PINPOINT TEST H: THE HEADLAMPS ARE INOPERATIVE WITH AUTOLAMPS ON

Test H1-H2:

Test H2-H3:

Normal Operation
When the ambient level has reached a point (determined by the internal programming of the vehicle security module), 2 internal relays are energized to supply power to the exterior lamps. Circuit 196 (DB/OG) supplies power to the internal headlamp relay, which in turn supplies power to circuit 15 (RD/YE) when energized.

Possible Causes
- Circuit 15 (RD/YE) open
- Circuit 196 (DB/OG) open
- Vehicle security module
