Airbag control unit with part number 89170-06240

What does the airbag control unit 89170-06240 do?

The airbag control unit 89170-06240 controls the restraint system (SRS) of Toyota. 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.

If the control unit detects a fault, it reports it via the airbag warning light in the instrument cluster and stores the error in the fault memory. This makes it possible to trace later which area was affected.

After an accident the unit stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit 89170-06240 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Other causes are ageing components, cold solder joints, moisture and voltage spikes.

• ageing electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

Airbag24 erases the crash data during the repair. Which of the other causes is actually present is shown only by the inspection of the unit.

How can you tell that the 89170-06240 is defective?

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

• Airbag warning light lit permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool finds no connection to the control unit
• Fault memory cannot be cleared

As long as such a fault exists, airbags and seatbelt pretensioners may not deploy in an emergency. So have the display checked promptly instead of carrying on driving.
