2006 NISSAN PATROL main

REMOVAL
After removing moldings, remove glass using piano wire or power
cutting tool and an in¯atable pump bag.
WARNING:
When cutting the glass from the vehicle, always wear safety
glasses and heavy gloves to help prevent glass splinters from
entering your eyes or cutting your hands.
CAUTION:
+Be careful not to scratch the glass when removing.
+Do not set or stand the glass on its edge. Small chips may
develop into cracks.
INSTALLATION
+Use a genuine Nissan Urethane Adhesive Kit or equivalent
and follow the instructions furnished with it.
+While the urethane adhesive is curing, open a door win-
dow. This will prevent the glass from being forced out by
passenger compartment air pressure when a door is
closed.
+The molding must be installed securely so that it is in
position and leaves no gap.
+Inform the customer that the vehicle should remain sta-
tionary until the urethane adhesive has completely cured
(preferably 24 hours). Curing time varies with temperature
and humidity.
WARNING:
+Keep heat and open ¯ames away as primers and adhesive
are ¯ammable.
+The materials contained in the kit are harmful if swallowed,
and may irritate skin and eyes. Avoid contact with the skin
and eyes.
+Use in an open, well ventilated location. Avoid breathing
the vapors. They can be harmful if inhaled. If affected by
vapor inhalation, immediately move to an area with fresh
air.
+Driving the vehicle before the urethane adhesive has com-
pletely cured may affect the performance of the windshield
in case of an accident.
CAUTION:
+Do not use an adhesive which is past its usable term. Shelf
life of this product is limited to six months after the date
of manufacture. Carefully adhere to the expiration or
manufacture date printed on the box.
+Keep primers and adhesive in a cool, dry place. Ideally,
they should be stored in a refrigerator.
+Do not leave primers or adhesive cartridge unattended
with their caps open or off.
+The vehicle should not be driven for at least 24 hours or
until the urethane adhesive has completely cured. Curing
time varies depending on temperature and humidities. The
curing time will increase under higher temperatures and
lower humidities.

Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The composition var-
ies according to the destination.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
+To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag in¯ation, all maintenance must be performed
by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the RS section.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation either just before
the harness connectors or for the complete harness are related to the SRS.
PRECAUTIONS AND PREPARATION
EC-4

Test and Adjustment
WARNING:
When using nozzle tester, be careful not to allow diesel fuel
sprayed from nozzle to contact your hands or body, and make
sure your eyes are properly protected with goggles.
INJECTION PRESSURE TEST
1. Install nozzle to injection nozzle tester and bleed air from ¯are
nut.
2. Pump the tester handle slowly (one time per second) and watch
the pressure gauge.
3. Read the pressure gauge when the injection pressure just
starts dropping.
Initial injection pressure:
Used
14,220 kPa (142.2 bar, 145 kg/cm
2, 2,062 psi)
New
14,711 - 15,495 kPa (147.1 - 155.0 bar,
150 - 158 kg/cm
2, 2,133 - 2,247 psi)
Always check initial injection pressure using a new nozzle.
4. To adjust injection pressure, change adjusting shims (No. 2 - 4
nozzles).
a. Increasing the thickness of adjusting shims increases ini-
tial injection pressure. Decreasing thickness reduces ini-
tial pressure.
b. A shim thickness of 0.04 mm (0.0016 in) corresponds
approximately to a difference of 471 kPa (4.71 bar, 4.8
kg/cm
2, 68 psi) in initial injection pressure.
Refer to SDS for adjusting shim (EC-189).
LEAKAGE TEST
1. Maintain the pressure at about 981 to 1,961 kPa (9.8 to 19.6
bar, 10 to 20 kg/cm2, 142 to 284 psi) below initial injection
pressure.
2. Check that there is no dripping from the nozzle tip or around the
body.

3. If there is leakage, clean, overhaul or replace nozzle.
SPRAY PATTERN TEST
1. Check spray pattern by pumping tester handle one full stroke
per second.
+If main spray angle is within 30 degrees as shown, injec-
tion nozzle is good.
+It is still normal even if a thin stream of spray deviates from
the main spray (pattern B).
2. If the spray pattern is not correct, disassemble and clean
nozzle.
3. Test again and if spray pattern is not corrected, replace nozzle.

Malfunction Indicator Lamp (MIL)
1. The malfunction indicator lamp will light up when the ignition
switch is turned ON without the engine running. This is a bulb
check.
+If the malfunction indicator lamp does not light up, refer to EL
section (``WARNING LAMPS AND CHIME'') or see EC-188.
2. When the engine is started, the malfunction indicator lamp
should go off.
If the lamp remains on, the on board diagnostic system has
detected an engine system malfunction.
If MIL illuminates or blinks irregularly after starting engine,
water may have accumulated in fuel ®lter. Drain water from
fuel ®lter.
ON BOARD DIAGNOSTIC SYSTEM FUNCTION
The on board diagnostic system has the following three functions.
1. BULB CHECK : This function checks the MIL bulb for damage (blown, open circuit,
etc.).
2. MALFUNCTION
WARNING: This is a usual driving condition. When a malfunction is detected, the
MIL will light up to inform the driver that a malfunction has been
detected.
3. SELF-DIAGNOSTIC
RESULTS: This function allows diagnostic trouble codes to be read.
Refer to ``HOW TO SWITCH DIAGNOSTIC TEST MODES'' on next page.

DIAGNOSTIC TEST MODE IÐBULB CHECK
In this mode, the MALFUNCTION INDICATOR LAMP on the instrument panel should stay ON. If it remains
OFF, check the bulb. Refer to EL section (``WARNING LAMPS AND CHIME'') or see EC-188.
DIAGNOSTIC TEST MODE IÐMALFUNCTION WARNING
MALFUNCTION
INDICATOR LAMPCondition
ONWhen the malfunction is detected or the ECM's CPU is malfunctioning. (Refer to ``MIL Illumination'' of the
``DIAGNOSTIC TROUBLE CODE INDEX'', EC-1.)
OFF No malfunction.
+These Diagnostic Trouble Code Numbers are clari®ed in Diagnostic Test Mode II (SELF-DIAGNOSTIC
RESULTS).
DIAGNOSTIC TEST MODE IIÐSELF-DIAGNOSTIC RESULTS
In this mode, a diagnostic trouble code is indicated by the number of blinks of the MALFUNCTION INDICA-
TOR LAMP as shown below.
Long (0.6 second) blinking indicates the number of ten digits, and short (0.3 second) blinking indicates the
number of single digits. For example, the malfunction indicator lamp blinks 4 times for 5 seconds (0.6 sec x
4 times) and then it blinks three times for about 1 second (0.3 sec x 3 times). This indicates the DTC ``43''
and refers to the malfunction of the accelerator position sensor circuit.
In this way, all the detected malfunctions are classi®ed by their diagnostic trouble code numbers. The DTC
``55'' refers to no malfunction. (See DIAGNOSTIC TROUBLE CODE INDEX, EC-1.)
HOW TO ERASE DIAGNOSTIC TEST MODE II (Self-diagnostic results)
The diagnostic trouble code can be erased from the backup memory in the ECM when the diagnostic test mode
is changed from Diagnostic Test Mode II to Diagnostic Test Mode I. (Refer to ``HOW TO SWITCH DIAGNOS-
TIC TEST MODES'' on previous page.)
+If the battery terminal is disconnected, the diagnostic trouble code will be lost from the backup
memory within 24 hours.
+Be careful not to erase the stored memory before starting trouble diagnoses.
+If the MIL blinks or ``NATS MALFUNCTION'' is displayed on
``SELF-DIAG RESULTS'' screen, perform self-diagnostic
results mode with CONSULT using NATS program card
(NATS-E940). Refer to EL section.
+Con®rm no self-diagnostic results of NATS is displayed
before touching ``ERASE'' in ``SELF-DIAG RESULTS'' mode
with CONSULT.
+When replacing ECM, initialisation of NATS V2.0 system
and registration of all NATS V2.0 ignition key IDs must be
carried out with CONSULT using NATS program card
(NATS-E940).
Therefore, be sure to receive all keys from vehicle owner.
Regarding the procedures of NATS initialisation and NATS
ignition key ID registration, refer to CONSULT operation
manual, NATS V2.0.
