AVENSIS REPAIR MANUAL (RM1018E)
SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE
HINT:
The diagnostic system in AVENSIS has various functions. The first function is the Diagnostic Trouble
Code (DTC) Check, in which a malfunction in the signal circuits to the ECU is stored in code form in
the ECU memory. Another function is the Input Signal Check, which checks if the signals from various
switches are sent to the ECU correctly. By using these check functions, it is possible to quickly narrow
down potential problem areas and troubleshooting can be performed effectively. The diagnostic func-
tions are incorporated in the following systems in the AVENSIS.

In the DTC check, it is very important to determine whether the problem indicated by the DTC is still
occurring or has occurred in the past but returned to normal at present. In addit\
ion during the problem
symptom check, it a check must be made on whether the malfunction indicated by \
the DTC is directly
related to the problem symptom or not. For this reason, the DTC should be checked before and after
symptom confirmation to determine the current conditions. If this is not done, \
it may, depending on the
case, result in unnecessary troubleshooting for systems that are operati\
ng normally. This would make
more difficult to detect the problem area or to try to repair irrelevant areas. \
Therefore, always follow
the procedures in the correct order and perform the DTC check.
A flow chart showing how to proceed with troubleshooting using the diagnostic trouble\
code (DTC)
check is shown the this page. This flow chart shows how to utilize the DTC check effectively. Then,
by carefully checking the results, this chart indicates how to proceed either to the DTC troubleshooting
or to the troubleshooting of the problem symptoms table.

3. INSPECT IDLE AIR CONTROL VALVE
NOTICE:
It is impossible to check the resister value and the op-
eration of ISCV by itself, because the ISCV has an IC
circuit inside it, which transforms the duty signal
from the ECM to the derive signal.
After checking, erase the DTC.
Clear the DTC after inspection.
HINT:
When the ISCV system has malfunctions except for its adher-
ence, DTC P0511 is detected.
(a) Operation inspection. (1) Connect the ISC valve connector to the ISC valve.
(2) Check the ISC valve movement when the ignitionswitch is turned ON.
Movement:
Half open fully close fully open half open
HINT:
ISC valve moves within 0.5 second.

Standard specific gravity: 1.25 to 1.29 at 20 C (68F)
4. INSPECT AIR CLEANER FILTER ELEMENT SUB±ASSY
5.INSPECT SPARK PLUG (See page 18±9)
6. INSPECT V±RIBBED BELT
7. INSPECT IGNITION TIMING
(a) Warm up engine.
(b) When using hand±held tester:(1) Connect the hand±held tester to the DLC3.
(2) Enter DATA LIST MODE on the hand±held tester.
Ignition timing: 8 to 12 BTDC
HINT:
Please refer to the hand±held tester operator's manual if you
need help to select DATA LIST.
(c) When not using hand±held tester:
(1) Using SST, connect terminals 13 (TC) and 4 (CG)of DLC3.
SST 09843±18040
NOTICE:
Make sure of the terminal numbers before connecting
them. Connection with a wrong terminal can damage
the engine.
Turn OFF all electrical systems before connecting the
terminals.
Operate the inspection after the cooling fan motor is
turned OFF.
(2) Remove the cylinder head cover No.2.
(3) Pull out the wire harness as shown in the illustration.
Connect the clip of the timing light to the engine.
NOTICE:
Use a timing light which detects the first signal.
After checking, be sure to wrap the wire harness with
tape.
(4) Inspect ignition timing at idle.
Ignition timing: 8 to 12 BTDC
NOTICE:
When checking the ignition timing, shift the transmission
to the neutral position.
HINT:
Run the engine at 1,000 to 1,300 rpm for 5 seconds, check that
the engine rpm returns to the idle speed.
