Diagnostic Procedures

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform diagnostic system check - engine controls. See DIAGNOSTIC SYSTEM CHECK - ENGINE CONTROLS  under SELF-DIAGNOSTIC SYSTEM. After performing diagnostic system check - engine controls, go to next step.
  2. Install a scan tool. Turn ignition on, with engine off. Are any other DTCs set? If yes, go to DIAGNOSTIC TROUBLE CODE DEFINITIONS . If no, go to next step.
  3. Start engine. Observe the CMP Resync Counter parameter with the scan tool. Is the CMP Resync Counter parameter incrementing? If yes, go to next step. If no, go to DIAGNOSTIC AIDS .
  4. Turn ignition off. Disconnect the ICM. Connect a jumper wire from each terminal, except the CMP sensor signal circuit, in the ICM harness connector to the corresponding terminal at the ICM with the Connector Test Adaptor Kit (J-35616-A). Start engine. Observe the CMP Resync parameter on the scan tool. Did the CMP Resync Counter parameter stop incrementing? If yes, go to next step. If no, go to step  6.
  5. Turn ignition off. Test for an intermittent and for a poor connection at the ICM. Did you find and correct the condition? If yes, go to step  9. If no, go to step  7.
  6. Disconnect the ECM. Test for an intermittent and for a poor connection of the camshaft position signal circuit at the ECM connector. Did you find and correct the condition? If yes, go to step  9. If no, go to step  8.
  7. Replace ICM. After replacing ICM, go to step  9.
  8. Turn ignition off. Replace ECM. Perform ECM relearn procedure. See ELECTRONIC CONTROL MODULE REPROGRAMMING  under PROGRAMMING. After replacing ECM, go to next step.
  9. Using scan tool, clear DTCs. Turn ignition off for 30 seconds. Operate vehicle within the conditions for running the DTC. See CONDITIONS FOR RUNNING DTC . You may also operate vehicle within the conditions observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition? If yes, go to step  2. If no, go to next step.
  10. With a scan tool, observe the stored information, Capture Info. Does the scan tool display any DTCs that you have not diagnosed? If yes, see DIAGNOSTIC TROUBLE CODE DEFINITIONS . If no, system is okay.
