Airbag control unit with part number 89170-06A10

What does the airbag control unit 89170-06A10 do?

The airbag control unit 89170-06A10 coordinates the triggering of the airbags and seatbelt pretensioners in the Toyota. It reads the crash sensors, makes its decision within milliseconds in a crash and checks the system for faults permanently. The airbag warning light displays every fault detected.

This check also runs while the vehicle is stationary, so that the system stays ready for an emergency.

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

Why does the control unit 89170-06A10 fail?

The most common cause is crash data that remains in the memory after an accident, even when no airbag has deployed. A conventional diagnostic tool cannot remove this data; Airbag24 erases it as part of the repair. Other causes include ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

Crash data records an event, that is, the moment when something happened. It does not yet say whether a component has been damaged.

The other causes arise from age and moisture. Contacts and solder joints change over time, and voltage fluctuations put strain on the circuitry.

How can you tell that the 89170-06A10 is defective?

A defect becomes visible through the airbag warning light in the instrument cluster, which stays on permanently or intermittently. An error message in the instrument cluster, or a diagnostic tool that cannot establish a connection to the control unit, also points to the defect.

Added to this is a fault memory that cannot be cleared. In that case, airbags and seatbelt pretensioners may not deploy in an emergency; have the system checked promptly.

Comparing the part number on the removed unit with this page only clarifies whether it is the right unit. Whether the control unit is really defective, or whether a connector or cable is interfering, is shown only by a read-out fault memory. Have it read out before removal, therefore.

For the same vehicles, we also repair control units with the part numbers 150800-2310, 89170-06770, 89170-06B21.

How does the repair of the 89170-06A10 work?

You begin by reading out the fault memory and enclose the log. Then you disconnect the battery, remove the control unit only after that, and create the repair order online afterwards.

Send in the well-packed unit. Airbag24 checks it on the test bench, repairs defective components, erases stored crash data and carries out a function test.

At Airbag24, these tasks usually take 3–4 working days before the unit is returned.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
