NEXT -- PERFORM EVAPORATIVE SYSTEM CHECK (AUTOMATIC MODE)
36. PERFORM EVAPORATIVE SYSTEM CHECK (AUTOMATIC MODE)
NOTICE:
* The Evaporative System Check (Automatic Mode) consists of five steps performed automatically by the Techstream. It takes a maximum of approximately 19 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 in this step.
* 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 an Evaporative System Check, keep the temperature below 35°C (95°F).
(a) Clear DTCs Reading and Clearing Diagnostic Trouble Codes.
(b) On the Techstream, enter the following menus: Powertrain / Engine and ECT / Utility / Evaporative System Check / Automatic Mode.
(c) After the Evaporative System Check is completed, check for pending DTCs by entering the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.
HINT
If no pending DTCs are found, the repair has been successfully completed.

CONFIRMATION DRIVING PATTERN
HINT
After a repair, check Monitor Information (Test Result) by performing the KEY-OFF MONITOR CONFIRMATION and PURGE FLOW MONITOR CONFIRMATION described below.
1. KEY-OFF MONITOR CONFIRMATION
(a) Preconditions
The monitor will not run unless:
The vehicle has been driven for 10 minutes or more (in a city area or on a freeway)
The fuel tank is less than 90 % full
The altitude is less than 8000 ft (2400 m)
The Engine Coolant Temperature (ECT) is between 4.4°C and 35°C (40°F and 95°F)
The Intake Air Temperature (IAT) is between 4.4°C and 35°C (40°F and 95°F)
The vehicle remains stationary (the vehicle speed is 0 km/h [0 mph])
(b) Monitor Conditions
Allow the engine to idle for at least 5 minutes.
Turn the ignition switch off and wait for 5 to 10 hours.
HINT
Do not start the engine until checking Monitor Information (Test Result). If the engine is started, the steps described above must be repeated.
(c) Monitor Information (Test Result)
Connect the Techstream to the DLC3.
Turn the ignition switch to ON and turn the Techstream on.
Enter the following menus: Powertrain / Engine and ECT / Monitor / Evaporative System / Details.
Check the Monitor Information (Test Result) displayed on the Techstream.
HINT
If Incomplete is displayed, the monitor is not complete. Make sure that the preconditions have been met, and perform the Monitor Conditions again.
