Been having this same exact issue since 2 or 3 days. It's annoying because the airbag defect light comes on with a chime, stays a bit, goes off, and then every time it comes on again it chimes. Wouldn't be too bad if it would just chime once and then just have the sensor light stay on until you shut down the truck. But it just keeps getting on intermittently, every 1 or 2 minutes...I have been out of town for a week or so and now that I am back my service airbag system light keeps going on and off randomly while driving. Anyone else have this happen?
That was just a coincidence. Whether the seatbelt is fully retracted or not has no bearing on the airbag. There is a switch in the female part of the seatbelt receptacle that will sense whether the seatbelt is buckled or not but that's it.I had the same problem. I did what others suggested. I check the fuse, the harnesses under the seat. The warning light would come on in the morning only when I started the truck. I remember someone in the forum talking about seatbelt. I look over to the passenger side and saw that the seat belt was not fully retracted. It was hung up on the seat, I pushed it off the seat. The light has not come on since. It has been over a month now.
