AVENSIS REPAIR MANUAL (RM1018E)
(c)Inspect the battery voltage. Battery voltage: 11 to 14 V
If voltage is below 11V, recharge the battery before proceeding.
(d)Check the CHK ENG.
(1)The CHK ENG lamp comes on when the ignitionswitch is turned ON and the engine is not running.
HINT:
If the CHK ENG is not illuminate, troubleshoot the combination
meter.
(2)When the engine is started, the CHK ENG shouldgo off. If the lamp remains on, it means that the diag-
nosis system has detected a malfunction or ab-
normality in the system.
2.DTC CHECK (Normal Mode):
NOTICE:
Hand±held tester only:
When the diagnosis system is switched from the normal
mode to the check mode, it erases all DTCs and freeze
frame data recorded in the normal mode. So before switch-
ing modes, always check the DTCs and freeze frame data,
and then write them down.
(a)Checking DTCs using the hand±held tester. (1)Connect the hand±held tester to the DLC3.
(2)Turn the ignition switch ON and switch the hand±held tester main switch ON.
(3)Use the hand±held tester to check the DTCs and freeze frame data and then write them down. If you
need help with the hand±held tester, refer to the
hand±held tester's instruction book).
(4)See page 05±544 to confirm the details of the
DTCs.
(b) Clearing the DTCs using the hand±held tester: (1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) When operating the hand±held tester to erase thecodes, the DTCs and freeze frame data will be
erased. (See the hand±held tester's instruction
book for operating instructions.)
(c) Clearing the DTCs not using the hand±held tester:
(1) Disconnect the battery terminal or remove the EFIand ETCS fuses from the engine room R/B for more
than 60 seconds.

3. DTC CHECK (Check Mode):
HINT:
Hand±held tester only:
Compared to the normal mode, the check mode has more sens-
ing ability to detect malfunctions. Furthermore, the same diag-
nostic items which are detected in the normal mode can also be
detected in the check mode.
(a) Procedure for Check Mode using the hand±held tester.
(1) Check the initial conditions.

Battery positive voltage 11V or more.

Throttle valve fully closed.

Transmission in the ºNº position.

A/C switched OFF.
(2) Turn the ignition switch OFF.
(3) Connect the hand±held tester to the DLC3.
(4) Turn the ignition switch ON and switch the hand±
held tester main switch ON.
(5) Switch the hand±held tester from the normal mode
to the check mode. The CHK ENG blinks in 0.13 sec
intervals as shown in the illustration.
NOTICE:
If the hand±held tester switches the ECM from the normal
mode to the check mode or vice±versa, or if the ignition
switch is turned from ON to ACC or OFF during the check
mode, the DTC and freeze frame data will be erased.
(6) Start the engine. (The CHK ENG goes off after the
engine start.)
(7) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTC, etc.
(8) After simulating the malfunction conditions, use the
hand±held tester diagnosis selector to check the
DTCs and freeze frame data, etc.
HINT:
Be sure not to turn the ignition switch OFF, because the diagno-
sis system is changed from the check mode to the normal mode
and will result in all of the DTCs and freeze frame data being
erased.
(9) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clearing the DTCs using the hand±held tester:
(1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) When operating the hand±held tester to erase the
codes, the DTCs and freeze frame data will be
erased. (See the hand±held tester's instruction
book for operating instructions.)

5. CHECK FOR INTERMITTENT PROBLEMS
Hand±held tester only:
By putting the vehicle's ECM in the check mode, the 1 trip detection logic is possible instead of the 2 trip
detection logic, and the sensitivity to detect faults is increased. This makes it easier to detect intermittent
problems.
(a) Clear the DTCs (See step 2).
(b) Set the check mode (See step 3).

(c)Perform a simulation test (See page 01±22).
(d)Check the connector and terminal (See page 01±32).
(e)Wiggle the harness and 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
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 its value differs from those listed here. Do not solely depend \
on the ºNormal Conditionº
here when deciding whether a part is faulty or not.
(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 LISTº.
(g) According to the display on tester, read the ºDATA LISTº.
