Machine Faults
Machine faults are generated by the Toro Electronic
Controller (TEC) to identify an electrical system mal-
function (fault) that occurs during machine operation.
When a machine fault occurs, an audible alarm will
sound and the InfoCenter will display information about
the fault. Machine faults can be viewed via the InfoCen-
ter Diagnostic Screen Fault Viewer (Fig. 41). See Info-
Center Diagnostic Screen Fault Viewer in this chapter
for additional information.
For machines with gasoline engines, the Kubota Elec-
tronic Control Unit (ECU) can also generate electrical
faults. The faults generated by the ECU are specific to
the engine (see Engine Faults in this chapter for addi-
tional information).
The list below identifies the fault codes that are gener-
ated by the Toro Electronic Controller (TEC) to identify
an electrical system malfunction (fault) that occurred
during machine operation for revision D software. Use
the InfoCenter Display Diagnostics > Fault Viewer for
fault retrieval.
