What is a BMW 2 Series U06 Active Tourer airbag control unit?
The BMW 2 Series U06 Active Tourer airbag control unit is the central control unit for the vehicle's safety systems. It continuously monitors sensors, detects the need for deployment in the event of an impact, and precisely activates all passive safety elements such as airbags and seatbelt pretensioners. This component is crucial for occupant protection.
It acts as the "brain" of the restraint system by continuously processing data from acceleration and impact sensors.
In the event of an accident, the control unit decides in milliseconds which airbags and belt tensioners need to be deployed to optimally protect the occupants.
