On the battery which is subject to a charging, remove a "weight" wire from the negative plug. But before you remove the plug from the battery, write down codes of the receiver and its adjusted frequencies. The system of electronic control after removal of the plug "will forget" the most part of the information. It is switched to short time in emergency operation and restored after run of 16 km. If it does not occur, go to the service center Ford and reprogram the control unit.
