Ttied to get my 2000 chevy blazer inspected but 3 shops all said they would reject it becouse the airbag light come on for a few seconds everytime i break. It has done this for as long as i rember.

 

The most common cause is that one of the two front sensors is bad. A high-end scan tool can read the error code. My local O'Reilly's auto parts was able to do the scan for me.

The fix csn be getting a replacement at a wrecking yard.
