Airbag control unit with part number 89170-06750

What does the airbag control unit 89170-06750 do?

The airbag control unit 89170-06750 is the central control unit of the restraint system of Toyota. It processes the measured values from the crash sensors, selects the appropriate airbags and seatbelt pretensioners in a crash, and triggers them within fractions of a second.

During operation, the unit checks the system continuously. If it detects a fault, the airbag warning light in the instrument cluster lights up.

After a crash, the unit stores crash data and locks itself. The further sections show how this affects diagnosis and repair.

Why does the control unit 89170-06750 fail?

Most often, the cause is crash data stored after a crash, even if no airbag has triggered. Aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are added to this.

A normal diagnostic tool cannot remove this data.

The other causes affect the electronics themselves. Voltage spikes arise, for example, from a weak battery or when starting with a jump start.

Moisture and corrosion mainly attack the plug connections through which the control unit is connected to the vehicle.

How can you tell that the 89170-06750 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message appears in the instrument cluster. The diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then not trigger.

The light therefore indicates the defect, regardless of how inconspicuously the vehicle otherwise runs.

If the light cannot be reset or returns, have the fault memory read out. The readout log shows which message the control unit has stored.

Which vehicles is the 89170-06750 fitted in?

The control unit 89170-06750 is fitted in these vehicles: Toyota Camry XV50 (2011-2019).

The vehicles we assign to this number are:

• Toyota Camry XV50 (2011-2019)

Compare the part number on the label of the removed unit with this page. This only shows whether it is the right unit. Have the fault memory read out as well. The result shows whether the control unit is defective or whether a plug or a cable is behind the fault.

For the same vehicles, we also repair control units with the part numbers 150800-2310, 89170-06670, 89170-06671, 89170-06770.

How does the repair of the 89170-06750 work?

First have the fault memory read out and enclose the readout log, then disconnect the battery and only then remove the control unit. Online, you create a repair order and send in the well-packed unit. Airbag24 checks it on the test bench, replaces defective components, erases stored crash data and carries out a function test; processing usually takes 3–4 working days.

The sequence follows a fixed order because safety requires it. Removal does not begin without the battery disconnected.

In the end, you receive your own unit back.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 89170-06750 get to Airbag24?

You hand the unit to a parcel service, or alternatively UPS collects it from you for an extra charge. After the repair, Airbag24 brings it back to you by UPS.

Pack the unit shock-proof and enclose the printed repair order.
