Service Procedure
1. Connect a battery charger to the 12-volt battery. If the 12-volt battery is discharged, charge the battery. Refer to
WSM, Section 414-01, Diagnosis and Testing.
NOTE: To prevent the battery saver mode from activating on the vehicle, make sure the negative cable of the
charger is installed on a chassis or engine ground and not the 12-volt battery negative terminal. Do not have
the vehicle plugged into the high voltage battery charger during programming. This can cause incorrect
module programming. Make sure only the 12-volt battery charger is installed.
2. Reprogram the PCM using the latest software level of the FDRS scan tool. Follow all on-screen instructions
carefully to complete all required coordinated module software update(s), including:
SOBDM
BECM
