I have a 1993 Ford Aerostar flashing an airbag code of 12. My son said it started when the car wouldn't start due to a weak battery and corrosion. My son for an unknown reason started pulling fuses to check for blown ones. When the fuses were replaced the airbag light began to blink while driving indicating a 12 code. Also on another note, when I turn the key to the "accsesory" position, back one click from off, there is a buzz which sounds about every second. The buzz goes away when key is in "on" or "start" position. I do not know if the airbag code and buzzing are related. The airbag light does not flash when key is in "accsesory" position.
