Read freeze frame data using an intelligent tester. Freeze frame data record the engine condition when
malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle
was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and
other data, from the time the malfunction occurred.
(a) Turn the ignition switch OFF and wait for 10 seconds.
(b) Turn the ignition switch ON.
(c) Turn the ignition switch OFF and wait for 10 seconds.
(d) Connect an intelligent tester to the DLC3.
(e) Turn the ignition switch ON and turn the tester ON.
(f)
Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CURRENT CODES.
(g) Confirm DTCs and freeze frame data.
If any EVAP system DTCs are set, the malfunctioning
area can be determined using the table below.

NOTICE:
If the reference pressure difference between the first and
second checks is greater than the specification, all the
DTCs relating to the reference pressure (P043E, P043F,
P2401, P2402 and P2419) are stored.

NOTICE:
•
The EVAP SYSTEM CHECK (AUTO OPERATION)
consists of five 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 during this operation.
•
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 the
EVAP SYSTEM CHECK, keep the temperature below
35
°C (95°F).
(a) Clear DTCs (See page
(b) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / SYSTEM CHECK / EVAP SYS
CHECK / AUTO OPERATION.
(c) After the EVAP 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 displayed, perform the
MONITOR CONFIRMATION (see "Diagnostic Help"
menu). After this confirmation, check for pending DTCs.
If no DTCs are displayed, the EVAP system is normal.

NOTICE:
•
In the EVAP SYSTEM CHECK (MANUAL OPERATION),
perform the series of 5 EVAP SYSTEM CHECK steps
manually using the intelligent tester.
•
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 during this operation.
•
When the temperature of the fuel is 35

more, a large amount of vapor forms and any check
results become inaccurate. When performing the
