PINPOINT TEST O: ONE OR MORE PARKING, REAR OR LICENSE PLATE LAMPS IS INOPERATIVENormal Operation - Explorer, Mountaineer
When the headlamp switch is switched to the PARKING LAMPS ON position, the smart junction box (SJB) provides a ground for the parking lamp relay coil (integrated into the SJB).
When the parking lamp relay is energized, voltage is routed through circuit CBP26 (BU/WH) to the rear and front parking lamps. Ground is provided to the LH rear parking and license plate lamps through circuit GD149 (BK/GY). Ground for the RH rear parking lamp is provided through circuit GD151 (BK/GN). Ground is provided to the LH front parking lamps through circuit GD120 (BK/GN). Ground is provided to the RH front parking lamps through circuit GD123 (BK/GY).
