What is a Seat Mii Mk1 airbag control unit?
The Seat Mii Mk1 airbag control unit is the central safety unit in the vehicle, continuously monitoring the entire airbag system. It detects accident situations using connected sensors and reliably activates airbags and seatbelt pretensioners as needed to provide optimal occupant protection. It also stores important crash data.
This electronic component is crucial for the passive safety of the first-generation Seat Mii, built between 2011 and 2018. It ensures that all restraint systems are deployed precisely and quickly in an emergency.
After an accident or system errors, important information is stored in the control unit, enabling targeted diagnosis and repair.
