INSUFFICIENT COOLING
Low-pressure Side Becomes Negative
Gauge indication Refrigerant cycle Probable cause Corrective action
Low-pressure side sometimes be-
comes negative. Air conditioning system does
not function and does not cy-
clically cool the compart-
ment air.
 The system constantly func-
tions for a certain period of
time after compressor is
stopped and restarted.Refrigerant does not discharge
cyclically.
↓
Moisture is frozen at expan-
sion valve outlet and inlet.
↓
Water is mixed with refrigerant. Drain water from refrigerant
or replace refrigerant.
 Replace liquid tank.
AC354A
Gauge indication Refrigerant cycle Probable cause Corrective action
Low-pressure side becomes nega-
tive.
Liquid tank or front/rear side of
expansion valve’s pipe is frost-
ed or dewed.High-pressure side is closed
and refrigerant does not flow.
↓
Expansion valve or liquid tank
is frosted.Leave the system at rest until
no frost is present. Start it
again to check whether or not
the malfunction is caused by
water or foreign particles.
 If water is the cause, initially
cooling is okay. Then the wa-
ter freezes causing a block-
age. Drain water from
refrigerant or replace refrig-
erant.
 If due to foreign particles, re-
move expansion valve and
remove the particles with dry
and compressed air (not
shop air).
 If either of the above meth-
ods cannot correct the mal-
function, replace expansion
valve.
 Replace liquid tank.
 Check oil for contamination.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001548120
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 har-
ness connectors.
Precaution for Procedures Without Cowl Top CoverINFOID:0000000001548121
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Working with HFC-134a (R-134a)INFOID:0000000001547383
WARNING:
 CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants
are mixed compressor failure is likely to occur. Refer to XX-XX, "*****"
. 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 oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If
oil other than that specified is used, compressor failure is likely to occur.
 The specified HFC-134a (R-134a) oil 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 oil from a sealed container. Immediately reseal containers of oil. Without
proper sealing, oil will become moisture saturated and should not be used.
- Avoid breathing A/C refrigerant and oil 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 J2210 [HFC-134a (R-134a) recycling equipment], or J2209 [HFC-134a (R-134a) recy-
cling equipment], If accidental system discharge occurs, ventilate work area before resuming
service. Additional health and safety information may be obtained from refrigerant and oil manufac-
turers.

HAC-314
< PRECAUTION >[AUTO AIR CONDITIONER (W/NAVI)]
PRECAUTIONS
- Do not allow A/C oil 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 refrigerant
supply.
 Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
 If you choose to perform the repair, recover the refrigerant using only dedicated equipment and contain-
ers. 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 ser-
vice. 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 Cus-
tomer Affairs for further assistance.
Precaution for Service EquipmentINFOID:0000000001547384
MANIFOLD GAUGE SET
Be certain that the gauge face indicates R-134a or 134a. Make 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) along with specified oil.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off 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.

ILLUMINATION CONTROL SYSTEM
ILLUMINATION CONTROL SYSTEM
System DiagramINFOID:0000000001730918
System DescriptionINFOID:0000000001730919
The illumination lamps operation is dependent upon the position of the lighting switch (combination switch).
When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated) the BCM
(body control module) receives input requesting the parking lamps to illuminate. This input is communicated to
the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU
(central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized, this relay directs
power to the parking and illumination lamps, which then illuminate.
BATTERY SAVER CONTROL
When the lighting switch (combination switch) is in the 1ST or 2ND position and the ignition switch is turned
from ON or ACC to OFF, the battery saver control feature is activated. Under this condition, the illumination
lamps remain illuminated for 30 minutes unless the lighting switch position is changed. If the lighting switch
position is changed, then the illumination lamps are turned off after a 30 second delay. When the lighting
switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after illumination lamps
have been turned off by the battery saver control, the illumination lamps illuminate again.
