Hi,
After flashing the ECU on a 6195R John Deere tractor, L21, after a while some error codes apairs that claim regeneration.
I am pretty sure that the mod file was good, but I'm not sure that I respected the steps for this.

I read the ECU without resseting the DPF and clear the codes. After flashing the ECU the engine run for a while with the sensors plugged, till the error codes were set. Now the sensors are unppluged but the engine is still in derate condition.


My question is : Is that mandatory to reset the dpf and clear the codes and the ori file to be modified in that way, on John Deere L2x ecu's?
Mod file must be cleared of codes and 0 dpf values?

Thanks
