DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
• Perform DTC CONFIRMATION PROCEDURE when the fuel is between 1/4 and 3/4 full, and vehicle is
placed on flat level surface.
• Always perform test at a temperature of 5 to 60
°C (41 to 140°F).
• Cool the vehicle so that engine coolant temperature becomes same level as ambient temperature.
Do you have CONSULT
YES
>> GO TO 2.
NO
>> GO TO 4.
2.
PERFORM DTC CONFIRMATION PROCEDURE A
With CONSULT
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.
3. Check that the following condition are met.
FUEL T/TMP SE: 0 - 35
°C (32 - 95°F)
4. Start the engine and wait at least 60 seconds.
5. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
.
NO
>> GO TO 3.
3.
PERFORM DTC CONFIRMATION PROCEDURE B
With CONSULT
1. Start the engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Turn ignition switch ON.
4. Select “PURG VOL CN/V P1444” of “EVAPORATIVE SYSTEM” in “DTC WORK SUPPORT” mode of
“ENGINE” using CONSULT.
5. Touch “START”.
6. Start the engine and let it idle until “TESTING” on CONSULT changes to “COMPLETED”. (It will take
approximately 10 seconds.)
If “TESTING” is not displayed after 5 minutes, retry from step 2.

PURG VOLUME CONT/
V
(EVAP canister purge
volume control solenoid
valve)
A
The canister purge flow is detected during
the vehicle is stopped while the engine is
running, even when EVAP canister purge
volume control solenoid valve is completely
closed.
• EVAP control system pressure sensor
• EVAP canister purge volume control sole-
noid valve
(The valve is stuck open.)
• EVAP canister vent control valve
• EVAP canister
• Hoses
(Hoses are connected incorrectly or
clogged.)
B
The canister purge flow is detected during
the specified driving conditions, even when
EVAP canister purge volume control sole-
noid valve is completely closed.
