C1201 and U0114 codes and no 4wd?

Good morning,

I just bought a 2015 Toyota Tundra 4wd SR5, after Hurricane Ian flooded my 2006 Tundra. I'm running into an issue where I can't get the 4wd to engage.

I took the truck to the mechanic and he gave me the codes C1201 and U0114. I've done a little research and it looks like those can be for a lot of things.

Any suggestions on where to start the diagnostics? I read the info sixweeds provided about the Transfer Case Actuator repair, but I'm not sure if that's the same for the 2015s.

Thanks for the help and advice.

Also, where do we get service manuals for tundras? I remember seeing there was some sort of toyota website you had to subscribe to?
