Circuit/System Verification

  1. Start the engine. The engine should start and run.
  2. Monitor the Ignition Mode parameter. The parameter should transition from Bypass to IC when the engine is cranking or running.
  3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
