I have a 2005 BMW m3 and the airbag light been on when I disconnected my seat. Needed to get it reset so I bought this Autel MaxiAP AP200 OBD2 scanner. As you can see from the picture, I was able to get it reset successfully from the application I had to download. You will have to download which car you have.
Application has so many other functions for your car but I haven’t tested it yet and also tells you of faulty codes if you have any.
I have to say that if you are looking for a scan tool that does work with the iOS Operating Sys, give this Autel MaxiAP AP200 a try..! Totally Satisfied. I would definitely recommend this.
