Maybe it is their scanner. Try a different dealer.

Can you only see global obd2 data with your scan tool or can you also get to oem enhanced dtc’s? Do you have mode 6 capabilities on your scanner? This is extremly helpful in diagnosing misfires on fords in my experience. What codes do you have?

Look for battery voltage on pin 16 of your data link connector. If you don’t have power there, look at fuse 105 in the under hood fuse block. I have a Mitchell diagram that says it should be a 30 amp fuse. That sounds a little high to me for a circuit that’s part of the computer data circuitry so verify that one for yourself if you’ve got your own manuals handy.
