Airbag control unit with part number 89170-60G80

What does the airbag control unit 89170-60G80 do?

The airbag control unit 89170-60G80 coordinates the restraint system (SRS) of Lexus. Via the crash sensors it registers what happens during an impact and, in an accident, deliberately triggers the airbags and seatbelt pretensioners that match the position of the impact.

The unit also checks its own circuitry and the interaction of the components. If it finds a fault, the airbag warning light in the instrument cluster lights up.

An accident causes crash data to be stored and the unit to lock itself. The explanations of the causes begin in the next section.

Why does the control unit 89170-60G80 fail?

With the 89170-60G80, the most common cause is crash data stored after an accident, even if no airbag has deployed. Several general causes are also possible.

Crash data cannot be removed with a usual diagnostic tool. Further causes include:

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

How can you tell that the 89170-60G80 is defective?

A defect on the 89170-60G80 shows itself through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition there may be a fault message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared. In that case, airbags and seatbelt pretensioners may not deploy in an emergency.

The light alone does not yet show whether the control unit itself is affected. Reading the fault memory answers this question.

Then have the fault memory read out, because only this result shows whether the control unit is defective or whether a connector or cable is the cause.

How does the repair of the 89170-60G80 work?
