Airbag control unit with part number 89170-06131

What does the airbag control unit 89170-06131 do?

The control unit 89170-06131 is the central unit of the SRS restraint system of Toyota. It processes the signals from the crash sensors and decides in an accident which airbags and seatbelt pretensioners trigger, within a few milliseconds. At the same time it monitors the entire system and indicates faults via the airbag warning light.

To do so, the unit checks sensors, wiring and triggers during operation. Faults that occur are stored in the fault memory, which a workshop can read out later.

After an accident it stores crash data and locks itself.

Why does the control unit 89170-06131 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase this data, but Airbag24 erases it during the repair. In addition, aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes play a role.

Crash data is stored even when no airbag has deployed. The unit registers an event and keeps a record of it, regardless of whether restraint devices have reacted.

The other causes act over a longer period. Older components weaken, solder joints can go cold, and moisture attacks contacts. Voltage spikes, for example from a weak battery or when a jump start is connected, place an additional load on the electronics.

How can you tell that the 89170-06131 is defective?

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

The warning light is the most important indication of a fault. It reports a fault as soon as the unit detects it.

Faults that occur only occasionally can also appear in the fault memory.

Matching the part number on the label with this page ensures only that you have the correct unit. The fault memory is read out before you remove the unit, as only the result shows whether the control unit is defective or a plug or cable is the cause.

How does the repair of the 89170-06131 work?

First have the fault memory read out and enclose the log, then disconnect the battery and only then remove the control unit. Afterwards, create a repair order online and pack the unit well before sending it. Airbag24 checks it on the test bench, replaces defective components, erases the stored crash data and carries out a function test.

Processing at Airbag24 takes 3–4 working days as a rule and covers exclusively checking, repairing and testing.

Afterwards your own unit is returned to you.

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.

How does the control unit 89170-06131 get to Airbag24?

You send the unit as a parcel, or you have it collected by UPS at home for an extra charge. Airbag24 sends it back by UPS after the repair. The printed repair order goes in the parcel, and the unit is packed shock-proof.

Cushioned in a box, the unit arrives safely.
