Airbag control unit with part number 89170-0R130

What does the airbag control unit 89170-0R130 do?

The airbag control unit 89170-0R130 is the link between the sensors and the triggers in the restraint system (SRS) of the Toyota. In a crash it processes the crash sensors and decides within milliseconds on the airbags and seatbelt pretensioners. After an accident it stores crash data and locks itself.

Apart from a real crash, the unit monitors the system continuously and records faults in the fault memory.

The seatbelt pretensioners tighten the belt in a crash, and the control unit coordinates them with the airbags.

Why does the control unit 89170-0R130 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool does not erase it. Other causes that may come into question relate to the electronics:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery or jump-starting

An airbag that remained undamaged says nothing about whether the control unit has stored crash data.

How can you tell that the 89170-0R130 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. A fault message in the instrument cluster, a diagnostic tool without a connection and a fault memory that cannot be cleared may also appear. In that case the airbags and seatbelt pretensioners may not deploy in a crash.

The warning light is the most direct indication of a fault in the control unit or its surroundings. So please have it checked promptly.

Comparing the part number on the label with this page only shows that the unit matches the page. The cause of the failure is revealed only by reading out the fault memory. So have it read out before removal.

For the same vehicles, we also repair control units with the part numbers 150800-4431, 152100-0262, 152100-4560, 89170-42400, 89170-42870, 89170-42A60.

How does the repair of the 89170-0R130 work?

First have the fault memory read out and enclose the log. Then disconnect the battery and only after that remove the control unit. Finally, create a repair order online and send the unit off well packed. Airbag24 usually needs 3–4 working days to process it.

Airbag24 examines the unit on the test bench, has defective components repaired and erases the stored crash data. A function test follows, and your own unit is then sent back.

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 89170-0R130 get to Airbag24?

You send the control unit yourself, or you book a UPS collection for an extra charge. After the repair, UPS brings it back.

The repair order must be printed out and placed in the package, and the unit needs shock-proof packaging.
