PINPOINT TEST F: THE FLASH-TO-PASS FEATURE IS INOPERATIVE

F1-F3:

F3-F4:

Normal Operation
The smart junction box (SJB) sends a voltage reference signal to the multifunction switch through circuit 1395 (RD/PK). When the flash-to-pass feature is activated, the multifunction switch routes the signal back to the SJB. The SJB then provides voltage to the high beams.

Possible Causes
- Circuit 1395 (RD/PK) open
- Multifunction switch
- SJB
