Ground Circuits Testing

Before checking the ground circuit from the switch 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 ground splice packs).

I/P Splice Pack #1
Location: Taped to harness behind I/P cluster.

The systems grounded by I/P Splice Pack #1 are grounded redundantly with I/P Splice Pack #2 at ground point location D (I/P chassis ground). If one of the following systems is operating normally, the ground circuit is most likely good.
^ Transaxle shift program switch
^ I/P dimmer
^ Cruise control
^ Headlamp switch
^ Cigar lighter element

Check for OPENS/SHORTS.

Repair as needed.

Left Rear Body Ground Splice Pack
Location: Behind left rear shock tower.

The Left Rear Body Ground Splice Pack provides a ground path for the rear body and liftgate 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.
