Demand Lamps

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The demand lamps subsystem consists of the map/reading lamps, the vanity mirror lamps located in the visors and the engine compartment lamp. The BCM energizes the battery saver relay to supply voltage to the demand lamps when the battery saver feature is not active.
