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).

PROBLEM SYMPTOMS TABLE
HINT:
If a normal code is displayed during the diagnostic trouble code check although the trouble still occurs, check
the electrical circuits for each symptom in the order given in the charts on the following pages and proceed
to the page given for troubleshooting.
The Matrix Chart is divided into 2 chapters.
1. Chapter 1: Electronic Circuit Matrix Chart
S Refer to the table below when the trouble cause is considered to be electrical.
S If the instruction ”Proceed to next circuit inspection shown on matrix chart” is given in the flow chart
of each circuit, proceed to the circuit with the next highest number in the table to continue the check.
S If the trouble still occurs even though there are no abnormalities in any of the other circuits, check and
replace the ECM.
HINT:

MONITOR DRIVE PATTERN
1. MONITOR DRIVE PATTERN FOR ECT TEST
(a) Perform this drive pattern as one method to simulate the detection conditions of the ECT malfunctions.
(The DTCs may not be detected due the actual driving conditions. And some codes may not be de-
tected through this drive pattern).
HINT:
Preparation for driving
SWarm up the engine sufficiently. (Engine coolant temperature is 60˚C(140˚F) or higher)
SDrive the vehicle when the atmospheric temperature is−10˚C(14˚F) or higher. (Malfunction is not
detected when the atmospheric temperature is−10˚C(14˚F) or less)
Driving note
SDrive the vehicle through all gears.
Stop

4th
5th
5th (lock−up ON).
SPerform engine brake test in the S position.
While driving in the 5(S) position and 5th gear lock−up, shift into the ”−” position and down−shift from
5th to 4th, 4th to 3rd, 3rd to 2nd, 2nd to1st.
Check that the engine brake performs properly whenever down−shift takes place.
SRepeat the above driving pattern three times or more.
NOTICE:
SWhen using the hand−held tester, monitor status can be found in the ”DIAGNOSIS / OBD/MOBD
/ DATA LIST”.
SIn the event that the drive pattern must be interrupted (possibly due to traffic conditions or other
factors) the drive pattern can be resumed and, in most cases, the monitor can be completed.
CAUTION:
Perform this drive pattern on a level road as much as possible and strictly observe the posted speed
limits and traffic laws while driving.

− FUELINJECTOR ASSY (1CD−FTV)(From September, 2003)
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.
1. REMOVE VACUUM RESERVOIR SUB−ASSY
(a) Disconnect the 2 vacuum hoses and connector.
(b) Remove the 2 bolts and vacuum reservoir.

maining inside the pipe.
16. REMOVE NOZZLE HOLDER CLAMP
(a) Remove the 4 bolts, 4 washers and 4 nozzle holder clamps.
17. REMOVE INJECTOR ASSY
HINT:
Each injector assembly has its own fuel injection characteristic. When replacing the injector assembly, store
them in the correct order so that they can be returned to the original locations when reassembling.
(a) Remove the 4 injectors from the cylinder head.
(b) Remove the O −rings and back −up rings from each injector.
(c) Remove the 4 nozzle seats from the cylinder head.
