Grounds Circuits Testing
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.
^ Perf/Norm switch
^ I/P dimmer
^ 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.
