Airbag control unit with part number 95910-2S650

What does the airbag control unit 95910-2S650 do?

The unit 95910-2S650 is the control unit of the restraint system (SRS) for vehicles from Hyundai. It processes the signals from the crash sensors, decides in an accident within milliseconds on the deployment of airbags and seatbelt pretensioners, and monitors the system continuously.

It checks constantly whether sensors, wiring and trigger units are working. If it detects a fault, it creates an entry in the fault memory.

An accident leads to the storage of crash data, after which the control unit locks itself.

Why does the control unit 95910-2S650 fail?

The most common cause is crash data stored after an accident, even if no airbag was deployed; a normal diagnostic tool cannot remove them from the memory. Aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes are also involved.

Electronic components change over time and can then fail.

Cold solder joints and moisture on plug connections lead to contact faults that show up only intermittently.

Voltage spikes arise, for example, from a weak battery or a jump-start and can impair the unit.

How can you tell that the 95910-2S650 is defective?

A defect shows itself in the airbag warning light in the instrument cluster, which lights up constantly or only intermittently. In addition there are error messages in the instrument cluster, no connection of the diagnostic tool to the control unit, or a fault memory that cannot be cleared; then airbags and seatbelt pretensioners may not deploy in an emergency.

The warning light is the clearest sign a vehicle gives for this. However, it does not explain the cause on its own.

A read-out checks the fault memory. Only then is it clear whether the control unit or another component is affected.

Which vehicles is the 95910-2S650 fitted in?

A fixed vehicle assignment exists for this part number. The control unit 95910-2S650 is fitted in these vehicles: Hyundai ix35 LM (2009-2013) and LM Facelift (2013-2015).

In detail, the list looks like this:

• Hyundai ix35 LM (2009-2013)
• Hyundai ix35 LM Facelift (2013-2015)

Comparing the part number with the label of the removed unit shows whether it is the correct unit. It makes no statement about the defect. For that reason, have the fault memory read out in advance, because only this record shows whether the control unit itself is affected or whether a connector or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 95910-2S000, 95910-2S100, 95910-2S150, 95910-2S200, 95910-2S250, 95910-2S350.

How does the repair of the 95910-2S650 work?

Have the fault memory read out, attach the log, then disconnect the battery and only then remove the control unit; afterwards create the repair order online and send in the packed unit. Processing at Airbag24 usually takes 3–4 working days.

This sequence is mandatory for safety reasons.

At Airbag24 the unit is examined on the test bench. Defective components are replaced, stored crash data are erased and a function test is carried out. Afterwards the repaired unit comes back to you.

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.

How does the control unit 95910-2S650 get to Airbag24?

You can send the unit to Airbag24 as a parcel, or book a UPS collection for an extra charge. The return shipment after the repair is made by UPS.

Enclose the printed repair order with the parcel. Pack the control unit so that it is shockproof during transport.
