Circuit/System Testing

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, open the hood to disable the Auto-Stop function.
  2. Ignition ON, verify the scan tool hood position parameter displays Open.
    • If the hood position does not display Open, refer to DTC P254F .
  3. Ignition OFF, disconnect the harness connector at the appropriate camshaft position (CMP) actuator solenoid.
  4. Ignition ON, verify that a test lamp illuminates between the ignition voltage circuit terminal 1 and ground.
    • If the test lamp does not illuminate, test the circuit for a short to ground or an open/high resistance. If the circuit tests normal and the ignition circuit fuse is open, test all the components connected to the ignition circuit and replace as necessary.
  5. Ignition ON, test for 1.5-3 V between the control circuit terminal 2 and ground.
    • If less than the specified range, test the control circuit for a short to ground, or an open/high resistance. If the circuit tests normal, replace the ECM.
    • If greater than the specified range, test the control circuit for a short to voltage. If the circuit/connections test normal, replace the ECM.
  6. Command the CMP actuator solenoid ON and OFF with a scan tool. The DMM should transition from 1.5-3 V when commanded OFF to less than 0.5 V, when commanded ON.
    • If the circuit voltage does not correspond to the specified values, replace the ECM.
  7. If all circuits/connections test normal, test or replace the CMP actuator solenoid.
