VVDI MB BGA Tool failed to connect to ME 9.7 (solved)

I want to connect to ME 9.7 with Mercedes-Benz VVDI MB BGA tool on the bench. I have everything connected. Am I missing something?

Customer solution:

ME97 connected to data read from ECU, did not try to reset. Check the scheme of connection.

Connect the cables from VVDI MB tool OBD to ECU directly and give power supply. Every function is fine. If you using Benz ECU test adapter cable, please check did the can high and can low of the plug is short circuit. Some times there will have short circuit on the serial port of the ECU adapter.
In my case I’m not using resistance.
