Airbag control unit with part number 89170-02S60

What does the airbag control unit 89170-02S60 do?

The airbag control unit 89170-02S60 controls the restraint system (SRS) in Toyota vehicles. It evaluates the crash sensors, determines in an accident which airbags and seatbelt pretensioners trigger, and checks the system continuously. It shows faults via the airbag warning light.

While driving, the electronics remain active and monitor the connected components. The result appears in the instrument cluster as soon as a deviation occurs.

After an accident, it stores crash data and locks itself. The control unit is therefore the central point where the system comes together.

Why does the control unit 89170-02S60 fail?

The most common cause of the 89170-02S60 is an accident record: crash data stays stored even if no airbag has triggered, and a normal diagnostic tool cannot remove it. In addition, ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes come into question.

The crash data remains in the unit until it is removed during the repair.

Ageing electronic components and cold solder joints are typical weak points of a control unit.

Voltage spikes, for example from a weak battery or a jump start, can load the electronics, as can moisture and corrosion.

How can you tell that the 89170-02S60 is defective?

With the 89170-02S60, the airbag warning light in the instrument cluster is the most important warning sign. In addition come a diagnostic tool without a connection and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may fail to trigger.

• The warning light stays on permanently.
• It appears only intermittently.
• A fault message is shown in the instrument cluster.
• The diagnostic tool cannot reach the control unit.
• The fault memory cannot be emptied.

Have such signs checked promptly by a specialist workshop.
