So confused I have got the software and installed into my computer, also bought myself a cable that connects to my pc ethernet port and is ODB plug on the other end , is their any other "hardware" that needs to be used in order to use ISTA/D just for clearing and reading errors ? I have connected via my ethernet port and it reads the VIN also says no errors, but the car tells me "Driveatrain Faulty DO NOT DRIVE" I need to find out what this error is but might be missing something here, thanks for your help guys
