What is a Dacia 1110 I airbag control unit?
The Dacia 1110 I airbag control unit is the central safety unit in your vehicle, continuously monitoring all occupant restraint systems. It reliably detects impact events using special sensors, evaluates these signals in real time, and activates the airbags and seatbelt pretensioners as needed to ensure maximum occupant safety in the event of an accident.
This crucial component also stores important crash data and reports any system errors via the airbag warning light in the instrument cluster.
A correctly functioning airbag control unit is essential for safety and is the heart of your Dacia's passive safety system.
Why is the Dacia 1110 I airbag control unit defective?
The Dacia 1110 I airbag control unit can become defective due to stored crash data after an accident, internal electronic errors, or communication problems in the vehicle's network. Such a failure inevitably leads to the activation of the airbag warning light and compromises vehicle safety, requiring immediate Dacia 1110 I airbag control unit repair to restore full functionality.
Common causes of a defect are physical damage after an impact, which leads to the storage of crash data and blocking the system.
Age-related wear and tear on electronic components, overvoltage or water damage can also lead to a failure of the airbag control unit.
Communication problems on the CAN bus, such as cable breaks or corrosion, can also impair the function of the control unit and cause a failure.
Common error codes for Dacia 1110 I airbag control unit repair
During Dacia 1110 I airbag control unit repairs, specific error codes may occur, indicating internal defects in the control unit or communication problems within the vehicle. These codes help specialists identify the exact cause of the malfunction and initiate the necessary steps for a successful repair.
- B1000 → Control unit communication error → The airbag ECU cannot communicate correctly with other systems.
- B1080 → Internal error in the airbag control unit / crash data stored → The control unit reports an internal defect or is locked after an accident.
- P1645 → CAN bus data bus defective / communication error → Communication of the airbag control unit via the CAN bus is disrupted.
- P1648 → CAN bus data bus defective → A general disturbance in the CAN bus data flow affects the airbag system.
- P1649 → CAN bus data bus ABS no signal → The airbag control unit is not receiving any signals from the ABS control unit via the CAN bus.
These error codes are crucial for accurate diagnosis because they directly indicate problems within the airbag control unit or its immediate communication channels.
Reading and interpreting these error codes requires specialized diagnostic equipment and expertise in a suitable workshop.
What part numbers are available for the Dacia 1110 I airbag control unit repair?
For the Dacia 1110 I airbag control unit repair, there are no clearly identifiable OEM part numbers available from public sources. Instead, compatible OEM numbers from similar Dacia models, such as the Logan or Sandero, are used, which have proven to be functionally equivalent in practice. However, a thorough check using the chassis number is strongly recommended.
Verified Dacia original OEM numbers include **985102865R** and **985106332R**, which are used in adjacent series.
The number **985102865R** is frequently mentioned for Dacia Sandero III and is listed multiple times in technical databases as an original part.
Another known OEM number is **985106332R**, which has been specifically confirmed for Dacia Logan airbag control units and is often compatible with older Dacia models.
Additionally, the supplier number **8201002829 / 28404802003** from Continental may be relevant, which often appears on used parts for Dacia Sandero.
To determine the exact part number for your Dacia 1110 I airbag control unit, you should always use the chassis number (VIN) and ask a Dacia dealer or professional TecDoc databases.
Dacia 1110 I airbag control unit repair or replace?
The decision to repair or replace a Dacia 1110 I airbag control unit often depends on the nature of the defect and the cost. A repair is often more cost-effective and environmentally friendly in cases of internal faults or crash data deletion, while a replacement is the safer and more long-term solution in cases of severe damage or complex system failures, and should always be performed by a specialist workshop.
A repair is usually useful if only crash data needs to be deleted or if there are minor internal errors that do not require replacing the hardware.
Vehicle-specific data is retained, and the costs are generally lower than purchasing a new spare part.
However, replacing the airbag control unit is necessary in the event of irreparable damage, such as moisture, short circuits or serious electronic defects that make it impossible to function.
Regardless of the option chosen, work on airbag systems must always be carried out by a qualified workshop due to their safety relevance.
Programming and adapting the control unit to the vehicle after the Dacia 1110 I airbag control unit repair or replacement is mandatory to ensure full functionality and to clear the warning light.
