Great job again George. I have no good answers directly for you, you have officially gone over my knowledge base.
We know C1185 is master relay failure. we know the position of that part, it appears (from my knowledge) to be a transistor, the big one. It must energize the coils, then the "brain" listens to the output of each coil for energy. If it is found all is good, if they fail c1185. That is all I have.
But I want to add something at this point.
Obviously with winter here, complaints have gone down significantly! Is that transistor temperature sensitive? Difficult to test, seems likely.
In my case, the fire was I believe a result of the wicking effect of the brake fluid into the connector and a short created as a result of the leakage. This is the same part the Ford has recalled in several other vehicles and will likely be in this one also, I am pretty sure they will acknowledge that soon.
We see others have found this part to be "leaky". Again, great work GEORGE!
