so with the launch, lets hook it up and go through screen by screen together.

lets make sure we are selecting the proper car and model and trans .

all seems good man if you have that voltage at the can connection, and you have power and ground at the module.

you should have communication.

I’m trying scanning with the two different computer
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 4 months ago
I would like to see these computers. If you have power and ground and the voltage on the can wires then you should be able to communicate . So we either are choosing the wrong car or the scanners are not good enough or the module is bad but you said you replaced it already correct?
