Airbag control unit with part number 95910-3V300

What does the airbag control unit 95910-3V300 do?

In the SRS restraint system of Hyundai, the airbag control unit 95910-3V300 controls all triggering processes. It evaluates the crash sensors, determines in an accident which airbags and seatbelt pretensioners fire, and makes faults visible via the airbag warning light.

It checks the signals from the crash sensors continuously. If an accident occurs, the unit secures the crash data and remains locked afterwards.

Why does the control unit 95910-3V300 fail?

The most common cause with the 95910-3V300 is crash data stored even without a triggered airbag. They cannot be reset with a normal diagnostic tool. Aged components, moisture and voltage spikes are additional possibilities.

These further possibilities come into question:

• aging electronic components
• cold solder joints on the circuit board
• moisture and corrosion at plug connections
• voltage spikes from a weak battery or a jump-start

How can you tell that the 95910-3V300 is defective?

A defect in the 95910-3V300 can be recognised by the airbag warning light in the instrument cluster, if it is on constantly or in between times. Error messages in the instrument cluster, a missing contact to the diagnostic tool and a fault memory that cannot be emptied also point to it.

Prompt clarification is therefore advisable. As long as the control unit is faulty, the airbags and seatbelt pretensioners may not trigger in an emergency.
