We have a 2008 Mazda CX9. The passenger side airbag warning light is on and won't go off. According to the manual, the light means it's not functioning, but we don't know why. Any help would be appreciated.

You had better take the Mazda back to the dealership to have the airbag tested. This function is too important to ignore. The airbag has to function.

Yeah you better take it to the dealer and have it looked at.
If someone that dosen't know what there doing messes with it and hits a wrong wire some where , than its going to cost a pretty penny to put back togather.
