On the FIAT Bravo 19 TD I light the Airbag is turned on. With a diagnosis gives me errors U1726, U1601 and B102C. Should be due to the fact that the unit Body does not find the Airbag control unit. I have checked the connections and they seem fine, I'm worried that the Airbag control unit is faulty. The problem may be on the same chip, the error in the case of a crash?
If I remove and rewrite the files, it is possible to solve?
Thanks to anyone willing to provide other information.
