Assuming you have a Jeep TJ with an airbag light that is on, there are a few things you can do to try to turn it off. First, check the fuse box under the hood and see if the fuse for the airbags has blown. If it has, replace it and see if that turns the light off. If not, there could be a problem with the airbag sensor or wiring. In this case, you'll need to take it to a mechanic or dealership to have it diagnosed and repaired.
