KESS V2 5.017 KSUITE 2.53 “EXTERNAL EXCEPTION EEFFACE” ERROR SOLUTION

Customer problem: When I run Ksuite 2.53 on my KESS V2 Master, a message error appeared on the screen “External exception EEFFACE”. I tested with another cable and tested on another port… but the results were always the same. It is normal for the computer to detect as usb device. I also tried to take sd card out and put back, and cleaned the sd card and reader contracts, but also failed to solve.
