Using the InfoCenter Display for Troubleshooting
The Service − Input/Output screens of the InfoCenter display can be very helpful
when troubleshooting machine operation issues. Electrical components and their
circuit wiring can be evaluated quickly using the Input/Output screens prior to
testing the component individually. The Input/Output screens show the current
state of the inputs and the outputs required to allow a machine operation to
proceed.
CAUTION
It may be necessary to start and run the engine, raise and lower
the attachments, or otherwise operate the machine during the
troubleshooting process. Make sure the machine is in a well
ventilated area and keep away from attachments 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 attachments if possible and stop
engine.
2. Set the key switch to the RUN position and navigate to the InfoCenter Service
− Input/Output Screen for the desired machine function. Traction has been
selected for the following example.
3. Manually operate the input component. The component state on the
InfoCenter display should alternate ON and OFF or the signal voltage from
the component should change as the component is cycled. If ON and OFF do
not alternate or signal voltage does not change during component operation,
the component or its circuit wiring is faulty and should be tested; refer to
Electrical Component Testing (page 6–14)
and
Appendix A (page A–1)
.
Note:
– – – means no signal from the input is available and the input or its
circuit wiring should be tested.
When the correct inputs are received by the controllers, the outputs identified
on the Output screen should show as ON (or a control amperage in the case
of the traction pump control solenoids). If the inputs are properly positioned
and the output remains OFF, a problem with controller power (circuit wiring
or fuse) may exist, or the controller software may require reloading or
replacement. Contact your Authorized Toro Distributor for assistance.
A faulty output component will not be identified by the Output screen. The
Output screen reflects the actions of the controller, not the component(s)
involved in the operation. If all inputs and outputs are correct for the machine
operation selected, yet the operation does not function as it should, the
output component may be faulty. Test the specific output component and the
wiring from the controller to the component; refer to
and
Appendix A (page A–1)
.

positions. The TRANSMISSION FWD and REV inputs should alternate ON
and OFF based on the lever position. If not, the transmission lever switches
or their circuit wiring are faulty and should be tested.
