I have to say that I don't speak Spanish but I think that you have a problem with the power steering on your Kawasaki mule?
Is the power steering fault light staying on ? after the engine is started?
if so have you replaced any parts?
Ok a new power steering ECU will not just 'plug and play' as they need to be registered with the main ECU
sorry to say that you're going to have to get the dealer involved as they carry the correct equipment to get all the modules communicating with each other
if there's another way I'm unaware of it but I'll opt out and open this back to others
