Help with codes

I’m gonna start off by say I was never gonna buy a foreign vehicle to save my life until I was fired into buying a 2008 sequoia and since then I traded that off and bought a 2008 tundra limited. I am an abided Toyota fan probably never will buy anything else. That aside I have started have code problems been fixing most but I’m down 2. Three codes that I absolutely cannot figure out.
1. B1273 servo motor potentiometer vent circuit open toyota tundra 2008
2. U0199 Lost communication with door control module A
3. C1201-abs. Abs inlet valve LF circuit short to ground. If anybody can help with any of these I would be greatly appreciated

 

Welcome from LA (Lower Alabama)! Try posting this question in the Ask The Toyota Mechanic thread. Not everyone monitors the new intros.

Welcome. When searching you have to be brand specific. So put code with Toyota Tundra.
The b1273 is your sliding roof ecu or a short bad connection.
C1201 is usually the brake light switch or the traction control switch.
U0199 is your ecu for mirrors. Check the connections.
