Airbag control unit with part number 89170-0F190

What does the airbag control unit 89170-0F190 do?

For Toyota, the airbag control unit 89170-0F190 controls the restraint system (SRS). It reads the crash sensors, determines in an accident whether airbags and seatbelt pretensioners fire, and checks the system constantly. Faults appear on the airbag warning light.

Without reliable evaluation, the restraint system cannot fulfil its task.

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

Why does the control unit 89170-0F190 fail?

Crash data stored after an accident is the most common cause, even if no airbag has deployed. With this control unit, erasing is often not possible; if you want the crash data erased, contact Airbag24 briefly before sending the unit in, and Airbag24 will then check the part number. Other causes are aged components, cold solder joints, moisture and corrosion, and voltage spikes.

A normal diagnostic tool cannot erase the crash data. Aged components, cold solder joints and moisture at plug connections can affect the unit as well, regardless of an earlier accident.

Voltage spikes arise, for example, from a weak battery or jump-starting. Which cause applies is only narrowed down by the test.

How can you tell that the 89170-0F190 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently if there is a defect in the 89170-0F190. 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.

In an emergency, airbags and seatbelt pretensioners may not deploy as a result. The warning should therefore be checked promptly.

Take the warning seriously, even if it only appears intermittently, because the warning light shows the condition of the system.
