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:

- Door ajar switches (part of the door latch)
- Instrument panel dimmer switch
- Interior/map lamps
- Liftgate ajar switch
- Liftgate/Trunk Module (LTM) (if equipped)
- Puddle lamps
- SJB
- Vanity mirror lamps
- Ambient lighting module (if equipped) (mounted under the bottom of the floor center console)
- Ambient lighting switch (if equipped)

The interior lighting system consists of 3 subsystems:

- Courtesy lamps
- Demand lamps
- Ambient lighting (if equipped)

Courtesy Lamps

The courtesy lamps are controlled by the SJB. The courtesy lamp subsystem consists of the ajar switches, interior lamps, instrument panel dimmer switch, LTM (if equipped), and the puddle lamps. The SJB supplies voltage to the courtesy lamps when the SJB receives the required input.

Demand Lamps

The demand lamps are also controlled by the SJB via the battery saver relay. The demand lamps subsystem consists of the map/reading lamps, and the LH and RH vanity mirror lamps. The SJB energizes the battery saver relay to supply voltage to the demand lamps.

Ambient Lighting

The SJB and the LTM (if equipped) set DTCs if certain circuit failures exist with the interior lighting system.

The ambient lighting system consists of the ambient lighting switch, the ambient lighting module, and the harness with hardwired LEDs located within the front and rear footwells, the floor console cup holders, the storage tray and the storage bin. The ambient lighting is powered on when the ignition key is in the RUN or ACCESSORY position. 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, the storage tray bin and the front and rear footwell areas.

Interior Lighting Delay

The interior lighting delay feature provides temporary illumination of the courtesy lamps after the doors are opened and then closed. The interior lighting delay feature keeps the courtesy lamps on for a period of 25 seconds after all the doors, or the liftgate is closed. If during the 25-second delay time the SJB detects that the ignition has been turned out of OFF, or if the vehicle is locked using the Integrated Keyhead Transmitter (IKT) or the keypad, the courtesy lamp illumination is discontinued.

Illuminated Entry

The illuminated entry requests the courtesy lamps to illuminate when the ignition is OFF and either the IKT transmitter UNLOCK button is pressed, or the vehicle is unlocked using the keypad or driver door lock cylinder. The illuminated entry requests the courtesy lamps off after 25 seconds have elapsed, the ignition is switched out of OFF, the IKT transmitter LOCK button is pressed, or the vehicle is locked using the keypad.

Illuminated Exit

The illuminated exit requests the courtesy lamps to illuminate for 25 seconds when all doors are closed and the ignition key is removed from the ignition lock cylinder. The illuminated exit deactivates when the ignition key is inserted into the ignition lock cylinder, a door or the liftgate becomes ajar, or 25 seconds have elapsed.

Theater Lighting

The theater lighting feature ramps-up the courtesy lamps over 0.7 seconds when courtesy lamp activation is requested. The theater lighting feature ramps-down the courtesy lamps over 1.7 seconds when interior lighting deactivation is requested by any feature other than the panic alarm or battery saver.
