2. When toggling "output" a LED should display
(Fig. 8d) any of the following problems diagnosed by the
TurfDefender:
Valve open circuit (LED blinking): Check / re-
place TurfDefender electric solenoid valve or wires.
Valve short circuit (LED blinking): Check / re-
place TurfDefender electric solenoid valve or wires.
Self diagnostic LED Blinking: Internal circuit fail-
ure in TurfDefender. Consult your Authorized Toro
Distributor for assistance.
Data Line LED Blinking: Problem with commu-
nications between machine and leak detector; or
problem with wires. Consult your Authorized Toro
Distributor for assistance.
Note: If machine must be operable with leak detector
disabled, unplug leak detector 4–pin connector from
4–pin connector of main harness. Do not unplug leak
detector alarm.
If false alarms are observed:
1. Oil level may be low causing air to be drawn out of
system. Check oil level.
2. Extremely hard left turns can cause oil to slosh to
the right, exposing suction line and purging air out of
system. Normal maneuvering should not cause this
condition.

3. Air leak in system. Check to make sure cap is se-
curely on tank. Contact your local authorized Toro Dis-
tributor for further assistance with air leak problem.
4. To check for a system problem, install hand held
Diagnostic ACE, toggle input/output and check for any
problems previously discussed.
Note: The system will reset itself whenever the ignition
key is turned to "OFF" position. The hand held Diagnos-
tic ACE must be connected and observed during a false
alarm. Once the ignition key is turned to "OFF" position,
the TurfDefender will reset itself.
5. Your Authorized Toro Distributor has equipment to
analyze system problems.
IMPORTANT: The Diagnostic ACE displays 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 them from the machine and reconnect
loopback connectors to harness connectors. Ma-
chine will not operate without loopback connectors
installed on harnesss. Store Diagnostic ACE in dry,
secure location in shop, not on machine.
