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.
2. Place functional control lever in the TRANSPORT
position.
3. Make sure that backlap valve on mow control man-
ifold is in the MOW position.
4. Move and hold joystick in the RAISE position.
5. Turn ignition switch to the RUN position.
6. Monitor the diagnostic light for fault code(s).
NOTE: Once thediagnostic lightbegins todisplay fault
codes, the joystick can be released.
Fault codes displayed by the diagnostic light consist of
atwodigitnumber.Faultcodesarelistedinthechartbe-
low. There will be a one (1) second pause between the
first and second digit of a code. Up to three (3) fault
codesretainedincontrollermemorywillbedisplayedby

the oldest fault. If there are multiple faults in controller
memory,therewillbeathree(3)secondpausebetween

(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 fault re-
trieval switch sequence.

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.
