Airbag control unit with part number 89170-42260

What does the airbag control unit 89170-42260 do?

The airbag control unit 89170-42260 is the central control unit of the restraint system (SRS) for Toyota. It evaluates signals from the crash sensors, decides in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system permanently.

The unit shows faults via the airbag warning light in the instrument cluster. The decision in a crash is made within fractions of a second, which is why monitoring runs without a pause.

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

Why does the control unit 89170-42260 fail?

The most common cause is crash data that remains in the memory after an accident, even if no airbag has deployed. An ordinary diagnostic tool cannot erase it. In addition, aged electronics, cold solder joints, moisture at plug connections and voltage spikes play a role.

Crash data does not disappear on its own. To narrow down the cause reliably, you need an inspection on the test bench, because the component affected cannot be identified from the outside.

Airbag24 erases the stored crash data during the repair.

How can you tell that the 89170-42260 is defective?

A defect becomes apparent through the airbag warning light in the instrument cluster, which lights up permanently or intermittently, through error messages in the instrument cluster, through a diagnostic tool without a connection to the control unit, or through a fault memory that cannot be cleared.

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

In an emergency, the airbags and seatbelt pretensioners may possibly not deploy in the case of such a defect.
