Lancer ralliart problems

[Snickers46]

Hi guys not sure where i should put this as ive only just joined. Long story short i had low voltage issue with my ABS pump on my 2010 lancer ralliart. Got a reconditioned pump today and had it fitted. Low voltage now gone but im getting an error on cant find control unit on 4wd, diff and power steering. Diagnostic machine at work not a cheap one either. Doesnt give codes for the problems either. Anybody any ideas as im now just wanting rid of it.
