Airbag control unit with part number 89170-06A00

What does the airbag control unit 89170-06A00 do?

The airbag control unit 89170-06A00 controls the restraint system (SRS) for Toyota. It processes the signals from the crash sensors, decides within milliseconds in the event of an accident whether to deploy airbags and seatbelt pretensioners, and monitors the system continuously. Faults are shown via the airbag warning light.

To do this, the unit works with measured values that it records and evaluates itself on an ongoing basis.

After an accident, it creates crash data and locks itself.

Why does the control unit 89170-06A00 fail?

Stored crash data from an accident is the most common cause, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Other possible causes include aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

This data stays in the memory until the repair erases it.

The remaining causes concern the electronics and their connections; a weak battery or a jump start can cause voltage spikes.

How can you tell that the 89170-06A00 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and an error message appears in the instrument cluster. In addition, the diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared.

In detail, the defect shows up through the following signs:

• Airbag warning light on permanently or intermittently
• Error message in the instrument cluster
• No connection between the diagnostic tool and the control unit
• Fault memory that cannot be cleared

While the light is on, the airbags and seatbelt pretensioners may not deploy in an emergency. This warning signal therefore calls for a prompt check.
