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.

The parking lamp relay is integral to the smart junction box (SJB). When the headlamp switch is placed in the PARKING LAMPS ON position, the voltage is routed to the SJB through circuit CLS30 (VT/WH). When the parking lamp relay coil is energized, voltage is routed to the parking lamps through circuit CLS34 (GY), the trailer tow connector through circuit CBP20 (GN) and the instrument panel dimmer switch through circuit CBP01 (BU).
