For some vehicles, the airbag sensors may be located throughout the vehicle. They are also commonly found behind the front fender in the front of the vehicle.
How does an airbag controller work in a car?
Airbag Control Unit. Upon signal of a collision, the controller interprets the electrical input and measures the level of collision to determine the release of an airbag. In the event of one impact sensor and safety sensor being closed, an electrical current is transmitted to an airbag module which contains the airbag and inflator assembly.
What causes the airbag light to flash on the dashboard?

Where is the airbag control module located?
The location of the airbag module differs from vehicle to vehicle depending on the make and model of it. In some vehicles, it is located in the center console, kick panel, under the radio, or behind the steering wheel.
Where is the SRS module located?
First, find the SRS computer module, which is typically located beneath the center console between the two front seats. In some cars, it can be found in the center of the dash on the floor. In GM cars, the SRS computer module is located beneath the driver or passenger seat.
How are airbags fixed after an accident?
After an accident occurs, airbags are fixed by resetting the sensors and replacing the airbag unit. Most modern vehicles will not allow you to reset an airbag for safety precautions, and instead, you must replace it entirely. This requires removing the old airbag from the driver or passenger side and installing a new one.
There are two main types of airbag sensors in modern vehicles. Mass sensor systems are typically located in the front of the vehicle and measure impact. Usually there will be one sensor inside the engine and another somewhere in the passenger seating area.
When does the airbag seat belt sensor come on?
The airbag seat belt sensor or light is on all the time it’s common for these types of vehicles of 2004 to 2008.

An object in motion stays in motion unless acted upon by another force. That other force is provided by your airbags (as well as your seat belts). Your impact sensors are actually activated by the same inertia that you would experience in a collision.
There are two main types of airbag sensors in modern vehicles. Mass sensor systems are typically located in the front of the vehicle and measure impact. Usually there will be one sensor inside the engine and another somewhere in the passenger seating area.
Airbag sensor replacements typically cost around $250-$350, and it’s generally recommended to have an expert mechanic complete the job, given how important and sensitive the repair is.
