closed (i.e., sit on seat, engage the traction pedal,
etc.), and note that the appropriate LED on
Diagnostic ACE will blink on and off when cor-
responding switch is closed. Repeat on each
switch that is possible to be changed by hand.
7. If switch is closed and appropriate LED does not
turn on, check all wiring and connections to
switch and/or check switches with an ohm meter.
Replace any defective switches and repair any
defective wiring.
The Diagnostic ACE also has the ability to detect
which output solenoids or relays are turned on. This is
a quick way to determine if a machine malfunction is
electrical or hydraulic.
To verify output function:
1. Park the machine on a level surface, lower the
cutting units, stop the engine and engage the
parking brake.
2. Open the control panel cover. Locate the wire
harness and connectors #1 and #2 (Connectors
will have visible labels attached noting #1 and
#2). Set the height-of-cut selector knob to posi-
tion "A".
3. Connect the Diagnostic ACE display connectors
to the correct harness connectors. Overlay decal
#1 must be used on connection #1 and overlay
decal #2 must be used on connection #2.
4. Turn the key switch to the ON position, but do
not start the machine.
Note: The red text on the overlay decal refers to
input switches and the green text refers to out-
puts.
5. The "outputs displayed" LED, on lower right col-
umn of the Diagnostic ACE, should be illuminat-
ed. If the "inputs displayed' LED is illuminated,
press the toggle button on Diagnostic ACE to
change LED to "outputs displayed".
Note: It may be necessary to toggle between
"inputs displayed" and "outputs displayed" sever-
al times to do the following step. To toggle back
and forth, press the toggle button once. This may
be done as often as required. DO NOT HOLD
THE BUTTON.

6. Sit on the seat and attempt to operate the desired
function of the machine. The appropriate output
LEDs should illuminate to indicate that the ECU is
turning on that function. (Refer to the list below to
be certain of the specified output LEDs.
Note: If any output LED is blinking, this indicates an
electrical problem with that OUTPUT. Repair or
replace defective electrical parts immediately. To reset
a blinking LED, turn the key switch to "OFF", then
back to "ON".
If no output LEDs are blinking, but the correct output
LEDs do not illuminate, verify that the required input
switches are in the correct positions for the function to
occur.
If the output LEDs are on as specified, but the machine
does not function properly, this indicates a non-electri-
cal problem. Repair as necessary.
Note: Due to electrical system constraints, the output
LEDs for "START", "PREHEAT" and "ETR/ALT"
may not blink even though an electrical problem may
exist for those functions. If the machine problem
appears to be with one of these functions, check the
electrical circuit with a volt/ohm meter to verify that no
electrical problem exists to these functions.
If each input switch is in the correct position and func-
tioning correctly, but the output LEDs are not correctly
illuminated, this indicates an ECU problem. If this
occurs, contact your Toro Distributor for assistance.
FAULT MEMORY AND RETRIEVAL
If the controller senses a fault on one of the output
solenoids, it will flash the machine's diagnostic lamp
(reel control lamp or green diagnostic lamp under the
console) and store the fault into the controller's (ECU)
memory. The fault can then be retrieved and viewed
with the Diagnostic ACE hand-held tool or a laptop PC
at any time. The controller will store one (1) fault at a
time and will not store another different fault until the
first fault is cleared.

1. Turn the ignition key to the Off position.
