My airbag light is on in my car don't no why but how do i get it to go off

 

You have to provide some diagnostic information, error code?! I had on mine once, after hard breaking, i got the light on. After few days I figured out how to read Airbag module, and got error for left door sensor. Tested it with ohm meter, and it showed open circuit. SO after replacing sensor, i had to go to dealer to reset the light. That's my case.
