CONFIRMATION DRIVING PATTERN
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 freeway).
• 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 4.4°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 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.
2GR-FE ENGINE CONTROL SYSTEM – SFI SYSTEM
NOTICE:
• The EVAP SYSTEM CHECK (AUTO OPERATION)
consists of 5 steps performed automatically by the
intelligent tester. 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 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 EVAP
SYSTEM CHECK, keep the temperature below 35°C
(95°F).
(a) Clear the DTCs (See page ES-45).
(b) On the intelligent tester, select the following menu items:
DIAGNOSIS / ENHANCED OBD II / SYSTEM 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 DTCs are found, the repair has been
successfully completed.
