CAUTION:

When removing water pump, be careful not to get engine coolant on drive belt.

Water pump can not be disassembled and should be replaced as a unit.
REMOVAL
1. Drain engine coolant from drain plugs on radiator and both side of cylinder block. Refer to CO-36, "Chang-
ing Engine Coolant" and EM-241, "DISASSEMBLY" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
2. Remove following parts:

Engine front undercover

Air duct (inlet); Refer to EM-172, "AIR CLEANER AND AIR DUCT" .

Alternator, water pump and A/C compressor belt; Refer to EM-169, "DRIVE BELTS" .
3. Remove fan coupling with cooling fan, and then water pump pulley.
4. Remove water pump.

Engine coolant will leak from the cylinder block, so have a receptacle ready under vehicle.
CAUTION:

Handle the water pump vane so that it does not contact any other parts.

Do not disassemble water pump.
INSPECTION AFTER REMOVAL

Visually check that there is no significant dirt or rusting on water
pump body and vane.

Make sure there is no looseness in vane shaft, and that it turns
smoothly when rotated by hand.

If anything is found, replace water pump.

PRECAUTION PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS0054B
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 Diagnosis AKS0054D
When you read wiring diagrams, refer to the following:

Refer to GI-15, "How to Read Wiring Diagrams" .

Refer toPG-3, "POWER SUPPLY ROUTING CIRCUIT" for power distribution circuit.
When you perform 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" .

UNIFIED METER AND A/C AMP
Revision: 2004 November 2004 FX35/FX45
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionAKS005N8

For the unified meter and A/C amp., the signal required for controlling the combination meter are inte-
grated in the A/C auto amp.

Unified meter and A/C amp. controls each operation for A/C auto amp. For information regarding A/C con-
trol, refer to AT C - 3 0 , "
AIR CONDITIONER CONTROL" in ATC section.

Unified meter and A/C amp. inputs necessary information for combination meter from each unit by CAN
communication and so on.

And unified meter and A/C amp. outputs these signals using communication line (TX, RX) between unified
meter and A/C amp. and combination meter.

The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (without NAVI) display control unit (with NAVI) using
CAN communication.

Other input signals are also sent to the ECM, TCM, AWD control unit, BCM, display unit (without NAVI)
and display control unit (with NAVI) using CAN communication.

The unified meter and A/C amp. have a CONSULT-II function (self-diagnostic results, CAN diagnostic
support monitor, data monitor).

CAN Communication System DescriptionAKS007Z2
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAKS007YY
