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 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 CLS30 (VT/WH) to the rear and front parking lamps. Ground is provided to the rear parking, liftgate and license plate lamps through circuit GD149 (BK/GY) or circuit GD151 (BK/GN). Ground is provided to the front parking and side marker lamps through circuit GD120 (BK/GN) or circuit GD123 (BK/GY).

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Bulb Holder
- Liftgate lamp
- Liftgate release handle
- Headlamp assembly
