Airbag control unit with part number 89170-06520

What does the airbag control unit 89170-06520 do?

The airbag control unit 89170-06520 manages the restraint system (SRS) of Toyota and is its control unit. It reads the crash sensors, determines in a crash which airbags and seatbelt pretensioners fire, and monitors the system at all times.

It indicates a fault via the airbag warning light in the instrument cluster. After an accident it stores crash data and locks itself.

Triggering takes place within fractions of a second, and monitoring runs in the background for as long as the vehicle is in operation.

Why does the control unit 89170-06520 fail?

Stored crash data from an accident is the most common cause, even if no airbag has triggered; a standard diagnostic tool cannot reach it. Other causes are aged components, cold solder joints, moisture and corrosion at connectors, as well as voltage spikes.

Airbag24 erases the crash data during the repair. The other causes can be checked on the unit itself once it has arrived at Airbag24.

Voltage spikes arise, for example, from a weak battery or when starting with jump leads.

How can you tell that the 89170-06520 is defective?

A defect on the 89170-06520 shows itself through the airbag warning light in the instrument cluster, which lights up permanently or intermittently, a fault message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

• Airbag warning light lit in the instrument cluster, permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool cannot reach the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may possibly not trigger while such a finding exists. Please have the system checked promptly.
