What is a Skoda Octavia Tour Mk1 airbag control unit?
The Skoda Octavia Tour Mk1 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It precisely monitors sensors, stores relevant crash data, and ensures the immediate and proper functioning of all airbag modules in the vehicle for maximum safety.
This critical component is responsible for detecting an impact using connected crash and lateral acceleration sensors. If necessary, it reliably deploys the airbags and seatbelt pretensioners to protect the occupants.
Proper functioning of the control unit is essential, as it forms the heart of the passive safety system. It also communicates with other vehicle control units via the CAN bus and stores relevant system errors.
