Airbag control unit with part number 95910-G2300

What does the airbag control unit 95910-G2300 do?

The airbag control unit 95910-G2300 is the central control unit of the restraint system (SRS) for Hyundai. It evaluates the signals of the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners to trigger, and monitors the system continuously. After an accident, it stores crash data and locks itself.

The control unit continuously checks the connections to the sensors, the airbags and the seatbelt pretensioners. If it detects a fault, it creates an entry in the fault memory and shows the fault via the airbag warning light in the instrument cluster.

Because the decision in an emergency has to be made so quickly, this ongoing self-check is an essential part of the function. It runs throughout operation, not only in an accident.

Why does the control unit 95910-G2300 fail?

Most often the cause lies in crash data that the unit has stored after an accident, even if no airbag has triggered; a standard diagnostic tool cannot erase them. Other possible causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The entry remains in the unit even if no airbag has triggered. That is why, for faults after an accident, it is the first place to start.

• ageing electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

Which of these causes applies in an individual case is shown only by an examination of the unit. Airbag24 tests the unit on the test bench for this purpose.

How can you tell that the 95910-G2300 is defective?

A defect on the 95910-G2300 shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently, and as a fault message in the instrument cluster. In addition, the diagnostic tool has no connection to the control unit, and the fault memory cannot be cleared.

The warning light is the control unit's direct indication of a fault in the restraint system, not a chance finding. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

If you see one of these indications, it is worth having the fault memory read out before taking any further steps.

Which vehicles is the 95910-G2300 fitted in?

The airbag control unit 95910-G2300 is fitted in these vehicles: Hyundai Ioniq AE Facelift (2019-2022) and AE (2016-2019).

The assignment comes from our data for this part number. The overview looks like this:

• Hyundai Ioniq AE Facelift (2019-2022)
• Hyundai Ioniq AE (2016-2019)

On the one hand, a comparison helps: check the part number on the label of the removed unit against this page. That only ensures it is the right unit. On the other hand, have the fault memory read out before removal. Only this log shows whether the control unit itself 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-G2000, 95910-G2400, 95910-G2500, 95910-G7400, G7959-10400.

How does the repair of the 95910-G2300 work?

First you read out the fault memory and enclose the log, then you disconnect the battery and only then remove the control unit 95910-G2300. Next, you create a repair order online and send the unit in well packed. Airbag24 usually needs 3–4 working days for testing, repairing and checking.

Airbag24 tests the unit on the test bench, replaces defective components, erases stored crash data and runs a function test. Your own unit is then sent 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-G2300 get to Airbag24?

You send the control unit 95910-G2300 to Airbag24 as a parcel or have it collected by UPS for an extra charge. Airbag24 then returns the repaired unit by UPS.

The printed repair order goes into the parcel. Pack the unit shock-resistant so that it arrives undamaged.
