Airbag control unit with part number 95910-2S350

What does the airbag control unit 95910-2S350 do?

The airbag control unit 95910-2S350 is the central control unit of the SRS for Hyundai. It continuously checks the signals of the crash sensors and decides in an accident which airbags and seatbelt pretensioners fire. Faults are shown via the airbag warning light.

The evaluation takes place within fractions of a second. Where sensors and actuators work together, the control unit takes over the coordination.

After an accident it stores crash data, and afterwards it locks itself. The lock is a fixed part of the unit's logic.

Why does the control unit 95910-2S350 fail?

The most common cause of a defective 95910-2S350 is stored crash data, even if no airbag has fired. A normal diagnostic tool cannot erase it. Aged components, cold solder joints, moisture and voltage spikes are also possible causes.

That the data can be erased means for you: Airbag24 removes it in the course of the repair.

The other causes are ageing of the electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

How can you tell that the 95910-2S350 is defective?

A defect on the 95910-2S350 can be recognised by the airbag warning light in the instrument cluster, which lights permanently or intermittently. Further signs point to the control unit as well.

• airbag warning light lights permanently or intermittently
• fault message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory cannot be erased

In such a case, airbags and seatbelt pretensioners may possibly not deploy in an emergency. A prompt check is therefore advisable.
