What is a Dacia Sandero Stepway II airbag control unit?
The Dacia Sandero Stepway II airbag control unit is the central safety unit in the vehicle. It continuously monitors airbag sensors, detects impact situations, and, in an emergency, rapidly activates all occupant restraint systems such as airbags and seatbelt pretensioners to ensure passenger safety.
This electronic control unit is essential for the functionality of the passive safety system. It is usually located in the lower part of the dashboard, easily accessible behind the trim panel. If a malfunction occurs, the airbag warning light in the cockpit illuminates.
