REPAIR INSTRUCTIONS
GENERAL INFORMATION
BASIC REPAIR HINT
(a) Use fender, seat and floor covers to keep the vehicle
clean and prevent damage.
(b) During disassembly, keep parts in the appropriate order
to facilitate reassembly.
(c) Installation and removal of battery terminal:
(1) Before performing electrical work, disconnect the
negative (–) terminal cable from the battery.
(2) If it is necessary to disconnect the battery for in-
spection or repair, first disconnect the negative (–)
terminal.
(3) When disconnecting the terminal cable, to prevent
damage to the battery terminal, loosen the cable
nut and raise the cable straight up without twisting
or prying it.
(4) Clean the battery terminals and cable ends with a
clean shop rag. Do not scrape them with a file or oth-
er abrasive objects.
(5) Install the cable ends to the battery terminals after
loosening the nut and tighten the nut after installa-
tion. Do not use a hammer to tap the cable ends
onto the terminals.
(6) Be sure the cover for the positive (+) terminal is
properly in place.
(d) Check hose and wiring connectors to make sure that they
are connected securely and correctly.
(e) Non–reusable parts
(1) Always replace cotter pins, gaskets, O–rings and oil
seals, etc. with new ones.
(2) Non–reusable parts are indicated in the component
illustrations by the ”
” symbol.
(f) Precoated parts
Precoated parts are bolts and nuts, etc. that are coated
with a seal lock adhesive at the factory.
(1) If a precoated part is retightened, loosened or
caused to move in any way, it must be recoated with
the specified adhesive.
(2) When reusing precoated parts, clean off the old
adhesive and dry with compressed air. Then apply
the specified seal lock adhesive to the bolt, nut or
threads.
(3) Precoated parts are indicated in the component il-
lustrations by the ”” symbol.
(g) When necessary, use a sealer on gaskets to prevent
leaks.

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.

(h) SEAT BELT PRETENSIONER
(1) Never measure the resistance of the seat belt pre-
tensioner. (This may cause the pretensioner oper-
ates, which is very dangerous.)
(2) Oil or water should not be put on the front seat outer
belt and the front seat outer belt should not be
cleaned with detergents of any kind.
(3) Store the front seat outer belt where the ambient
temperature remains below 80
C (176
F), without
high humidity and away from electrical noise.
(4) When using electric welding, first disconnect the
connector (yellow color and 2 pins) installed at the
center pillar lower garnish before starting work.
(5) When disposing of a vehicle or a front seat outer
belt alone, the seat belt pretensioner should be acti-
vated before disposal (See Pub. No. RM599E,
page BO–153). Perform the operation in a safe
place away from electrical noise.
(i) AIRBAG SENSOR ASSEMBLY
(1) Never reuse the airbag sensor assembly involved
in a collision when the SRS has deployed.
(2) The connectors to the airbag sensor assembly
should be connected or disconnected with the sen-
sor mounted on the floor. If the connectors are con-
nected or disconnected while the airbag sensor as-
sembly is not mounted to the floor, it could cause
undesired ignition of the supplemental restraint sys-
tem.
(3) 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, even if only loosing the set
bolts of the airbag sensor assembly.
(j) WIRE HARNESS AND CONNECTOR
The SRS wire harness is integrated with the instrument
panel wire harness and the cowl wire harness assembly
and floor wire harness assembly. The wires for the SRS
wire harness are encased in a yellow corrugated tube. All
the connectors for the system are also a standard yellow
color. If the SRS wire harness becomes disconnected or
the connector becomes broken due to an accident, etc.,
repair or replace it as shown on Pub. No. RM599E, page
RS–65.

5. FOR VEHICLES EQUIPPED WITH POWER WINDOW CONTROL SYSTEM
When the battery is disconnected or the power to the window regulator motor is cut, the power window con-
trol system does not operate. It is necessary to initialize the system in the following procedures. Otherwise
window cannot be operated normally.
(1) Close window to the highest position.
(2) Keep holding the switch for 5 seconds.
(3) Check that automatic operation works. If not, repeat the above procedures.
6. FOR VEHICLES EQUIPPED WITH SLIDING ROOF SYSTEM
Sliding roof stop position might be required to be initialized when battery failures (such as battery disconnec-
tion, connector disconnection and the voltage drop) are detected while the system is in operation. This also
occurs when rotating the motor with the battery disconnected. Sliding roof initialization can be done by the
following procedures.
(1) Operate the roof up to the maximum tilt position.
(2) Release the switch, and push it again in the same direction. (After 10 seconds have elapsed,
initialization begins.)
(3) The roof starts automatic operation if holding the switch, completes full one cycle (tilt down, slide
open, slide close and tilt up) of travel. Do not release the switch until the roof stops.
(4) Check that the roof stops at the correct position.
7. FOR VEHICLES EQUIPPED WITH BRAKE PIPE FIT-
TING OF NEW STANDARD
A flare shape of a new standard is used for the brake pipe fitting
from this changed models.
NOTICE:
When ordering or replacing the parts, please be sure
to check and use the fitting of the same flare type.
Do not over–tighten them more than the standard
torque.
Torque: 15 N·m (155 kgf·cm, 11 ft·lbf)
