Troubleshooting
Engine Management System
Kubota provides software that enables you to use a laptop to
interface with the engine controller like an “automotive scan tool”.
It is called the Kubota Gasoline Service Tool (KGST). Although it
mentions “gasoline” (petrol) in the name, it is also for use with the
propane fueled engine. The KGST is essential for troubleshooting
engine management system issues.
The KGST software and Kubota KGST User Guide are available
through EZparts.
You will need:
• Laptop with USB port
• KGST Software (Found in EZParts)
• ECOM Cable for connecting the laptop to the machine. (See Special Tools section.)
– ECOM Cable driver (Found in EZParts)
• ECOM Cable adapter to go between the ECOM cable in the machine diagnostic connector. (See Special
Tools section.)
See the Kubota KGST User Guide for further instructions. The software requires the use of a password for
the WGG972GL-E4 (LEV) engine. The password is:
