What is a BMW M6 F12 Coupé airbag control unit?
The BMW M6 F12 Coupé airbag control unit is the heart of the occupant protection system and precisely activates airbags and seatbelt pretensioners in the event of an accident. It processes sensor data in real time and stores crucial crash information, making it essential for the safety of vehicle occupants after an impact. This unit is crucial for a successful BMW M6 F12 Coupé airbag control unit repair.
This central safety unit, also known as the SRS module, continuously monitors the vehicle's condition. It is networked with other systems via the CAN bus to initiate coordinated protective measures in the event of an accident.
It evaluates acceleration sensors and crash sensors to assess the need for airbag deployment. The unit ensures that airbags and seatbelt pretensioners are deployed instantly and provide optimal protection for the occupants.
