Problem: I was using V2.25 Red PCB KTAG 7.020 to read Mercedes ME9.7 ECU for programming. But it failed and gave a warning: “Communication error with the ECU: control all connections; if the problem persists, send the LOG file to the assistance.”
What’s going on? Can you help me?
Solution
The reason why caused ECU communication error is because of using wrong connection interface. This interface is where to connect with ME9.7 ECM engine computer for writing data.
Original BOSCH ME9.7 ECU should be read by wiring. The wiring diagram can be found in KTAG(please click into blue link).
Updates
Now can you tell your technician to give me diagram to read with ribbon cable, please?
Engineer replied
We can offer the special wiring diagram for customers, but should replace new “help” files into KTAG.
