Circuit/System Verification

  1. Engine idling, command the IMT valve ON with a scan tool. The IMT valve vacuum actuator should move to the closed position.
  2. If the vehicle passes the Circuit/System Verification test, then operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records List.
