Xhorse VVDI Prog FRM ‘Lost OBD Communication’ Solution

 Problem:

In this E series FRM XDT256 model, after making a copy of the EEPROM and FLASH with xhorse vvdi prog, I have a ‘Lost OBD communication’ error. Any solution?

Solution:

FRM Repair Method:

Remove FRM, check data with VVDI Prog, if all data are blank (FF), then write data to the MCU.

First disassemble the FRM and use VVDI PROG to check its data. If the data is empty (FF), then you only need to re-write data into it.

Some cars can be repaired directly after writing the data, If there is a deviation, for example, if the vehicle model is similar but the data is different, then you will need to perform FRM coding with universal scanners (i.e Launch X431).
