Everything was fine until my battery died. Then I stored the car for 2 months with the battery out. Finally bought a new one, installed, then suddenly the airbag light is on. Can't clear it with PA Soft 1.4 or B800 tool. Both tools go through the process of clearing but codes stay. I know nothing is wrong with the bags. (Recalls were all done and no new work has been done) Any ideas what this could be? Thanks.
