Drivers seat back rest air bag randomly deployed when I was in park, in my driveway taking my seat belt. Bruised my arm/ side of body pretty good. I had no idea how that could happen however, I connected my scanner tool to the car and come to find out I had 7 air bag/srs codes. After that happened all of my seat belts locked up, and per the scanner, it says a few other air bags have deployed but they haven't. This happened a while ago, (wife's car) and I haven't had time to reach out about it. I still drive it just to work and back but I disconnected the srs module in fear of the air bags the scanner tool said deployed WILL deploy while I'm driving. No previous codes or air bag light were shown before that occurred along with no previous repairs or modifications at the time were done besides regular maintenence. Hasn't been inspected but the light is still on, they're hard codes that can't be cleared, and the deployed air bag/seat back cover is still present.
