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.
