Airbag control unit with part number 89170-60461

What does the airbag control unit 89170-60461 do?

The airbag control unit 89170-60461 centrally controls the restraint system (SRS) of Toyota. From the signals of the crash sensors it calculates within milliseconds which airbags and seatbelt pretensioners fire. It also monitors all components continuously and indicates faults via the airbag warning light.

During operation the control unit continuously checks its components and connections. It stores any irregularities in the fault memory, which a workshop or a diagnostic tool can read out.

After a crash, it stores crash data and locks itself.

Why does the control unit 89170-60461 fail?

The most common cause is crash data stored after an accident, even if no airbag has fired. A standard diagnostic tool cannot erase this data. Other causes include ageing electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes, for example from a weak battery or a jump start.

Ageing components lose reliability over time. Corrosion on a plug contact changes the transition resistance and can thus trigger a fault.

Voltage spikes are brief, but they can damage electronics. It is therefore worth checking the battery before diagnosis.

How can you tell that the 89170-60461 is defective?

A defect shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Fault messages in the instrument cluster, no connection to the diagnostic tool and a fault memory that cannot be cleared also point to a defect. In that case, airbags and seatbelt pretensioners may possibly fail to fire in an emergency.

• Airbag warning light lights up permanently or intermittently
• Fault message in the instrument cluster
• No connection between diagnostic tool and control unit
• Fault memory cannot be cleared

A warning of this kind should be taken seriously. The warning light reports the finding immediately and affects the entire restraint system.

First, a comparison helps: compare the part number on the label of the removed unit with this page. This only confirms that it is the correct unit. Also have the fault memory read out, because only the log shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 150300-2965, 89170-60540, 89170-60630, 89170-60631.

How does the repair of the 89170-60461 work?

First have the fault memory read out and attach the log, then disconnect the battery before removing the control unit. Next, create a repair order online and pack the unit well before you send it in. Airbag24 tests the unit on the test bench, repairs it, erases stored crash data and tests the function.

The unit then goes back to you. The order is important for safety during removal.

Airbag24 usually needs 3–4 working days, and this time covers only testing, repairing and function testing. In doing so, Airbag24 replaces defective components. 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 89170-60461 get to Airbag24?

You send the unit as a parcel to Airbag24 or book a UPS collection for an extra charge. After the repair, Airbag24 returns it by UPS.

The printed repair order goes into the parcel. Pack the unit shock-proof.
