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

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

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 energizes the high beam relay (integral to the SJB), which supplies voltage to the headlamps.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Multifunction switch
- SJB
