DTC CHECK/CLEAR
NOTICE:
If no DTC appears in normal mode:
On the OBD II scan tool or the hand-held tester check
the pending fault code using the Continuous Test Re-
sults function (Mode 7 for SAE J1979).
When the diagnosis system is changed from normal
mode to check mode or vice-versa, all DTCs and
freeze frame data recorded in normal mode will be
erased. Before changing modes, always check and
make a note of DTCs and freeze frame data.
1. CHECK DTC (Using the OBD II scan tool or hand-held
tester)
(a) Connect the OBD II scan tool or hand-held tester to the
DLC3.
(b) Turn the ignition switch ON.
(c) Use the OBD II scan tool or the hand-held tester to check
the DTCs and freeze frame data and then write them
down.
For the hand-held tester, enter the following menus:
DIAGNOSIS / ENHANCED OBD II / DTC INFO / CUR-
RENT CODES. For the OBD II scan tool, see its instruc-
tion manual.
(d) See page 05-48 to confirm the details of the DTCs.
NOTICE:
When simulating a symptom with the OBD II scan tool (ex-
cluding hand-held tester) to check for DTCs, use the nor-
mal mode. For DTCs subject to º2 trip detection logicº, per-
form either of the following actions.
Turn the ignition switch OFF after the symptom is
simulated once. Then repeat the simulation process
again. When the problem has been simulated twice,
the MIL illuminates and the DTCs are recorded in the
ECM.
Check the pending fault code using the Continuous
Test Results function (Mode 7 for SAE J1979) on the
OBD II scan tool.
2. CLEAR DTC (Using the OBD II scan tool or hand-held
tester)
(a) Connect the OBD II scan tool or the hand-held tester to
the DLC3.
(b) Turn the ignition switch ON.
(c) Erase DTCs and freeze frame data with the OBD II scan
tool (complying with SAE J1978) or the hand-held tester.
For the hand-held tester: 1) enter the following menus:
DIAGNOSIS / ENHANCED OBD II / DTC INFO / CLEAR
CODES; and 2) press YES. For the OBD II scan tool, see
its instruction manual.

INSPECTION PROCEDURE
NOTICE:
A hand-held tester is required to conduct the following diagnostic troubleshooting procedure.
HINT:
Using hand-held tester monitor results enables the EVAP (Evaporative Emission) system to be con-
firmed.
Read freeze frame data using a hand-held 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.
1 CONFIRM DTC
(a) Turn the ignition switch OFF and wait 10 seconds.
(b) Turn the ignition switch ON.
(c) Turn the ignition switch OFF and wait 10 seconds.
(d) Connect the hand-held tester to the DLC3.
(e) Turn the ignition switch ON and press the hand-held tester switch ON.
(f) Enter the following menus: DIAGNOSIS/ ENHANCED OBD II/ DTC INFO/ CURRENT CODES.
(g) Confirm the 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 0.02 inch reference pressure difference between the first and second checks is greater than
the specification, the DTCs corresponding to the reference pressure (P043E, P043F, P0441, P0455,
P0456, P2401, P2420) will be all stored.

2 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 and 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 the 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 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 DTC is displayed, perform the Monitor Confirmation after this repair is completed. After this
confirmation, check for pending DTCs. If no DTC is displayed, the EVAP system is normal.

NOTICE:
In the EVAP SYSTEM CHECK (MANUAL OPERATION), the series of 5 EVAP SYSTEM CHECK
steps is performed manually.
Do not perform the EVAP SYSTEM CHECK when the fuel tank is more than 90% full because
the cut-off valve may be closed and 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
