Airbag control unit with part number 95910-G7400

What is the function of the airbag control unit 95910-G7400?

The airbag control unit with part number 95910-G7400 is the central control module for the passive safety system (SRS) in the Hyundai Ioniq AE. It processes data from acceleration and crash sensors to precisely deploy the airbags and seatbelt pretensioners at the right moment in the event of a collision, thereby protecting the occupants.

As the “brain” of the restraint system, this module continuously monitors all connected components—from front and side airbags to seatbelt pretensioners and sensors. In case of a malfunction or detected fault, it illuminates the airbag warning light on the instrument panel to alert the driver.

Why does the control unit 95910-G7400 fail?

The most common cause of failure for the 95910-G7400 is the storage of crash data after an airbag deployment. Other defects arise from internal electronic faults on the circuit board, moisture damage, or issues with external wiring and connectors. Replacement is not always mandatory.

After a crash in which the airbags have deployed, the control unit locks itself internally. This lock—manifested as “crash data”—cannot be cleared using standard diagnostic tools, making the component appear unusable. This is a manufacturer‑specified safety feature.

Moreover, malfunctions can occur even without a crash. Defective electronic components on the circuit board, cold solder joints, or corrosion caused by ingress of moisture can also lead to malfunctions or complete failure of the control unit.

How do you recognize a defect in the 95910-G7400?

A defective airbag control unit 95910-G7400 primarily manifests as a permanently illuminated or flickering airbag warning light (SRS light) on the dashboard. Often, communication with the control unit via a diagnostic tool is no longer possible, or non‑erasable fault codes are displayed.

The most obvious symptom is the persistently lit SRS warning light. It does not turn off after starting the engine, indicating a serious, stored error within the system.

Another clear sign is when a workshop’s diagnostic equipment can no longer access the airbag control unit. It fails to respond to queries, rendering fault diagnosis impossible.

Sometimes specific fault codes such as “side sensor error” or “internal component defect” are reported and cannot be cleared. The presence of crash data—even if no accident has occurred—also points to an internal fault.

Atypical electrical phenomena, such as a delayed illumination of the warning light after starting or residual glow from the dashboard lights after turning off the vehicle, may likewise indicate a defect in this control unit.

In which vehicles is the 95910-G7400 installed?

The airbag control unit with part number 95910-G7400 was specifically developed for the Hyundai Ioniq AE vehicle platform. At Airbag24, we repair this control unit for the entire model range, including the facelift version. Repairs are available for all engine types and trim levels of these models.

At Airbag24, repairs for the 95910-G7400 control unit are offered for the following Hyundai models:

Hyundai Ioniq AE (model years 2016–2019)

Hyundai Ioniq AE Facelift (model years 2019–2022)

It is important to verify the part number before removal. Similar numbers like 95910-M7400 may be used in other models but are not necessarily compatible.

How is the 95910-G7400 professionally repaired?

Professional repair at Airbag24 begins with a detailed diagnosis of the fault memory. Depending on the nature of the defect, stored crash data is reset using specialized software, or faulty electronic components on the circuit board are replaced. A final test ensures full functionality.

Upon submission to Airbag24, the repair follows a proven procedure. First, the internal fault memory is read to pinpoint the exact cause—whether it’s a hardware issue or a software lock due to crash data.

If stored accident data is present, a so‑called “crash reset” is performed, electronically restoring the control unit to its pre‑accident state. If a component defect is identified, the faulty parts on the circuit board are located and replaced with new, high‑quality components.

Following restoration, a comprehensive functional test and calibration are carried out to ensure the control unit communicates flawlessly with the vehicle again and correctly manages all safety functions. We provide 2 years' statutory liability for defects on every repair.
