Airbag control unit with part number 89170-06250

What does the airbag control unit 89170-06250 do?

The 89170-06250 is the airbag control unit of the restraint system (SRS) in Toyota. It monitors the crash sensors, triggers the airbags and seatbelt pretensioners in an emergency and permanently checks the condition of the system. If it detects a fault, it shows this via the airbag warning light.

In an accident it has to decide within milliseconds which restraint elements come into use. To do so, it evaluates measured values without interruption, even when the vehicle is stationary.

After an accident the unit stores crash data and locks itself. The evaluation continues in the background, so faults show up in the memory early.

Why does the control unit 89170-06250 fail?

The most common cause is crash data that remains in the unit after an accident, even if no airbag has deployed. A standard diagnostic tool cannot remove it. Other causes include ageing components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes from a weak battery or jump-starting.

The data stay in the unit even if the vehicle runs inconspicuously again after the accident. You notice nothing of this in everyday use until the warning light shows something.

Ageing electronic components become harder to keep under control over time. Solder joints that have gone cold, and plug connections where moisture or salt cause corrosion, are also possible causes.

Voltage spikes occur, for example, when the battery is weakening or when a vehicle is started with jump leads. Such load changes disturb the electronics.

How can you tell that the 89170-06250 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message may appear in the instrument cluster. If the diagnostic tool cannot connect to the control unit, or the fault memory cannot be cleared, this is a further sign of a fault. In that state, airbags and seatbelt pretensioners may not be able to trigger in an emergency.

The warning light is the clearest hint the vehicle gives. It is the system's own signal, not a decorative element on the dashboard.

If you ignore the signal, you drive with a restraint system whose function has not been confirmed.

Comparing the part number on the label with this page confirms that you have the correct control unit in front of you. That comparison says no more than this. Still, have the fault memory read out beforehand, because only this result shows whether the control unit itself is defective or a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 89170-33430, 89170-33470, 89170-33530.

How does the repair of the 89170-06250 work?

You read out the fault memory first and enclose the log. Then disconnect the battery and only afterwards remove the control unit. Next, create a repair order online and pack the unit well before you send it. Airbag24 inspects the unit, repairs defective components and tests it; processing at Airbag24 usually takes 3–4 working days.

The sequence serves your safety, which is why the steps follow in exactly this order. Only once the memory is secured and the battery is disconnected do you remove the control unit from the vehicle.

At Airbag24 the work begins with inspection on the test bench. Afterwards, defective components are repaired, the stored crash data is erased and a function test is carried out. Only then does the unit go 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 89170-06250 get to Airbag24?

Either you hand the control unit in as a parcel, or you commission a UPS collection for an extra charge. After the repair, Airbag24 sends the unit back to you by UPS.

Place the printed repair order in the parcel. Pack the control unit shockproof before you send it.
