Diagnostic Testing: Notes

WARNING: This page is about a different car, the 1995 Saab 9000. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For component location information, refer to the THEORY/OPERATION - 3.0L V6 article.

CAUTION: If ECM replacement is instructed in following testing, always ensure ECM harness connector and ground circuit are okay. If either are suspect, repair and repeat testing to confirm ECM malfunction.

CAUTION: Service all DTCs in numerical order, starting with the lowest number first.
