What does the airbag control unit 89170-44060 do?

The airbag control unit 89170-44060 evaluates the crash sensors in the restraint system (SRS) of Toyota. In an accident it decides which airbags and seatbelt pretensioners are triggered, and it monitors the system continuously.

If the unit detects a fault, it is reported via the airbag warning light in the instrument cluster.

After an accident it records crash data and locks itself. The lock ends with the repair.
