Hand–held Tester
NOTICE:
Hand–held tester only: When the diagnostic system is
switched from the normal mode to the check mode, it
erases all DTCs and freeze frame data recorded in normal
mode. So before switching modes, always check the DTCs
and freeze frame data, and note them down.

NOTICE:
When simulating symptoms with an OBD scan tool (ex-
cluding hand–held tester) to check the DTCs, use normal
mode. For codes on the DTCs chart subject to "2 trip detec-
tion logic", turn the ignition switch OFF after the symptom
is simulated the 1st time. Then repeat the simulation pro-
cess again. When the problem has been simulated twice,
the CHK ENG is indicated on the instrument panel and
DTCs are recorded in the engine and ECT ECU.

INSPECT DIAGNOSIS (Normal Mode)
Check the CHK ENG.
(1) The CHK ENG comes on when the ignition switch
is turned ON and the engine is not running.
(2) When the engine is started, the CHK ENG should
go off. If the lamp remains on, the diagnosis system
has detected a malfunction or abnormality in the
system.
Check the DTC.
(1) Prepare an OBD scan tool or hand–held tester.
(2) Connect the OBD scan tool or hand–held tester to
the DLC3 at the lower of the instrument panel.
(3) Turn the ignition switch ON and push the OBD scan
tool or hand–held tester switch ON.
(4) Use the OBD scan tool or hand–held tester to check
the DTCs and freeze frame data and note them
down (For operating instructions, see the OBD scan
tool's instruction book).
(5) See page DI–74 to confirm the details of the DTCs.
