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, 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 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 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.
