Courtesy/Illuminated Entry Lamps

When the Body Control Module (BCM) is in an active state (awake) it energizes the Delayed Interior Lamps (DIL) relay. When energized the delayed interior lamps relay supplies voltage to all of the interior lamps, including the illuminated entry lamps. The illuminated entry lamps are turned on when they receive a ground from the interior lamps relay. When the ignition is in the LOCK position the BCM will energizes the interior lamps relay under the following conditions:
^ Manually unlocking the driver side door lock.
^ A change in door jamb input status (open or close a door).
^ The use of the Remote Keyless Entry (RKE) to unlock the side doors.

When the delayed interior lamp relay and the interior lamp relay are energized the courtesy lamps will illuminate. The courtesy lamps/illuminated entry lamps include the following interior lamps:
^ The dome lamp.
^ The front side door courtesy lamps.
^ The roof rail courtesy lamps (depending on their individual switch positions).

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 20 seconds after the door is closed. If the ignition switch is turned to either the RUN or START position the courtesy lamps will turn off immediately.

When the driver uses the remote function actuator transmitter to unlock the doors, the BCM will keep the courtesy lamps on approximately 20 seconds. If the ignition switch is turned to either the RUN or START position the courtesy lamps will turn off immediately. When a door is opened and closed with the ignition not in RUN or START the courtesy lamps will illuminate for 20 seconds.
