Toyota Grand Highlander airbag control unit repair⁽¹⁾

What should I know about Toyota Grand Highlander airbag control units?

The Toyota Grand Highlander airbag control unit evaluates the crash sensors, triggers the airbags and seat belt tensioners, and monitors the entire airbag system. If the system detects a fault, the airbag warning light comes on.

After an accident, the control unit stores crash data and locks itself. Airbag24 repairs your own control unit when you send it in for repair, and in the process deletes the stored crash data.

The airbag warning light indicates a fault but does not reveal its cause. The cause should therefore be checked by a specialist workshop, because the airbag system is safety-relevant. Work on it belongs in the hands of a qualified specialist.

Which Toyota Grand Highlander generations are there?

There is one model series for the Toyota Grand Highlander: the Grand Highlander, built since 2024 and still in production.

The series can be identified by model year and part number. Please check both before sending in a control unit.

• Grand Highlander (since 2024) – the series that is still in production

How do I identify my Toyota Grand Highlander airbag control unit?

The part number on the label of the control unit determines the exact version. Together with the model year and equipment of your vehicle, it identifies the right control unit.

The following part numbers belong to the Toyota Grand Highlander. They are written exactly as listed; the list does not claim to be complete:

• Part number 89170-0E730
• Part number 89170-0E740
• Part number 89170-0E760
• Part number 89170-0E480
• Part number 89170-0E720

Examples from the fault code list for this model are B1000 (fault in the airbag control unit itself), U0151 (communication with the airbag control unit lost) and B1800 (driver airbag ignition circuit faulty). However, a single code does not prove a defect; it is only a pointer for the workshop.

What airbag equipment does the Toyota Grand Highlander have?

The Toyota Grand Highlander is fitted with several airbags, including front, side and curtain airbags. Which airbags are installed in your vehicle depends on the trim level and model year.

The protection system typically includes front airbags for driver and front passenger, front side airbags and curtain airbags that protect the occupants' heads. A driver knee airbag is provided depending on the equipment. The exact equipment is listed in the vehicle documents or the equipment list.

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

The repaired control unit returns with all vehicle data and is ready for use immediately after reinstallation — no coding or programming is necessary.
