Multiple issues all seem to be connected???

I have a 2017 Tundra. Check engine, vsc light came on a while back. I replaced the gas cap and the lights went off. Around the same time, the back up camera stopped coming on when I shifted into reverse. (This is intermittant, but seems to be getting worse.) I also noticed now that the PRND on the dash don't light up when I shift. This is also intermittant, and is related to the back up camera issue - when PRND lights work, the back up camera works. When PRND lights dont work, back up camera also doesnt work.

Since this started, I have taken two longer trips, 2+ hours. When I drive for long periods of time, the problem goes away - check engine light goes away, PRND lights work, back up camera works. But the next morning, all the same issues are back again. Any suggestions?

 

I got nothing. But this wiring diagram thread might be a good thread to read through
