Airbag control unit with part number 89170-0E680

What does the airbag control unit 89170-0E680 do?

The airbag control unit 89170-0E680 coordinates the restraint system (SRS) of Toyota. It continuously checks the signals from the crash sensors and decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered. Faults are reported via the airbag warning light in the instrument cluster.

The evaluation runs in the background while driving, without the driver having to intervene.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 89170-0E680 fail?

Crash data stored after an accident is the most common cause, even if no airbag was triggered. A normal diagnostic tool cannot erase this data. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes, can also be involved.

Crash data is listed first because it remains in the memory after the accident. The other causes act on the electronics themselves and on the contacts.

Voltage spikes occur, for example, with a weak battery or when jump-starting. Which cause applies in an individual case is shown by the test.

How can you tell that the 89170-0E680 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. A fault message in the instrument cluster may appear as well. If no connection to the diagnostic tool can be made, or the fault memory cannot be cleared, there is a finding.

With such a finding, airbags and seatbelt pretensioners may not trigger in an emergency. The warning light makes the finding visible, and you should act on it.

A missing connection to the diagnostic tool does not have to be caused by the control unit. Cables and plugs can also be responsible.
