I have brought an airbag control unit of a Fiat 500 remained without the battery once replaced ? appeared the error "low voltage" wanting to avoid a programming problem I tried to put a file I think is good.
The unit in question ? a Siemens VDO 5WK43908 51782985, I am attaching the original file and the one I changed, if someone can check the file or has any advice ? well I agree..

Thanksfiat 500.rar
