Fault Codes

ated by the Toro Electronic Controller (TEC) to identify
an electrical system malfunction (fault) that occurred
during machine operation. Use the InfoCenter Display
for fault retrieval.
NOTE: The following list of fault codes identifies elec-
trical problems that typically will prevent normal ma-
chine operation. The InfoCenter Display will identify
existing faults if they should occur. For input problems,
