Your vehicle will require an airbag scan tool for the proper diagnosis.
Once you have the fault code you will know what to replace.

Here's a site that will explain everything you need to know about airbag lights and resetting the system.
Although it’s a pay site ($14.95/day), it’s a lot cheaper than going to the dealer

On most vehicles, the airbag light should come on for @6 seconds, and then go off if the system is working properly. If there is a fault or a problem in the system, the light will remain illuminated, or flash continuously. If the airbag light does not work properly, some vehicles have an audible tone that sounds indicating a problem with the airbag light system. When the light is on (or the tone is sounding), the airbag will NOT deploy, even in an accident.
The flashing light on your car is telling there is a problem. On some vehicles, the light is flashing a two digit code. Once you know the code, you can most likely repair it yourself. There are fairly easy procedures that most people are capable of repairing.
Some vehicle manufacturers accommodate systems without a scanner (like Toyota, Lexus, Nissan, Infinity, Honda, Acura, Ford, Lincoln, Mazda & Mercury) .
Most all other vehicles require a scan tool for the diagnosis.
