Test F: The Flash-To-Pass Feature Is Inoperative

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

F1-F3:

F4:

Normal Operation
The smart junction box (SJB) sends a reference signal to the multifunction switch through circuit CLF27 (GN/BN). When the multifunction switch is placed in the FLASH-TO-PASS position, the voltage signal is routed to ground. When the SJB detects a request for the flash-to-pass, the SJB sends voltage to the high beam headlamps.

Possible Causes
- Circuit CLF27 (GN/BN) open
- Multifunction switch
- SJB
