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 distributor
can use to identify the problem.
Note:
You cannot start the engine in 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 one fault, the tens place
of the next fault will begin after a pause after the
ones place of the first fault.
