PINPOINT TEST F: THE AUTOLAMPS ARE INOPERATIVE

F2-F3:

Normal Operation
When the smart junction box (SJB) detects the headlamp switch in the AUTOLAMPS ON position, the SJB monitors the light sensor input. The light sensor determines the amount of light based on the input received from the ambient sky conditions. When the ambient 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
- Light sensor
- SJB
