Normal Operation

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

The stoplamp switch is supplied battery voltage through circuit 10 (LG/RD) from the smart junction box (SJB). When the brake pedal is applied, the stoplamp switch allows voltage to flow through circuit 511 (LG). Circuit 511 (LG) provides voltage to the high mounted stoplamp and SJB, which in turn provides voltage to the LH and RH rear lamps.
