DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all related systems are functioning as designed. If DTCs or
symptom conditions, other than the ones listed above are present, record the issues on the
repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes the symptom/condition listed above or if the technician finds the
DTC, perform the Repair Procedure.
REPAIR PROCEDURE:
NOTE: The Transmission Control Module (TCM) must be updated to the latest
available software at the conclusion of this repair procedure. Refer to all
applicable published service bulletins for detailed repair procedures and
labor times regarding updating the TCM software.
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2
volts. Do not allow the charging voltage to climb above 13.5 volts during the
flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
1. Reprogram the PCM with the latest software. Detailed instructions for flashing control
modules using the wiTECH Diagnostic Application are available by selecting the
application’s “HELP” tab.
2. Clear all DTCs that may have been set in any module due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow them
to be cleared.
3. Verify the TCM is programmed with the latest available software. Refer to all
applicable published service bulletins for detailed repair procedures and labor times
regarding updating the TCM software.
