Toyota Avensis Verso airbag control unit repair⁽¹⁾

What should be considered with Toyota Avensis Verso airbag control units?

The airbag control unit of the Toyota Avensis Verso evaluates the signals from the crash sensors and decides in an emergency whether the airbags are triggered. It monitors the entire airbag system and reports faults via the airbag warning light. Airbag24 repairs the control unit you send in.

The control unit is a central component of the restraint system in the vehicle. It continuously checks the sensors, the firing circuits and the connections to the airbag modules. If it detects a fault, it stores the fault in the fault memory, and the warning light in the instrument cluster stays on.

After an accident, the control unit stores crash data and locks itself. This condition should be checked by a specialist workshop, because the airbag system is safety-relevant. At Airbag24, the crash data is erased, the electronics are repaired and the unit is tested before it is sent back. Do not carry out any work on the airbag system yourself.

Which Toyota Avensis Verso generations are there?

The Toyota Avensis Verso was built in two series: the XM20 from 2001 to 2003 and the XM20 Facelift from 2003 to 2005. The model year of your vehicle shows which series it belongs to.

The Avensis Verso is the seven-seat van version of the Avensis. The first series, the XM20, came onto the market in 2001. The facelift from 2003 revised the model, so the control unit and the equipment may differ from the predecessor.

• XM20 (2001–2003) – first series of the model line
• XM20 Facelift (2003–2005) – revised series after the facelift

Assigning the series matters because airbag control units can differ between model years. Check the model year and the part number before sending in the unit.

How do I identify my Toyota Avensis Verso 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 should also be stated. The following part numbers are listed for this model series.

The part number is the most important reference for identification and is usually printed on the label of the unit. Together with the model year and the vehicle identification number (VIN) of your vehicle, the matching version can be determined.

• 89170-44040 (part number)
• 89170-44050 (part number)
• 89170-44060 (part number)

This list does not claim to be complete. Typical fault codes are B1800 (driver airbag firing circuit faulty, short circuit), B1805 (passenger airbag firing circuit faulty, short circuit) and U0151 (communication with the airbag control unit lost). A single fault code does not prove a defect. Only an inspection in a workshop shows whether the control unit is affected.

What airbag equipment does the Toyota Avensis Verso have?

The Avensis Verso came with several airbags as standard equipment. How many airbags your vehicle has depends on the model year and trim level. Check the equipment of your own vehicle before the repair.

According to test reports, several airbags were part of the standard equipment. One test for the 2004 model year lists six airbags. The exact number and arrangement may vary by market and trim level.

The airbags are controlled by the control unit, which coordinates their deployment in a collision. For the repair it is therefore important that the unit matches your series and is fully tested.

First have the fault memory read out. A specialist workshop then removes the control unit, which includes disconnecting the battery. You then create a repair order online at Airbag24 and send the unit in by parcel. Processing usually takes 3–4 working days: we check, repair and test the unit.

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