Airbag control unit with part number 95910-2B400

What does the airbag control unit 95910-2B400 do?

The airbag control unit 95910-2B400 is the central control unit of the SRS for vehicles of the Hyundai brand. It evaluates the crash sensors, determines in an accident within fractions of a second which airbags and seatbelt pretensioners are triggered, and checks the system continuously.

If it detects a fault, it stores it in the fault memory and shows it via the airbag warning light in the instrument cluster. After an accident the unit stores crash data and locks itself. This lock is lifted only by the repair.

Why does the control unit 95910-2B400 fail?

The cause is most often crash data stored after an accident, even if no airbag has deployed. Aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes are also possible.

A normal diagnostic tool cannot erase crash data. They therefore stay in the memory until Airbag24 removes them during the repair.

Electronic components age over time. Solder joints can go cold, and moisture attacks plug connections. Voltage spikes arise, for example, with a weak battery or a jump start.

How can you tell that the 95910-2B400 is defective?

You recognise a defect in the 95910-2B400 by the airbag warning light, fault messages in the instrument cluster, a diagnostic tool that cannot establish a connection, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then possibly not deploy.

• The airbag warning light lights up permanently or intermittently.
• The instrument cluster shows a fault message.
• The diagnostic tool does not communicate with the control unit.
• The fault memory cannot be cleared.

The light reports every defect as soon as it occurs. Take it seriously and have the system checked.
