4. Use the screen select button to navigate to the TDM display/controller
Diagnostics> Input/Output>Output screen for the desired machine operation.
Engine has been selected for this example.
When the correct inputs are received by the controller, the output identified
on the Output screen should show as ON (check-mark in box). If the inputs
are functioning properly and in the correct position for the operation to occur,
and the output remains OFF (empty box), the controller software may require
reloading or replacement. Contact your Authorized Toro Distributor for
assistance with controller reprogramming or replacement.
As an example; if the traction pedal is in neutral and parking brake is
engaged or an operator is in the seat, the OK Run output display should
come ON (check-mark in box). With the OK Run output display ON, the
engine is allowed to crank when the key switch is set to the S
TART
position
(refer to Figure 7 ).

Note: If the Oil Pressure input does not display ON within 10 seconds after
the engine has started, or if the Coolant Temp input voltage goes below
0.153V for 10 seconds (model 31900, 31901, 31907 and 31909 only), the OK
Run output display should go OFF (empty box) and the engine should stop.
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
Testing the Electrical
Components (page 6–9) .
