Airbag control unit with part number 89170-02T60

What does the airbag control unit 89170-02T60 do?

The airbag control unit 89170-02T60 is the central control unit of the restraint system (SRS) for Toyota. It evaluates the signals from the crash sensors and determines within milliseconds which airbags and seatbelt pretensioners are triggered.

The unit also monitors the entire system and shows faults via the airbag warning light in the instrument cluster.

After an accident it stores crash data and is locked afterwards.

Why does the control unit 89170-02T60 fail?

The most common cause with the 89170-02T60 is crash data that remained in memory after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase this data. Aged electronic components, cold solder joints and moisture at the plug connectors are also possible causes.

Voltage spikes also count among the possible causes, for example when the battery is weak or a jump start was needed.

Airbag24 erases the crash data during the repair. Which of the other causes applies is established only by the inspection on the test bench.

How can you tell that the 89170-02T60 is defective?

A defect on the 89170-02T60 shows up as the airbag warning light in the instrument cluster, which lights up permanently or only intermittently. A fault message may also appear, or the diagnostic tool may receive no connection to the control unit. In an emergency, airbags and seatbelt pretensioners may then not deploy.

A fault memory that cannot be erased indicates a fault that is still present. Reading it out gives a more precise picture.
