Engine Electronic Control Unit (ECU) (continued)
Yanmar Diesel Engine: General Information
If the engine ECU is to be disconnected for any reason, make sure that the
key switch is in the OFF position with the key removed before disconnecting
the engine ECU. Also, to prevent possible ECU damage when welding on the
machine, disconnect the engine ECU from the machine before welding.
The engine ECU is mounted to the machine using four (4) rubber isolator
mounts. The mounts isolate the ECU from the machine electrically, and reduce
machine vibration to the ECU. Make sure the ECU isolator mounts remain soft
and unbroken. Replace isolator mounts as necessary.
