When I first got my car, I had to pull the steering wheel to replace the turn signal lever assembly, and the air bag light was on after I was done. All I did was unplug it to remove the steering wheel, and then plug it back in during reassembly. What do I have to do to get the light turned off? I thought it came on becasue it was tampered with, and maybe has to be re-set with a scan tool or something. Any Ideas on this?
