Airbag control unit with part number 89170-04060

What does the airbag control unit 89170-04060 do?

The airbag control unit 89170-04060 controls the restraint system (SRS) in vehicles from Toyota. It evaluates crash sensors, determines which airbags and seatbelt pretensioners are triggered in an accident, and monitors the system permanently. Faults appear on the airbag warning light.

The monitoring runs in the background while the vehicle is driving. The unit records irregularities and stores them in the fault memory.

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

Why does the control unit 89170-04060 fail?

The most common cause is that crash data was stored in the unit after an accident, even if no airbag has deployed. Other causes include ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A standard diagnostic tool cannot delete this crash data. The other causes arise over time or through external influences such as wetness, for example during jump-starting or with a weak battery producing voltage spikes.

These causes act differently. Whether one of them is present is only shown by the fault memory that has been read out.

How can you tell that the 89170-04060 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition the instrument cluster shows an error message, the diagnostic tool finds no contact with the control unit, or the fault memory cannot be cleared.

The light alone does not show where exactly the fault lies. It does show, however, that something in the system is wrong, and this warning should be checked.

In an emergency, airbags and seatbelt pretensioners may not trigger. This applies to every detected defect on the control unit.
