Airbag control unit with part number 89170-60190

What does the airbag control unit 89170-60190 do?

The airbag control unit 89170-60190 forms the central control unit of the SRS restraint system for Toyota. It processes the messages from the crash sensors, decides in an accident within fractions of a second on the deployment of airbags and seatbelt pretensioners, and monitors all components continuously. If it detects a fault, it shows this via the airbag warning light.

After an accident it stores crash data and locks itself.

Why does the control unit 89170-60190 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a standard diagnostic tool cannot erase it. Aged electronic components, cold solder joints, moisture and corrosion at plug connectors and voltage spikes are also possible causes.

Troubleshooting is not made easier by this: which of the causes named is present is established only by reading out the fault memory. Voltage spikes arise, for example, from a weak battery or from a jump start.

How can you tell that the 89170-60190 is defective?

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

A permanently lit warning light is a clear signal and should be checked promptly.
