ENGINE ASSEMBLY
Revision: 2004 November 2004 FX35/FX45

After disconnection, plug the opening on transmission side.
11. Remove front drive shaft (both side). Refer to FAX-12, "
FRONT DRIVE SHAFT" .
12. Remove front propeller shaft. Refer to PR-4, "
FRONT PROPELLER SHAFT" .
13. Remove three way catalyst (both bank). Refer to EM-178, "
EXHAUST MANIFOLD AND THREE WAY
CATALYST" .
Removal Work
1. Install engine slingers into front of left bank cylinder head and
front of right bank cylinder head.
2. Lift with hoist and secure engine in position.
3. Use manual lift table caddy (commercial service tool) or equivalently rigid tool such as transmission jack.
Securely support bottom of suspension member and transmission.
CAUTION:
Put a piece of wood or something similar as the supporting surface, secure a completely stable
condition.
4. Remove front suspension member mounting nuts with power tool. Refer to FSU-6, "
FRONT SUSPEN-
SION ASSEMBLY" .
5. Carefully lower jack, or raise lift to remove engine, transmission
front final drive and front suspension member assembly. When
performing work, observe the following caution:
CAUTION:

Confirm there is no interference with vehicle.

Make sure that all connection points have been discon-
nected.

Keep in mind the center of vehicle gravity changes. If
necessary, use jack(s) to support vehicle at rear jacking
point(s) to prevent it from falling it off the lift.
Separation Work
1. Change engine slinger installing to cylinder head (right bank).
NOTE:
In order to keep secure position when hoisting engine.
2. Remove engine mounting insulators (RH and LH) under side nut with power tool.
3. Lift with hoist and separate engine and transmission assembly from front suspension member.
CAUTION:

Before and during this lifting, always check if any harnesses are left connected.

Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
4. Remove alternator. Refer to SC-23, "
CHARGING SYSTEM" . Slinger bolts:
:33.4 N·m (3.4 kg-m, 25 ft-lb)

5. Remove starter motor. Refer to SC-10, "STARTING SYSTEM" .
6. Separate engine from transmission assembly. Refer to AT- 2 6 9 , "
Removal and Installation (AWD models)"
.
7. Remove front final drive from engine. Refer to FFD-10, "
FRONT FINAL DRIVE ASSEMBLY" .
8. Remove engine mounting insulators (RH and LH) and brackets (RH and LH) from engine with power tool.
9. Remove engine rear member and engine mounting insulator (rear) from transmission.
INSTALLATION
Note to the following, and install in the reverse order of removal.

Where positioning pin is used, be sure to securely insert it into the hole of mating part.

When installing engine mount brackets (RH and LH) to cylinder
block, tighten two upper bolts (shown as “A” in the figure) first.
Then tighten two lower bolts (shown as “B” in the figure).
INSPECTION AFTER INSTALLATION

Before starting engine, check the levels of engine coolant, engine oil and working fluid. If less than
required quantity, fill to the specified level.

Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of engine coolant, engine oil, working fluid,
fuel and exhaust gas.

Bleed air from passages in pipes and tubes of applicable lines, such as in cooling system.

After cooling down engine, again check amounts of engine coolant, engine oil and working fluid. Refill to
specified level, if necessary.

DISASSEMBLY
NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1. Remove engine assembly from vehicle, and separate front suspension member, transmission and front
final drive from engine. Refer to EM-236, "
ENGINE ASSEMBLY" .
2. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use widely use engine holding the surface, to which trans-
mission is installed.
a. Remove drive plate.

Holding ring gear with ring gear stopper (SST).

Loosen mounting bolts diagonally order.
CAUTION:

Do not disassemble drive plate.

Do not place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
b. Remove engine rear plate.
3. Lift engine with hoist to install it onto widely use engine stand.
CAUTION:
Use engine stand that has a load capacity [approximately 240kg (529 lb) or more] large enough for
supporting the engine weight.

If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the
potential risk of overturning stand.

FRONT FOG LAMP
Revision: 2004 November 2004 FX35/FX45

to ignition relay [located in IPDM E/R (intelligent power distribution module engine room)]

through 15A fuse [No. 1, located in fuse block (J/B)]

to BCM (body control module) terminal 38.
When the ignition switch is in ACC or ON position, power is supplied

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

to BCM (body control module) terminal 11.
Ground is supplied

to BCM (body control module) terminals 49 and 52

through grounds M35, M45 and M85

to IPDM E/R (intelligent power distribution module engine room) terminals 38 and 60

through grounds E21, E50 and E51.
Fog Lamp Operation
The fog lamp switch is built into the combination switch. The lighting switch must be in the 2ND position or
AUTO position (LOW beam is ON) and the fog lamp switch must be ON for fog lamp operation.
With the fog lamp switch in the ON position, the CPU of the IPDM E/R grounds the coil side of the fog lamp
relay. The fog lamp relay then directs power

through IPDM E/R terminal 37

to front fog lamp LH terminal 1

through IPDM E/R terminal 36

to front fog lamp RH terminal 1.
Ground is supplied

to front fog lamp LH terminal 2

through grounds E21, E50 and E51, and

to front fog lamp RH terminal 2

through grounds E21, E50 and E51.
With power and grounds supplied, the front fog lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), the fog lamp switch is ON, and the
ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the fog lamps (and headlamps) remain illuminated for 5 minutes, then the fog lamps (and
headlamps) are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionAKS007CJ
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 UnitAKS0080V

NOTE:
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found
damaged or if the auto belt tensioner reading (only for VK45DE engine) reaches the maximum limit.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.
