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
- Cargo lamp
- Glove compartment lamp
- Vanity mirror lamps
- Door ajar switches
- Puddle lamps

The interior lighting system consists of 2 subsystems:

- Courtesy lamps
- Demand lamps

Courtesy Lamps

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

Demand Lamps

The demand lamps are controlled by the SJB. The demand lamps subsystem consists of the glove compartment lamp, all map/reading lamps, and the vanity mirror lamps.

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. If during the 25-second delay, the SJB detects that the ignition has been turned to RUN, ACC or START position, or if the vehicle is locked using the Remote Keyless Entry (RKE) transmitter, the courtesy lamp illumination is discontinued.

Illuminated Entry

The illuminated entry requests the courtesy lamps and the dimmable backlighting to illuminate when the ignition is off and the RKE transmitter UNLOCK button is pressed. The illuminated entry requests the courtesy lamps off after 25 seconds have elapsed, the ignition is switched to ON, or when the RKE transmitter LOCK button is pressed.

Illuminated Exit

The illuminated exit illuminates the courtesy lamps for 25 seconds when all doors are closed and the ignition key is removed from the ignition lock cylinder. The illuminated exit deactivates when any door becomes ajar, the ignition key is inserted into the ignition lock cylinder, or 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.

Battery Saver

The battery saver is internal to the SJB and provides automatic shut off of the demand lamps (vanity lamps, map lamps and glove compartment lamp) and courtesy lamps after a 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. When the time-out period for the lamps has elapsed, the voltage is automatically shutoff to the lamps by the battery saver. While the battery saver has voltage disabled, if the ignition is turned to any position other than off, any door or liftgate/glass becomes ajar, the UNLOCK button of the Remote Keyless Entry (RKE) transmitter is pressed, the instrument panel dimmer switch is placed in the DOME position, the battery saver 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 if the dome lamp is off and the liftgate/liftgate glass is closed = 10 minutes
- Courtesy lamps if the dome lamp is on or the liftgate/liftgate glass is open = 30 minutes
- Demand lamps = 30 minutes
