We just bought a 2005 Mazda 6, for my daughter. The airbag light goes on when the passenger seat belt is buckled.
At first it flashes....it flashes 5 times, pauses then flashes 2. Then a long pause, then repeats the "5", "2" flash...After awhile the light stays on constant.
Any Suggestions
Thanks
Barry

 

There is a fault somewhere in the system. You need to get a diagnostic code check.
