DESCRIPTION & OPERATION
The headlight time delay system allows the headlights to remain on for 90 seconds after the vehicle is turned off. This provides time for the vehicle occupants to exit with illumination. The system is activated when the engine is running and the headlight switch is on. When the ignition is turned off and then, within 45 seconds the headlight switch is turned off, the delay will be activated. Headlights will turn off normally if headlight switch is turned off before engine. Delay system is connected to Body Control Module (BCM) and headlight switch. Time delay relay is located on the fuse panel junction block. A 30-amp fuse is located at position No. "H" in fuse panel.
TESTING
Note. Testing of the headlight time delay system requires using a Diagnostic Read-Out Box (DRB) or scan tool to check circuits connected to the body control computer. See the TESTS W/CODES - BODY CONTROL COMPUTER article in ENGINE section PERFORMANCE for complete Body Control Computer testing.
