If the SRS warning light on your car is on, it means that one or more elements of SRS system malfunctioned.

SRS (Supplementary Restrain System) is a supplementary system to assure a safety of passengers. The system contains of about 20 elements, that can be divided into 3 groups:

• crash sensors: triggered if a collision occurs;

 • airbag control unit: receives information from the crash sensors, calculates severity of the impact and deploys elements of the safety system accordingly;

• actuators - among them:

- airbags,

- seat belt pre-tensioners,

- seat occupancy sensor, and many others.

The fact that the SRS is lit on is not enough to diagnose a faulty seat occupancy sensor. To find out the cause, you need to check the car with a professional diagnostic software.

ATTENTION! Free and cheap diagnostic softwares might falsely indicate malfunctions of SRS elements.

ATTENTION!  An unqualified mechanic, even using a professional software, may incorrectly diagnose a car with a false error.
