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.

As an experienced car enthusiast, I believe diagnosing airbag malfunctions requires a step-by-step approach. Start with basic checks: inspect whether the 15-amp SRS-labeled fuse in the fuse box has blown. Then carefully examine the crash sensors under the chassis and windshield for water damage or corrosion. Seatbelt pretensioners are also prone to failure - poor connector contact can trigger error codes. If the clock spring in the steering wheel fails, it won't just illuminate the airbag light but may also disable the horn. The most troublesome issue is control module failure, which requires professional diagnostic equipment. I strongly advise against using online reset methods to forcibly clear fault codes - this doesn't address root causes and could be more dangerous. If you can't identify the problem, visit a dealership to read historical fault records; their equipment can pinpoint exactly which component is malfunctioning.

Never ignore the airbag warning light! First, check if any spilled drinks or water under the seats have caused sensor short circuits. Then inspect all seatbelt buckle wiring harnesses to ensure they haven't been kicked loose. Changes in the clock spring assembly's resistance inside the steering wheel can also trigger fault codes. Extra caution is needed if seat covers were installed or wiring modifications were made. Always use a diagnostic tool to check fault history - residual data from minor collisions might remain uncleared. These electronic systems are highly sensitive; even contact point oxidation can cause false alarms. We recommend a full vehicle scan at an auto repair shop - address minor issues immediately, and replace any damaged major components without delay.

The airbag system is a closed-loop circuit, and it only functions properly when there's a complete connection between the crash sensor and the gas generator. If it malfunctions, first check if the main control box connector behind the glove compartment is loose. The pressure sensor under the passenger seat rail is the most fragile and can be easily damaged by prolonged heavy weight. A disconnected circuit in the pyrotechnic trigger device inside the seatbelt buckle can also trigger the warning light. In some older cars, the issue is caused by aged wiring leading to excessive resistance, which the control computer then interprets as a fault. Don't believe in the old trick of disconnecting the battery to reset the system—it's only a temporary fix. Using a diagnostic tool is the most reliable method, as it can distinguish between a faulty sensor and an open circuit. The most common false alarms I've seen are due to poor ground wire contact, which can often be resolved by simply resecuring it.
