hi can anyone give me a plan of the earthing locations on C-max 2011, as the saga continues got a lot of various body fault codes, I'm not sure they are faults but feel its an earthing issue, checked the battery to body lead/connector that needed cleaning, as in other post this car has had a lot of water inside it, looking inside it there are lots of rusty spots, (sadly just put all the rear trims back in place as iwaited to check that rain wasn't getting in, now need to remove again to check rear fuse box earthing)

    I'd be suspecting internal water damage in the BCM

    I had a terrible time finding why my Cmax had so many sporadic errors. This may help you.
