Airbag control unit with part number 89170-0P010

What does the airbag control unit 89170-0P010 do?

In Toyota models, the airbag control unit 89170-0P010 is the central evaluation unit of the restraint system (SRS). It records the crash sensors, decides in an accident within milliseconds on the activation of airbags and seatbelt pretensioners, and monitors the system continuously. Faults appear via the airbag warning light.

During operation, the unit logs its test results in the fault memory, which a diagnostic tool can read out.

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

Why does the control unit 89170-0P010 fail?

In the control unit 89170-0P010, the most common cause is crash data that remains stored after an accident, even without a triggered airbag. A normal diagnostic tool does not remove it. Aged electronics, cold solder joints, moisture or corrosion at plugs, and voltage spikes are also possible causes.

The data itself cannot be erased with simple means. Airbag24 removes it during the repair, which is part of the work.

Components age over the years, and solder joints can become brittle.

In addition, moisture and rust affect the plug connections, and voltage spikes, for example from a weak battery or jump-starting, stress the electronics.

How can you tell that the 89170-0P010 is defective?

A defect in the 89170-0P010 is indicated by the airbag system warning light, which stays on permanently or keeps flashing. In addition, error messages appear in the instrument cluster, a diagnosis fails because of the lack of contact, or the fault memory remains. Airbags and seatbelt pretensioners may then not trigger in an emergency.

These are the signs to watch for:

• Airbag warning light stays on permanently or keeps flashing
• Error message in the instrument cluster
• Diagnostic tool remains without connection to the control unit
• Fault memory cannot be reset

The warning light is the signal from the control unit itself. A light that does not go out calls for a prompt check.

Which vehicles is the 89170-0P010 fitted in?

The control unit 89170-0P010 is fitted in these vehicles: Toyota RAV4 XA30 (2006-2009) and XA30 Facelift (2009-2013). Comparing the part number on the label of the removed unit with this page only confirms the assignment, and nothing more.

These models are recorded for this part number:

• Toyota RAV4 XA30 (2006-2009)
• Toyota RAV4 XA30 Facelift (2009-2013)

Reading the fault memory decides whether the control unit is defective or whether a plug or cable causes the problem. This step therefore comes before removal.

For the same vehicles, we also repair control units with the part numbers 150300-8850, 89170-0R022, 89170-0R140, 89170-42201, 89170-42210, 89170-42420.

How does the repair of the 89170-0P010 work?

You begin by reading out the fault memory and enclose the log. Then you disconnect the battery and only after that remove the control unit 89170-0P010. Next, create a repair order online and send the unit off well packed. Airbag24 usually needs 3–4 working days for processing.

The sequence serves safety.

After arrival, Airbag24 examines the unit, replaces defective components where necessary, erases crash data and finally tests it before it reaches you again.

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.
