Airbag control unit with part number 95910-B4000

What does the airbag control unit 95910-B4000 do?

The airbag control unit 95910-B4000 manages the restraint system (SRS) in Hyundai. It evaluates the crash sensors, selects in an accident within milliseconds which airbags and seatbelt pretensioners to trigger, and monitors the system throughout.

Messages from the system converge in the control unit and appear via the airbag warning light. After an accident it stores crash data and locks itself.

Why does the control unit 95910-B4000 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. In the control unit 95910-B4000, aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes come on top of that.

A normal diagnostic tool does not erase this data.

Electronic components change with use, and solder joints can be damaged. Moisture and corrosion attack plug connections.

Voltage spikes occur, for example, with a weak battery or when starting with a jump start.

How can you tell that the 95910-B4000 is defective?

The airbag warning light is the most important sign of a defect in the 95910-B4000. It lights up constantly or intermittently, and in addition there are fault messages in the instrument cluster and a fault memory that cannot be cleared.

The following signs can occur with a defect:

• Warning light stays on constantly
• Warning light flashes or lights up only intermittently
• Fault message in the instrument cluster
• Diagnostic tool cannot reach the control unit
• Fault memory remains when clearing is attempted

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. Please have such signs checked promptly.
