Why is the airbag indicator light constantly on in a car?

[ReedLynn]

Reasons for the airbag indicator light staying on in a car: 1. Instrument self-check: When entering the vehicle and starting the ignition, the instrument panel performs an automatic check. The airbag light will automatically turn off after the self-check is completed, which usually takes about 5 seconds and is a normal phenomenon. If the airbag light remains on for a long time after the self-check, it can be determined that there is a genuine fault. 2. False fault: If the battery is low on power, it can also cause the airbag light to illuminate. Additionally, the airbag system may feedback a signal indicating low pressure in 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 reasons are ruled out, it may indicate a wiring fault, which should be repaired promptly. Possible causes of this fault could include issues with the airbag itself, collision sensors, airbag clock spring, or other wiring-related problems.
