Airbag control unit with part number 95910-4M450

What does the airbag control unit 95910-4M450 do?

The airbag control unit 95910-4M450 forms the central unit of the restraint system (SRS) at Kia. It processes the measured values of the crash sensors and decides within milliseconds in an accident which airbags and seatbelt pretensioners fire.

The unit monitors the system continuously. If it detects a fault, it switches on the airbag warning light so that the finding becomes visible in the instrument cluster.

After an accident it stores crash data and locks itself.

Why does the control unit 95910-4M450 fail?

The most common cause is crash data from an accident that remains in the unit even if no airbag has fired. Also possible are aged components in the electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump-start.

A normal diagnostic tool cannot remove this crash data. The removal takes place at Airbag24 as part of the repair.

Further weak points lie in connections that age over the years. A look at the plug connections already shows whether corrosion or moisture is involved.

How can you tell that the 95910-4M450 is defective?

A defective control unit announces itself through the airbag warning light in the instrument cluster, which lights constantly or intermittently. In addition an error message appears in the instrument cluster, and the fault memory remains.

• The airbag warning light is constantly on or keeps coming on.
• An error message regarding the airbag system is shown in the instrument cluster.
• The diagnostic tool finds no connection to the control unit.
• The fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then possibly not deploy. The light indicates the finding, and that calls for a prompt check.
