Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Interior Lighting
The interior lighting system consists of the following components:
- Lighting control module (LCM)
- Driver door module (DDM)
- Headlamp switch
- Dome/map combination
- 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 1 (15A).
