3. Disconnect terminal cord assembly harness connector.
4. Remove snap ring from terminal body.
5. Remove terminal cord assembly by pushing terminal body into
transaxle case.
6. Remove engine under cover.
7. Remove front LH nut of front suspension member, and then
lower front LH of front suspension member to secure a space for
removing control valve assembly.
8. Drain ATF from A/T. Refer to AT- 1 5 , "
Changing A/T Fluid" .
9. Remove oil pan and oil pan gasket.
10. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.

If frictional material is detected, replace radiator after
repair of A/T. Refer to CO-13, "
RADIATOR" , CO-16,
"RADIATOR (ALUMINUM TYPE)" (QR engine) or CO-37,
"RADIATOR" , CO-40, "RADIATOR (ALUMINUM TYPE)"

DISPLAY
REAR VIEW MONITOR
Symptom Possible cause Possible solution
No image is displayed.The brightness is at the lowest setting. Adjust the brightness of the display.
The display is turned off. Turn on the display.
The screen is too dim. The move-
ment is slow.The temperature in the interior of the vehicle is
low.Wait until the interior of the vehicle has
warmed up.
Some pixels in the display are
darker or brighter than others.This condition is an inherent characteristic of
liquid crystal displays.This is not a malfunction.
Some menu items cannot be
selected.Some menu items become unavailable while
the vehicle is driven.Park the vehicle in a safe location, then oper-
ate the system.
Symptom Possible cause Possible solution
Rear view monitor image is not
shown.Selector lever is not set to R position. Shift the selector lever to R position.
Rear view monitor image is fuzzy.The front glass of the camera lens is dirty. Wipe it with a soft wet cloth lightly.
Adherence of raindrops or snow. Wipe it with a soft cloth lightly.
The lens is illuminated directly by sunlight or light

FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15 × 25 mm (0.59 × 0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll
The following materials, not available through NISSAN Parts Department, can also be used to repair squeaks
and rattles.
UHMW(TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit.
Note: Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle TroubleshootingBIS000VN
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. Cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks to
repair the noise.
