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) Observe the following operations:
(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, always disconnect the negative
(−) terminal cable which is grounded to the vehicle
body.
(3) 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 with
the nut loose, and tighten the nut after installation.
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 secure and correct.
(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.

(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−8).
(1) If the vehicle is to be jacked up only at the front or
rear end, be sure to block the wheels at the opposite
end in order to ensure safety.
(2) After the vehicle is jacked up, be sure to support it
on stands. It is extremely dangerous to do any work
on a vehicle raised on a jack alone, even for a small
job that can be finished quickly.
(l) Observe the following precautions to avoid damage to the
following parts:
(1) Do not open the cover or case of the ECU, ECM,
PCM or TCM unless absolutely necessary. (If the IC
terminals are touched, the IC may be destroyed by
static electricity.)
(2) To disconnect vacuum hoses, pull off the end, not
the middle of the hose.
(3) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(4) Be careful not to drop electrical components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not reused.
(5) When steam cleaning an engine, protect the elec-
tronic components, air filter and emission−related
components from water.
(6) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(7) When checking continuity at the wire connector, in-
sert the tester probe carefully to prevent terminals
from bending.
(8) When using a vacuum gauge, never force the hose
onto a connector that is too large. Use a step−down
adapter for adjustment. Once the hose has been
stretched, it may leak.
(m) Tag hoses before disconnecting them:
(1) When disconnecting vacuum hoses, use tags to
identify how they should be reconnected to.
(2) After completing a job, double check that the vacu-
um hoses are properly connected. A label under the
hood shows the proper layout.

FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG
(a) The TOYOTA T100 is equipped with an SRS (Supple-
mental Restraint System), such as the driver airbag.
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 page DI−365).
(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.
(3) Even in cases of a minor collision where the SRS
does not deploy, the steering wheel pad should be
inspected (See page RS−9).

(4) Never use SRS parts from another vehicle. When
replacing parts, replace them with new parts.
(5) Before repairs, remove the center airbag sensor if
shocks are likely to be applied to the sensor during
repairs.
(6) Never disassemble and repair the center airbag
sensor assembly, steering wheel pad in order to re-
use it.
(7) If the center airbag sensor assembly, steering
wheel pad have been dropped, or if there are
cracks, dents or other defects in the case, bracket
or connector, replace them with new ones.
(8) Do not expose the center airbag sensor assembly,
steering wheel pad directly to hot air or flames.
(9) Use a volt/ohmmeter with high impedance (10 kΩ/V
minimum) for troubleshooting of the electrical cir-
cuit.
(10) Information labels are attached to the periphery of
the SRS components. Follow the instructions on the
notices.
(11) After work on the supplemental restraint system is
completed, check the SRS warning light (See page
DI−365).
(c) FRONT AIRBAG SENSOR
(1) Never reuse the front airbag sensors involved in a
collision that activated the supplemental restraint
system. (Replace both left and right airbag sen-
sors.)
(2) Install the front airbag sensor with the arrow on the
sensor facing toward the front of the vehicle.
The front airbag sensor set bolts have been anti−
rust treated. When the sensor is removed, always
replace the set bolts with new ones.
(3) The front airbag sensor is equipped with an electri-
cal connection check mechanism. Be sure to lock
this mechanism securely when connecting the con-
nector.
(4) If connector is not securely locked, a malfunction
code will be the diagnosis system (See page
RS−2).

(e) STEERING WHEEL PAD (with Airbag)
(1) When removing the steering wheel pad or handling
a new steering wheel pad, it should be placed with
the pad top surface facing up.
In this case, the twin−lock type connector lock lever
should be in the locked state and care should be
taken to place it so the connector will not be dam-
aged. In addition do not store a steering wheel pad
on top of another one. Storing the pad withits metal-
lic surface facing upward may lead to a serious acci-
dent if the airbag inflates for some reason.
(2) Never measure the resistance of the airbag squib.
(This may cause the airbag to deploy, which is very
dangerous.)
(3) Grease should not be applied to the steering wheel
pad and the pad should not be cleaned with deter-
gents of any kind.
(4) Store the steering wheel pad where the ambient
temperature remains below 93°C (200°F), without
high humidity and away from electrical noise.
(5) When using electric welding, first disconnect the air-
bag connector (yellow color and 2 pins) under the
steering column near the combination switch con-
nector before starting work.
(6) When disposing of a vehicle or the steering wheel
pad alone, the airbag should be deployed using an
SST before disposal (See page RS−11).
Carry out the operation in a safe place away from
electrical noise.

(f) CENTER AIRBAG SENSOR ASSEMBLY
(1) Never reuse the center airbag sensor assembly in-
volved in a collision when the SRS has deployed.
(2) The connectors to the center airbag sensor assem-
bly should be connected or disconnected with the
sensor mounted on the floor. If the connectors are
connected or disconnected while the center airbag
sensor assembly is not mounted to the floor, it could
cause undesired ignition of the supplemental re-
straint system.
(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 loosening the
set bolts of the center airbag sensor assembly.
(g) WIRE HARNESS AND CONNECTOR
The SRS wire harness is integrated with the cowl wire har-
ness 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 be-
comes disconnected or the connector becomes broken
due to an accident, etc., repair or replace it.
2. FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION:
If large amount of unburned gasoline flows into the converter, it may overheat and create a fire haz-
ard. To prevent this, observe the following precautions and explain them to your customer.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.
(c) Avoid spark jump test.
(1) Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine.
(d) Avoid prolonged engine compression measurement.
Engine compression tests must be done as rapidly as possible.
(e) Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra load on the converter.
(f) Avoid coasting with ignition turned off and prolonged braking.
(g) Do not dispose of used catalyst along with parts contaminated with gasoline or oil.
