Airbag control unit with part number 89170-02N60

What does the airbag control unit 89170-02N60 do?

The airbag control unit 89170-02N60 coordinates the restraint system (SRS) of Toyota. It recognises an impact via the crash sensors and decides within milliseconds whether airbags and seatbelt pretensioners are fired. At the same time it monitors the entire system and shows faults via the airbag warning light.

In operation the check runs without any intervention by the driver. The unit compares measured values and connections with the expected states.

After an accident it stores crash data and locks itself. The lock is part of the design of the system.

Why does the control unit 89170-02N60 fail?

Stored crash data after an accident is the most common cause, even if no airbag has fired. Other causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes from a weak battery or jump-starting.

A normal diagnostic tool cannot erase crash data. Airbag24 removes it deliberately during the repair.

The remaining causes develop over time. Components age, solder joints can go cold, and moisture and corrosion attack plug connections. Voltage spikes also put short-term strain on the electronics.

How can you tell that the 89170-02N60 is defective?

Stored crash data does not always produce visible signs, but the airbag warning light in the instrument cluster lights up permanently or intermittently.

In addition there are a fault message in the instrument cluster, a diagnostic tool without connection to the control unit, and a fault memory that cannot be cleared. These signs indicate a fault.

• Airbag warning light on permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool finds no connection to the control unit
• Fault memory cannot be cleared

With these signs, airbags and seatbelt pretensioners may fail to trigger in an emergency. Therefore have the condition checked promptly.
