Other ECUs

There are numerous ECUs on the UZZ32s. Toyota calls most of them “computers”, and many of these are in separate plastic cases distributed around the vehicle. Toyota also calls some of them (eg the light failure module) a sensor. Some are also part of what we think of as broader components, eg the dash, EMV etc.
