Airbag control unit with part number 95910-B8780

What does the airbag control unit 95910-B8780 do?

The airbag control unit 95910-B8780 coordinates the SRS restraint system of Hyundai. It processes the measurement data of the crash sensors, determines in an impact which airbags and seatbelt pretensioners are triggered, and monitors the system on an ongoing basis. Detected faults appear on the airbag warning light.

After an accident the unit creates crash data and locks itself. It has no display of its own.

The monitoring takes place without any action on your part and covers all important components of the system.

Why does the control unit 95910-B8780 fail?

Stored crash data is the most common cause, even if no airbag has fired; an ordinary diagnostic tool cannot delete it. Besides this, aged components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes, come into consideration.

For the diagnosis it is decisive that the memory keeps entries even after an incident without consequences.

The other causes act quietly in everyday use: components age, solder joints can break, and moisture promotes corrosion at plugs. Voltage spikes arise, for example, from a weak battery or when a jump start is connected.

How can you tell that the 95910-B8780 is defective?

The airbag warning light in the instrument cluster comes on permanently or intermittently. In addition, the instrument cluster shows a message, the diagnostic tool cannot reach the control unit, and the fault memory cannot be emptied. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The light and the message are your reason to arrange a check promptly.
