Airbag control unit with part number 89170-02B60

What does the airbag control unit 89170-02B60 do?

The airbag control unit 89170-02B60 is the control unit of the restraint system (SRS) in Toyota. It decides within fractions of a second in a crash which airbags and seatbelt pretensioners are triggered.

To do so, it reads the signals of the impact sensors. During normal operation, it monitors the entire system and reports faults via the airbag warning light in the instrument cluster.

After an accident, the unit stores crash data and locks itself. Anyone diagnosing it later needs to know this state.

Why does the control unit 89170-02B60 fail?

The most common cause is stored crash data after an accident, even if no airbag was triggered. A standard diagnostic tool cannot erase this data, which is why the fault message remains.

Airbag24 erases the crash data during the repair. The send-in procedure is designed precisely for this case.

Other causes can be of a more general nature:

• Ageing electronic components
• Cold solder joints on the circuit board
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or jump start

How can you tell that the 89170-02B60 is defective?

A defect shows up as an airbag warning light in the instrument cluster that stays on permanently or intermittently. A fault message and a fault memory that cannot be cleared may be added as well.

Even if a diagnostic tool cannot establish a connection to the control unit, this points to a problem. A fault memory that remains unchanged is also a finding.

As long as a fault exists, airbags and seatbelt pretensioners may not be able to deploy in an emergency.
