2018 Tundra Help

Hi everyone new here.

Question! I have these sensors going off as well as check engine light that’s making me pretty concerned, it comes on and off some days nothing and then it’s on again. It’s making concerned. I took it in and of course by the time it went to the shop it wasn’t on. The mechanic reset and said bring it back in but he thinks somethings array with the transmission and wants to drop the pan and check for chunks, any ideas what may be causing this?
I stole these pics from another just for example.

 

There's a TSB for the trailer brake controller. Searching here should find it if your mechanic can't.

 

Have you done any suspension work or anything else recently?

When I changed my suspension and lifted the front, the sensors weren't happy and gave me similar errors. I got my alignment and reset the battery and all my errors went away.

Not saying you don't have the above issue, but just pointing out another possibility.

 

There's one for the TSS sensor also, Pre-Collision System. If it wasn't done already. Could be just a dirty emblem.

 

The only thing done recently was a new windshield and I have used the hitch for towing.

 

Throwing this out there....when was the battery last replaced? Maybe check volts and load test.

Tundras can do weird electronic alerts when the volts are lower than the systems need. Worth a look, seen more than a few different, odd alerts on tundras when the battery was starting to take a crap, especially when it is different and seemingly unrelated electronic systems that occur at once.
