Airbag control unit with part number 89170-52760

What does the airbag control unit 89170-52760 do?

The airbag control unit 89170-52760 coordinates the restraint system (SRS) in Toyota. In an accident it processes the signals from the crash sensors and decides within milliseconds which airbags and seatbelt pretensioners are triggered.

During normal operation it monitors the system continuously; faults appear on the airbag warning light in the instrument cluster.

After an accident the control unit stores crash data and locks itself. The lock is only lifted by the repair.

Why does the control unit 89170-52760 fail?

The most frequent cause is crash data from an accident that is stored even when no airbag has deployed. Further causes are aged components, cold solder joints, moisture and corrosion on plugs, and voltage spikes.

A normal diagnostic tool cannot delete this crash data. Airbag24 deletes it during the repair. The other causes concern components, solder joints and contacts.

• Aged components
• Cold solder joints
• Moisture and corrosion on plugs
• Voltage spikes, for example from a jump start

How can you tell that the 89170-52760 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. Fault messages may accompany it, the diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared. Then airbags and seatbelt pretensioners may not deploy in an emergency.

The warning light coming on is one of the first hints the system gives. The warning must be investigated promptly, before the vehicle is used in everyday traffic.
