Task 

• The sidebag and windowbag sensors determine the acceleration values, which occur in the area of the B-pillar of the left or right side of the vehicle, in order to recognize a side impact early on.
• After a successful self-test, the success is confirmed by the sidebag and windowbag sensor by transmitting a signal to the restraint systems control unit (N2/7).
• If the self-test fails four times, a defective sidebag and windowbag sensor is signaled.
• Upon request of the restraint systems control unit, the measuring range and the sensitivity of the sidebag and windowbag sensor are transmitted, and it is checked whether they match the programmed equipment. The production data can be output via STAR DIAGNOSIS.
• The acceleration values are transmitted periodically as a digital value.
