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 than
the one listed above are present record them on the repair order and repair as necessary
before proceeding further with this bulletin.
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. Help using the wiTECH Diagnostic
Application for flashing control modules is available through the wiTECH Diagnostic
Application. For instructions select the “HELP” tab on upper portion of the wiTECH
window, then “HELP CONTENTS”. This will open the Welcome to wiTECH Help
screen where help topics can be selected.
2. After PCM reprogramming, the following must be performed:
a. 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.
b. Perform a Reset of SCR Long Term Adaptation Factor. From PCM View select
Misc. Functions > double click “Reset of SCR Long Term Adaptation Factor” > Click
Continue.
