Well, I don't know why it turned on. I took it to a shop. Unfortunately, the computer doesn't communicate with the scanner. Does anyone know if the airbag light is a common problem in these cars? I haven't changed anything in it. No battery change, no other electronics installed or taken out. The milllage is ~135Kmiles.
Also the computer doesn't respond to the scanner. This might become a more serious problem if the car has other issues in future.
would love to hear your comments/suggestions
