REPAIR INSTRUCTIONS
GENERAL INFORMATION
1. 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:
(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 ºº 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 ºº symbol.
(g) When necessary, use a sealer on gaskets to prevent
leaks.

FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG
(a) The TOYOTA SUPRA is equipped with an SRS (Supple-
mental Restraint System), such as the driver airbag, front
passenger 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-555).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the ºLOCKº 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 audio 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.

(f) 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 ºLOCKº posi-
tion and the negative (-) terminal cable is discon-
nected from the battery, even if only loosening the
set bolts of the 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 as shown on
page RS-38.
2. FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
If large amounts of unburned gasoline flow into the converter, it may overheat and create a fire hazard. 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.
3. IF VEHICLE IS EQUIPPED WITH MOBILE COMMUNICATION SYSTEM
(a) For vehicles with mobile communication systems such as two-way radios and cellular telephones, ob-
serve the following precautions.
(b) Install the antenna as far as possible away from the ECU and sensors of the vehicle's electronic sys-
tem.

(b) Measure resistance between terminals 1 and 2.
Standard resistance:
160 - 210 W at 20°C (68°F)
If resistance is not as specified, replace the sensor.
5. MAKE THESE VISUAL CHECKS:
(a) Leakage of grease from the clutch bearing
(b) Signs of oil on the pressure plate or rotor
6. INSPECT MAGNETIC CLUTCH BEARING FOR NOISE
(a) Start engine.
(b) Check for abnormal noise from the compressor when the
A/C switch is OFF.
If abnormal noise is being emitted, replace the magnetic clutch.
7. INSPECT MAGNETIC CLUTCH OPERATION
(a) Disconnect the connector.
(b) Connect the positive (+) lead from the battery to terminal
4 and the negative (-) lead to the body ground.
(c) Check that the magnetic clutch energized.
If operation is not as specified, replace the magnetic clutch.

BODY ELECTRICAL SYSTEM
PRECAUTION
Take care to observe the doing precautions when performing inspections or removal and replacement of
body electrical related parts.
1. HEADLIGHT SYSTEM
Halogen bulbs have pressurized gas inside and require special handling. They can burst if scratched or
dropped. Hold a bulb only by its plastic or metal case.
Don't touch the glass part of a bulb with bare hands.
2. SRS (SUPPLEMENTAL RESTRAINT SYSTEM)
The SUPRA is equipped with an SRS (Supplemental Restraint System) such as the driver airbag and front
passenger airbag. Failure to carry out service operation in the correct sequence could cause the SRS to
unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (including re-
moval or installation of parts, inspection or replacement), be sure to read the precautionary notices in the
RS section.
3. AUDIO SYSTEM
If the negative (-) terminal cable is disconnected from the battery, the preset AM, FM 1 and FM 2 sta-
tions stored in memory are erased, so be sure to note the stations and reset them after the battery
terminal is reconnected.
If the negative (-) terminal cable is disconnected from the battery, the ºANTI-THEFT SYSTEMº will
operate when the cable is reconnected, but the radio, tape player and CD player will not operate. Be
sure to input the correct ID number so that the radio, tape player and CD player can be operated again.
4. MOBILE COMMUNICATION SYSTEM
If the vehicle is equipped with a mobile communication system, refer to precautions in the IN section.
