Note. The Evaporative System Check (Automatic Mode) consists of 9 steps performed automatically by the Techstream. It takes a maximum of approximately 18 minutes. Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable. Do not run the engine during this operation. When the temperature of the fuel is 35°C (95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature below 35°C (95°F).
