I’m tested reading/writing ECU sid305 via OBD 100% working with ECUHELP KT200. First, read the password, then read/write ECU by following the instruction.
Here is the instruction to follow, when you run KT200, click on “Info” and you will get the guide.
Alright, hope it helps. Any questions about using ECUHELP KT200 to read/write sid305 via OBD, please contact us at Whatsapp: http://wa.me/8618205996549.
