I know it sounds silly, but check to ensure Adaptive with Hands-Free is activated in your settings and that lane keeping system is on. (Left steering wheel button).

Is your modem communicating with FordPass? If not:

Usually when I run into modem issues, it's because the vehicle was left dead for some time, which would also explain a lot of those codes. My typical troubleshooting steps start with unhooking the negative cable for 2 min. If it doesn't resolve, I move to the TCU Fuse (#11 in the BCM Fusebox in the Passenger Footwell). If no result, then I get the vehicle to service, as TCU failure is possible, and further diag is necessary.

What do you do with the TCU fuse #11? Do you just remove it for a few minutes and put it back in, or do you replace it with a new one?
