Consistent DTCs, but no warning lights

Any idea why these DTCs continue to appear?

Good morning! If you'd like to, go ahead and send us a private message with your VIN and dealer info and we'll look into this concern. Thanks!

Those ae body and serial data codes, I just checked OASIS and mine has the U053B. There is a SSM that says that unless these codes are accompanied by a warning light and additional codes, they are to be disregarded.

A while back I had an issue with my daily driver (GM not a Ford), checked the code for the issue and found a bunch of similar DTC's for communication and status errors. Took it to the dealer to get the original issue fixed and asked about all of the other messages. They said it was normal, nothing to worry about unless the CEL comes on, without an explanation why they happen. I had to do a little poking around and see why. As it turns out, some modules (that car has like 26) turn on or off before others, thus causing communication issues... usually briefly. I can actually create some of the errors... for example, sitting in the car and turn the ignition off and listening to the stereo, the module for the stereo stays on of course, but the module for the steering wheel controls is apparently off. I can control volume at the stereo no problem, but if I press the volume on the steering wheel nothing happens until I press it a second time, then it controls the volume. The first press apparently wakes up the module controlling the steering wheel controls, and in so doing generates some communication errors with several modules that are not awake that the steering wheel control module normally needs to talk to. So, yeah they are harmless unless the CEL comes on.
