The vehicle's ECM uses the ISO 9141±2 (Euro±OBD)/
ISO 14230(M±OBD) communication protocol. The termi-

mat.

HINT:
If the display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of the hand±held tester to
the DLC3, turned the ignition switch ON and operated the
hand±held tester, there is a problem on the vehicle side or tool
side.

If communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.

If communication is still impossible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool's instruction manual.
(d) Inspect the battery voltage.
Battery voltage: 11 to 14 V
If voltage is below 11 V, recharge the battery before proceeding.
(e) Check the CHK ENG.
(1) The CHK ENG lamp comes on when the ignition
switch is turned ON and the engine is not running.
HINT:
If the CHK ENG is not illuminated, troubleshoot the combination
meter.
(2) When the engine is started, the CHK ENG should
go off. If the lamp remains on, it means that the diag-
nosis system has detected a malfunction or ab-
normality in the system.
2. DTC CHECK (Normal Mode)
NOTICE:
Hand±held tester only:
When the diagnosis system is switched from the normal
mode to the check (test) mode, it erases all DTCs and freeze
frame data recorded in the normal mode. So before switch-
ing modes, always check the DTCs and freeze frame data,
and note them down.

(a)Checking the DTCs using the hand±held tester. (1)Connect the hand±held tester to the DLC3.
(2)Turn the ignition switch ON and switch the hand±held tester main switch ON.
(3)Use the hand±held tester to check the DTCs and freeze frame data and note them down (for operat-
ing instructions, see the hand±held tester's instruc-
tion book).
(4)See page 05±309 to confirm the details of the DTCs.
HINT:
In the event that 2 or more DTCs are detected, the CHK ENG
lamp will indicate the smaller number DTC first.
(b) Clearing the DTCs using the hand±held tester. (1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) When operating the hand±held tester to erase thecodes, the DTCs and freeze frame data will be
erased. (See the hand±held tester's instruction
book for operating instructions.)
(c) Clearing the DTCs not using the hand±held tester. (1) Disconnect the battery terminal or remove the EFIand THROTTLE fuses from the engine room R/B
No. 1 for more than 60 seconds.
3. DTC CHECK (Check Mode)
HINT:
Hand±held tester only:
Compared to the normal mode, the check mode has more sens-
ing ability to detect malfunctions.
Furthermore, the same diagnostic items which are detected in
the normal mode can also be detected in the check (test) mode.
(a) Procedure for check mode using the hand±held tester.
(1) Check the initial conditions

Battery positive voltage 11 V or more.

Throttle valve fully closed.

Transmission in the ºPº or ºNº position.

Air conditioning switched OFF.
(2) Turn the ignition switch OFF.
(3) Connect the hand±held tester to the DLC3.
(4) Turn the ignition switch ON and switch the hand±
held tester main switch ON.

CIRCUIT DESCRIPTION
The park/neutral position switch goes on when the shift lever is in the N o\

is moved from the N position to the D position, this signal is used for \
air±fuel ratio correction and for idle speed
control (estimated control), etc.

* 2 trip detection logic
When a logic malfunction is first detected, the pend-
ing fault code is stored in the ECM memory (1st trip).
If the same malfunction is detected again during the
second drive test, this second detection causes the
CHK ENG to illuminate (2nd trip) (However, the igni-
tion switch must be turned OFF between the 1st trip
and 2nd trip).

Freeze frame data:
The freeze frame data records the engine condi-
tions (fuel system, calculator load, engine coolant
temperature, engine speed, vehicle speed, etc.)
when the malfunction is detected. When trouble-
shooting, it is useful for determining whether the ve-
hicle was running or stopped, the engine was
warmed up or not, etc. at the time of the malfunc-
tion.

Priorities for troubleshooting:
If troubleshooting priorities for multiple DTCs are
given in the applicable DTC chart, these should be
followed.
(b) Check the DLC3.
The vehicle's ECM uses the ISO 9141±2(Euro±OBD)
communication protocol. The terminal arrangement of
the DLC3 complies with ISO 15031±03 and matches the
ISO 9141±2 format.

3. DTC CHECK (Check Mode):
HINT:
Hand±held tester only:
Compared to the normal mode, the check mode has more sens-
ing ability to detect malfunctions. Furthermore, the same diag-
nostic items which are detected in the normal mode can also be
detected in the check mode.
(a) Procedure for Check Mode using the hand±held tester.
(1) Check the initial conditions.

Battery positive voltage 11V or more.

Throttle valve fully closed.

Transmission in the ºNº position.

A/C switched OFF.
(2) Turn the ignition switch OFF.
(3) Connect the hand±held tester to the DLC3.
(4) Turn the ignition switch ON and switch the hand±
held tester main switch ON.
(5) Switch the hand±held tester from the normal mode
to the check mode. The CHK ENG blinks in 0.13 sec
intervals as shown in the illustration.
NOTICE:
If the hand±held tester switches the ECM from the normal
mode to the check mode or vice±versa, or if the ignition
switch is turned from ON to ACC or OFF during the check
mode, the DTC and freeze frame data will be erased.
(6) Start the engine. (The CHK ENG goes off after the
engine start.)
(7) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTC, etc.
(8) After simulating the malfunction conditions, use the
hand±held tester diagnosis selector to check the
DTCs and freeze frame data, etc.
HINT:
Be sure not to turn the ignition switch OFF, because the diagno-
sis system is changed from the check mode to the normal mode
and will result in all of the DTCs and freeze frame data being
erased.
(9) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clearing the DTCs using the hand±held tester:
(1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) When operating the hand±held tester to erase the
codes, the DTCs and freeze frame data will be
erased. (See the hand±held tester's instruction
book for operating instructions.)
