PRE±CHECK
1.DIAGNOSIS SYSTEM
(a)Description for Euro±OBD
(1)When troubleshooting Euro±OBD vehicles, theonly difference from the usual troubleshooting pro-
cedure is that you connect the vehicle to the OBD
scan tool complying with ISO 15031±4 or hand±
held tester, and read off various data output from
the vehicle's ECM.
(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
(DLC3) on the vehicle. The OBD scan tool or hand±
held tester also enables you to erase the DTCs and
check freezed frame data and various forms of en-
gine data (For operating instructions, see the OBD
scan tool's instruction book.).
(4)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±876).
(5) The diagnosis system operates in normal mode during normal vehicle use. It also has a check mode
for technicians to simulate malfunction symptoms
and troubleshoot. Most DTCs use 2 trip detection
logic (*) to prevent erroneous detection, and ensure
thorough malfunction detection. By switching the
ECM to check mode when troubleshooting, techni-
cians can cause the CHK ENG (MIL) to light up for
a malfunction that is only detected once or momen-
tarily (Hand±held tester only) (See step 2).

TRANSAXLE [ECT] (U241E(1AZ±FE))
AVENSIS REPAIR MANUAL (RM1018E)
(6) *2 trip detection logic:
When a malfunction is first detected, the malfunc-
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:
When a logic malfunction is first detected, the mal-
function is temporarily stored in the ECM memory.
If the same malfunction is detected again during the
2nd test drive, this 2nd detection causes the MIL to
illuminate.

(1)Use the hand±held tester to check the DTCs and instructions, see the hand±held tester instruction
book.
(2)See page 05±876 to confirm the details of the DTCs.
(c) Check the DTC (Not using the hand±held tester). (1) Turn the ignition switch ON, but do not start the en-
gine.
(2) Using SST, connect terminals 13 (TC) and 4 (CG) of DLC3.

(3) Read the DTC indicated by the number of times of the MIL blinks.
HINT:
If the system is operating normally, the light will blink 2 times per
second.
(4) The malfunction code is indicated, as shown in thechart on the left (DTC º42º is shown as an example).
HINT:
When 2 or more malfunction codes are stored in memory, the
lower±numbered code is displayed first.
