Airbag control unit with part number 89170-06200

What does the airbag control unit 89170-06200 do?

The airbag control unit 89170-06200 is the control unit of the SRS restraint system for Toyota. It reads the signals from the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners to trigger, and monitors the system continuously. After an accident it stores crash data and locks itself.

The unit reports faults via the airbag warning light in the instrument cluster. The crash data remains stored in the unit after the accident.

The control unit is connected to the sensors and triggers by cable, and these lines must be undamaged for an emergency.

Why does the control unit 89170-06200 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; it cannot be erased with a standard diagnostic tool. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes, such as from a weak battery or a jump start.

The crash data is created by the impact itself and remains in the unit afterwards. The fault memory can still be read out, but the crash data itself stays in place.

Regardless of an accident, components can age, solder joints can go cold, and moisture or salt attack the contacts.

How can you tell that the 89170-06200 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, a fault message appears in the instrument cluster, and the diagnostic tool has no connection to the control unit. The fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The list of signs helps you compare with your own vehicle:

• Airbag warning light that lights up permanently or intermittently
• Fault message in the instrument cluster
• No connection to the diagnostic tool
• Fault memory that cannot be cleared

If you notice any of these signs, have the system checked promptly.
