PINPOINT TEST P: 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 (internal to the SJB). When the parking lamp relay is energized, voltage is sent through circuit CBP08 (GY/YE) to the rear and front parking lamps. Ground is provided to the rear parking and license plate lamps through circuit GD171 (BK/GY). Ground is provided to the front parking and side marker lamps through circuits GD121 (BK/YE) or GD123 (BK/GY).

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