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 M98 Intake Manifold Runner Valve Actuator. It may take up to 2 min for all vehicle systems to power down.
  2. Test for less than 5 Ω between the ground circuit terminal 2 and ground.
    • If 5 Ω or greater 
    1. Ignition Off.
    2. Test for less than 2 Ω in the circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, repair the high resistance in the ground connection.
    • Go to next step: If less than 5 Ω 
  3. Ignition On.
  4. Verify there is between 9 - 11 V between the signal circuit terminal 5 and ground.
    • If 9 V or less 
    1. Ignition Off, disconnect the harness connector at the K20 Engine Control Module.
    2. Test for infinite resistance between the signal circuit and ground
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance.
    3. Test for less than 2 Ω in the signal 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 11 V or greater 
    1. Ignition Off, disconnect the harness connector at the K20 Engine Control Module, ignition On.
    2. Test for less than 1 V between the signal 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.
    • Go to next step: If between 9 - 11 V 
  5. Replace the M98 Intake Manifold Runner Valve Actuator.
