Diagnostic Aids
WARNING: This page is about a different variant/trim than selected.
- Use the J 35616 Connector Test Adapter Kit for any test that requires probing the ECM harness connector or a component harness connector.
- Operating the throttle valve with the Throttle Position control function of the scan tool may cause additional DTCs to set. DO NOT attempt to diagnose DTCs set during this function.
- The scan tool has the ability to operate the throttle actuator control system using Special Functions. This function operates the throttle through the entire range in order to determine if the throttle body and system operate correctly.
- Inspect for a condition in which the throttle valve may have been held open.
- Inspect for conditions in which ice may have formed in the throttle bore.
- For an intermittent condition, refer to Intermittent Conditions .
