2. Normal Mode:
DTC CHECK
NOTICE:
Hand-held tester only:
When the diagnostic system is switched from the normal
mode to the check mode, all the DTCs and freeze frame
data recorded in the normal mode will be erased. So before
switching modes, always check the DTCs and freeze frame
data, and note them down.
(a) Checking DTCs using the OBD II scan tool or hand-held
tester.
(1) Connect the OBD II scan tool or hand-held tester
to DLC3.
(2) Turn the ignition switch ON.
(3) Use the OBD II scan tool or hand-held tester to
check the DTCs and freeze frame data and note
them down (For operating instructions, see the
OBD II scan tool's instruction book).
(4) See page DI-381 to confirm the details of the
DTCs.
NOTICE:
When simulating symptoms with an OBD II scan tool (ex-
cluding hand-held tester) to check the DTCs, use the nor-
mal mode. For codes on the DTCs chart subject to º2 trip
detection logicº, 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 is indicated on the instrument panel and
DTCs are recorded in the ECM.
(b) When using the OBD II scan tool or hand-held tester:
Clearing the DTCs.
(1) Connect the OBD II scan tool or hand-held tester
to DLC3.
(2) Turn the ignition switch ON.
(3) When operating an OBD II scan tool (complying
with SAE J1978) or hand-held tester to erase the
codes, the DTCs and freeze frame data will be
erased. (See the OBD II scan tool's instruction book
for operating instructions.)
(c) When not using the OBD II scan tool or hand-held tester:
Clearing the DTCs.
(1) Disconnecting the battery terminal or remove the
EFI and ETCS fuse from engine room J/B for 60 se-
conds or more.

(6) Start the engine. The MIL should turn off after the
engine starts.
(7) Simulate the conditions of the malfunction de-
scribed by the customer.
(8) After simulating the malfunction conditions, use the
hand-held tester diagnosis selector to check the
DTC, freeze frame data and other data.
(9) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clearing DTCs using the OBD ll scan tool or the hand-
held tester.
(1) Connect the OBD ll scan tool or the hand-held tes-
ter to the DLC3.
(2) Turn the ignition switch ON.
(3) 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.
(c) Clearing the DTCs without using the OBD ll scan tool or
the hand-held tester.
Remove the EFI or ECD No. 1 and ETCS fuses from the
engine room J/B for more than 60 seconds, or disconnect
the battery terminal for more than 60 seconds.
After disconnecting the battery terminal, perform the ºINI-
TIALIZEº procedure.

The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.
