Need to program Mercedes Benz W212 all keys lost using Launch X431 IMMO PLUS. How to connect MCU3 and x-prog3. need to solder K1 to K2 on back?
No need for a bridge, connect xprog3 to the tablet with usb and the necessary supplies to the Y obd cable and enter IMMO Prog->Mercedes Benz-> Anti-theft password reading then select the car model w212 then the wire diagram and from there you can manage, the diagram tells you exactly what joints to do and what type you have to use cable!
Notice that you need the EIS contact of the car that is put down because it is made on the bench for faster password reading!
Here is the overall connection diagram of Launch tablet, X-prog3 and MCU3 adapter.
All key lost Mercedes C class 2012 w204 – EIS.W207
No Soldering K1 K2 together, try without soldering and working.
