Service Mode Operation: Notes
WARNING: This page is about a different car, the 1994 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
In Service Mode, the PCM, IPC, ACP, SIR, TCS and RTD systems can be tested. Only information related to IPC diagnosis and testing is given in this article.
After trouble codes have been displayed, service mode can be used to individually perform several tests for each trouble code displayed. Service mode can also clear all trouble codes and then exit diagnostics.
