A vehicle’s safety features and functions can leave you wondering exactly how the SRS Airbag System works. One of the common questions we are asked is whether or not the seat belt tensioners can go off if the airbags have not deployed. To better understand this question, it is important to first know what the basic safety features of a vehicle are. The SRS refers to the vehicle’s supplemental restraint system and consists of both the airbags and the seat belt tensioners. When a car is involved in a collision or an accident, the SRS airbag module is the component that communicates with the airbags. The airbag module must determine, instantaneously, which airbags in the vehicle must deploy and/or if airbag deployment is necessary. It is critical that the proper airbags deploy, since airbags are responsible for preventing serious injury or death. The airbag module is significant because it prevents an airbag from unnecessarily deploying. If an airbag goes off for a seat that is not occupied, for example, that would be a waste of the airbag and would cost a great sum of money for a replacement. Therefore, the airbag module operates to ensure that the proper airbags go off at the right time. The seat belt tensioners are also a key component of a vehicle’s SRS, and can be seen as the vehicle’s front line of defense. When the sensors detect an accident, the seat belt tensioners engage, set off by an explosive charge. Once this explosive charge goes off, the piston quickly wraps the fabric strap of the seat belt around a spool. This rapid retraction removes any slack from the belt and pulls the passenger firmly into their seat before the vehicle experiences the full force of impact. The seat belt tensioners properly position the passengers so that they are ready for the airbag deployment. The seat belt tensioners and the airbag system work together to ensure the safety of all passengers. However, is it possible for the tensioners to go off if the airbags have not? The answer is yes — a vehicle’s seat belt tensioners can be deployed even if the airbags have not activated. In some situations, an accident or collision can be minor enough to not require airbag deployment, but significant enough to set off the tensioners in order to secure the driver and passengers. However, drivers should be aware that if the airbag light is turned on, this could signal a malfunction with the airbag or SRS system that must be addressed immediately.
