Please help how do I do to factory settings ECU

thenks.

FES software can not help you with that! With FES you can read and delete errors form different ECUs (engine, abs, airbag...) and read some parameters and that is pretty much it...
You need some kind of flashing tool and flashing software to do that...
I would advise you not to do reset of your ECU because in general you do not need it or if you want to do it just find someone who is professional it that field and the can help you with resetting ECU...
