REMOTE KEYLESS ENTRY SYSTEM
Revision: October 20052005 QX56
NOTE:

If a keyfob is lost, the ID code of the lost keyfob must be erased to prevent unauthorized use. A specific ID
code can be erased with CONSULT-II. However, when the ID code of a lost keyfob is not known, all con-
troller ID codes should be erased. After all ID codes are erased, the ID codes of all remaining and/or new
keyfobs must be re-registered.
To erase all ID codes in memory, register one ID code (keyfob) five times. After all ID codes are erased,
the ID codes of all remaining and/or new keyfobs must be re-registered.

When registering an additional keyfob, the existing ID codes in memory may or may not be erased. If five
ID codes are stored in memory, when an additional code is registered, only the oldest code is erased. If
less than five ID codes are stored in memory, when an additional ID code is registered, the new ID code is
added and no ID codes are erased.

If you need to activate more than two additional new keyfobs, repeat the procedure “Additional ID code
entry” for each new keyfob.

Entry of maximum five ID codes is allowed. When more than five ID codes are entered, the oldest ID code
will be erased.

Even if same ID code that is already in the memory is input, the same ID code can be entered. The code
is counted as an additional code.

DTC P0456 EVAP CONTROL SYSTEM
2005 QX56
CAUTION:

Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used,
the MIL may come on.

If the fuel filler cap is not tightened properly, the MIL may come on.

Use only a genuine NISSAN rubber tube as a replacement.
DTC Confirmation ProcedureUBS00H5U
NOTE:

If DTC P0456 is displayed with P0442, first perform trouble diagnosis for DTC P0456.

After repair, make sure that the hoses and clips are installed properly.

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait
at least 10 seconds before conducting the next test.
TESTING CONDITION:

Open engine hood before conducting following procedure.

If any of following conditions are met just before the DTC confirmation procedure, leave the vehi-
cle for more than 1 hour.
–Fuel filler cap is removed.
–Fuel is refilled or drained.
–EVAP component parts is/are removed.

Before performing the following procedure, confirm that battery voltage is more than 11V at idle.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-II.
2. Make sure the following conditions are met.
FUEL LEVEL SE: 0.25 - 1.4V
COOLAN TEMP/S: 0 - 32°C (32 - 90°F)
FUEL T/TMP SE: 0 - 35°C (32 - 95°F)
INT/A TEMP SE: More than 0°C (32°F)
If NG, turn ignition switch OFF and leave the vehicle in a cool place (soak the vehicle) or refilling/draining
fuel until the output voltage condition of the “FUEL LEVEL SE” meets within the range above and leave
the vehicle for more than 1 hour. Then start from step 1).
3. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
4. Select “EVAP V/S LEAK P0456/P1456” of “EVAPORATIVE SYSTEM” in “DTC WORK SUPPORT” mode
with CONSULT-II.
Follow the instruction displayed.
5. Make sure that “OK” is displayed.
If “NG” is displayed, refer to EC-360, "
Diagnostic Procedure" .
NOTE:

If the engine speed cannot be maintained within the range displayed on CONSULT-II screen, go
to EC-72, "
Basic Inspection" .

Make sure that EVAP hoses are connected to EVAP canister purge volume control solenoid
valve properly.

5. Install the camshaft sprockets using the following procedure:
a. Install the camshaft sprockets aligning them with the matching
marks painted on the timing chain when removed. Align the
camshaft sprocket key groove with the dowel pin on the cam-
shaft front edge at the same time. Then temporarily tighten
bolts.

Install the intake and exhaust side camshaft sprockets by
selectively using the groove of the dowel pin according to the
bank. (Common part used for both banks.)
b. Lock the hexagonal part of the camshaft in the same way as for
removal, and tighten the bolts.
c. Check again that the timing mating mark on the timing chain and
on each sprocket are aligned.
6. Install the chain tensioner using the following procedure:
NOTE:
Left bank is shown.
a. Install the chain tensioner.

Compress the plunger and hold it using a stopper pin when
installing.

Loosen the slack guide side timing chain by rotating the cam-
shaft hexagonal part if mounting space is small.
b. Remove the stopper pin and release the plunger, and then apply
tension to the timing chain.
c. Install the chain tensioner cover onto the front cover (RH bank).

Apply liquid gasket as shown.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-45, "
Recommended Chemical Products and Sealants"
.
7. Check and adjust valve clearances. Refer to EM-51, "
Va l v e
Clearance" .
8. Installation of the remaining components is in the reverse order
of removal.

INSPECTION
NOTE:
Perform the following inspection after removal, installation or replacement of camshaft or valve-related parts,
or if there are unusual engine conditions due to changes in valve clearance over time (starting, idling, and/or
noise).
1. Warm up the engine. Then stop the engine.
2. Remove the engine cover, battery cover and air duct assembly. Refer to EM-11, "
Removal and Installa-
tion" , SC-9, "REMOVAL" and EM-14, "Removal and Installation" .

CONSULT-II CHECKING SYSTEM
Revision: October 20052005 QX56
Nickel Metal Hydride Battery Replacement EAS001XT
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WAR NIN G:
Replace the nickel metal hydride battery with Genuine CONSULT-II battery only. Use of another bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if
mistreated. Do not recharge, disassemble or dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.
Checking EquipmentEAS001XU
When ordering the below equipment, contact your NISSAN distributor.
CAUTION:

Previous 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.

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self- diagnosis depending on control unit which carries out CAN communication.

If CONSULT-II CONVERTER is not connected with CONSULT-II, the vehicle enters “FAIL SAFE
MODE” which will “LIGHT UP the HEAD LIGHT” and /or “COOLING FAN ROTATING” when CON-
SULT-II is started.
NOTE:

The CONSULT-II must be used in conjunction with a program card.
CONSULT-II does not require loading (Initialization) procedure.

Be sure the CONSULT-II is turned OFF before installing or removing a program card.
CONSULT-II Start ProcedureEAS001XV
NOTE:
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.
Tool name Description
NISSAN CONSULT-II (J-44200)
1. CONSULT-II unit (Tester internal soft: Resident
Version 3.4.0) and accessories.
2. Program card UED05B-1 and AEN04A-1 (for
NATS) or later, to confirm the best combination
of these software, refer to CONSULT-II Opera-
tion Manual.
3. CONSULT-II CONVERTER.
4. "CONSULT-II pigtail" cable.
