Airbag control unit with part number 95910-B8180

What does the airbag control unit 95910-B8180 do?

The airbag control unit 95910-B8180 controls the restraint system (SRS) in Hyundai. It evaluates the crash sensors, decides within milliseconds in an accident on the triggering of airbags and seatbelt pretensioners, and reports faults via the airbag warning light.

During operation the unit continuously monitors sensors, power supply and connections. Detected deviations are stored in the fault memory so that they become visible when read out.

After an accident it records crash data and then locks itself. Only the repair lifts this lock again.

Why does the control unit 95910-B8180 fail?

The most common cause is crash data stored after an accident, even if no airbag has triggered. Also involved are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A normal diagnostic tool cannot erase this crash data, so the fault persists. This also applies when nothing conspicuous can be seen on the vehicle itself.

The other causes relate to ageing, contacts and the power supply. Moisture and corrosion attack plug connections, cold solder joints can cause contact problems, and voltage spikes occur, for example, with a weak battery or when a jump start is given.

How can you tell that the 95910-B8180 is defective?

The airbag warning light lights up continuously or intermittently. In addition the instrument cluster shows an error message, the diagnostic tool cannot reach the control unit, and the fault memory remains.

• airbag warning light that lights up continuously or only intermittently
• error message in the instrument cluster
• diagnostic tool without connection to the control unit
• fault memory that cannot be cleared

If such signs appear, airbags and seatbelt pretensioners may in an emergency not trigger. The warning light is therefore a sign that you should take seriously.

On the one hand, comparing the part number on the label of the removed unit with this page confirms that it is the right unit. On the other hand, have the fault memory read before the control unit is removed, 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-B8180 work?

Airbag24 checks the unit on the test bench, replaces defective components, erases the crash data and carries out a function test. Afterwards the unit goes back to the sender.

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-B8180 get to Airbag24?

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

Enclose the printed repair order in the parcel, and pack the unit shock-resistant.
