Airbag control unit with part number 89170-02U60

What does the airbag control unit 89170-02U60 do?

The airbag control unit 89170-02U60 is the central control unit of the restraint system of Toyota. It processes the crash sensor signals, decides in an accident within milliseconds on airbags and seatbelt pretensioners, and monitors the system continuously.

The unit reports faults via the airbag warning light in the instrument cluster. After an accident it secures crash data and then remains locked.

Why does the control unit 89170-02U60 fail?

The most common cause is stored crash data from an accident, even without a triggered airbag, and a normal diagnostic tool cannot erase it. Further causes on the 89170-02U60 are listed below:

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

During the repair Airbag24 removes the crash data. Which of the remaining causes applies is determined by the test on the test bench.

How can you tell that the 89170-02U60 is defective?

A defective 89170-02U60 is revealed by the airbag warning light in the instrument cluster, which stays on permanently or intermittently, by fault messages in the instrument cluster, by a missing connection to the diagnostic tool, and by a fault memory that cannot be cleared.

Airbags and seatbelt pretensioners may then not trigger in an emergency. The indication should therefore be taken seriously and checked promptly.
