If the engine ECU identifies that an engine problem exists, the engine speed may
be reduced or the engine might stop running. The Kubota Diagnosis Manual and
Kubota Gasoline service tool should be used to provide assistance in identifying
the cause of the problem and the repairs that are necessary. Contact your Toro
distributor for assistance in Kubota gasoline engine troubleshooting.

If the engine ECU is to be disconnected for any reason, ensure that the key
switch is in the O
FF

before disconnecting the engine ECU. Also, to prevent possible ECU damage
when welding on the machine, disconnect and remove the engine ECU from
the machine before welding.
