Airbag control unit with part number 95910-1R300

What does the airbag control unit 95910-1R300 do?

The airbag control unit 95910-1R300 is the central control unit of the restraint system (SRS) of Hyundai. It evaluates the signals from the crash sensors, decides in an accident within milliseconds whether to trigger the airbags and seatbelt pretensioners, and monitors the system continuously.

The unit reports faults via the airbag warning light in the instrument cluster. Anyone who pays attention to this light recognises disturbances in the restraint system early.

After an accident, the unit stores crash data and locks itself. This is part of its function.

Why does the control unit 95910-1R300 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot delete this data.

Beyond that, ageing electronic components can cause the failure. Cold solder joints, as well as moisture and corrosion at plug connections, also come into consideration.

Voltage spikes, for example from a weak battery or jump-starting, are likewise possible triggers. Airbag24 deletes the stored crash data during the repair.

How can you tell that the 95910-1R300 is defective?

A defect shows itself through an airbag warning light that stays on permanently or intermittently, through a fault message in the instrument cluster, through a diagnostic tool without a connection to the control unit, or through a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. You should therefore not ignore such signs.

Processing at Airbag24 usually takes 3–4 working days. It covers checking, repairing and testing the unit.

Before removal, have the fault memory log ready. Then disconnect the battery, remove the control unit, create the repair order online and pack the unit well for dispatch.

At Airbag24, the unit first goes onto the test bench. The workshop replaces defective components, deletes crash data and completes the work with a function test. The unit then 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 95910-1R300 get to Airbag24?

You send the unit as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 sends the control unit back by UPS.

The printed repair order belongs in the parcel, and the unit should be packed shock-resistant.
