Airbag control unit with part number 89170-06490

What does the airbag control unit 89170-06490 do?

The unit 89170-06490 is the SRS control unit of Toyota and therefore the central unit of the restraint system. In a crash it decides within milliseconds which airbags and seatbelt pretensioners are triggered, and the crash sensors supply it with the data for this.

It also monitors the components and wiring of the system continuously. If it detects a fault, it stores it and reports it via the airbag warning light.

As soon as an accident has occurred, crash data is stored in the unit, and it locks itself.

Why does the control unit 89170-06490 fail?

The most common cause with 89170-06490 is stored crash data after an accident, even without a triggered airbag. A standard diagnostic tool cannot erase it. Other causes are aged components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes.

The crash data is held in the memory of the control unit, and standard diagnostic tools cannot reach it.

Electronics age, solder joints can go cold, and moisture attacks plugs. Voltage spikes, for example from a weak battery or jump-starting, can also damage the unit.

How can you tell that the 89170-06490 is defective?

A defect in the 89170-06490 shows itself when the airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears, or the diagnostic tool cannot establish a connection to the control unit. A fault memory that cannot be cleared is also a sign.

The warning light is the most important warning sign, because it shows the state of the restraint system directly.

In an emergency, airbags and seatbelt pretensioners may then be unable to trigger. Therefore have the fault checked promptly, even if the car otherwise runs without problems.
