Interior Lighting
The interior lighting system consists of the following:
- Lighting control module (LCM)
- Driver door module (DDM)
- Trunk pull-down module
- Instrument panel dimmer switch
- Dome/map combination lamps
- Interior/reading lamps
- Door lamps
- Footwell lamps
- Luggage compartment lamps
- Glove compartment lamp
- Vanity mirror lamps
- Door ajar switches
The interior lighting system consists of 2 subsystems:
- Courtesy lamps
- Demand lamps
The courtesy lamps are controlled by the LCM. The courtesy lamp subsystem consists of the footwell lamps, door lamps, dome/map lamps and the rear reading lamps.
The demand lamps are controlled by the LCM. The demand lamps subsystem consists of the glove compartment lamp, luggage compartment lamps, front map lamps, rear reading lamps, and the left and right vanity mirror lamps. Except for the luggage compartment 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).
