DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all vehicle 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: 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 TCM with the latest available software. Detailed instructions for
flashing control modules using the wiTECH Diagnostic Application are available by
selecting the “HELP” tab on the upper portion of the wiTECH window, then “HELP
CONTENTS.” This will open the Welcome to wiTECH Help screen where help topics
can be selected.
2. Clear any DTCs that may have been set in any modules due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow the
tech to clear them.
NOTE: Do not clear the adaptation memory cells in the TCM’s memory. Clearing the
memory cells may cause the transmission to not shift smoothly until they
can be fully relearned.
