Self-Diagnosis ModeBKS0027X
DIAGNOSIS PROCEDURE
1. Select “DCU Failure Diagnosis”.

Self-diagnosis screen is displayed, and then self-diagnosis
starts.

The bar graph visible below self-diagnosis screen displays
progress of the diagnosis.
2. When exiting self-diagnosis, a confirmation screen for unit con-
nection may be displayed.

When judging an optional device as an abnormal connection,
a confirmation screen is displayed to check if the applicable
device is actually equipped. When it is equipped, a screen for
diagnosis results is displayed by selecting the device name
and by selecting “Finish”. (Unequipped units can also be dis-
played by option.)

When optional device is connected normally, the switch of the
device name is not displayed.
3. On the diagnosis results screen, each unit name and connection
line will be colored according to the diagnosis result, as follows.
NOTE:

DCU = Display control unit

SW = A/C and AV switch

If multiple malfunctions occur at the same time for a single
unit, the screen switch colors are determined according to the following order of priority: red > yellow >
gray.

Screen when it is normal
–Between DCU and SW is connected in a gray.
–Between DCU and DISPLAY, DCU and AUDIO, AUDIO and CD-CHG are connected in green.
4. Select a switch on the diagnosis results screen, and comments
for the diagnosis results will be shown.

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.

CVT SHIFT LOCK SYSTEM

CVT SHIFT LOCK SYSTEMPFP:00000
DescriptionBCS001MP

The electrical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, the selector lever cannot be shifted from “P” (parking) to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless the selector lever is placed in “P”.

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder, respectively.
Shift Lock System Electrical Parts LocationBCS001MQ
NOTE:
This emergency lever can be used when battery is off ignition key cannot be removed. In the situation like this,
by operating this lever, ignition key can be removed.
