Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.
  1. Ignition 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 1 or A 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. Verify that a test lamp does not illuminate between the control circuit terminal 2 or B and ground.
    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.
    • 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 a digital multimeter (DMM) black lead to the control circuit terminal 2 or B and the red lead to B+. Set the DMM on the diode setting. Command the Camshaft Position Actuator Solenoid On and Off with a scan tool.
  7. Verify the DMM display transitions from OL when commanded Off to less than 1 V when commanded On.
    • If the DMM does not transition as specified 
    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 DMM transitions as specified 
  8. Test or replace the Q6 Camshaft Position Actuator Solenoid Valve.
