the battery positive cable removed from the battery. Disconnect both battery cables, the negative cable first. Reconnect the battery negative cable and perform the test as follows: 1. Connect one ohmmeter test lead to the vehicle fender. Connect the other test lead to the battery negative terminal post. 2. The resistance should be less than one ohm. 3. If the resistance is more than one ohm, check the braided ground strap(s) connected to the engine and the vehicle body for being loose, corroded, or damaged. Repair the ground strap connections, if required. Test 4 Test 4 checks the condition of the ground between the antenna base and the vehicle body as follows: Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Page 5469 1. Connect one ohmmeter test lead to the vehicle fender. Connect the other test lead to the outer crimp on the antenna coaxial cable connector. 2. The resistance should be less then one ohm. 3. If the resistance is more then one ohm, clean and/or tighten the antenna base to fender mounting hardware. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antenna > Component Information > Diagrams > Page 5470 Antenna: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The CTM also contains the program logic and control circuitry for the RKE system. The CTM is mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening. The RKE receiver has a memory function to retain the vehicle access codes of up to four RKE transmitters. The receiver is designed to retain the transmitter codes in memory, even if the battery is disconnected. The RKE receiver is energized by one of three radio frequency inputs from the RKE transmitter; Unlock, Lock, or Panic. The programming of the CTM responds to these RKE inputs, as well as many other inputs, by sending the proper control outputs to the power lock motors, the courtesy lamp circuit, the horn relay, and the headlamp relay. For diagnosis or programming of the RKE receiver within the high-line CTM, a DRB scan tool and the proper Diagnostic Procedures are recommended. The RKE receiver is only serviced as a unit with the high-line CTM and, if faulty or damaged, the CTM unit must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Antitheft and Alarm Systems > Keyless Entry > Keyless Entry Transmitter > Keyless Entry Transmitter Battery > Component Information > Service and Repair Keyless Entry Transmitter Battery: Service and Repair The Remote Keyless Entry (RKE) transmitter case snaps open and shut for battery access.

It is being provided with this Technical Service Bulletin to assist in properly installing communication equipment in DaimlerChrysler vehicles. This information should be given to any owner inquiring about installing radio-transmitting equipment. Installation Recommendations DaimlerChrysler Radio Communication Equipment Installation Recommendations Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Cellular Phone > Component Information > Technical Service Bulletins > Radio Communication Equipment - Recommendations > Page 5505 The following is excerpted from the owners manual of new DaimlerChrysler products: "INSTALLATION OF RADIO TRANSMITTING EQUIPMENT Special design considerations are incorporated into this vehicle's electronic system to provide immunity to radio frequency signals. Mobile two-way radio and telephone equipment must be installed properly by trained personnel. The following must be observed during installation. The positive power connection should be made directly to the battery and fused as close to the battery as possible. The negative power connection should be made to body sheet metal adjacent to the negative battery connection. This connection should not be fused. Antennas for two-way radios should be mounted on the roof or the rear area of the vehicle. Care should be used in mounting antennas with magnet bases. Magnets may affect the accuracy or operation of the compass on vehicles so equipped. The antenna cable should be as short as practical and routed away from the vehicle wiring when possible. Use only fully shielded coaxial cable. Carefully match the antenna and cable to the radio to ensure a low Standing Wave Ratio (SWR). Mobile radio equipment with output power greater than normal may require special precautions. All installations should be checked for possible interference between the communications equipment and the vehicle's electronic systems. A Technical Service Bulletin (TSB) is available for detailed assistance." The owner's first line of contact regarding vehicle problems is the dealer. The literature supplied with each vehicle lists the steps to be taken in the event the dealer is unable to resolve the problem. To assist in properly installing communications equipment in DaimlerChrysler vehicles, the following information is provided. Always use good construction practices (see The ARRL Handbook or other standard reference works). The information contained in this guide has been prepared for use by persons installing two-way radio equipment (transmitters and receivers) in vehicles. It has been prepared in accordance with current engineering principles and generally accepted practices, using the best information available at the time of publication. It is not possible to cover all of the possible installations of two-way radio equipment in this guide. Accordingly, DaimlerChrysler Corporation cannot be held responsible for incidental or consequent damages arising out of the use of the information contained herein. The responsibility for installations and modifications is the sole responsibility of the customer. The installation recommendations presented here are intended to supplement the radio manufacturer's instructions. Test the entire installation for anomalies, especially drivetrain and brake control before extensive driving. 1. CONTROLS Mount the transceiver to a solid surface. If you use screws through the floor pan, put body sealer over the underbody projections. (Stamped acorn nuts, filled with sealer are available at most body shops for this purpose.) This will keep moisture out of the carpet and insulation, and will forestall rust in this area. Watch out for wire harnesses routed under carpet and behind instrument panel. If you mount the radio under the instrument panel, be sure that there is no interference with proper operation of the foot controls. Mount the control head or front panel (especially the microphone cable) so that it is clear of the steering wheel and column controls and passenger airbag. If the unit is heavy, extra bracing may be needed for stability. Newer vehicles have more structure and energy absorbing materials in the knee blocker (the lower part of the Instrument Panel). For one-piece transceivers, if ignition switch control is desired, it is good practice to use a power relay to avoid overloading the ignition switch, and to maintain the advantages of direct battery feed. Try the installation out before you start drilling holes. 2. POWER WIRING To reduce the hazard of working on the vehicle, disconnect the battery NEGATIVE before beginning work. Note that some components may lose short-term memory (e.g.: radio presets) after a protracted time without battery power. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Cellular Phone > Component Information > Technical Service Bulletins > Radio Communication Equipment - Recommendations > Page 5506 For low or medium power transmitters (up to 55W FM or 110W SSB or CW), the power outlet or cigar lighter feed may be used. Use a 1/4" jumper terminal at the socket or splice (solder and heat shrink or tape). For higher power transmitters, including amplifiers, connect the power (battery +) lead at the battery or at the power distribution center or at the positive jump-start post, if the vehicle has one. An appropriate terminal should be used. If the terminal is exposed to the weather, solder and apply a commercial protectant (wheel bearing grease is an acceptable alternative.) to retard corrosion. This lead should be fused as close to the battery as practical to protect the wiring (and the vehicle)! If the power connection is underhood, use a weatherproof fuse holder. Motorola Communications Division supplies a weatherproof holder, part number 09-84277B01 for 5AG cartridge fuses that is part of their standard installation kit. Packard Electric Division of Delphi Automotive Systems makes an insulator, part number 12033769, terminal number 12020156 with cover 12033731 for standard SAE plastic fuses. Vinyl-insulated wire, typically supplied with transceivers is not entirely suitable for the higher underhood temperatures in modern vehicles. Route underhood wiring away from all hot areas. Body sheet metal, away from the exhaust, radiator, A/C liquid line and engine is usually the coolest location. DO NOT FUSE THE GROUND LEAD. If the ground-side fuse were to open, the entire supply current would be conducted by an alternate current return path, which could cause the feedline to overheat, with possible resulting damage. For low or medium power installations, connect the ground (battery -) to body sheet near the power feed point. If you use a screw through the floor, put body sealer over the underbody projection. (Stamped acorn nuts, filled with sealer are available at most body shops for this purpose.) For high power installations, connect the ground (battery -) lead at the battery connection to the body. This is usually a 6 or 8 AWG black wire from the battery negative terminal to a screw at the wheelhouse or radiator support. If a separate sheet metal ground is used, clean the paint off a one inch or so diameter area of body panel where the ground lead is to be connected (usually the case with commercial trunk mount radios). An awl is the best tool to use to pierce a starting hole for a #12 or 5mm, minimum plated ground screw. A ring terminal with lockwasher serrations of the proper size for the screw or a separate serrated (not a split or SAE) lockwasher should be used between the terminal and the screw head. As above, some grease or protectant should be used if the connection is in an unprotected area. If the power cable must pass through the dash panel, try to find an existing hole with a grommet that is unused. If none is available, pull the carpet back from under the dash panel in the passenger footwell in the cabin. Locate a place where there are no other components on either side, as high up as possible. An awl is the best tool to use to punch a small hole through to the engine compartment. If the position is good, enlarge the hole by driving the awl in up to the shank. If this is not large enough to easily pass the cable, enlarge it by using a larger tapered punch. This will leave an extruded hole with no sharp edges. Install the cable and seal the hole with silicone RTV or commercial body sealer on both sides. Seal any extra holes that you may have made. Dress the underhood wiring so that it is sate from all hazards, which include the following: exhaust manifold, steering shaft, throttle linkage, fans, etc. Tie wrap as required. 3. CABLING Route control cables under the floor mats, inside the corner where the floor pan meets the rocker panel for best protection. Remove the sill plates and tuck the cable under the floor mats or carpet and padding. For most left hand drive vehicles, use the right side for best separation to the main body harness (usually on the left side). Route the cable along the extreme outboard edge of the floor pan, under the side trim, if possible. 4. REMOTE TRANSCEIVER For trunk mount installations in passenger cars, you may need to remove the rear seat cushion and seat back to get the cable into the trunk. The seat cushion is usually clipped at the front, lower edge by its own frame: push down and back, then lift. Note the front and rear clipping points for ease of reinstallation. The seat back is usually clipped to the rear compartment inner panel: pull out at the bottom and slide up to remove. Again, note the clipping points for ease of reinstallation. There is usually a vapor/sound barrier behind the seat back, which must be pierced to pass the cable. Open the trunk and pick a spot where the cable is safe from chafing on any sharp sheet metal. Tie wrap or tape in place at this location. Repair the barrier sheet if necessary. Replace the seat back and cushion, taking care that the cable is not pinched by the seat cushion when there is someone sitting in the seat. On some vehicles, there may be a channel for wiring at this location. For remote control radios, a sheet of 1/2 in. plywood one or two inches larger than the radio, is a good method to mount the transceiver to the shelf. It provides a good mounting surface, some shock and vibration isolation, and it keeps moisture away from the radio. Mounting on the floor of the trunk is not recommended. To conserve trunk space, in some vehicles, the radio may be mounted to the rear compartment panel. Locate as far as possible from any vehicle electronic modules located in the rear of the vehicle. In any case, provide good air circulation; a 50 watt RF output FM transmitter will dissipate about 22 watts (@70% efficiency). Do not pile things on top of the unit. 5. TRANSMISSION LINE The transmission line (coaxial cable) should be treated in the same way as the control and power cables. Route flat along body sheet metal wherever possible to avoid sharp edges and pinches. If it is necessary to cross over wiring, cross at right angles. In some cases, additional shielding between the transmission line and the vehicle wiring may be helpful. It is important to maintain the maximum spacing from the vehicle harnesses, especially if the antenna is not a good match. Use the best cable available (98-99% braid coverage or braid/foil) especially at UHF and above. Mechanical pressure on the cable can cause degradation or even short circuits. Do not rely on the obsolete military "RG" designations as an indicator of quality. Cut off, do not coil excess transmission line (This forms a choke balun.) and terminate in the correct connector. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Cellular Phone > Component Information > Technical Service Bulletins > Radio Communication Equipment - Recommendations > Page 5507 The use of N, BNC or C connectors is recommended over "UHF" (PL-259/S0-239) connectors. A small amount of silicone dielectric grease (not the white heat sink compound) in the connector (after soldering) will minimize condensation problems. Cut the line as short as practical, to minimize losses. 6. ANTENNA LOCATION Antenna location is the most important consideration in any mobile installation. For VHF and UHF antennas the recommended place on almost all vehicles is in the center of the roof. The center of the deck lid is an acceptable alternate. Glass-mounted antennas should be mounted at the very top edge of the clear portion of the glass away from the heater grid. Vehicles with printed-on-glass antennas may be damaged by through-glass installations. For HF antennas, refer to the manufacturer's instructions and follow them closely, unless you are an accomplished antenna experimenter. HF antennas should be mounted to body or frame steel for a good counterpoise as well as structural strength. Aluminum bumpers are heavily anodized for corrosion protection, and the coating (aluminum oxide) is very hard as well as nonconductive. A small grinder with a coarse stone will break through the anodized coating for electrical connection. 7. ANTENNA INSTALLATION Permanently installed antennas are preferable over magnetic, glass or body-lip mounts for anything other than for low power or temporary installations. Most of these alternate antennas will reflect some power back at the feedpoint. Much of this will be radiated from the feedline inside the passenger compartment, and may be picked up by the vehicle wiring. For deck lid installations, the deck lid must be bonded to the body, across the hinges, with short, wide tinned braid straps. They must connect to clean sheet metal at both ends. For AM/SSB and even some FM installations, the hood must be bonded to the body. In some cases the doors may need to be bonded, as well. Glass-mount antennas will not work or will only work very poorly in vehicles with metallized glass (Electrically-heated windshields or some solar reflective glass). Non-metallic bodies (e.g., Viper) require a half-wavelength antenna or a ground plane with radius approximately equal to the length of a quarter-wave antenna. Copper is the best choice, but aluminum or even steel may be used. Install on the inside of the body panel with a good adhesive or tape and provide a good RF connection to the coax shield at the feedpoint. Screen, mesh or thin sheet stock may be used. Shape is not critical, but some directional characteristics may be noted if it is not round. Try to stay one-quarter wavelength away from edges, including sunroof openings. Consider the sunroof mechanism for interference to the base and to the feedline. For VHF and UHF, a good quality "NMO" (New Motorola) base or other mount with feedline (center conductor and shield) soldered to base is recommended. This will allow the maximum flexibility in antenna selection and is the best choice for electrical and mechanical considerations. Use the proper hole saw (3/4 in. for NMO) or have it done professionally if you are not comfortable with power tools. Hole plugs are available, for use at sale or trade-in, if you expect to remove the antenna base. To install the antenna base in the hole, remove the one or two-door trim pieces at the pillar where the cable is to be routed and ease the headliner away from the roof. Insert a piece of flat steel or plastic banding (1/2 in. to 3/4 in. wide) and guide to the desired corner. Pull the banding through, leaving 6 in., which can be taped, to the transmission line (easier without the connector, but possible even with a PL-259). Continue pulling until the antenna base is one inch or less from the hole, then seat the base and screw on the outside ring, 0-ring down. A little silicone grease helps maintain a good seal for the life of the vehicle. Tighten with an open-end wrench, and apply a small amount of silicone grease to the contact and insulator surface of the base. This will help exclude water, but must be renewed periodically. Tip: if you remove your antenna to go through the car wash, there are caps available to exclude water during the process. In most vehicles, RG-58-sized cable will fit between the pillar trim and body sheet metal. If necessary, the technique used on the roof can also be used to snake the cable down the inside the pillar. Install the connector very carefully. There are good instructions in The ARRL Handbook. Use a clean, hot, high-wattage iron and work quickly, to prevent damage to the cable dielectric. If you are a beginner or are not comfortable with this kind of detail work, ask for help. It is extremely important.

It is being provided with this Technical Service Bulletin to assist in properly installing communication equipment in DaimlerChrysler vehicles. This information should be given to any owner inquiring about installing radio-transmitting equipment. Installation Recommendations DaimlerChrysler Radio Communication Equipment Installation Recommendations Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Citizens Band Radio (CB) > Component Information > Technical Service Bulletins > Radio Communication Equipment - Recommendations > Page 5512 The following is excerpted from the owners manual of new DaimlerChrysler products: "INSTALLATION OF RADIO TRANSMITTING EQUIPMENT Special design considerations are incorporated into this vehicle's electronic system to provide immunity to radio frequency signals. Mobile two-way radio and telephone equipment must be installed properly by trained personnel. The following must be observed during installation. The positive power connection should be made directly to the battery and fused as close to the battery as possible. The negative power connection should be made to body sheet metal adjacent to the negative battery connection. This connection should not be fused. Antennas for two-way radios should be mounted on the roof or the rear area of the vehicle. Care should be used in mounting antennas with magnet bases. Magnets may affect the accuracy or operation of the compass on vehicles so equipped. The antenna cable should be as short as practical and routed away from the vehicle wiring when possible. Use only fully shielded coaxial cable. Carefully match the antenna and cable to the radio to ensure a low Standing Wave Ratio (SWR). Mobile radio equipment with output power greater than normal may require special precautions. All installations should be checked for possible interference between the communications equipment and the vehicle's electronic systems. A Technical Service Bulletin (TSB) is available for detailed assistance." The owner's first line of contact regarding vehicle problems is the dealer. The literature supplied with each vehicle lists the steps to be taken in the event the dealer is unable to resolve the problem. To assist in properly installing communications equipment in DaimlerChrysler vehicles, the following information is provided. Always use good construction practices (see The ARRL Handbook or other standard reference works). The information contained in this guide has been prepared for use by persons installing two-way radio equipment (transmitters and receivers) in vehicles. It has been prepared in accordance with current engineering principles and generally accepted practices, using the best information available at the time of publication. It is not possible to cover all of the possible installations of two-way radio equipment in this guide. Accordingly, DaimlerChrysler Corporation cannot be held responsible for incidental or consequent damages arising out of the use of the information contained herein. The responsibility for installations and modifications is the sole responsibility of the customer. The installation recommendations presented here are intended to supplement the radio manufacturer's instructions. Test the entire installation for anomalies, especially drivetrain and brake control before extensive driving. 1. CONTROLS Mount the transceiver to a solid surface. If you use screws through the floor pan, put body sealer over the underbody projections. (Stamped acorn nuts, filled with sealer are available at most body shops for this purpose.) This will keep moisture out of the carpet and insulation, and will forestall rust in this area. Watch out for wire harnesses routed under carpet and behind instrument panel. If you mount the radio under the instrument panel, be sure that there is no interference with proper operation of the foot controls. Mount the control head or front panel (especially the microphone cable) so that it is clear of the steering wheel and column controls and passenger airbag. If the unit is heavy, extra bracing may be needed for stability. Newer vehicles have more structure and energy absorbing materials in the knee blocker (the lower part of the Instrument Panel). For one-piece transceivers, if ignition switch control is desired, it is good practice to use a power relay to avoid overloading the ignition switch, and to maintain the advantages of direct battery feed. Try the installation out before you start drilling holes. 2. POWER WIRING To reduce the hazard of working on the vehicle, disconnect the battery NEGATIVE before beginning work. Note that some components may lose short-term memory (e.g.: radio presets) after a protracted time without battery power. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Citizens Band Radio (CB) > Component Information > Technical Service Bulletins > Radio Communication Equipment - Recommendations > Page 5513 For low or medium power transmitters (up to 55W FM or 110W SSB or CW), the power outlet or cigar lighter feed may be used. Use a 1/4" jumper terminal at the socket or splice (solder and heat shrink or tape). For higher power transmitters, including amplifiers, connect the power (battery +) lead at the battery or at the power distribution center or at the positive jump-start post, if the vehicle has one. An appropriate terminal should be used. If the terminal is exposed to the weather, solder and apply a commercial protectant (wheel bearing grease is an acceptable alternative.) to retard corrosion. This lead should be fused as close to the battery as practical to protect the wiring (and the vehicle)! If the power connection is underhood, use a weatherproof fuse holder. Motorola Communications Division supplies a weatherproof holder, part number 09-84277B01 for 5AG cartridge fuses that is part of their standard installation kit. Packard Electric Division of Delphi Automotive Systems makes an insulator, part number 12033769, terminal number 12020156 with cover 12033731 for standard SAE plastic fuses. Vinyl-insulated wire, typically supplied with transceivers is not entirely suitable for the higher underhood temperatures in modern vehicles. Route underhood wiring away from all hot areas. Body sheet metal, away from the exhaust, radiator, A/C liquid line and engine is usually the coolest location. DO NOT FUSE THE GROUND LEAD. If the ground-side fuse were to open, the entire supply current would be conducted by an alternate current return path, which could cause the feedline to overheat, with possible resulting damage. For low or medium power installations, connect the ground (battery -) to body sheet near the power feed point. If you use a screw through the floor, put body sealer over the underbody projection. (Stamped acorn nuts, filled with sealer are available at most body shops for this purpose.) For high power installations, connect the ground (battery -) lead at the battery connection to the body. This is usually a 6 or 8 AWG black wire from the battery negative terminal to a screw at the wheelhouse or radiator support. If a separate sheet metal ground is used, clean the paint off a one inch or so diameter area of body panel where the ground lead is to be connected (usually the case with commercial trunk mount radios). An awl is the best tool to use to pierce a starting hole for a #12 or 5mm, minimum plated ground screw. A ring terminal with lockwasher serrations of the proper size for the screw or a separate serrated (not a split or SAE) lockwasher should be used between the terminal and the screw head. As above, some grease or protectant should be used if the connection is in an unprotected area. If the power cable must pass through the dash panel, try to find an existing hole with a grommet that is unused. If none is available, pull the carpet back from under the dash panel in the passenger footwell in the cabin. Locate a place where there are no other components on either side, as high up as possible. An awl is the best tool to use to punch a small hole through to the engine compartment. If the position is good, enlarge the hole by driving the awl in up to the shank. If this is not large enough to easily pass the cable, enlarge it by using a larger tapered punch. This will leave an extruded hole with no sharp edges. Install the cable and seal the hole with silicone RTV or commercial body sealer on both sides. Seal any extra holes that you may have made. Dress the underhood wiring so that it is sate from all hazards, which include the following: exhaust manifold, steering shaft, throttle linkage, fans, etc. Tie wrap as required. 3. CABLING Route control cables under the floor mats, inside the corner where the floor pan meets the rocker panel for best protection. Remove the sill plates and tuck the cable under the floor mats or carpet and padding. For most left hand drive vehicles, use the right side for best separation to the main body harness (usually on the left side). Route the cable along the extreme outboard edge of the floor pan, under the side trim, if possible. 4. REMOTE TRANSCEIVER For trunk mount installations in passenger cars, you may need to remove the rear seat cushion and seat back to get the cable into the trunk. The seat cushion is usually clipped at the front, lower edge by its own frame: push down and back, then lift. Note the front and rear clipping points for ease of reinstallation. The seat back is usually clipped to the rear compartment inner panel: pull out at the bottom and slide up to remove. Again, note the clipping points for ease of reinstallation. There is usually a vapor/sound barrier behind the seat back, which must be pierced to pass the cable. Open the trunk and pick a spot where the cable is safe from chafing on any sharp sheet metal.

The door for the garage door opener compartment features a spring-loaded latch mechanism and has a small depression with tactile ribs just forward of the latch. The transmitter is mounted within the compartment with an adhesive-backed hook and loop fastener patch and, when the compartment is closed, the depressed area of the compartment door is pressed upward to actuate the transmitter. A transmitter mounting kit including the adhesive backed hook and loop fastener material and additional adapter pegs is available for service. The garage door opener storage bin door is also available for service replacement. The door unit includes the spring-loaded latch mechanism. If any of these components is damaged or faulty, the garage door opener storage bin door unit must be replaced. OPERATION The garage door opener storage compartment door is opened by pressing the spring-loaded latch towards the front of the vehicle. When the compartment door is opened, the garage door opener transmitter can be installed in the compartment using the adhesive-backed hook and loop fastener material provided. With the transmitter mounted in the storage bin, adapter pegs located on the inside of the garage door opener door are selected and mounted on one of several posts on the back side of the door. The adapter pegs can be stacked if additional length is required. The combination of the adapter peg length and the peg location selected must be suitable to depress the button of the transmitter when the center of the garage door opener storage bin door is depressed. When the proper combination has been selected, the compartment door is closed and need not be reopened except to replace the transmitter batteries.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5598 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5599 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5600 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5601 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Towing / Trailer System > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5602 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5625 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5626 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5627 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5628 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5629 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Accessories and Optional Equipment > Trailer Connector > Component Information > Diagrams > Diagram Information and Instructions > Page 5630 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System Central Timer Module ( CTM ) High Option: Description and Operation Airbag System AIRBAG SYSTEM The airbag system is designed to provide increased driver and passenger protection if the vehicle is involved in a front end collision. The system is most effective when used in conjunction with the seat belt system. The airbag control module (ACM) is an electronic module that monitors the airbag system for proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and contains the sensor and actuator that is responsible for airbag deployment. There are no external impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck at the bottom of the instrument panel. It is located forward of the console. The ACM provides diagnostic information (DTCs) to the technician through the DRB III(R) via the CCD bus.Some circuits are tested continuously; others are checked only under certain circumstances. The warning lamp is driven with messages relayed to the Mechanical Instrument Cluster (MIC) from the ACM via the CCD bus. The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be observed by the customer. Whenever the ignition key is turned to the "run" or "start" position,the airbag control module performs a lamp check by turning the AIRBAG warning lamp on for 6 - 8 seconds. If the lamp remains off, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains on, there could be an active fault in the system or the circuit that operates the lamp may be shorted to ground. If the lamp comes on and stays on for a period longer than 6-8 seconds, then goes off, there is usually an intermittent problem in the system. Perform the WARNING LAMP CIRCUIT OPEN procedure (refer to Testing and Inspection in this section) to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 5653 Central Timer Module ( CTM ) High Option: Description and Operation Interior Lighting INTERIOR LIGHTING The courtesy lights are controlled by the CTM. The door switches are inputs to the CTM and the courtesy lights are outputs. The glove box lamp and the ash receiver lamp (if equipped) are not controlled by the CTM. They are hardwired to individual switches and fuses. The highline CTM also provides for illuminated entry option. If the CTM detects an unlock signal from the RKE transmitter, a door disarm switch input or the door jamb switch input, the interior courtesy lights will be turned on. The illuminated entry function is canceled if the CTM senses an ignition "on" condition or the "lock" command from a valid key fob If a door is left open or turned on by rotation of dimmer switch for more than fifteen minutes, the CTM will extinguish the lamps to avoid discharging the battery. If the lamps are turned on by courtesy lamp switch, the CTM will not be able to turn them off. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 5654 Central Timer Module ( CTM ) High Option: Description and Operation Central Timer Module CENTRAL TIMER MODULE The Dakota (AN) utilizes a Central Timer Module (CTM). This system is available in a Base or Highline configuration. The Base CTM does not communicate on the CCD bus and will not be addressed.

The Highline CTM provides the following features: Remote Keyless Entry (RKE) - Chime - Courtesy Lamp Controls/Illuminated Entry - Power Door Locks - Speed Sensitive Intermittent Wipers - Enhanced Accident Response - Vehicle Theft Security System (VTSS) The module is located on the right side of the glove box behind a metal bracket. It contains a white 18-way and a green 14-way connector. CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODES Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure DESCRIPTION Two versions of the Central Timer Module (CTM) are available on this vehicle, a base version and a high-line version. The base version of the CTM is used on base models of the vehicle. The base version of the CTM combines the functions of a chime/buzzer module, an intermittent wipe module, and an ignition lamp time delay relay in a single unit. The high-line version of the CTM is used on highline vehicles. The high-line CTM provides all of the functions of the base version CTM, but also is used to control and integrate many of the additional electronic functions and features included on the high-line models. The high-line version of the CTM contains a central processing unit and interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, reduce internal controller hardware, and reduce component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many new feature capabilities. One of the functions and features that both versions of the CTM support is the chime warning system. The CTM contains a chime tone generator to perform the functions of the chime warning module. The CTM uses hard-wired switch inputs, internal programming, and a hard-wired chime request input from the instrument cluster circuitry to detect when a chime tone is required. Both versions of the CTM are mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening. For diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or the CCD data bus, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. The high-line Central Timer Module (CTM) can also control some features of the audio system when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless entry module, and a vehicle theft security system module in a single unit. The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The RAZ radio receiver with a remote radio switch option is one of the features that the CTM controls. The CTM is programmed to send switch status messages over the Chrysler Collision Detection (CCD) data bus to control the volume, seek, and pre-set station advance functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch status messages to the radio receiver. The electronic circuitry within the radio receiver responds to the switch status messages it receives by adjusting the radio settings as requested. Refer to Remote Radio Switch in the Description and Operation for more information on this component. In addition, radio receivers connected to the CCD data bus have several audio system functions that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more information on DRB testing of the audio systems. The high-line Central Timer Module (CTM) can also operate the horn system. A high-line CTM is used on high-line versions of this vehicle.

The high-line CTM also controls and integrates many of the additional electronic functions and features included on models with this option. The horn relay is one of the hard wired outputs of the CTM. The high-line CTM is programmed to energize or deenergize the horn relay in response to certain inputs from the Remote Keyless Entry (RKE) system and/or the Vehicle Theft Security System (VTSS). Refer to Remote Keyless Entry System Description. Refer to Vehicle Theft Security System Description for more information on the VTSS. Both the base and the high-line versions of the CTM support the intermittent wipe and wipe-after-wash features, but only the high-line CTM supports the speed sensitive intermittent wipe. The intermittent wipe relay is one of the outputs that both the base and the high-line versions of the CTM can control. Each CTM is programmed to energize or de-energize the intermittent wipe relay in response to certain inputs from the windshield wiper and washer switches and from the windshield wiper motor park switch. For the speed sensitive intermittent wipe feature, the high-line CTM also uses vehicle speed messages, which are received on the CCD data bus from the Powertrain Control Module (PCM). The high-line CTM controls features and functions of the power lock, illuminated entry, and Remote Keyless Entry (RKE) systems. The high-line CTM receives hard-wired inputs from the power lock switches, CCD message inputs from the Powertrain Control Module (PCM) and Airbag Control Module (ACM), and coded radio frequency inputs from the RKE transmitters. In response to those and many other inputs, the internal programming of the CTM sends the proper outputs to control the power lock motors, the headlamp and horn relays, and the courtesy lamps. Some of the features and functions of the power lock, illuminated entry and RKE systems made possible because of the communication of the CTM on the CCD data bus network include: A door-lock inhibit feature which prevents the power lock system from being energized with a power door lock switch while the driver door is open if the key is in the ignition and/or the headlamps are on. However, the locks can still be operated manually, with a key, or energized with the RKE transmitter. - A Panic Mode feature which can provide additional personal security and protection. When the Panic button on the RKE transmitter is depressed the vehicle horn will pulse, the headlights will flash, and the interior lights will illuminate on the vehicle for about three minutes, or until the Panic button is depressed a second time. A vehicle speed of about 24 kilometers-per-hour (15 miles-per-hour) will also cancel the panic mode. - An enhanced accident response feature will unlock both doors, then prevent the power door locks from locking the doors for a predetermined time interval, after receiving a CCD message from the ACM indicating a frontal impact of the vehicle requiring airbag deployment. This feature will also turn on the courtesy lamps ten seconds after receiving the ACM deployment message, if the CCD vehicle speed message from the PCM indicates that the vehicle is not moving. Of course, these responses are dependent upon functional battery power and wiring circuitry following the impact. - Rolling door locks is a programmable feature of the power lock system. This feature will automatically lock all of the doors after the vehicle reaches a speed of about 24 kilometers-per-hour (15 miles-per-hour) or greater. This feature will also lock the doors if a door is opened, then closed again, at any speed above 24 kilometers-per-hour (15 miles-per-hour). - A programmable feature of the RKE system is the enabling or disabling of the horn chirp following activation of the RKE Lock function. This feature can be enabled or disabled and, if enabled, the horn chirp duration (twenty or forty milliseconds) can be selected. One of the features that the high-line CTM supports and controls is the Vehicle Theft Security System (VTSS). In the VTSS, the CTM receives hard- wired inputs from the door jamb, door lock cylinder, and ignition switches. The programming in the CTM allows it to process the information from these inputs and send control outputs to energize or de-energize the headlamp relay, horn relay, and the security lamp. The CTM also sends CCD data bus messages to the Powertrain Control Module (PCM) to control the engine no-run feature of the VTSS. The high-line CTM also contains the receiver and control logic for the power lock and Remote Keyless Entry (RKE) systems, which are integrated into the arming, disarming, and triggering functions of the VTSS. The programmable features of the CTM can be enabled or disabled using the DRB scan tool as described in the proper Diagnostic Procedures. Refer to Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the highline version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended. The CTM cannot be repaired and, if faulty or damaged, it must be replaced. This information covers the diagnosis and service of only the hard-wired inputs used by the CTM to determine that a chime tone should be generated. See Central Timer Module in the Diagnosis and Testing for diagnosis of the base version of the CTM. For diagnosis of the high-line version of the CTM or of the CCD data bus, a DRB scan tool and the proper Diagnostic Procedures are recommended.

The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 +12 chimes per minute for reminders and High; 180 + 12 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: Ignition off, key in ignition, driver's door open - Ignition off, headlamps on, driver's door open - Seat belt warning - Check engine lamp illuminated (after prove-out) - Airbag lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out if equipped) - Check gauges lamp illuminated - Low fuel warning lamp illuminated - Low washer fluid Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 5658 Central Timer Module ( CTM ) High Option: Description and Operation Airbag System AIRBAG SYSTEM The airbag system is designed to provide increased driver and passenger protection if the vehicle is involved in a front end collision. The system is most effective when used in conjunction with the seat belt system. The airbag control module (ACM) is an electronic module that monitors the airbag system for proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and contains the sensor and actuator that is responsible for airbag deployment. There are no external impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck at the bottom of the instrument panel. It is located forward of the console. The ACM provides diagnostic information (DTCs) to the technician through the DRB III(R) via the CCD bus.Some circuits are tested continuously; others are checked only under certain circumstances. The warning lamp is driven with messages relayed to the Mechanical Instrument Cluster (MIC) from the ACM via the CCD bus. The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be observed by the customer. Whenever the ignition key is turned to the "run" or "start" position,the airbag control module performs a lamp check by turning the AIRBAG warning lamp on for 6 - 8 seconds. If the lamp remains off, it means that the ACM has checked the system and found it to be free of discernible malfunctions. If the lamp remains on, there could be an active fault in the system or the circuit that operates the lamp may be shorted to ground. If the lamp comes on and stays on for a period longer than 6-8 seconds, then goes off, there is usually an intermittent problem in the system. Perform the WARNING LAMP CIRCUIT OPEN procedure (refer to Testing and Inspection in this section) to find the cause of any customer complaint regarding the AIRBAG warning lamp, such as: warning lamp does not illuminate - warning lamp stays illuminated WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND REPLACED WITH A NEW UNIT. Interior Lighting INTERIOR LIGHTING The courtesy lights are controlled by the CTM. The door switches are inputs to the CTM and the courtesy lights are outputs. The glove box lamp and the ash receiver lamp (if equipped) are not controlled by the CTM. They are hardwired to individual switches and fuses. The highline CTM also provides for illuminated entry option. If the CTM detects an unlock signal from the RKE transmitter, a door disarm switch input or the door jamb switch input, the interior courtesy lights will be turned on. The illuminated entry function is canceled if the CTM senses an ignition "on" condition or the "lock" command from a valid key fob If a door is left open or turned on by rotation of dimmer switch for more than fifteen minutes, the CTM will extinguish the lamps to avoid discharging the battery. If the lamps are turned on by courtesy lamp switch, the CTM will not be able to turn them off. Central Timer Module CENTRAL TIMER MODULE The Dakota (AN) utilizes a Central Timer Module (CTM).

Press F4 when done noting information. DRB III(R) does not power up (Blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRB may be the result of faulty cable or vehicle wiring. Perform the "Blank Screen" test under Testing and Inspection, Non-Diagnostic Trouble Codes in this section. Display is not visible Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition. Enhanced Accident Response (Highline CTM Only) ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY) If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The interior lights will be turned on when the vehicle speed message on the CCD bus indicates 0 mph or the message is not present. In addition to unlocking the doors, the door lock feature will be disabled for a predetermined amount of time following the deployment. Once the ignition key has been cycled to the "off" position, normal operation will resume. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 5663 Glossary of Terms/Acronyms GLOSSARY OF ACRONYMS ACM airbag control module CCD Chrysler Collision Detection (vehicle communication bus) DAB driver airbag DLC data link connector EM entry module PAB passenger airbag PCM powertrain control module PDC power distribution center SQUIB also called indicator (located in rear of airbag module) Mechanical Instrument Cluster (MIC) MECHANICAL INSTRUMENT CLUSTER (MIC) The MIC is available in 4 different versions. Two of the versions are Canadian clusters. There is a highline and a low line cluster available. The difference is the addition of a tachometer in the highline. In order to accomplish this, the fuel level gauge is reduced in size and oil pressure gauge is relocated. The cluster positions it's gauges with bus messages received from the PCM. The odometer is a Liquid Crystal Display (LCD). The cluster will provide bus bias and the PCM provides termination. The MIC has an internal diagnostic routing that can be accessed by pushing and holding the trip odometer while rotating the key to the on position. The cluster will then place all the gauges at their calibration points and will light all the CCD driven tell-tales. It will also light all the segments of the LCD display for a visual verification check. The MIC can verify communications with the PCM, ID the module, or change the country code by using options 1, 3, or 9 on the DRB III(R) under the MIC menu. If there are faults found during the diagnostic routine, the cluster will report them on the LCD odometer display. For further information about the diagnostic routine and the explanation of the faults, please refer to Instrument Panel, Testing and Inspection. Power Door Lock System POWER DOOR LOCKS The CTM controls the door lock actuator assemblies to handle locking and unlocking with the key fob or interior switch. There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is off, the door is open, and the key is in the ignition. Automatic or "rolling locks" are included as a DRB III(R) or customer programmable feature. If the vehicle is moving approximately 15 mph and approximately 10 degrees of throttle opening is seen by the PCM, (the PCM will send this info to the CTM via the CCD bus) indicating acceleration, the CTM will cycle the lock actuators to lock the doors. Remote Keyless Entry (RKE) /Vehicle Theft Security System (VTSS) RKE/VTSS If the vehicle is equipped with Remote Keyless Entry (RKE), programming of additional transmitters and horn chirp are customer programmable features. The highline CTM provides for RKE and the Vehicle Theft Security System (VTSS). The base CTM is not able to provide these functions. The presence of either of these options dictates that the vehicle is equipped with a highline CTM. The VTSS system monitors the door ajar switches and ignition switch to detect unauthorized entry into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to start the engine, it will start and stall, If the trigger condition is still present, the lights will continue to flash for an additional 15 minutes After 15 minutes the system will stop pulsing the lights and return to the "armed" state.The cause of the last 4 alarm triggers is stored by the CTM and may be retrieved by the DRB III(R).The system may be disarmed by either an unlock command from a valid RKE key fob or by using a key in either door. Both front door key cylinders are equipped with disarm switches. There is also a VTSS lamp on the dash that provides information to the driver about the state of the vehicle theft system. The RKE system is placed in the programming mode by the DRB III(R), or by using the customer programming sequence. The system will store up to four key fob codes. Two fobs are supplied with the truck, additional fobs may be purchased through parts department. The additional fobs can be programmed with the DRB III(R), or by using the customer programming sequence. Through the DRB III(R), erasing and programming of one key fob without deleting the others is possible. If the key fob is stolen, all the fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense of security.

There are two additional modules, the Powertrain Control Module (PCM) and the Controller Anti-Lock Brake (CAB) that are not part of the body system, but do utilize the CCD bus for communication. The CAB also utilizes the bus for diagnostics. The PCM sends and receives messages on the CCD bus, however diagnostics are performed through the Serial Communication Interface of SCI, the same as previous years. All of the information about the functioning of all the systems is organized controlled, and communicated by the CCD bus, which is described in (CCD Bus) of this general information. Through the CCD bus, information about the operation of vehicle components and circuits is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require all the information to perform it's function. It will only respond to messages "addressed" to it through a binary coding process. This method of data transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. Airbag Trouble Code Types and Descriptions AIRBAG DIAGNOSTIC TROUBLE CODES Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists,diagnostic priority should be given to the active codes. Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic test procedures contain step-by-step instructions for determining the cause of the trouble codes. It is not necessary to perform all of the tests in this book to diagnose an individual code. Always begin by reading the diagnostic trouble codes using the DRB, The procedure begins with AIRBAG TEST 1A-Identifying Airbag System Problems. This will direct you to the specific test(s) that must be performed. Active diagnostic trouble codes for the airbag system are not permanent and will change the moment the reason for the code is corrected. In certain test procedures, diagnostic trouble codes are used as a diagnostic tool. Active Codes The code becomes active as soon as the malfunction is detected and stored after one minutes of occurrence or key-off, whichever occurs first. An active trouble code indicates an on-going malfunction. This means that the defect is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected. With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present. Stored Codes Airbag codes are automatically stored in the ACM's memory after one minute of occurrence or when the ignition is turned off. The exception is the "Loss of Ignition Run Only" code which is an active code only. A "stored" code indicates there was an active code present at some time. However, the code currently may not be present as an active code, although another active code could be. When a trouble code occurs, the airbag warning lamp illuminates for 12 seconds minimum (even if the problem existed for less than 12 seconds). The code is stored, along with the time in minutes it was active, and the number of times the ignition has been cycled since the problem was last detected. The minimum time shown for any code will be one minute, even if the code was actually present for less than one minute. Thus, the time shown for a code that was present for two minutes 13 seconds, for example, would be three minutes. If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same malfunction, the diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset and the diagnostic trouble code will continue to be a stored code. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 5665 If a malfunction is not active while performing a diagnostic test procedure, the active code diagnostic test will not locate the source of the problem. In this case, the stored code can indicate an area to inspect. If no obvious problems are found, erase stored codes, and with the "on" wiggle the wire harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes periodically as you work through the system. This procedure may uncover a malfunction that is difficult to locate. Airbag Diagnostic Trouble Codes The airbag control module may report any of the following diagnostic trouble codes. For the following codes, replace the Airbag Control Module (ACM) even if set intermittently: ACM Accelerometer - Internal Diagnostic 1 - Internal Diagnostic 2 For the following codes, replace the airbag control module (ACM): ACM Output Driver - ACM Stored Energy Logic - ACM Stored Energy Driver - ACM Stored Energy Passenger - Internal Diagnostic 3 - Internal Diagnostic 4 - Safing Sensor Shorted - Warning Lamp Driver Error For these codes, refer to the appropriate diagnostic procedure: Driver Squib Open Driver Squib Shorted Loss of Ignition Run Only Loss of Ignition Run/Start No CCD Communication Passenger Squib Circuit Open Passenger Squib Circuit Shorted Either Squib Terminal Short to Battery Either Squib Terminal Short to Ground Warning Lamp Circuit Open Warning Lamp Circuit Shorted Central Timer Module Diagnostic Trouble Codes CENTRAL TIMER MODULE DIAGNOSTIC TROUBLE CODES Door Disarm Switch Failure Door Lock Switch Failure Door Unlock Switch Failure Wiper Park Switch Failure EEPROM Checksum Failure Internal ROM Test Failure Vehicle Communication VEHICLE COMMUNICATION The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another. They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has the highest priority, and is then allowed to access the bus first. The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus -" (bus minus) respectively. Each wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for the coded messages, there is a "voltage divider network" located in the module that supplies bus bias or voltage. Along with the module that supplies bias, some modules provide termination. Bias is the voltage necessary to make the bus operational. At least one point of termination is necessary, some systems may use more than one. Some modules are capable of both biasing and terminating. Termination in the circuitry (a 120 ohm resistor placed across the bus) is required to complete the voltage divider network circuit and also provide some electromagnetic protection for the bus. In this vehicle, the bias is supplied by the instrument cluster and termination is provided by the PCM and the instrument cluster. Without termination,voltage on the bus goes to approximately 5 volts on one wire and 0 volts on the other wire. NOTE: COMMUNICATION OVER THE BUS IS ESSENTIAL TO THE PROPER OPERATION OF THE VEHICLE'S ON-BOARD Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Description and Operation > Airbag System > Page 5666 DIAGNOSTIC SYSTEMS AND THE DRB. PROBLEMS WITH THE OPERATION OF THE BUS OR DRB MUST BE CORRECTED BEFORE PROCEEDING WITH DIAGNOSTIC TESTING. IF THERE IS A PROBLEM, REFER TO TESTING AND INSPECTION IN THIS SECTION. BUS FAILURE MESSAGES Short to Battery - Either or both of the bus wires are shorted to the battery potential. Or open ground to any CCD bus module. Short to 5 Volts - Either or both of the bus wires are shorted to a 5 volt potential. Short to Ground - Either or both of the bus wires are shorted to ground. Bus (+) & (-) Shorted Together - The two bus wires are shorted together. No Termination - The bus system has lost connection with all of its terminators. Bus Bias Level Too Low - Either or both of the bus wire potentials are significantly below their normal 2.5 volts. Bus Bias Level Too High - Either or both of the bus wire potentials are significantly above their normal 2.5 volts. No Bus Bias - The bus system has lost connection with Instrument Cluster. Bus (+) Open - The bus (+) wire has lost connection with termination and/or bias. Bus (-) Open - The bus (-) wire has lost connection with termination and/or bias. Not Receiving Bus Messages Correctly - The DRB cannot communicate over the bus and does not know why. Warnings WARNINGS Vehicle Damage Warnings Before disconnecting any control module, make sure the ignition is "off". Failure to do so could damage the module. When testing voltage or continuity at any control module, use the terminal side(not the wire end) of the connector. Do not probe a wire through the insulation; this will damage it and eventually cause it to fail because of corrosion. Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of the original problem more difficult. Road testing a complaint vehicle Some of the complaints will require a test drive as part of the repair verification procedure. The purpose of the test drive is to try to duplicate the diagnostic code or symptom condition. CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE REASSEMBLED. DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB SCREEN WHILE IN MOTION. DO NOT HANG THE DRB FROM THE REAR VIEW MIRROR OR OPERATE IT YOURSELF. HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB. Wiper System SPEED SENSITIVE INTERMITTENT WIPERS The AN truck equipped with a highline CTM will utilize speed sensitive intermittent wipers. Only a highline CTM will be able to support this feature. A base CTM will provide for intermittent wipers without the speed sensitive feature. The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, an immediate wipe of the windshield takes place and the new delay interval is implemented. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Body Control Systems > Central Timer Module ( CTM ) High Option <--> [Body Control Module] > Component Information > Testing and Inspection > Reading and Clearing Diagnostic Trouble Codes Central Timer Module ( CTM ) High Option: Reading and Clearing Diagnostic Trouble Codes With Scan Tool Data Link (Diagnostic) Connector Location Technicians must retrieve stored DTC's by connecting the DRB scan tool (or an equivalent scan tool) to the 16-way data link connector.

Press F4 when done noting information. DRB III(R) Does Not Power Up (blank Screen) If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts is required to adequately power the DRB. If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRB may be the result of faulty cable or vehicle wiring. Perform the "Blank Screen" test under Vehicle Communication. Display Is Not Visible Low temperatures will affect the visibility of the display.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Diagram Information and Instructions > Page 5811 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Diagram Information and Instructions > Page 5812 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Diagram Information and Instructions > Page 5813 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Diagram Information and Instructions > Page 5814 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Diagram Information and Instructions > Page 5815 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Diagram Information and Instructions > Page 5816 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Diagram Information and Instructions > Page 5826 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Diagram Information and Instructions > Page 5827 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Page 5828 Console: Application and ID CAUTION: Do not use bulbs that have a higher candle power than the bulb listed in the Bulb Application Table. Damage to lamp can result. Some components have lamps that can only be serviced by an Authorized Service Center (ASC) after the component is removed from the vehicle. Overhead Console = Bulb Number 578 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Page 5829 Console: Description and Operation OVERHEAD CONSOLE SYSTEM An overhead console unit is an available factory-installed option on this model. The overhead console unit features a garage door opener storage bin, a sunglasses storage bin, two reading and courtesy lamps and a compass mini-trip computer. See the owner's manual in the vehicle glove box for more information on the features, use and operation of all of the overhead console components and systems. Overhead Console OVERHEAD CONSOLE The overhead console for this model includes two front-mounted reading and courtesy lamps, a garage door opener storage bin, a sunglasses storage bin and a compass mini-trip computer. The overhead console is secured with two snap clips at the rear and a single screw at the front to the overhead console mounting bracket. The front of the overhead console mounting bracket is secured to the roof header near the windshield with two screws, and the rear of the bracket is secured with double-faced tape to the inside surface of the roof panel. A single electrical connection joins the overhead console wire harness to the roof wire harness. THERMOMETER The thermometer displays the outside ambient temperature in whole degrees. The temperature display can be changed from Fahrenheit to Celsius using the U.S./Metric push button. The displayed temperature is not an instant reading of conditions, but an average temperature. It may take the thermometer display several minutes to respond to a major temperature change, such as driving out of a heated garage into winter temperatures. When the ignition switch is turned to the Off position, the last displayed temperature reading stays in the thermometer unit memory. When the ignition switch is turned to the On position again, the thermometer will display the memory temperature if the engine coolant temperature is above about 52° C (125° F). If the engine coolant temperature is below about 52° C (125° F), the thermometer will display the actual temperature sensed by the ambient temperature sensor. The thermometer temperature display update interval varies with the vehicle speed. The thermometer function is supported by an ambient temperature sensor. The sensor is mounted outside the passenger compartment near the front and center of the vehicle, and is hard wired to the module. The ambient temperature sensor is available as a separate service item. SUNGLASSES STORAGE BIN Description A sunglasses storage bin is included in the overhead console. The storage bin is located near the center of the overhead console and is held in the closed position by a spring-loaded latch mechanism that is integral to the storage bin door. The interior of the bin is lined with a foam rubber padding material to protect the sunglasses from being scratched. A damper spring is snapped onto the pivot shaft of the sunglasses storage bin door. The damper spring engages two flats on the shaft and is anchored in a slot in the rear flange of the overhead console reading and courtesy lamp housing to provide a smooth opening action and an open detent position for the storage bin unit. The sunglasses storage bin and door unit is available for service replacement. The bin and door unit includes the spring-loaded latch mechanism, the bin liner and the damper spring. If any of these components is damaged or faulty, the sunglasses storage bin and door unit must be replaced. Operation The sunglasses storage bin is opened by pressing the latch on the rear edge of the door towards the front of the vehicle, then pulling the bin downward to the open detent position. The spring-loaded latch mechanism on the sunglasses bin door will automatically engage when the bin is Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Console > Component Information > Diagrams > Page 5830 closed.

The PADS is equipped with a key cylinder so that the switch position can only be changed using an ignition key. When the ignition switch is in the On position and the passenger side airbag is disarmed, a Light-Emitting Diode (LED) illuminates an "Off" indicator lamp on the face plate of the switch. To actuate the PADS switch, insert the ignition key in the switch key cylinder. The PADS key cylinder is then rotated with the ignition key to its clockwise stop (the key cylinder slot will be aligned with the Off indicator lamp) to disarm the passenger side airbag. When the PADS key cylinder is rotated with the ignition key to its counterclockwise stop (the key cylinder slot will be in a vertical position), the Off indicator lamp will be extinguished and the passenger side airbag module will once again be armed. WARNING: THE KEY MUST ALWAYS BE REMOVED FROM THE PASSENGER AIRBAG DISARM SWITCH KEY CYLINDER AFTER THE SWITCH HAS BEEN USED. NEVER LEAVE A KEY IN THE PADS KEY CYLINDER. The PADS cannot be adjusted or repaired and, if faulty or damaged, the PADS unit must be replaced. Disarming Both Airbags Disconnect and isolate the battery negative cable. If the airbag has not been deployed, wait two minutes for the system capacitor to discharge before further service. Arming Both Airbags Prior to arming the system verify system operation as follows: A DRB scan tool is required for diagnosis of the airbag system. Refer to the proper Diagnostic Procedures for more information. 16-Way Data Link Connector - Typical 1. Connect the DRB scan tool to the 16-way data link wire harness connector. The connector is located on the driver side lower edge of the instrument panel, outboard of the steering column. 2. Turn the ignition switch to the On position. Exit the vehicle with the DRE. Use the latest version of the proper DRB cartridge. 3.. Using the DRB, read and record the active Diagnostic Trouble Code (DTC) data. 4. Read and record any stored DTC data. 5. Refer to the proper Diagnostic Procedures if any DTC is found in Step 3 or Step 4. 6. Erase the stored DTC data. If any problems remain, the stored DTC data will not erase. 7. With the ignition switch still in the ON position, make sure nobody is in the vehicle. 8. From outside of the vehicle (away from the airbag modules in case of an accidental deployment) turn the ignition switch to the OFF position for about ten seconds, and then back to the ON position. Observe the airbag indicator lamp in the instrument cluster. It should light for six to eight seconds, and then go out. This indicates that the airbag system is functioning normally NOTE: It the airbag indicator lamp fails to light, or lights and stays on, there is an airbag system malfunction. Refer to the proper Diagnostic Procedures to diagnose the problem. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Interior Moulding / Trim > Glove Compartment > Glove Compartment Lock > Component Information > Service and Repair Glove Compartment Lock: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The CTM also contains the program logic and control circuitry for the RKE system. The CTM is mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening. The RKE receiver has a memory function to retain the vehicle access codes of up to four RKE transmitters. The receiver is designed to retain the transmitter codes in memory, even if the battery is disconnected. The RKE receiver is energized by one of three radio frequency inputs from the RKE transmitter; Unlock, Lock, or Panic. The programming of the CTM responds to these RKE inputs, as well as many other inputs, by sending the proper control outputs to the power lock motors, the courtesy lamp circuit, the horn relay, and the headlamp relay. For diagnosis or programming of the RKE receiver within the high-line CTM, a DRB scan tool and the proper Diagnostic Procedures are recommended. The RKE receiver is only serviced as a unit with the high-line CTM and, if faulty or damaged, the CTM unit must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Locks > Keyless Entry > Keyless Entry Transmitter > Keyless Entry Transmitter Battery > Component Information > Service and Repair Keyless Entry Transmitter Battery: Service and Repair The Remote Keyless Entry (RKE) transmitter case snaps open and shut for battery access.

The power lock motor is integral to the door latch mounted within each door. The power lock motor direction is controlled by the battery and ground feeds from the power lock and unlock relays, which are integral to the high-line Central Timer Module (CTM). The power lock motor cannot be repaired and, if faulty or damaged, the entire door latch unit must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Locks > Power Locks > Power Door Lock Actuator > Component Information > Description and Operation > Page 5863 Power Door Lock Actuator: Testing and Inspection Before you proceed with this diagnosis, confirm proper power lock switch, Central Timer Module (CTM) and power lock switch output circuit operation. See Power Door Lock Switch and Central Timer Module for Testing. Remember, the CTM circuitry controls the output to each of the power lock motors. 1. Check each power lock motor for correct operation while moving the power lock switch to both the Lock and Unlock positions. If both of the power lock motors are inoperative, go to Step 2. If one power lock motor is inoperative, go to Step 3. 2. If both of the power lock motors are inoperative, the problem may be caused by one shorted motor. Unplugging a shorted power lock motor from the power lock circuit will allow the good power lock motor to operate. Unplug each power lock motor wire harness connector, one at a time, and recheck both the lock and unlock functions by operating the power lock switch. If both of the power lock motors are still inoperative after the above test, check for a short or open circuit between the power lock motors and the CTM. If unplugging one power lock motor causes the other motor to become functional, go to Step 3 to test the unplugged motor. 3. Once it is determined which power lock motor is inoperative, that motor can be tested as follows. Unplug the wire harness connector at the inoperative power lock motor. Apply 12 volts to the motor terminals to check its operation in one direction. Reverse the polarity to check the operation in the other direction. If OK, repair the short or open circuits between the power lock motor and the CTM as required. If not OK, replace the faulty power lock motor. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Locks > Power Locks > Power Door Lock Actuator > Component Information > Description and Operation > Page 5864 Power Door Lock Actuator: Service and Repair REMOVAL AND INSTALLATION The power lock motor is integral to the door latch unit.

The motors are connected to worm-drive gearboxes that move the seat adjuster through a combination of screw-type drive units. The front and rear of a seat are operated by different motors. They can be raised or lowered independently of each other. When the center seat switch is pushed to the Up or Down position, both the front and rear motors operate in unison, moving the entire seat up or down. The forward-rearward motor is operated by pushing the center seat switch to the Forward or Rearward position. When a switch is actuated, a battery feed and a ground path are applied through the switch contacts to the motor(s). The motor(s) and drives operate to move the seat in the selected direction until the switch is released, or until the travel limit of the power seat adjuster is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor(s) are reversed through the switch contacts. This causes the motor to run in the opposite direction. Each motor contains a self-resetting circuit breaker to protect it from overload. Consecutive or frequent resetting of the circuit breakers must not be allowed to continue, or the motors may be damaged. Make the necessary repairs. The power seat adjuster and motors cannot be repaired, and are serviced only as a complete unit. If any component in this unit is faulty or damaged, the entire power seat adjuster and motors assembly must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Body and Frame > Seats > Power Seat Motor > Component Information > Description and Operation > Page 5896 Power Seat Motor: Testing and Inspection Operate the power seat switch to move all three seat motors in each direction. The seat should move in each of the selected directions. If the power seat adjuster fails to operate in only one direction, move the adjuster a short distance in the opposite direction and test again to be certain that the adjuster is not at its travel limit. If the power seat adjuster still fails to operate in only one direction, see Power Seat Switch in the Diagnosis and Testing. If the power seat adjuster fails to operate in more than one direction, proceed as follows: 1. Test the circuit breaker in the junction block. If OK, go to Step 2. If not OK, replace the faulty circuit breaker. 2. Remove the power seat switch from the seat. Check for battery voltage at the fused B(+) circuit cavity of the power seat switch wire harness connector. If OK, go to Step 3.

The chime system is built into the CTM. The system also supports an external chime request from the instrument cluster. This feature allows the instrument cluster to request a chime from the CTM for seat belt, gauge problems and tell-tale warnings. There are two chime rates, Low; 50 +12 chimes per minute for reminders and High; 180 + 12 chimes per minute for serious conditions that require immediate attention. The high rate chime sounds when the key is left in the ignition and the doors are open or the headlights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate feature that allows the chime to sound continuously for key-in and headlamp warning as long as the door is open. The seat belt warning chime is activated for approximately six seconds, and all other chime conditions will activate the chime once at the same time the warning light on the cluster is illuminated. The chime will sound for the following conditions: - Ignition off, key in ignition, driver's door open - Ignition off, headlamps on, driver's door open - Seat belt warning - Check engine lamp illuminated (after prove-out) - Airbag lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out) - Anti-lock lamp illuminated (after prove-out if equipped) - Check gauges lamp illuminated - Low fuel warning lamp illuminated - Low washer fluid Refer to the owner's manual in the vehicle glove box for more information on the features, use and operation of the chime warning system.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only.

Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6026 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6027 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6028 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6029 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6040 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6041 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6042 Central Timer Module ( CTM ) Low Option: Connector Views Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6043 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6044 Central Timer Module ( CTM ) Low Option: Electrical Diagrams Component Diagrams 8w-45-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6045 8w-45-3 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6046 8w-45-4 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6047 8w-45-5 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6048 8w-45-6 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6049 8w-45-7 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6050 8w-45-8 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6051 8w-45-9 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6052 8w-45-10 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6053 8w-45-11 NOTE: To view sheets referred to in these diagrams, see Complete Body and Chassis Diagrams.

For the RWAL system, the red brake warning lamp also is used to alerts the driver of a problem with the RWAL system. The brake warning lamp illuminates when a message is sent over the bus to the cluster to illuminate the bulb. A ground for the bulb is provided when: The brakes are applied and the park brake switch is actuated. - A hydraulic fault has occurred and the pressure differential switch is actuated. - A RWAL fault has occurred. The lamp is turned on momentarily when the ignition switch is turn to the on position. This is a self test to verify the lamp is operational. ABS WARNING LAMP The amber ABS warning lamp is used to alert the driver of an RWAL problem and identify DTCs stored in the CABs memory. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Description and Operation > With Rear Wheel Antilock Brakes > Page 6066 Brake Warning Indicator: Description and Operation With Four Wheel Antilock Brakes Red Brake Warning Lamp A red warning lamp is used for the service brake portion of the hydraulic system. The lamp is located in the instrument cluster. The red warning light alerts the driver if a pressure differential exists between the front and rear hydraulic systems or the parking brakes are applied. The lamp is turned on momentarily when the ignition switch is turn to the on position. This is a self test to verify the lamp is operational. Amber ABS Warning Lamp The amber ABS warning lamp is located in the instrument cluster. The lamp illuminates at start-up to perform a self check. The lamp goes out when the self check program determines the system is operating normal. If an ABS component exhibits a fault the CAB will illuminate the lamp and register a trouble code in the microprocessor. The lamp is controlled by the CAB. The CAB controls the lamp sending a message to the instrument cluster. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Brake Warning Indicator > Component Information > Description and Operation > Page 6067 Brake Warning Indicator: Testing and Inspection Hard Wired Lamp Diagnosis Each of the lamps found upon a hard wired circuit input to the instrument cluster for proper operation. The following procedures will help to diagnose conditions that may cause an inoperative hard wired lamp circuit condition. WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAG BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY. The diagnosis found here addresses an inoperative brake warning lamp condition. If the brake warning lamp stays on with the ignition switch in the On position and the park brake released, or comes on while driving, refer to Rear Wheel Antilock for vehicles equipped with a rear wheel anti-lock brake system. If no brake system problem is found, the following procedure will help locate a faulty park brake switch or park brake switch sense circuit. 1. Check the fused ignition switch output (run/start) fuse in the junction block. If OK, go to Step 2. If not OK, repair the shorted circuit or component as required and replace the faulty fuse. 2. Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output (run/start) fuse in the junction block. If OK, go to Step 3. If not OK, repair the open fused ignition switch output (run/start) circuit to the ignition switch as required. 3. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the wire harness connector at the park brake switch. With the park brake released, check for continuity between the park brake switch terminal and a good ground. There should be no continuity. If OK, go to Step 4. If not OK, adjust or replace the faulty park brake switch. 4. Remove the instrument cluster. With the park brake switch wire harness connector still disconnected, check for continuity between the park brake switch sense circuit cavity of the park brake switch wire harness connector and a good ground. There should be no continuity. If OK, go to Step 5. If not OK, repair the shorted park brake switch sense circuit as required. 5. Check for continuity between the park brake switch sense circuit cavities of the instrument cluster wire harness connector A and the park brake switch wire harness connector. There should be continuity. If OK, refer to Instrument Cluster Preliminary Diagnosis for further testing of the brake warning lamp and the instrument cluster circuitry. If not OK, repair the open park brake switch sense circuit as required. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Check Gauges Lamp > Component Information > Application and ID Check Gauges Lamp: Application and ID CAUTION: Do not use bulbs that have a higher candle power than the bulb listed in the Bulb Application Table.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 6077 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 6078 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 6079 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 6080 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 6081 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 6082 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 6092 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Diagram Information and Instructions > Page 6093 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Page 6094 Cigarette Lighter: Service Precautions WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIR-BAG BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The cigar lighter is installed in the instrument panel lower bezel, which is located near the center of the instrument panel, below the radio. The cigar lighter base is secured by a snap fit within the instrument panel lower bezel. The cigar lighter knob and heating element unit, and the cigar lighter receptacle unit are available for service. These components cannot be repaired and, if faulty or damaged, they must be replaced. OPERATION The cigar lighter consists of two major components: a knob and heating element unit, and the cigar lighter base or receptacle shell. The receptacle shell is connected to ground, and an insulated contact in the bottom of the shell is connected to battery current. The cigar lighter receives battery voltage from a fuse in the junction block only when the ignition switch is in the Accessory or On positions. The knob and heating element are encased within a spring-loaded housing, which also features a sliding protective heat shield. When the knob and heating element are inserted in the receptacle shell, the heating element resistor coil is grounded through its housing to the receptacle shell. If the cigar lighter knob is pushed inward, the heat shield slides up toward the knob exposing the heating element, and the heating element extends from the housing toward the insulated contact in the bottom of the receptacle shell. Two small spring-clip retainers are located on either side of the insulated contact inside the bottom of the receptacle shell. These clips engage and hold the heating element against the insulated contact long enough for the resistor coil to heat up. When the heating element is engaged with the contact, battery current can flow through the resistor coil to ground, causing the resistor coil to heat. When the resistor coil becomes sufficiently heated, excess heat radiates from the heating element causing the spring-clips to expand. Once the spring-clips expand far enough to release the heating element, the spring-loaded housing forces the knob and heating element to pop back outward to their relaxed position. When the cigar lighter knob and element are pulled out of the receptacle shell, the protective heat shield slides downward on the housing so that the heating element is recessed and shielded around its circumference for safety Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cigarette Lighter > Component Information > Diagrams > Page 6096 Cigarette Lighter: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIR-BAG BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Diagram Information and Instructions > Page 6106 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Diagram Information and Instructions > Page 6107 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Diagram Information and Instructions > Page 6108 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Diagram Information and Instructions > Page 6109 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Diagram Information and Instructions > Page 6110 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Diagram Information and Instructions > Page 6111 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Diagram Information and Instructions > Page 6121 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Diagram Information and Instructions > Page 6122 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Diagram Information and Instructions > Page 6123 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Diagram Information and Instructions > Page 6124 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Page 6125 Compass: Description and Operation COMPASS MINI-TRIP COMPUTER (CMTC) This system, located in the overhead console, displays information on outside temperature, compass direction and trip information. Compass And Temperature Display This display provides the outside temperature and one of eight compass readings to indicate the direction the vehicle is facing. Trip Odometer (ODO) Shows the distance traveled since the last reset. Average Fuel Economy (AVE ECO) Shows the average fuel economy in MPG (miles per gallon) or L/100Km since the last reset. Instantaneous Fuel Economy Shows the fuel economy for the last few seconds in MPG or L/100Km. Distance to Empty (DTE) Shows the estimated distance that can be traveled with the fuel remaining in the tank. This is calibrated using the MPG for the last few minutes. Elapsed Time (ET) Shows the accumulated ignition on time since the last reset. Step Button Press this button to cycle through all the mini-trip computer displays. US/M Button Press this button to convert all vehicle displays from US to Metric to US. To Reset the Display Press the Step and US/M buttons simultaneously for at least two seconds and all resettable conditions will be reset. This will occur only if a resettable function (AVG ECO,Trip Odometer, ET) is currently being displayed. Automatic Compass Calibration This compass is self calibrating which eliminates the need to manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL symbol will be displayed. After completing three 360 degree turns in an area free from large metal or metallic objects, the CAL symbol will turn off and the compass will function normally. Compass Variance Compass Variance is the difference between Magnetic North and Geographic North. In some areas of the country, the difference between Magnetic and Geographic North is great enough to cause the compass to give false readings. If this occurs, the compass variance must be set. To set the variance: Turn the ignition ON and set display to Comp./Temp. While pressing the US/M button, press the STEP button for approximately five seconds. The "VAR" symbol will light and the last variance zone number will be displayed. Press the US/Metric Button to select the proper variance zone as shown on the map. Press the Step button to set the new variance zone and resume normal operation. DESCRIPTION The compass mini-trip computer is located in the overhead console on models equipped with this option. The compass mini-trip computer units include the electronic control module, a Vacuum-Fluorescent Display (VFD), a compass sensor unit and two push button function switches. The compass mini-trip computer module contains a central processing unit and interfaces with other electronic modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, reduce internal controller hardware, and reduce component sensor current loads. At the same time, this system provides increased reliability, enhanced diagnostics, and allows the addition of many new feature capabilities. The compass mini-trip computer provides several electronic functions and features. Some of the functions and features that the compass mini-trip computer module supports and/or controls, include the following display options: Compass and temperature - provides the outside temperature and one of eight compass readings to indicate the direction the vehicle is facing. - Trip odometer (TRIP ODO) - shows the distance travelled since the last trip computer reset. - Average fuel economy (AVG ECO) - shows the average fuel economy since the last trip computer reset. - Instant fuel economy (ECO) - shows the present fuel economy based upon the current vehicle distance and fuel used information. - Distance to empty (DTE) - shows the estimated distance that can be travelled with the fuel remaining in the fuel tank. This estimated distance is computed using the average miles-per-gallon from the last 30 gallons of fuel used. - Elapsed time (ET) - shows the accumulated ignition-on time since the last trip computer reset. - Blank screen - the compass mini-trip VFD is turned off. The ambient temperature sensor is hard wired to the compass mini-trip computer module. Data input for all other compass mini-trip computer functions, including VFD dimming level, is received through CCD data bus messages. The compass mini-trip computer uses its internal Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Page 6126 programming and all of these inputs to calculate and display the requested data. If the data displayed is incorrect, perform the self-diagnostic tests as described. If these tests prove inconclusive, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended for further testing of the compass mini-trip computer module and the CCD data bus. The compass mini-trip computer module cannot be repaired, and is available for service only as a unit. This unit includes the push button switches and the plastic module and display lens. If any of these components is faulty or damaged, the complete compass mini-trip computer module must be replaced. While in the compass/temperature mode, the compass will display the direction in which the vehicle is pointed using the eight major compass headings (Examples: north is N, northeast is NE). The self-calibrating compass unit requires no adjusting in normal use. The only calibration that may prove necessary is to drive the vehicle in three complete circles, on level ground, in not less than forty-eight seconds. This will reorient the compass unit to its vehicle. The compass unit also will compensate for magnetism the body of the vehicle may acquire during normal use. However, avoid placing anything magnetic directly on the roof of the vehicle. Magnetic mounts for an antenna, a repair order hat, or a funeral procession flag can exceed the compensating ability of the compass unit if placed on the roof panel. Magnetic bit drivers used on the fasteners that hold the overhead console assembly to the roof header can also affect compass operation. If the vehicle roof should become magnetized, the demagnetizing and calibration procedures may be required to restore proper compass operation. OPERATION The compass mini-trip computer only operates with the ignition switch in the On position. When the ignition switch is turned to the On position, all of the segments in the compass mini-trip computer VFD will be turned off for one second, then the display will return to the last function being displayed before the ignition was turned to the Off position. With the ignition switch in the On position, momentarily depressing and releasing the Step push button switch will cause the compass-mini-trip computer to change its mode of operation, and momentarily depressing and releasing the U.S./Metric push button will cause the unit to toggle between U.S. and Metric measurements. This compass mini-trip computer features several functions that can be reset. If both the Step and U.S./ Metric push buttons are depressed at the same time for more than one second with the ignition switch in the On position, the trip computer information that can be reset is reset. However, the reset will only occur if the function currently displayed is a function that can be reset. The functions that can be reset are: TRIP ODO, AVG ECO, and ET. For more information on the features and control functions of the compass mini-trip computer, see the owner's manual in the vehicle glove box. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Diagrams > Page 6127 Compass: Testing and Inspection If the problem with the compass mini-trip computer module is an "OC" or "SC" in the compass/thermometer display, refer to Ambient Temperature Sensor in the Diagnosis and Testing. If the problem with the compass mini-trip computer module is an inaccurate or scrambled display, refer to Self-Diagnostic Test in the Diagnosis and Testing. If the problem with the compass mini-trip computer module is incorrect Vacuum Fluorescent Display (VFD) dimming levels, use a DRB scan tool and the proper Diagnostic Procedures to test for the correct dimming message inputs being received from the instrument cluster over the Chrysler Collision Detection (CCD) data bus. If the problem is a no-display condition, use the following procedures. 1. Check the fused ignition switch output (run/ start) fuse in the junction block. If OK, go to Step 2. If not OK, repair the shorted circuit or component as required and replace the faulty fuse. 2. Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output (run/start) fuse in the junction block. If OK, go to Step 3. If not OK, repair the open fused ignition switch output (run/start) circuit to the ignition switch as required. 3. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Remove the overhead console. Check for continuity between the ground circuit cavities of the roof wire harness connector for the overhead console and a good ground. There should be continuity. If OK, go to Step 4. If not OK, repair the open ground circuit to ground as required. 4. Connect the battery negative cable. Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output (run/start) circuit cavity of the roof wire harness connector for the overhead console. If OK, refer to Self-Diagnostic Test in the Diagnosis and Testing for further diagnosis of the compass mini-trip computer module and the CCD data bus. If not OK, repair the open fused ignition switch output (run/ start) circuit to the junction block fuse as required. Self-diagnostic Test A self-diagnostic test is used to determine that the compass mini-trip computer module is operating properly electrically Initiate the self-diagnostic test as follows: 1. With the ignition switch in the Off position, simultaneously depress and hold the Step button and the U.S./Metric button. 2. Turn the ignition switch to the On position. 3. Continue to hold both buttons depressed until the compass mini-trip computer module enters the display segment test. In this test, all of the Vacuum Fluorescent Display (VFD) segments are lighted while the compass mini-trip computer module performs the following checks: a. Microprocessor compass circuit test b. Non-volatile memory read/write test c. Microprocessor ROM verification test d. CCD communications test. 4. Following completion of these tests, the compass mini-trip computer will return to normal operation or display one of two messages: "FAIL" or Respond to these test results as follows: e. If no test result message is displayed, but compass mini-trip computer operation is still improper, the use of a DRB scan tool and the proper Diagnostic Procedures are required for further diagnosis. f. If the "FAIL" message is displayed, the compass mini-trip computer module is faulty and must be replaced. g. If the "CCD" message is displayed, the use of a DRB scan tool and the proper Diagnostic Procedures are required for further diagnosis. h. If any VFD segment should fail to light during the display segment test, the compass mini-trip computer module is faulty and must be replaced. 5. If all tests are passed, or if the ignition switch is turned to the Off position, the compass mini-trip computer module will automatically return to normal operation. NOTE: If the compass functions, but accuracy is suspect, it may be necessary to perform a variation adjustment. This procedure allows the compass unit to accommodate variations in the earth's magnetic field strength, based on geographic location. Refer to Compass/Service and Repair/Variation Adjustment. - If the compass reading has blanked out, and only "CAL" appears in the display, demagnetizing may be necessary to remove excessive residual magnetic fields from the vehicle. Refer to Compass/Service and Repair/Compass Demagnetizing. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Service and Repair > Compass Variation Adjustment Service Compass: Service and Repair Compass Variation Adjustment Service Compass variance, also known as magnetic declination, is the difference in angle between magnetic north and true geographic north. In some geographic locations, the difference between magnetic and geographic north is great enough to cause the compass to give false readings. If this problem occurs, the compass variance must be set. To set the compass variance: Variance Settings 1. Using the Variance Settings map, find your geographic location and note the zone number. 2. Turn the ignition switch to the On position. If the compass/temperature data is not currently being displayed; momentarily depress and release the Step push button to step through the display options until you have reached the compass/temperature display 3. Depress both the U.S./Metric, and the Step push buttons and hold the buttons down until "VAR" appears in the display. This takes about five seconds. 4. Release both of the push buttons. "VAR" along with the current variance zone will appear in the display. 5. Momentarily depress and release the U.S./Metric push button to step through the zone numbers until the zone number for your geographic location appears in the display. 6. Momentarily depress and release the Step push button to enter the displayed zone number into the compass unit memory 7. Confirm that the correct directions are now indicated by the compass. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Service and Repair > Compass Variation Adjustment Service > Page 6130 Compass: Service and Repair Compass Calibration Service CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the compass. Do not use magnetic tools when servicing the overhead console. The electronic compass unit features a self-calibrating design, which simplifies the calibration procedure. This feature automatically updates the compass calibration while the vehicle is being driven. This allows the compass unit to compensate for small changes in the residual magnetism that the vehicle may acquire during normal use. If the compass readings appear to be erratic or out of calibration, perform the following calibration procedure. Also, new service replacement compass mini-trip computer modules must have their compass calibrated using this procedure. Do not attempt to calibrate the compass near large metal objects such as other vehicles, large buildings, or bridges; or, near overhead or underground power lines. NOTE: Whenever the compass is calibrated manually, the variation number must also be reset. See Compass Variation Adjustment in the Service Procedures. Calibrate the compass manually as follows: 1. Turn the ignition switch to the On position. If the compass/temperature data is not currently being displayed, momentarily depress and release the Step push button to step through the display options until you have reached the compass/temperature display 2. Depress both the U.S./Metric and the Step push buttons. Hold the push buttons down until "CAL" appears in the display This takes about ten seconds, and appears about five seconds after "VAR" is displayed. 3. Release both of the push buttons. 4. Drive the vehicle on a level surface, away from large metal objects and power lines, through three or more complete circles in not less than 48 seconds. The "CAL" message will disappear from the display to indicate that the compass is now calibrated. NOTE: If the "CAL" message remains in the display, either there is excessive magnetism near the compass, or the unit is faulty. Repeat the calibration procedure at least one more time. - If the wrong direction is still indicated in the compass display, the area selected for calibration may be too close to a strong magnetic field. Repeat the calibration procedure in another location. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Compass > Component Information > Service and Repair > Compass Variation Adjustment Service > Page 6131 Compass: Service and Repair Compass Demagnetizing Service A degaussing tool (Special Tool 6029) is used to demagnetize, or degauss, the overhead console forward mounting screw and the roof panel above the overhead console. Equivalent units must be rated as continuous duty for 110/115 volts and 60 Hz. They must also have a field strength of over 350 gauss at 7 millimeters (0.25 inch) beyond the tip of the probe. To demagnetize the roof panel and the overhead console forward mounting screw, proceed as follows: 1. Be certain that the ignition switch is in the Off position, before you begin the demagnetizing procedure. 2. Connect the degaussing tool to an electrical outlet, while keeping the tool at least 61 centimeters (2 feet) away from the compass unit. 3. Slowly approach the head of the overhead console forward mounting screw with the degaussing tool connected. 4.

The sending unit consists of a float, an arm, and a variable resistor (track). The resistor track is used to send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for OBD II emission requirements. For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and arm move down. This increases the sending unit resistance causing the fuel gauge to read empty. After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading. For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the sending unit to the PCM to indicate fuel level. The purpose of this feature is to prevent the OBD II system from recording/setting false misfire and fuel system monitor trouble codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will also be activated if the fuel level in the tank is more than approximately 85 percent of its rated capacity. Fuel Tank/Fuel Pump Module Fuel Pump Module Components (Typical Pump Module Shown) FUEL PUMP MODULE The fuel pump module on all models/all engines is installed in the top of the fuel tank.

The lamp lenses are the only visible components of these lamps. The reading and courtesy lamp lenses are mounted in the overhead console housing between the compass mini-trip computer display and the sunglasses storage bin. Each lamp has its own switch, bulb, and lens; but both lamps share a common lamp housing within the overhead console. The overhead console reading and courtesy lamps operate on battery current that is provided at all times, regardless of the ignition switch position. The ground feed for the lamps is switched through the integral reading and courtesy lamp switches or through the door jamb switches. Each lamp is designed and aimed to provide illumination that will be directed only to that side of the vehicle on which the lamp is located. The reading and courtesy lamp lenses, bulbs and the lamp housing are available for service replacement. The reading and courtesy lamp switches, bulb holders and wiring are only available as part of the overhead console wire harness. If either of the lamp switches or bulb holders is faulty or damaged, the entire overhead console wire harness assembly must be replaced. For service of the reading and courtesy lamp bulbs, refer to Overhead Console Reading Lamp Bulbs in the Replacement. For diagnosis of the reading and courtesy lamps, refer to Lamp Diagnosis in the Diagnosis and Testing of Lamps. OPERATION All reading and courtesy lamps located in the overhead console are activated by the door jamb switches. When all of the doors are closed, these lamps can be individually activated by depressing the corresponding lens. When any door is open, depressing the lamp lenses to activate the lamp switches will not turn the lamps off. See the owner's manual in the vehicle glove box for more information on the use and operation of the overhead console reading and courtesy lamps. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Instrument Cluster / Carrier > Instrument Panel Bulb > Map Lamp > Component Information > Service and Repair > Overhead Console Reading and Courtesy Lamp Housing Replacement Map Lamp: Service and Repair Overhead Console Reading and Courtesy Lamp Housing Replacement REMOVAL 1.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6206 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6207 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6208 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6209 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6210 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6221 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6222 3.

Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6223 Central Timer Module ( CTM ) Low Option: Connector Views Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6224 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6225 Central Timer Module ( CTM ) Low Option: Electrical Diagrams Component Diagrams 8w-45-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6226 8w-45-3 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6227 8w-45-4 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6228 8w-45-5 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6229 8w-45-6 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6230 8w-45-7 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6231 8w-45-8 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6232 8w-45-9 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6233 8w-45-10 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel > Central Timer Module ( CTM ) Low Option <--> [Audible Warning Device Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 6234 8w-45-11 NOTE: To view sheets referred to in these diagrams, see Complete Body and Chassis Diagrams.

The fuel pump module is located inside of fuel tank. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 6254 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 6255 Fuel Gauge Sender: Description and Operation FUEL GAUGE SENDING UNIT The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The sending unit consists of a float, an arm, and a variable resistor (track). The resistor track is used to send electrical signals to the Powertrain Control Module (PCM) for fuel gauge operation and for OBD II emission requirements. For fuel gauge operation: As fuel level increases, the float and arm move up. This decreases the sending unit resistance, causing the fuel gauge to read full. As fuel level decreases, the float and arm move down. This increases the sending unit resistance causing the fuel gauge to read empty. After this fuel level signal is sent to the PCM, the PCM will transmit the data across the CCD bus circuits to the instrument panel. Here it is translated into the appropriate fuel gauge level reading. For OBD II emission monitor requirements: A voltage signal is sent from the resistor track on the sending unit to the PCM to indicate fuel level. The purpose of this feature is to prevent the OBD II system from recording/setting false misfire and fuel system monitor trouble codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will also be activated if the fuel level in the tank is more than approximately 85 percent of its rated capacity. Fuel Tank/Fuel Pump Module Fuel Pump Module Components (Typical Pump Module Shown) FUEL PUMP MODULE The fuel pump module on all models/all engines is installed in the top of the fuel tank. The fuel pump module contains the following components: A combination fuel filter/fuel pressure regulator - Electric fuel pump - Fuel pump reservoir - A separate in-tank fuel filter (at bottom of module) Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 6256 - Fuel gauge sending unit (fuel level sensor) - Fuel supply line connection at filter/regulator - A threaded locknut retain pump module to fuel tank - A gasket between tank flange and module The fuel gauge sending unit (fuel level sensor), and pick-up filter (at bottom of module) may be serviced separately. If the electrical fuel pump requires service, the entire fuel pump module must be replaced. The fuel filter/fuel pressure regulator may be serviced separately. Refer to Fuel Filter/Fuel Pressure Regulator Removal/installation for additional information. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Sensors and Switches - Instrument Panel > Fuel Gauge Sender > Component Information > Specifications > Page 6257 Fuel Gauge Sender: Testing and Inspection The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down, electrical resistance will change. Refer to Instrument Panel and Gauges for Fuel Gauge testing. To test the gauge sending unit only, it must be removed from vehicle.

The instrument cluster circuitry controls the gauge pointer position. The instrument cluster circuitry calculates the proper gauge pointer position based upon vehicle speed messages received from the Powertrain Control Module (PCM) on the Chrysler Collision Detection (CCD) data bus. The PCM uses a speed pulse input received from the Controller Anti-lock Brake (CAB) and internal programming to decide what vehicle speed and distance messages are required. The PCM then sends the proper messages to the instrument cluster circuitry on the CCD data bus. The CAB uses an input from the rear wheel speed sensor and internal programming, which includes a programmable pinion factor to compensate for different axle gear ratios and tire sizes, to determine what speed pulse output is required. The CAB then sends the proper speed pulse to the PCM on a hard-wired circuit. The rear wheel speed sensor is excited by an exciter ring on the differential case within the rear axle housing. Incorrect tire size incorrect axle ratio, an incorrect pinion factor, a faulty or improperly installed rear wheel speed sensor, a faulty rear axle exciter ring, or a faulty CAB can each result in inaccurate speedometer readings. For diagnosis of the speedometer inputs, a DRB scan tool and the proper Diagnostic Procedures are recommended. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Speedometer Head > Component Information > Description and Operation > Page 6271 Speedometer Head: Testing and Inspection If the problem being diagnosed is related to speedometer accuracy, be certain to confirm that the problem is with the speedometer gauge and not with an incorrect pinion factor, axle ratio, or tire size.

The mechanical gear selector indicator gives an indication of the transmission gear that has been selected with the automatic transmission gear selector lever. The indicator housing is mounted to the rear of the instrument cluster housing. The gear selector indicator pointer is easily visible through an opening provided in the front of the instrument cluster mask, and is also lighted by the cluster illumination lamps for visibility at night. This information covers only the removal and installation of the gear selector indicator from the instrument cluster. OPERATION The gear selector indicator has a spring-loaded pointer that is mechanically actuated by a cable connected to the gear selector indicator driver lever of the gear selector lever mechanism on the steering column. When the gear selector lever is moved the indicator driver lever moves, which actuates the spring-loaded pointer through the mechanical actuator cable. An adjuster mounted on the steering column housing provides a mechanical means of calibrating the gear selector indicator mechanism. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Transmission Shift Position Indicator Lamp > Component Information > Specifications > Page 6281 Transmission Shift Position Indicator Lamp: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The switch is also used to send signals to components that must know when the brakes are applied, such as the Powertrain Control Module (PCM), which uses the signal to cancel speed control. The CAB uses the brake switch signal to monitor brake pedal application. When the switch contacts open (brakes applied), the CAB receives the brake applied signal. The CAB then monitors the RWAL system to anticipate the need for an RWAL stop. When the brake light switch is activated, the Powertrain Control Module (PCM) receives an input indicating that the brakes are being applied. After receiving this input, the PCM maintains idle speed to a scheduled rpm through control of the Idle Air Control (IAC) motor. The brake switch input is also used to disable vent and vacuum solenoid output signals to the speed control servo. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Brake Light Switch > Component Information > Description and Operation > With Antilock Brakes > Page 6304 Brake Light Switch: Description and Operation With Standard Brakes The content of this article reflects the changes called out by TSB 26-05-99.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only. Circuit Function Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6358 Circuit Identification Code Chart All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6359 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6360 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from its protective packing until it is time to install the part. 5. Before removing the part from its package, ground the package to a known good ground on the vehicle. Fasteners Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6361 Shock Tower To Spring Minimum Clearance Area CAUTION: At no time when servicing a vehicle, can a sheet metal screw, bolt, or other metal fastener be installed in the strut tower to take the place of an original plastic clip. Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6362 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring. Symbols Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6363 Wiring Diagram Symbols International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used around the world. Take-Outs The abbreviation T/O is used in the component location to indicate a point at which the wiring harness branches out to a component. How to Find System & Component Diagrams When trying to find the diagram for a specific component or system, use the Group Index information or the Alphabetic Index to Wiring Diagrams under Electrical Whenever a reference exists to another sheet or figure, find the corresponding diagram using the Group Index, Diagrams By Sheet Number, or Diagrams By Figure Number.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6373 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6374 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6375 Hazard Warning Flasher: Connector Views 8w-12-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6376 8w-12-3 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6377 8w-12-5 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6378 Combination Flasher - Typical Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Page 6379 Hazard Warning Flasher: Service Precautions WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY . Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Page 6380 Hazard Warning Flasher: Description and Operation DESCRIPTION The combination flasher is a smart relay that functions as both the turn signal system and the hazard warning system flasher. The combination flasher contains active electronic Integrated Circuitry (IC) elements. This flasher is designed to handle the current flow requirements of the factory-installed lighting. If supplemental lighting is added to the turn signal lamp circuits, such as when towing a trailer with lights, the combination flasher will automatically try to compensate to keep the flash rate the same. While the combination flasher has a International Standards Organization (ISO)-type relay terminal configuration or footprint, the internal circuitry is much different. The combination flasher does not use standard ISO-relay inputs or provide ISO-relay type outputs or functions. The combination flasher should never be substituted for an ISO-relay or replaced with an ISO-relay, or else component and vehicle damage may occur. Because of the active electronic elements within the combination flasher, it cannot be tested with conventional automotive electrical test equipment. If the combination flasher is believed to be faulty, test the turn signal system and hazard warning system circuits as described. Then replace the combination flasher with a known good unit to confirm system operation. The combination flasher has five blade-type terminals intended for the following inputs and outputs: fused B(+), fused ignition switch output, ground, turn signal circuit, and hazard warning circuit. Constant battery voltage and ground are supplied to the flasher so that it can perform the hazard warning function, and ignition switched battery voltage is supplied for the turn signal function. The combination flasher is located in the junction block behind the fuse access panel on the left end of the instrument panel. The combination flasher cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. Combination Flasher - Typical OPERATION The IC within the combination flasher contains the logic that controls the flasher operation and the flash rate. Pin 6 of the IC receives a sense voltage from the hazard warning circuit of the multi-function switch. When the hazard warning switch is turned on, the "hazard on sense voltage will become low due to the circuit being grounded through the turn signal bulbs. This low voltage sense signals the IC to energize the flash control Positive-Negative-Positive (PNP) transistor at a pre-calibrated flash rate or frequency Each time the PNP transistor energizes the hazard warning circuit, the pin 6 "hazard on sense" voltage will become high and the IC signals the PNP transistor to de-energize the circuit. This cycling will continue until the hazard warning switch is turned off. Likewise, pin 8 of the IC receives a sense voltage from the turn signal circuits of the multi-function switch. When the left or right turn signal switch is turned on, the "turn signal on sense" voltage will become low due to the circuit being grounded through the turn signal bulbs. This low voltage sense signals the IC to energize the flash control PNP transistor at a pre-calibrated flash rate or frequency. Each time the PNP transistor energizes the turn signal circuit, the pin 8 "turn signal on sense" voltage will become high and the IC signals the PNP transistor to de-energize the circuit. This cycling will continue until the right or left turn signal switch is turned off. A special design feature of the combination flasher allows it to "sense" that a turn signal circuit or bulb is not operating, and provide the driver an indication of the condition by flashing the remaining bulbs in the affected circuit at a higher rate (120 flashes-per-minute or higher;). Conventional flashers either continue flashing at their typical rate (heavy-duty type), or discontinue flashing the affected circuit entirely (standard-duty type). During turn signal operation, the combination flasher IC compares normal battery voltage input on pin 2 with the shunt resistor voltage input on pin 7. If the IC "senses" that the voltage difference between pin 2 and pin 7 is different than the pre-calibrated value of the IC, it will increase the rate at which it signals the PNP transistor to energize the pin 1 output. Thus, the inoperative half (left or right side) of the turn signal circuit will flash faster. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Flasher > Component Information > Diagrams > Page 6381 Hazard Warning Flasher: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The only visible parts of the multi-function switch are the control stalk that extends from the left side of the steering column, and the hazard warning switch push button that protrudes from the top of the steering column. The multi-function switch control stalk has both nomenclature and international control symbols on it, which identify its many functions. The hazard warning switch push button is identified with a double triangle, which is the international control symbol for hazard warning. The remainder of the multi-function switch is concealed beneath the steering column shrouds. The multi-function switch also contains circuitry for the following functions: Headlamp beam selection - Headlamp optical horn - Windshield wipers - Windshield washers. The information contained addresses only the multi-function switch turn signal and hazard warning functions. However, the turn signal and hazard warning switches cannot be repaired. If these switches or any other circuit or component of the multi-function switch unit is faulty or damaged, the entire Multifunction switch unit must be replaced. OPERATION The hazard warning switch is controlled by the hazard warning switch push button. Push the switch button in to unlatch the switch and activate the hazard warning system, and push in on the button again to latch the switch and turn the system off. When the hazard warning switch is latched (hazard warning off), the push button will be in a lowered position on the top of the steering column shroud; and, when the hazard warning switch is unlatched (hazard warning on), the push button will be in a raised position. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Switch > Component Information > Specifications > Page 6388 Hazard Warning Switch: Testing and Inspection The turn signal switch and the hazard warning switch are integral to the multi-function switch.

The horn relay is located in the Power Distribution Center (PDC) in the engine compartment. If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the PDC until further diagnosis is completed. See the fuse and relay layout label affixed to the inside surface of the PDC cover for horn relay identification and location. The horn relay is a International Standards Organization (ISO) micro-relay. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. The ISO micro-relay terminal functions are the same as a conventional ISO relay. However the ISO micro-relay terminal pattern (or footprint) is different, the current capacity is lower, and the physical dimensions are smaller than those of the conventional ISO relay. If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the PDC until further diagnosis is completed. The horn relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one movable) electrical contacts. The movable (common feed) relay contact is held against one of the fixed contacts (normally closed) by spring pressure. When the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Horn > Horn Relay > Component Information > Locations > Page 6432 Horn Relay: Testing and Inspection Horn Relay The horn relay is located in the Power Distribution Center (PDC) behind the battery on the driver side of the engine compartment.

The switch consists of two plastic membranes, one that is flat and one that is slightly convex. These two membranes are secured to each other around the perimeter. Inside the switch, the centers of the facing surfaces of these membranes each has a grid made with an electrically conductive material applied to it. One of the grids is connected to a circuit that provides it with continuity to ground at all times. The grid of the other membrane is connected to the horn relay control circuit. The steering wheel and steering column must be properly grounded in order for the horn switch to function properly. The horn switch is only serviced as a part of the driver side airbag module trim cover. If the horn switch is damaged or faulty, or if the driver side airbag is deployed, the driver side airbag module trim cover and horn switch must be replaced as a unit. OPERATION When the center area of the driver side airbag trim cover is depressed, the electrically conductive grids on the facing surfaces of the horn switch membranes contact each other, closing the switch circuit. The completed horn switch circuit provides a ground for the control coil side of the horn relay, which activates the relay. When the horn switch is released, the resistive tension of the convex membrane separates the two electrically conductive grids and opens the switch circuit. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Horn > Horn Switch > Component Information > Locations > Page 6439 Horn Switch: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The horn relay is located in the Power Distribution Center (PDC) in the engine compartment. If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the PDC until further diagnosis is completed. See the fuse and relay layout label affixed to the inside surface of the PDC cover for horn relay identification and location. The horn relay is a International Standards Organization (ISO) micro-relay. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. The ISO micro-relay terminal functions are the same as a conventional ISO relay. However the ISO micro-relay terminal pattern (or footprint) is different, the current capacity is lower, and the physical dimensions are smaller than those of the conventional ISO relay. If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the PDC until further diagnosis is completed. The horn relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. OPERATION The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one movable) electrical contacts. The movable (common feed) relay contact is held against one of the fixed contacts (normally closed) by spring pressure. When the electromagnetic coil is energized, it draws the movable contact away from the normally closed fixed contact, and holds it against the other (normally open) fixed contact. When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Relays and Modules - Lighting and Horns > Horn Relay > Component Information > Locations > Page 6486 Horn Relay: Testing and Inspection Horn Relay The horn relay is located in the Power Distribution Center (PDC) behind the battery on the driver side of the engine compartment.

The switch is also used to send signals to components that must know when the brakes are applied, such as the Powertrain Control Module (PCM), which uses the signal to cancel speed control. The CAB uses the brake switch signal to monitor brake pedal application. When the switch contacts open (brakes applied), the CAB receives the brake applied signal. The CAB then monitors the RWAL system to anticipate the need for an RWAL stop. When the brake light switch is activated, the Powertrain Control Module (PCM) receives an input indicating that the brakes are being applied. After receiving this input, the PCM maintains idle speed to a scheduled rpm through control of the Idle Air Control (IAC) motor. The brake switch input is also used to disable vent and vacuum solenoid output signals to the speed control servo. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Brake Light Switch > Component Information > Description and Operation > With Antilock Brakes > Page 6504 Brake Light Switch: Description and Operation With Standard Brakes The content of this article reflects the changes called out by TSB 26-05-99.

The switch consists of two plastic membranes, one that is flat and one that is slightly convex. These two membranes are secured to each other around the perimeter. Inside the switch, the centers of the facing surfaces of these membranes each has a grid made with an electrically conductive material applied to it. One of the grids is connected to a circuit that provides it with continuity to ground at all times. The grid of the other membrane is connected to the horn relay control circuit. The steering wheel and steering column must be properly grounded in order for the horn switch to function properly. The horn switch is only serviced as a part of the driver side airbag module trim cover. If the horn switch is damaged or faulty, or if the driver side airbag is deployed, the driver side airbag module trim cover and horn switch must be replaced as a unit. OPERATION When the center area of the driver side airbag trim cover is depressed, the electrically conductive grids on the facing surfaces of the horn switch membranes contact each other, closing the switch circuit. The completed horn switch circuit provides a ground for the control coil side of the horn relay, which activates the relay. When the horn switch is released, the resistive tension of the convex membrane separates the two electrically conductive grids and opens the switch circuit. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Horn Switch > Component Information > Locations > Page 6545 Horn Switch: Testing and Inspection WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

If these switches or any other circuit or component of the multi-function switch unit is faulty or damaged, the entire Multifunction switch unit must be replaced. OPERATION The multi-function switch control stalk that extends from the left side of the steering column just below the steering wheel is moved up or down to activate the turn signal switch. When the control stalk is moved in the upward direction, the right turn signal switch circuitry is activated; and, when the control stalk is moved in the downward direction, the left turn signal switch circuitry is activated. The turn signal switch has a detent position in each direction that provides turn signals with automatic cancellation, and an intermediate momentary position in each direction that provides turn signals only until the multi-function switch control stalk is released. When the turn signal switch is in a detent position, it is turned off by one of two turn signal cancelling cam lobes that are integral to the rotor of the clockspring mechanism. Turning the steering wheel causes the turn signal cancelling cam lobes to contact a cancel actuator in the multi-function switch, and the turn signal switch automatically returns to the off position. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Turn Signal Switch > Component Information > Specifications > Page 6553 Turn Signal Switch: Testing and Inspection The turn signal switch and the hazard warning switch are integral to the multi-function switch.

In order to effectively use Chrysler wiring diagrams to diagnose and repair a Chrysler vehicle, it is important to understand all of their features and characteristics. Diagrams are arranged such that the power (B+) side of the circuit is placed near the top, and the ground (B-) side of the circuit is placed near the bottom. All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition. Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around a component indicates that the component being shown is not complete. Incomplete components have a reference number to indicate where the component is shown complete. It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only.

To identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This chart shows the main circuits only and does not show the secondary codes that may apply to some models. Circuit Information Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6577 Wire Code Identification Wire Color Code Chart Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main circuit, gauge of wire, and color. Connector Information CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A typical example might be the Supplemental Restraint System connectors. Always check parts availability before attempting a repair. IDENTIFICATION In-line connectors are identified by a number, as follows: In-line connectors located on the engine compartment harness are C100 series numbers. - Connectors located on the instrument panel harness are C200 series numbers. - Connectors located on the body harness are C300 series numbers. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6578 - Jumper harness connectors are C400 series numbers. - Grounds and ground connectors are identified with a "G" and follow the same series numbering as the in-line connector. Component Identification Component connectors are identified by the component name instead of a number. Connector Identification Multiple connectors on a component use a C1, C2, etc. identifier. Electrostatic Discharge (ESD) Sensitive Devices Electrostatic Discharge Symbol All Electrostatic Discharge (ESD) sensitive components are solid state and a symbol is used to indicate this. When handling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build-up on the body and inadvertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is. 1. Always touch a known good ground before handling the part. This should be repeated while handling the part, especially after sliding across a seat, sitting down from a standing position, or walking a distance. 2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure. 3. When using a voltmeter, be sure to connect the ground lead first. 4.

Also, NO holes can be drilled into the front strut tower in the area shown in for the installation of any metal fasteners into the strut tower. Because of the minimum clearance in this area , installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is lost or broken during servicing of a vehicle, replace it only with the equivalent part listed in the parts catalog. Fuses CAUTION: When replacing a blown fuse, it is important to replace it with a fuse having the correct amperage rating. The use of a fuse with a rating other than that indicated may result in an electrical overload. If a properly rated fuse continues to blow, it indicates a problem that should be corrected. Notes, Cautions and Warnings Additional important information is presented in three ways: Notes, Cautions, and Warnings. NOTES are used to help describe how switches or components operate to complete a particular circuit. They are also used to indicate different conditions that may appear on the vehicle. For example, an up-to and after condition. CAUTIONS are used to indicate information that could prevent making an error that may damage the vehicle. WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of general warnings that should be followed any time a vehicle is being serviced. WARNING: - ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION. - USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE. - BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE PROCEDURE REQUIRES IT TO BE ON. - SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN NEUTRAL. - OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA. - KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE FAN AND BELTS. - TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER. - DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. - ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Positive Temperature Coefficient Positive Temperature Coefficient (PTC) devices are being used for circuit protection. These PTC's act like a solid state fuse. They are located in the Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6580 junction block, and are used to protect such items as: power door lock motors, power windows, and various engine solenoids. Positive Temperature Coefficient Symbol A special symbol is used to identify these in the wiring diagrams. Section Identification Wiring Diagram Section Identification The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shut Down Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.

It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly check the following items. - Connectors are fully seated - Spread terminals, or terminal push out - Terminals in the wiring assembly are fully seated into the connector/component and locked in position - Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem - Damaged connector/component casing exposing the item to dirt and moisture - Wire insulation that has rubbed through causing a short to ground - Some or all of the wiring strands broken inside of the insulation covering. - Wiring broken inside of the insulation Troubleshooting Tests Before beginning any tests on a vehicle's electrical system, use the wiring diagrams to study the circuit. Also refer to Troubleshooting Wiring Problems section. Testing For Voltage Testing For Voltage 1. Connect the ground lead of a voltmeter to a known good ground. 2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6591 Testing For Continuity Testing For Continuity 1. Remove the fuse for the circuit being checked or disconnect the battery. 2. Connect one lead of the ohmmeter to one side of the circuit being tested. 3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity. Testing For A Short To Ground 1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness every 6 to 8 Inches and watch the voltmeter/test light. 4. If the voltmeter registers voltage or the test light glows, there is a short-to-ground in that general area of the wiring harness. Testing For A Short-to-ground On Fuses Powering Several Loads 1. Refer to the wiring diagrams and disconnect or isolate all items on the fuse circuit. 2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery. 4. Start connecting the items in the fuse circuit, one at a time. When the fuse blows, the circuit with the short-to-ground has been isolated. Testing For Voltage Drop Testing For Voltage Drop 1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery. 2. Connect the other lead of the voltmeter to the other side of the switch or component. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6592 3. Operate the item. 4. The voltmeter will show the difference in voltage between the two points. Troubleshooting Tools TROUBLESHOOTING TOOLS When diagnosing a problem in an electrical circuit, there are several common tools necessary. These tools are listed and explained below. - Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit. WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND. - Voltmeter - This instrument is used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking voltages in these circuits, use a meter with a 10 megohm or greater impedance. - Ohmmeter - This instrument is used to check the resistance between two points of a circuit. Low or no resistance in a circuit can mean good continuity or a shorted circuit. CAUTION: Most of the electrical components used in today's vehicle are solid state. When checking resistance in these circuits, use a meter with a 10 megohm or greater impedance. In addition, be sure the power is disconnected from the circuit. Circuits that are powered-up by the vehicle electrical system can cause damage to the equipment and provide false readings. Probing Tool - Probing Tools - These tools are used for probing terminals in connectors. Select the proper size tool from Special Tool Package 6807 and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe. Troubleshooting Wiring Problems When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. Always check for non-factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. 1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue. 4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step check for proper operation of all items on the repaired circuit. Refer to the wiring diagrams. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6593 Turn Signal Flasher: Connector Views 8w-12-2 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6594 8w-12-3 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6595 8w-12-5 Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Diagram Information and Instructions > Page 6596 Combination Flasher - Typical Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Page 6597 Turn Signal Flasher: Service Precautions WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The combination flasher contains active electronic Integrated Circuitry (IC) elements. This flasher is designed to handle the current flow requirements of the factory-installed lighting. If supplemental lighting is added to the turn signal lamp circuits, such as when towing a trailer with lights, the combination flasher will automatically try to compensate to keep the flash rate the same. While the combination flasher has a International Standards Organization (ISO)-type relay terminal configuration or footprint, the internal circuitry is much different. The combination flasher does not use standard ISO-relay inputs or provide ISO-relay type outputs or functions. The combination flasher should never be substituted for an ISO-relay or replaced with an ISO-relay, or else component and vehicle damage may occur. Because of the active electronic elements within the combination flasher, it cannot be tested with conventional automotive electrical test equipment. If the combination flasher is believed to be faulty, test the turn signal system and hazard warning system circuits as described. Then replace the combination flasher with a known good unit to confirm system operation. The combination flasher has five blade-type terminals intended for the following inputs and outputs: fused B(+), fused ignition switch output, ground, turn signal circuit, and hazard warning circuit. Constant battery voltage and ground are supplied to the flasher so that it can perform the hazard warning function, and ignition switched battery voltage is supplied for the turn signal function. The combination flasher is located in the junction block behind the fuse access panel on the left end of the instrument panel. The combination flasher cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. Combination Flasher - Typical OPERATION The IC within the combination flasher contains the logic that controls the flasher operation and the flash rate. Pin 6 of the IC receives a sense voltage from the hazard warning circuit of the multi-function switch. When the hazard warning switch is turned on, the "hazard on sense voltage will become low due to the circuit being grounded through the turn signal bulbs. This low voltage sense signals the IC to energize the flash control Positive-Negative-Positive (PNP) transistor at a pre-calibrated flash rate or frequency Each time the PNP transistor energizes the hazard warning circuit, the pin 6 "hazard on sense" voltage will become high and the IC signals the PNP transistor to de-energize the circuit. This cycling will continue until the hazard warning switch is turned off. Likewise, pin 8 of the IC receives a sense voltage from the turn signal circuits of the multi-function switch. When the left or right turn signal switch is turned on, the "turn signal on sense" voltage will become low due to the circuit being grounded through the turn signal bulbs. This low voltage sense signals the IC to energize the flash control PNP transistor at a pre-calibrated flash rate or frequency. Each time the PNP transistor energizes the turn signal circuit, the pin 8 "turn signal on sense" voltage will become high and the IC signals the PNP transistor to de-energize the circuit. This cycling will continue until the right or left turn signal switch is turned off. A special design feature of the combination flasher allows it to "sense" that a turn signal circuit or bulb is not operating, and provide the driver an indication of the condition by flashing the remaining bulbs in the affected circuit at a higher rate (120 flashes-per-minute or higher;). Conventional flashers either continue flashing at their typical rate (heavy-duty type), or discontinue flashing the affected circuit entirely (standard-duty type). During turn signal operation, the combination flasher IC compares normal battery voltage input on pin 2 with the shunt resistor voltage input on pin 7. If the IC "senses" that the voltage difference between pin 2 and pin 7 is different than the pre-calibrated value of the IC, it will increase the rate at which it signals the PNP transistor to energize the pin 1 output. Thus, the inoperative half (left or right side) of the turn signal circuit will flash faster. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Flasher > Component Information > Diagrams > Page 6599 Turn Signal Flasher: Service and Repair WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.

The only visible parts of the multi-function switch are the control stalk that extends from the left side of the steering column, and the hazard warning switch push button that protrudes from the top of the steering column. The multi-function switch control stalk has both nomenclature and international control symbols on it, which identify its many functions. The hazard warning switch push button is identified with a double triangle, which is the international control symbol for hazard warning. The remainder of the multi-function switch is concealed beneath the steering column shrouds. The multi-function switch also contains circuitry for the following functions: Headlamp beam selection - Headlamp optical horn - Windshield wipers - Windshield washers. The information contained addresses only the multi-function switch turn signal and hazard warning functions. However, the turn signal and hazard warning switches cannot be repaired. If these switches or any other circuit or component of the multi-function switch unit is faulty or damaged, the entire Multifunction switch unit must be replaced. OPERATION The multi-function switch control stalk that extends from the left side of the steering column just below the steering wheel is moved up or down to activate the turn signal switch. When the control stalk is moved in the upward direction, the right turn signal switch circuitry is activated; and, when the control stalk is moved in the downward direction, the left turn signal switch circuitry is activated. The turn signal switch has a detent position in each direction that provides turn signals with automatic cancellation, and an intermediate momentary position in each direction that provides turn signals only until the multi-function switch control stalk is released. When the turn signal switch is in a detent position, it is turned off by one of two turn signal cancelling cam lobes that are integral to the rotor of the clockspring mechanism. Turning the steering wheel causes the turn signal cancelling cam lobes to contact a cancel actuator in the multi-function switch, and the turn signal switch automatically returns to the off position. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Switch > Component Information > Specifications > Page 6620 Turn Signal Switch: Testing and Inspection The turn signal switch and the hazard warning switch are integral to the multi-function switch.

These wiper blades include an anti-lift feature. The wiper blades and squeegees must be oriented correctly when installed on the wiper arms for the anti-lift feature to be effective. See Wiper Blade Replacement for more information. Caution should be exercised to protect the rubber squeegees from any petroleum-based cleaners or contaminants, which will rapidly deteriorate the rubber. If the squeegees are damaged, worn, or contaminated, the entire wiper blade assembly must be replaced. Wiper squeegees exposed to the elements for a long time tend to lose their wiping effectiveness. Periodic cleaning of the squeegees is suggested to remove deposits of salt and road film. The wiper blades, arms, and windshield should be cleaned with a sponge or cloth and windshield washer fluid, a mild detergent, or a non-abrasive cleaner. If the squeegees continue to streak or smear, the wiper blades should be replaced. The blades are mounted to spring-loaded wiper arms. The spring tension of the wiper arms controls the pressure applied to the blades on the glass. The windshield wiper arms are secured by a nut to each of the two wiper pivots on the cowl plenum cover/ grille panel at the base of the windshield. The wiper arms and blades cannot be adjusted or repaired. If faulty or damaged, they must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Wiper and Washer Systems > Wiper Arm > Component Information > Specifications > Page 6734 Wiper Arm: Service and Repair REMOVAL AND INSTALLATION CAUTION: The use of a screwdriver or other prying tool to remove a wiper arm may distort it.

Because of the environmental conditions vehicles can be operated in, a film can build up on both the windshield and the windshield wiper elements that will cause poor cleaning/streaking of the windshield, and in some instances, a chattering condition as the wipers blades travel across the windshield. Replacement of the wiper blades/elements is normally NOT required to correct streaking issues. A simple NORMAL MAINTENANCE cleaning of the wiper blades/elements and windshield is all that is required. If the wipe pattern appears to be streaky or if there is chatter and no damage to the wiper blades/elements is obvious, the following steps should be performed: 1. Use a soft cloth or sponge & squeegee and MOPAR Windshield Washer Solvent (p/n 04318067AB, 16 Oz. bottle or p/n 04318068AB, 32 Oz. bottle), MOPAR Glass Cleaner (p/n 04897623AB, 16 Oz. bottle) or a solution of 50/50 alcohol and water, to wash the windshield. 2. Raise the wiper blades off the glass and clean the wiper blade elements (rubber insert) with MOPAR Windshield Washer Solvent or a solution of 50/50 alcohol and water and a soft cloth, paper towel or sponge. 3. Return the wiper blades to their normal operating position and function the washer system. If the wiper blades/elements are not streaking the windshield or chattering, replacing the blade assembly(ies) is not necessary.

Because of the environmental conditions vehicles can be operated in, a film can build up on both the windshield and the windshield wiper elements that will cause poor cleaning/streaking of the windshield, and in some instances, a chattering condition as the wipers blades travel across the windshield. Replacement of the wiper blades/elements is normally NOT required to correct streaking issues. A simple NORMAL MAINTENANCE cleaning of the wiper blades/elements and windshield is all that is required. If the wipe pattern appears to be streaky or if there is chatter and no damage to the wiper blades/elements is obvious, the following steps should be performed: 1. Use a soft cloth or sponge & squeegee and MOPAR Windshield Washer Solvent (p/n 04318067AB, 16 Oz. bottle or p/n 04318068AB, 32 Oz. bottle), MOPAR Glass Cleaner (p/n 04897623AB, 16 Oz. bottle) or a solution of 50/50 alcohol and water, to wash the windshield. 2. Raise the wiper blades off the glass and clean the wiper blade elements (rubber insert) with MOPAR Windshield Washer Solvent or a solution of 50/50 alcohol and water and a soft cloth, paper towel or sponge. 3. Return the wiper blades to their normal operating position and function the washer system. If the wiper blades/elements are not streaking the windshield or chattering, replacing the blade assembly(ies) is not necessary. If the wipe pattern is still objectionable, repeat step 2 several times. If the wipe pattern is still objectionable, replace the wiper blades/elements.

The spring tension of the wiper arms controls the pressure applied to the blades on the glass. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Wiper and Washer Systems > Wiper Blade > Component Information > Technical Service Bulletins > Page 6750 Wiper Blade: Description and Operation SYSTEM OPERATION All Dakota truck models have two 50.8-centimeter (20-inch) windshield wiper blades with non-replaceable rubber elements (squeegees). These wiper blades include an anti-lift feature. The wiper blades and squeegees must be oriented correctly when installed on the wiper arms for the anti-lift feature to be effective. See Wiper Blade Replacement for more information. Caution should be exercised to protect the rubber squeegees from any petroleum-based cleaners or contaminants, which will rapidly deteriorate the rubber. If the squeegees are damaged, worn, or contaminated, the entire wiper blade assembly must be replaced. Wiper squeegees exposed to the elements for a long time tend to lose their wiping effectiveness. Periodic cleaning of the squeegees is suggested to remove deposits of salt and road film. The wiper blades, arms, and windshield should be cleaned with a sponge or cloth and windshield washer fluid, a mild detergent, or a non-abrasive cleaner. If the squeegees continue to streak or smear, the wiper blades should be replaced. The blades are mounted to spring-loaded wiper arms. The spring tension of the wiper arms controls the pressure applied to the blades on the glass. The windshield wiper arms are secured by a nut to each of the two wiper pivots on the cowl plenum cover/ grille panel at the base of the windshield. The wiper arms and blades cannot be adjusted or repaired. If faulty or damaged, they must be replaced. Dodge Dakota R Workshop Manual (R-T 2WD V8-5.9L VIN Z LDC (1999)) Dodge Workshop Manuals > Wiper and Washer Systems > Wiper Blade > Component Information > Technical Service Bulletins > Page 6751 Wiper Blade: Service and Repair REMOVAL AND INSTALLATION NOTE: The notched retainer end of the wiper element should always be oriented towards the end of the wiper blade that is nearest to the wiper pivot. 1.
