This code will set as an indicator that the ECM is in learn mode and not as a fault indicator. Any malfunction that causes a no-crank condition will prevent DTC P0633 from clearing. This DTC will clear upon a successful engine crank and start.
Prior to diagnosing the DTC or replacing the ECM, ensure that all power moding, VTD and engine cranking systems are operating correctly.
