What is a Dacia 1310 Break I airbag control unit?
The Dacia 1310 Break I airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It precisely monitors signals from acceleration sensors, stores relevant crash data, and ensures the proper, millisecond-accurate deployment of all airbag modules and seatbelt pretensioners in the vehicle to maximize occupant safety.
This crucial component was developed specifically for the Dacia 1310 Break I, primarily in the 1990s and early 2000s. It integrates into the 12V electrical system and processes signals from various sensors.
Its primary function is to analyze data in the event of a collision and, if necessary, safely deploy the airbags. This effectively protects vehicle occupants from serious injuries.
Once triggered, the module stores important information for diagnostic purposes and accident reconstruction. This is also relevant for Dacia 1310 Break I airbag control unit repairs.
Why is the Dacia 1310 Break I airbag control unit defective?
The Dacia 1310 Break I airbag control unit often fails due to age, corrosion, or internal electrical faults affecting the sensitive electronics. This leads to safety system failure and requires immediate repair. A defective control unit poses a significant risk to occupant safety.
Typical causes of failure include moisture damage, which causes corrosion on the contacts or circuit board. Overvoltages in the vehicle electrical system can also damage internal components.
Wear on the solder joints or a defective capacitor are other reasons why the control unit may no longer function properly. A precise diagnosis is essential for any repair.
A defective control unit is often indicated by an illuminated airbag warning light on the dashboard. This is a clear sign that a service visit to the workshop is necessary.
Common error codes for Dacia 1310 Break I airbag control unit repair
For Dacia 1310 Break I airbag control unit repairs, specific error codes are often generic due to the lack of OEM data. However, typical B-codes indicate ECU communication problems, internal malfunctions, or interruptions in the airbag loops. These codes help diagnose a defective system.
Since no exact OEM error codes are publicly available for the Dacia 1310 Break I airbag control unit, diagnostics are based on general OBD standards.
These codes are valid across all manufacturers and provide initial guidance for troubleshooting.
- B1000: Control unit communication error → Indicates problems with data transmission within the airbag system or with other vehicle components.
- B0071: Supplemental Deployment Loop #1 Resistance Low → Indicates a low resistance in the airbag deployment circuit, possibly due to a short circuit.
- B0074: Supplemental Deployment Loop #1 Open → Indicates an open circuit in the airbag deployment circuit, preventing deployment.
- B0075: Supplemental Deployment Loop #1 Short to Ground → Indicates a short circuit of the airbag deployment circuit to vehicle ground.
- B1171: Internal SDM (control unit) Failure → Indicates an internal defect in the airbag control unit itself that requires repair or replacement.
- B1310: Ambient Air Temperature Sensor Failure → May indicate a fault in the temperature sensor, which is often integrated into the airbag control unit.
- B1312: High Side Temp Sensor Open Circuit → Indicates an open circuit in the high side temperature sensor, which is critical to the operation of the control module.
Precise troubleshooting requires access to vehicle-specific diagnostic tools. This is often essential for a successful Dacia 1310 Break I airbag control unit repair.
What part numbers are available for the Dacia 1310 Break I airbag control unit repair?
For Dacia 1310 Break I airbag control unit repairs, no exact, 100% verified OEM part numbers are available in common databases. The age of the model and the limited availability of national catalogs make part identification significantly more difficult, requiring alternative methods for the workshop.
Despite intensive research in professional spare parts databases such as TecDoc and manufacturer catalogs from Bosch, Continental, or Autoliv, there were no matches.
This is typical for older vehicles, whose airbag systems are less standardized and digitally recorded. Specialized workshops or national Dacia catalogs may provide clues.
For reliable identification, we recommend contacting Dacia or Renault dealers directly. They may have access to original parts catalogs.
Specialized airbag repair shops that repair Dacia 1310 airbag control units can often find reference numbers based on the installed part. Using the VIN is another option.
The Dacia 1310 Break I airbag control unit repair often requires an individual inspection of the installed control unit in order to determine the correct variant.
