Purpose



The side airbag sensors (A53/1 and A54/1) sense the acceleration/deceleration acting on the vehicle in the lateral direction and cause the airbag control module (N2/7) to perform a plausibility check. If the values are plausible, an actuation signal is sent to the affected side airbags/window airbags.
