INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester II. Freeze frame data record the engine condition\
when
malfunctions are detected. When troubleshooting, freeze frame data can h\
elp determine if the vehicle was
moving or stationary, if the engine was warmed up or not, if the air–fuel ratio was lean \
or rich, and other data
from the time the malfunction occurred.
1 PERFORM ACTIVE TEST USING INTELLIGENT TESTER II(EVAP VSV)
(a) Disconnect the vacuum hose of the EVAP VSV.
(b) Connect the intelligent tester II to the DLC3.
(c) Start the engine and turn the intelligent tester II ON.
(d) Select the following menu items: Powertrain / Engine and ECT / Active Test / Purge VSV. Press the right or left but-
ton.
(e) Check if the disconnected port applies suction to your fin-
ger when operating the EVAP VSV using the intelligent
tester II.
Standard:

VSV is OFFApplies no suction to your finger
(f) Reconnect the vacuum hose.

HINT:
Intelligent tester II only:
Malfunctioning areas can be found by performing the Active Test / A/F Control operation. The A/F Control
operation can determine if the heated oxygen sensor or other potential trouble ar\
eas are malfunctioning or
not.
(a) Perform the Active Test using the intelligent tester II.
HINT:
The A/F Control operation lowers the injection volume by 12.5 % or incre\
ases the injection volume by 25
%. (1) Connect the intelligent tester II to the DLC3.
(2) Start the engine and turn the intelligent tester II ON.
(3) Warm up the engine by running the engine at 2,500 rpm for approximately 3\
minutes.
(4) On the intelligent tester II, select the following menu items: Powertrain \
/ Engine and ECT / ActiveTest / A/F Control.
(5) Select the following monitor items: O2S B1 S1 and O2S B1 S2.
(6) Perform the A/F Control operation with the engine in an idling condition\
(press the right or left
button).
Result:
The heated oxygen sensor reacts in accordance with increases and decreases \
of the injection
volume:
+25 % → Rich output: More than 0.5 V
–12.5 % → Lean output: Less than 0.4 V
NOTICE:

AVENSIS REPAIR MANUAL SUPPLEMENT
(RM1098E)
INSPECTION PROCEDURE
HINT:
If any DTCs other than the misfire DTCs are set simultaneously, first troubleshoot them.
If a misfire does not occur when the vehicle is brought to the workshop, a mi\
sfire can be confirmed by
reproducing the condition of the freeze frame data. Also, after finishing repairs, \
confirm that misfires
do not recur (see the confirmation driving pattern).
Read freeze frame data using the intelligent tester II. Freeze frame dat\
a record the engine condition
when malfunctions are detected. When troubleshooting, freeze frame data \
can help determine if the
vehicle was moving or stationary, if the engine was warmed up or not, if the air–fuel ratio was lean \
or
rich, and other data from the time the malfunction occurred.
On 6 and 8 cylinder engines, misfiring cylinders cannot be identified at\
high engine speed and only
a general misfire DTC P0300 is stored instead of the individual misfiring\
cylinder DTCs (P0301 to
P0308).
If a misfire starts in a high engine speed area or a misfire occurs only i\
n a high engine speed area, only
DTC P0300 may be stored.
When only a general misfire DTC P0300 is stored:
Erase the general misfire DTC from the ECM using the intelligent tester \
II.
Start the engine and perform the confirmation driving pattern.
Check the value of the misfire ratio for each cylinder. Or check the DTC(s).
Perform repairs on the cylinder that has a high misfire ratio. Or repair the cy\
linder indicated by the DTC.
After finishing repairs, perform the confirmation driving pattern again and c\
onfirm that no misfire oc-
curs.
When either of Short FT #1 and Long FT #1 in the freeze frame data is over the range of 20 %, there
is a possibility that the air–fuel ratio is becoming rich (–20 % \
or less) or lean (+20 % or more).
When Coolant Temp in the freeze frame data is less than 80
C (176
F), there is a possibility that mis-
fires occur only during engine warm–up.
If a misfire cannot be reproduced, the following reasons may apply: 1) th\
e vehicle has low fuel, 2) im-
proper fuel is being used, and 3) the ignition plug has been contaminated.
Be sure to check the misfire counter value after repairs.
1 CHECK OTHER DTC OUTPUT(IN ADDITION TO MISFIRE DTCS)
(a) Connect the intelligent tester II to the DLC3.
(b) Turn the ignition switch to ON and turn the intelligent tester ll ON.
(c) Select the following menu items: Powertrain / Engine and ECT / DTC.
(d) Read DTCs. Result:

or P0304 are output, troubleshoot those DTCs.
