Lock-up Applied

In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the
torque converter clutch solenoid and lock-up apply pressure is generated.
In this way, the torque converter clutch piston is pressed and coupled.
SMOOTH LOCK-UP CONTROL
When shifting from the lock-up released state to the lock-up applied state, the current output to the torque con-
verter clutch solenoid is controlled with the TCM. In this way, when shifting to the lock-up applied state, the
torque converter clutch is temporarily set to the half-clutched state to reduce the shock.
Half-clutched State

The current output from the TCM to the torque converter clutch solenoid is varied to gradually increase
the torque converter clutch solenoid pressure.
In this way, the lock-up apply pressure gradually rises and while the torque converter clutch piston is put
into half-clutched status, the torque converter clutch piston operating pressure is increased and the cou-
pling is completed smoothly.
Slip Lock-up Control

In the slip region, the torque converter clutch solenoid current is controlled with the TCM to put it into the
half-clutched state. This absorbs the engine torque fluctuation and lock-up operates from low speed.
This raises the fuel efficiency for 4th and 5th gears at both low speed and when the accelerator is
depressed slightly throttle opening.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AJS001BM
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
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 per-
formed by an authorized NISSAN/INFINITI 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 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)AJS0013V
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 REFRIGER-
ANT” 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) compo-
nents. 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 fol-
lowing 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 possi-
ble to minimize the entry of moisture into system.
–Only use the specified lubricant from a sealed container. Immediately reseal containers of lubri-
cant. 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 meet-
ing 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.
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.

General Refrigerant PrecautionsAJS0013W
WARNING:

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.

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-
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-
ant manufacturers.
Lubricant PrecautionsAJS0013X

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 con-
necting 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. With-
out 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 require-
ments 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. Addi-
tional 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.

BODY REPAIR
Revision: 2004 November2004 FX35/FX45
Corrosion ProtectionAIS0065Q
DESCRIPTION
To provide improved corrosion prevention, the following anti-corrosive measures have been implemented in
NISSAN production plants. When repairing or replacing body panels, it is necessary to use the same anti-cor-
rosive measures.
Anti-corrosive Precoated Steel (Galvannealed Steel)
To improve repairability and corrosion resistance, a new type of anti-
corrosive precoated steel sheet has been adopted replacing conven-
tional zinc-coated steel sheet.
Galvannealed steel is electroplated and heated to form Zinc-iron
alloy, which provides excellent and long term corrosion resistance
with cationic electrodeposition primer.
Nissan Genuine Service Parts are fabricated from galvannealed steel. Therefore, it is recommended that
GENUINE NISSAN PARTS or equivalent be used for panel replacement to maintain the anti-corrosive perfor-
mance built into the vehicle at the factory.
Phosphate Coating Treatment and Cationic Electrodeposition Primer
A phosphate coating treatment and a cationic electrodeposition primer, which provide excellent corrosion pro-
tection, are employed on all body components.
CAUTION:
Confine paint removal during welding operations to an absolute
minimum.
Nissan Genuine Service Parts are also treated in the same manner. Therefore, it is recommended that GENU-
INE NISSAN PARTS or equivalent be used for panel replacement to maintain anti-corrosive performance built
into the vehicle at the factory.
