KT200II Read/write Dcm 3.7 ap Kia Rio JTAG Mode. 

I worked on a Marelli 9DF ECU, HW001, I did a VR read and also a bench read—both worked fine, and the write was successful. 
On HW002, I did a bench read and write, and it was also successful. 
When you have read in bench, the write can be done either on bench or in the car via OBD.
