Airbag control unit with part number 95910-2B470

What does the airbag control unit 95910-2B470 do?

As the central control unit of the restraint system (SRS) of Hyundai, the airbag control unit 95910-2B470 evaluates the signals from the crash sensors. In a collision it decides within milliseconds on the triggering of the airbags and seatbelt pretensioners. Faults in the system are reported via the airbag warning light.

While driving, the control unit monitors the entire system continuously.

After an accident it stores crash data and locks itself afterwards.

Why does the control unit 95910-2B470 fail?

The most common cause is a set of crash data stored after an accident, even if no airbag was triggered. A normal diagnostic tool does not delete it. In addition, aged electronics, cold solder joints, moisture and voltage spikes play a role in the control unit 95910-2B470.

This data remains stored in the control unit. Only during the repair by Airbag24 is it deleted.

The other causes concern the electronics themselves. Components age, solder joints can go cold, and plug connections take up moisture and corrode.

Voltage spikes, for example from a weak battery or a jump start, put additional strain on the unit.

How can you tell that the 95910-2B470 is defective?

The airbag warning light in the instrument cluster lights up on the 95910-2B470 permanently or from time to time, and an error message appears. In this case airbags and seatbelt pretensioners may possibly not trigger in an emergency.

Typical signs at a glance:

• Airbag warning light permanently or from time to time active
• Error message in the instrument cluster
• No connection from the diagnostic tool to the control unit
• Fault memory cannot be cleared

One of these signs alone justifies a check of the system.
