Kubota Gasoline Engine Electronic Control Module (ECM)
The Kubota gasoline engine that powers your Multi Pro
5800−G uses an electronic control unit (ECM) for engine
management. All wire harness electrical connectors
should be plugged into the ECM before the machine
ignition switch is moved from the OFF position to either
the ON or START position.
The engine electrical components (e.g. ECM, O2
sensor, throttle control, power relay, ETV relay) are
identified and matched in the engine ECM program. If
engine electrical components are replaced on the en-
gine, the Kubota electronic tool must be used to update
the ECM program which will ensure correct engine oper-
ation.
If the engine ECM identifies that an engine problem ex-
ists, an engine fault may appear on the InfoCenter Dis-
play. In addition, the engine speed may be reduced or
the engine might stop. The Kubota Gasoline Service
Tool (KGST) and software, and the Kubota Diagnosis
Manual − ECM System should be used to provide as-
sistance in identifying the cause of the problem and any
repairs that are necessary. Contact your Toro distributor
for assistance in Kubota engine troubleshooting.
IMPORTANT: Do not plug or unplug the engine
ECM for a period of thirty (30) seconds after the ma-
chine key switch is turned OFF. The ECM may re-
main energized even though the ignition switch is
OFF.
If the engine ECM is to be disconnected for any reason,
make sure that the ignition switch is in the OFF position
with the key removed before disconnecting the engine
ECM. Also, to prevent possible ECM damage when
welding on the machine, disconnect and remove the en-
gine ECM from the machine before welding.
