Possible to use the ME 9.7 on VVDI-MB? How to?

Purpose: Read Mercedes Me 9.7 ECU data

Tool: VVDI MB Tool

How to:

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.
