Airbag control unit with part number 95910-2W890

What does the airbag control unit 95910-2W890 do?

The airbag control unit 95910-2W890 is the central control unit of the restraint system (SRS) for Hyundai. It measures what happens in an accident through the crash sensors and selects, within milliseconds, the airbags and seatbelt pretensioners to be triggered.

It also monitors the system components permanently and shows faults via the airbag warning light.

After an accident, it stores crash data and locks itself.

Why does the control unit 95910-2W890 fail?

The most common cause with the 95910-2W890 is crash data stored after an accident, even if no airbag has deployed. Other causes are ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Such crash data cannot be erased with a standard diagnostic tool. Airbag24 removes it as part of the repair.

Ageing electronics and cold solder joints can cause faults. Moisture, corrosion and voltage spikes act on the same electronics, for example with a weak battery or when starting with jump leads.

How can you tell that the 95910-2W890 is defective?

A fault in the 95910-2W890 shows up through the airbag warning light in the instrument cluster, an error message, a missing connection to the diagnostic tool, or a fault memory that cannot be cleared.

The airbag warning light in the instrument cluster either stays on permanently or lights up only intermittently. An error message may also appear, and the diagnostic tool may then be unable to connect to the control unit.

If the fault memory cannot be emptied, this is also a finding. Airbags and seatbelt pretensioners may then possibly not trigger in an emergency, which is why a check is important.
