Hyundai H350 airbag control unit repair⁽¹⁾

What should I pay attention to with Hyundai H350 airbag control units?

The Hyundai H350 airbag control unit evaluates the signals from the crash sensors, triggers the airbags and belt tensioners, and reports faults via the airbag warning light. After an accident it stores crash data and locks itself. Airbag24 repairs the control unit you send in.

The control unit is the central evaluation unit of the airbag system. It monitors the connected components in the vehicle and decides in an emergency which airbags and belt tensioners are triggered. A stored fault lights up the airbag warning light in the instrument cluster.

A fault indication does not automatically mean that the control unit is defective. Only reading out the fault memory shows whether a repair is needed. It is also important to know that after a deployment, crash data is stored in the unit and is erased during the repair.

Which Hyundai H350 generations are there?

The Hyundai H350 is listed as one model series: the H350, built from 2015 to 2019. It is a van that was also offered in Germany.

• H350 (from 2015 to 2019) – van of this series, built from 2015 to 2019.

An exact match cannot be made from the name alone. Build year, market and trim level can determine the variant fitted; the part number on the unit is the most important reference.

How do I identify my Hyundai H350 airbag control unit?

The part number on the label of the control unit determines which version is fitted. The build year and equipment of your vehicle should also be taken into account.

For the Hyundai H350 this part number is known:

• 95910-59000

The number is usually found on a label on the housing of the control unit. Compare it with the unit before you send it in.

Fault codes such as B1620, B1651 or B1101 can appear in the fault memory. B1620 indicates an internal fault in the control unit, B1651 a stored crash with the driver's front airbag triggered, and B1101 a supply voltage that is too high. A single fault code does not prove a defect, however; it only shows what the system has registered.

What airbag equipment does the Hyundai H350 have?

According to the manufacturer, the equipment of the Hyundai H350 includes front airbags for the driver and front passenger. Whether further airbags are fitted depends on the market and trim level.

Which further modules your vehicle has is shown most reliably by the manufacturer's information for the vehicle identification number (VIN). Side, head or knee airbags cannot be stated generally for the H350; they depend on the vehicle.

The airbag system is safety-relevant. If you are unsure, a specialist workshop should carry out the removal.

The repair runs as follows: have the fault memory read out. Disconnect the battery before removing the control unit, then remove it. Create a repair order online and send in the unit. Processing usually takes 3–4 working days: checking, repairing and testing.

The repaired control unit returns with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
