Machine faults are generated by the TDM display/controller to identify an
electrical system malfunction (fault) that occurs during machine operation. The
fault IDs conform to SAE J2012 standards. When a fault occurs, the bi-color
LED on the TDM display/controller panel will flash red and 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 screen. A code
appears after each fault indicating which controller generated the fault. For
example: C14C5:T1 is a PTO fault generated by the T1: TDM
