To verify interlock switch function:
1. Park machine on a level surface, lower the cutting
units, stop the engine and engage the parking brake.
2. Open control panel cover. Locate wire harness and
connector. Carefully unplug loopback connector from
harness connector.
3. Connect the Diagnostic ACE display connector to the
harness connector. Make sure correct overlay decal is
positioned on Diagnostic ACE display.

5. The "inputs displayed" LED, on lower right column of
the Diagnostic ACE, should be illuminated. If "outputs
displayed" LED is illuminated, press and release the
Electrical System
toggle button, on Diagnostic ACE, to change LED to "in-
puts displayed". Do not hold button down.
6. The Diagnostic ACE will illuminate the LED
associated with each of the inputs when that input switch
is closed. Individually, change each of the switches from
open to closed (i.e., sit on seat, engage traction pedal,
etc.), and note that the appropriate LED on Diagnostic
ACE will blink on and off when corresponding 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 defec-
tive 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 machine on a level surface, lower the cutting
1
units, stop the engine and engage the parking brake.
2. Open control panel cover. Locate wire harness and
connectors near controller. Carefully unplug loopback
connector from harness connector. Set HOC selector
knob to position "A".
3. Connect the Diagnostic ACE connector to the har-
ness connector. Make sure correct overlay decal is posi-
tioned 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 dis-
played" 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. The appropriate output LED's
should illuminate to indicate that the ECU is turning on
that function. (Refer to the list on page 21 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
