Ignition Systems: Notes

WARNING: This page is about a different car, the 2003 Saturn Ion 3, 2003 Saturn Ion 2, and 2003 Saturn Ion 1. 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 frontprobe terminals. Do not use paper clips or other substitutes as they can damage terminals and cause incorrect measurements.

NOTE: Manufacturer does not provide testing procedures for many individual systems and components. For ignition system or component testing not listed, perform related DTC testing procedure. See DIAGNOSTIC TROUBLE CODE DEFINITIONS in SELF-DIAGNOSTICS - 2.2L ION article.
