Electrical System
Machine Faults
Machine faults are generated by the machine control-
lers to identify an electrical system malfunction (fault)
that occurs during machine operation. The fault IDs con-
form to SAE J2012 standards. When a fault occurs, the
bi--color LED on the display panel will flash red and a
code for the active fault will appear along the bottom of
the display screen. If more than one fault is active, their
codes will scroll across the bottom of the display screen
one--by--one.
