Kia EV2 airbag control unit repair⁽¹⁾

What should I pay attention to with Kia EV2 airbag control units?

The Kia EV2 airbag control unit evaluates the crash sensors, triggers the airbags and belt tensioners in an emergency, and monitors the entire restraint system. If it detects a fault, the airbag warning light in the instrument cluster comes on. Airbag24 repairs your own control unit.

After an accident, the control unit stores crash data and locks itself. At Airbag24, this crash data is erased as part of the repair. The airbag warning light should therefore not be ignored.

The airbag system is safety-relevant. Do not work on the airbag system yourself; have a specialist workshop carry out the work. Whether a particular fault can be repaired only becomes clear once the submitted unit has been examined.

Which Kia EV2 generations are there?

So far, one Kia EV2 generation is on record. The 1st generation has been built since 2026 and is still in production.

The generation can be determined from the model year and the vehicle identification number (VIN). These details show which series your vehicle belongs to. The Kia EV2 is an electric vehicle; for matching the control unit, the series is what counts.

• 1st generation (since 2026) – the series on record so far, still being built

How do I identify my Kia EV2 airbag control unit?

The part number on the label of the control unit determines the exact version. The model year and equipment of your vehicle are also important.

Note the part number, model year and vehicle identification number (VIN) before you create a repair order online. A photo of the label helps you copy the number correctly. The part number is a key reference, because it indicates the variant of the control unit.

Examples of fault codes for this model are B1650 (frontal crash stored in the control unit), B1101 (supply voltage of the airbag control unit too high) and U0151 (communication with the restraint control unit lost). A single code does not prove a defect, however. This information serves as orientation and does not replace a diagnosis in the workshop. Only examining the unit reveals the cause.

What airbag equipment does the Kia EV2 have?

According to the manufacturer, the Kia EV2 comes with seven airbags as standard. The control unit coordinates their deployment in an emergency.

According to Kia, standard equipment includes one centre airbag at the front, two front airbags, two side airbags and two curtain airbags. The passenger airbag can be deactivated, according to the manufacturer. Differences by market and trim level are possible. For the system to work in an emergency, the control unit must be fully functional.

The route to repair: first have the fault memory read out. A specialist workshop then disconnects the battery and removes the airbag control unit. You then create a repair order online and send the well-packed unit by parcel to Airbag24. Processing usually takes 3–4 working days (checking, repairing, testing).

The repaired control unit returns with all vehicle data and is ready for use as soon as it is refitted — coding or programming is not required.
