Service Mode Operation: Notes

WARNING: This page is about a different car, the 1996 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: PCM, IPC, ACM, SDM, TCS, RSS, 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 trouble codes have been displayed, service mode can be used to clear codes and exit diagnostics or individually perform other tests on different systems.
