Airbag control unit with part number 95910-H6400

What does the airbag control unit 95910-H6400 do?

The airbag control unit 95910-H6400 is the central control unit of the restraint system (SRS) for Hyundai. It evaluates the signals from the crash sensors, decides within milliseconds in an accident whether to trigger, and monitors the system continuously.

If the unit detects a fault, it reports it via the airbag warning light in the instrument cluster. The sensors supply only measured values; the decision is taken by the control unit itself.

After an accident, it stores crash data and locks itself. The sections that follow describe the causes and signs of a failure.

Why does the control unit 95910-H6400 fail?

The most common cause for the 95910-H6400 is crash data stored after an accident, even if no airbag has fired. Other causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data stays in the memory, and a normal diagnostic tool cannot erase it. Airbag24 removes it during the repair.

Apart from the crash data, the following causes may be involved:

• Ageing electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or a jump start

How can you tell that the 95910-H6400 is defective?

The airbag warning light in the instrument cluster stays on continuously or intermittently, an error message appears in the instrument cluster, the diagnostic tool gets no connection to the control unit 95910-H6400, and the fault memory cannot be cleared.

The warning light indicates that the control unit has detected a fault. As long as it is lit, airbags and seatbelt pretensioners may possibly not deploy in an emergency.

A lack of connection to the diagnostic tool can also be caused by a plug or a cable rather than by the unit itself. Only reading out the fault memory shows this.
