Last week I had to jump start my l3901 after a light had been left on. It started right up with the jump (was jumped per manuel instructions), but now I have a P0606 code. The battery and alternator tested good. I even disconnected the battery twice and let it sit overnight but the code is still there when I restart it. All the wiring looks good and the tractor is kept in the garage. Is this code something the dealer is going to have to reset? Thanks

Thanks for the response. The tractor starts and runs normally other than the code. Is there going to be any harm or issue if I keep using it until after Christmas?

Did you reset the code and it came back?

The link shows how to clear code from the panel. it doesn't tell you how to clear it from the ecu. panel and ecu use different memories and they both will store dtc's. you cannot clear the ecu's memory, only dealer can. 606 is defined by kubota as a ecu/can communication error. that can come from a million different things. clear it from panel, keep running it and don't run the battery dead or disconnect it, if the code comes back you could have a wiring or ecu problem.

Download a WSM for ur 3901. It has all that code info and reset info along with any other settings and instructions u will probably ever need to work on your tractor..

Is there a way to clear it if it is the “A” code? My MX4800 wouldn’t start due to a cold / weak battery this morning but started fine after I put my jump battery on it but now I have 0606 code stuck on the panel.
