Airbag control unit with part number 89170-06570

What does the airbag control unit 89170-06570 do?

The airbag control unit 89170-06570 is responsible for the restraint system (SRS) of Toyota. It checks signals from the crash sensors and triggers the appropriate airbags and seatbelt pretensioners within milliseconds in an accident. After an accident it stores crash data and locks itself.

The unit runs in the background during operation and monitors sensors, actuators and wiring. It indicates a fault via the airbag warning light in the instrument cluster.

Why does the control unit 89170-06570 fail?

Stored crash data from an accident is the most common cause in the control unit 89170-06570, even if no airbag has triggered. This data cannot be erased with an ordinary diagnostic tool. In addition, there are aged electronics, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Crash data therefore belongs on the checklist as soon as the unit comes from an accident vehicle. An airbag does not need to have triggered for this.

How can you tell that the 89170-06570 is defective?

A defect in the control unit 89170-06570 shows up as the airbag warning light lighting up permanently or intermittently, and as an error message in the instrument cluster. The diagnostic tool does not reach the control unit, or the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then possibly not trigger in an emergency.

Pay attention to these signs in particular:

• Airbag warning light on, permanently or intermittently
• Error message in the instrument cluster
• No connection to the control unit with the diagnostic tool
• Fault memory cannot be cleared
