Normal Operation

WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

The multifunction switch receives power from the headlamp switch through circuit 15 (RD/YE). When the multifunction switch is placed in the HIGH BEAM position, voltage is routed to the high beam relay coil through circuit 275 (YE). When the high beam relay coil receives battery voltage from circuit 275 (YE), the high beam relay is energized. Battery voltage received from within the central junction box (CJB) is then routed to circuit 12 (LG/BK) via CJB fuse 35 (20A) and then to the high beam headlamps. Circuit 57 (BK) is the ground circuit for the headlamps and relay.
