Service Procedure
1. Replace the HVBJB. Refer to Workshop Manual (WSM), Section 414-03A, Removal and installation.
2. Reprogram the BECM to latest software available. The BECM is part of the powertrain coordinated flash.
(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.
3. Reprogram the PCM using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool.
4. Check the availability of software updates on the following modules and update as required:
SOBDM
BECM
SOBDMB
SOBDMC
ABS module
NOTE: Only one module may be updated at a time.
5. Clear any stored DTCs related to this concern.
6. If DTCs P0ADA, P0ADE, P0AA1, and/or P0AA4 remain present, download and run the BECM - Reset Diagnostic
Trouble Code (DTC) Occurrence Counter application in FDRS.
