I found some new exciting software on the market for advanced obd2 diagnostics. With these programs you can read, erase and log :
anti-lock braking system (ABS OBDii)
supplementary restriant system (SRS OBD-ii)
advanced powertrain systems like electronic transmissions, CVT (Auto OBD2)
Right now theses software packages are just available for Ford, GM and Mazda cars.
ECU scanning has come from a long way since obd1 systems.
