Hello all,

I have a xf that when I got it the car was having issues caused by fried modules under passanger seat. I have replaced the tpms, dynamic contol and the climate control for the seats. I keep getting lost communication with control module B. I have also tried to add keys using sdd but it never takes the new ones. Just the old. We'll I decided to replace the rear body fuse block in the truck and now I have no keys working, multiple systems are showing as not connected and car will not do anything. I put the old module back seeing if it will let the fob start the car but still won't. So what have I done and how to fix. I have windows 10 running sdd with a mongoose pro cable.

Help.

 

Go to pre delivery inspection and run that on the SDD, make sure you have a battery tender on it,and make it sure it is green on the bar on the right top corner ,also have all keys in the car
