Interior Lighting

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:
- SJB
- Instrument panel dimmer switch
- Interior/map lamps
- Door ajar switches
- Luggage compartment lamp
- Luggage compartment lid latch
- Ambient lighting module (if equipped)
- Ambient lighting switch (if equipped) (part of the passenger air bag deactivation [PAD] indicator)
- Ambient lighting lamps (if equipped)

The interior lighting system may consist of up to 3 subsystems:
- Courtesy lamps
- Demand lamps
- Ambient lighting (if equipped)

The courtesy lamps are controlled by the SJB. The courtesy lamp subsystem consists of the interior/map lamps. The SJB turns on the courtesy lamps when a door is opened. The courtesy lamps also turn on when an unlock signal is received from the remote keyless entry (RKE) transmitter.

The demand lamps system consists of the front dome map lamps. The SJB controls the demand lamps by providing ground for the battery saver relay.

The ambient lighting system consists of the ambient lighting switch, the ambient lighting module, and the harness with hard-wired LEDs all located within the floor console. The ambient lighting is turned on by the headlamp switch. Whenever the parking lamps are on, power is supplied to the ambient lighting module. The ambient lighting switch is used to cycle the LEDs through 7 different color combinations or to turn the ambient lighting off. The ambient lighting module provides the necessary voltage to the LEDs to illuminate the cup holders (front and rear) and the front and rear footwell areas.
