Airbag control unit with part number 95910-3F300

What is the function of the airbag control unit 95910-3F300?

The airbag control unit with part number 95910-3F300 is the central control unit for the occupant restraint system. Its primary task is to process sensor data in order to deploy the airbags and seatbelt pretensioners precisely and at the right moment in the event of a crash.

As the primary OEM control unit for the Kia Opirus GH, it continuously monitors the vehicle’s acceleration and yaw rate sensors. If the system detects a collision exceeding predefined thresholds, it sends ignition signals to the corresponding pyrotechnic components of the safety system.

In addition, the control unit performs a self-test every time the vehicle is started and continuously monitors all connected components—such as sensors, airbags, and seatbelt pretensioners—for proper functionality. Any detected fault is indicated by the airbag warning light in the cockpit.

What types of defects occur in the control unit 95910-3F300?

The most common causes of failure for the control unit 95910-3F300 are stored crash data following an accident or internal defects in electronic components. These faults prevent the safety system from functioning properly and require professional repair.

After a collision, the control unit permanently stores so‑called crash data. This data storage is a safety feature that locks the device, preventing further use without professional reset. In such cases, the airbag warning light remains constantly illuminated.

Another frequent source of failure is damage to internal electronic components on the circuit board. Aging processes or voltage spikes can harm parts like processors, memory chips, or capacitors, leading to total failure or communication errors. For the Kia Opirus GH, in addition to part number 95910-3F300, the alternative OEM number 56910-3E050CQ is also known to be susceptible to similar defects.

Repairing these defects offers a cost‑effective alternative to replacing the entire unit. The cost of repairing comparable airbag control units in the German market ranges from €90 to €300, depending on the nature of the fault and the effort required.

How do you recognize a defect in the airbag control unit?

A defect in the control unit 95910-3F300 primarily manifests as a permanently illuminated airbag warning light in the instrument cluster. Additionally, specific error codes may be stored in the vehicle’s diagnostic memory, indicating an internal control unit malfunction.

The most obvious symptom is the airbag warning light that does not turn off after the engine starts. This alerts the driver that the passive safety system is either non‑functional or only partially operational and would fail to deploy correctly in the event of a crash.

When diagnosed with a workshop scanner, error codes directly related to the control unit—such as “Internal Error” or “Crash Data Stored”—can often be retrieved. Such errors cannot be cleared using standard diagnostic tools.

In which vehicles is part number 95910-3F300 installed?

Part number 95910-3F300 is the original airbag control unit specifically designed for the Kia Opirus GH vehicle series. The alternative OEM part number 56910-3E050CQ is also used in this model and may exhibit the same defects.

At Airbag24, the control unit with part number 95910-3F300 is repaired for the following specific model:

Kia Opirus GH (model years 2003–2010)

How does the repair of the control unit 95910-3F300 proceed?

At Airbag24, each control unit undergoes a professional repair process. This includes an initial analysis, actual restoration through clearing crash data or replacing faulty components, and a final functional test. All repairs come with 2 years' statutory liability for defects.

Upon receipt of the removed control unit, a comprehensive fault diagnosis is performed to determine the exact cause of the defect. Drawing on over 20 years of experience and more than 20,000 repairs, the fault is precisely localized.

The subsequent repair involves, depending on the nature of the fault, either professionally erasing the stored crash data or replacing defective electronic components on the circuit board. After successful restoration, the control unit is reset so that the airbag warning light functions correctly again once reinstalled.
