Normal Operation

WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.

When the headlamp switch is placed in the HEADLAMPS ON position, the multifunction switch routes voltage to the smart junction box (SJB) through circuit CLF18 (BU/WH). The SJB then routes voltage to the LH and RH low beams.
