Interior Lighting

Interior Lighting

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:

- Courtesy lamps
- Demand lamps

Both subsystems use the same power supply circuit through the Central Junction Box (CJB) fuse 18 (15A).


Courtesy Lamps

The courtesy lamps are controlled by the LCM. The courtesy 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).


Demand Lamps

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.


Dark Car Feature

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

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