For 1990-2009 cars only

Vehicles with the optional remote keyless entry (RKE) system have interior lighting controlled by the body control module (BCM).

This vehicle uses a delayed interior lighting system.

The system functions as follows:

    • The dome lamps will illuminate when any door is opened.
    • The dome lamps will remain on for 20 seconds after the last door is closed.
    • The delay is canceled and the dome lamps will go out when the ignition switch is turned to the ON position.
    • The illuminated entry function will not operate when the dome lamp defeat switch is in the OFF position.
    • The interior lighting system is protected from battery rundown by the retained accessory power (RAP) system. The RAP system functions by shutting down interior lights after 10 minutes (when ignition is OFF).
