DIAGNOSIS SYSTEM
1. DESCRIPTION for EURO −OBD (European spec.)
S When troubleshooting Euro −OBD vehicles, the only dif-
ference from the usual troubleshooting procedure is that
you c onnect an O BD scan t ool com plying wit h I SO
1 503 1− 4 or a hand −held tester to the vehicle, and read
the various data output from the vehicle’s ECM.
S Eur o −O BD r egulat ions r equir e t hat t he v ehicle’s on −
board computer illuminates the check engine warning
light (CHK ENG (MIL)) on the instrument panel when the
computer detects a malfunction in: 1) the emission control
system / components, or 2) the powertrain control compo-
nents (which affect vehicle emissions), or 3) the comput-
er. In addition, the applicable Diagnostic Trouble Codes
(DTCs) prescribed by ISO 1503 1− 4 are recorded in the
ECM memory (see page 05 −564).
If the malfunction does not reoccur in 3 consecutive trips, the
CHK ENG (MIL) goes off automatically but the DTCs remain re-
corded in the ECM memory.
S To check the DTCs, connect the OBD scan tool or hand −
held tester to Data Link Connector 3 (DLC3) on the ve-
hicle. The OBD scan tool or hand −held tester also en-
ables you to erase the DTCs and check the freeze frame
data and various forms of engine data. (See the instruc-
tion manual for the OBD scan tool or the hand −held tes-
ter).
S DTCs include ISO controlled codes and manufacturer
controlled codes. ISO controlled codes must be set ac-
cording to the ISO, while manufacturer controlled codes
can be set by a manufacturer within certain restrictions
(see the DTC chart on page 05 −564).
S The diagnosis system operates in normal mode during
normal vehicle use. In ”normal mode”, 2 trip detection log-
ic* is used to ensure accurate detection of malfunctions.
A ”check mode”, is also available to technicians as an op-
tion. In ”check mode”, 1 trip detection logic is used for sim-
ulating malfunction symptoms and increasing the sys-
tem’s ability to detect malfunctions, including intermittent
malfunctions (hand −held tester only)
(see page 05 −557).
S*2 trip detection logic:
When a malfunction is first detected, the malfunction is
temporarily stored in the ECM memory ( 1st trip). If the
ignition switch is turned OFF and then ON again, and the
same malfunction is detected again, the CHK ENG (MIL)
will illuminate (2nd trip).

S Freeze frame data:
The freeze frame data records the engine conditions (fuel
system, calculated load, engine coolant temperature, fuel
trim, engine speed, vehicle speed, etc.) when a malfunc-
tion is detected. When troubleshooting, freeze frame data
can help determine if the vehicle was running or stopped,
if the engine was warmed up or not, if the air −fuel ratio
was lean or rich, and other data from the time the malfunc-
tion occurred.
2. DESCRIPTION for M −OBD (Except European spec.)
S When troubleshoot Multiplex OBD (M −OBD) vehicles, the
only difference from the usual troubleshooting procedure
is that you connect the hand −held tester to the vehicle,
and read the various data output from the vehicle’s ECM.
S The vehicle’s on −board computer illuminates the check
engine warning lamp (CHK ENG (MIL)) on the instrument
panel when the computer detects a malfunction in the
computer itself or in drive system components. In addi-
tion, the applicable Diagnostic Trouble Codes (DTCs) are
recorded in the ECM memory (see page 05 −564).
If the malfunction does not recur, the CHK ENG (MIL) goes off
be disappeared by turning the ignition switch to OFF, but the re-
corded DTCs remain in the ECM memory.
S To check the DTCs, connect the hand −held tester to the
Data Link Connector 3 (DLC3) on the vehicle or connect
terminals TC and CG on the DLC3(DTCs will be displayd
on the multi −information display).
S The diagnosis system operates in normal mode during
normal vehicle use. In ”normal mode”, 2 trip detection log-
ic* is used to ensure accurate detection of malfunctions.
A ”check mode”, is also available to technicians as an op-
tion. In ”check mode”, 1 trip detection logic is used for sim-
ulating malfunction symptoms and increasing the sys-
tem’s ability to detect malfunctions, including intermittent
malfunctions (hand −held tester only)
(see page 05 −558).
S*2 trip detection logic:
When a malfunction is first detected, the malfunction is
temporarily stored in the ECM memory ( 1st trip). If the
ignition switch is turned OFF and then ON again, and the
same malfunction is detected again, the CHK ENG (MIL)
will illuminate (2nd trip).

AVENSIS Supplement (RM1045E)
REPLACEMENT
NOTICE:
If an incorrect injector compensation code was registered with the ECM, it may rattle the engine as-
sembly or the engine idling may become rough. In addition, it may become a cause of engine failure
or shorten the life of the engine.
HINT:
SIn order to optimize the injector’s fuel injection characteristic, the ECM compensates the injection dura-
tion by each cylinder. The ECM stores and uses compensating data in the form of a 30−digit−alphanu-
meric value that is imprinted on the head portion of each injector as the injector compensation code.
SIf you installed a new injector, its own injector compensation code is needed to register with the ECM.
Also, if you replaced the ECM, the compensation codes of all the injectors are needed to register be-
cause the new ECM does not have the codes until they are registered.
SOnce the ECM is replaced, DTC P1601 will be present when turning the ignition switch to ON. This
is to inform you that the injector compensation codes are required to register with the ECM. In order
to clear the DTC, register the compensation codes first, then turn the ignition switch to OFF and wait
for 30 seconds or longer.
