Airbag control unit with part number 95910-0Y000

What is the function of the airbag control unit 95910-0Y000?

The airbag control unit with part number 95910-0Y000 is the central control module for the passive safety system in the Hyundai Santro AH2 (model years 2018–2022). It analyzes data from crash sensors in real time and determines whether to deploy airbags and seatbelt pretensioners, thereby protecting occupants during a collision.

As the “brain” of the restraint system, it processes signals from acceleration and angular velocity sensors. Based on this information, it precisely and rapidly triggers the ignition of the corresponding pyrotechnic charges in the airbags and seatbelt pretensioners.

An additional core function is event data recording. In the event of a crash, all relevant information—such as impact severity and activated components—is permanently stored in the device’s internal memory. This capability is crucial for accident analysis but also results in the control unit becoming locked after a collision.

Why does the control unit 95910-0Y000 fail?

The most common reason for repairing the 95910-0Y000 control unit is the storage of crash data following an accident, which leads to the unit being locked. Additionally, electronic faults can occur in hardware components such as capacitors or microcontrollers, caused by aging, moisture, or vibration.

After a collision—even one with low impact energy—the control unit stores a so‑called “crash entry” in its internal EEPROM memory. This lockout is a manufacturer‑imposed safety measure that prevents reuse without professional diagnostics. The airbag warning light remains illuminated until the data is cleared by a specialist.

Besides crash‑data locking, conventional hardware failures may also arise. Vibrations during vehicle operation and thermal cycling put stress on solder joints and components. Aging capacitors or malfunctions in the microcontroller, in particular, can lead to total failure or sporadic malfunctions of the control unit.

In practice, equivalent part numbers 95910-0Y001, 95910-0Y002, 285001003, and 5WK49251 are also affected and may be used in the Hyundai Santro AH2. These variants exhibit identical fault patterns and can be repaired in the same manner.

How do you recognize a defect in the 95910-0Y000?

A defect in the 95910-0Y000 control unit almost always manifests as a continuously illuminated or flashing airbag warning light on the instrument cluster. Often, the error code stored in the fault memory—indicating either an internal control unit fault or saved crash data—cannot be cleared using standard diagnostic equipment.

The most noticeable symptom is the active airbag warning light (SRS light). Unlike usual, it does not extinguish after starting the vehicle, signaling a malfunction in the safety system. This means that, in the event of a crash, the airbags might fail to deploy.

During workshop diagnostics, error codes indicating a problem with the control unit itself are read out. Typical messages include “Internal Control Unit Error” or “Crash Data Stored.” These errors are permanent and cannot be resolved without repairing the unit.

In rarer cases, complete communication failure may occur, rendering the control unit unresponsive via the OBD interface. In such situations, the diagnostic tool cannot establish a connection to the airbag system.

In which vehicles is the 95910-0Y000 control unit installed?

The airbag control unit with part number 95910-0Y000 is specifically designed for the second-generation Hyundai Santro (model code AH2), produced between 2018 and 2022. Airbag24 offers targeted repairs for this control unit, restoring safety to this vehicle model.

The primary and verified application for this component is the Hyundai Santro AH2 (model years 2018–2022).

Since equivalent part numbers 95910-0Y001, 95910-0Y002, 285001003, and 5WK49251 may also be installed in the same vehicle, it is important to verify the number stamped on the housing. At Airbag24, all these variants for the Hyundai Santro are professionally refurbished.

How is the 95910-0Y000 professionally repaired?

At Airbag24, the 95910-0Y000 control unit undergoes a standardized repair process. This begins with an incoming inspection, followed by professional clearing of crash data using specialized programming tools. For hardware defects, faulty components on the circuit board are replaced, and finally, full functionality is verified.

Once the removed control unit arrives at Airbag24, technicians perform a detailed analysis. They read out the internal fault memory to determine whether the issue stems from stored crash data or an electronic fault.

The core of the repair often involves the so‑called “crash reset.” Using specialized tools, direct access is gained to the memory chip (EEPROM) to erase accident‑related data. For electronic faults, defective components such as capacitors or controllers are precisely desoldered and replaced with new, high‑quality parts.

Subsequently, a comprehensive functional test is performed on a test bench to ensure that the control unit operates flawlessly and communicates without errors. Each repair comes with a 12‑month warranty.

What shipping options does Airbag24 offer?

To send your control unit for repair, you can either ship it to Airbag24 yourself at no cost or arrange a convenient UPS pickup from a location of your choice. For the return shipment, you have access to free standard UPS shipping, faster express options, and cash-on-delivery.

For sending your defective control unit, you have two choices: you can ship the package yourself or use UPS’s pickup service, which collects the package directly from your home or workshop.

After the repair is completed, the control unit will be securely repackaged and shipped back to you. Airbag24 offers several options for this: free standard UPS shipping, UPS express shipping, standard UPS shipping with cash-on-delivery, and express UPS shipping with cash-on-delivery. Alternatively, you can also pick up the repaired component in person at our facility.
