Problem with a Focus TDCI 1.8 2005

The prob is that it does not communicate the scanner with the ECU I would like to know if the communication is direct or the cables pass through some other side that communication is prevented by any problem ... thanks

Hello good day friend .. If you use a scanner with Blutooh connection, it must be close to the car to keep in the range allowed. If the connection is by cable there is no problem of how the cable is or passes as long as it is well connected to the system .. Check whether the scanner connection is of the indicated pins or if the scanner can identify the car manual or automatically, or if the scanner can read the vehicle's ECU.
