Airbag control unit with part number 89170-60261

What does the airbag control unit 89170-60261 do?

The airbag control unit 89170-60261 coordinates the restraint system (SRS) of Toyota and Lexus. It processes the data from the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered. It also monitors the system and reports faults via the airbag warning light.

The evaluation must take place within milliseconds in a crash, which is why the unit is designed for exactly that.

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

Why does the control unit 89170-60261 fail?

On the control unit 89170-60261, stored crash data after an accident is the most common cause, even if no airbag has deployed. Other causes are aged components, cold solder joints, moisture and corrosion at plugs, and voltage spikes.

A usual diagnostic tool cannot erase this crash data. Airbag24 erases it as part of the repair.

In addition, aged electronic components, cold solder joints, and moisture and corrosion at plugs can lead to failure.

Voltage spikes arise, for example, from a weak battery or from jump-starting.

How can you tell that the 89170-60261 is defective?

A defect in the 89170-60261 becomes noticeable when the airbag warning light in the instrument cluster stays on permanently or intermittently, a fault message appears, the diagnostic tool cannot establish a connection to the control unit, or the fault memory cannot be erased.

In this state, airbags and seatbelt pretensioners may fail to trigger in an emergency. This makes a prompt check sensible.

How the fault affects the vehicle in an individual case cannot be determined from the light alone. For that, the fault memory must be read out.
