Looks like this was done here, but just pull the part and replace.
This is cross posted on another forum as well, but I went to start my truck today and out of nowhere I got all three of these messages popping up at once. Everything runs and drives fine so I am scratching my head. Just a glitch perhaps, I am going to unhook the battery tomorrow and let it sit...

Here's some more detail on this thread... issue seems to be oil leaking on the wire harness, which btw could be mine as the oil filter was loose from recent oil change and dripping in this area described below. I will check this out.
Just had these three pop up while driving on the freeway. Truck has the Maximum Care Extended Warranty (Just hit 60k miles). Anyone every have all 3 of these pop up at once? Its going to the dealer once I call them on Monday. As luck has it, this happened after 5pm on a Saturday.

Also in this thread as well the 4wd actuator.
Hopefully this post will help others in the future.
Now just to determine if a test can be done on it at the house versus a trip to the dealer....

The dealer will likely do some basic troubleshooting. One thing I saw as a note on the work order is they measure resistance on circuit G303 between the DTCM and actuator. It should read 3.0 ohms. Mine was reading .4 ohms so they knew it was bad. I don’t know the details on how or where to measure that circuit but if you are technically inclined maybe you could do this. That or just replace the actuator and be done with it. It’s been the reason for these 3 codes on nearly every persons truck that I’ve seen.
