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
- Instrument panel dimmer switch
- Interior lamps
- Vanity mirror lamps
- Door ajar switches (integrated into the door latch)
- Liftgate ajar switch (integrated into the liftgate latch)
- Liftgate glass ajar switch (integrated into the liftgate glass latch)
- Ambient lighting switch (if equipped)
- Ambient lighting module (if equipped) (mounted under the bottom of the floor console finish panel storage tray)

The interior lighting system may consist of up to 3 subsystems:

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

Courtesy Lamps

The courtesy lamp subsystem consists of the ajar switches, the interior dome lamps, the instrument panel dimmer switch and the SJB. The SJB supplies voltage to the courtesy lamps when the SJB receives the required input.

Demand Lamps

The demand lamps are provided voltage from the battery saver relay (internal to the SJB). The demand lamps subsystem consists of the map/reading lamps, cargo lamp 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 ambient lighting system consists of the ambient lighting switch, the ambient lighting module, and the harness with hard-wired 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 Mode

The interior courtesy lamps turn on when the instrument panel dimmer switch is rotated to the DOME LAMP position. When the instrument panel dimmer switch is not in the DOME LAMP position, the interior courtesy lamps are activated by other interior lighting features.

The cargo lamp does not illuminate when the cargo lamp switch is in the OFF position when the courtesy lamps are activated. For the cargo lamp to illuminate in conjunction with the courtesy lamps, the cargo lamp switch must be in the DOOR position.

Dome Defeat

When the instrument panel dimmer switch is in the DOME 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 DOME DEFEAT position before the 25-second timer expires, the courtesy lamps are illuminated until the 25-second timer has elapsed.

Interior Lighting Delay

When the dome defeat feature is not active, 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, the parking lamps and the dimmable backlighting 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 switched out of OFF, or if the vehicle is locked using the RKE transmitter or the keypad, the courtesy lamp illumination is discontinued.

Illuminated Entry

The illuminated entry requests the courtesy lamps, the parking lamps and the dimmable backlighting to illuminate when the ignition is OFF and either the Remote Keyless Entry (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 keypad.

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 becomes ajar.
- 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

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, liftgate and liftgate window are closed. When 10 minutes has elapsed, voltage is automatically shut off to the lamps by the SJB. While the SJB has voltage disabled, if the ignition is turned to any position other than OFF, any door, liftgate or liftgate window becomes ajar, the UNLOCK button of the Remote Keyless Entry (RKE) transmitter is pressed or the instrument panel dimmer switch is rotated to the DOME LAMP position, the SJB restores voltage and starts the timer again.
