Some late model Subaru vehicles are equipped with an air bag system, to supplement the safety belts. When an impact at the front of the vehicle is greater than a set level in the air bag sensor, the sensor senses it and generates an electrical pulse to inflate the bag in the air bag module, preventing the drivers body from contacting the steering wheel.
The SRS air bag consists of an control unit, left and right front sensors, 2 safety sensors built into the control unit and an air bag module containing an air bag and inflator. The left and right front sensors and the 2 safety sensors are connected in parallel respectively, and the front sensors and safety sensors are connected in series, so the air bag will inflate if at least 1 front sensor and 1 safety sensor sense an impact at the same time.
The components of the SRS system are not owner serviceable and no attempts should be made to repair the system, however, when working on any of the electrical systems inside of the vehicle, the air bag system must be disarmed. This can be accomplished by following the disarming procedure given in this section.
NOTE: All SRS electrical wiring harnesses and connections are covered with yellow outer insulation.
