Airbag control unit with part number 95910-2S750

What is the function of the airbag control unit 95910-2S750?

The airbag control unit 95910-2S750 is the central safety module (SRS module) in vehicles such as the Hyundai Tucson NX4. It continuously monitors the sensors of the restraint system, processes their data, and, in the event of a crash, precisely deploys airbags and pretensioners. After a collision, it stores relevant crash data, which results in the system being locked.

The primary task of this control unit is to ensure passive safety. It receives signals from acceleration and yaw rate sensors to assess the severity and nature of an impact. Based on this analysis, the module decides within milliseconds which safety devices need to be activated to provide optimal protection for occupants.

A key feature of the 95910-2S750 is its ability to store crash data. Once an airbag has been deployed, this data is permanently saved in the module’s internal memory. While this process aids in post-crash analysis, it also locks the control unit for further operation and activates the airbag warning light.

Why does the control unit 95910-2S750 fail?

The most common cause of failure for the 95910-2S750 is the storage of crash data after a collision. This permanent data retention locks the module and prevents its reuse. Other causes include internal electronic malfunctions, communication failures, or moisture damage that leads to operational issues.

After an airbag deployment, a so‑called “crash lock” is set in the control unit’s memory. This lock cannot be cleared using standard diagnostic tools, requiring professional repair to reactivate the module. Without this intervention, the airbag warning light remains illuminated.

In addition to crash data, internal component defects can also be responsible. These often manifest as a lack of communication with the diagnostic tool or specific internal error codes such as B1206. Pre-existing damage caused by moisture or improper repair attempts can also permanently harm the sensitive electronics.

It is important to verify the exact part number, as similar control units like 95910-4H380 or 95910-1X000 are designed for other vehicle models and are not interchangeable. Confusion could lead to compatibility issues.

How do you recognize a defect in the 95910-2S750?

A defect in the airbag control unit 95910-2S750 primarily shows up as the airbag warning light constantly illuminated on the instrument panel. Often, the light stays on after starting the engine or only turns on after about 30 seconds. Another clear indication is the absence of communication with the control unit via the OBD port.

The most obvious symptom is the persistently lit airbag indicator light. It signals a fault in the restraint system, which in most cases points directly to the control unit—especially following a crash.

Another typical sign is when a workshop using a diagnostic tool cannot establish a connection to the airbag control unit. The module fails to respond to requests, preventing accurate fault diagnosis and often indicating an internal malfunction.

The fault memory may contain specific error codes that point directly to the control unit itself. Errors such as “Internal Control Unit Fault” or code B1206 clearly indicate a problem within the SRS module that can typically be resolved through repair.

In which vehicles is the 95910-2S750 installed?

The airbag control unit with part number 95910-2S750 is specifically designed for Hyundai models. At Airbag24, we repair this control unit for the fourth-generation Hyundai Tucson (NX4) as well as its facelift model, restoring full functionality of the safety system at an affordable cost.

At Airbag24, the 95910-2S750 control unit is refurbished for the following models:

Hyundai:

Tucson NX4 (model years 2020–2023)

Tucson NX4 Facelift (from model year 2023 onward)

How is the 95910-2S750 control unit professionally repaired?

Repair at Airbag24 focuses on the electronic restoration of the 95910-2S750 control unit. Following a thorough initial inspection, stored crash data is removed using specialized software. A final functional test then ensures proper operation. We offer a 12-month warranty on every repair.

Upon receipt of the control unit at Airbag24, a detailed diagnosis is first performed. During this process, the fault memory is read out to determine whether the root cause is indeed stored crash data or another electronic defect.

The core of the repair is erasing the crash data. This process restores the module to its factory settings, deactivates the airbag warning light, and reactivates the entire restraint system. Since only the internal data is erased, no re‑coding or programming on the vehicle is required after installation.

If further defects, such as damaged components, are detected during the initial inspection, this will be communicated transparently. Upon completion of all work, the control unit undergoes a comprehensive functional test to ensure it is fully operational again.

Is repairing 95910-2S750 worthwhile?

Yes, repairing 95910-2S750 is an economically and environmentally sound alternative to purchasing a new unit. You often save over 80% compared to a new part, which frequently costs more than €500. Moreover, the repair is sustainable and requires no additional programming after installation, saving both time and further expenses.

The greatest advantage is the cost savings. While a new control unit entails substantial expenses, the repair—by erasing the crash data—is significantly cheaper. You receive a fully functional original part that fits your vehicle perfectly.

An additional benefit is the plug-and-play nature of the repaired unit. Since the original vehicle configuration is preserved and only the crash data is removed, the control unit can be easily reinstalled without the need for costly and time‑consuming re‑coding at a specialized workshop.

The repair also represents an eco‑friendly solution. Instead of discarding a fully functional component, it is reused, conserving valuable resources and reducing electronic waste. With a 12‑month warranty on the completed repair, you take no risks.

What shipping options are available?
