Impact Sensor: Description and Operation

SYSTEM OPERATION
The Driver and Passenger Airbag System is a supplemental safety device designed to help protect the driver and passenger from serious injury caused by a frontal impact of the vehicle.

The Airbag Control Module's (ACM) internal impact sensor provides verification of the direction and severity of an impact. The sensor is mounted within the ACM.

The Airbag Control Module (ACM) uses data collected from it's internal accelerometers to discriminate the direction and severity of an impact. The ACM will activate power stages internal to the module in order to deploy the driver and passenger side airbags once a predetermined threshold has been exceeded. The ACM is calibrated for a particular vehicle family and uses an advanced software algorithm to discriminate the severity and direction of any vehicle event.
