Airbag control unit with part number 89170-02W60

What does the airbag control unit 89170-02W60 do?

The airbag control unit 89170-02W60 brings together the SRS restraint system of Toyota. It measures through the crash sensors whether an impact requires deployment, and then triggers the airbags and seatbelt pretensioners; the decision is made within milliseconds.

While driving, it monitors the system and shows faults on the airbag warning light. After an accident it stores crash data and locks itself. Only the repair lifts the lock.

Why does the control unit 89170-02W60 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Other causes are ageing electronic components, cold solder joints, moisture and corrosion at connectors, and voltage spikes.

Crash data stays in the unit, because a standard diagnostic tool cannot remove it. Airbag24 deletes it during the repair.

The other causes act over a longer period. Electronic components age, solder joints can lose contact, and moisture attacks the connectors.

Voltage spikes arise, for example, with a weak battery or when a jump start is connected, and add further strain on the unit.

How can you tell that the 89170-02W60 is defective?

A defect shows itself through signs such as an airbag warning light in the instrument cluster that stays on permanently or intermittently, a fault message, no connection to the diagnostic tool, or a fault memory that cannot be cleared. In that case, airbags and seatbelt pretensioners may not deploy.

In everyday use, you will notice these points:

• Airbag warning light in the instrument cluster stays on permanently or intermittently
• Fault message in the instrument cluster
• The diagnostic tool receives no connection to the control unit
• The fault memory cannot be cleared

The warning light remains the key signal, because it shows the state of the system at all times.

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 89170-02W60 work?

At Airbag24, processing usually takes 3–4 working days. Before that, you have the fault memory read out, enclose the readout log and disconnect the battery before you remove the control unit. Afterwards you create a repair order online and send the unit in, well packed.

This sequence serves safety during removal.

At Airbag24, the unit is first checked on the test bench. Defective components are replaced, the crash data is removed, and finally a function test is carried out before your own unit is sent back.

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.
