Service Mode Operation: Notes

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

NOTE: IPC, ACP, SIR and TCS systems can also be tested in SERVICE MODE. Only information related to PCM diagnosis is covered in this article.

After PCM diagnostic trouble codes have been displayed, SERVICE MODE can be used to exit diagnostics or individually perform other tests on different systems.
