Airbag control unit with part number 89170-06B30

What does the airbag control unit 89170-06B30 do?

The airbag control unit 89170-06B30 controls the restraint system (SRS) of Toyota. It evaluates the signals from the crash sensors and decides within milliseconds in an accident which airbags and seatbelt pretensioners are triggered.

During operation it monitors the components of the system. If it detects a fault, it shows it via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself.

Why does the control unit 89170-06B30 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Other causes include aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The control unit creates crash data as soon as it detects an accident and then keeps it in memory.

The other causes act over a longer period. Electronic components age, moisture attacks plug connections, and cold solder joints or corrosion impair the contact.

Voltage spikes arise, for example, from a weak battery or when a jump start is connected, and put strain on the electronics.

How can you tell that the 89170-06B30 is defective?

The airbag warning light lights up permanently or intermittently, a fault message appears in the instrument cluster, or the diagnostic tool cannot find the control unit. A fault memory that cannot be cleared is a further sign. In that case airbags and seatbelt pretensioners may not deploy in an emergency.

These signs are:

• Airbag warning light on permanently or intermittently
• Fault message in the instrument cluster
• No connection between the diagnostic tool and the control unit
• Fault memory cannot be cleared

The warning light shows the fault as soon as the system detects it. A lit indicator should therefore be clarified promptly.
