TWEEN RIGHT AND LEFT
DescriptionINFOID:0000000005931265
Unbalance steering wheel turning force and return between right and left.
Diagnosis ProcedureINFOID:0000000005931266
1.CHECK THE ILLUMINATION OF THE EPS WARNING LAMP
Check that the EPS warning lamp turns ON when igni tion switch turns ON. Then, EPS warning lamp turns
OFF after the engine is started.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Refer to STC-26, "
Diagnosis Procedure".
2.CHECK WHEEL ALIGNMENT
1. Check the wheel alignment. Refer to FSU-7, "
On-Vehicle Inspection and Service".
2. Perform EPS control unit self-diagnosis.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Adjustment of wheel alignment.
3.CHECK EPS CONTROL UNIT SIGNAL
With CONSULT-III
1. Start the engine. CAUTION:
Stop the vehicle.
2. Turn steering wheel from full left stop to full right stop.
3. Select “TORQUE SENSOR” of “DATA MONITOR” for EPS control unit.
Is the inspection result normal?
YES >> GO TO 5.
NO >> GO TO 4.
4.CHECK EPS MOTOR
Perform the trouble diagnosis of EPS motor. Refer to STC-13, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair or replace the specific malfunctioning part.
5.CHECK STEERING WHEEL TURNING FORCE
Check the steering wheel turning force. Refer to PS-6, "
On-Vehicle Inspection and Service".
Is the inspection result normal?
YES >> Inspection End.
NO >> Check the steering wheel turning force for mechanical malfunction. Refer to PS-6, "
On-Vehicle
Inspection and Service".

ROAD WHEEL TIRE ASSEMBLY
4. If calculated balance weight value exceeds 50 g (1.76 oz), installtwo balance weight sheets in line with each other as shown.
CAUTION:
Do not install one balance weight sheet on top another.
5. Start balancer machine again.
6. Install balance weight on inner side of road wheel in the bal- ancer machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
7. Start balancer machine. Make sure that inner and outer residual imbalance values are 5 g (0.17 oz) each or below.
8. If either residual imbalance value exceeds 5 g (0.17 oz), repeat installation procedures.
TIRE ROTATION
• Follow the maintenance schedule for tire rotation service intervals.
Refer to MA-7, "
General Maintenance".
• When installing the wheel, tighten wheel nuts to the specified
torque.
CAUTION:
• Do not include the T-type spare tire when rotating the tires.
• When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
• Be careful not to tighten wheel nut at torque exceeding the criteria for preventing strain of disc rotor.
• Use NISSAN genuine wheel nuts for aluminum wheels.
• Perform the ID registration, after tire rotation. Refer to WT-13, "
ID Registration Procedure".
