Airbag control unit with part number 89170-06310

What does the airbag control unit 89170-06310 do?

The airbag control unit 89170-06310 is the central component of the SRS for Toyota. It processes the crash sensors, decides within milliseconds in an accident whether airbags and seatbelt pretensioners are triggered, and checks the system continuously.

If the unit detects a fault, it reports it via the airbag warning light in the instrument cluster. The sensors provide the basis for this.

After an accident, it stores crash data and locks itself.

Why does the control unit 89170-06310 fail?

The most common cause of the 89170-06310 failing is crash data stored after an accident, even if no airbag was deployed. A normal diagnostic tool cannot erase this data. Further causes are listed briefly below:

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

Only an inspection shows in the individual case which of these causes actually applies.

How can you tell that the 89170-06310 is defective?

On the 89170-06310, a defect shows mainly as the airbag warning light in the instrument cluster staying on permanently or intermittently. Fault messages in the instrument cluster and a fault memory that cannot be cleared also indicate one.
