Impreza WRX F4-2.0L DOHC Turbo (2004)
AIRBAG SENSOR
The safety sensor and electric sensor are incorporated into the airbag control module and the side airbag sensors.
The safety sensor is also a pendulum type sensor. If the sensor receives a frontal or side impact exceeding a certain limit, the mass in the sensor moves in
the direction opposite to the impact direction to turn the switch ON.
The electric sensor consists of a semiconductor type sensor which senses the deceleration caused by collision in terms of change in the electrical
resistance of the impact sensing circuit.
