Airbag control unit with part number 95910-P4400

What does the airbag control unit 95910-P4400 do?

The airbag control unit 95910-P4400 is the central control unit of the SRS restraint system in Kia. It captures the signals of the crash sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners are activated, and checks the system continuously. It indicates detected faults via the airbag warning light.

If an accident occurs, the unit stores crash data and then locks itself. This storage happens regardless of whether an airbag was triggered.

In workshop operations the control unit is therefore the first point of contact: this is where the messages of the restraint system come together, and the diagnostic tool reads them from there.

Why does the control unit 95910-P4400 fail?

The most common cause is stored crash data after an accident, even without an airbag being triggered; a normal diagnostic tool cannot erase it. Further causes are aged components, cold solder joints, moisture and corrosion on connectors, and voltage spikes.

The other causes at a glance:

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

Which cause applies in an individual case is clarified by reading out the fault memory together with an examination of the unit.

How can you tell that the 95910-P4400 is defective?

A defect shows up first in the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Fault messages, a missing connection between the diagnostic tool and the control unit and a fault memory that cannot be cleared are added. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The warning light is the sign you notice first in daily use. A fault message in the instrument cluster follows as soon as the system has registered a fault. With these signs a prompt check is advisable.

A fault memory that cannot be cleared does not automatically mean that the unit is defective. Only the readout shows the cause in more detail.

Which vehicles is the 95910-P4400 fitted in?

Before sending in, two steps are recommended. Compare the part number on the label with this page so that you have the right unit. Have the fault memory read out, because only the result shows whether the control unit is defective or a connector or 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-P4400 work?

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

At Airbag24 the unit is checked on the test bench, defective components are replaced, stored crash data is deleted and a function test is run. Afterwards your own unit is returned to you.

The sequence serves safety, so the control unit may only be removed after the battery has been disconnected.

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-P4400 get to Airbag24?

Either you pack the control unit as a parcel yourself, or you book a UPS collection for an extra charge. After the repair Airbag24 sends the unit back by UPS.

The printed repair order goes into the parcel. Pack the unit shockproof so it survives transport undamaged.
