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 smart junction box (SJB) provides voltage to the digital transmission range (TR) sensor, or the reversing lamp switch, through circuit CBP20 (YE/VT). When the transmission is placed in REVERSE, the digital TR sensor, or the reversing lamp switch, routes the voltage to the reversing lamps through circuit CET41 (BN/YE).
