Airbag control unit with part number 89170-02600

What does the airbag control unit 89170-02600 do?

The airbag control unit 89170-02600 is the central control of the restraint system (SRS) for Toyota. It receives the messages from the crash sensors, selects the suitable airbags and seatbelt pretensioners in an accident within milliseconds, and monitors itself as well as the system continuously. Faults are reported via the airbag warning light.

This monitoring runs in the background and only becomes noticeable to you when a deviation occurs.

After an accident the unit stores crash data and locks itself.

Why does the control unit 89170-02600 fail?

The most common cause is crash data after an accident, even if no airbag was triggered. A normal diagnostic tool cannot erase it. Other causes are aged components, cold solder joints, corrosion on plug connectors and voltage spikes.

The other causes in detail include:

• aged electronic components
• cold solder joints
• moisture and corrosion on plug connectors
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 89170-02600 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and an error message appears in the instrument cluster. Add to this a diagnostic tool that cannot reach the control unit, or a fault memory that cannot be cleared. In that case airbags and seatbelt pretensioners may possibly not trigger in an emergency.

The light is the most visible sign for you that something is wrong with the system. That is precisely why it must not be ignored, even if the car otherwise drives normally.

Have the restraint system checked promptly, before you drive further.
