There are many diagnostic scanners on the market today. But most of them has only basic functionality - autel, launch, bosch or texa for sample. These scanners very good for standard daily work, but have many limitations for coding or programming car electronic modules. Other cheap OBD2 diagnostic scanners very useful only for car owners - elm327, innova, blue driver for android phones, bafX, autozone and other manufacturers. These devices (in most) can read errors only from engine ECU (diesel and gasoline). In this category you can find car diagnostic scanners for real professionals!
