Airbag control unit with part number 89170-02R60

What does the airbag control unit 89170-02R60 do?

The 89170-02R60 is the central control unit of the restraint system (SRS) for Toyota. It evaluates the crash sensors, decides within milliseconds in an emergency on airbags and seatbelt pretensioners, and monitors the system continuously.

It reports faults via the airbag warning light in the instrument cluster and stores them in the fault memory. This allows the status of the system to be traced at any time.

After an accident the unit stores crash data and locks itself. This state is decisive for diagnosis.

Why does the control unit 89170-02R60 fail?

The most common cause is stored crash data after an accident, even if no airbag has fired; a normal diagnostic tool cannot erase it. Further causes are aged components, cold solder joints, moisture and corrosion, and voltage spikes.

The crash data remains stored even though no airbag had to fire. Airbag24 erases it during the repair, before the unit runs through the functional test.

Further causes include:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes from a weak battery or jump-starting

How can you tell that the 89170-02R60 is defective?

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

The light shows the fault, and that is its job. With this light, a prompt read-out of the fault memory is worthwhile, because only then is the cause visible.

A missing connection to the diagnostic tool or a fault memory that cannot be emptied are also typical signals. A reliable statement only comes from the evaluation.

The following notes will help you. Compare the part number on the label of the removed unit with this page, so that you can be sure you have the correct unit. Also have the fault memory read out beforehand, because only that shows whether the control unit itself is defective or whether a plug or a 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 89170-02R60 work?

First have the fault memory read out and enclose the log, then disconnect the battery and only then remove the 89170-02R60. Then create a repair order online and send in the well-packed unit; Airbag24 checks it on the test bench, replaces defective components, erases the crash data and carries out a functional test. Processing at Airbag24 usually takes 3–4 working days.

The order keeps you safe during removal and ensures that the finding is complete. The log must therefore go into the parcel.

After the functional test your own unit is returned. 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 89170-02R60 get to Airbag24?

You send the 89170-02R60 in as a parcel or book a UPS collection for an extra charge; after the repair Airbag24 sends it back to you by UPS.
