Keyless Entry Interior Illumination

KEYLESS ENTRY INTERIOR ILLUMINATION

When you use the door key in order to unlock the doors, the body control module (BCM) receives a door unlock signal. The BCM will then activate the interior lamps, provided the BCM has input signals indicating the following conditions:
- The ignition switch is OFF
- The courtesy lamp switch is OFF
- All the doors are closed

If the door locks are activated to the LOCK position, or if the ignition switch is turned to either the RUN or CRANK position the courtesy lamps will turn off immediately. Otherwise the courtesy lamps will remain on for approximately 40 seconds after the door is closed. The BCM will then turn the courtesy lights off through the theater dimming feature.

If you use the remote function actuator transmitter in order to unlock the doors or the trunk, or if you press the panic button, the BCM will keep the courtesy lamps on for approximately 15 seconds. If the door locks are activated to the UNLOCK or LOCK position, or if the ignition switch is turned to either the RUN or CRANK position, the courtesy lamps will turn off immediately.

The BCM will also keep the courtesy lamps on for approximately 40 seconds after an alarm event is completed.

The courtesy lamps in Special Equipment Option (SEO) vehicles may be disabled by using the emergency vehicle interior lamp switch, called surveillance mode.
