There are numerous ECUs on the UZZ32s. Toyota calls most “computers”, some “sensors” and one a “integration relay”. These components are typically housed in plastic or metal cases located throughout the vehicle. Some are also “hidden” and integrated with larger components such as eg the dash, EMV etc.
