When I connect a dianostic tool to my truck. It doesn't connect/ read that its connected on the screen. I tried it on another yukon and it worked just fine. Could it Be a fuse or do I need another connecter. Or !
have the same problem?

Is your check light coming on with the ignition? If so I would clean the OBD connector with contact cleaner and if still no connection, try a different scanner.
