Airbag control unit with part number 89170-60471

What does the airbag control unit 89170-60471 do?

The airbag control unit 89170-60471 processes the signals of the crash sensors within the restraint system (SRS) of Toyota. In an accident it triggers the matching airbags and seatbelt pretensioners within milliseconds.

The unit monitors the entire system continuously. If a fault occurs, the airbag warning light in the instrument cluster draws attention to it.

If an accident occurs, the control unit creates crash data and locks itself.

Why does the control unit 89170-60471 fail?

The most common cause on the 89170-60471 is crash data that remains in the unit after an accident, even if no airbag has fired. A normal diagnostic tool is not able to erase it. Other causes are ageing, cold solder joints, moisture and voltage spikes.

Ageing electronic components and cold solder joints can cause faults that become noticeable over time.

Moisture and corrosion at plug connections, as well as voltage spikes, for example from a weak battery or jump-start, also belong to the causes. Airbag24 erases the crash data during the repair.

How can you tell that the 89170-60471 is defective?

If the airbag warning light in the instrument cluster lights up permanently or intermittently, the 89170-60471 is signalling a fault. In addition there are error messages in the instrument cluster, a lack of connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may not trigger.

The display in the instrument cluster is therefore the visible sign that a check is due.
