cified and recommended. If using non–specified or recommended tools and service method,
be sure to confirm safety of the technicians and any possibility of causing personal injury or
damage to the customer’s vehicle before starting the operation.

If part replacement is necessary, must replace the part with the same part number or equivalent
part. Do not replace it with inferior quality.

It is important to note that this manual contains various ”Cautions” and ”Notices” that must be
carefully observed in order to reduce the risk of personal injury during service or repair, or the
possibility that improper service or repair may damage the vehicle or render it unsafe. It is also

(h) Carefully observe all specifications for bolt tightening
torques. Always use a torque wrench.
(i) Use of special service tools (SST) and special service ma-
terials (SSM) may be required, depending on the nature
of the repair. Be sure to use SST and SSM where speci-
fied and follow the proper work procedure. A list of SST
and SSM can be found in Preparation section in this
manual.
(j) When replacing fuses, be sure the new fuse has the cor-
rect amperage rating. DO NOT exceed the rating or use
one with a lower rating.
(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN–7).
(1) If the vehicle is to be jacked up only at the front or
rear end, make sure to place the stopper under the
wheels at the opposite end to block them in order to
ensure safety.

FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER
(a) The AVENSIS/ CORONA is equipped with an SRS (Sup-
plemental Restraint System), such as the driver airbag,
front passenger airbag, side airbags, curtain shield airbag
and seat belt pretensioners.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.
(b) GENERAL NOTICE
(1) Malfunction symptoms of the supplemental re-
straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting. When
troubleshooting the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the battery (See Pub. No. RM599E,
page DI–152).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the ”LOCK” posi-
tion and the negative (–) terminal cable is discon-
nected from the battery.
(The supplemental restraint system is equipped
with a back–up power source so that if work is
started within 90 seconds of disconnecting the neg-
ative (–) terminal cable from the battery, the SRS
may deploy.)
When the negative (–) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled. So before starting
work, make a record of the contents memorized by
the each memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory sys-
tem, never use a back–up power supply from out-
side the vehicle.

HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
GENERAL INFORMATION
A large number of ECU controlled systems are used in the AVENSIS/CORONA. In general, the ECU con-
trolled system is considered to be a very intricate system requiring a high level of technical knowledge and
expert skill to troubleshoot. However, the fact is that if you proceed to inspect the circuits one by one, trouble-
shooting of these systems is not complex. If you have adequate understanding of the system and a basic
knowledge of electricity, accurate diagnosis and necessary repair can be performed to locate and fix the
problem. This manual is designed through emphasis of the above standpoint to help service technicians
perform accurate and effective troubleshooting, and is compiled for the following major ECU controlled sys-
tems:
The troubleshooting procedure and how to make use of it are described on the following pages.

Supplemental Restraint SystemDI–1
FOR USING HAND–HELD TESTER
Before using the hand–held tester, the hand–held tester’s operator manual should be read thoroughly.
If the hand–held tester cannot communicate with ECU controlled systems when you have connected
the cable of the hand–held tester to DLC3, turned the ignition switch ON and operated the scan tool,
there is a problem on the vehicle side or tool side.
(1) If communication is normal when the tool is connected to another vehicle, inspect the diagnosis
data link line (Busline) or ECU power circuit of the vehicle.
(2) If communication is still not possible when the tool is connected to another vehicle, the problem
is probably in the tool itself, so perform the Self Test procedures outline in the Tester Operator’s
Manual.
