Airbag control unit with part number 95910-P4500

What does the airbag control unit 95910-P4500 do?

The control unit 95910-P4500 is the central control unit of the restraint system (SRS) of Kia. It evaluates the signals from the crash sensors, decides within a few milliseconds in the event of an accident which airbags and seatbelt pretensioners to trigger, and monitors the system continuously. After an accident, it stores crash data and locks itself.

In the background, the control unit constantly checks whether the sensors, wiring and firing units are in order. If it detects a deviation, it reports it via the airbag warning light in the instrument cluster.

Stored crash data remain in the unit even if no airbag has deployed in the accident. That is why it is worth having the system checked after every accident.

Why does the control unit 95910-P4500 fail?

The most common cause: crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it; Airbag24 erases it during the repair. Other causes include aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

The crash data are held in the unit's memory. In everyday use you notice nothing of it as long as no fault message appears.

The other causes develop over time. Electronics age, solder joints on the circuit board can go cold, and moisture combined with corrosion attacks plug connectors.

Voltage spikes, for example from a weak battery or a jump start, put additional strain on the electronics. Which cause is actually present only becomes clear when the unit is tested on the test bench.

How can you tell that the 95910-P4500 is defective?

A defect shows up as an airbag warning light in the instrument cluster that lights up permanently or intermittently, as a fault message in the instrument cluster, as a lack of connection to the diagnostic tool, or as a fault memory that cannot be cleared. In that case, the airbags and seatbelt pretensioners may not be able to deploy in an emergency.

The airbag warning light in the instrument cluster is the clearest sign that the restraint system has detected a deviation. It should therefore not be ignored.

A diagnostic tool that cannot establish a connection to the control unit, or a fault memory that cannot be reset, points to a fault. An inspection will establish where it comes from.

First, compare the part number on the label of the removed unit with this page. This only ensures that it is the right unit. Second, have the fault memory read out before removal. Only this result shows whether the control unit is defective or whether a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 95910-P2100, 95910-P4250.

How does the repair of the 95910-P4500 work?

First, have the fault memory read out and enclose the log. Then disconnect the battery, only then remove the control unit, and create a repair order online. Finally, send in the well-packed unit.

Airbag24 checks the unit you send in on the test bench, repairs defective components, erases stored crash data and carries out a function test.

Processing at Airbag24 usually takes 3–4 working days. After that, your own unit is returned 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-P4500 get to Airbag24?

You send in the control unit 95910-P4500 as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 sends it back to you by UPS.

Put the printed repair order into the parcel and pack the unit shock-proof.
