I'm a newbie to Fords so please bear with me and many apologies for asking something which may have already been posted. (I have tried to search as much as possible but couldn't find anything)
Ok so let me try and explain what the situation is..
I have a 54 C-Max MK1 1.6 TDCI.I have owned it for a couple of months without any problems at all.
After many years of having VW's and using VCDS diagnostic software I thought I would try and get a similar version for my Ford. After looking around I stumbled onto a modified ELM cable mod.
I connected the interface to my car and tested it by reading various modules without changing or writing to any modules as it was just a test. As I wasn't changing or writing to modules I didn't backup anything (On hind sight this was a big error on my part and hopefully I'll learn from it, but I'm not sure this would have helped as I don't think the interface works correctly)
Not being convinced it was all it was cracked up to be I disconnected the cable and left it at that. Next morning I put the key in the ignition and notice that the yellow diesel glow plug light and engine management light illuminate and stay on for about 15 secs, nothing else comes on. The reverse lights, electric windows, instrument lights and instrument panel do not work until 15 seconds later. The engine starts fine if you just turn the key while these lights are on and runs perfectly.
I have tried to leave the battery disconnected overnight to see if this fixes it but unfortunately it didn't. I also tried to restore it back to original AS-BUILT settings from the Motorcraft website with my VIN number, again it didn't sort the problem out.
Everything worked fine until I plugged the interface in and read modules.
Does anyone have any ideas?
Again please accept my apologies for my waffling and inexperience.
