Both Xhorse VVDI Prog and Multi Prog will read and write Delphi MT62.1 ECU for Changan, BAIC, Dongfeng car brands.
Here is the wiring diagram to this ECU.
The key point to note is that the yellow RESET wire must not be connected to the position marked on the board. The specific correct position has been indicated in the diagram.
Otherwise may fail to read this ECU with vvdi prog.
