Circuit/System Testing

WARNING: This page is about a different car, the 2016 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition/Vehicle Off and all vehicle systems Off, disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve. It may take up to 2 min for all vehicle systems to power down.
  2. Test for less than 5 Ω between the low reference circuit terminal 2 or B and ground.
    • If 5 Ω or greater 
    1. Ignition/Vehicle 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/Vehicle in Service Mode.
  4. Verify the appropriate scan tool parameters listed below do not display Malfunction:
    • Camshaft Position Actuator Solenoid Valve Control Circuit Open Test Status
    • Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage Test Status
    • If Malfunction is displayed 
    1. Ignition/Vehicle Off, disconnect the harness connector at the K20 Engine Control Module, ignition On/Vehicle in Service Mode.
    2. Test for less than 1 V between the control circuit terminal 1 or A at the Q6 Camshaft Position Actuator Solenoid Valve harness connector and ground.
      • If greater than 1 V, repair the short to voltage on the circuit.
      • If less than 1 V
    3. Test for less than 2 Ω in the control circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω
    4. Test for 7-12 Ω between the control circuit terminal 1 or A and the low reference circuit terminal 2 or B at the Q6 Camshaft Position Actuator Solenoid Valve.
      • If not between 7-12 Ω, test or replace the Q6 Camshaft Position Actuator Solenoid Valve.
      • If between 7-12 Ω, replace the K20 Engine Control Module.
    • If Malfunction is not displayed 
  5. Ignition/Vehicle Off, disconnect the X2 harness connector at the K20 Engine Control Module.
  6. Test for infinite resistance between the control circuit terminal 1 or A and ground.
    • If less than infinite resistance 

      Repair the short to ground on the control circuit.

    • If infinite resistance 
  7. Test for infinite resistance between each terminal of the Q6 Camshaft Position Actuator Solenoid Valve and the valve housing.
    • If less than infinite resistance 

      Test or replace the Q6 Camshaft Position Actuator Solenoid Valve.

    • If infinite resistance 
  8. Reconnect all components and clear all DTCs.
  9. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
  10. Verify the DTC does not set.
    • If the DTC sets 

      Replace the K20 Engine Control Module.

    • If the DTC does not set 
  11. All OK.
