Checking for Refrigerant LeaksNJS000FE
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage may indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electrical leak detector or fluorescent dye leak
detector (SST: J-42220).
If dye is observed, confirm the leak with an electrical leak detector. It is possible a prior leak was repaired and
not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electrical leak detector, move the probe along the suspected
leak area at 1 to 2 inches per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electrical leak detector probe slower and closer to the suspected leak area will improve the
chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak DetectorNJS000FF
1. Check A/C system for leaks using the UV lamp and safety goggles (SST: J-42220) in a low sunlight area (area without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a
bright green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain open-
ing indicates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner (SST: J-43872) to prevent future misdiagnosis.
4. Perform a system performance check and verify the leak repair with an approved electrical leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.
Dye InjectionNJS000FG
(This procedure is only necessary when recharging the system or when the compressor has seized and was
replaced.)
1. Check A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.52 kg/cm
2 , 50 psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (SST: J-41459).
3. Connect the injector tool to the A/C low-pressure side service valve.
4. Start the engine and switch A/C ON.
5. When the A/C operating (compressor running), inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye through the low-pressure service valve using dye injector tool (SST: J-41459) (refer to the manufacture’s
operating instructions).
6. With the engine still running, disconnect the injector tool from the service valve. CAUTION:
Be careful the A/C system or replacing a component, pour the dye directly into the open system
connection and proceed with the service procedures.
7. Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the leak size, operating conditions and location of the leak, it may take from minutes to days for the dye to
penetrate a leak and become visible.
8. Attach a blue label as necessary.

CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette
smoke in the vicinity of the vehicle. Perform the leak test in calm area (low air/wind movement) so that the
leaking refrigerant is not dispersed.
1. Stop the engine.
2. Connect a suitable A/C manifold gauge set (SST: J-39183) to the A/C service valves.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.52 kg/cm
2 , 50 psi) above 16 °C (61 °F). If less
than specification, recover/evacuate and recharge the system with the specified amount of refrigerant.
NOTE:
At temperatures below 16 °C (61 °F), leaks may not be detected since the system may not reach 345 kPa
(3.52 kg/cm
2 , 50 psi).
4. Perform the leak test from the high-pressure side (compressor discharge a to evaporator inlet h) to the low-pressure side [evaporator drain hose i to shaft seal o (VK45DE) or n (VQ35DE)]. Refer to ATC-139,
"Components" . Perform a leak check for the following areas carefully. Clean the component to be
checked and move the leak detected probe completely around the connection/component.
Compressor
Check the fitting of high- and low-pressure flexible hoses, relief valve and shaft seal.
Condenser
Check the fitting of high-pressure flexible hose and pipe, refrigerant pressure sensor.
Liquid tank
Check the fitting of refrigerant connection.
Service valves
Check all around the service valves. Ensure service valve caps are secured on the service valves (to pre-
vent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe any residue from valves to prevent any
false readings by leak detector.
Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in the
cooling unit. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer’s recommended
procedure for actual wait time) before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with water
or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components. If no leaks are found, perform steps 7 - 10.
7. Start the engine.
8. Set the A/C control as follows;
a. A/C switch: ON
b. Mode door position: VENT (Ventilation)
c. Intake position: Recirculation
d. Temperature setting: Max. cold
e. Fan speed: High
9. Run engine at 1,500 rpm for at least 2 minutes.
10. Stop the engine and perform leak check again following steps 4 through 6 above.
Refrigerant leaks should be checked immediately after stopping
the engine. Begin with the leak detector at the compressor. The
pressure on the high-pressure side will gradually drop after
refrigerant circulation stops and pressure on the low-pressure
side will gradually rise, as shown in the graph. Some leaks are
more easily detected when pressure is high.

NAVIGATION SYSTEM
Revision: 2006 July 2007 FX35/FX45
NAVIGATION SYSTEM
Location Detection Principle
The navigation system periodically calculates the vehicle's current
position according to the following three signals:

Travel distance of the vehicle as determined by the vehicle
speed sensor

Turning angle of the vehicle as determined by the gyroscope
(angular velocity sensor)

Direction of vehicle travel as determined by the GPS antenna
(GPS information)
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the DVD-ROM,
which is stored in the DVD-ROM drive (map-matching), and indi-
cated on the screen as a current-location mark. More accurate data is judged and used by comparing vehicle
position detection results found by the GPS with the result by map-matching.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.

Travel distance
Travel distance calculations are based on the vehicle speed
sensor input signal. Therefore, the calculation may become
incorrect as the tires wear down. To prevent this, an automatic
distance correction function has been adopted.

Travel direction
Change in the travel direction of the vehicle is calculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). They have both advantages and disadvantages.
More accurate traveling direction is selected because priorities are set for the signals from these two
devices according to the situation.
SKIB1058E
SEL684V
Type Advantage Disadvantage
Gyroscope (angular velocity sen-
sor) Can detect the vehicle's turning angle quite
accurately. Direction errors may accumulate when vehicle is
driven for long distances without stopping.
GPS antenna (GPS information) Can detect the vehicle's travel direction
(North/South/East/West). Correct direction cannot be detected when vehi-
cle speed is low.

Component DescriptionNKS003K1
NAVI CONTROL UNIT

The gyro (angular speed sensor) and the DVD-ROM drive are
built-in units that control the navigation functions.

Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining this data with the data contained in the DVD-ROM map.
Locational information is shown on liquid crystal display panel.
DVD-ROM Drive
Maps, traffic control regulations, and other pertinent information can
be easily read from the DVD-ROM.
DVD-ROM

The DVD-ROM has maps, traffic control regulations, and other pertinent information.

To improve DVD-ROM map matching and route determination functions, the DVD-ROM uses an exclusive
Nissan format. Therefore, the use of a DVD-ROM provided by other manufacturers cannot be used.
Gyro (Angular Speed Sensor)

The oscillator gyro sensor is used to detect changes in vehicle steering angle.

The gyro is built into the navigation (NAVI) control unit.
GPS ANTENNA
The GPS antenna receives and amplifies the radio waves from the GPS satellites, and then transmits the GPS
signal to NAVI control unit.
DISPLAY CONTROL UNIT

Display control unit draws a status of the audio and air condi-
tioner, a TRIP screen, a FUEL ECONOMY screen, etc., and
transmits the image signals to the display screen.

It receives operation signals of audio and air conditioner from A/
C and AV switch, and transmits the operation signal of audio to
the audio unit via the communication line and transmits the
operation signal of air conditioner to the meter and A/C amp. via
CAN communication.

ROUTE CALCULATION AND VISUAL GUIDANCE
The GPS indicator on the screen
remains gray. GPS signals cannot be received depending on
the vehicle location, such as in a parking
garage, on a road that has numerous tall build-
ings, etc. Drive on an open, straight road for a while.
A sufficient amount of GPS satellites is not
available. Please wait for the satellites to move to loca-
tions available for the navigation system.
The location of the vehicle mark is
misaligned from the actual posi-
tion. When using tire chains or replacing the tires,
speed calculations based on the speed sensor
may be incorrect. Drive the vehicle for a while [at approximately
30 km/h (19 MPH) for about 30 minutes] to
automatically correct the vehicle's mark posi-
tion. If this does not correct the vehicle mark
position, contact a NISSAN dealer or qualified
workshop.
The map data has a mistake or is incomplete
(the vehicle mark position is always misaligned
in the same area). Updated road information will be included in
the next version of the DVD-ROM.
Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The message “Error” appears. The DVD-ROM is dirty or partially damaged. Check the DVD-ROM and wipe it clean with a
soft cloth.
If any damage, replace the DVD-ROM.
Symptom Possible cause Possible solution
In the auto re-route calculation,
waypoints are not included. Waypoints that you have already passed are
not included in the auto re-route calculation. To go to that waypoint again, it is necessary to
edit the route.
Route information is not dis-
played. Route calculation has not yet been performed.
Set the destination and perform route calcula-
tion.
Vehicle is not driving on the suggested route. Drive on the suggested route.
Route guidance is set to off. Turn on the route guidance.
The auto re-route calculation (or
detour calculation) suggests the
same route as the one previously
suggested. Route calculations took priority conditions into
consideration, but the same route was calcu-
lated. This is not a malfunction.
A waypoint cannot be added. Five waypoints are already set on the route,
including the ones that you have already
passed. A maximum of 5 waypoints can be set on the
route. If you want to go to 6 or more waypoints,
perform route calculations several times, as
necessary.
The suggested route is not dis-
played. Roads near the destination cannot be calcu-
lated. Reset the destination to a main or ordinary
road, and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far
away. Divide your trip by selecting one or two inter-
mediate destinations, and perform a global
route calculation based on multiple route cal-
culations.
There are time restricted roads (day of week,
time) near the current vehicle location or desti-
nation. Set [Use Time Restricted Roads] to off.
The part of the route already
passed is deleted. A route is managed by sections between way-
points. If passing the first waypoint, the section
between the starting point and the waypoint is
deleted. (It may not be deleted depending on
the area.) This is not a malfunction.
