What can cause an airbag light to come on?

In Safety by Steves Auto Repair and Tire

Airbags are an important safety feature that protect you and your family in case an accident occurs.

Sometimes, the airbag light will come on. This occurs whenever the airbag system senses a problem. 

The light can turn on for a few reasons.

What can cause the airbag light to turn on

Airbag module is damaged: An airbag light can turn on if the airbag module, which stores information, is damaged because of rain or flooding. If this is the case, the airbag module will need to be replaced.

Airbag backup battery needs recharging: Has your car battery died recently? If so, the backup battery for the airbags could have drained with it. The issue may become resolved when the car battery is charged, or the airbag backup battery might need to be recharged. 

Sensor not working: There are various sensors connected with parts of a car, including the airbag. For example, some vehicles have a sensor that measures the weight in the passenger seat. If a sensor is going bad, the airbag light could be triggered.

Bad airbag clock spring: Vehicles have an airbag clock spring that links the steering wheel with other components, such as the airbag. The airbag clock spring could stop working properly.

Other problems that may trip the airbag light include a broken wire and a bad resistor in the seat belt buckle.
