Airbag control unit with part number 89170-12560

What does the airbag control unit 89170-12560 do?

The airbag control unit 89170-12560 is the central control unit of the restraint system (SRS) in Toyota vehicles. It evaluates the crash sensors, decides in a crash which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

The unit indicates faults in the system via the airbag warning light, so the state of the system can be read in the instrument cluster.

After an accident, the control unit stores crash data and locks itself. This process is part of the unit's function.

Why does the control unit 89170-12560 fail?

The most common cause is stored crash data on the 89170-12560, even when no airbag has deployed. Other possible causes include aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or jump-starting

Crash data cannot be erased with a standard diagnostic tool and therefore remains in the control unit.

How can you tell that the 89170-12560 is defective?

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

In an emergency, airbags and seatbelt pretensioners may then possibly fail to trigger. The warning should therefore be taken seriously.

The warning light reports the fault itself, so you do not have to search for it laboriously.
