Action Taken When the DTC Sets Conditions for Clearing the MIL/DTC Diagnostic Aids Test Description The numbers below refer to the step numbers on the diagnostic table. 2. This step verifies that the PCM is receiving a signal from the vehicle speed sensor. 3. This step verifies that there are no opens in the circuitry from the vehicle speed sensor to the PCM connector. 7. This step performs a resistance test on the VSS circuits from the PCM connector. • The transmission defaults to 3rd gear. • The PCM inhibits TCC operation. • The PCM illuminates the Malfunction Indicator Lamp (MIL). • The PCM turns OFF the MIL after three consecutive ignition cycles without a failure reported. • A scan tool can clear the DTC from the PCM history. The PCM clears the DTC from the PCM history if the vehicle completes 40 warm-up cycles without a failure reported. • The PCM cancels the DTC default actions when the fault no longer exists and the ignition is OFF long enough in order to power down the PCM. • Check for PRNDL DTC P0705. DTC P0705 affects transmission operation. This may set DTC P0502 falsely. • Check for Electromagnetic Interference (EMI) in circuits 400 and 401. EMI may be induced if the harness is routed along the spark plug wires. • Inspect the wiring for poor electrical connections at the PCM. Inspect the wiring at the TCC brake switch. Look for the following conditions: – A bent terminal – A backed out terminal – A damaged terminal – Poor terminal tension – A chafed wire – A broken wire inside the insulation • When diagnosing for an intermittent short or open condition, massage the wiring harness while watching the test equipment for a change. • Ensure that the VSS is securely tightened to the case extension.

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

Procedures 1. Disconnect the alternator and the Powertrain Control Module (PCM). Check the Violet (VT) (GENerator MONitor or GENMON) wire from the alternator to pin 20 of the PCM connector and the Red/Pink (RD/PK) (GENerator COMmand or GENCOM) wire from the alternator to pin 45 of the PCM for high resistance, an open, or a short to ground. Repair the wiring as needed. 2. If the wiring checks OK, reconnect the PCM and alternator. Start the engine and monitor the VT wire for a roughly 0-10v square wave signal. The signal will be around 40-50% normally with no loads on the system and minimal charging system output. As the load increases, the duty cycle should increase (NOTE: the duty cycle is a positive duty cycle so as the duty cycle increases, the voltage high time increases). 3. If there is no signal on the wire, disconnect the alternator and with key on check the VT wire for roughly 9-10v from the PCM. If OK, jump the Orange/Light Blue (OG/LB) wire to battery voltage and recheck operation with everything connected. This wire should be battery voltage at all time. If the OG/LB wire has battery voltage, the VT wire shows voltage from the PCM but there is no signal on it with the alternator charging, suspect a faulty, defective or incorrect alternator
