Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” AJS001OL

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. Information necessary to service the system safely is included in the SRS and SB section of 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 inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.

●Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section.

●Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

Precautions for Working with HFC-134a (R-134a)

AJS001OI

WARNING:

●CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants are mixed and compressor malfunction is likely to occur, refer to “CONTAMINATED REFRIGERANT” below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refrigerant Recovery/Recycling Recharging equipment and Refrigerant identifier.

●Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If lubricant other than that specified is used, compressor malfunction is likely to occur.

●The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The following handling precautions must be observed:

–When removing refrigerant components from a vehicle, immediately cap (seal) the component to minimize the entry of moisture from the atmosphere.

–When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just before connecting the components. Connect all refrigerant loop components as quickly as possible to minimize the entry of moisture into system.

–Only use the specified lubricant from a sealed container. Immediately reseal containers of lubricant. Without proper sealing, lubricant will become moisture saturated and should not be used.

–Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meeting requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (R- 134a) recovery equipment]. If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and lubricant manufacturers.

–Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam parts. Damage may result.

PRECAUTIONS

CONTAMINATED REFRIGERANT

If a refrigerant other than pure HFC-134a (R-134a) is identified in a vehicle, your options are:

●Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into the atmosphere.

●	Explain that recovery of the contaminated refrigerant could damage your service equipment and refriger-
	ant supply.
●	Suggest the customer return the vehicle to the location of previous service where the contamination may
	have occurred.

A

B

C

●If you choose to perform the repair, recover the refrigerant using only dedicated equipment and containers. Do not recover contaminated refrigerant into your existing service equipment. If your facility

does not have dedicated recovery equipment, you may contact a local refrigerant product retailer for available service. This refrigerant must be disposed of in accordance with all federal and local regulations. In addition, replacement of all refrigerant system components on the vehicle is recommended.

●If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact Nissan Customer Affairs for further assistance.

General Refrigerant Precautions

AJS001JW

WARNING:

D

E

F

●Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the refrigerant every time an air conditioning system is discharged.

●Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air conditioning system.

●Do not store or heat refrigerant containers above 52° C (125° F).

●Do not heat a refrigerant container with an open flame; if container warming is required, place the bottom of the container in a warm pail of water.

●Do not intentionally drop, puncture, or incinerate refrigerant containers.

●Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.

G

H

I

●Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent suffocation.

●Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condi- ATC tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a) have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause

injury or property damage. Additional health and safety information may be obtained from refriger- K ant manufacturers.

Lubricant Precautions

AJS001JX

●Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If lubricant other than that specified is used, compressor malfunction is likely to occur.

●The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The following handling precautions must be observed:

–When removing refrigerant components from a vehicle, immediately cap (seal) the component to minimize the entry of moisture from the atmosphere.

–When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just before connecting the components. Connect all refrigerant loop components as quickly as possible to minimize the entry of moisture into system.

–Only use the specified lubricant from a sealed container. Immediately reseal containers of lubricant. Without proper sealing, lubricant will become moisture saturated and should not be used.

●Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meeting requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (R-134a) recovery equipment]. If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and lubricant manufacturers.

●Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam parts. Damage may result.

PRECAUTIONS

Precautions for Refrigerant Connection

AJS001JY

A new type refrigerant connection has been introduced to all refrigerant lines except the following location.

●Expansion valve to cooling unit

●Refrigerant pressure sensor to liquid tank

FEATURES OF NEW TYPE REFRIGERANT CONNECTION

●The O-ring has been relocated. It has also been provided with a groove for proper installation. This eliminates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of the O-ring is now set vertically in relation to the contacting surface of the mating part to improve sealing characteristics.

●The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facilitating piping connections.

Revision: 2005 March

ATC-7

2005 X-Trail

PRECAUTIONS

●When the compressor is removed, store it in the same position as it is when mounted on the car. Malfunction to do so will cause lubricant to enter the low-pressure chamber.

●When connecting tubes, always use a torque wrench and a back-up wrench.

●After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.

●When installing an air conditioner in the vehicle, connect the pipes as the final stage of the operation. Do not remove the seal caps of pipes and other components until just before required for connection.

●Allow components stored in cool areas to warm to working area temperature before removing seal caps. This prevents condensation from forming inside A/C components.

●Thoroughly remove moisture from the refrigeration system before charging the refrigerant.

●Always replace used O-rings.

●When connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not to apply lubricant to threaded portion.

Lubricant name	: Nissan A/C System Oil Type S
Part number	: KLH00-PAGS0

●O-ring must be closely attached to dented portion of tube.

●When replacing the O-ring, be careful not to damage O-ring and tube.

●Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that the O-ring is installed to tube correctly.

●After connecting line, conduct leak test and make sure that there is no leakage from connections. When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten connections of seal seat to the specified torque.

PRECAUTIONS

Precautions for Servicing Compressor

AJS001JZ

●Plug all openings to prevent moisture and foreign matter from entering.

●When the compressor is removed, store it in the same position as it is when mounted on the car.

●When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compressor” exactly. Refer to ATC-22, "Maintenance of Lubricant Quantity in Compressor" .

●Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with lubricant, wipe it off by using a clean waste cloth moistened with thinner.

●After compressor service operation, turn the compressor shaft by hand more than five turns in both directions. This will equally distribute lubricant inside the compressor. After the compressor is installed, let the engine idle and operate the compressor for one hour.

●After replacing the compressor magnet clutch, apply voltage to the new one and check for usual operation.

Precautions for Service Equipment

AJS001K0

RECOVERY/RECYCLING EQUIPMENT

Be certain to follow the manufacturer’s instructions for machine operation and machine maintenance. Never introduce any refrigerant other than that specified into the machine.

ELECTRONIC LEAK DETECTOR

Be certain to follow the manufacturer’s instructions for tester operation and tester maintenance.

VACUUM PUMP

The lubricant contained inside the vacuum pump is not compatible with the specified lubricant for HFC-134a (R-134a) A/C systems. The vent side of the vacuum pump is exposed to atmospheric pressure. So the vacuum pump lubricant may migrate out of the pump into the service hose. This is possible when the pump is switched off after evacuation (vacuuming) and hose is connected to it.

To prevent this migration, use a manual valve placed near the hose- to-pump connection, as follows.

●Usually vacuum pumps have a manual isolator valve as part of the pump. Close this valve to isolate the service hose from the pump.

●For pumps without an isolator, use a hose equipped with a manual shut-off valve near the pump end. Close the valve to isolate the hose from the pump.

●If the hose has an automatic shut-off valve, disconnect the hose from the pump. As long as the hose is connected, the valve is open and lubricating oil may migrate.

Some one-way valves open when vacuum is applied and close under a no vacuum condition. Such valves may restrict the pump’s ability to pull a deep vacuum and are not recommended.

RHA270DA

MANIFOLD GAUGE SET

Be certain that the gauge face indicates HFC-134a or R-134a. Be sure the gauge set has 1/2″ -16 ACME threaded connections for service hoses. Confirm the set has been used only with refrigerant HFC-134a (R-134a) and specified lubricants.

PRECAUTIONS

SERVICE HOSES

Be certain that the service hoses display the markings described (colored hose with black stripe). All hoses must include positive shutoff devices (either manual or automatic) near the end of the hoses opposite the manifold gauge.

SERVICE COUPLERS

Never attempt to connect HFC-134a (R-134a) service couplers to a CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will not properly connect to the CFC-12 (R-12) system. However, if an improper connection is attempted, discharging and contamination may occur.

REFRIGERANT WEIGHT SCALE

Verify that no refrigerant other than HFC-134a (R-134a) and specified lubricants have been used with the scale. If the scale controls refrigerant flow electronically, the hose fitting must be 1/2″ -16 ACME.

RHA272D

RHA273D

RHA274D

CHARGING CYLINDER

Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an electronic scale or of quality recycle/recharge equipment.

Precautions for Leak Detection Dye

AJS001K1

●The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet (UV) lamp is required to illuminate the dye when inspecting for leaks.

●Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of the fluorescent dye.

●The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluorescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to (J- 41995) pin-point refrigerant leaks.

●For your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions and precautions prior to performing the work.

●A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal should only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995).

●Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis during a future service.

Revision: 2005 March

ATC-10

2005 X-Trail

PRECAUTIONS

●Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled,

clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period of time cannot be removed.

●Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).

REFRIGERATION SYSTEM

REFRIGERATION SYSTEM

Refrigerant Cycle

REFRIGERANT FLOW

PFP:KA990

AJS001K5

The refrigerant flows in the standard pattern, that is, through the compressor, the condenser with liquid tank, through the evaporator, and back to the compressor. The refrigerant evaporation through the evaporator is controlled by an externally equalized expansion valve, located inside the evaporator case.

FREEZE PROTECTION

Under usual operating conditions, when the A/C is switched on, the compressor runs continuously, and the evaporator pressure, and therefore, temperature is controlled by the V-6 variable displacement compressor to prevent freeze up.

Refrigerant System Protection

AJS001K6

REFRIGERANT PRESSURE SENSOR

The refrigerant system is protected against excessively highor low-pressures by the refrigerant pressure sensor, located on the liquid tank. If the system pressure rises above, or falls below the specifications, the refrigerant pressure sensor detects the pressure inside the refrigerant line and sends the voltage signal to the ECM. ECM makes the A/C relay go OFF and stops the compressor when pressure on the high-pressure side

detected by refrigerant pressure sensor is over about 2,746 kPa (28 kg/cm2 , 398 psi), or below about 134 kPa (1.4 kg/cm2 , 20 psi).

PRESSURE RELIEF VALVE

The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.

When the pressure of refrigerant in the system increases to an unusual level [more than 3,727 kPa (38 kg/cm2 , 540 psi)], the release port on the pressure relief valve automatically opens and releases refrigerant into the atmosphere.

REFRIGERATION SYSTEM

V-6 Variable Displacement Compressor	AJS001K7
GENERAL INFORMATION	A

1.The V-6 variable compressor differs from previous units. The vent temperatures of the V-6 variable com-

	pressor do not drop too far below 5° C (41° F) when:
	Evaporator intake air temperature is less than 20° C (68° F).	B
	Engine is running at speeds less than 1,500 rpm.
	This is because the V-6 compressor provides a means of “capacity” control.
	2. The V-6 variable compressor provides refrigerant control under varying conditions. During cold winters, it	C
	may not produce high refrigerant pressure discharge (compared to previous units) when used with air
	conditioning systems.

3.A “clanking” sound may occasionally be heard during refrigerant charge. The sound indicates that the tilt D angle of the wobble (swash) plate has changed and is not a malfunction.

4.For air conditioning systems with the V-6 compressor, the clutch remains engaged unless: the system

main switch, fan switch or ignition switch is turned OFF. When ambient (outside) temperatures are low or	E
when the amount of refrigerant is insufficient, the clutch is disengaged to protect the compressor.

5.A constant range of suction pressure is maintained when engine speed is greater than a certain value. It

normally ranges from 147 to 177 kPa (1.5 to 1.8 kg/cm2 , 21 to 26 psi) under varying conditions.	F
In previous compressors, however, suction pressure was reduced with increases in engine speed.

REFRIGERATION SYSTEM

DESCRIPTION General

The variable compressor is basically a swash plate type that changes piston stroke in response to the required cooling capacity.

The tilt of the wobble (swash) plate allows the piston’s stroke to change so that refrigerant discharge can be continuously changed from 13.5 to 146 cm3 (0.824 to 8.91 cu in).

SJIA0631E

Revision: 2005 March

ATC-18

2005 X-Trail

REFRIGERATION SYSTEM

Operation

1.Operation Control Valve

Operation control valve is located in the suction port (low-pressure) side, and opens or closes in response to changes in refrigerant suction pressure.

Operation of the valve controls the internal pressure of the crankcase.

The angle of the wobble (swash) plate is controlled between the crankcase’s internal pressure and the piston cylinder pressure.

2.Maximum Cooling

Refrigerant pressure on the low-pressure side increases with an increase in heat loads.

When this occurs, the control valve’s bellows compress to open the low-pressure side valve and close the high-pressure side valve.

This causes the following pressure changes:

●The crankcase’s internal pressure to equal the pressure on the low-pressure side;

●The cylinder’s internal pressure to be greater than the crankcase’s internal pressure.

Under this condition, the wobble (swash) plate is set to the maximum stroke position.

RHA473C

3.Capacity Control

●Refrigerant pressure on suction side is low during high speed driving or when ambient or interior temperature is low.

●The bellows expands when refrigerant pressure on the suction pressure side drops below approxi mately 177 kPa (1.8 kg/cm2 , 26 psi).

Since suction pressure is low, it makes the suction port close and the discharge port open. Thus, crankcase pressure becomes high as high-pressure enters the crankcase.

●The force acts around the journal pin near the wobble (swash) plate, and is generated by the pressure difference between before and behind the piston.

The drive lug and journal pin are located where the piston generates the highest pressure. Piston pressure is between suction pressure Ps and discharge pressure Pd, which is near suction pressure Ps. If crankcase pressure Pc rises due to capacity control, the force around the journal pin makes the wobble (swash) plate angle decrease and also the piston stroke decrease. In other words, crankcase pressure increase triggers pressure difference between the piston and the crankcase. The pressure difference changes the angle of the wobble (swash) plate.

System Construction

AJS001KB

A small network is constructed between the auto amp., air mix door motor, mode door motor and intake door motor. The auto amp. and motors are connected by data transmission lines and motor power supply lines. The LAN network is built through the ground circuits of each door motor.

Addresses, motor opening angle signals, motor stop signals and error checking messages are all transmitted through the data transmission lines connecting the auto amp. and each door motor.

The following functions are contained in LCUs built into air mix door motor, mode door motor and intake door motor.

●Address

●Motor opening angle signal

●Data transmission

●Motor stop and drive decision

●Opening angle sensor (PBR function)

●Comparison

●Decision (Auto amp. indicated value and motor opening angle comparison)

RHA350H

OPERATION

The auto amp. receives data from each of the sensors. The auto amp. sends mode door, air mix door and intake door opening angle data to the mode door motor LCU, air mix door motor LCU and intake door motor LCU.

The mode door motor, air mix door motor and intake door motor read their respective signals according to the address signal. Opening angle indication signals received from the auto amp. and each of the motor position sensors is compared by the LCUs in each motor with the existing decision and opening angles. Subsequently, HOT/COLD, DEF/VENT or FRESH/RECIRCULATION operation is selected. The new selection data is returned to the auto amp.

TRANSMISSION DATA AND TRANSMISSION ORDER

Auto amp. data is transmitted consecutively to each of the door motors following the form shown in figure below.

Start:

Initial compulsory signal sent to each of the door motors.

Address:

Data sent from the auto amp. is selected according to data-based decisions made by the air mix door motor, mode door motor and intake door motor.

If the addresses are identical, the opening angle data and error check signals are received by the door motor LCUs. The LCUs then make the appropriate error decision. If the opening angle data is usual, door control begins.

If an error exists, the received data is rejected and corrected data received. Finally, door control is based upon the corrected opening angle data.

Opening Angle:

Data that shows the indicated door opening angle of each door motor.

Error Check:

Procedure by which sent and received data is checked for errors. Error data is then compiled. The error check prevents corrupted data from being used by the air mix door motor, mode door motor and intake door motor. Error data can be related to the following symptoms.

●Malfunction electrical frequency

●Poor electrical connections

●Signal leakage from transmission lines

●Signal level fluctuation
