1997 TOYOTA SUPRA suspension

36SUPRAÐNEW FEATURES
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.

23 SUPRAÐ NEW FEATURES
8. Suspension
Various areas of the suspension system have been revised to realize excellent riding comfort, in addition, this provides
excellent stability, and controllability.
9. Body

Reinforcements and gussets have been newly added to the bottom of the front and center pillars.

An energy absorbing pads are provided at the door trim.

Sound absorbing material is newly provided in the front pillar and in the quarter to reduce road noise.

The material of sound absorbing material used in the trim and garnish has been changed.
10.Light
An illuminated entry system has been discontinued.
11. SRS Airbag
As in the '95 Avalon, a 1±sensor type airbag system has been adopted.
12.Cruise Control System

As in the '97 Tercel/Paseo, a new motor type actuator has been adopted.

The control method for the manual and auto cancel functions have been changed.

3. DRIVE TRAIN AND CHASSIS2. BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and
notes given in section BR of the repair manual for the relevant model year when handling brake
system parts.
NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC
system.
The drive train and chassis are components-that can have great effects on the running performance
and vibration resistance of the vehicle. After installing components in the sections listed in the table
below, perform alignments to ensure correct mounting angles and dimensions. Particularly accurate
repair of the body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions
given in the repair manual for the relevant model year during alignment and section DI of this manual.

GENERAL INFORMATION
1. BASIC DIMENSIONS
(a) There are two types of dimensions in the diagram.
(Three-dimensional distance)

Straight-line distance between the centers of two
measuring points.
(Two-dimensional distance)

Horizontal distance in forward/rearward between
the centers of two measuring points.

The height from an imaginary standard line.
(b) In cases in which only one dimension is given, left
and right are symmetrical.
(c) The dimensions in the following drawing indicate
actual distance. Therefore, please use the dimen-
sions as a reference.
2. MEASURING
(a) Basically, all measurements are to be done with a
tracking gauge. For portions where it is not possible
to use a tracking gauge, a tape measure should be
used.
(b) Use only a tracking gauge that has no looseness in
the body, measuring plate, or pointers.
HINT:
1. The height of the left and right pointers must be equal.
2. Always calibrate the tracking gauge before measuring or
after adjusting the pointer height.
3. Take care not to drop the tracking gauge or otherwise
shock it.
4. Confirm that the pointers are securely in the holes.
(c) When using a tape measure, avoid twists and
bends in the tape.
(d) When tracking a diagonal measurement from the
front spring support inner hole to the suspension
member upper rear installation hole, measure
along the front spring support panel surface.
