Interior Lighting
INTERIOR LIGHTINGThe interior lighting system consists of the following components:
- Smart junction box (SJB)
- Dimmer control switch
- Interior/map lamps
- Cargo lamp
- Vanity mirror lamps
- Door ajar switches (integral to door latch)
- Liftgate/liftgate glass ajar switches
The interior lighting system consists of 2 subsystems:
- Interior lamps
- Demand lamps
The courtesy lamps are controlled by the SJB. The courtesy lamp subsystem consists of the ajar switches, the interior dome lamps, and the overhead console lamps (if equipped). The SJB supplies voltage to the courtesy lamps when the SJB receives the required input.
The demand lamps subsystem consists of the front map lamps, cargo lamp, and the left and right vanity mirror lamps.
The SJB supplies power to the interior lighting system. The SJB sets DTCs if certain circuit failures exist with the interior lighting system.
