B0014 Chevrolet -

Question

I had Diagnostic Code B0014. I got this code through my On-star Diagnostics. On my DIC display it says service airbag. It comes and it goes and sometimes it is steady on. Earlier about a few months ago a deer hit me on my driver's side. I had damage repaired through a highly recommended body shop. I told them when it first came on and was told that they had nothing to do with the airbag system. I am looking for answers.
Thank you
