Hello. I have recently bought a 2002 fiat stilo 3dr 1.2 with the airbag light on. I connected the car with diagnostic and it said that : " Control Unit Fault - Present" . What is this fault? How can i deal with this problem?? I have cleaned the cables under the seats and the ocs sensor is ok (replaced 2 days ago with an emulator). Thanks in advance :)
 
I use fiat multi ecu scan. And it said :"control unit fault -present". I guess it means that the airbag control unit has problem , but how can i fix it?
 
did it give you a 2 digit code for example A0 or 8F.

are you positive you have the right Airbag ECU selected theres loads of different options and easy to get wrong, you can 'auto detect' using the 'Scan' option which iirc is F11. also check that you are using the correct patch cable (red adapter) and K-line/Vagcom interface.

(im not saying that you havent got all these things right but sometimes its easy to get confused/select the wrong option)
 
The diagnostic scan showed exactly: " 01- Control unit fault-unknown/internal error-Present-75 " Of course i pressed "scan" to find the right option (2 front airbags 2 side airbags 2 curtain airbags 2 pretensioners). And just to be sure my brother (who knows really well how to use fiat multiecu scan ) did the scan, so i am 100% sure that the scan was done the right way...:) But what i dont know is what to do to fix the problem, to be sure the airbags will work, because i dont wanna change the airbag control unit (too expensive and here in Greece the money are not easy to find).
