Airbag control unit with part number 89170-06470

What does the airbag control unit 89170-06470 do?

The airbag control unit 89170-06470 controls the restraint system of Toyota. It reads the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners are triggered. After an accident it stores crash data and locks itself.

During operation the unit continuously checks all connections of the system. If it finds a fault, it switches on the airbag warning light in the instrument cluster.

This keeps the function of the restraint system monitored in daily use, even if you notice nothing of it.

Why does the control unit 89170-06470 fail?

Crash data stored after an accident are the most common cause in the control unit 89170-06470, even if no airbag has deployed. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

A normal diagnostic tool cannot erase crash data. Airbag24 therefore erases them during the repair.

The other causes relate mainly to the age and the environment of the electronics. Solder joints lose their firmness over time, moisture attacks plug contacts, and voltage spikes arise, for example, from a weak battery or from jump-starting.

How can you tell that the 89170-06470 is defective?

A defect in the control unit 89170-06470 shows first on the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Also present are an error message in the instrument cluster, no connection to the diagnostic tool and a fault memory that cannot be cleared. Then airbags and seatbelt pretensioners may not deploy in an emergency.

The airbag warning light in the instrument cluster shows the fault as soon as the control unit detects it. A permanent or intermittent light is therefore a reason to have the system checked.

The fault memory also remains if the unit cannot be read out or cleared. This too is a sign of a fault in the control unit itself.
