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).

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
^ Cruise module
^ Headlamp switch
^ Cigar lighter element
Check for OPENS/SHORTS.
Repair as needed.
If this component is good, go to the next item indicated on the Complaint-Condition Chart.

I/P Splice Pack #2
Location: Taped to harness behind I/P cluster.
The systems grounded by I/P Splice Pack #2 are grounded redundantly with I/P Splice Pack #1 at ground point location C (chassis ground). If one of the following systems is operating normally the ground circuit is most likely good.
^ Fuel level sensor
^ Park brake switch
^ Wiper motor
^ Radio
Check for OPENS/SHORTS.
Repair as needed.
If this component is good, go to the next item indicated on the Complaint-Condition Chart.

ABS/SIR Splice Pack
Location: Taped to harness behind I/P cluster
If the following system is operating normally, the fuse is most likely good:
^ Driver seat belt switch
^ ABS controller
Check for OPENS/SHORTS.
Replace as needed.
If this component is good, go to the next item indicated on the Complaint-Condition Chart.

Right Side Forward Lamp Splice Pack
Location: Behind right front headlamp.
The right side forward lamp splice pack provides a ground path for the right side forward lamp harness. If the following system is operating normally, the fuse is most likely good:
^ Washer pump
^ All right side forward lamps
Check for OPENS/SHORTS.
Replace as needed.
If this component is good, go to the next item indicated on the Complaint-Condition Chart.
