    The ECM uses the main display module on the Monitoring System for showing diagnostic information to
    service personnel. Diagnostic information concerning the ECM is sent on the Cat Data Link to the
    Monitoring System. Service personnel must be familiar with the Monitoring System in order to troubleshoot
    the ECM.
