97 Lumina HELP with AIR BAG LIGHT

I have a 1997 Chevy Lumina and need help! I replaced the shift solenoids in the tranny and didn't disconnect the steering shaft. Well, it pulled apart and I was unable to steer, spun the steering wheel several times with it disconnected. No that I have it back together, the air bag light is on constantly. What did I do? How can I read the code for this, if possible? I have a diagnostic (obdII) scanner and it reads no codes. Is this going to be possible for me to fix at a reasonable cost? Please help!

Thanks,
