Ground Circuits Testing
Use the following Diagnosis to determine if malfunction is caused by instrument panel cluster, wiring or another component. If cluster is the 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.
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.
