1.SUNROOF SWITCH INPUT SIGNAL CHECK
Work item Description
RETAINED PWR SET RAP signal’s power supply period can be changed by mode setting. Selects RAP sig-
nal’s power supply period between the following three steps.
• MODE 1 (45 sec.) / MODE 2 (OFF) / MODE 3 (2 min.)
Test item
Description
RETAINED PWR This test is able to supply RAP signal (power) from BCM to power window system,
power sunroof system. Those systems can be operated when turning on "RETAINED
PWR" on CONSULT-III screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-III can be operated with ignition switch in "OFF" po-
sition. "RETAINED PWR" should be turned "ON" or "OFF" on CONSULT-III
screen when ignition switch ON. Then turn ignition switch OFF for checking re-
tained power operation. CONSULT-III might be stuck if "RETAINED PWR" is
turned "ON" or "OFF" on CONSULT-III screen when ignition switch is OFF.
Monitored item
Description
IGN ON SW Indicates [ON/OFF] condition of ignition switch.
DOOR SW-DR Indicates [ON/OFF] condition of front door switch LH.
DOOR SW-AS Indicates [ON/OFF] condition of front door switch RH.

5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Rear SuspensionINFOID:0000000005397074
• When installing the rubber bushings, the final tightening must be done under unladen condition and with the
tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immediately.
• Unladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The spare
tire, jack, hand tools, and mats are in their designated positions.
• After installing suspension components, check the wheel alignment.
• Caulking nuts are not reusable. Always use new caulking nuts for installation. New caulking nuts are pre- oiled, do not apply any additional lubrication.

REAR SUSPENSION ASSEMBLY
On-Vehicle Inspection and ServiceINFOID:0000000005397077
Make sure the mounting conditions (looseness, backlash) of each component and component conditions
(wear, damage) are within specifications.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace it if necessary.
Wheel AlignmentInspectionINFOID:0000000005397078
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-6
.
3. Wheel bearing axial end play. Refer to RAX-6, "
On-Vehicle Inspection and Service" .
4. Shock absorber operation.
5. Each mounting part of suspension for looseness and deformation.
6. Rear suspension beam for cracks, deformation, and other damage.
7. Vehicle height (posture).
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed. • This type of alignment is recommended for any NISSAN vehicle.
• The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.
• The alignment machine itself should be ca pable of accepting any NISSAN vehicle.
• The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated. • Your alignment machine should be regularly calibrated in order to give correct information.
• Check with the manufacturer of your specific al ignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-13, "Wheel
Alignment (Unladen*)" .
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or minus, Go/No Go). Do NOT use these indicators.
• The alignment specifications programmed into your alignment machine that operate these indicators may not be correct.
• This may result in an ERROR.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com- pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.
• Use the “Jacking Compensation” method. After inst alling the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
• See Instructions in the alignment machine you are using for more information.

from rear suspension beam. Refer to RSU-8, "
Component".
11. Remove brake tube protector from rear suspension beam.
INSPECTION AFTER REMOVAL
Check components for deformation, cracks, and other damage, and replace if necessary.
INSTALLATION
Installation is in the reverse order of removal.
• For tightening torque, refer to RSU-8, "
Component".
• Refill with new brake fluid and bleed air. Refer to BR-9, "
Bleeding Brake System".
• Tighten wheel nuts to specification. Refer to WT-7, "
Adjustment".
• Check the following after finishing work.
- Parking brake operation (stroke): Refer to PB-5, "
On-Vehicle Service".
- Wheel sensor harness for proper connection: Refer to BRC-34, "
Removal and Installation".
• Perform final tightening of rear suspension beam and rear suspen-
sion beam bracket (rubber bushing) under unladen conditions with
tires on level ground.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Work FlowINFOID:0000000005396865
CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interv iew to document the facts and conditions when the noise occurs and any
customer's comments; refer to SE-9, "
Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
• The customer may not be able to provide a detailed descr iption or the location of the noise. Attempt to obtain
all the facts and conditions that exist when the noise occurs (or does not occur).
• If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer is
concerned about. This can be accomplished by test driving the vehicle with the customer.
• After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
• Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces
= higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
• Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow mo vement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.
• Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contac t/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
• Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/someti mes repeating/often brought on by driver action.
• Tick—(Like a clock second hand) Tick characteristics include gentle contacting of li ght materials/loose components/can be caused by driver
action or road conditions.
• Thump—(Heavy, muffled knock noise) Thump characteristics include softer k nock/dead sound often brought on by activity.
• Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
• Often the degree of acceptable noise level will vary depending upon the person. A noise that you may judge as acceptable may be very irritating to the customer.
• Weather conditions, especially humidity and temperature, may have a great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or lo cation of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
