What is a Dacia Duster Prestige I airbag control unit?
The Dacia Duster Prestige I airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle. This essential component is vital to safety in the Dacia Duster.
This module is permanently connected to the vehicle electrical system and continuously monitors acceleration and impact sensors.
In the event of an impact, the control unit pyrotechnically triggers the airbags and belt tensioners to provide optimal protection for the occupants.
Why is the Dacia Duster Prestige I airbag control unit defective?
A Dacia Duster Prestige I airbag control unit can fail for a variety of reasons, often after an accident due to stored crash data or due to internal electronic errors and aging. A defective control unit will cause the airbag system to stop functioning and the SRS warning light to illuminate, requiring immediate Dacia Duster Prestige I airbag control unit repair.
After an accident, the control unit stores irreversible crash data that prevents further deployment until a specific repair is carried out.
Internal short circuits, overvoltage damage or age-related wear and tear of the components can also lead to failure, which requires a precise diagnosis.
In such cases, professional repair or replacement of the module is essential to continue protecting vehicle occupants.
