Machine Faults
The Machine Fault Table (page 7–33) identifies the fault codes that are
generated by the Toro Electronic Controller (TEC) to identify an electrical system
fault (malfunction) that occurred during the operation of the machine. Use the
InfoCenter display to view faults that have occurred since the faults were last
cleared from the InfoCenter; refer to
Faults Screen (page 7–16) .
The Yanmar engine ECU can also generate electrical faults. The faults generated
by the ECU are specific to the engine; refer to
Engine Faults (page 7–35) .
Note: Fault codes identify electrical problems that typically will prevent normal
machine operation. For fault codes that identify problems with TEC inputs (e.g.,
switches, sensors), use the InfoCenter display to check the different switch
positions before removing or replacing the component. Fault codes that identify
problems with TEC outputs (e.g., solenoid coils) might involve issues with the
wire harness or the actual output device.
Using Machine Faults
If an electrical fault is identified by the machine controllers (TEC and cutting unit
motors), the InfoCenter display will identify the fault code number and when
the fault occurred. An electrical fault can cause disruption in how the machine
functions but in some instances, the fault may occur with little, if any, change
in machine operation. The following suggestions should be considered when
using fault codes that are displayed.
•
If a fault code is displayed on the InfoCenter and machine operation remains
normal, continue to use the machine. The fault code number can be retrieved
in the future by using the InfoCenter faults screen.
•
If a fault code is displayed on the InfoCenter and machine operation has
changed, move the machine to a level surface, disengage the cutting units,
and turn the key switch to the O
FF
position. Leave the switch in the O
FF
position for 30 seconds and then start the machine. During this system reboot
process, the machine controllers often can reset the electrical components to
allow normal machine operation. Assuming that the fault code is no longer
displayed, continue to use the machine. The fault code number can be
retrieved in the future by using the InfoCenter faults screen.
•
There is the possibility that an electrical issue can result with several fault
codes being generated. For example, a broken wire or damaged fuse would
prevent operation of a cutting unit motor and multiple fault codes could be
displayed. Reviewing the fault code descriptions should suggest possible
causes for the circuit problem. Using the electrical schematic and electrical
wire harness drawings will also help in problem diagnosis.
•
The InfoCenter will display fault code numbers as an indication that the
machine electrical system has experienced an unusual change that might be
very minor resulting in no change of the machine operation or more severe
which could prevent machine use. Use the fault codes in conjunction with
noting what machine operations have changed, when did the change occur,
and whether the problem occurs all the time or is intermittent to help identify
the source of a machine problem.
•
The InfoCenter faults screen can be used to list all machine electrical faults
that have occurred since the faults were last cleared from the InfoCenter. If
a fault that is listed on the InfoCenter faults screen occurred at some point
in the distant past and has not reoccurred, that fault is likely not causing a
current machine problem. Recurring faults may indicate a problem with a
particular circuit or component.
•
When machine electrical issues occur and fault codes have been displayed
on the InfoCenter display, consider contacting your Toro Distributor for
additional assistance.
