Hello, I have a Fiat Barchetta MY97. I can connect successfully to the Hitachi ECU, but not to the Airbag ECU (the yellow 3 pin connector). The Airbag ist a TRW 46443798. I am using a USB->K-Line and then a 3-pin connector, all unmodified. Am I doing something wrong or is this airbag control unit no...
