An engine stall while driving can cause a vehicle crash without prior warning.
Repair
Inspect the software level of the Powertrain Control Module (PCM) and if necessary, reprogram the PCM. Inspect the software level of the Transmission Control Module (TCM) and if necessary, reprogram the TCM.
Parts Information
No parts are required to perform this service procedure.
Parts Return
No parts return required for this campaign.
Special Tools
The following special tools are required to perform this repair:
|
wiTECH micro pod II |
|
Laptop Computer |
|
wiTECH Software |
Service Procedure
NOTE: The wiTECH scan tool must be used to perform this recall. The wiTECH software is required to be at the latest release level before performing this procedure. If the reprogramming flash for the PCM or TCM is aborted or interrupted, repeat the procedure.
CAUTION: For 2.4L engine both the PCM and TCM software must be updated during this procedure. Failure to do so may result in undesirable transmission shift quality. First the PCM must be reprogrammed; second the TCM must be programmed.
- 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 volt meter 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.
- Connect the wiTECH micro pod II to the vehicle data link connector.
- Place the ignition in the “RUN” position.
