Airbag control unit with part number 95910-2B200

What does the airbag control unit 95910-2B200 do?

The airbag control unit 95910-2B200 is the central control unit of the restraint system (SRS) for Hyundai. It reads the crash sensor signals and decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered.

It also monitors the system continuously. Faults are indicated via the airbag warning light, and after an accident it stores crash data and locks itself.

Why does the control unit 95910-2B200 fail?

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

Crash data remains in the memory and cannot be removed with a normal diagnostic tool. This is why the fault persists even when the rest of the technology appears unremarkable.

Aged components, cold solder joints and corrosion are among the general causes that are conceivable for any control unit.

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

How can you tell that the 95910-2B200 is defective?

Typical signs are the airbag warning light, which lights up permanently or intermittently, and a fault message in the instrument cluster. In addition there is no connection to the diagnostic tool, and the fault memory remains. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

• Airbag warning light in the instrument cluster, permanent or intermittent
• Fault message in the instrument cluster display
• Diagnostic tool does not find the control unit
• Fault memory remains, even after an attempt to clear it

These signs cannot be ignored. A prompt check will clarify the cause.
