J500 no communication steering rack module

[Christmas-tree-dash]

Hi all, I replaced my steering rack a few months ago and whenever I scan using vcds I get this error message.. 

However my rack is functioning fully and I have power steering with no issues.. 

All the connections are good, do these require some sort of electronic mating or coding process to function properly with the canbus system? 

 

Any help would be kindly appreciated! 

 

Thankyou
