4.8What is a Renault Kadjar I airbag control unit?
The Renault Kadjar 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 to provide maximum safety.
This electronic control unit, also called the airbag ECU, is responsible for continuously monitoring critical vehicle data.
In the event of a collision, it ensures the precise and timely deployment of airbags and seat belt tensioners.
Why is the Renault Kadjar I airbag control unit defective?
The Renault Kadjar I airbag control unit often becomes defective because crash data is irretrievably stored after an accident or internal electronic errors occur. In this case, the airbag warning light remains permanently illuminated, and the system is deactivated, requiring immediate repair of the airbag control unit.
Typical causes of failure are water damage, short circuits or age-related material fatigue of the electronic components.
A defective control unit prevents the passive safety systems from functioning properly and must be repaired or replaced immediately.
Common error codes for Renault Kadjar I airbag control unit repair
When diagnosing a defective Renault Kadjar I airbag control unit, specific error codes will appear that point directly to the control unit. These codes indicate communication problems, internal module errors, or general system malfunctions that require repair.
- B1000 → Control unit communication error → Signal interruption or internal defect in the airbag ECU.
- B1015 → Faulty airbag control unit → Internal malfunction of the control unit hardware or software.
- B107E → Airbag module error → Malfunction within the airbag control unit or its initialization.
- B1139 → Airbag SRS system error → General malfunction in the safety restraint system, often originating directly from the control unit.
- B207F → SRS unit (control unit) error → Critical error of the SRS control unit, which affects operation.
Codes such as "Crash Data Stored" are status messages after an accident that must be cleared before the airbag control unit can be repaired.
What part numbers are available for the Renault Kadjar I airbag control unit repair?
To ensure compatibility and safety, only verified OEM part numbers should be used to repair the Renault Kadjar I airbag control unit. These numbers are specific to the Kadjar I airbag control unit and exclude other components such as sensors.
The following numbers have been confirmed multiple times by trusted sources and are relevant for the first generation of the Renault Kadjar:
- 985100781R (Renault Original OEM)
- 632199700 (Renault Original OEM)
- 985108564R / 632199700C (Renault Original OEM)

It is crucial to use only these exact numbers for the Renault Kadjar I airbag control unit repair.
Third-party part numbers or numbers from other Renault models are not verified for the Kadjar I and should not be used.
Important aspects of Renault Kadjar I airbag control unit repair
Repairing the Renault Kadjar I airbag control unit includes erasing crash data, correcting electronic errors, and conducting a comprehensive functional test. The repaired control unit comes back with all vehicle data and is immediately ready for use after reinstallation – no coding required.
A repaired airbag control unit is tested for full functionality and reset to its original state.
The repaired control unit communicates correctly with the vehicle systems immediately after reinstallation, since it retains all vehicle-specific data unchanged – no additional programming required.
The installation location is usually under the center console or the passenger seat, which requires professional removal.
Another important step is checking the yellow-marked connectors, which ensure a secure connection to airbags and sensors.
Advantages of Renault Kadjar I airbag control unit repair compared to new purchase
Repairing your Renault Kadjar I airbag control unit offers significant cost savings compared to purchasing a new replacement part. It's also a more sustainable option, as it reuses working components and ensures the original quality of the component after successful repair.

This service is an efficient solution to quickly get your vehicle back on the road without having to wait long for a new part.
Repair is an environmentally friendly alternative that conserves resources and reduces waste.
