Diagnostic Aids
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Use Connector Test Adapter Kit (J-35616-A) for any test that requires probing the PCM harness connectors, electrical center fuse/relay cavities, component terminals and component harness connector. Using this kit will prevent damage caused by improper probing of connector terminals.
If the condition is intermittent, see INTERMITTENT CONDITIONS under SELF-DIAGNOSTIC SYSTEM.
