What does the airbag control unit 971 959 655 do?

The 971 959 655 is the airbag control unit that evaluates the sensor signals in the restraint system (SRS) of Porsche. In an accident it decides within milliseconds which airbags and seatbelt pretensioners are triggered, and it monitors the system continuously.

The control unit reports faults via the airbag warning light in the instrument cluster. After an accident it stores crash data and locks itself.
