What is a Dacia 1310 III airbag control unit?
The Dacia 1310 III airbag control unit is the central safety unit in the vehicle, precisely deploying the airbags and seatbelt pretensioners in an emergency. It continuously monitors sensor data and stores important crash information, thus ensuring the functional safety of the occupant protection system in the event of a collision.
This electronic control unit, also called airbag ECU or SRS control unit, is responsible for the precise and time-critical activation of the safety systems.
It processes signals from acceleration and impact sensors, as well as seat belt pretensioner sensors, and initiates the ignition of the airbag modules. The control unit has a 12V power supply and internal fuses to protect against faults.
For diagnostic purposes, the device communicates via protocols such as K-Line or CAN bus and stores error codes and events in a non-volatile memory (EEPROM).
Why is the Dacia 1310 III airbag control unit defective?
A Dacia 1310 III airbag control unit often fails because it stores crash data after an accident that requires a reset, or due to internal electronic errors, overvoltages, and corrosion. Age-related component wear or software problems can also impair the function of the safety-relevant component, necessitating repair or replacement.
After an airbag is deployed, the control unit stores indelible crash data, which blocks it and makes a Dacia 1310 III airbag control unit repair or replacement unavoidable.
Other common causes of defects include internal component failures due to age or electrical problems, such as faulty solder joints or worn capacitors.
Overvoltages in the vehicle electrical system, moisture penetration or corrosion at the connections can also lead to a failure of the airbag ECU.
A defect in the control unit is usually indicated by the airbag warning light in the instrument cluster illuminating, which requires immediate diagnosis in a workshop.
Common error codes for Dacia 1310 III airbag control unit repair
During Dacia 1310 III airbag control unit repairs, generic B-codes often occur, indicating communication, power supply, or internal memory errors, as model-specific codes are rarely documented. These error codes help locate and resolve the cause of warning lights and airbag system malfunctions.
- B1000 → Control unit communication error → Error in the internal or external communication bus of the airbag control unit.
- B0003 → Driver front airbag deployment control stage 3 → Monitoring problem in the driver front airbag circuit.
- B1004 → Airbag control unit power supply error → Insufficient or unstable power supply to the control unit.
- B1010 → Internal memory error airbag control unit → Data corruption or defect in the internal data memory of the control unit.
- B1020 → Communication error between airbag control unit and engine control unit → Malfunction in the data transmission between airbag ECU and engine control unit.
These typical error codes are generally valid for airbag control units and provide a basis for troubleshooting your Dacia 1310 III.
Model-specific error codes for the Dacia 1310 III are not directly documented in the available search results and often require access to Renault/Dacia-specific service databases.
It is important to note that error codes for seat belt pretensioners or external sensors (e.g. side impact sensors) are excluded here, as the focus is on pure airbag control unit errors.
What part numbers are available for the Dacia 1310 III airbag control unit repair?
For the Dacia 1310 III airbag control unit repair, there are currently no 100% verified, exact OEM part numbers available from public sources, as this older model requires specific database access. These numbers can often be found through Renault parts catalogs or professional systems like TecDoc.
The Dacia 1310 III is an older model that was mainly sold in Eastern Europe, which makes the direct availability of OEM part numbers for the airbag control unit difficult.
The present search results do not contain specific OEM part numbers for the airbag control unit of this model, but refer to other control units or vehicle models such as the Dacia Logan or Renault Clio.
Although manufacturers such as Bosch, Continental, Siemens and Autoliv are traditional suppliers of airbag control units, exact type and part numbers must be requested via professional databases such as TecDoc or TecAlliance.
For reliable identification of the correct part number, it is recommended to consult official Renault/Dacia manufacturer catalogs, authorized parts dealers, or specialized auto parts professionals with access to OEM databases.
Providing the chassis number (VIN) of your Dacia 1310 III or the type number readable on the control unit can make the search for the exact part number for your Dacia 1310 III airbag control unit repair much more precise.
