Airbag control unit with part number 95910-4D720

What does the airbag control unit 95910-4D720 do?

The airbag control unit 95910-4D720 forms the central control unit of the restraint system (SRS) for Kia. It evaluates the signals from the crash sensors and decides in a crash, within milliseconds, which airbags and seatbelt pretensioners are triggered.

The system continuously monitors the control unit and reports faults via the airbag warning light. After an accident the unit stores crash data and locks itself.

It is thus the junction between sensors, wiring and triggering elements, and faults can arise at any of these points.

Why does the control unit 95910-4D720 fail?

The most common cause for 95910-4D720 is crash data stored after an accident, even if no airbag has triggered. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data remains stored in the control unit after an accident, even if no airbag was triggered. It cannot be deleted with a normal diagnostic tool. Airbag24 deletes it during the repair.

The other causes mainly concern the electronics themselves and their connections. Components age, solder joints can be cold, and moisture or corrosion at plugs impairs signal transmission. Voltage spikes, for example from a weak battery or a jump start, additionally stress the components.

How can you tell that the 95910-4D720 is defective?

A defect in 95910-4D720 shows up as the airbag warning light in the instrument cluster, a fault message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

The airbag warning light in the instrument cluster is the signal you will notice first. It lights up constantly or only intermittently, accompanied by a fault message in the instrument cluster.

If no connection to the control unit is established or the fault memory cannot be emptied, the system is faulty. In an emergency, airbags and seatbelt pretensioners may then not trigger.
