SRS Airbag Construction and Operation – Front airbag sensor


The front airbag sensors are mounted on the right and left front side members.
The sensors cannot be disassembled.
The front airbag sensors detect the impact from the front and send the deceleration signal to the center airbag sensor assembly.
The deceleration sensor is stored in the front airbag sensor.
There are two types of deceleration sensor: a type made from a semi-conductor and a mechanical type that uses an eccentric rotor.
There used to be a type that had no front airbag sensor and controlled the front airbag system only with the center airbag sensor assembly.
