These faults could be related to the door ajar switch sticking. The other option you have, is to have the vehicle's computer read by ford's diagnostic tester !
The battery saver is activated when the instrument cluster module is not receiving voltage input from the ignition switch (OFF position). The instrument cluster module will then provide ground to the battery saver relay coil, activating the relay, for a period of 10 minutes with the interior lamp (headlamp) switch in the off position, or a maximum period of 30 minutes with the interior lamp (headlamp) switch in the on position or a door is ajar, provided that the instrument cluster module does not receive any other input signals within the time-out period. The activated battery saver relay switches voltage to the demand lamp circuit. After time-out, the instrument cluster module disconnects ground from the battery saver relay coil, disabling the demand lamp circuit.
Inspection and Verification
Verify the customer concern by operating the system.
Visually inspect the following for obvious signs of electrical damage:
VISUAL INSPECTION CHART
Power distribution/junction box (PD/JB) fuse 2 (30A)
Vehicle security module
Instrument cluster module
If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
check that the program card is correctly installed.
Check the connections to the vehicle.
Check the ignition switch position.
If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
Carry out the DATA LINK DIAGNOSTICS test. If the diagnostic tool responds with:
CKT 914, CKT 915 or CKT 693 = ALL ECUS NO RESP/NOT EQUIP, refer to MODULE COMMUNICATIONS NETWORK.
SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out self-test diagnostics.
If the DTCs retrieved are related to the concern, go to Instrument Cluster Diagnostic Trouble Code Index.
If no DTCs related to the concern are retrieved, proceed to the SYMPTOM CHART.
