FORScan is a software scanner for Ford, Mazda, Lincoln and Mercury vehicles, designed to work over ELM327
There are many OBD2 scanners, but does FORScan somehow differ? Yes, because it is designed especially for Ford, Mazda, Lincoln and Mercury vehicles. So supports specific features of the manufacturer protocols, making the FORScan more powerful in work with these models than any regular OBD2 scanner.
For example, FORScan can detect modules which are not visible for regular OBD2 scanners, it can show you and reset trouble codes which are never displayed by OBD2 scanners. FORScan can show you PIDs which are not supported by any OBD2 scanner, and also run specific tests and service procedures. Version of FORScan for Windows can also perform configuration and programming functions. In other words, FORScan can do things that regular OBD2 scanners can not do.
