PINPOINT TEST O: ONE OR MORE PARKING, REAR OR LICENSE PLATE LAMPS IS INOPERATIVE

Normal Operation
When the headlamp switch is placed in the PARKING LAMPS ON position, the SJB provides a ground for the parking lamp relay coil (integral to the SJB). When the parking lamp relay is energized, voltage is routed through circuits CLS30 (VT) to the rear parking lamps and CLS30 (VT/WH) to the front parking lamps. Ground is provided to the rear parking and license plate lamps through circuits GD147 (BK/VT) and GD148 (BK/YE). Ground is provided to the front parking and side marker lamps through circuit GD120 (BK/GN).

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Bulb holder
- Rear lamp jumper harness
- Rear lamp assembly
- SJB
