Engine faults are generated by the by the Yanmar engine Electronic Control
Unit (ECU) to identify an electrical system malfunction (fault) pertaining to the
engine during operation. The fault IDs conform to SAE J2012 standards. When
a fault occurs a code for the active fault will appear along the bottom of the TDM
display/controller screen. If more than one fault is active, their codes will scroll
across the bottom of the TDM display/controller screen one-by-one. Depending
on the severity of the fault, a STOP icon may also be displayed.
Recent faults can be viewed via the TDM display/controller. A code appears
after each fault indicating which controller generated the fault. For example:
P1455:EN is a DPF pressure sensor fault generated by the Yanmar engine ECU.
Refer to the Yanmar TNV (Tier 4) Series Troubleshooting Manual
