Interior Lighting

Body Control Module (BCM) controls all interior light functions. BCM receives inputs from headlight dimmer switch, Remote Keyless Entry (RKE) unlock request, Vehicle Theft Security System (VTSS) and door ajar switches. Courtesy lights are illuminated when any door is opened with courtesy light switch not in dome off position, RKE unlock request or driver's door is unlocked using key on vehicles with VTSS. If any interior lights are left on for more than 8 minutes, BCM will automatically turn lights off to save battery power.
