Yanmar Engine Electronic Control Unit (ECU)
The Yanmar engine that powers the Groundsmaster
4100--D and 4110--D uses an electronic control unit
(ECU) for engine management and also to communi-
cate with the TEC controllers and the InfoCenter Display
on the machine. All engine ECU electrical connectors
should be plugged into the controller before the machine
ignition switch is moved from the OFF position to either
the RUN or START position. If the engine ECU is to be
disconnected for any reason, make sure that the ignition
switch is in the OFF position with the key removed for a
minimum of thirty (30) seconds before disconnecting the
engine ECU. See Chapter 3 -- Yanmar Diesel Engine for
additional engine ECU information.
