Circuit/System Testing

WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition Off and all vehicle systems Off, disconnect the appropriate harness connector at the Q6 camshaft position actuator solenoid valve. It may take up to 2 minutes for all vehicle systems to power down.
  2. Test for less than 5 Ω between the low reference circuit terminal 2 and ground.
    • If 5 Ω or greater 
    1. Ignition Off, disconnect the harness connector at the K20 engine control module.
    2. Test for less than 2 Ω in the low reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit
      • If less than 2 Ω, replace the K20 engine control module
    • If less than 5 Ω 
  3. Ignition On.
    4. NOTE:

    A test lamp must be used for this test. The control circuit is pulled-up to a low current voltage, 1.5-3.5 V on the control circuit is normal.

  4. Verify that a test lamp does not illuminate between the control circuit terminal 1 and ground.
    • If the test lamp illuminates 
    1. Ignition Off, disconnect the harness connector at the K20 engine control module, ignition On.
    2. Test for less than 1 V between the control circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit
      • If less than 1 V, replace the K20 engine control module
    • If the test lamp does not illuminate 
  5. Remove the test lamp.
  6. Connect the DMM black lead to the control circuit terminal 1. Connect the DMM red lead to B+. Command the Camshaft Position Actuator Solenoid On and Off with a scan tool. Verify the voltage changes.
    • If the voltage does not change 
    1. Ignition Off, disconnect the harness connector at the K20 Engine Control Module.
    2. Test for less than 2 Ω in the control circuit end to end.
    • If 2 Ω or greater, repair the open/high resistance or short to ground in the circuit.
    • If less than 2 Ω, replace the K20 Engine Control Module.
    • If the voltage changes 
  7. Test or replace the Q6 Camshaft Position Actuator Solenoid Valve.
