MTU Fault Codes
A DGC-2020ES connected to a genset equipped with an MTU engine ECU tracks and displays the active
fault codes issued by the MTU engine ECU. Active MTU fault codes can be viewed through
BESTCOMSPlus
® by using the Metering Explorer to expand the MTU tree or through the front panel
display by navigating to METERING > ALARMS-STATUS > MTU FAULT CODES.
Each fault code is displayed with a fault description and the fault number. If the DGC-2020ES does not
have descriptive information about a fault number that was received, the fault description will display
as “NO TEXT AVAILABLE”. Fault codes displayed by the DGC-2020ES are listed in Table 34.
