Airbag control unit with part number 95910-2B170

What does the airbag control unit 95910-2B170 do?

The airbag control unit 95910-2B170 coordinates the restraint system for Hyundai. It evaluates the crash sensors, decides on airbags and seatbelt pretensioners in an impact, and monitors the system continuously.

The unit detects faults in the system and reports them via the airbag warning light in the instrument cluster. The control unit works together with other components whose condition it constantly checks.

In an accident it stores crash data and locks itself.

Why does the control unit 95910-2B170 fail?

Stored crash data is the most common cause of a failure of the 95910-2B170, even if no airbag has deployed. Aged components, cold solder joints, moisture and corrosion, and voltage spikes also play a role.

Stored crash data arises in the control unit itself after an accident. It remains there even if none of the airbags has deployed, and it cannot be removed with a standard diagnostic tool.

The other causes mainly concern the electronics and their connections. Components age, solder joints can turn cold, and moisture attacks the plug contacts. Voltage spikes, for example from a weak battery or a jump start, additionally stress the circuit.

How can you tell that the 95910-2B170 is defective?

You can recognise a defect in the 95910-2B170 by the airbag warning light in the instrument cluster, by error messages there, and by a diagnostic tool that makes no contact. A fault memory that cannot be cleared is a further sign.

• Airbag warning light lights up permanently or intermittently
• Error message in the instrument cluster
• No connection of the diagnostic tool to the control unit
• Fault memory cannot be cleared

With such a finding, airbags and seatbelt pretensioners may not deploy in an emergency. The warning light is therefore not a sign that you should postpone.
