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 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 necessary.
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 authorized
Toro distributor for assistance.
Important:
The Diagnostic ACE display must not be left connected to the machine. It is not
designed to withstand the environment of the everyday use of the machine. When you are finished
using the Diagnostic ACE, disconnect it from the machine and connect the loop-back connector to
the harness connector. The machine does not operate without the loop-back connector installed
on the harness. Store the Diagnostic ACE in a dry, secure location in the shop, not on the machine.
