Diagnostic Aids

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the connector test adapter kit J 35616-A for any test that requires probing the following items:
  • The PCM harness connectors.
  • The electrical center fuse/relay cavities.
  • The component terminals.
  • The component harness connector.
Using this kit will prevent damage caused by the improper probing of connector terminals.

If DTC is determined to be intermittent, see INTERMITTENT CONDITIONS  under SELF-DIAGNOSTIC SYSTEM.
