Airbag control unit with part number 95910-2Y200

What is the function of the airbag control unit 95910-2Y200?

The airbag control unit with part number 95910-2Y200 is the central control unit (SRS ECU) for the occupant protection system in the Hyundai ix35 LM. It processes data from crash sensors and, in the event of a collision, determines whether and which airbags or seatbelt pretensioners need to be deployed to protect the occupants.

The part number 95910-2Y200 is an original equipment manufacturer (OEM) replacement part specifically designed for the Hyundai ix35 LM model series. Its primary task is the continuous monitoring of all safety‑related components of the restraint system.

The control unit communicates continuously with various sensors in the vehicle, such as the acceleration sensors located at the front and on the sides. Upon a collision, it analyzes incoming signals within milliseconds and activates the necessary restraint devices.

Why does the control unit 95910-2Y200 fail?

The most common cause of failure for the control unit 95910-2Y200 is the storage of crash data after an accident. This data locks the device’s functionality as a safety precaution. Other causes include internal hardware defects in electronic components like capacitors or memory chips, which can lead to communication failures.

After an accident in which airbags or seatbelt pretensioners have been deployed, the control unit writes a permanent data record into its internal memory. This so‑called “crash lock” prevents reuse without professional repair and ensures that the airbag warning light remains illuminated.

In addition to accident‑induced locks, age‑related defects in individual electronic components may also occur. These often result in complete loss of communication, leaving diagnostic tools unable to access the control unit.

It is important to note that there are variants and related part numbers installed in similar models that exhibit comparable fault patterns. These include numbers 95910-2Y100, 95910-2S100, 95910-2S750, and 95910-2Y300. Therefore, carefully verifying the exact part number installed in your vehicle is essential.

How do you recognize a defect in the 95910-2Y200?

A defect in the airbag control unit 95910-2Y200 primarily manifests as the airbag warning light remaining constantly illuminated on the instrument cluster. Often, communication with the control unit via a diagnostic tool is also no longer possible. The fault memory may also contain error codes associated with specific airbags or crash sensors.

The clearest indication is the airbag warning light (SRS light), which fails to turn off after starting the engine or stays lit continuously. This signals a malfunction in the safety system and means that the airbags will not deploy in the event of a collision.

Workshops frequently find that the control unit is no longer responsive. Attempts to read the fault memory fail because the diagnostic tool cannot establish a connection to the module.

In some cases, specific error codes are stored that point to an internal defect within the control unit itself or mistakenly report individual components—such as seat airbags or crash sensors—as faulty, even though the root cause lies in the control unit. In this condition, the vehicle is often unsafe to drive.

In which vehicles is 95910-2Y200 installed?

The airbag control unit with part number 95910-2Y200 is specifically designed for Hyundai models. It is mainly used in the Hyundai ix35 SUV of the LM series, both in pre‑facelift and facelift versions.

At Airbag24, we professionally repair part number 95910-2Y200 and its variants for the following specific vehicle models:

Hyundai:

- Hyundai ix35 (LM series, model years 2009–2013)

- Hyundai ix35 (LM series, facelift model years 2013–2015)

Since multiple variants exist, it is essential to verify the part number directly on the removed control unit before shipping it for repair to ensure compatibility.

How does the repair of the 95910-2Y200 proceed at Airbag24?

Repair at Airbag24 includes professional diagnosis of the submitted control unit, elimination of the root cause at the component level, and a final functional test. Stored crash data is securely erased, and defective components are replaced to restore full functionality. You receive 2 years' statutory liability for defects on the repair.

First, the defective control unit is removed from the vehicle by the customer or a workshop. It is typically located beneath the center console or dashboard.

Upon submission to Airbag24, our technicians perform an initial inspection using state‑of‑the‑art diagnostic equipment to identify the exact cause of the fault. This may involve analyzing internal memory or testing individual electronic components.

The actual repair focuses on troubleshooting. This includes clearing crash data or replacing defective hardware components. It is a chip-level refurbishment, offering a cost-effective alternative to an expensive new part.

Following successful repair, the control unit undergoes a comprehensive functional test. It is then securely packaged and shipped back to the customer. After reinstallation in the vehicle, the airbag warning light should be off.
