What is a Dacia Duster Prestige II airbag control unit?
The Dacia Duster Prestige II airbag control unit is the central safety unit in your vehicle, precisely deploying all occupant restraint systems, especially the airbags, in the event of a collision. It continuously monitors sensors, stores relevant crash data, and ensures the proper functioning of all connected airbag modules for maximum occupant safety.
This module is crucial for passive safety and controls the entire SRS (Supplemental Restraint System) in the vehicle. It receives signals from impact and acceleration sensors to activate the airbag pyrotechnic igniters within milliseconds in the event of an accident.
The airbag control unit is also responsible for the seat belt tensioners and communicates with other vehicle systems via the CAN bus. Proper functioning is therefore essential for your safety.
Why is the Dacia Duster Prestige II airbag control unit defective?
A Dacia Duster Prestige II airbag control unit can fail for a variety of reasons, often due to an accident, water damage, aging of internal components, or voltage spikes in the electrical system. Because it stores specific data after a crash, it often needs to be reset or replaced to restore full functionality of the safety system.
Water ingress or moisture is a common cause of control unit failure, as it causes corrosion on sensitive electronic components. This often leads to internal short circuits or communication errors.
After an accident, Dacia airbag control units irreversibly store crash data, preventing them from being used again without professional repair or replacement. A professional Dacia Duster Prestige II airbag control unit repair can remedy this.
Common error codes for Dacia Duster Prestige II airbag control unit repair
When diagnosing a faulty Dacia Duster Prestige II airbag control unit, specific error codes may occur that indicate internal problems or communication difficulties. Reading these codes is the first step in identifying the cause of the fault and initiating the necessary Dacia Duster Prestige II airbag control unit repair.
- B1000 → Control unit communication error → The airbag control unit cannot communicate correctly with the vehicle network, often caused by wiring or internal malfunction.
- B1015 → Faulty Airbag Module → The airbag control unit itself is internally defective, which requires inspection or replacement of the module.
- B1139 → SRS module fault → A general internal fault in the airbag control module that cannot be specifically attributed to a sensor or actuator.
- B1206 → Airbag RCM error → A defect in the Restraint Control Module (RCM), i.e. the airbag control unit, often after a crash or in the event of an internal defect.
- B1342 → SRS Error → A general error in the Supplemental Restraint System, reported directly by the airbag control module.
- B1620 → SRS Error → The airbag control module reports an unspecified error within the SRS system that requires precise diagnosis.
- B1649 → Crash detected (control unit error) → The airbag control unit has detected an accident and saved crash data, which requires a reset or replacement of the unit.
What part numbers are available for the Dacia Duster Prestige II airbag control unit repair?
For a successful Dacia Duster Prestige II airbag control unit repair, exact OEM part numbers are crucial to ensure the compatibility of the replacement part or repair with your vehicle. The two primary, multi-verified original Dacia part numbers for the airbag control unit in the Dacia Duster II Prestige are 985100209R and 985105129R.
These part numbers are specific to the airbag control unit of the second-generation Dacia Duster and ensure seamless integration. They are listed as original parts and fit your SUV model.
Other part numbers that occasionally appear are not sufficiently verified or do not apply exactly to the Prestige II variant, which is why the use of the mentioned OEM numbers is strongly recommended for the Dacia Duster Prestige II airbag control unit repair.

Dacia Duster Prestige II Airbag Control Unit: Functions & Technical Details
The Dacia Duster Prestige II airbag control unit is a highly sensitive electronic module that acts as the brain of the airbag system, ensuring the safety of all vehicle occupants in the event of a collision. It is responsible not only for airbag deployment but also for monitoring and diagnosing the entire passive safety system, including the seatbelt pretensioners and crash sensors.
The control unit operates on a 12-volt electrical system and communicates with sensors and other vehicle control units via the CAN bus. In an emergency, it pyrotechnically triggers the gas generators to deploy the airbags in seconds and protect the occupants.
It stores important crash data and error codes that must be read for professional diagnosis and repair. A Dacia Duster Prestige II airbag control unit repair often involves deleting this data or cloning the software.
Professional Dacia Duster Prestige II Airbag Control Unit Repair and Diagnostics
A professional Dacia Duster Prestige II airbag control unit repair is essential after an accident or failure to restore full functionality of your safety system and deactivate the warning light in the dashboard. Professional diagnosis and repair at a specialized workshop are crucial, as the airbag control unit is a safety-critical component whose improper handling poses risks.
Specialists can read the faulty control unit, interpret error codes like B1015 or B1649, and take appropriate action. This often involves erasing the crash memory or cloning the original software onto a replacement unit.
Avoid attempting to repair the airbag yourself, as this could lead to malfunctions or accidental airbag deployment. For Dacia Duster Prestige II airbag control unit repairs, rely on experienced specialists who have the necessary knowledge and equipment.
Regular diagnostics and maintenance can also help detect failures early and repair them preventively before they become a serious safety risk.
