Airbag control unit with part number 95910-K2500

What is the function of the airbag control unit 95910-K2500?

The airbag control unit with part number 95910-K2500 is the central safety module (SRS module) for the Hyundai Venue QX from model year 2019 onwards. Its primary task is to monitor crash sensors, process their data, and precisely activate restraint systems such as front, side, and head airbags, as well as seatbelt pretensioners in the event of a collision.

As a safety-critical component, it serves as the brain of the vehicle’s passive safety system. It performs a self-diagnosis every time the vehicle is started, ensuring that all connected components—from airbags to sensors—are functioning properly.

Any malfunction in this system is immediately signaled to the driver by the illumination of the airbag warning light on the instrument panel. Therefore, proper operation of this control unit is essential for occupant safety.

Why does the control unit 95910-K2500 fail?

The most common cause of failure for the control unit 95910-K2500 is the storage of crash data (so‑called hardcode) after an accident, often resulting in error code B1620. Other causes include internal hardware defects, electrical overloads due to voltage spikes, or communication errors on the module’s circuit board.

After an airbag deployment, accident data is permanently stored in the device’s memory. This lockout is a manufacturer‑imposed safety feature that prevents the system from being easily reset without professional diagnostics. Error code B1620 directly indicates this condition.

In addition to crash data, purely electronic faults can also occur. Voltage spikes in the vehicle’s electrical system may damage sensitive components on the circuit board. An internal communication error—often indicated by error code B1000—suggests a hardware defect within the control unit itself, rather than a problem with the vehicle’s wiring.

It’s important to note that these fault patterns can also appear in alternative and interchangeable part numbers such as 95910-K2100, K2959-10100, and 95512, as they are technically closely related to 95910-K2500.

How do you recognize a defect in the 95910-K2500?

A defect in the airbag control unit 95910-K2500 primarily manifests as a continuously illuminated or flashing airbag warning light on the dashboard. Another clear indication is when the control unit becomes unresponsive via the OBD port, preventing diagnostic tools from establishing communication.

The airbag warning light is the driver’s primary alert signal. If it remains lit continuously after engine start-up, the system is signaling a serious stored fault that compromises the functionality of the entire restraint system.

A complete loss of communication is another typical symptom. In such cases, the workshop cannot read or clear error codes because the module no longer responds to diagnostic requests, pointing to a severe internal hardware failure.

If diagnostics are still possible, specific error codes such as B1620 (crash data stored) or B1000 (control unit communication error) provide definitive evidence of a defect requiring professional repair.

In which vehicles is the control unit 95910-K2500 installed?

The airbag control unit with part number 95910-K2500 was specifically developed for Hyundai vehicles. At Airbag24, we specialize in repairing this module, which is predominantly used in the Hyundai Venue QX series starting from the 2019 model year.

At Airbag24, we repair the 95910-K2500 control unit for the following model:

Hyundai Venue (QX series, from model year 2019)

Our repair service also covers technically related and interchangeable part numbers such as 95910-K2100, K2959-10100, and 95512, which may also be installed in this vehicle model.

How is the 95910-K2500 professionally repaired?

A professional repair of the 95910-K2500 control unit is a multi‑step process that begins with precise diagnostics. The core of the restoration involves erasing stored crash data and, if necessary, replacing defective electronic components. A final functional test ensures full operational capability.

After being sent to Airbag24, the control unit undergoes a standardized repair process designed to guarantee the highest quality and safety.

First, an incoming inspection is performed, during which the fault memory is read to verify codes such as B1620. Next, crash data is removed directly from the memory chip using specialized equipment. If hardware repair is required, faulty components on the circuit board are replaced by qualified technicians.

After successful repair, the module is calibrated and subjected to a comprehensive functional test to ensure it communicates flawlessly and is fully operational again. We provide 2 years' statutory liability for defects on every repair.
