Airbag control unit with part number 95910-CH670

What does the airbag control unit 95910-CH670 do?

The airbag control unit 95910-CH670 controls the restraint system (SRS) for Hyundai. It continuously checks the crash sensors and their connections, decides in a crash within milliseconds which airbags and seatbelt pretensioners are triggered, and reports faults via the airbag warning light.

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

The control unit is therefore the link between the sensors and the restraint devices in the vehicle.

Why does the control unit 95910-CH670 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Other causes include ageing components, moisture and corrosion at plugs, and voltage spikes, for example from a weak battery or a jump start.

• Crash data that cannot be erased with an ordinary diagnostic tool
• Ageing electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or a jump start

Airbag24 erases the crash data during the repair. Airbag24 narrows down the other causes on the test bench.

How can you tell that the 95910-CH670 is defective?

Look out for an airbag warning light that stays on permanently or intermittently, error messages in the instrument cluster, no connection to the diagnostic tool, or a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

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

Each of these signs is an independent indication. Have it checked so that the cause becomes clear.

Compare the part number on the label of the removed unit with this page, so that you know you have the right unit. Also have the fault memory read out beforehand. Only this log shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 28394001, 95910-2S750, 95910-CZ000, 95910-D7130, 959102S850, A3C03656003.

How does the repair of the 95910-CH670 work?

You read out the fault memory first and attach the log. Then you disconnect the battery, remove the control unit and create a repair order online before sending in the well-packed unit.

This order is a safety measure. The battery is disconnected before removal, not afterwards.

Airbag24 tests the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test. Your own unit then goes back to you. Processing at Airbag24 usually takes 3–4 working days.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
