Pcm Power & Ground Check: Notes

WARNING: This page is about a different car, the 2003 Saturn LW200 and 2003 Saturn L200. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Do not insert test equipment probes into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal can cause a poor connection, which can result in system failures. Always use the Connector Test Adapter Kit (J 43907) to front probe terminals. Do not use paper clips or other substitutes as they can damage terminals and cause incorrect measurements.
