What is a Dacia SupeRNova I airbag control unit?
The Dacia SupeRNova I airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the correct and timely deployment of the driver and front passenger airbags in the vehicle.
This control unit continuously analyzes signals from acceleration sensors to precisely detect the severity and type of impact. In an emergency, it initiates airbag deployment within milliseconds to provide optimal occupant protection. The control unit also performs regular self-tests to ensure system integrity and report malfunctions.
Why is the Dacia SupeRNova I airbag control unit defective?
The Dacia SupeRNova I airbag control unit often malfunctions because it stores crash history data after an accident or because of internal errors such as overvoltage damage. This can lead to communication problems, constantly illuminated airbag warning lights, or a complete system failure, compromising vehicle safety.
Typical causes of failure include internal electronic defects caused by aging or electrical spikes. A missing or disrupted communication flow to the diagnostic device or other vehicle modules also indicates damage. In these cases, airbag control unit repair is often essential.
A faulty control unit can also prevent communication with diagnostic tools, making troubleshooting more difficult. In many cases, professional diagnostics and repair are necessary to restore functionality and eliminate safety risks.
Common error codes for Dacia SupeRNova I airbag control unit repair
During Dacia SupeRNova I airbag control unit repairs, specific error codes often occur, indicating internal defects or communication problems within the control unit. These codes signal that the central airbag unit itself is malfunctioning, and a precise diagnosis is necessary to restore safety.
- B1000 → Control unit communication error → Cause: Missing or disrupted communication between diagnostic device and airbag ECU, often defective control unit or power supply problems.
- 65535 → Control unit defective / internal error → Cause: Internal defect in the airbag control unit, common in various vehicle brands for internal control unit errors.
- 93F9 → Internal error in the airbag control unit → Cause: Internal error, often caused by overvoltage in the control unit or damaged components.
- B1002 → Communication error with airbag ECU (bus error) → Cause: Problems with data transmission via the vehicle bus, may indicate a defective control unit or wiring problems.
What part numbers are available for the Dacia SupeRNova I airbag control unit repair?
A 100% serial number-verified OEM part number for the Dacia SupeRNova I airbag control unit is not clearly documented publicly, making it difficult to source accurate replacement parts. However, related OEM numbers such as Autoliv 95640 and Continental 95160 can be used as a reference for airbag control unit repairs.
Research shows that Dacia-specific airbag control units often come from Autoliv or Continental, with the numbers listed for Dacia Logan or Duster serving as a general guide. For accurate identification, it is recommended to read the part number directly from the unit. Alternatively, official Dacia/Renault parts catalogs or a professional workshop can help validate the correct part number for the Dacia SupeRNova I airbag control unit repair.
Accurately determining the correct part number is essential to avoid failure of the new or repaired part. If unsure, always contact the manufacturer's customer support or a specialized workshop with access to OEM databases.
