Airbag control unit with part number 95910-CH620

What does the airbag control unit 95910-CH620 do?

The airbag control unit 95910-CH620 controls the restraint system (SRS) for Hyundai. It processes the measured values of the crash sensors, decides in a crash within milliseconds on the deployment of airbags and seatbelt pretensioners, and monitors the entire system continuously.

The control unit reports faults via the airbag warning light in the instrument cluster. This is how you notice a malfunction before it becomes a problem in an emergency.

After an accident, it stores crash data and locks itself. This lock ends only with a repair.

Why does the control unit 95910-CH620 fail?

Stored crash data after an accident is the most common cause, even if no airbag has deployed. Other possible causes are ageing electronics, cold solder joints, moisture at plug connections and voltage spikes, for example from a weak battery or a jump start.

Crash data arises even in accidents where no airbag deploys. An ordinary diagnostic tool cannot erase it; Airbag24 removes it during the repair.

The other causes lie in the electronics themselves. Components age, solder joints on the circuit board can turn cold, and moisture or corrosion at plug connections disrupt the signal transmission. Voltage spikes additionally stress the electronics.

How can you tell that the 95910-CH620 is defective?

The airbag warning light in the instrument cluster lights up constantly or only intermittently, an error message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, or the fault memory cannot be cleared. In such cases, airbags and seatbelt pretensioners may not trigger in an emergency.

A fault shows up in the vehicle via the warning light. A light that comes on and goes out again is also a sign that you should have checked.

Have such signs examined promptly. Only a diagnosis shows how the control unit is doing.

Which vehicles is the 95910-CH620 fitted in?

• Hyundai Tucson NX4 (2020-2023)
• Hyundai Tucson NX4 Facelift (from 2023)

Comparing the part number on the label of the removed unit with this page only confirms that it is the right unit. Have the fault memory read out in addition, 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 28394001, 95910-2S750, 95910-CZ000, 95910-D7130, 959102S850, A3C03656003.

How does the repair of the 95910-CH620 work?

You first have the fault memory read out and attach the log. Then you disconnect the battery, remove the control unit and create a repair order online before sending in the well-packed unit.

This order protects you when working on the airbag system. The battery is disconnected before removal, not after.

Airbag24 tests the submitted unit on the test bench, replaces defective components, erases stored crash data and tests the function. Afterwards your own unit goes back to you. Processing at Airbag24 usually takes 3–4 working days.

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-CH620 get to Airbag24?

You send the unit as a parcel yourself, or you book a UPS collection for an extra charge. Airbag24 sends the repaired unit of your own back by UPS.

The printed repair order goes into the parcel. Pack the control unit shock-proof before you hand it over.
