Keyless Entry Interior Illumination

When the driver uses the door key in order to unlock the doors, the Body Control Module (BCM) receives a door unlock signal. The BCM must have inputs that indicate that the ignition switch is OFF, the courtesy lamp switch is OFF and all the doors are closed. The BCM will then activate the interior lamps. The courtesy lamps will remain on, approximately 10 seconds after the door is closed. The BCM will then turn them off through the theater dimming feature. If the door locks are activated to the LOCK position, or if the ignition switch is turned to either the ON or START position the courtesy lamps will turn off immediately.

On vehicles with a Remote Control Door Lock Receiver (RCDLR), when the RCDLR module receives a door unlock command from the Remote Keyless Entry (RKE) transmitter, the RCDLR module will send a class 2 message to the Body Control Module (BCM) indicating that an UNLOCK command has been received. The BCM will keep the courtesy lamps on approximately 10 seconds and then turn them off through the theater dimming feature. If the door locks are activated to the LOCK position, the courtesy lamps will deactivate immediately. When the ignition switch is turned to either the ON or RUN position the courtesy lamps will deactivate in approximately 1 second.

On vehicles without a RCDLR when the BCM receives a door unlock command from the Remote Keyless Entry (RKE) transmitter, the BCM will keep the courtesy lamps on approximately 10 seconds and then turn them off through the theater dimming feature. If the door locks are activated to the LOCK position, the courtesy lamps will deactivate immediately. When the ignition switch is turned to either the ON or RUN position the courtesy lamps will deactivate in approximately 1 second.
