Airbag control unit with part number 95910-BF300

What does the airbag control unit 95910-BF300 do?

At Hyundai the airbag control unit 95910-BF300 is the control unit of the restraint system (SRS). It evaluates the signals from the crash sensors, decides in an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

It reports faults via the airbag warning light in the instrument cluster. After an accident the unit stores crash data and locks itself; the repair lifts this lock.

Why does the control unit 95910-BF300 fail?

Most often the cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Other causes are ageing components, dry solder joints, moisture at plug connections and voltage spikes.

Crash data cannot be removed with ordinary means in everyday use; Airbag24 erases it during the repair. That no airbag has deployed does not change this storage process.

Ageing electronics, dry solder joints and moisture at plug connections are among the other causes. Voltage spikes, for example from a weak battery or a jump start, can also affect the unit.

How can you tell that the 95910-BF300 is defective?

A defect on the 95910-BF300 shows up as the airbag warning light in the instrument cluster, which lights up constantly or intermittently. In addition there are fault messages, a diagnostic tool with no connection to the control unit, and a fault memory that cannot be cleared.

If the warning light comes on, the system has detected a fault. In an emergency, airbags and seatbelt pretensioners may then fail to deploy. Have the finding checked promptly, before you continue driving.
