SC2

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.

^ 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.


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:


^ Left and right front solenoids

^ Driver buckle switch

^ Sensing and diagnostic module (SDM)

^ 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:

^ Coolant level switch

^ Washer pump

^ All right side forward lamps Check for OPENS/SHORTS. Replace as needed.
