Ground Circuits Testing

Before checking the ground circuit from the faulty component all the way to the ground stud, check the circuit from the splice pack to ground by testing some of the other subsystems grounded by the same splice pack. If the other subsystems function properly, it is most likely that the path from the splice pack to ground is good (or at least one of the paths is good with redundantly grounded splice packs).

Left Rear Body Ground Splice Pack
Location: See Power and Ground Distribution/Ground Distribution. Power and Ground Distribution

The left rear body splice pack provides a ground path for the rear body, decklid, and hatch harnesses. If one of the following systems is operating normally, the ground circuit is most likely good.
- License and cargo lamps
- Left-hand taillamps
- Fuel pump

Check for OPENS/SHORTS.

Repair as needed.
