Airbag control unit with part number 95910-K7750

What does the airbag control unit 95910-K7750 do?

The airbag control unit 95910-K7750 controls the restraint system (SRS) in Hyundai and evaluates the signals from the crash sensors. In an accident, it decides within milliseconds which airbags and seatbelt pretensioners fire. It also monitors the entire system continuously and indicates faults via the airbag warning light.

During operation the unit checks sensors, wiring and firing circuits continuously. Irregularities end up in the fault memory.

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

Why does the control unit 95910-K7750 fail?

The most common cause is crash data stored after an accident, even if no airbag has fired, and a standard diagnostic tool cannot erase it. Other causes are ageing components, corrosion on plug connectors and voltage spikes.

The other causes in detail:

• Ageing electronic components that lose reliability over time
• Cold solder joints that are barely visible from the outside
• Moisture and corrosion on plug connectors
• Voltage spikes, for example from a weak battery or a jump start

The crash data remains in the memory even when the vehicle drives normally again after the accident. That is why the accident always belongs in the fault finding.

How can you tell that the 95910-K7750 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, as soon as the unit detects a fault. In addition there are fault messages in the instrument cluster, a diagnostic tool without connection to the control unit and a fault memory that cannot be cleared. In that case, airbags and seatbelt pretensioners may possibly fail to fire in an emergency.

The warning light affects the entire restraint system and is therefore a reason for a prompt check.

If the fault memory cannot be read out, the cause remains open and must be specifically searched for.

Compare the part number on the label of the removed unit with this page, because that confirms it is the correct unit. Have the fault memory read out beforehand. Only the 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 95910-K7250.

How does the repair of the 95910-K7750 work?

First have the fault memory read out and attach the log, then disconnect the battery and only then remove the control unit. Then create a repair order online and send in the well-packed unit. Processing at Airbag24 usually takes 3–4 working days.

Airbag24 tests the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test. The unit then goes back to you.

The order is for safety during removal, and the processing time covers only testing, repairing and function testing. 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-K7750 get to Airbag24?

You send the unit as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns it by UPS.

The printed repair order goes into the parcel, and you pack the unit shock-proof.
