Airbag control unit with part number 89170-06241

What does the airbag control unit 89170-06241 do?

The airbag control unit 89170-06241 is the central control unit of the restraint system (SRS) for Toyota. It evaluates the signals from the crash sensors, triggers airbags and seatbelt pretensioners in an emergency and monitors the system continuously.

The decision in a collision is made within milliseconds. The unit reports detected faults via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself.

Why does the control unit 89170-06241 fail?

The most common cause on the 89170-06241 is crash data stored after an accident, even if no airbag was deployed; a normal diagnostic tool cannot erase it. Other possible causes are aged components, moisture at plug connections and voltage spikes.

Further causes at a glance:

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

How can you tell that the 89170-06241 is defective?

A defect in the 89170-06241 shows up as the airbag warning light in the instrument cluster, as an error message there, as a missing connection to the diagnostic tool or as a fault memory that cannot be cleared. In that case the airbags and seatbelt pretensioners may not deploy in an emergency.

Typical signs:

• airbag warning light that stays on permanently or intermittently
• error message in the instrument cluster
• diagnostic tool unable to connect to the control unit
• fault memory that cannot be cleared

It is therefore worth having it checked promptly.
