Retrieving Fault Codes; Clearing Fault Codes - Toro GroundsmasterR 4300-D Service Manual

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 switch sequence:
1. Operator seat should be UNOCCUPIED, traction
pedal in neutral, parking brake released and PTO switch
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 the diagnostic light begins to display fault
codes, the joystick can be released.

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.
Groundsmaster 4300--D
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 below. There will be a one (1) sec-
ond 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) sec-
ond pause between codes. The fault codes will continu-
ally 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 switch se-
quence.
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.
High engine temp warning occurred (PTO was shutdown by controller)
High engine temp shutdown occurred (engine was shutdown by controller)
Low engine oil pressure occurred
Engine alternator fault occurred
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
indicating that all faults have been cleared from the con-
troller memory.
