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:

- Ambient lighting module (if equipped) (mounted under the bottom of the floor center console)

- Ambient lighting switch (if equipped)

- 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 (Smart Junction Box)

- Vanity mirror lamps

The interior lighting system consists of 3 subsystems:

- Ambient lighting (if equipped)

- Courtesy lamps

- Demand lamps

Courtesy Lamps

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

Demand Lamps

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

Ambient Lighting

The ambient lighting system consists of the ambient lighting switch, the ambient lighting module, 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, parking lamps and dimmable backlighting 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 (Smart Junction Box) 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.

Dome Defeat

When the instrument panel dimmer switch is in the DEFEAT position, the illuminated entry and exit features do not turn the courtesy lamps on, however the timer for each feature is still active. If the instrument panel dimmer switch is moved out of the DEFEAT position before the 25-second timer expires, the courtesy lamps are illuminated until the 25-second timer has elapsed.

Illuminated Entry

The illuminated entry requests the courtesy lamps, parking lamps and dimmable backlighting to illuminate when the ignition is OFF and either the IKT (Integrated Keyhead Transmitter) transmitter UNLOCK button is pressed, 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 (Integrated Keyhead Transmitter) transmitter LOCK button is pressed, or the vehicle is locked using the keypad.

Illuminated Exit

The illuminated exit requests the courtesy lamps, parking lamps and dimmable backlighting 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 second 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.

Battery Saver

The SJB (Smart Junction Box) provides automatic shut-off of the demand lamps and courtesy lamps after a time-out period in order to save battery voltage. A timer in the SJB (Smart Junction Box) is started when the ignition is turned to the OFF position, and all the doors, and the liftgate are closed. When the time-out period for the lamps has elapsed, the voltage is automatically shut off to the lamps by the SJB (Smart Junction Box). While the SJB (Smart Junction Box) has voltage disabled, if the ignition is turned to any position other than OFF, any door, or the liftgate becomes ajar or the UNLOCK button of the IKT (Integrated Keyhead Transmitter) transmitter is pressed, a valid keypad code is entered, an unlock request from the cylinder is received, or the instrument panel dimmer switch is turned on, the SJB (Smart Junction Box) restores voltage and starts the timer again.

NOTE: Time-out is 1 minute if the vehicle has less than 80 km (50 miles).

The battery saver time-outs are as follows:

- Courtesy lamps = 10 minutes

- Demand lamps = 10 minutes
