Airbag control unit with part number 9661890280

What does the airbag control unit 9661890280 do?

The airbag control unit 9661890280 coordinates the restraint system (SRS) for Peugeot. It processes the measured values from the crash sensors, decides in a crash within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. If it detects a fault, it indicates it via the airbag warning light.

The manufacturer number Bosch 0285001885 is additionally printed on the housing.

During operation the unit constantly checks the connected components.

After an accident it stores crash data and locks itself.
