Airbag control unit with part number 95910-2W200

What does the airbag control unit 95910-2W200 do?

The airbag control unit 95910-2W200 coordinates the restraint system (SRS) for Hyundai. It reads the signals from the crash sensors, works out in an emergency in the blink of an eye which airbags and seatbelt pretensioners to trigger, and checks the entire system continuously.

If the unit detects a fault, it switches on the airbag warning light in the instrument cluster. This lets you notice a fault straight away, without a workshop test.

After an accident the unit stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit 95910-2W200 fail?

Stored crash data is the most common cause: it remains in the control unit after an accident, even without an airbag deploying, and an ordinary diagnostic tool cannot erase it. Ageing components, cold solder joints, moisture with corrosion at plug connections and voltage spikes are also possible.

Ageing and solder joints deteriorate slowly, and a fault only becomes noticeable once a contact really gives way. Voltage spikes, by contrast, occur suddenly, for example with a weak battery or when jump-starting.

Whether a unit suffers from any of these points only becomes clear during the test on the test bench. Before the repair, the fault memory always comes first, because it provides the clue to the cause.

How can you tell that the 95910-2W200 is defective?

Typical signs are an airbag warning light in the instrument cluster that stays on permanently or intermittently, a fault message in the instrument cluster, a diagnostic tool without a connection to the control unit, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then possibly not deploy.

• warning light stays on permanently or intermittently
• message in the instrument cluster about the airbag system
• diagnostic tool cannot establish a connection to the control unit
• fault memory remains despite an attempt to clear it

As soon as the light is visible, a test makes sense. The warning light is the signal you should react to.

Compare the part number on the label of the removed unit with this page; that only confirms that it is the correct unit. Also have the fault memory read out beforehand, because this log shows whether the control unit itself is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 95700-2B110, 95910-0W100, 95910-26100, 95910-2B028, 95910-2B900, 95910-2B970.

How does the repair of the 95910-2W200 work?

First read out the fault memory and attach the log. Then disconnect the battery, remove the control unit and create a repair order online before sending in the well-packed unit. Airbag24 checks it, replaces defective components, deletes the crash data and runs a function test; the unit then goes back to you.

Processing at Airbag24 usually takes 3–4 working days. This time frame covers only checking, repairing and testing at Airbag24.

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.
