My 2010 is doing the same but I can clear fault for  number of miles by disconnecting Battery and fault doesn’t reappear for some time. There seems to be a great looking answer but the graphics shown kindly by Herbs is very blurred on my screen - would love to find a solution (which won’t involve an expensive trip to Lexus main dealership!) - any other suggestions would be gratefully received 😊
