Verifying the Output Function
1.
Park the machine on a level surface, lower the
attachment, shut off the engine, and engage the
parking brake.
2.
Raise the seat.
3.
Locate wire harness and connectors near the
controller.
4.
Carefully unplug the loopback connector from
the harness connector.
5.
Connect the Diagnostic ACE connector to the
appropriate harness connector. If the machine
comes with a front attachment, it will have 2
controllers.
Note:
Ensure that the correct overlay decal is
positioned on the Diagnostic ACE.
6.
Turn the key switch to the O
not start the engine.
Note:
The red text on the overlay decal refers
to input switches and the green text refers to
outputs.
7.
The "inputs displayed" LED, on the lower
right column of the Diagnostic ACE, should
be illuminated. If the "outputs displayed"
LED is illuminated, press the toggle button
on the Diagnostic ACE to change it to "inputs
displayed."
Note:
You may need to toggle between "inputs
displayed" and "outputs displayed" several times
to do the following step. To toggle back and
forth, press the toggle button once. Do this as
often as necessary; do not hold the button.
8.
Sit on the seat and attempt to operate the
desired function of the machine. The appropriate
output LEDs should illuminate to indicate that
the ECM is turning on that function.
Note:
If the correct output LEDs do not illuminate,
verify that the required input switches are in the
necessary positions to allow that function to occur.
Verify the correct switch function.
If the output LEDs are on as specified but the
machine does not function properly, this indicates a
non-electrical problem; repair as needed.
Note:
If each output switch is in the correct position
and functioning correctly but the output LEDs are
not correctly illuminated, this indicates an ECM
problem. If this occurs, contact your Toro Distributor
for assistance.
Important:
Do not leave the Diagnostic ACE
display connected to the machine. It is not
designed to withstand the environment of the
position, but do

everyday use of the machine. After using the
Diagnostic ACE, disconnect it from the machine
and connect the loop-back connector to the
wire-harness connector. The machine cannot
operate without the loopback connector installed
on the wire harness. Store the Diagnostic ACE
in dry, secure location in the shop, not on the
machine.
