Note: See Leak Detector Troubleshooting Guide in
this section of this manual for additional information.
1. Park machine on a level surface and engage the
parking brake.
2. Open control panel cover.
Locate leak detector harness loopback connector
with hydraulic symbol tag. Carefully unplug loopback
connector from harness connector.
3. Connect the Diagnostic ACE display connector to
the correct harness loopback connector. Install TurfDe-
fender overlay decal (supplied with leak detector kit) on-
to Diagnostic ACE (Fig. 13).
4. The ignition key switch must be turned to the "ON"
position.
Note: Red text on the overlay decal refers to inputs
and green text refers to outputs.
5. The red "Inputs displayed" LED (Light Emitting
Diode), on lower right column of the Diagnostic ACE,
should be illuminated. If green "Outputs displayed" LED
is illuminated, press and release the toggle button, on
Diagnostic ACE, to change LED to "Inputs displayed".
Do not hold button down (Fig. 13).
If TurfDefender is functioning normally:
1. When the "Inputs displayed" LED is lit, the actual
Float position (1 or 2 LED's on left side) and "Oil level
OK" LED (right side) -- should be displayed (Fig. 14).
2. Press toggle button until green "Outputs displayed"
LED is lit. "Valve ON", "data line" and "self diagnos-
tic"LED's should be lit steadily. "Alarm ON" LED may be
displayed temporarily (about 5 seconds) (Fig. 15).
Note: If "data line" or "self diagnostic" LED's are
blinking, there is a problem in the system.
If No beeps are heard:
1. Check alarm wires to make sure they are not discon-
nected, broken or "+" and "--" reversed.
2. Make sure TurfDefender 4--pin connector is plugged
in.
3. Make sure TurfDefender 5 amp fuse (fuse block "B",
slot #3) is not blown.
4. Toggle "outputs displayed" on Diagnostic ACE dis-
play (Fig. 15).
S Alarm open circuit (LED blinking): Check/replace
TurfDefender alarm or wires.

1. Electric solenoid valve
If 4 beeps are heard:
The most common cause for a 4 beep signal is from an
improper oil level reading. Make sure machine is on a
level surface when checking oil level. Since oil level will
vary with temperature, it is best to check when cool.
1. When toggling "input", a LED should display
(Fig. 14) any of the following problems diagnosed by the
TurfDefender:
S Oil level low: Position machine on a level surface
and fill to proper level.
S Oil level high: Position machine on a level surface
and remove excess oil until proper level is attained.
S Air leak in system: Assure tank cap is tight or check
for leak in tank.
Note: Only large air leaks can be detected by hand
held Diagnostic ACE. A leakdown test is required to
identify small air leaks. Consult your Authorized Toro
Distributor for assistance.
2. When toggling "output" a LED should display
(Fig. 15) any of the following problems diagnosed by the
TurfDefender:
S Valve open circuit (LED blinking): Check/replace
TurfDefender electric solenoid valve or wires
(Fig. 11).
S Valve short circuit (LED blinking): Check/replace
TurfDefender electric solenoid valve or wires
(Fig. 11).
S Self diagnostic LED Blinking: Internal circuit failure
in TurfDefender. Consult your Authorized Toro Dis-
tributor for assistance.
S Data Line LED Blinking: Problem with communica-
tions between machine and leak detector; or prob-
lem with wires. Consult your Authorized Toro
Distributor for assistance.
S Drip Drop LED Blinking: A slow oil leak (level drop)
may be detected.
