Hi, I have an 07 Corolla, got hit from behind while at stoplight, no damage but after getting back in car airbag light was on. It appears as if the passenger seat does not recognize when someone is seated there. Usually it beeps if the passenger is in the seat without a seatbelt on, and it no longer does that. Any ideas? I am going to get it scanned at the dealer in a couple weeks, I have heard it might just need a scan and to be recalibrated...
