damage that may have contributed to the tire wear.
Correct the suspension concerns and Install new tires.

Go to K6.
SUBSTITUTE THE WHEELS AND TIRE
Page 501 of 1575
a.Substitute a known good set of wheels and tires.
b. Perform a road test.
c. If the vehicle still exhibits a shake or vibration, note the vehicle speed
and/or engine rpm which it occurs.
● Is the vibration felt ?
→ YES
Engine/transmission imbalance.
See the specification of TR group, EM group, FL group and EC group.
→ NO
Install the original tire/wheel assemblies one by one, Road testing at
each step until the damaged tire(s)/wheel(s) as necessary. Test the
system for normal operation.
Wheel /tire noise, vibration and harshness concerns are directly related to vehicle speed and are not generally affected
by acceleration, coasting or decelerating. Also, out - of- balance wheel and tires can vibrate at more than one speed. A
vibration that is affected by the engine rpm, or is eliminated by placing the transmission in Neutral is not related to the
tire and wheel. As a general rule, tire and wheel vibrations felt in the steering wheel are related to the front tire and
wheel assemblies. Vibrations felt in the seat or floor are related to the rear tire and wheel assemblies. This can initially
isolate a concern to the front or rear.
Careful attention must be paid to the tire and wheels. There are several symptoms that can be caused by damaged or
worn tire and wheels. Perform a careful visual inspection of the tires and wheel assemblies. Spin the tires slowly and
watch for signs of lateral or radial runout. Refer to the tire wear chart to determine the tire wear conditions and actions WHEEL AND TIRE DIAGNOSIS

WHEEL ALIGNMENT
When using commercially available computerized four wheel alignment equipment (caster, camber, toe) to inspect the
front wheel alignment, always position the car on a level surface with the front wheels facing straight ahead.
Prior to inspection, make sure that the front suspension and steering system are in normal operating condition and
that the wheels and tires face straight ahead and the tires are inflated to the specified pressure.
TOE
Toe is a measurement of how much the front of the wheels are turned in or out from the straight- ahead position.
Item Description
A - B < 0 Positive (+) toe (toe in)
A - B > 0 Negative ( - ) toe (toe out)
When the wheels are turned in toward the front of the vehicle, toe is positive (+) (toe in). When the wheels are turned
out toward the front of the vehicle, toe is negative(- ) (toe out). Toe is measured in degrees, from side to side, and
totaled.
[FRONT]
Toe- in(B - A or angle a+b) is adjusted by turning the tie rod turnbuckles. Toe- in on the left front wheel can be reduced
by turning the tie rod toward the rear of the car. Toe- in change is adjusted by turning the tie rods for the right and left
heels simultaneously at the same amount as follows.
Standard value :
Toe- in (B- A) mm (in) : 0 ± 2 (0 ± 0.0787)
a. Toe- in adjustment should be made by turning the right and left tie rods at the same amount.
b. When adjusting toe - in, loosen the outer bellows clip to prevent twisting the bellows.
c. After the adjustment, tighten the tie rod end lock nuts firmly and reinstall the bellows clip.
d. Adjust each toe - in to be the range of ±1mm.

the bent or damaged parts.
Caster : 3°46´ ± 30´ (to ground), 4°40´ (to body)
a.The worn loose or damaged parts of the front suspension assembly must be replaced prior to measuring front
wheel alignment.
b. Caster are pre- set to the specified value at the factory and don't need to be adjusted.
c. If the caster are not within specifications, replace bent or damaged parts.
d. The difference of left and right wheels about the the caster must be within the range of 0° ± 30´.
WHEEL RUNOUT
1.Jack up the vehicle and support it with jack stands.
2. Measure the wheel runout with a dial indicator as illustrated.
3. Replace the wheel if the wheel runout exceeds the limit.

STANDARD FLOW OF DIAGNOSTIC TROUBLESHOOTING
NOTES WITH REGARD TO DIAGNOSIS
The phenomena listed in the following table are not abnormal.
Phenomenon Explanation
System check sound When starting the engine, a thudding sound can sometimes be heard coming
from inside the engine compartment. This is because the system operation check
is being performed.
ABS operation sound a.Sound of the motor inside the ABS hydraulic unit operation (whine).
b. Sound is generated along with vibration of the brake pedal (scraping).
c. When ABS operates, sound is generated from the vehicle chassis due to
repeated brake application and release
(Thump : suspension; squeak: tires)
ABS operation (Long braking
distance) For road surfaces such as snow- covered and gravel roads, the braking distance
for vehicles with ABS can sometimes be longer than that for other vehicles.
Accordingly, advise the customer to drive safely on such roads by lowering the
vehicle speed.
Diagnosis detection conditions can vary depending on the diagnosis code. When checking the trouble symptom after
the diagnosis code has been erased, ensure that the requirements listed in "Comment" are met.
SCAN TOOL (PRO) CHECK
1. Turn the ignition switch OFF.
2. Connector the Scan tool to the 16P data link connector located the driver's side kick panel.

Error conditionBelow 6 pulses in 2 sec. Below 6 pulses in 1 sec.
Prerequisite FR/RR limit SW on Limit setting complete
a. Stop the related motor(seat / pedal) if an error is detected during playing or Easy access function operation.
b. Stop the corresponding motor if an error is detected during manual operation (excluding slide motor).
b. If seat sensor Vcc below 1V is detected by 1s
a. Stop all seat motors running if seat sensor Vcc error is detected during playing or Easy access function operation.
(no buzzer output)
c. Return if seat sensor Vcc is 4V or more.
DETECTING ERRORS FOR ADJUST PEDAL
1.If signal change is below 0.06V per sec though motor is running.
a. Stop the corresponding motor if error is detected during playing or Easy access function operation.
2. If adjust pedal sensor Vcc below 1V is detected by 1s
a. Stop pedal motor running if pedal sensor Vcc error is detected during playing or Easy access function operation.
(no buzzer output)
3. Return if adjust pedal sensor Vcc is 4V or more.
HANDLING ERRORS
1.If errors are discovered, regard them as harness disconnection or sensor failure, and conduct the following
measures.
a. Stop auto control (play or Easy access function operation) if it is under auto control and set off buzzer 10 times
(however, have motors other than the one with an error operate normally).
b. Set off alarm again in case of recurrence of error after restoration of a motor with an error.
c. Complete alarm 10 times though it comes back to normal during error alarm.
d. Stop alarm if receiving memory recall or play order, and set off buzzer in the corresponding function.
e. Manual operation control is allowed even for a motor with errors.
f. Set off buzzer if memory or play order is received even during error.
g. The timing to lift auto control suspension is when repair for the failing motor is completed, and the criteria for
the completion point are as follows:
a. Seat: if signal input is normal with over 6 pulses within a sec. from position sensor of a motor with an error
caused by manual switch.
b. Adjust pedal: if there is change in input of over 3 LSB within 1 sec. from sensor by manual switch.
