If the toyota 4runner passenger airbag is light blinking, what is the problem?

The passenger airbag light blinking on a Toyota 4Runner can be due to a problem with the airbag sensor or the airbag module. The airbag sensor is basically a detecting device that can read rapid deacceleration of the vehicle and generates a signal as a response. Its basic function is to electronically communicate the information with the electronic control unit and all the equipment related to the airbag system.The airbag module is a computer that stores information. Thus, during a collision, the impact data is stored in the air bag module. If Your vehicle was in an accident, a collision, or You hit a curb or a pothole and the airbag light turned on, then the airbag control module will need to be reset.
