Normal Operation

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The smart junction box (SJB) sends a reference signal to the multifunction switch through circuit 196 (DB/OG). When the multifunction switch is placed in the flash-to-pass position, the signal is routed to circuit 570 (BK/WH). When the SJB detects a request for the FLASH-TO-PASS, the SJB sends voltage through circuits 1779 (DB/LG) (RH headlamp) and 1724 (WH/LG) (LH headlamp) to the high beam headlamps.
