    • If greater than 1.0 ohm, test the low reference for an open/high resistance. If the circuit tests normal replace the ECM.
  3. Connect a test lamp between the high control circuit and the low reference circuit .
  4. Ignition ON engine OFF.
  5. Command the CMP actuator solenoid ON and OFF. The test lamp should turn ON and OFF when changing between commanded states.
    • If the test lamp is always ON, test the high control circuit for a short to voltage. If the circuit tests normal replace the ECM.
