Airbag control unit with part number 89170-0R480

What does the airbag control unit 89170-0R480 do?

The airbag control unit 89170-0R480 controls the restraint system (SRS) for Toyota. It evaluates the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

The unit reports faults via the airbag warning light in the instrument cluster. After an accident the unit stores crash data and locks itself. Only the repair lifts the lock.

Why does the control unit 89170-0R480 fail?

The most common cause of a failure of the 89170-0R480 is crash data stored after an accident, even if no airbag has deployed. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

A standard diagnostic tool cannot erase the crash data. Airbag24 erases it during the repair.

The further causes at a glance:

• aged electronic components
• cold solder joints

How can you tell that the 89170-0R480 is defective?

A defect in the 89170-0R480 shows up as the airbag warning light that stays on permanently or intermittently, as a fault message in the instrument cluster, as a missing connection of the diagnostic tool, and as a fault memory that cannot be cleared.

• The airbag warning light is on permanently or intermittently.
