Grounds Circuits Testing

Before checking the ground circuit from the component all the way to the ground stud, check the circuit from the splice pack 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).

Left Body Ground Splice Pack
Location: Left side under driver's seat.
The left side body splice pack provides a ground path for the left side body harness. The left body ground splice pack has an integral ring terminal that grounds the splice pack directly to the body of the vehicle. If one of the following systems is operating normally, the ground circuit is most likely good.
^ Dome lamp
^ Power mirror
^ Sunroof
Check for OPENS/SHORTS.
Repair as needed.
