Impact Sensor: Description and Operation
Function
The side airbag sensors sense the acceleration acting in the lateral direction of the vehicle in the event of a side collision and initiate a logic check in the
ETR control module with airbag (N2/2). If the values coincide a triggering signal is sent to the side airbag squibs (R12/9 and R12/10).
