What happened to the airbag light?

The reason why the airbag light is not on: 1. The instrument self-test instrument will automatically test within a short time after entering the car to strike a fire. After automatic detection, the airbag light will automatically go out, which is normal for about 5 seconds. If the airbag light is still on for a long time after the self-inspection, it can be judged that there is a real fault; 2. False fault If the battery is dead, the airbag light will also light up. And the airbag will also feed back a signal of low air pressure of an airbag to generate a fault code. At this point, just clear the fault code; 3. If the above two reasons are really eliminated, it is possible that the faulty line should be repaired in time. The causes of this failure may be linear failures such as airbag, collision sensor and airbag hairspring.
