WHEEL ALIGNMENT 2B-5
VIBRATION DIAGNOSIS
Wheel imbalance causes most highway speed vibration
problems. A vibration can remain after dynamic
balancing because:
lA tire is out of round.
lA rim is out of round.
lA tire stiffness variation exists.
Measuring tire and wheel free runout will uncover only
part of the problem, All three causes, known as loaded
radial runout, must be checked using method of
substituting known good tire and wheel assemblies on
the problem vehicle.
Preliminary Checks
Prior to performing any work, always road test the car
and perform a careful visual inspection for:
lObvious tire and wheel runout.
lObvious drive axle runout.
lImproper tire inflation.
lIncorrect trim height.
lBent or damaged wheels.
lDebris build-up on the tire or the wheel.
lIrregular or excessive tire wear.
lImproper tire bead seating on the rim,
lImperfections in the tires, including: tread
deformations, separations, or bulges from impact
damage. Slight sidewall indentations are normal and
will not affect ride quality.
Tire Balancing
Balance is the easiest procedure to perform and should
be done first if the vibration occurs at high speeds. Do
an off-vehicle, two-plane dynamic balance first to correct
any imbalance in the tire and wheel assembly.
An on-vehicle finish balance will correct any brake drum,
rotor, or wheel cover imbalance, If balancing does not
correct the high-speed vibration, or if the vibration occurs
at low speeds, runout is the probable cause.

PROPELLER SHAFT 3C-5
5. If difficult to remove, clamp the yoke side in a vise and tap
off the needle bearing, using a proper tool.
6. Disassemble the universal joint parts.
lAs axles move up and down, universal joints allow drive
angles to change without binding propeller shaft.

6 Snap Ring
4. Slightly tapping the yoke shoulder using a brass hammer,
remove the bearing. Remove the remaining bearings in the
same way.

POWER BOOSTER 4C-5
PEDAL STROKE INSPECTION
1. Start the engine and stop it after one or two minutes.
Depress the brake pedal several times.
If the pedal goes down furthest the first time, but gradually
rises after the second or third time, brake booster is normal.
If there is no change in pedal stroke, the brake booster is
abnormal.
2. Depress the brake pedal several times with engine stopped,
and depress the brake pedal and start the engine. If the
pedal goes down slightly, the booster is normal.
3. Depress the brake pedal with engine running, and stop it
with the pedal depressed. If there is no change in pedal
height during 30 sec., the booster is normal.

Initializing
1. Set the ignition switch n “ON” position.
2. Connect the No.1 terminal (Ground) and the No.13 (ABS)
from diagnosis socket located in E/G room by use of service
connector for 3 - 4 seconds and initialize the flash code.
Notice
Be careful not to connect over 5 seconds.
3. ABS indicator warning light continuously comes on until the
ignition switch is “OFF”.
Dignosis Table
1. When the system is normal
lOne pulse (normal code 01) indicates.
2. When the system is abnormal
lOne pulse (defect code) indicates.
Notice
Repeat the initializing procedure when checking the
defect code Defect code is indicated once for 1 sec (light
on : 0.75 sec, light off : 0.25 sec).
Removal the Defect Code
1. Repair the defect code and remove the memorized defect
code in the ECU.
2. Connect the No. 13 terminal (ABS) from diagnosis socket
and No. 1 terminal (ground) for over 5 seconds.
3. Set the ignition switch in the “OFF” position.
Notice
lDefect code will be memorized in ECU unless the defect
code is not removed.
lRepeat the initializing procedure and check the other
defects.

5A-20 AUTOMATIC TRANSMISSION
OPERATOR INTERFACES
There are three operator interfaces associated with the four speed transmission.
They are:
lThe gear select lever
lThe driving mode selector
lThe indicator light
These operator interfaces are described below.
GEAR SELECT LEVER OPERATION
The transmission uses a conventional selector lever. The selector lever can be moved from one position to another
within the staggered configuration of the selector lever gate to positively indicate the gear -selection as shown on
figure 2.1. For information about the gear selections available refer to table 2.1.

a function of vehicle speed. Engine braking is applied with reduced throttle.
First, second and third gear operation with an inhibited third gear engagement
at high vehicle speed. Refer to the vehicle owner’s manual.
Engine braking is applied with reduced throttle.
First, second, third and fourth gear operation. First to second (1-2), first to third

throttle position and the time rate of change of the throttle position (forced
downshift). Lockup clutch may be enabled in 3rd and 4th gears depending on
vehicle type. Refer to the owner’s manual.
Rear band applied only, with inhibited engagement as a function of vehicle
speed, engine speed and throttle position. The inhibitor switch allows the en-
gine to start.
Reverse gear operation, with inhibitor engagement as a function of vehicle
speed, engine speed and throttle position. The inhibitor switch enables reverse
lamp operation.
Rear band applied only, with inhibited engagement as a function of vehicle
speed, engine speed and throttle position. The transmission output shaft is
locked. The inhibitor switch allows the engine to start.
Table 2.1 - Gear Selections
DRIVING MODE SELECTOR
The driving mode selector consists of a mode selection switch and indicator light. The driving mode selector is
located on the centre console. See figure 2,1.
The schedules available to be selected vary with vehicle types. Typically the driver should have the option to select
between ‘NORMAL’ , ‘POWER’ or ‘WINTER’ modes.
When ‘NORMAL’ mode is selected upshifts will occur to maximise fuel economy and the indicator lights remain
extinguished. When ‘POWER’ mode is selected upshifts will occur to give maximum performance and the ‘POWER’
mode indicator light is switched on. When ‘WINTER’ mode is selected, starting at second gear is facilitated, the
‘WINTER’ mode indicator light is switched on and the ‘POWER’ mode indicator light is switched off.
Refer to the vehicle owner’s manual for specific modes for each vehicle type.
