CONSULT-II CHECKING SYSTEMPFP:00000
DescriptionEAS001H2
lCONSULT-II is a hand-held type tester. When it is connected with a diagnostic connector equipped on the
vehicle side, it will communicate with the control unit equipped in the vehicle and then enable various
kinds of diagnostic tests.
lRefer to “CONSULT-II Software Operation Manual” for more information.

Checking EquipmentEAS001H5
When ordering the following equipment, contact your NISSAN/INFINITI distributor.
CAUTION:
lPrevious CONSULT-II “I” and “Y” DLC-I and DLC-II cables should NOT be used anymore because
their DDL connector pins can be damaged during cable swapping.
lIf CONSULT-ll is used with no connection of CONSULT-ll CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
lIf CONVERTER is not connected with CONSULT-ll, vehicle occur the "FAIL-SAFE MODE" which is
"LIGHT UP the HEADLIGHT" and/or "Cooling FAN ROTATING" when CONSULT-ll is started.
NOTE:
lThe CONSULT-II must be used in conjunction with a program card.
CONSULT-II does not require loading (Initialization) procedure.
lBe sure the CONSULT-II is turned off before installing or removing a program card.
CONSULT-II Start ProcedureEAS001H6
Turning ignition switch off when performing CAN diagnosis could cause CAN memory to be erased.
1. Connect CONSULT-II and CONSULT-II CONVERTER to the
data link connector.
2. If necessary, turn on the ignition switch.
3. Touch “START (NISSAN BASED VHCL)” or System Shortcut
key (e.g.: Engine) on the screen.

INSPECTION PROCEDURE
If the CONSULT-II cannot diagnose the system properly, check the following items.
NOTE:
The DDL1 and DDL2 circuits from DLC pins 12, 13, 14 and 15 may be connected to more than one system. A
short in a DDL circuit connected to a control unit in one system may affect CONSULT-II access to other sys-
tems.
Symptom Check item
CONSULT-II cannot access
any system.
lCONSULT-II DLC power supply circuit (Terminal 8) and ground circuit (Terminal 4) (For detailed
circuit, refer to “MIL & Data Link Connectors Wiring Diagram” in EC section.)
lCONSULT-II DLC cable and CONSULT-II CONVERTER.
CONSULT-II cannot access
individual system. (Other sys-
tems can be accessed.)
lCONSULT-II program card (Check the appropriate CONSULT-II program card for the system.
Refer to "Checking Equipment".)
lPower supply and ground circuit for the control unit of the system (For detailed circuit, refer to wir-
ing diagram for each system.)
lOpen or short circuit between the system and CONSULT-II DLC (For detailed circuit, refer to wiring
diagram for each system.)
lOpen or short circuit CAN communication. Refer toLAN-3, "Precautions When Using CONSULT-
II"

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
Usetoeliminatemovement.
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 TroubleshootingEIS00C03
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
applying felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate
wiring harness.
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.
