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

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.

(2)Euro±OBD regulations require that the vehicle's on±board computer illuminates the Check Engine
Warning Light (Malfunction Indicator Lamp)/CHK
ENG (MIL) on the instrument panel when the com-
puter detects a malfunction in the emission control
system/components or in the driving system com-
ponents which affect vehicle emissions, or a mal-
function in the computer. In addition to CHK ENG
(MIL) illuminating when a malfunction is detected,
the applicable Diagnostic Trouble Codes (DTCs)
prescribed by ISO15031±6 are recorded in the
ECM memory.
If the malfunction does not occur in 3±trip, the CHK ENG (MIL)
goes off but the DTCs remain recorded in the ECM memory. (3)To check the DTCs, connect the OBD scan tool orhand±held tester to the Data Link Connector 3

tion code is temporarily 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 (MIL) to illumenate (2nd trip)
(However, the ignition switch must be turned OFF
between the 1st trip and the 2nd trip.).
(b) Description M±OBD
(1) When troubleshooting Multiplex (M±OBD) vehicles,
the only difference from the usual troubleshooting
procedure is that you connect the hand±held tester
to the vehicle, and read off various data output from
the vehicle's ECM.
(2) The vehicle's on±board computer illuminates the
MIL on the instrument panel when the computer de-
tects a malfunction in the computer itself or in driv-
ing system components. In addition to the MIL illu-
minating when a malfunction is detected, the
applicable DTCs are recorded in the ECM memory.
If the malfunction does not occur in 3±trip, the CHK ENG (MIL)
goes off but the DTCs remain recorded in the ECM memory.
(3) To check the DTCs, connect the hand±held tester
to DLC3 on the vehicle or read the number of blinks
of the MIL when TC and CG terminals on the DLC3
are connected. The hand±held tester also enables
you to erase the DTCs and activate the several ac-
tuators and check freeze frame data and various
forms of engine data (For instruction book).
(4) The diagnosis system operates in normal mode
during normal vehicle use, and also has a check
(test) mode for technicians to simulate malfunction
symptoms and perform troubleshooting. Most
DTCs use 2±trip detection logic (*) to prevent erro-
neous detection and ensure thorough malfunction
detection. By switching the ECM to check (test)
mode using the hand±held tester when trouble-
shooting, the technician can cause the MIL to illumi-
nate for a malfunction that is only detected once or
momentarily.
*2±trip detection logic:

function is temporarily stored in the ECM memory.

2nd test drive, this 2nd detection causes the MIL to
illuminate.
