NOTE: Some vehicles may have been shipped from the plant with summer blend
fuel depending on the build date. Use of this fuel in cold climate regions may
result in false misfire detection. Ensure vehicle fuel tank has been filled with
local winter blend fuel.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all engine systems are functioning as designed. If DTC's other then
the ones listed above are present, record them on the repair order and repair as necessary
before proceeding further with this bulletin.
If a customer describes the symptom/condition or if the technician finds the listed DTC’s,
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. Follow the detailed service procedures
available in DealerCONNECT/TechCONNECT, Refer To Group 8 - Electrical >
Electronic Control Modules - Service Information > Module - Powertrain Control >
Standard Procedures > PCM/ECM Programming.
2. After PCM reprogramming, the following must be performed: clear any DTC's that
may have been set in other modules due to reprogramming. The wiTECH application
will automatically present all DTCs after the flash and allow the tech to clear them.
POLICY:
Reimbursable within the provisions of the warranty.
