Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in

before proceeding further with this bulletin.
If the customer describes the symptom/condition or if the technician finds the DTCs,
perform the Repair Procedure.

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
“HELP” tab on the upper portion of the wiTECH window, then “HELP CONTENTS.”
This will open the Welcome to wiTECH Help screen where help topics can be
selected.
