download
Fuel Pump Relay 1. Remove fuel pump relay from power distribution center at driver’s side front corner of engine compartment, near the battery. Note terminal identification on fuel pump relay. See Fig. 6 . 2. To check fuel pump relay resistance, use ohmmeter and check resistance between terminals No. 85 and 86 on fuel pump relay. Replace fuel pump relay if resistance is not 70-80 ohms. 3. To check fuel pump relay operation, connect ohmmeter between terminals No. 30 and 87A on fuel pump relay. See Fig. 6 . Ohmmeter should indicate continuity between terminals No. 30 and 87A on fuel pump relay. 4. Connect ohmmeter between terminals No. 30 and 87 on fuel pump relay. See Fig. 6 . Ohmmeter should indicate no continuity between terminals No. 30 and 87 on fuel pump relay. 5. Connect 16-gauge jumper wire between negative battery terminal and terminal No. 85 on fuel pump relay. Connect 16-gauge jumper wire between positive battery terminal and terminal No. 86 on fuel pump relay. 6. Fuel pump relay should now be energized. No continuity should now exist between terminals No. 30 and 87A on fuel pump relay. Continuity should now exist between terminals No. 30 and 87 on fuel pump relay. Disconnect jumper wires. Replace fuel pump relay if defective. 7. If fuel pump relay or wiring circuit failure exists, a Diagnostic Trouble Code (DTC) will be stored in Powertrain Control Module (PCM). See appropriate G – TESTS W/CODES article. Fig. 6: Identifying ASD Relay & Fuel Pump Relay Terminals Courtesy of CHRYSLER CORP.

POWERTRAIN CONTROL MODULE (PCM) Removal & Installation 1. The PCM is located between driver’s side front fender and power distribution center, near battery. See Fig. 1 . Disconnect negative battery cable and then positive battery cable from battery. 2. Remove bolts on side of power distribution center that secure power distribution center to mounting bracket. Remove heat shield from outside of battery. Remove battery. 3. Rotate power distribution center toward the engine to disengage power distribution center from rear mounting bracket. Pull power distribution center toward rear of vehicle to disengage power distribution center from front mounting bracket. 4. Allow power distribution center to lay aside for access to PCM. Remove electrical connectors from PCM. Electrical connectors may be removed by squeezing tabs on electrical connector together and pulling electrical connector from PCM. Remove bolts and PCM. To install, reverse removal procedure. Vehicles equipped with engine or transmission computers may require a relearn procedure after the vehicle battery is disconnected. Vehicle computers memorize and store vehicle operation patterns for optimum driveability and performance. When the vehicle battery is disconnected, this memory is lost. Default data is used until new data from each key start is stored. As the computer restores its memory from each new key start, driveability is restored. Driveability problems may occur during the relearn stage. Depending on the vehicle and how it is equipped, the following driveability problems may exist: z Rough or unstable idle. z Hesitation or stumble. z Rich or lean running. z Poor fuel mileage. z Harsh or poor transmission shift quality. To accelerate relearn process after battery removal and installation, vehicle should be road tested in the following manner: z Vehicle at normal operating temperature (cooling fan cycles). z Accelerate at normal throttle position (20-50%). z Cruise at light to medium throttle. z Decelerate to a stop, downshifting and using brakes normally. Manufacturers identify specific relearn procedures. See RELEARN PROCEDURES. Always complete the procedure before returning the vehicle to the owner. RELEARN PROCEDURES Theft Alarm Relearn Procedure 1. Theft alarm relearn is necessary whenever battery is disconnected or dead battery is boosted. If battery is connected or boosted without conducting relearn procedure, alarm system will enter power-up mode and vehicle will not start. 2. Before reconnecting battery or connecting booster, insert door key into driver side door lock
