isetta Posted July 15, 2019 Share Posted July 15, 2019 I don't know anything about the KA nor where the BCM is. But I can say that on these modern cars with BCM etc just one bad connection on a plug or an earthing point can cause all sorts of odd electrical behaviour when the electricity tries to find another route. I was recently working on a car and found that without the key in the ignition the dash lit up when I unscrewed an earth point to clean it up.

isetta Posted July 17, 2019 Share Posted July 17, 2019 in case it helps, on the Focus I was working on there were earthing points on the door steps/inner sill- remove plastic trim alongside the door rubber seal. On the passenger side there were three earthing points and on the drivers side two of them (bolts with 10mm head). I have no idea where they might be on yours as I think your car is Fiat built isn't it? But it does go to show how these earthing points can be hidden away in a place where you might not suspect them to be. Quote Link to comment Share on other sites More sharing options...
