VVDI MB BGA Tool Benz professional key programmer,and try to connect with ME 9.7,but failed,what is the solution?
Problem suggestion:
Connect ME97 to read data from ECU, did not try to reset. Check the scheme of connection.
Connect VVDI MB Tool to ECU directly with ECU with power supply. Every function is fine. If you use Benz ECU test adapter cable, please check the can high and can low of the plug wehtehr is short circuit. Sometimes there will be short circuit on the serial port of the ECU adapter.
