Interior Lighting

Interior Lighting

The interior lighting system consists of the following:

NOTE: For super and crew cab vehicles, the front interior lamp is part of the overhead console.

- Interior lamps
- Cargo lamp
- Running board lamps
- Illuminated vanity mirrors
- Engine compartment lamp
- Door ajar switches
- Instrument panel dimmer switch
- Steering Column Control Module (SCCM)
- Body Control Module (BCM)

The interior lighting system consists of 2 subsystems:

- Courtesy lamps
- Demand lamps

Battery Saver

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

The BCM provides automatic shut-off of the courtesy and demand lamps after a time-out period in order to save battery voltage. A timer in the BCM is started when the ignition is turned OFF and all the doors are closed. When 10 minutes have elapsed, the voltage is automatically shut off to the lamps by the BCM.

The timer restarts (and voltage is restored if the BCM had the voltage disabled) if any of the following occurs:

- The ignition state is changed to any state other than OFF.
- Any door becomes ajar.
- The UNLOCK button of the Remote Keyless Entry (RKE) transmitter is pressed.
- A valid keypad code is entered.
- The instrument panel dimmer switch is pressed

Courtesy Lamps

The courtesy lamp subsystem consists of the door ajar switches (integrated into the door latches), the interior dome lamps, the cargo lamp, the running board lamps, the instrument panel dimmer switch, the SCCM, and the BCM.

Illuminated Entry

The illuminated entry requests the dimmable backlighting, the parking lamps and the courtesy lamps to illuminate when the ignition is OFF and a door is opened, the RKE transmitter UNLOCK button is pressed, or the vehicle is unlocked using the keyless entry keypad. If no doors are open, the illuminated entry requests the lamps off after 25 seconds have elapsed, the ignition is switched out of OFF, the RKE transmitter LOCK button is pressed, or the vehicle is locked using the keyless entry keypad.

Interior Lighting Delay

The interior lighting delay feature provides temporary illumination of the dimmable backlighting, the parking lamps and the courtesy lamps after the doors are opened and then closed. The interior lighting delay feature keeps the lamps on for a period of 25 seconds after all the doors are closed. If during the 25-second delay time the BCM detects that the ignition has been switched out of OFF, or if the vehicle is locked using the RKE transmitter or the keyless entry keypad, the lamp illumination is discontinued.

Illuminated Exit

The illuminated exit requests the dimmable backlighting, the parking lamps, and the courtesy lamps to illuminate for 25 seconds after all doors are closed and the ignition is turned OFF. The illuminated exit deactivates when the ignition is transitioned out of the OFF state, a door 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.

Demand Lamps

The demand lamps subsystem consists of the map/reading lamps, the vanity mirror lamps located in the visors and the engine compartment lamp. The BCM energizes the battery saver relay to supply voltage to the demand lamps when the battery saver feature is not active.
