1. Connect a battery charger to the 12-volt battery. 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 appropriate Ford diagnostic scan tool. 3. Check the availability of software updates on the following modules and update as required: (1). Secondary on-board diagnostic control module (SOBDM) (2). Battery energy control module (BECM) (3). Secondary on-board diagnostic control module B (SOBDMB) (4). Secondary on-board diagnostic control module C (SOBDMC) (5). Anti-lock brake system (ABS) module NOTE: Only one module may be updated at a time. |
