Hello cerasaro

What car and what control you want to read?
But according to your description, this is the known CAN bus problem

We have described here several times.

Remove the yellow resistance and your interface will work

after I removed the resistance will still work on the engine control unit?

I would like to use it a bit with all the cars

I bought the 3 cables adapters

after removing the resistance work?

Hello

For this reason I asked for the vehicle and mj
without any information about you, unfortunately I can only rate what problem you have

Only when I know your vehicle I can write to you which adapter you need
or if you ever need an adapter

I'm not a magician
