Airbag control unit with part number 95910-P2120

What does the airbag control unit 95910-P2120 do?

The airbag control unit 95910-P2120 controls the restraint system (SRS) of Kia and is therefore responsible for triggering the airbags and seatbelt pretensioners. It reads the signals from the crash sensors, evaluates them and makes the decision in the event of an accident within milliseconds. After an accident it stores crash data and locks itself.

Monitoring runs in the background throughout every journey. The unit continuously checks the wiring and sensors, and every fault it detects appears as a message on the airbag warning light in the instrument cluster. This way the driver learns that something is wrong with the restraint system.

Triggering follows fixed criteria. Which airbag or which seatbelt pretensioner responds depends on the direction and type of impact. The control unit takes into account exclusively the measured values that its sensors supply.

Why does the control unit 95910-P2120 fail?

The most common cause is crash data from an accident, even if no airbag has deployed; a normal diagnostic tool cannot remove it. Other causes are aged components, moisture, corrosion and voltage spikes.

Crash data is created in the control unit during the impact and remains stored there. A standard diagnostic scan does not remove it, so the entry stays in memory.

Which of the other causes applies can only be determined on the unit itself. Typical points are:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 95910-P2120 is defective?

A defect becomes visible through an airbag warning light in the instrument cluster that stays lit permanently or intermittently. Other signs include a fault message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

The warning light is the clearest sign of a fault in the restraint system. It comes on because the control unit has detected a fault, not by chance.

A missing connection to the diagnostic tool also prevents the fault memory from being read. In the meantime, airbags and seatbelt pretensioners may not trigger in an emergency, which is why it is important to clarify the cause promptly.

Two checks are worthwhile before removal. Comparing the part number on the unit's label with this page only confirms that it is the right unit. Have the fault memory read as well, because only this log shows whether the control unit itself 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-P2120 work?

First have the fault memory read and attach the log. Then disconnect the battery, and only then remove the control unit. After that, create a repair order online and send in the unit.

At Airbag24 the unit is examined on the test bench. Defective components are repaired, stored crash data is deleted, and a function test completes the work. The unit then returns to you. Processing 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-P2120 get to Airbag24?

You either send the unit yourself as a parcel, or you book a UPS pickup for an extra charge. The return after repair is likewise made by UPS.

Enclose the printed repair order with the parcel. Pack the unit so that it is shock-resistant.
