Hello Roby68

This test also shows the described clone interface
all values ​​with OK
Despite this resistor

But your interface is OK, I think
AlfaOBD is also much less critical of the various ELM Interface

Therefore, I still think of an attitude problem!
Which driver do you have installed?

This one ?
