Airbag control unit with part number 95910-2W880

What does the airbag control unit 95910-2W880 do?

The airbag control unit 95910-2W880 coordinates the restraint system (SRS) of Hyundai. It evaluates the crash sensors, determines in a crash which airbags and seatbelt pretensioners trigger, and monitors the system continuously. It shows faults via the airbag warning light.

The sensor readings converge in the control unit. There it is checked whether an impact requires a trigger, and this happens within a very short time.

After an accident, the unit stores crash data and locks itself. The lock affects the unit itself.

As long as everything is in order, you will notice nothing from the control unit while driving.

Why does the control unit 95910-2W880 fail?

The most common cause is crash data that remains in memory after an accident, even if no airbag has triggered; a standard diagnostic tool cannot erase it. Also possible are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery or a jump start.

Stored crash data can trigger an error message even though the electronics need not be damaged. Airbag24 clarifies this case directly by erasing the data.

The other causes concern components and connections. Electronic components lose reliability with age, solder joints can be cold, and moisture attacks the contacts. Voltage spikes act on the circuit when the power supply fluctuates.

Which cause applies can only be determined by the test on the test bench.

How can you tell that the 95910-2W880 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared. With a defect, airbags and seatbelt pretensioners may not trigger in a crash.

The airbag warning light in the instrument cluster indicates a defect when it lights up permanently or intermittently. Note when this happens, as that helps with diagnosis.

An error message may also appear in the instrument cluster. If the diagnostic tool cannot connect to the control unit, or the fault memory remains, this is likewise a sign of a fault.

A comparison of the part number on the label of the removed unit with this page confirms that it is the right unit. Please have the fault memory read out beforehand, because only this result shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 95700-2B110, 95910-0W100, 95910-26100, 95910-2B028, 95910-2B900, 95910-2B970.

How does the repair of the 95910-2W880 work?

First have the fault memory read out and enclose the log. Then disconnect the battery and only then remove the control unit. Finally create a repair order online and send in the well-packed unit.

The order is fixed for safety reasons. All work on the airbag system is carried out in this sequence only.

Airbag24 examines the unit on the test bench, replaces defective components, erases the crash data and carries out a function test. Processing at Airbag24 usually takes 3–4 working days. Afterwards your own unit comes 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 95910-2W880 get to Airbag24?

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

Put the printed repair order into the parcel and pack the control unit shockproof.
