Airbag control unit with part number 95910-B8500

What does the airbag control unit 95910-B8500 do?

The airbag control unit 95910-B8500 controls the restraint system (SRS) of Hyundai. It processes the signals from the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and checks the system continuously for faults.

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

Why does the control unit 95910-B8500 fail?

The most common cause is stored crash data from an earlier accident, even if no airbag has deployed. Other causes include aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

Crash data cannot be erased with a normal diagnostic tool. Airbag24 removes it during the repair.

The other causes are general in nature: electronics age, plug connections are susceptible to moisture, and voltage spikes can stress components. Which of them applies to your unit is shown only by the test.

How can you tell that the 95910-B8500 is defective?

Typical signs on the 95910-B8500 are an airbag warning light in the instrument cluster that lights up permanently or intermittently, fault messages in the instrument cluster, no connection from the diagnostic tool to the control unit, and a fault memory that cannot be cleared.

• Airbag warning light in the instrument cluster
• Fault message in the instrument cluster
• Diagnostic tool finds no connection
• Fault memory cannot be cleared

If you notice any of these signs, airbags and seatbelt pretensioners may possibly fail to deploy in an emergency. Therefore take these warnings seriously.
