I have seen some comments about unplugging the battery, but I am not sure how to proceed.
COPPER is NOT Magnetic. Forget the hoax video. Get a magnet and try it your self.
Best thing to do is take it to the dealer. its a safety issue, even if you unplug the battery, the problem is not fixed.
Did someone steal the airbag? You probably need a new one. Not cheap. maybe $400
Have you hit anything with the front bumper, like maybe a snow drift. It is possible that the problem is just a sensor connection. Make sure to remove the fuse for the air bag/SRS system before testing any components. Some auto parts stores can recover the code and tell you what the code stands for, and most will do it for free. I Do Not recommend disconnecting the battery. Yes, it will clear the code, but now you don't know where the problem is. When the battery is disconnected on some vehicles, it will set a check engine light for charging system malfunction. Hope this helps and good luck. Christopher
