Retrieving Fault Codes
All machinefault codes areretained in theTEC control-
ler memory. The three (3) most recent fault codes that
have occurred w ithin 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 switch sequence:
1. Operator seat should be UNOCCUPIED, traction
pedalinneutral,parkingbrakereleasedandPTOswitch
in the OFF position.
2. Place mow speed limiter in the TRANSPORT posi-
tion.
3. Move and hold joystick in the RAISE position.
4. Turn ignition switch to the RUN position.
5. Monitor the diagnostic light for fault code(s).
NOTE: Once thediagnostic lightbegins todisplay fault
codes, the joystick can be released.

If there are no faults that have occurred within the last
forty (40) hours of operation, the diagnostic light will

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.
Fault Code (Lamp Flashes)
Fault Description
1--1 High engine temp warning occurred (PTO was shutdown by controller)
1--2 High engine temp shutdown occurred (engine was shutdown by controller)
1--3 Low engine oil pressure occurred
1--4 Engine alternator fault occurred
Clearing Fault Codes
After fault codes have been retrieved, clearing of those
faults can be completed using the following switch se-
quence:
1. Place machine switches in fault retrieval (see
above). The diagnostic light should be displaying the
fault codes.
2. Operator seat should remain UNOCCUPIED.
3. Move mow speed limiter to the MOW position.
4. Move joystick to the RAISE position.
5. Monitor the diagnostic light for continuous flashing
indicatingthatallfaultshavebeenclearedfromthecon-
troller memory.
