Retrieving Fault Codes
All machine fault codes are retained in the TEC control-
ler memory. The three (3) most recent fault codes that
have occurred within the last forty (40) hours of opera-
tion can be retrieved using the diagnostic light. To re-
trieve these fault codes from the controller memory,
perform the following steps:
1. Make sure that ignition switch is OFF.
2. Raise and support operator seat.
3. Locate diagnostic tether cap that connects the two
(2) diagnostic shunt wires located under the operator
seat (Fig. 10).
4. Remove diagnostic tether cap from diagnostic shunt
wires and connect the two (2) shunt wires together (Fig.
11).
5. Turn ignition switch to the RUN position.
6. Monitor the diagnostic light for fault code(s).
Fault codes displayed by the diagnostic light are two dig-
it numbers with no digit higher than five (5). Fault codes
are listed in the chart on the following page. There will
be a one (1) second pause between the first and second
digit of a code. Up to three (3) fault codes retained in
controller memory will be displayed by the diagnostic
light in order from the most recent fault to the oldest fault.
If there are multiple faults in controller memory, there will
be a three (3) second pause between codes. The fault
codes will continually repeat after a five (5) second
pause until the ignition key is turned off.
If there are no faults that have occurred within the last
forty (40) hours of operation, the diagnostic light will
flash continuously after performing the above steps.
If a fault code is not retrieved from the controller memory
within forty (40) hours of machine operating time, the
fault cannot be retrieved from controller memory using
this procedure. If necessary, contact your Toro distribu-
tor to retrieve older fault codes.
Clearing Fault Codes
After fault codes have been retrieved, clearing of those
faults can be completed using the following switch se-
quence:
1. Make sure that the seat is not occupied and the park-
ing brake is not applied. Also, put the steering selector
switch in the 2 wheel steering position.

2. Place machine in fault retrieval mode (see above).
The diagnostic light should be displaying the fault
codes.
3. Press the steering selector switch to the 4 wheel
steering position.
4. Monitor the diagnostic light for continuous flashing
indicating that faults have been cleared.
5. After fault codes have been cleared, turn ignition
switch to the OFF position. Unplug diagnostic shunt
wires and connect diagnostic tether cap to wires.
6. Lower and secure operator seat.
