Occupant sensors are located in the seats and detect whether there is a person sitting in the seat. Seatbelt sensors are located in the seatbelt buckle and detect whether the seatbelt is fastened.

Impact sensors are typically located at the front of the vehicle and detect the force of an impact. There are several different types of sensors in the airbag system of Outback, including impact sensors, seatbelt sensors, and occupant sensors.

If one of these sensors is damaged or malfunctioning, it can cause the airbag light to turn on. The airbag system relies on a network of sensors to detect a crash and deploy the airbags. One of the most common reasons for the airbag light to turn on in Outback is a faulty sensor.
