Airbag control unit with part number 89170-0C262

What does the airbag control unit 89170-0C262 do?

The airbag control unit 89170-0C262 is the central control unit of the restraint system for Toyota. It evaluates the crash sensors, decides within milliseconds in a crash whether airbags and seatbelt pretensioners are triggered, and monitors the system constantly.

The unit reports faults via the airbag warning light in the instrument cluster. The monitoring covers all components of the system.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 89170-0C262 fail?

The most common cause in the control unit 89170-0C262 is stored crash data after an accident, even if no airbag was triggered. Aged electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes may also be involved.

Crash data cannot be erased with a normal diagnostic tool. Airbag24 erases it during the repair.

Aged components and cold solder joints can show up under changing conditions. Moisture and corrosion attack the plug connectors, and voltage spikes arise, for example, with a weak battery or jump-starting.

How can you tell that the 89170-0C262 is defective?

Typical signs are an airbag warning light in the instrument cluster that lights up constantly or intermittently, and a fault message in the instrument cluster. Add to that a missing connection between the diagnostic tool and the control unit 89170-0C262, and a fault memory that cannot be cleared.

In an emergency, the airbags and seatbelt pretensioners may then fail to trigger. Have the system checked promptly as soon as the warning light is on.

Only reading out the fault memory shows which cause lies behind it.
