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 a customer’s VIN is listed in VIP or your RRT VIN list, perform the repair. For all other
customers that describe the symptom/condition, or if the technician finds any of the DTCs
listed above 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
“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.
NOTE: If the PCM already has the latest software, use inspection LOP 18-19-06-FA to
close the active RRT.
2. Clear any DTCs that may have been set in any module due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allows 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.
POLICY:
Reimbursable within the provisions of the warranty.
