A. The “inputs displayed
” LED, on lower right
column of the Diagnostic ACE, should be
illuminated.If “outputs displayed
”LEDis illuminated,
pressthetogglebuttonon DiagnosticACEtochange
to “inputs displayed
”LED.Do not hold button.
B. The Diagnostic ACE will illuminate the LED
associated with each of the inputs when that input
switch is closed. Individually, c hange each of the
switches from open to closed (i.e., sit on seat, en-
gage traction pedal, etc.), and note that the appropri-
ateLED on DiagnosticACE willblink on and offwhen
corresponding switch is closed. Repeat on each
switch that is possible to be changed by hand.
C. 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 wir-
ing.
D. If each input switch is in the correct position and
functioning correctly, but the input LED’s are notcor-
rectly illuminated, this indicates an controller prob-
lem. If this occurs, contact your Toro Distributor for
assistance.
4. Check Output Functions
A. The “outputs displayed
” LED, on lower right
column of Diagnostic ACE, should be illuminated. If
“inputs displayed
” LED is illuminated, press the
toggle button on the Diagnostic ACE to change the
LED to “outputs displayed
”.
Note: It may be necessary to toggle between “
in-
puts displayed
” and “outputs displayed” several
times to do the following step. To toggle back and
forth, press togglebutton once.This maybe doneas
often as required. Do not hold button.
B. Sit on seat and attempt to operate the desired
function of the machine. The appropriate output
LED’sshould illuminateto indicate that thecontroller
is turning on that function.
Note: If any output LED is blinking, this indicates
an electrical problem with that OUTPUT.Repair and/
or replace defective electrical parts immediately. To
reset a blinking LED,turn the key switch “OFF”,then
back “ON” and retest. Memory must also be cleared
(see Clearing the Fault Memoryin this section ofthis
manual).
C. If no output LED’s are blinking, but the correct
output LED’s d o not illuminate, verify that the re-
quired input switches are in the necessary positions
to allow that function to occur. Verify correct switch
function.
D. If the output LED’s are on as specified, but the
machine does not function properly, this indicates a
non-electrical problem. Repair as necessary.
Note: Due to electrical system constraints, the output
LED’sfor“START”,“PREHEAT”and“ETR/ALT”maynot
blink even though an electrical problem may exist for
those functions. If the machine problem appears to be
with one of these functions, be certain to check the
electrical circuit with a volt/ohm meter to verify that no
electrical problem exists to these functions.
E. If each output switch is in the correct position and
functioning correctly, but the output LED’s are not
correctly illuminated, this indicates an controller
problem. If this occurs, contact your 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 machine’s ev-
ery day use. When done using Diagnostic ACE, dis-
connect it from the machine and reconnect
loop-back connector to harness connector. Ma-
chine will not operate without loop-back connector
installed on harness. Store Diagnostic ACE in dry,
secure location in shop, not on machine.
Fault Memory and Retrieval
If the Controller senses a fault on one of the output
so-
lenoids
, it will flash the machines diagnostic Lamp (red
diagnostic lamp on steering tower or green diagnostic
lamp under console) and store the fault into the control-
ler memory. The fault can then be retrieved and viewed
withtheDiagnosticACEhandheld tooloralap top/PCat
anytime. The controller will store one (1) fault at a time
andwill not store another differentfault until the firstfault
is cleared.
Retrieving Stored Faults
1. Rotate ignition key to Off position.
2. Connect the Hand held Diagnostic Tool to the de-
sired Controller Loopback Connector (use the proper
overlay).
3. Move the Joystick to the Raise position and hold.
4. Rotate ignition key to On position, and continue to
hold the Joystickin Raise position until the top left Diag-
nostic Tool light comes on (approx. 2 seconds).
5. Release the Joystick to the center position.
6. Hand held Tool will now playback the fault retained
in the Controller memory.
