Confirmation Driving Pattern

NOTE:
  • The Evaporative System Check (Automatic Mode) consists of 6 steps performed automatically by the Techstream. It takes a maximum of approximately 24 minutes.
  • Do not perform the Evaporative System Check when the fuel tank is higher than 85% 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 higher, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature less than 35°C (95°F).
  1. Connect the Techstream to the DLC3.
  2. Turn the engine switch on (IG).
  3. Turn the Techstream on.
