CUSTOMER PROBLEM ANALYSIS
HINT:
In troubleshooting, the problem symptoms must be confirmed accurately, meaning that all preconcep-
tions must be set aside in order to make an accurate judgement. To ascertain what the problem symp-
toms are, it is extremely important to ask the customer about the problem and conditions when it oc-
curred.
The following 5 items are important points in the problem analysis. Past problems which are thought
to be unrelated and the repair history, etc. may also help in some cases. Therefore, as much informa-
tion as possible should be gathered and its relationship with the problem symptoms should be correctly
ascertained for use as reference in troubleshooting. A customer problem analysis table is provided for
your use in the Diagnostics Section for each system.

HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
GENERAL INFORMATION
There are many ECU controlled systems used in the AVENSIS. In general, ECU controlled system are con-
sidered to be very intricate and require a high level of technical knowledge an\
d expert skill to troubleshoot.
The fact is, however, that if you proceed by inspecting the circuits one by one, troubleshoo\
ting of these sys-
tems is not complex. If you have adequate understanding of the system and ba\
sic knowledge of electricity,
the problem can be accurately diagnosed and fixed. This manual is design\
ed based on the above principle
to help service technicians perform accurate and effective troubleshooting, and is compiled for the following
major ECU controlled systems:
The troubleshooting procedures are described on the following pages.

FOR USING HAND±HELD TESTER

Before using the tester, the tester's operator manual should be read thoroughly.

If the tester cannot communicate with the ECU controlled systems when you \
have connected the cable
of tester to the DLC3, turned the ignition switch ON and operated the test\
er, there is a problem on the
vehicle side or tester side.
(1) If the communication is normal when the tester is connected to another veh\
icle, inspect the diag-
nosis data link line (Bus
line) or ECU power circuit of the vehicle.
(2) If the communication is still impossible when the tester is connected to a\
nother vehicle, the prob- lem is probably in the tester itself, so perform the Self Test procedures outlined in the Tester Oper-
ator 's Manual.

INTRODUCTION REPAIR INSTRUCTION
AVENSIS REPAIR MANUAL (RM1018E)
(3)Even in the case of a minor collision where the SRS does not deploy, the horn button assembly, instrument panel passenger airbag assembly and seat belt pretensioner should be in\
spected
(See pages 60±19, 60±19 and 61±9).
(4)Never use the SRS related parts from another vehicle. When replacing the part\
s, replace them with new parts.
(5)Before repairs, remove the airbag sensor if there is a possibility of sh\
ock during repairs.
(6)Never disassemble and repair the center airbag sensor assembly, side airbag sensor assembly, horn button assembly, instrument panel passenger airbag assembly, front seat airbag assembly,
curtain shield airbag assembly or seat belt pretensioner.
(7)If the center airbag sensor assembly, the side airbag sensor assembly, the horn button assembly, the instrument panel passenger airbag assembly have been dropped, or if the\
re are cracks,
dents or other defects in the case, bracket or connector, replace them with new ones.
(8)Do not directly expose the airbag sensor assembly, the side airbag sensor assembly, the horn button assembly, the instrument panel passenger airbag assembly or the seat belt pretensioner
to hot air or flames.
(9)Use a volt/ohmmeter with high impedance (10 k
/V minimum) for troubleshooting electrical cir-
cuits.
(10)Information labels are attached to the SRS components. Follow the instru\
ctions on the notices.
(11)After work on the supplemental restraint system is completed, check the SRS w\
arning light (See page 05±1184)
(b)SPIRAL CABLE (in Combination Switch)(1)The steering wheel must be fitted correctly to thesteering column with the spiral cable at the neutral
position, otherwise cable disconnection and other
troubles may occur. Refer to page 60±26 of this
manual concerning the correct installation of the
steering wheel.
(c) HORN BUTTON ASSEMBLY (with Airbag) (1) When removing the horn button assembly or handling a new horn button, it sho\
uld be placed withthe top of the pad surface facing upward. Placing it with the pad surface facing downward may
lead to a serious accident if the airbag deploys for some reasons. Also, do \
not place anything
on top of the horn button.
(2) Never measure the resistance of the airbag squib (This may cause the airbag to inflate, which is very dangerous).
(3) Grease should not be applied to the horn button assembly, and the pad should not be cleaned with any type of detergent.
(4) Store the horn button assembly where the ambient temperature remains below 93
C (200
F),
without high humidity and away from electrical noise.
(5) When using electric welding, disconnect the airbag connector (4 yellow pins\
) under the steering column near the combination switch connector before starting work.
