Airbag control unit with part number 89170-33250

What does the airbag control unit 89170-33250 do?

As the airbag control unit, the 89170-33250 controls the restraint system (SRS) of Toyota. It processes the signals from the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners are to trigger, and monitors the system continuously.

The system indicates faults via the airbag warning light in the instrument cluster. After an accident it stores crash data and locks itself. Without this monitoring the vehicle would not know whether the system is ready for operation.

Why does the control unit 89170-33250 fail?

Stored crash data is the most common cause: it arises after an accident, even if no airbag was triggered, and it cannot be erased with a normal diagnostic tool. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Erasing the crash data is part of the repair at Airbag24, because an ordinary diagnostic tool cannot do this.

Electronic components age, and solder joints can go cold over time. Moisture and corrosion at plug connections affect the contact.

Voltage spikes arise, for example, from a weak battery or a jump start and can damage the unit.

How can you tell that the 89170-33250 is defective?

A defect shows up first as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition there are fault messages in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may fail to trigger as long as the defect persists.

Such a warning requires attention.

By comparing the part number with the label of the removed unit you check whether it is the right unit; this comparison tells you no more than that. Whether the control unit is defective or a plug or a cable is the cause is shown by the fault memory. So have it read out beforehand.

For the same vehicles, we also repair control units with the part numbers 89170-33430, 89170-33470, 89170-33530.
