Diagnostics System
Diagnosing the Service
Indicator Light
The service indicator light illuminates in the event of
a fault in the machine. When this light is on, you can
access the computer codes to diagnose the problem
by entering diagnostic mode. In diagnostic mode,
the service indicator light flashes a number of times,
giving you the error code that you or your authorized
Toro distributor can use to identify the problem.
Note:
You cannot start the engine in diagnostic mode.
Entering Diagnostic Mode
1.
Stop the machine, set the parking brake, and
turn the ignition key to the O
FF
position.
2.
Move the functional-control lever to the
T
RANSPORT
position.

Ensure that the backlap lever is set to the
F
ORWARD
(F) position.
4.
Get off the seat.
5.
Hold the raise/lower mow control in the R
AISED
position.
6.
Turn the ignition switch to the R
UN
position.
7.
Count the codes as they begin to flash (you may
release the raise/lower mow control once they
begin flashing).
When finished, turn the key to the O
FF
position to exit
diagnostic mode.
Determining the Error Code
The system will display the last 3 faults that occurred
in the last 40 hours. It displays the faults through a
series of blinking lights, as follows:
•
If there are no faults, the light will blink steadily at
a medium rate without pauses (1 Hz).
•
If there is a fault, it will first blink the tens place,
followed by a pause, followed by the ones place.
For the following examples, a # represents a blink.
Examples:
– If the code is 15, the blink pattern will be
#_#####
– If the code is 42, the blink pattern will be
####_##
– If the code is 123, the blink pattern will be
############_###
•
If there are more than 1 fault, the tens place of the
next fault will begin after a pause after the ones
place of the first fault.
Note:
The system stores only the 3 most recent
fault codes.
For a list of error codes, refer to your authorized Toro
distributor or the
Service Manual
