SC1

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 LIP cluster.


The systems grounded by I/P Splice Pack #1 arc grounded redundantly with I/P Splice Pack #2 at ground point location D (LIP 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.


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 D (I/P chassis ground). If one of the following systems is operating normally the ground circuit is most likely good.


^ Fuel 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.
