How to solve SRS system malfunction?
2 Answers
SRS system malfunction requires using a decoder to read the fault code and perform repairs based on the fault code. Relevant information about the SRS system is as follows: 1. SRS refers to the airbag. 2. When the airbag warning light on the dashboard illuminates, it indicates that the airbag system failed the startup self-test and has issues. Relevant information about airbags is as follows: 1. Airbag: It is a vehicle occupant restraint system that uses an airbag designed to inflate rapidly during a collision and then quickly deflate. 2. Components: It consists of an airbag cushion, flexible fabric bag, inflation module, and impact sensor. 3. Principle: During a collision, the vehicle's impact sensors provide critical information to the airbag electronic control unit (ECU), including collision type, angle, and severity. Using this information, the airbag ECU's collision algorithm determines whether the collision event meets deployment conditions and triggers various ignition circuits to deploy one or more airbag modules inside the vehicle.
I've encountered this issue several times. SRS stands for the Supplemental Restraint System (airbag system), and you need to be extra cautious when the dashboard warning light is on. Last time my car had this problem, I first checked if the yellow wire connector under the driver's seat was loose—this area is prone to poor contact after prolonged bumps. Then I tested whether the clock spring in the steering wheel was faulty; if there's abnormal noise when turning the wheel, it's most likely broken. Also, try reseating the sensor connector under the rear seats. If all these components are intact, you should use professional diagnostic equipment to read the fault codes—regular OBD scanners can't read the airbag system. In the end, it turned out to be a faulty crash sensor, and replacing it fixed the issue. Don't tamper with the airbag system yourself; live wires might accidentally trigger it. The safest approach is to take it directly to a repair shop.
