Airbag control unit with part number 89170-60F90

What does the airbag control unit 89170-60F90 do?

For Toyota, the airbag control unit 89170-60F90 is the control unit of the restraint system (SRS). It processes the signals from the crash sensors and determines in a crash which airbags and seatbelt pretensioners are triggered.

In addition, it monitors all components continuously. If a fault occurs, the unit reports it via the airbag warning light in the instrument cluster.

After a crash, it stores crash data and locks itself.

Why does the control unit 89170-60F90 fail?

The most common cause with the 89170-60F90 is crash data from an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase this data; at Airbag24, it is erased during the repair. Other causes are ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage peaks.

Stored crash data is not proof of damage to the unit itself, but it indicates an incident. That is why, after an accident, it is worth thinking of this first.

The other causes affect the electronics and their connections. Components age, solder joints can go cold, and moisture attacks the contacts. Voltage peaks occur, for example, with a weak battery or when jump-starting.

How can you tell that the 89170-60F90 is defective?

A defect in the 89170-60F90 first shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. An error message accompanies it. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

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

Any one of these signs justifies a check. Do not wait too long.
