± DIAGNOSTICSSFI SYSTEM (1ZZ±FE/3ZZ±FE)
AVENSIS REPAIR MANUAL (RM1018E)
ing fault code is 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) (However, the igni-
tion switch must be turned OFF between the 1st trip
and 2nd trip).

Freeze frame data:
Freeze frame data records the engine condition
when a misfire (DTCs P0300 ± P0304) or fuel trim
malfunction (DTCs P0171) or other malfunction
(first malfunction only), is detected.
Because freeze frame data records the engine
conditions (fuel system, calculated load, engine
coolant temperature, fuel trim, engine speed, ve-
hicle speed, etc.) when the malfunction is detected,
when troubleshooting it is useful for determining
whether the vehicle was running or stopped, the en-
gine warmed up or not, the air±fuel ratio lean or rich,
etc. at the time of the malfunction.

Priorities for troubleshooting:
If troubleshooting priorities for multiple DTCs are
given in the applicable DTC chart, these should be
followed.
If no instructions are given, troubleshoot according to the fol-
lowing priorities.
(1) DTCs other than fuel trim malfunction (DTCs
P0171) and misfire (DTCs P0300 ± P0304).
(2) Fuel trim malfunction (DTCs P0171).
(3) Misfire (DTCs P0300 ± P0304).
(b) Description for M±OBD (Except European spec.)

When troubleshoot Multiplex OBD (M±OBD) ve-
hicles, the only difference from the usual trouble-
shooting procedure is that you connect the hand±
held tester to the vehicle, and read the various data
output from the vehicle's ECM.

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.
(c) Check the DLC3.
The vehicle's ECM uses the ISO 9141±2 (Euro±OBD)/
ISO 14230(M±OBD) communication protocol. The termi-
nal arrangement of DLC3 complies with ISO 15031±03
and matches the ISO 9141±2/ ISO 14230 format.

4Chassis Ground ± Body Ground / 1

16Battery Positive ± Body Ground / 9 to 14 VAlways
HINT:
If the display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of the hand±held tester to
the DLC3, turned the ignition switch ON and operated the
hand±held tester, there is a problem on the vehicle side or tool
side.

If communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.

If communication is still not possible is when the tool is
connected to another vehicle, the problem is probably in
the tool itself, so consult the Service Deparment listed in
the tool's instruction manual.
(d) Inspect the battery voltage.
Battery voltage: 11 to 14 V
If voltage is below 11V, recharge the battery before proceeding.
(e) Check the CHK ENG.
(1) The CHK ENG lamp comes on when the ignition
switch is turned ON and the engine is not running.
HINT:
If the CHK ENG lamp is not illuminated, troubleshoot the com-
bination meter.
(2) When the engine is started, the CHK ENG should
go off. If the lamp remains on, it means that the diag-
nosis system has detected a malfunction or ab-
normality in the system.

5.CHECK FOR INTERMITTENT PROBLEMS
Hand±held tester only:
By putting the vehicle's engine ECM in check (test) mode, 1 trip detection logic is possible instead of 2 trip
detection logic, and sensitivity to detect faults is increased. This makes it eas\
ier to detect intermittent prob-
lems.
(a)Clear the DTC. (See step 3.)
(b)Set the check (test) mode. (See step 3.)
(c)Perform a simulation test. (See page 01±32)
(d)Check the connector and terminal. (See page 01±32)
(e)Wiggle the harness and the connector. (See page 01±32)
6. DATA LIST
HINT:
Using the DATA LIST displayed by the hand±held tester, you can read the value of the switches, sensors,
actuators and so on without parts removal. Reading the DATA LIST as a first step of troubleshooting is one
of the method to shorten diagnostic time.
NOTICE:
The values given below for ºNormal Conditionº are representative valu\
es. A vehicle may still be nor-
mal even if the measured values are a little different from those listed here. Do\
not decide whether
a part is faulty or not solely according to the ºNormal Conditionº\
here.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the Hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand±held tester.
(f) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALLº.
(g) According to the display on tester, read the ºDATA LISTº.
