Ground Circuits Testing

Use the following "Diagnosis," to determine if malfunction is caused by instrument panel cluster, wiring or another Component. If cluster is malfunctioning component, then the cluster needs to be replaced.

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.
^ Automatic transaxle shift program switch
^ I/P dimmer
^ Cruise control
^ 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 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.
^ I/P cluster
^ 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 chart.
