Courtesy Lamps

The courtesy lights come on when any door is opened, when the interior lamp switch is in the ON position, or when activated by unlocking the doors using the keyless entry transmitter (illuminated entry). The courtesy lights will also light for approximately 25 seconds and fade out when the key is removed from the ignition switch with all doors closed.

Battery positive voltage (B+) is applied at all times through the IP fuse block CTSY LP/PWR MIR Fuse 6A via CKT 640 (ORN) through the body control module (MALL) to the courtesy lights via CKT 1732 (ORN). When the MALL receives an input from a door being opened, the interior lamp switch being turned ON, or the doors being unlocked using the keyless entry transmitter, it provides a ground through CKT 156 (WHT) for the courtesy lamps, and the courtesy lamps then light.

When the courtesy lights are activated by opening and closing a door, the courtesy lights will remain on for approximately 25 seconds and fade out after all doors have been closed. If the ignition switch is turned to START or RUN within the 25 seconds, the lights will immediately begin to fade out. If a door is left open, the MAIL will remove battery positive voltage (B+) to the courtesy lights after 10 minutes. When the courtesy lights are activated by the interior lamp switch, the lights will remain on as long as the interior lamp switch is in the ON position. When the courtesy lights are activated by unlocking the doors using the keyless entry transmitter, the lights will remain on for approximately 40 seconds. If the doors are locked using the keyless entry transmitter within the 40 seconds, the lights will immediately begin to fade out.
