do your steering wheel controls still work? (for the radio, if so equipped) or do they work on and off with the air bag? i feel like a broken record here......
i had mine car scanned at a garage my friend works at. some shops wont have the scanner, its not cheap to own. but every auto body shop under the sun will have a airbag scanner in the shop, they need it all the time. most will charge you.
the free autozoze scanner is hit or miss, worth a shot, but chances are it wont read a srs code.
same deal goes for abs codes, hit or miss at the az, most need a scanner only a garage will have.
