If I remember from other topic, you are searching for late 1990's/2000 models.
Those are first generation of digital cars so not all the sensors are available.
On my 1998 model, I can read live data with ELM scanner, but some of data turns to be bogus.
Than OBD codes are mostly for emission stuff, what is not expensive to fix, while OBD will not read transmission or more advanced codes.
If you are buying a car that has a visible problem and no CEL, you better take it on star computer.
