Diagnostic Aids

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Inspect the KS for physical damage. A KS that is dropped or damaged may cause a DTC to set.
Inspect the KS for proper installation. A KS that is loose or over torqued may cause a DTC to set. The KS should be free of thread sealant.
The KS mounting surface should be free of burrs, casting flash, and foreign material.
