Make sure everything in the car is turned off. Climate, radio, etc. Open and close the door so the accessories go off. Press and hold the start button with your foot off the brake and within a few seconds, the gauges will sweep. Then you should be ready. Do not touch anything during the load. It will tell you when to turn it off or on. When it says turn the car on, hold the button with foot off brake. At the point you are ready to load the tune, the gauge may not sweep. In mine, '12, the collision light starts blinking while the tune loads. The bliss may flash too.
