Airbag control unit with part number 89170-06411

What does the airbag control unit 89170-06411 do?

The airbag control unit 89170-06411 coordinates the restraint system (SRS) for Toyota. It evaluates the signals from the crash sensors, decides within a fraction of a second in an impact whether airbags and seatbelt pretensioners are triggered, and checks the entire system continuously.

If the unit detects a fault, it reports it via the airbag warning light in the instrument cluster. This monitoring works independently of whether you are using the vehicle at the time.

After an accident it stores crash data and locks itself. This process is part of the system's design; in everyday use you notice nothing of it.

Why does the control unit 89170-06411 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; they cannot be erased with a normal diagnostic tool. Other causes in general are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

Reading out the fault memory quickly clarifies whether such data is stored in the unit.

Ageing components and cold solder joints show up over time, moisture slowly attacks plug connections, and voltage spikes can occur at any moment.

How can you tell that the 89170-06411 is defective?

The airbag warning light in the instrument cluster stays on continuously or intermittently, an error message appears in the instrument cluster, the diagnostic tool receives no connection to the control unit, or the fault memory cannot be cleared. In an emergency, the airbags and seatbelt pretensioners may then not deploy.

React to the warning light immediately rather than ignoring the indicator.

A diagnostic tool without a connection is also a sign that needs checking. Whether the cause lies in the control unit or in the connection to it only becomes clear from the readout.

On the one hand, compare the part number on the label of the removed unit with this page; this only confirms that it is the right unit. On the other hand, have the fault memory read out beforehand, because only the result shows whether the control unit itself or a plug or cable is the cause.

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 89170-06411 work?

First have the fault memory read out and attach the log. Then disconnect the battery and only after that remove the control unit. Next create a repair order online, pack the unit well and send it in. At Airbag24, testing, repair and function test usually take 3–4 working days.

This order is important for your safety, because removing the unit without disconnecting the battery involves risk.

At Airbag24 the unit is checked on the test bench. Defective components are repaired or replaced, stored crash data is erased, and a function test completes the work. Afterwards your own unit goes back to you.

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 89170-06411 get to Airbag24?

You send the unit as a parcel or book a UPS collection for an extra charge, and after the repair Airbag24 returns it by UPS. The printed repair order belongs in the parcel, and the unit must be packed shockproof.

A sturdy box with padding protects the control unit reliably on the way.
