DIFFERENTIAL
1. General
A differential gear ratio has been changed on the 2JZ±GE engine model.
A Helical gear type torque±sensing LSD (Limited Slip Differential) is available as an option on the SJZ±GE engine
model and 2JZ±GTE engine with automatic transmission model.
As in the '96 model, a worm gear type torque±sensing LSD is used on the model with the SJZ±GTE engine and
manual transmission.

Characteristics
Good traction of high bias ratio design is obtained through the utilization of two types of friction: One is the friction
that is generated between the planet gear's tooth tips and the differential case's inner wall. The other is the friction
that is generated between the side gear end face and the thrust washer.
Quick response and minimum time lag until differential limiting force is generated.
The bias ratio sustains minimal changes due to aging and maintains a stable performance.
A simple, compact, and lightweight differential configuration has been achieved through the use of the helical gear.
Ordinary differential oil must be used; do not use special LSD oil.

3) ABS ECU
a. Wheel Speed Control
The ECU constantly receives signals form the 4±speed sensors and a deceleration sensor (2JZ±GTE engine model),
and estimates the speed and deceleration rate of the vehicle by calculating the speed and deceleration rate of each
wheel.
b. Initial Check
An initial check is carried out every time once after the engine has started and the initial vehicle speed exceeds 6 km/h
(4 mph).
c. Self±Diagnosis
If the ABS ECU detects a malfunction in the ABS, the ABS warning light and a master warning lights in the
combination meter will light up and alert the driver that a malfunction has occurred. The ECU will also store the codes
of the malfunctions.
SUSPENSION
1. General
The shock absorber of the 2JZ±GTE engine model with manual transmission has been changed from the
mono±tube, gas±filled shock absorber to the twin±tube, gas±filled shock absorber, which is the same type that is
used on the 2JZ±GE engine model.
The same rubber±integrated ball bushing that is used on the 2JZ±GTE engine model is used for the upper arm
bushing of the rear suspension of the 2JZ±GE engine model.
The brace rod of the rear subframe has been relocated to realize excellent riding comfort, in addition, this provides
excellent stability, an controllability.

INSPECTION
1. INSPECT SPEEDOMETER ON-VEHICLE
Using a speedometer tester, inspect the speedometer for allow-
able indication error and check the operation of the odometer.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.
If error is excessive, replace the speedometer.

2. INSPECT VEHICLE SPEED SENSOR OPERATION
(a) Connect the positive (+) lead from battery to terminal 1
and negative (-) lead to terminal 2.
(b) Connect the positive (+) lead from tester to terminal 3 and
negative (-) lead to terminal 2.
(c) Rotate shaft.
(d) Check that there is voltage change from approx. 0 V to 11
V or more between terminals 2 and 3.
HINT:
The voltage change should be 4 times for every revolution of
the speed sensor shaft.
If operation is not as specified, replace the sensor.
3. INSPECT TACHOMETER ON-VEHICLE
(a) Connect a tune-up test tachometer, and start the engine.
NOTICE:
Reversing the connection of the tachometer will damage
the transistors and diodes inside.
(b) Compare the tester and tachometer indications.
If error is excessive, replace the tachometer.

FOREWORD
This repair manual has been prepared to provide information on
the repair methods (including cutting and welding operations, but
excluding painting) for collision-damaged body components of the
TOYOTA SUPRA.
Applicable models: JZA80 series
This manual consists of body repair methods, exploded diagrams
and illustrations of the body components and other information re-
lating to body panel replacement such as handling precautions,
etc. However, it should be noted that the front fenders of the
TOYOTA models are bolted on and require no welding.
Body construction will sometimes differ depending on specifica-
tions and country of destination. Therefore, please keep in mind
that the information contained herein is based on vehicles for gen-
eral destinations.
For the repair procedures and specifications other than collisionda-
maged body components of the TOYOTA SUPRA refer to the fol-
lowing repair manuals.
If you require the above manuals, please contact your TOYOTA
Dealer.
All information contained in this manual is the most up-to-date at
the time of publication. However, specifications and procedures are
subject to change without prior notice.

COLLISION REPAIR INFORMATION
TITLE: URETHANE ADHESIVE SEALANT FOR PAGE 1 of 3
FIXED GLASS INSTALLATION
SECTION: STRUCTURAL REPAIR BULLETIN #31
MODELS: ALL
DATE: NOVEMBER 1988
In order to comply with FMVSS 212 ± Windshield Retention and FMVSS 216 ± Roof Crush
Resistance, the factory uses a urethane adhesive sealant with bonded strength of not less
than 40 kilograms per square centimeter or 569
pounds per square inch for certain bonded
windshields and rear windows on Toyota vehicles.
A Urethane adhesive sealant of at least equivalent strength must
be used to maintain
these retention and roof crush standards when windshield glass replacements are
performed by either the dealer or an outside glass shop.
Since the adhesive kits listed in Toyota Repair Manuals are not available in the U.S.A.
, a
listing of some locally available equivalent materials is provided below. Be sure to follow
the sealant manufacturer's instructions for best results.
CVS Urethane Auto Glass Sealer by American Sure Seal
Bonding strength = 600 pounds per square in. (approximate)
Super Fast Urethane by 3M
Bonding strength = 1000 pounds per square in. (approximate)
Unrest 212 by Kent Industries
Bonding strength = 600 pounds per square in. (approximate)
Urethane E Auto Glass Sealer by Protective Treatment Inc.
Bonding strength = 600 pounds per square in. (approximate)
For more detailed application information, see the attached ªUrethane Adhesive Sealant
Application for Toyota Modelsº.
Rear quarter windows on some models are bonded, however, the adhesive for these
windows requires less bonding strength and therefore, use of Butyl sealer may be sufficient
for these windows.
This bulletin is for information and clarification purposes only. Existing Warranty policy and
Flat Rate information have not been changed. Toyota is not responsible for problems that
occur from usage of improper sealants or procedures which fail to meet Toyota
specifications. PLEASE CONSULT THE APPROPRIATE TOYOTA SERVICE MANUAL
FOR THE PROPER REPAIR PROCEDURES.

DTC P0125 Insufficient Coolant Temp. for Closed Loop
Fuel Control
CIRCUIT DESCRIPTION
To obtain a high purification rate for the CO, HC and NOx components of the exhaust gas, a three-way cata-
lytic converter is used, but for the most efficient use of the three-way catalytic converter, the air-fuel ratio
must be precisely controlled so that it is always close to the stoichiometric air-fuel ratio.
The oxygen sensor has the characteristic whereby its output voltage changes suddenly in the vicinity of the
stoichiometric air-fuel ratio. This characteristic is used to detect the oxygen concentration in the exhaust
gas and provide feedback to the computer for control of the air-fuel ratio.
When the air-fuel ratio becomes LEAN, the oxygen concentration in the exhaust increases and the oxygen
sensor informs the ECM of the LEAN condition (small electromotive force: 0 V).
When the air-fuel ratio is RICHER than the stoichiometric air-fuel ratio the oxygen concentration in the ex-
haust gas is reduced and the oxygen sensor informs the ECM of the RICH condition (large electromotive
force: 1 V).
The ECM judges by the electromotive force from the oxygen sensor whether the air-fuel ratio is RICH or
LEAN and controls the injection time accordingly. However, if malfunction of the oxygen sensor causes out-
put of abnormal electromotive force, the ECM is unable to perform accurate air-fuel ratio control.
The heated oxygen sensors include a heater which heats the Zirconia element. The heater is controlled by
the ECM. When the intake air volume is low (the temperature of the exhaust gas is low) current flows to the
heater to heat the sensor for accurate oxygen concentration detection.

After the engine is warmed up, heated oxygen sensor output
does not indicate RICH even once when conditions (a), (b) and
(c) continue for at least 2 min. :
(a) Engine speed: 1,500 rpm or more
(b) Vehicle speed: 40 - 100 km/h (25 - 62 mph)
(c) Closed throttle position SW: OFF

After confirming DTC P0125 use the OBD II scan tool or TOYOTA hand-held tester to confirm voltage output
of heated oxygen sensor from ºCURRENT DATAº.
If voltage output of heated oxygen sensor is 0 V, heated oxygen sensor circuit may be open or short.
