This should be better image. So i need to check pins 6 and 14 (not 4 and 16?) and if there be 120 Ohm i should remove which rezistence? And what is this MCP2551? Cuz when i plug this to my car i can chcek only ecu. On other moduls i have this message.

Hi i Have problem with my ELM which resistor i should remove R4 or R14. All test give OK result, so i need to only remove, but which:)?
