Hello all my 98 Cherokee limiteds bumper is pushed in a little bit, you couldn't tell unless your looking directly at it. And the airbag light is on and nothing is physically wrong with the jeep at all. Should I replace the impact sensor in the back? If so how do I do it? Thanks guys!!

 

Does horn work? If horn doesn't work, you need to check clockspring by multimeter.
Call local repair shop to find out how much they charge for checking airbag codes. They will tell you if module is bad. Sensor is inside module (rear of center console)

 

I replaced the clockspring and nothing changed, but ok thanks lol.
