Airbag control unit with part number 95910-2B270

What does the airbag control unit 95910-2B270 do?

The airbag control unit 95910-2B270 controls the SRS restraint system at Hyundai. It processes the signals from the crash sensors, determines the appropriate airbags and seatbelt pretensioners within milliseconds in an emergency, and monitors the system permanently. Faults appear via the airbag warning light.

The electronics keep an eye on every connected sensor and every triggering device. After an accident, they store crash data and then lock.

Why does the control unit 95910-2B270 fail?

Most often the cause is crash data from an earlier accident, even if no airbag was triggered in it. An ordinary diagnostic tool cannot reach this data to erase it. Aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes also play a part.

Aged components lose reliability over time without this initially being noticeable.

Cold solder joints can interrupt a connection only intermittently, which makes fault-finding harder.

Moisture and corrosion slowly attack plug connectors, while voltage spikes, for example from a weak battery, strain the electronics suddenly.

How can you tell that the 95910-2B270 is defective?

The airbag warning light in the instrument cluster indicates the fault by lighting up permanently or intermittently. In addition, an error message appears, the diagnostic tool finds no connection, and the fault memory cannot be cleared.

It is precisely this warning light that means the system is not working properly. In an emergency, airbags and seatbelt pretensioners may therefore fail to deploy.

If the part number on the label of your removed unit matches this page, it is the correct unit. However, have the fault memory read out beforehand, so that it becomes clear whether the control unit itself is faulty or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 95700-2B110, 95910-2B900, 95910-2B970.

How does the repair of the 95910-2B270 work?

First have the fault memory read out and enclose the log; then disconnect the battery and only then remove the unit. Next, create a repair order online and send the unit in well packed. At Airbag24, processing usually takes 3–4 working days.

Airbag24 checks the unit on the test bench and repairs defective components. The crash data is then removed by the team, a function test completes the work, and your own unit goes back to you.

Our repairs come with 2 years' statutory liability for defects.

The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 95910-2B270 get to Airbag24?

You hand over the unit as a parcel to a carrier, or book UPS collection for an extra charge. The return after repair is handled by Airbag24 via UPS.

A printed repair order belongs in the shipment, and the unit should be packed shockproof.
