Airbag control unit with part number 89170-06300

What does the airbag control unit 89170-06300 do?

The airbag control unit 89170-06300 is the central control unit of the restraint system (SRS) for Toyota. It evaluates the signals from the crash sensors and decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered. After an accident it stores crash data and locks itself.

In everyday use the control unit monitors the entire system continuously, including the sensors and the wiring of the triggers. If it detects a fault, it shows it via the airbag warning light in the instrument cluster, so that you can react.

The stored crash data records what the unit registered during the accident. It sits in the control unit itself and is kept separate from the other vehicle data.

Why does the control unit 89170-06300 fail?

With the control unit 89170-06300, the most common cause is that crash data was stored after an accident, even if no airbag was triggered. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

A normal diagnostic tool cannot erase this crash data. Airbag24 erases it during the repair, so that no old entry remains in the unit afterwards.

The other causes include in particular:

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

How can you tell that the 89170-06300 is defective?

On the control unit 89170-06300 you recognise a defect by the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition there is an error message in the instrument cluster, no connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

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

As long as the warning light shows the fault, airbags and seatbelt pretensioners may possibly not trigger in an emergency. A displayed fault should therefore be checked promptly, even if the vehicle seems to run normally in daily use.
