Airbag control unit with part number 95910-0X100

What is the function of the airbag control unit 95910-0X100?

The airbag control unit with part number 95910-0X100 is the central control module for the occupant protection system (SRS) in various Hyundai compact cars. It continuously analyzes data from crash sensors and is responsible for precisely deploying airbags and seatbelt pretensioners at the right moment to protect occupants in the event of a collision.

As an SRS module (Supplemental Restraint System), this control unit serves as the brain of the passive safety system. It communicates via the CAN bus with other vehicle control units to obtain relevant vehicle data such as speed and deceleration, and to report the system status to the instrument cluster.

Its primary task is to interpret signals from the vehicle’s acceleration sensors. When predefined thresholds indicating a collision are exceeded, the control unit sends ignition pulses to the corresponding pyrotechnic initiators of the airbags and seatbelt pretensioners.

In addition, the 95910-0X100 control unit performs continuous self-tests. It monitors all connected components of the restraint system, including sensors, ignition circuits, and internal electronics. Any detected fault is stored in the fault memory and indicated by the illumination of the airbag warning light.

Why does the 95910-0X100 control unit fail?

The most common cause of malfunction in the 95910-0X100 control unit is the storage of crash data in its internal EEPROM after a collision. Additionally, internal electronic defects in components such as capacitors, resistors, or memory chips, as well as corrosion at connector contacts, can also lead to failure.

Following a collision—even minor accidents where the airbags did not deploy—the control unit stores so‑called “crash data” or “event data.” For safety reasons, these data lock the module out of further operation, which manifests as a permanently illuminated airbag warning light. This condition cannot be cleared using conventional diagnostic equipment.

Another cause of failure is age‑related or externally induced damage to electronic components on the circuit board. Moisture can cause corrosion on connection pins, while voltage fluctuations in the vehicle’s electrical system may damage components such as fuses, MOSFETs, or even the memory chips themselves.

A visual inspection by a technician can often reveal initial clues, such as water damage or mechanical damage to the housing. However, determining the exact cause requires a thorough electronic analysis of the circuit board and reading the internal memory using specialized tools.

How do you recognize a defect in the 95910-0X100?

A defective 95910-0X100 airbag control unit primarily manifests as a permanently lit or intermittently flashing airbag warning light on the instrument cluster. Furthermore, the fault memory often cannot be cleared, and the control unit reports internal error codes or stored crash data indicating a blockage.

The clearest sign is the active airbag check lamp (SRS light) upon engine start-up. The system thereby indicates that it has detected a fault and may not function correctly in the event of a collision.

If a workshop attempts to clear the fault memory with a standard OBD diagnostic tool, the error message often returns immediately. Frequently, error codes are displayed indicating an “internal control unit fault” or “crash event stored,” necessitating external repair.

Even after disconnecting the vehicle battery and performing a reset, the fault persists. This strongly suggests that the root cause is not temporary but permanently lodged in the control unit’s memory or stems from a hardware defect.

In which vehicles is the 95910-0X100 control unit installed?

The airbag control unit with part number 95910-0X100 is primarily used in various Hyundai compact cars. This includes, in particular, the i10, Grand i10, and Xcent models across multiple generations and model years. At Airbag24, we repair this specific module for all affected vehicles.

Specifically, this control unit can be found in the following Hyundai models and series:

Hyundai i10: Affected are the first generation (PA, model years 2008–2010) as well as its facelifted version (PA Facelift, 2011–2013). The second generation (IA, 2013–2016) and its associated facelift (IA Facelift, 2017–2019) also utilize this module.

Hyundai Grand i10: The BA-series model is likewise equipped with the 95910-0X100 control unit.

Hyundai Xcent: This control unit is also listed for the Xcent sedan variant of the BA series (2014–2022).

How is the 95910-0X100 control unit professionally repaired?

At Airbag24, the 95910-0X100 control unit is repaired according to a standardized process. Following an initial inspection, stored crash data is erased from the EEPROM, and the electronics are examined for defective components. After refurbishment, the module is tested on a test bench to ensure full functionality.

Upon sending the removed control unit to Airbag24, a comprehensive fault diagnosis is first performed. Technicians read the internal fault memory to identify the exact cause—whether it’s crash data or an electronic defect.

The core of the repair involves erasing the crash data stored in the EEPROM or flash memory using specialized programming tools (reset). Simultaneously, a visual inspection and electronic analysis of the circuit board are carried out to detect damaged SMD components, fuses, or capacitors, which are replaced if necessary.

Finally, each repaired control unit undergoes a rigorous functional test. This simulates proper communication via the CAN bus and verifies the flawless operation of the internal circuits. Only after passing this test is the device approved for return shipment, including 2 years' statutory liability for defects on the repair performed.
