Airbag control unit with part number 95910-2S250

What does the airbag control unit 95910-2S250 do?

The airbag control unit 95910-2S250 controls the restraint system (SRS) of Hyundai. It evaluates the crash sensors and decides in an impact, within milliseconds, which airbags and seatbelt pretensioners are triggered.

The unit constantly checks the system's components. If it detects a fault, it shows this via the airbag warning light in the instrument cluster.

After an accident the control unit stores crash data and locks itself. The lock is only lifted by the repair.

Why does the control unit 95910-2S250 fail?

Crash data stored in the 95910-2S250 after an accident is the most common cause, even if no airbag has been triggered. Other causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Stored crash data cannot be cleared with a normal diagnostic tool. Airbag24 clears it during the repair.

The other causes affect the electronics themselves or their connections. Voltage spikes arise, for example, with a weak battery or a jump start.

How can you tell that the 95910-2S250 is defective?

On the 95910-2S250, a defect is recognised by the airbag warning light in the instrument cluster, which lights up permanently or intermittently. A fault message may also be present, along with no contact to the diagnostic tool and a fault memory that cannot be cleared.

These signs occur singly or together:

• Airbag warning light on permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

Airbags and seatbelt pretensioners may possibly not deploy in an emergency while these signs are present. A defect should therefore not be ignored.
