Komatsu excavator PC220LC-6LE SN: A83897 the problem is that it will run just fine for sometimes for 5-15 or longer and then the motor goes to idle and missing, there is no black smoke it will just run rough and no response to idle selector, a E02 code will come up on the display and if you use too much hydro functions it will kill the motor. Nothing changes if you try to keep running it. if you shut it down and restart the machine it will still run rough, if you shut off the machine for 3-5min it will start up and run normally and the E02 code is gone. might run for a little while normally and then the motor goes back to idle running rough and E02 code comes back. Any ideas? Thanks
Advise to follow link provided. John C has put together a series of very helpful videos. He will show you how to extract the error codes. You must do this while the code is active. Get the alphanumeric code and we can help you further. Good luck
The machine is in Alaska and I will be up there at the end of the month. I will have my brother run through this as soon as he can and I will make another post of what we find.
we cleared all the codes and what we have is E203 that we know about, we currently are using the swing override. E215 not sure what this is E233 when E02 flashes when engine runs crappy.
