Additional Symptoms:
•
•
•
•
Technicians may find that the original vehicle Frequency Operated Button Integrated
Key (FOBIK) does not function properly following replacement of the Wireless
Ignition Node (WIN/WCM). The Secret Key information stored in the PCM may be
corrupt. This update will restore the PCM’s ability to store/transfer valid Secret Key
information (LC vehicles).
Accuracy improvements for the Automatic Oil Change Indicator (AOCI) system.
Engine buck or delay feeling during low speed driving.
Less than desired engine performance during Multiple Displacement System (MDS)
mode transitions.
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: 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
application’s “HELP” tab.
2. Perform the “PCM Replaced” function located in wiTECH under the WCM/WIN module
view under the Miscellaneous Functions tab. This will transfer the current/valid Secret
Key information from the WIN/WCM to the PCM. (applies only to LC vehicles).
3. 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.
POLICY:
Reimbursable within the provisions of the warranty.
