There could be many reasons for the light to come on. it could be a seatbelt buckle switch or a fuse or clockspring etc, the best way to check it is to have the airbag computer scaned for codes, these codes tell you whats not working then you can check it from there,but it tells you what part of the system is bad, like the code can say seatbelt circuit, or front crash sensor. so have it scanned first.
