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: 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. Reprogram the TCM with the latest software. Detailed instructions for flashing control modules using the wiTECH Diagnostic Application are available by selecting the application’s “HELP” tab. 1. 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. NOTE: Do not clear the shift adaptives in the TCM’s memory. This action may cause the transmission to not shift smoothly until the adaptives are re-learned. -3- 21-019-16 POLICY: Reimbursable within the provisions of the warranty.
