Airbag control unit with part number 89170-26250

What does the airbag control unit 89170-26250 do?

The airbag control unit 89170-26250 is the control unit of the restraint system (SRS) of Toyota in the vehicle. It evaluates the signals from the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

The fault is displayed via the airbag warning light in the instrument cluster.

Why does the control unit 89170-26250 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 are ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery.

Crash data alone says nothing about the condition of individual components. The other causes develop over a longer period.

Voltage spikes occur, for example, with a weak battery or when jump-starting. Only the inspection shows which cause actually applies.

How can you tell that the 89170-26250 is defective?

The airbag warning light stays on permanently or intermittently. In addition there are error messages in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared.

The light is a direct sign that the system has detected a fault. An intermittent light also counts, because the control unit has then already detected the fault.

In an accident, it can happen that airbags and seatbelt pretensioners do not trigger.
