Airbag control unit with part number 89170-33200

What does the airbag control unit 89170-33200 do?

The airbag control unit 89170-33200 controls the restraint system (SRS) of Toyota. It reads the signals from the crash sensors, triggers airbags and seatbelt pretensioners in the event of an accident, and decides this within milliseconds. At the same time, it monitors the entire system and displays faults via the airbag warning light.

All sensors report their values to the control unit, and from it the commands go out to the airbags and seatbelt pretensioners. Without a working control unit, the system cannot perform its task.

After an accident, the control unit stores crash data and locks itself.

Why does the control unit 89170-33200 fail?

The most common cause: crash data stored after an accident, even without a deployed airbag. It cannot be removed with a normal diagnostic tool. Other causes include aged components, cold solder joints, moisture and corrosion on connectors, and voltage spikes, for example with a weak battery or a jump start.

Stored crash data belongs to the unit and stays there until it is removed during a repair.

Aged electronic components lose performance over time. Cold solder joints can already arise during manufacturing and only show up under temperature changes. Moisture and corrosion attack the contacts, and voltage spikes can put a strain on the electronics.

How can you tell that the 89170-33200 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message appears there. In addition, a diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared.

When the light is on, airbags and seatbelt pretensioners may not trigger in an emergency. Such warnings should therefore be checked promptly.

If the light comes back after a drive, it is worth noting the date and time. This helps the workshop when reading out the fault memory.

Which vehicles is the 89170-33200 fitted in?

The control unit 89170-33200 is fitted in these vehicles: Toyota Camry XV20 Facelift (2000-2001) and XV20 (1996-2000). A look at the vehicle documents will show whether your car is one of the models.

The vehicles at a glance:

• Toyota Camry XV20 Facelift (2000-2001)
• Toyota Camry XV20 (1996-2000)

First compare the part number on the label of the removed unit with this page. That only shows that it is the correct unit. Then have the fault memory read out, because the result shows whether the control unit itself is defective or whether a plug or a cable is the cause.

How does the repair of the 89170-33200 work?

First have the fault memory read out and attach the log, then disconnect the battery and only then remove the control unit. Afterwards, create a repair order online and send in the unit well packed. At Airbag24, inspection, repair and function test usually take 3–4 working days.

At Airbag24, defective components are repaired, stored crash data is erased, and a function test follows. Then the unit is sent back 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 89170-33200 get to Airbag24?

You send the unit as a parcel, or you book a UPS collection for an extra charge. The return after the repair is also made by UPS.

Put the printed repair order in the parcel. Pack the control unit shockproof so it survives the journey undamaged.
