Service Mode Operation: Notes
WARNING: This page is about a different car, the 1997 Cadillac Seville, 1997 Cadillac Eldorado, and 1997 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
PCM, IPC, ACM, SIR, 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.
