This is a short video to show you how to get the HVAC (air conditioner) diagnostic codes for your late model Toyota or Lexus vehicle or truck. This video shows the procedure on a 2017 LX570, but the same procedure will work on most Toyota and Lexus vehicles that have an "Auto" button and a digital temperature readout. Including Camry, Tundra, Celica, Corolla, Tacoma, 4runner, gX470, GX460, LX470, Land Cruiser, LS460, GS460, and other models.
