Airbag control unit with part number 89170-0DG10

What does the airbag control unit 89170-0DG10 do?

The airbag control unit 89170-0DG10 is the central control unit of the SRS system for Toyota. It evaluates the signals from the crash sensors and decides in an accident, within milliseconds, which airbags and seatbelt pretensioners are triggered.

It monitors the system permanently and shows faults via the airbag warning light.

After an accident it stores crash data and then locks itself.

Why does the control unit 89170-0DG10 fail?

The most common cause for the 89170-0DG10 is crash data from an accident, even if no airbag has deployed. Further causes act over a longer period of time.

Crash data remains stored until it is specifically erased. A normal diagnostic tool is not sufficient for this.

Further causes include:

• aged electronic components
• cold solder joints on the circuit boards
• moisture and corrosion on plug connectors
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 89170-0DG10 is defective?

A defect in the 89170-0DG10 shows itself through the airbag warning light, through a fault message or through the diagnostic tool being unable to reach the control unit. A fault memory that cannot be cleared is also an indication.

The airbag warning light in the instrument cluster lights up permanently or intermittently. A fault message in the instrument cluster is added to this.

In an emergency, airbags and seatbelt pretensioners may not deploy with such a finding. Have the system checked promptly.
