Sedan

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).

Rear Body Splice Pack

Location: Above left rear shock tower.

The 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, CHMSL, cargo

^ Lamps

^ Fuel pump

^ Washer pump (Wagon)

Check for OPENS/SHORTS.

Repair as needed.

If this component is good go to the next item indicated on the "Complaint-Condition" chart.
