Hello, I have a Cadillac Escalade ESV, everything works fine, the only problem is with the rear trunk. I cannot open the trunk with the remote when the key is off. it only works when i turn on the power key. I tried replacing another trunk control box and still having the same problem. I am trying to run the Liftgate control box program again but don't know which software can support the 2006 model. I have GDS2, GM PDS
