Airbag control unit with part number 95910-05700

What is the function of the airbag control unit 95910-05700?

The control unit 95910-05700 is the central control module of the occupant safety system (SRS) in Hyundai Atos models. It continuously analyzes data from crash and acceleration sensors, seatbelt pretensioners, and seat occupancy sensors to precisely deploy airbags and activate seatbelt pretensioners within milliseconds in the event of a collision.

As the brain of the safety system, this component makes the critical decision about when and which restraint systems need to be activated. It processes incoming signals to ensure the protection of vehicle occupants.

Following a crash, accident data—known as crash data—is permanently stored in the control unit’s internal memory. This causes the airbag warning light to remain illuminated, and the system remains locked for safety reasons until a professional repair or reset is performed.

Why does the control unit 95910-05700 fail?

The most common reason for repairing the control unit 95910-05700 is the storage of crash data after an accident, which locks the system. Other causes include internal electronic faults, such as faulty power supplies, defective memory chips, or damaged solder joints on the circuit board.

The by far most frequent cause of failure is a crash record stored in memory. Even if all airbags and seatbelt pretensioners have been replaced, the control unit remains internally locked and displays an error until the data is professionally erased.

In addition, defects in the internal electronics can occur. These include age-related failures of components such as capacitors, voltage regulator ICs, or the memory chip itself. Cold solder joints or corrosion at connector contacts due to moisture can also lead to malfunctions.

In rarer cases, damaged wiring or connectors within the vehicle are the root cause. A professional diagnosis therefore also examines the area surrounding the control unit to rule out external sources of failure.

How do you recognize a defect in the control unit 95910-05700?

The main symptom of a defect in the control unit 95910-05700 is the airbag warning light that remains constantly illuminated on the instrument panel. Often, communication with the control unit via a diagnostic tool is no longer possible, or specific internal error codes such as “component defective” are stored.

The most obvious sign is the airbag warning lamp staying lit even with the engine running. This indicates a malfunction in the safety system that should be checked immediately.

Another clear indication is when a diagnostic tester cannot establish a connection to the airbag control unit. The device fails to respond to queries, suggesting a complete breakdown of the communication electronics.

The fault memory may contain entries such as “control unit defective” or “crash data stored.” These directly point to an internal fault in the control unit requiring repair.

In which vehicles is the control unit 95910-05700 installed?

The airbag control unit 95910-05700 is specifically designed for certain compact car models from Hyundai. Airbag24 offers professional repair services for the Hyundai Atos MX and Hyundai Atos Prime MX models, where this control unit was factory-installed.

At Airbag24, the control unit with part number 95910-05700 is refurbished for the following vehicle models:

Hyundai: Atos MX (1997–2002), Atos Prime MX (2004–2008)

How does the repair process work at Airbag24?

The repair process at Airbag24 begins with the proper removal and shipping of the control unit. Following a detailed analysis of the hardware and memory, crash data is erased or internal electronic faults are rectified. Each repair is thoroughly tested and comes with 2 years' statutory liability for defects.

First, the vehicle’s fault memory should be read out to narrow down the cause of the problem. Then, with the battery disconnected, the control unit is carefully removed—it is often located near the center console or under the vehicle floor.

After sending the unit to Airbag24, technicians perform an initial inspection. During this step, the circuit board is exposed and examined to determine whether only crash data needs to be erased or if there is a hardware defect affecting electronic components.

The actual repair involves selectively erasing crash records stored in memory (EEPROM/Flash) using specialized programming tools. For hardware defects, faulty components such as voltage regulators or capacitors are replaced, and solder joints are reworked.

Once the repair is successfully completed and final functionality has been verified, the housing is professionally sealed again. Airbag24 provides 2 years' statutory liability for defects on every repaired unit.
