The Diagnostics − Input/Output screens of the InfoCenter display can be very
helpful when troubleshooting machine operation issues (see
SCREENS (page 6–22)). Some of the electrical components and the circuit
wiring involved in various machine operations can be evaluated using the Input/
Output screens prior to testing each component individually. The Input/Output
screens show the current state of the inputs, qualifiers and the outputs required
to allow the operation to proceed
It may be necessary to start and run the engine, raise and lower
the cutting units, or otherwise operate the machine during the
troubleshooting process. Make sure the machine is in a well
ventilated area and keep away from cutting units and moving parts
while troubleshooting to prevent personal injury.
If a machine operation is malfunctioning, the following procedure can help
identify the component or circuit wiring causing the malfunction.
1. Park machine on a level surface, lower cutting decks if possible and stop
engine.
2. Set the key switch to the RUN position and navigate to the InfoCenter
Diagnostic − Input/Output Screen for the desired machine function. For this
example, the PTO operation has been selected.
3. Manually operate the input or qualifier component. The component state on
the InfoCenter display should alternate ON and OFF as the component is
switched open and closed. If ON and OFF do not alternate during component
operation, the component or its circuit wiring is faulty and should be tested
(see Testing (page
When the correct inputs and qualifiers are received by the controllers, the
outputs identified on the Input/Output screen should show as ON. If the inputs
and qualifiers are properly positioned and the output remains OFF, a problem
with controller power (circuit wiring or fuse) may exist, or the Toro Electronic
Controller (TEC) or TEC software may require reloading or replacement. Contact
your Authorized Toro Distributor for assistance.
