I had this code appear on my 2015 Lexus ES 350 & I took the car to the Lexus dealership in Overland Park, KS and all the fixes cited was not the problem. The reason for my code was simply a blown 7.5 Amp fuse under the dashboard. That was it! All fixed, no issues, just that little fuse blew out, so I suggest starting there first. Its worth your time and anxiety to start simple then move into more complex issues. I really hope that helps somebody in the future.
