Komatsu ECU modules: sourcing and compatibility

Differences between new, used, and remanufactured options for the electronic control module. An ECU swap is not just a part swap; programming to the machine serial number and sensor calibration is half the job.

When buying a used ECU, make sure the hardware revision code matches exactly — even the same machine model can use a different software base across production years. Modules from our stock are bench-tested before dispatch.
