1, instrument self-check

It is normal that the instrument will automatically detect in a short time after entering the car to strike a fire. After automatic detection, the airbag light will automatically go out, which takes 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 failure

If the battery is dead, it will also cause the airbag light to 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, clear this fault code.

3. Actual error

If the above two reasons are eliminated, it is possible that the line has failed and should be repaired in time. The causes of this failure may be linear failures such as airbag, collision sensor and airbag hairspring.
