What is the difference between Generic and Enhanced data?
US Federal law required all vehicle manufacturers to meet OBD II standards by 1996. All OBD II vehicles support a common list of emission-related data called Generic data. This data includes basic powertrain parameters such as engine RPM, vehicle speed, engine coolant temperature, etc. Vehicle manufacturers wanted to be able to scan more data than just the generic parameters so they added their own expanded list of Enhanced data (also called factory or dealership data). This data is wide-ranging and covers areas such as; Powertrain, ABS, Airbag, and Body Controllers, etc.
