Airbag control unit with part number 95910-K4000

What does the airbag control unit 95910-K4000 do?

The airbag control unit 95910-K4000 is responsible for the SRS restraint system in the Hyundai. It checks the crash sensors, decides in an accident within milliseconds whether airbags and seatbelt pretensioners deploy, and monitors the system permanently. After an accident it stores crash data and locks itself.

With every fault, the unit creates an entry in the fault memory. The airbag warning light in the instrument cluster shows you that something is wrong.

Why does the control unit 95910-K4000 fail?

The most common cause is crash data that remains in the unit after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Reading out with a diagnostic tool changes nothing in the crash data, since the tool cannot remove it.

The other causes concern the hardware. Aged electronics and cold solder joints can trigger faults.

Moisture and corrosion at plug connections impair the contact, and voltage spikes from the vehicle electrical system, for example with a weak battery or a jump start, strain the electronics. Airbag24 erases crash data during the repair.

How can you tell that the 95910-K4000 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and an error message appears in the instrument cluster. In addition, the diagnostic tool makes no connection, or the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The warning light can be trusted: it shows a fault even when the vehicle reacts completely normally in daily use. That a car drives therefore does not mean the restraint system works without faults.

Have the display checked promptly.

For the same vehicles, we also repair control units with the part numbers 95910-CM200, 95910-DF100, 95910-J9100, 95910-J9200, 95910-K4100.

How does the repair of the 95910-K4000 work?

First have the fault memory read out and attach the log. Then disconnect the battery and only afterwards remove the control unit. Create the repair order online, then send the well-packed unit.

The fixed order of these steps serves safety on the airbag system.

Airbag24 checks the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test. Processing at Airbag24 usually takes 3–4 working days. Afterwards the 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-K4000 get to Airbag24?

You send the unit yourself as a parcel to Airbag24, or you book a UPS collection for an extra charge. Airbag24 handles the return by UPS.

The printed repair order comes into the parcel, and the unit needs a shockproof casing.
