Airbag control unit with part number 95910-K4300

What does the airbag control unit 95910-K4300 do?

The airbag control unit 95910-K4300 coordinates the SRS restraint system in the Hyundai vehicle. It checks the crash sensors and, in the event of an impact, decides within milliseconds which airbags and seatbelt pretensioners are triggered. It also monitors the entire system without interruption and reports faults via the airbag warning light.

The monitoring covers sensors, seatbelt pretensioners and airbag modules alike.

After an accident, the unit writes crash data to its memory and locks itself.

Why does the control unit 95910-K4300 fail?

The most common cause is an entry in the memory left behind by an earlier accident, even if no airbag fired. These crash data cannot be removed with common reading devices. Added to this are ageing components, dry solder joints, moisture or corrosion in plug connections, and voltage spikes such as those from a weak battery.

Ageing electronic components lose reliability over time. A dry solder joint creates a wobbly contact that can come loose under load.

Moisture gets into plug connections and promotes corrosion, while voltage spikes from a weak battery or a jump start put strain on the electronics.

How can you tell that the 95910-K4300 is defective?

A defect shows itself through the airbag warning light, which lights up permanently or only intermittently. A message also appears in the instrument cluster, and a diagnostic tool finds no access to the control unit. In addition, the fault memory remains and cannot be reset. With these signs, airbags and seatbelt pretensioners may fail to deploy in an emergency.

The light is the warning signal with which the system indicates faults. If it stays on, a check without delay is the right course.

A diagnostic tool does not get a stable connection to a faulty control unit. The cause is then not apparent at first glance, which is why an orderly check is needed.

Which vehicles is the 95910-K4300 fitted in?

Check first whether the part number on the label of the removed unit matches this page, so that you have the correct unit. Also have the fault memory read out before removal. Only the log shows whether the control unit itself is defective or whether a connector or cable is the cause.

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-K4300 work?

First have the fault memory read out and enclose the log; then disconnect the battery and only after that remove the control unit. Then create the repair order online and send the well-packed unit in. Airbag24 tests it, repairs defective components, clears crash data and carries out a function test; this takes 3–4 working days as a rule.

Keep to the sequence, as it protects you when working on the airbag system.

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-K4300 get to Airbag24?

The unit reaches Airbag24 either as a parcel or with a UPS collection booked for an extra charge. UPS then brings it back to you.

Include the printed repair order and pack the unit shock-proof.
