PROBLEM SYMPTOMS TABLE
The suspected circuits or parts for each problem symptom are shown in the t\
able below. Use this table to
troubleshoot the problem when a Normal code is displayed in the diagnostic trouble c\
ode chart but the prob-
lem is still occurring. Numbers in the table indicate the order in which\
the circuits or parts should be checked.
HINT:
When the problem is not detected by the diagnostic system even though the pr\
oblem symptom is present,
it may be that the problem is occurring outside the detection range of t\
he diagnostic system.
Symptom Suspected AreaSee page

6. HANDLING OF HOSE CLAMPS
(a) Before removing the hose, check the depth of the insert-
ing portion and the clamp position to restore it surely.
(b) Change a deformed or dented clamp for a new one.
(c) In case of reusing a hose, attach the clamp on the clamp
track portion of the hose.
(d) For a spring type clamp, adjust it by adding force to the
arrow mark direction after the installation.
7. FOR VEHICLES EQUIPPED WITH MOBILE COMMU-
NICATION SYSTEMS
(a) Install the antenna as far away from the ECU and sensors
of the vehicle electronic systems as possible.
(b) Install an antenna feeder at least 20 cm (7.87 in.) away
from the ECU and sensors of the vehicle electronic sys-
tems. For details of the ECU and sensors locations, refer
to the section on applicable components.
(c) Prevent the antenna feeder from getting entangled with
the other wiring, and keep the antenna feeder separate
from other wiring as much as possible.
(d) Check that the antenna and feeder are correctly adjusted.
(e) Do not install any high±powered mobile communication
system.
8. FOR VEHICLES EQUIPPED WITH TRACTION CONTROL (TRC) SYSTEM
(a) NOTICES WHEN USING 2±WHEEL DRUM TESTER
(1) When using a 2±wheel drum tester such as a speedometer tester, a combination tester of
speedometer and brake, chassis dynamometer or else, always turn the TRC system off via the
TRC OFF switch before measurement.
NOTICE:
TRC system OFF condition can be confirmed by the indication, ºTRC OFFº, of the warning light in
the combination meter.
9. FOR VEHICLES EQUIPPED WITH VEHICLE SKID
CONTROL (VSC) SYSTEM
(a) NOTICES WHEN USING DRUM TESTER
(1) When using a drum tester, be sure to start the en-
gine with the ignition OFF, and connect SST to the
terminals TS and CG of the DLC3 before measure-
ment in order to prohibit the VSC operation.

AVENSIS REPAIR MANUAL (RM1018E)
NOTICE:

Confirm that the VSC warning light blinks.

VSC system will be reset when the engine is re-
started.

Fasten the vehicle with lock chains.
(b) NOTICES OF RELATED OPERATIONS TO VSC
(1) Do not carry out unnecessary installation and re-
moval as it might disorder the adjustment of related
parts to VSC.
(2) Be sure to carry out the preparation for operation
and the confirmation of operation completion in ac-
cordance with the instruction of the text and when
the related operations to VSC are performed.
10. FOR VEHICLES EQUIPPED WITH CATALYTIC CONVERTER
CAUTION:
If a large amount of unburned gasoline flows into the converter, it may cause overheating and is a
fire hazard. To prevent this, observe the following precautions.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid idling the engine for more than 20 minutes.
(c) Avoid a spark jump test.
(1) Perform a spark jump test only when absolutely necessary. Perform this test as rapidly as pos-
sible.
(2) While testing, never race the engine.
(d) Avoid a prolonged engine compression measurement.
Engine compression measurements must be performed as rapidly as possible.
(e) Do not run the engine when the fuel tank is nearly empty. This may cause the engine to misfire and
create an extra load on the converter.
