Hi Martin I can't help with your problem but SCP means Standard Corporate Protocol.....Its one of Ford's own protocols they use on some of their serial communication buses based on J1850 PWM standard. If you Google it you will find plenty of details on it. It's used for both inter-ECU communication and diagnostics, i.e. a bit like CAN. The DTCs would suggest something is wrong with the SCP bus affecting comms. Possibly a wiring fault or maybe an ECU has gone faulty. You would need to see a wiring diagram and check the links.
