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 location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-
cate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-clutch on M/T models, drive position on A/T models).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.

Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.

If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool
(Engine Ear or mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:

removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fastener can be broken
or lost during the repair, resulting in the creation of new noise.

tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only
temporarily.

feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.

placing a piece of paper between components that you suspect are causing the noise.

looking for loose components and contact marks.
Refer to IP-6, "
Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE

If the cause is a loose component, tighten the component securely.

If the cause is insufficient clearance between components:
–separate components by repositioning or loosening and retightening the component, if possible.
–insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or ure-
thane tape are available through your authorized Nissan Parts Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
Always check with the Parts Department for the latest parts information.
Each item can be ordered separately as needed.

HEADLAMP AIMING CONTROL (AUTO)

System DescriptionBKS002BA
The height sensor is located on the right side of the rear suspension member. With the lighting switch in the
1ST or 2ND position, the height sensor detects vehicle height change by sensing the displacement of the sus-
pension arm. And the height sensor transmits a corresponding signal to the headlamp aiming motors. The sig-
nal drives the headlamp aiming motors, which adjusts the low beam reflector of each headlamp to an angle
appropriate for the vehicle height.
The aiming motor drive signal level retains when the following conditions are not met.

When the stopped vehicle changes the height and keeps it for more than 10 seconds, the height sensor
outputs a aiming motor drive signal. And height sensor keeps signal voltage to headlamp aiming motor.
Upon reception of the aiming motor drive signal, both headlamp aiming motors cause the low beam reflec-
tors to move to the position commanded by the signal.

When the vehicle is running (excluded when accelerating/decelerating), the height sensor transmits aim-
ing motor drive signal to headlamp aiming motors at the predetermined intervals. The voltage level of
every signal input is maintained unchanged until the next signal is input.
Upon reception of the aiming motor drive signal, both headlamp aiming motors cause the low beam reflec-
tors to move to the position commanded by the signal.

When the vehicle is accelerating or decelerating, the height sensor keeps the same aiming motor drive
signal voltage level rather than changing it, so that the low beam reflectors of both headlamps do not
operate.
When the lighting switch is turned OFF position, the height sensor retains the aiming motor drive signal level
at that moment and stops transmitting the signal.

Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE

Check engine oil for white turbidity or heavy contamination.

If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

Intake valve timing control cover and intake valve timing control solenoid valve

Front cover

Mating surface between cylinder block and lower cylinder block

Mating surface between cylinder block and cylinder head

OIL PRESSURE CHECK
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Engine oil pressure check should be in “ Parking position”.
1. Check engine oil level. Refer to LU-7, "

2. Remove splash guard (RH).
3. Disconnect harness connector at oil pressure switch, and
remove oil pressure switch using deep socket (commercial ser-
vice tool).
