Airbag control unit with part number 8200962347

What is the function of the airbag control unit 8200962347?

The airbag control unit with Renault part number 8200962347 is a central safety module manufactured by Autoliv. It continuously monitors all components of the occupant restraint system, processes data from crash sensors, and ensures that, in the event of an accident, airbags and seatbelt pretensioners are deployed precisely and within milliseconds.

Technically, this control unit is often also identified by the Autoliv reference number 610796100. Its primary task is to process acceleration and collision data to determine the type and severity of an impact.

Based on this analysis, the control unit decides which restraint devices—such as front airbags, side airbags, or seatbelt pretensioners—should be activated to provide optimal protection for occupants.

Its typical installation location is centrally positioned in the vehicle floor, often beneath the center console. This placement is critical, as secure mounting to the vehicle body ensures accurate detection of crash forces, enabling precise deployment.

Why does control unit 8200962347 fail?

The most common cause of failure for control unit 8200962347 is the storage of crash data after an accident. This data permanently locks the system and cannot be cleared through standard workshop diagnostics. Another frequent reason is internal electronic faults, which result in specific error codes such as B1620 or B1650, indicating issues with the internal memory (EEPROM) or power supply.

Following a collision, the control unit writes a so‑called “crash record” into its non-volatile memory. This is a safety feature that triggers a full system check. The record blocks the control unit’s functionality and causes the airbag warning light to remain illuminated permanently.

Internal hardware defects are also a common cause. These include circuit board failures, defective memory chips (EEPROM/Flash), faulty voltage regulators, or cold solder joints caused by vibration. Such defects often manifest as complete system failure or loss of communication.

In particular, for the Renault Maxity I, error codes B1620 (control unit circuit fault) and B1650 (EEPROM/memory issue) are typical indicators of these internal electronic malfunctions. In rarer cases, the vehicle identification number (VIN) stored in the control unit may also become corrupted.

Technically, control units with part numbers 8200962363, 8201043701, 610796000, or 611131000A are often identical in design or software-compatible, suggesting a shared technical platform. In most cases, repair represents a cost-effective alternative to replacing the unit with a new one.

How do you recognize a defect in control unit 8200962347?

A defect in control unit 8200962347 almost always manifests as the airbag or SRS warning light remaining constantly illuminated on the instrument panel. Other typical symptoms include loss of communication with the diagnostic tester, error messages such as “Airbags defective” on the display, or a persistent entry in the fault memory stating “Component defective” or “Crash data stored,” which cannot be erased.

The most noticeable sign is the active airbag warning light. This light may illuminate immediately upon ignition or after a delay of about 30 seconds, then stay on continuously.

Another clear indication is when the workshop’s diagnostic tool cannot establish communication with the airbag control unit. The unit becomes unreachable on the CAN bus, even though other control units in the vehicle remain functional.

Often, other control units—such as the engine control unit—also reference an airbag system fault, for example, the unerasable entry “Crash data stored.” Likewise, a “Component defective” error directly logged in the airbag control unit is a clear red flag.

Depending on the vehicle model, plain-text messages may appear on the information display indicating an airbag malfunction, sometimes accompanied by a notification related to the fuel shut-off valve.

It is essential to understand that when the airbag warning light is on, the entire restraint system is disabled. This poses a significant safety risk and inevitably results in failure during the mandatory vehicle inspection. Using simulators or resistors is life‑threatening and will lead to revocation of the vehicle’s operating permit.

In which vehicles is control unit 8200962347 installed?

The Autoliv airbag control unit with part number 8200962347 is primarily used in various Renault models. Compatibility spans multiple vehicle platforms, making precise identification via the part number crucial. At Airbag24, we repair this control unit for a range of Renault vehicles.

At Airbag24, the control unit 8200962347 is repaired for the following Renault models, among others:

Renault Clio III and Renault Clio Van III

Renault Fluence I (model years 2009–2018)

Renault Latitude I (model years 2010–2015)

Renault Maxity I (model years 2007–2019)

Renault Modus I (model years 2004–2012)

Renault Trafic I (model years 1980–2001) and other Trafic generations with matching part numbers.

Exact compatibility should always be confirmed by verifying the part number 8200962347 or the reference number 610796100 printed on the control unit.

How is the repair of control unit 8200962347 carried out?

Professional repair begins with a vehicle diagnosis to rule out peripheral faults. After removal and shipment to Airbag24, an electronic analysis is performed. Crash data are erased, and defective components on the circuit board are replaced. Following successful refurbishment and final testing, the unit is returned ready for reinstallation.

Before removal, a thorough fault diagnosis in the workshop is essential. It must be ensured that the fault is not caused by external components such as seatbelt pretensioners, seat occupancy mats, or crash sensors. The readout protocol should be included with the unit when sending it in.

Removal must be conducted by trained specialists according to manufacturer guidelines, with particular attention to safety procedures for SRS systems, including disconnecting the battery and observing required waiting periods.

At Airbag24, the control unit is analyzed on a specialized test bench. Technicians directly read the internal memory (EEPROM/Flash) to erase stored crash data ("crash reset"). If additional hardware defects are present, faulty components such as ICs or memory chips are replaced with original or equivalent-quality parts.

After reinstalling the unit in the vehicle, the entire system’s fault memory must be cleared. The repaired control unit is returned with all vehicle data and is ready for use immediately after reinstallation — coding or programming is not necessary. We provide 2 years' statutory liability for defects on every repair.
