Normal Operation

WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The delayed accessory relay coil receives power from the battery saver relay through circuit 54 (LG/YE) whenever the ignition is in the RUN or ACCESSORY position. The battery saver relay is integral to the instrument cluster (IC). The IC simultaneously activates the battery saver and the delayed accessory relays by grounding the relay coils when the ignition switch is in the RUN or ACCESSORY position. The IC grounds the delayed accessory relay through circuit 1332 (LB). The delayed accessory relay will remain active for 10 minutes after the ignition is turned OFF, or until a door is opened. When the delayed accessory relay is active, power is sent to the audio system, roof opening panel, power sliding window and power window system.
