Interior Lighting

Interior Lighting

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

The SJB controls all of the interior lighting functions. The interior lighting system consists of the following components:

- SJB
- Liftgate/Trunk Module (LTM) (if equipped)
- Instrument panel dimmer switch
- Interior/map lamps
- Puddle lamps
- Cargo lamp
- Vanity mirror lamps
- Door ajar switches
- Liftgate ajar switch
- Ambient lighting switch (if equipped)

The interior lighting system consists of 2 subsystems:

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

Courtesy Lamps

The courtesy lamp subsystem consists of the interior dome lamps, the instrument panel dimmer switch, the overhead console lamps, the cargo lamp, and the puddle lamps (if equipped). The SJB supplies voltage to the courtesy lamps when the SJB receives the required input.

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 are closed. If during the 25-second delay time, the SJB detects that the ignition has been turned to the OFF position, or if the vehicle is locked using the Remote Keyless Entry (RKE) or the keyless entry keypad, the courtesy lamps are turned off.

Illuminated Entry

The illuminated entry requests the courtesy lamps, the parking lamps, the puddle lamps and the dimmable backlighting to illuminate when a door or liftgate is opened or when the ignition is OFF and either the RKE transmitter UNLOCK button is pressed, or the vehicle is unlocked using the keyless entry keypad. The illuminated entry requests the courtesy lamps off:

- after 25 seconds have elapsed.
- the ignition is switched out of OFF.
- the RKE transmitter LOCK button is pressed.
- the vehicle is locked using the keyless entry keypad or door lock cylinder.

Illuminated Exit

The illuminated exit requests the courtesy lamps, the parking lamps and the 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 liftgate becomes ajar.
- 25 seconds have elapsed.

Theater Lighting

The theater lighting option 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.

Demand Lamps

The demand lamps subsystem consists of the front map lamps, and the left and right vanity mirror lamps. The demand lamps are provided voltage from the battery saver relay (integrated into the SJB) when the battery saver relay is energized.

Ambient Lighting

The ambient lighting system consists of the ambient lighting switch, the ambient lighting module, and the harness with hardwired LEDs all located within the floor console. The ambient lighting is operational when the ignition key is in the ACC or RUN 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 LEDs illuminate the cup holders (front and rear) and the front and rear footwell areas.

Battery Saver

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

The SJB provides automatic shut-off of the demand lamps and courtesy lamps after a 10-minute time-out period in order to save battery voltage. A timer in the SJB is started when the ignition is turned to the OFF position and all the doors are closed. When the 10-minutes have elapsed, the voltage is disabled. The timer resets if any of the following occur:

- The ignition is turned to any position other than OFF.
- Any door becomes ajar.
- The UNLOCK button of the RKE transmitter is pressed.
- An unlock request from the door lock cylinder is received.
- A key is inserted into the ignition lock cylinder.
- A valid keypad code is entered.
- The instrument panel dimmer switch is placed in the DOME LAMP position.
- The headlamp switch is placed to the PARKING LAMPS or HEADLAMPS ON position.
- The multifunction switch is placed in the FLASH-TO-PASS position.
- The key is inserted into the ignition lock cylinder.
