Interior Lighting

WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

The interior lighting system consists of the following components:

Lighting control module (LCM)
Driver door module (DDM)
Instrument panel dimmer switch
Dome/map combination
Red/White map lamp (Police if equipped)
Interior/reading lamps
Footwell lamps
Luggage compartment lamp
Glove compartment lamp
Vanity mirrors
Door ajar switches

The interior lighting system consists of 2 subsystems:

Interior lamps
Demand lamps

The interior lamps are controlled by the LCM. The interior lamp subsystem consists of the footwell lamps, map lamps and the overhead console lamps. The LCM controls the interior lamps by providing power through circuit 53 (BK/LB).

The demand lamps subsystem consists of the glove compartment lamp, luggage compartment lamp, front map lamps, rear reading lamps, and the left and right vanity mirror lamps. Each of these lamps are switched individually and use a separate ground circuit.

Both subsystems use the same power supply circuit through the central junction box (CJB) fuse 18 (15A).

On police vehicles only, the dark car feature is an option that will override the illuminated entry function. If the feature is activated, the courtesy lamps will not illuminate during entry or exit of the vehicle. However, the interior lamps will still illuminate when switched on from the instrument panel dimmer switch.

The dark car feature is enabled/disabled through programmable parameters in the LCM.
