PINPOINT TEST G: THE AUTOLAMPS ARE INOPERATIVE

G1-G4:

G4-G5:

Normal Operation
The smart junction box (SJB) sends a reference signal to the light sensor through circuit 1416 (YE/WH). When the headlamp switch is placed in the AUTOLAMPS ON position, the SJB monitors the ambient light conditions based on the input received from the light sensor. When the ambient light level has reached a point (determined by the internal programming of the SJB), the SJB provides voltage to the headlamps, parking and license plate lamps.

Possible Causes
- Circuit 1416 (YE/WH) short to ground
- Light sensor
- SJB
