Airbag control unit with part number 89170-06620

What does the airbag control unit 89170-06620 do?

The airbag control unit 89170-06620 coordinates the restraint system (SRS) for Toyota. It processes the signals from the crash sensors, selects within milliseconds in a crash which airbags and seatbelt pretensioners are triggered, and monitors all components continuously. If it detects a malfunction, it reports it via the airbag warning light.

During normal driving the monitoring continues unobtrusively, so you notice nothing of it.

After a crash, the unit stores crash data and locks itself.

Why does the control unit 89170-06620 fail?

Stored crash data is the most important cause of a failure, even when no airbag has deployed. A standard diagnostic tool cannot remove it. Besides that, aged electronics, cold solder joints, moisture and corrosion on plugs, and voltage spikes come into question.

Airbag24 removes the crash data as part of the repair, so you do not need to do anything for it.

The other causes mainly concern the connections and the components themselves. Solder joints and plug connections can be exposed to moisture or corrosion without it being visible from outside.

Voltage spikes arise, for example, from a weak battery or from a jump start.

How can you tell that the 89170-06620 is defective?

A defect shows mainly on the airbag warning light, which lights up permanently or intermittently. A fault message in the instrument cluster, a diagnostic tool without contact to the control unit or a fault memory that cannot be cleared are also signs; in an emergency, airbags and seatbelt pretensioners may then not deploy.

The warning light is one of the most important signals in the vehicle, because it shows the state of the system directly.

As soon as any of these indications appears, have the system checked promptly and do not wait for a later time.
