Airbag control unit with part number 8200769222

What is the function of the airbag control unit 8200769222?

The airbag control unit with part number 8200769222, also known as the SRS module, is the central control unit for the occupant protection system in various Dacia models. It processes data from crash sensors and, in the event of a collision, deploys the airbags and pretensioners to protect occupants.

As the brain of the passive safety system, this module continuously monitors and evaluates signals from acceleration and pressure sensors in the vehicle. If the system detects a collision severe enough to warrant activation of the restraint systems, it sends the appropriate ignition commands to the airbag modules and seatbelt pretensioners within milliseconds.

The control unit is manufactured by TEMIC and is also known under the alternative manufacturer’s part number 2840096301300. For proper operation in the vehicle, it is crucial that the installed part number exactly matches the original component to ensure compatibility with vehicle-specific sensors and actuators.

What defects occur in the control unit 8200769222?

The most common cause of failure for the control unit 8200769222 is the storage of crash data after an accident, which results in irreversible locking of the module. In addition, internal hardware defects in electronic components or errors in the internal memory can lead to malfunctions or total failure.

Even after a minor collision where the airbags did not deploy, the control unit stores what is known as a “crash event.” This information locks the module for safety reasons, preventing further use. Repair aims to safely erase this data and restore full functionality.

Internal faults can also be the cause—these involve hardware defects on the control unit’s circuit board. A professional repair addresses these issues, ensuring that, once restored, the control unit performs like a new component and reliably controls the airbag system.

How do you recognize a defect in the control unit 8200769222?

A defect in the airbag control unit 8200769222 typically manifests as a permanently illuminated airbag warning light (SRS light) in the instrument cluster. Often, the control unit can no longer be accessed by a diagnostic tool, or specific fault codes are stored indicating an internal malfunction.

The clearest symptom is the active airbag warning light, signaling to the driver that the passive safety system is either non-functional or only partially operational and may fail to deploy correctly in the event of a crash.

Another clear indication is when the workshop cannot establish communication with the airbag control unit via the OBD port—the module does not respond to diagnostic requests. Alternatively, the diagnosis may display a fault code such as “internal control unit defect” or “crash data stored,” directly pointing to the need for repair or replacement.

In which vehicles is the control unit 8200769222 installed?

The airbag control unit 8200769222 is primarily used in various Dacia vehicles. Its compatibility spans multiple model series and production years, notably including the Logan and Sandero lines, as well as the Dacia Solenza. Repair is available for all these models.

How does the repair of the control unit 8200769222 proceed?

At Airbag24, the control unit 8200769222 undergoes a professional repair process. Upon submission, a thorough fault analysis is performed. Crash data is then erased, and defective components are replaced if necessary. A final quality and functional test ensures that the module operates like new again.

After removal from the vehicle, the control unit is sent to Airbag24. Our technicians conduct an incoming inspection to verify reported faults. The core of the repair involves safely erasing stored crash data and repairing any hardware defects on the circuit board.

Subsequently, the control unit undergoes a comprehensive functional test, ensuring that all safety‑critical functions have been fully restored. Following successful testing, the module is ready for immediate use and can be installed in the vehicle via plug-and-play. We provide 2 years' statutory liability for defects on every repair.
