Courtesy/Illuminated Entry Lamps

The courtesy/illuminated lamps, may be manually turned on or off by placing the interior lamp switch in the ON or OFF position. When the driver places the dome lamp defeat switch in the OFF position, the courtesy/illuminated entry lamps will be disabled. If an outside door handle is lifted or a door is opened, the courtesy/illuminated entry lamps illuminate. After all the doors have been closed the courtesy/illuminated entry lamps will remain illuminated approximately 15 seconds. The courtesy/illuminated entry lamps will also turn on prior to any door being opened, and remain illuminated approximately 40 seconds when the driver removes the ignition key.

The courtesy/illuminated entry lamps, include two different groups of lamps. The first group includes these courtesy/illuminated entry lamps which are not individually controlled:
^ Dome lamps
^ Door courtesy lamps
^ I/P courtesy lamps

These lamps illuminate when a door jamb switch, courtesy lamp switch or a Remote Keyless Entry (RKE) command is received by the body control module (BCM).

The CTSY LP 15 A fuse in the engine wiring harness junction block, supplies battery positive voltage to the inadvertent power relay coil and switch circuits. The BCM provides a ground to control the inadvertent power relay. The normally open Inadvertent power relay switch closes and provides power to these courtesy lamps. When a courtesy lamp request input is received by the BCM, the BCM will energize the courtesy lamp relay. The normally open courtesy lamp relay switch closes, illuminating the lamps by grounding the courtesy lamp ground circuit to G203.

The BCM will immediately turn off the courtesy lamps if a door lock command is received with all the doors closed, or if the ignition switch is turned to either the ON or RUN position.

The second group includes these individually controlled lamps, each with a separate switch:
^ I/P compartment lamp
^ Map lamps
^ Reading lamps
^ Underhood lamp
^ Vanity mirror lamps

The CTSY LP 15 A fuse in the engine wiring harness junction block, supplies battery positive voltage to the inadvertent power relay coil and switch circuits. The BCM provides ground to energize the inadvertent power relay, which provides voltage to these lamps. Ground is provided to the I/P compartment lamp at G200. Ground is provided to the underhood lamp at G102. Ground is provided to all others at G203.
