Start diagnosisFault memories on this car (if it has a CAN bus — roughly 2008 and newer) are read by the program with an ordinary ELM327 adapter too. A K+DCAN cable (E series) or ENET cable (G series) in the Windows version is what unlocks dealer-level depth: coding, service intervals, factory options, per-module mileage and the full fault list for every unit in the table above.
