PRE±CHECK
1.DIAGNOSIS SYSTEM
(a)Description for Euro±OBD (European spec.)

When troubleshooting Euro±OBD vehicles, the
only difference from the usual troubleshooting pro-
cedure is that you connect an OBD scan tool com-
plying with ISO 15031±4 or a hand±held tester to
the vehicle, and read off various data output from
the vehicle's ECM.

Euro±OBD regulations require that the vehicle's
on±board computer illuminates the check engine
warning light (CHK ENG) on the instrument panel
when the computer detects a malfunction in the
emission control system / components or in the
powertrain control components which affect ve-
hicle emissions, or a malfunction in the computer. In
addition to an illumination of the CHK ENG when a
malfunction is detected, the applicable Diagnostic
Trouble Codes (DTCs) prescribed by ISO 15031±4
are recorded in the ECM memory (See page
05±309). If the malfunction does not reoccur in 3
consecutive trips, the CHK ENG goes off automati-
cally but the DTCs remain recorded in the ECM
memory.

To check the DTCs, connect the OBD scan tool or
hand±held tester to Data Link Connector 3 (DLC3)
on the vehicle. The OBD scan tool or hand±held
tester also enables you to erase the DTCs and
check freeze frame data and various forms of en-
gine data. (For operating instructions, see the OBD
scan tool's instruction book.)
DTCs include ISO controlled codes and manufac-
turer controlled codes. ISO controlled codes must
be set as prescribed by the ISO, while manufacturer
controlled codes can be set freely by the manufac-
turer within the prescribed limits (See DTC chart on
page 05±309).

The diagnosis system operates in the normal mode
during normal vehicle use. It also has a check (test)
mode for technicians to simulate malfunction symp-
toms and troubleshoot. Most DTCs use 2 trip detec-
tion logic* to prevent erroneous detection, and to
ensure a thorough malfunction detection. By
switching the ECM to the check (test) mode using
hand±held tester when troubleshooting, a techni-
cian can cause the CHK ENG to illuminate for a mal-
function that is only detected once or momentarily
(Hand±held tester only) (See step 3).

DIAGNOSTICS SFI SYSTEM(1AZ±FSE)
AVENSIS REPAIR MANUAL (RM1018E)

The vehicle's on±board computer illuminates the
check engine warning light (CHK ENG) on the
instrument panel when the computer detects a mal-
function in the computer itself or in drive system
components. In addition to an illumination of the
CHK ENG when a malfunction is detected, the ap-
plicable Diagnostic Trouble Codes (DTCs) are re-
corded in the ECM memory (See page 05±309). If
the malfunction does not recur, the CHK ENG lamp
will be disappeared by turning off the ignition switch
but the recorded DTC will be remaining in the ECM
memory.

To check the DTCs, connect the hand±held tester
to the Data Link Connector 3 (DLC3) on the vehicle.
The hand±held tester also enables you to erase the
DTCs and check the freeze frame data and various
forms of engine data. (for operating instructions,
see the instruction book.)

The diagnosis system operates in the normal mode
during normal vehicle use. It also has a check (test)
mode for technicians to simulate malfunction symp-
toms and troubleshoot. Most DTCs use 2 trip detec-
tion logic* to prevent erroneous detection, and to
ensure a thorough malfunction detection. By
switching the ECM to the check (test) mode using
hand±held tester when troubleshooting, a techni-
cian can cause the CHK ENG to illuminate for a mal-
function that is only detected once or momentarily
(Hand±held tester only) (See step 3).

* 2 trip detection logic
When a logic malfunction is first detected, the mal-
function is temporally 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) (How-
ever, the ignition switch must be turned OFF be-
tween the 1st trip and 2nd trip).

Freeze frame data:
Freeze frame data records the engine conditions
(fuel system, calculator load, water temperature,
fuel trim, engine speed, vehicle speed, etc.) when
a malfunction is detected. When troubleshooting, it
is useful for determining whether the vehicle was
running or stopped, the engine was warmed up or
not, the air±fuel ratio was lean or rich, etc. at the
time of the malfunction.

(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.

(5) Switch the hand±held tester from the normal mode
to the check (test) 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.)
(c) Clearing the DTCs not using the hand±held tester.
(1) Disconnect the battery terminal or remove the EFI
and THROTTLE fuses from the engine room R/B
No. 1 for more than 60 seconds.
