Removal and Installation of Liquid TankAJS0015Y
REMOVAL
1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2. Remove front grille. Refer to EI-23, "
FRONT GRILLE" .
3. Clean liquid tank and its surrounding area, and remove dirt and rust from tank.
CAUTION:
Be sure to clean carefully.
4. Remove mounting bolts for liquid tank and power steering oil cooler.
5. Lift liquid tank upwards. Remove bracket from protruding part of
condenser.
6. Slide liquid tank upward, and then remove liquid tank.
INSTALLATION
Install liquid tank, and then install liquid tank bracket on condenser.
CAUTION:

Make sure liquid tank bracket is securely installed at protru-
sion of condenser. (Make sure liquid tank bracket does not
move to a position below center of liquid tank.)

Replace O-rings for A/C piping with new ones, then apply
compressor oil to it when installing it.

When recharging refrigerant, check for leaks.Bolts mounting low-pressure pipe 1 bracket and low-pressure flexible hose bracket

Removal and Installation of CondenserAJS0015Z
REMOVAL
1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2. Remove the air cleaner and air duct. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" (VQ35DE) or EM-
172, "AIR CLEANER AND AIR DUCT" (VK45DE).
3. Remove engine undercover, using power tools.
4. Drain engine coolant (VK45DE). Refer to CO-36, "
Changing Engine Coolant" .
5. Remove cooling fan shroud after removing radiator upper hose (VK45DE). Refer to CO-39, "
RADIATOR" .
6. Remove mounting bolt for high-pressure flexible hose bracket.
7. Disconnect high-pressure flexible hose and high-pressure pipe
1 from condenser.
a. Set a disconnector (Condenser outlet: 92530-89908, Condenser
inlet: 92530-89912) on A/C piping.
b. Slide a disconnector upward until it clicks.
c. Slide A/C piping upward and disconnect it.
CAUTION:
Cap or wrap the joint of the pipe with suitable material such
as vinyl tape to avoid the entry of air.
8. Remove mounting bolts for condenser.
9. Remove radiator upper mount, move radiator and condenser to the engine side.
10. Remove condenser.
CAUTION:
Be careful not to damage the core surface of the condenser and the radiator.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace O-rings for A/C piping with new ones, then apply compressor oil to it when installing it.

Connection point for female-side piping is thin. So, when inserting male-side piping, take care not
to deform female-side piping. Slowly insert in axial direction.

Insert one-touch joint connection point securely until it clicks.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS007X5
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.
Wiring Diagrams and Trouble DiagnosisAKS007X6
When reading wiring diagrams, refer to the following:

Refer to GI-15, "How to Read Wiring Diagrams" .
Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
When performing trouble diagnosis, refer to the following:

Refer to GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" .
Refer to GI-27, "
How to Perform Efficient Diagnosis for an Electrical Incident" .

System DescriptionAKS00BMM
BASE SYSTEM
Refer to Owner's Manual for audio system operating instructions.
Power is supplied at all times

through 15A fuse (No. 32, located in the fuse and fusible link block)

to audio unit terminal 6

to A/C and AV switch terminal 1 and

to display control unit terminal 1 (with navigation system) or display unit terminal 1 (without navigation sys-
tem).
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)]

to audio unit terminal 10

to A/C and AV switch terminal 2 and

to display control unit terminal 10 (with navigation system) or display unit terminal 2 (without navigation
system).
Ground is supplied through the case of the audio unit.
Ground is also supplied

to A/C and AV switch terminal 5

to display control unit terminal 3 and 13 (with navigation system)

to display terminal 1 (with navigation system)

to display unit terminal 6 and 15 (without navigation system)

through body ground M35, M45 and M85

to option connector for satellite radio receiver terminal 10

through body ground B210 and B203.
Audio unit, A/C and audio controller are connected by FPC (Flexible Print Circuit).
A/C and audio controller integrates A/C switches and audio switches.
When A/C and audio controller is pushed to audio switch, it sends audio signal to audio unit.
Then audio signals are supplied

through audio unit terminals 1, 2, 3, 4, 13, 14, 15, and 16

to terminals 1 and 2 of front door speaker LH and RH

to terminals 1 and 2 of rear door speaker LH and RH

to terminals 1 and 2 of instrument speaker LH and RH.
When one of audio steering wheel switch is pushed to volume up, seek up, or mode ON, resistance in steering
switch circuit changes depending on which button is pushed.
When one of audio steering wheel switch is pushed to volume down, seek down, or power ON, resistance in
audio steering wheel switch circuit changes depending on which button is pushed.
BOSE SYSTEM
Refer to Owner's Manual for audio system operating instructions.
Power is supplied at all times

through 15A fuse (No. 32, located in the fuse and fusible link block)

to audio unit terminal 6

to woofer terminal 1

to A/C and AV switch terminal 1 and

to display control unit terminal 1 (with navigation system) or display unit terminal 1 (without navigation sys-
tem),

through 20A fuse [No.17, located in the fuse block (J/B)]

to BOSE speaker amp. terminal 1.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)]

to audio unit terminal 10
