2012 mc mondeo saying immo active

[fordbossxr8]

Hi, I have a 2012 mondeo that says immo active on the dash. For the life of me I can't find a fault. Can bus wires are 60 ohms. Can talk to everything. I do need to rescan again for dtcs. Even managed to borrow pcm bcm barrel/key pats reader from another car no different. I'm at the point it's something in the wiring somewhere. Has anyone seen or heard of anything that will stop it from cranking and come up with immo active?
