In terms of terminology.. it's a flipping nightmare isn't it!!.. almost like nobody was in control/had any authority/cared...Thank you Hamed. So, I could stop working on that CCF part. I will check, if I already have these rar-files. And I will go for reconfiguration .
GWM is the Gateway Module. Placed directly beneth the RJB. Labeled with GWM. GSM is the Gearshift module. BCM (Body control module) is the name in SDD for the CJB (central junction box). BCMB (body control module B) is the name in SDD for the RJB (rear junction box) in the trunk. Horrifying!! Why do they have 2 or 3 names for one module?
