How is the airbag light turned on in winter?

Airbags are generally composed of sensors, microprocessors, electronic control units, airbag covers and support rings, airbags and airbag modules. The airbag indicator still flashes or stays on for 6-8 seconds after the vehicle is started, or the airbag indicator flashes for 5 seconds after the vehicle is driven, indicating that the airbag may be faulty.

There are many reasons why the airbag light is on, such as the steering wheel hairspring fault, the airbag sensor is loose or poorly contacted, the airbag body fault, the airbag ECU circuit fault and so on. These failures can not be confirmed by simple disassembly and inspection. It is necessary to read the failure code with a diagnostic instrument and check it step by step, then repair or replace the failure point, and then eliminate the airbag failure light on the instrument panel after completion.
