First, sorry for poor video. However, this should contain all the information you need.
Problem: car system does not recognize rear door was closed. Information panel in dashboard informed rear left door is open. Around internet people were telling me the door cables are probably cut. But in my case all cables were fine. Just the door latch was not positioned correctly. Unfortunately I accidentally deleted the third video clip where I demonstrated the working door. But I believe you understand the point here, you need to try that what I am doing at 0:36.
