PINPOINT TEST H: THE AUTOLAMPS ARE ON CONTINUOUSLY

H1-H2:

H2-H4:

Normal Operation
Under normal operation, when the headlamps are turned to the autolamp position, the headlamp switch sends a ground signal to the smart junction box (SJB) through circuit 1399 (DB/WH). When the light sensor detects a low light condition, ground from the sensor is sent to the SJB through circuit 1416 (YE/WH).

Possible Causes
- A short to ground in circuit 399 (DB/WH) or 1416 (YE/WH)
- Headlamp switch
- Smart junction box (SJB)
