Toyota Proace City airbag control unit repair⁽¹⁾

What should I pay attention to with Toyota Proace City airbag control units?

The airbag control unit evaluates the crash sensors, triggers the airbags and belt tensioners, and monitors the entire airbag system. If it detects a fault, the airbag warning light comes on in the dashboard. After an accident, the unit stores crash data and locks itself.

The Toyota Proace City has been offered since 2019. The control unit continuously checks the airbag system and stores detected faults in the fault memory, which a workshop can read out.

Airbag24 repairs your own control unit that you send to us. After an accident, deleting the stored crash data is part of the repair. Work on the airbag system belongs in the hands of a specialist workshop. Improper handling by non-specialists can impair the function of the system.

Which Toyota Proace City generations are there?

For the Toyota Proace City, our shop lists the K9 generation, which has been built since 2019. Whether a control unit fits your vehicle depends first on this generation.

The Toyota Proace City has been available in Europe since 2019. The generation carries the code K9 and is still being built. Within one generation, control unit versions can differ.

• K9 (since 2019) – the generation that is still being built

The repair in our shop is intended for the control unit of the Toyota Proace City K9. Please therefore first check whether your vehicle belongs to this generation.

How do I identify my Toyota Proace City airbag control unit?

The part number on the label of the control unit determines the exact version. In addition, check the year of manufacture and equipment of your Toyota Proace City before sending in the unit.

The label is the most important reference, because it shows which version is installed. The vehicle identification number (VIN) and the year of manufacture help to assign the control unit clearly to your vehicle.

Examples of fault codes mentioned in connection with this control unit:

• B1000: fault in the airbag control unit (centre sensor unit), internal fault
• U0151: communication with the airbag control unit lost
• B1800: driver airbag ignition circuit faulty (short circuit)

A fault code alone does not prove a defect. Only an inspection in a workshop shows whether the control unit itself is the cause or another component is.

What airbag equipment does the Toyota Proace City have?

Driver and front passenger airbags are part of the Toyota Proace City's equipment. Side airbags and head airbags (curtain airbags) depend on the equipment line and version.

Which airbags are fitted in your vehicle is shown in its factory equipment list. The control unit coordinates all fitted airbags and is therefore the central element of the system.

The route to repair works like this: have the fault memory read out by a specialist workshop. The workshop disconnects the battery and removes the control unit. You then create a repair order online and send the unit to us by parcel.

Processing usually takes 3–4 working days: checking, repairing and testing.

The repaired control unit comes back with all vehicle data and is ready for use immediately after refitting — coding or programming is not necessary.
