Airbag control unit with part number 89170-06870

What does the airbag control unit 89170-06870 do?

As a control unit, the airbag control unit 89170-06870 runs the restraint system (SRS) of Toyota. It checks the crash sensors, determines in an accident within fractions of a second which airbags and seatbelt pretensioners to trigger, and monitors the system continuously. After an accident it stores crash data and locks itself.

The electronics evaluate the sensor signals continuously. Detected faults end up in the fault memory and are reported via the airbag warning light.

Why does the control unit 89170-06870 fail?

The most common cause is a crash data record after an accident, even without a deployed airbag; a normal diagnostic tool cannot remove it. Other causes include ageing components, cold solder joints, moisture and corrosion on connectors, and voltage spikes.

Crash data is created even when no airbag fires. With this control unit, Airbag24 removes it during the repair.

In addition, these causes are possible:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

How can you tell that the 89170-06870 is defective?

The airbag warning light in the instrument cluster may light up permanently or intermittently; in addition, an error message appears in the instrument cluster. Furthermore, the diagnostic tool cannot establish a connection to the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The light comes on as soon as the unit detects a fault, and depending on the fault it stays on or flickers.

A defect therefore does not stay hidden; it is visible in the instrument cluster.

Two things need to be done before removal. Comparing the part number on the label of the unit with this page gives certainty that you have the right unit. Having the fault memory read out, on the other hand, shows whether the control unit is defective or whether a connector or cable is affected.
