The Airbag Control Unit (ACU) is the central nervous system of your vehicle's passive safety system. It receives data from various sensors throughout the car, such as impact sensors, seat occupancy sensors, and seatbelt pretensioners. Upon detecting a collision, the ACU processes this information in milliseconds and determines the appropriate response. This includes deploying the airbags, activating seatbelt pretensioners, and potentially sending signals to other safety systems like electronic stability control. A malfunctioning ACU can compromise the entire airbag system, leaving occupants vulnerable in an accident. This specific control unit, part number 8216E0, is designed and manufactured to the high standards expected from PEUGEOT/CITROEN, ensuring compatibility and reliable performance. Replacing a faulty unit with a genuine part is essential for maintaining the integrity of your vehicle's safety features.
