OPERATING INSTRUCTIONS
3.
Connect the Diagnostic ACE connector to the
harness connector. Make sure correct overlay decal is
positioned on Diagnostic ACE.
4.
Turn the key switch to the ON position, but do not
start machine.
Note:
The red text on the overlay decal refers to input
switches and the green text refers to outputs.
5.
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 Diagnostic ACE, to change LED to outputs
displayed".
Note:
It may be necessary to toggle between inputs
displayed" and outputs displayed" several times to do
the following step. To toggle back and forth, press
toggle button once. This may be done as often as
required. DO NOT HOLD BUTTON.
6.
Sit on the seat and attempt to operate the desired
function of the machine. (If you need help verifying the
correct input settings for each function, refer to the
Logic Chart on page 22) The appropriate output LED's
should illuminate to indicate that the ECU is turning on
that function. (Refer to the logic chart to be certain of
the specified output LED's).
Note:
If any output LED is blinking, this indicates an
electrical problem with that OUTPUT. Repair / replace
defective electrical parts immediately. To reset a
blinking LED, turn the key switch OFF", then back
ON".
If no output LED's are blinking, but the correct output
LED's do not illuminate, verify that all the input switches
work by following the instructions on how to verify
interlock switches. Verify correct switch function.
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's for START", MONITOR" 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, be certain to check the
electrical circuit with a volt / ohm meter to verify that no
electrical problem exists to these functions.
If electronic controller experiences an output failure for
either the cruise control or one of the cutting units, the
controller will disable the machine function.
Indications that this is the cause of the problem
include:
A. Flashing green diagnostic light.
B. Diagnostic ACE will illuminate the output fail"
LED.
C. Diagnostic ACE will flash which output failed.
D. Machine will not respond to ignition key inputs.
The above indicates an ECU problem, contact your
local Authorized TORO Distributor for assistance.
If each output switch is in the correct position and
functioning correctly, but the output LED's are not
correctly illuminated, this indicates an ECU problem. If
this occurs, contact your Toro Distributor for
assistance.
IMPORTANT: The Diagnostic ACE display should
not be left connected to the machine. It is not
designed to withstand the environment of the
machine's every day use. When done using
Diagnostic ACE, disconnect it from the machine
and reconnect loopback connector to harness
connector. Machine will not operate without
loopback connector installed on harness. Store
Diagnostic ACE in dry, secure location in shop, not
on machine.
