can't communicate with vsm to program!
 

Hey dudes and dudets,
Have 2004.5 ford f350 with sct tuner,diesel 6.0. Cant communicate with vsm via the obd connector. Some of the vsm features not working. Door ajar light not working,auto locks not working,stereo won't turn off,light sensor not working, no dome lights. alarm system does work.
Installed new vsm and took to stealership for them to tell they can't program it. no connection to vsm via obd. But i can connect to cluster which i had serviced. Not sure what problem is? Any ideas out there? Please HELP!!!!! Thanks
