Airbag control unit with part number 95910-3V450

What does the airbag control unit 95910-3V450 do?

For Hyundai, the airbag control unit 95910-3V450 is the central control of the SRS restraint system. It continuously evaluates the crash sensors, decides within milliseconds in the event of an impact which airbags and seatbelt pretensioners are activated, and reports faults via the airbag warning light.

The unit checks the signals continuously for plausibility and for the connections to the components.

After an accident, it stores crash data and locks itself.

Why does the control unit 95910-3V450 fail?

The most common causes are crash data stored in the unit after an accident, even if no airbag was triggered; a normal diagnostic tool cannot remove it. Further causes are aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes that occur, for example, with a weak battery or jump-starting.

The crash data remains in the memory after the accident, without anything being visible from the outside.

Electronics age, solder joints can go cold, and moisture causes corrosion on the plugs. If the battery is weakening or a jump-start feeds voltage into the vehicle electrics, voltage spikes arise that stress the circuits.

How can you tell that the 95910-3V450 is defective?

A defect shows first on the airbag warning light in the instrument cluster, which stays on permanently or only intermittently. Error messages, a missing contact with the diagnostic tool or a fault memory that cannot be cleared are further indications. Airbags and seatbelt pretensioners may then possibly fail to trigger in an emergency.

When the ignition is switched on, the light runs a self-test; if it does not go out afterwards, have the finding checked.

Even if the display disappears at times, the fault is not thereby resolved.

The fault memory must be read out above all else. The result shows whether the control unit itself is defective or whether a plug or a cable is the cause. You can also make the label comparison; it establishes the identity of the unit, not the cause.

For the same vehicles, we also repair control units with the part numbers 95910-3V000, 95910-3V250, 95910-E7000.

How does the repair of the 95910-3V450 work?

You read out the fault memory first, and the log goes with the unit. Then you disconnect the battery, remove the control unit, create a repair order online and send the unit off well packed.

Airbag24 then checks the unit on the test bench, repairs defective components, deletes the stored crash data and tests the function. Processing at Airbag24 usually takes 3–4 working days.

Your own unit is then returned to you. The sequence in the vehicle is binding for your safety. 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 95910-3V450 get to Airbag24?

One parcel is enough to send the control unit to Airbag24. Alternatively, you book a UPS collection for an extra charge, and the return shipment is again made by UPS.

Place the printed repair order in the parcel and pack the control unit so that it withstands knocks.
