MTX transmission durability (Sales Code DEC only).
• Improvement to Intake Air Sensor (IAS) accuracy calibration (Sales Code DEC only).**
• Changes to Enhanced Automated Oil Change Indicator (EAOCI) calibration to more accurately
determine maintenance interval based on engine loads and driving habits.
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 DTCs,
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 available 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.
