Service Procedure
A. Reprogramming PCM Procedure
NOTE: Before reprogramming the PCM, verify the Malfunction Indicator
Lamp (MIL) is not illuminated, if illuminated check for O2 sensor fault codes
if any present replace O2 sensors before reprogramming the PCM. Reference
section B. O2 Sensor Replacement Procedure.
NOTE: The wiTECH scan tool must be used to perform this customer
satisfaction notification. The wiTECH software is required to be at the latest
release level before performing this procedure. If the reprogramming flash for
the PCM is aborted or interrupted, repeat the procedure. The PCM software
must be at the latest software calibration level after completing this customer
satisfaction notification.
1. Open the hood. Install a battery charger and verify that the charging rate
provides 13.0 to 13.5 volts. Do not allow the charger to time out during the
flash process. Set the battery charger timer (if so equipped) to continuous
charge.
NOTE: Use an accurate stand-alone voltmeter. The battery charger
voltmeter may not be sufficiently accurate. Voltages outside of the
specified range will cause an unsuccessful flash. If voltage reading is too
high, apply an electrical load by activating the park or headlamps and/or
HVAC blower motor to lower the voltage.
2. Connect the wiTECH micro pod II to the vehicle data link connector.
3. Place the ignition in the “RUN” position.
