Impact Sensor: Description and Operation

FRONT SUB SENSOR
One front sub sensor is installed on both left and right sides ahead of the front wheel apron wall. Front sub sensor is the pendulum type sensor. If the sensor receives a frontal impact exceeding a certain limit, the mass in the sensor revolves forward to turn the switch ON.




SAFETY SENSOR AND ELECTRIC SENSOR
Safety sensor and electric sensor are built into the airbag control module and side airbag sensor.

Safety sensor is the pendulum type sensor. If the sensor receives a frontal impact exceeding a certain limit, the mass in the sensor revolves forward to turn the switch ON.

Electric sensor consists of the semiconductor type sensor which senses the deceleration at collision by the change of the electrical resistance and the impact sensing circuit.
