What is a Renault Safrane II airbag control unit?
The Renault Safrane II airbag control unit is the central safety unit in your vehicle, continuously monitoring sensors and precisely controlling the deployment of all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It stores important crash data and ensures the correct functioning of the entire passive safety system, essential for your safety.
This microprocessor-based module is programmed for fast and reliable detection of impact patterns.
It continuously monitors the signals from crash sensors and makes the decision about airbag deployment in milliseconds.
Why is the Renault Safrane II airbag control unit defective?
A Renault Safrane II airbag control unit may be defective because it stores crash data after an accident that requires a reset, or due to internal electronic errors caused by aging, voltage spikes, or moisture. A failure can impair the functionality of the airbag systems and activate the warning light.
After a crash, the control unit stores accident-relevant data, which blocks its further use until this data is deleted.
Communication problems with other vehicle systems or wiring errors can also signal a failure of the airbag control unit.
Sometimes internal hardware defects make a Renault Safrane II airbag control unit repair or replacement necessary.
Common error codes for Renault Safrane II airbag control unit repair
During Renault Safrane II airbag control unit repair, specific error codes indicate problems that require targeted diagnostics to identify the cause of the failure. These codes often signal internal module defects or stored crash events that require professional repair.
The error codes are exclusively control unit-related and can be read out via a diagnostic interface.
Certain codes require specialized reset services because they cannot be cleared with simple OBD scanners.
- B1015 → Airbag module faulty → Internal defect in the airbag control unit
- B1139 → SRS module error → Airbag control unit general system error
- B1193 → Airbag control unit related error → Non-specific error in the airbag control unit
- B1206 → Airbag RCM (Restraints Control Module) Error → Restraint system control error
- B1342 → SRS system error → Comprehensive failure in the Supplemental Restraint System
- B1620 → SRS Error → General error in the airbag system
- B1649 → Crash detected → Accident event data stored in memory
For an accurate diagnosis and repair of the Renault Safrane II airbag control unit error codes, the use of a manufacturer-specific diagnostic tool is advisable.
