Shows error 01221 and 01222. errors are not deleted. I looked at all the connections from the airbags to the sensors, everything seems to be ok. How to remove the error?   **Answer** If the vehicle was in an accident then the airbag module needs to be reset. We can do that at [MyAirbags.com](http://MyAirbags.com). But if the airbag light just came on one day without an accident then it could be bad wiring, bad sensors or the airbag control module has failed and may need to be replaced.
