The OBDCheck MS is specially designed to work with FORScan program for Ford, Mazda, Lincoln and Mercury vehicles. Thanks to FORScan which supports manufacturer specific protocols, you can read trouble codes from many other modules, PIDs which are not displayed by generic OBD2 scanners or applications, and run specific tests and service procedures. In one words, the combination of this adapter and FORScan can do things that regular OBD2 scanners & applications cannot do.
