INTERIOR LIGHTING

NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

The interior lighting system consists of the following components:
- Smart junction box (SJB)
- Dimmer control switch
- Interior/map lamps
- Cargo lamp
- Glove compartment lamp
- Vanity mirror lamps
- Door ajar switches
- Puddle lamps

The interior lighting system consists of 2 subsystems:
- Courtesy lamps
- Demand lamps

The courtesy lamps are controlled by the SJB. The courtesy lamp subsystem consists of the interior dome lamps, the puddle 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 are controlled by the SJB. The demand lamps subsystem consists of the glove compartment lamp, all map/reading lamps, and the left and right vanity mirror lamps.

The SJB supplies power to the interior lighting system. The SJB will set DTCs if certain circuit failures exist with the interior lighting system.
