Using the InfoCenter Display for Troubleshooting
The InfoCenter Splash Screen and Main Information Screen can be used to
check the operation of various components. The neutral, parking brake, and seat
icons represent the switch activity and can be used to verify the switch and its
circuit wiring integrity. The battery icon can be used to check battery voltage and
circuit wiring integrity.
The Diagnostics − Input and 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 screens prior to
testing the component individually. The screens can show the current state of
the inputs and the outputs required to allow a machine operation to proceed, or
report electrical performance (voltage or currant) of a specific component. Refer
to
InfoCenter (page 5–10)
for a guide to the various InfoCenter screens.
CAUTION
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 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 the cutting units if possible and stop
engine.
2. Set the key switch to the R
UN
position and navigate to the InfoCenter
Diagnostics > Input
or
Output
Screen for the desired machine function.
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 operated. 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
Testing the Electrical Components (page 5–23)
and
(page A–1)
.
Note:
– – – means no signal from the input is available on the CAN bus and
the input or the CAN bus 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 is reported.
If the inputs are properly positioned and the output remains OFF or the control
amperage is not as expected, a problem with controller output 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
Components (page 5–23)
and
Appendix A (page A–1)
