37 PERFORM EVAP SYSTEM CHECK(AUTO OPERATION)
NOTICE:
In the EVAP SYSTEM CHECK (AUTO OPERATION), the series of 5 EVAP SYSTEM CHECK steps
is performed automatically. It takes a maximum of approximately 18 minutes.
Do not perform the EVAP SYSTEM CHECK when the fuel tank is more than 90% full because
the cut-off valve may be closed, making the leak check of the fuel tank unavailable.
Do not run the engine in this step.
When the temperature of the fuel is 35C (95F) or more, a large amount of vapor forms and any
check results become inaccurate. When performing an EVAP SYSTEM CHECK, keep the tem-
perature below 35C
(95F).
(a) Clear DTCs (see page 05-38).
(b) On the hand-held tester, select the following menu items: DIAGNOSIS / ENHANCED OBD II / SYS-
TEM CHECK / EVAP SYS CHECK / AUTO OPERATION.
(c) After the SYSTEM CHECK is completed, check for pending DTCs by selecting the following menu
items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / PENDING CODES.
HINT:
If no pending DTC is found, the repair has been successfully completed.

Monitor Confirmation
HINT:
After a repair, check Monitor Status 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 free way)
The fuel tank is less than 90% full
The altitude is less than 8,000 ft (2,400 m)
The Engine Coolant Temperature (ECT) is between 4.4C and 35C (40F and 95F)
The Intake Air Temperature (IAT) is between 4.4C and 35C (40F and 95F)
The vehicle remains stationary (the vehicle speed is 0 mph [0 km/h])
(b) Monitor Conditions
(1) Allow the engine to idle for at least 5 minutes.
(2) Turn the ignition switch OFF and wait for 6 hours (8 or 10.5 hours).
HINT:
Do not start the engine until checking MONITOR STATUS. If the engine is started, the steps described above
must be repeated.
(c) Monitor Status
(1) Connect a hand-held tester to the DLC3.
(2) Turn the ignition switch ON and turn the tester ON.
(3) On the tester, select the following menu items: DIAGNOSIS / ENHANCED OBD II / MONITOR
STATUS.
(4) Check the Monitor Status displayed on the tester.
HINT:
If INCMP is displayed, the monitor is not completed. Make sure that the preconditions have been met, and
perform the Monitor Conditions again.
2. PURGE FLOW MONITOR CONFIRMATION (P0441)
HINT:
Perform this monitor confirmation after the Key-Off Monitor Confirmation shows COMPL (complete).
(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 free way)
The ECT is between 4.4C and 35C (40F and 95F)
The IAT is between 4.4C and 35C (40F and 95F)
(b) Monitor Conditions
(1) Release the pressure from the fuel tank by removing and reinstalling the fuel tank cap.
(2) Warm the engine up until the ECT reaches more than 75C (167F).
(3) Increase the engine speed to 3,000 rpm once.
(4) Allow the engine to idle and turn A/C ON for 1 minute.
(c) Monitor Status
(1) Turn the ignition switch OFF (where ON or the engine is running).
(2) Connect a hand-held tester to the DLC3.
(3) Turn the ignition switch to ON and turn the tester ON.
(4) On the tester, select the following menu items: DIAGNOSIS / ENHANCED OBD II / MONITOR
STATUS.
(5) Check the Monitor Status displayed on the tester.
