VVDI MB read an EIS of a Mercedes C270 W203 2002 via OBD, and it says “Can’t start communication with EIS, check connection!”.
Try via IR, and it says “Current EIS don’t support read password via IR!”.
Here Xhorsevvdi gave the
1.Select IR mode if trying via IR
2.If the error remains, then remove EIS and read it using VVDI PROG
1)Read by soldering
2)Read by Xhorse EZS Adapter
Hope this could help!
