Service Mode Operation: Notes

WARNING: This page is about a different car, the 1998 Cadillac Eldorado and 1998 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: PCM, IPC, ACM, SDM, TCS, CVRSS, IRC, RFA, CCP and PHN systems can also be tested in service mode. Only information related to PZM diagnosis is covered in this article.

After PZM DTCs have been displayed, service mode can be used to clear DTCs and exit diagnostics or individually perform other tests on different systems.
