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.

Reprogram the PCM with the latest available software. Detailed instructions for flashing control modules using the wiTECH Diagnostic Application are available by selecting the application's "HELP" tab.
NOTE: If the phonic wheel replacement procedure is not done correctly, DTC P1300 - Flywheel Self Learning, will stay active.
Using wiTECH 2, perform a Body Control Module (BCM) "Proxi Alignment." The procedure is located in BCM under misc. functions.
Using wiTECH 2, go into the ECM Misc. Functions tab and perform the "Phonic Wheel Replacement" routine.
Fully press the accelerator pedal (bring RPM up to limitation), then release up to idle three times. If the procedure was performed properly the MIL lamp will stop blinking.
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.
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.
