Airbag control unit with part number 89170-02P60

What does the airbag control unit 89170-02P60 do?

The airbag control unit 89170-02P60 is the central control unit of the restraint system (SRS) for Toyota. It evaluates the crash sensor signals and decides in an accident, within milliseconds, whether airbags and seatbelt pretensioners are triggered. It monitors the system continuously, and faults appear via the airbag warning light.

Monitoring covers the connected components, their connections and the supply voltage. If a value deviates, the control unit records the finding in the fault memory.

After an accident, the control unit stores crash data and locks itself. This happens regardless of whether airbags actually deployed.

Why does the control unit 89170-02P60 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. In addition, ageing electronic components, cold solder joints, moisture and corrosion at plug connections and voltage spikes from a weak battery or jump starting may be involved.

The crash data sits inside the unit and cannot be seen from outside. A diagnostic tool can reach the data but cannot remove it, which is why it plays a special role in the repair.

The other causes develop over time. Electronic components age, solder joints give way with temperature changes, and moisture or corrosion worsen the contact at plug connections. Voltage spikes when starting also strain the electronics.

Which of these causes is actually present can only be narrowed down after the fault memory has been evaluated.

How can you tell that the 89170-02P60 is defective?

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

The airbag warning light is the most important warning sign. It shows that the restraint system has detected a fault, and it must not be ignored.

The fault message in the instrument cluster names the problem, but not its cause. If the diagnostic tool also cannot connect, the control unit itself may be affected, and the check should take place soon.

Compare the part number on the label of the removed unit with this page. This only establishes that you have the correct unit. Also have the fault memory read out, because only this 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 89170-02N50, 89170-02T10, 89170-02W80, 89170-0F150.

How does the repair of the 89170-02P60 work?

First have the fault memory read out 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 carefully. Processing at Airbag24 usually takes 3–4 working days.

Airbag24 checks the control unit on the test bench, replaces defective components, erases the stored crash data and carries out a function test. Afterwards your own unit is returned to you.

This sequence serves your safety. The 3–4 working days apply only to checking, repairing and testing at Airbag24.

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 89170-02P60 get to Airbag24?

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

Put the printed repair order into the parcel and pack the unit shock-proof.
