PINPOINT TEST H: THE HEADLAMPS ARE INOPERATIVE WITH AUTOLAMPS ON

H1-H3:

Normal Operation
When the smart junction box (SJB) has determined that the ambient light level is low enough to require the exterior lamps on, the SJB energizes an internal relay which routes voltage to the headlamps through circuit 15 (RD/YE).

Possible Causes
- Circuit 15 (RD/YE) open
- SJB
