Why is the airbag light on in a sedan?

[LaCharlotte]

The airbag indicator light shows the working status of the airbag system. It usually performs a self-check when the car is started, and the light should turn off after a few seconds. If the light stays on, it indicates a fault in the airbag system, which should be addressed promptly. The following situations may cause the light to illuminate: 1. Instrument panel self-check: When entering the car and starting the engine, the instrument panel will perform an automatic check. The airbag light will automatically turn off after the self-check is completed, usually within about 5 seconds. This is a normal phenomenon. If the airbag light remains on after the self-check, it can be determined that there is indeed a fault. 2. False fault: If the car battery is low on power, it may also cause the airbag light to turn on. Additionally, the airbag system may report a low-pressure signal from a specific airbag, generating a fault code. In this case, simply clearing the fault code will resolve the issue. 3. Genuine fault: If the above two causes are ruled out, it may be due to a wiring issue, which should be repaired immediately. Possible causes of this fault may include problems with the airbag itself, collision sensors, airbag clock spring, or other wiring-related faults.
