My son's recently acquired Mk1 Mondeo only came with one key and unfortunately not the red one so he had to get our local Ford dealer to program some new ones.
They cut two new blanks but were unable to program the PATS immobiliser because they said that their equipment (FDS 2000?) was unable to communicate with the immobiliser.
The immobiliser seems to be functioning normally because the new cut, unprogrammed keys won't start the engine. I assume that the immobiliser is part of the EEC and that the diagnostic socket is in the drivers footwell above the pedals.
Is there anyway I can check the wiring between the socket and the EEC/Immobiliser? The Ford dealer will charge £60/hour to diagnose the problem. My lad is already facing £80 for cutting and programing the new keys so I'd prefer to try and fix the fault myself. With a bit of luck it will just be a poor connection somewhere.
Any suggestions welcome.
