See: I had a very low opinion of the whole CANBUS idea, now confirmed, for the very reason that faults on it are almost impossible to locate. It is an appalling bus system to choose for reliability in a hostile environment. Something like a beefed up USB (a point to point bus, rather than muti-drop) would be much better. Then one of 30 or more nodes on it will not knock out the whole bus, and the fault can be pinpointed from the diagnostic connector. But that is just futile grumbling I suppose now. If I were MD of Ford Inc. (a bit unlikely), things would be different. 2 Quote Link to comment Share on other sites More sharing options...
glennkelly Posted December 14, 2017 Author Share Posted December 14, 2017 Got car back. They replaced the BCM and so far it’s ok. I’ll start it in a few hours when the temperature drops and then fingers crossed tomorrow morning. 1 Quote Link to comment Share on other sites More sharing options...

They just said the BCM module was replaced. Started first time this morning so I’m a very happy driver 🤪 Quote Link to comment Share on other sites More sharing options...

glennkelly Posted December 15, 2017 Author Share Posted December 15, 2017 Investigated problems starting, confirm fault carried out SBD- no recent repairs, carried out manual diagnosis, carried out wiring checks to find all ok. Checked wiring from ignition relay to BCMI, found 0.02 resistance. Contacted technical advised to fit BCMI – replaced BCMI coded up re-tested to find all ok.
