Airbag control unit with part number 95910-K3900

What does the airbag control unit 95910-K3900 do?

The airbag control unit 95910-K3900 forms the switching point of the restraint system (SRS) in Kia. It processes the messages from the crash sensors and, in an accident, decides within milliseconds whether airbags and seatbelt pretensioners are triggered. It checks the system continuously and shows faults via the airbag warning light.

The sensors and wiring supply the measured values, while the control unit makes the decision.

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

Why does the control unit 95910-K3900 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Other causes lie in the electronics themselves or in the connection technology.

• aged electronics
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery

A standard diagnostic tool does not erase crash data. It therefore stays in memory until a repair removes it.

Which cause applies in an individual case can only be shown by examining the unit.

How can you tell that the 95910-K3900 is defective?

A defect shows up as the airbag warning light, as messages in the instrument cluster and as a diagnostic tool that cannot establish a connection. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

• airbag warning light stays on permanently or intermittently
• error message in the instrument cluster
• no connection to the diagnostic tool
• fault memory cannot be cleared

The light reports the fault itself. Pay attention to when it comes on and whether it goes out again.

If any of these signs appear, have a specialist workshop check the vehicle before you remove the control unit.

• Kia Soul SK3 (from 2019)

Comparing the part number on the label of the removed unit with this page only confirms that you have the right unit. Also have the fault memory read out, because only that log shows whether the control unit itself is defective or whether a plug or cable is the cause.

How does the repair of the 95910-K3900 work?

First have the fault memory read out, then disconnect the battery and remove the control unit. Afterwards you create a repair order online and send the unit in. Processing at Airbag24 usually takes 3–4 working days.

Airbag24 checks the unit on the test bench, replaces defective components, deletes stored crash data and carries out a function test. The unit then comes back to you.

The 3–4 working days relate solely to this work at Airbag24.

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-K3900 get to Airbag24?

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

Place the printed repair order in the parcel and pack the unit so it is shock-resistant.
