Checking Fluid LevelEGS0004B
lCheck the fluid level with the engine OFF.
lCheck that fluid level is between MAX and MIN marks on tank.
Fluid level should not exceed MAX mark. Excessive fluid will
cause fluid to leak from cap.
lNote that fluid level can change depending on temperature of
fluid. HIGH and LOW marks are shown on tank to indicate the
proper level at high temperature and low temperature respec-
tively.
CAUTION:
lNever reuse drained power steering fluid.
lUse DEXRONTMIII or equivalent. Never use Nissan Power Steering Fluid Special, Nissan Matic
Fluid C, or D.
Checking Fluid LeakEGS0004C
Check hydraulic connections for any leak, crack, damage, loose-
ness, or wear.
1. Run engine until fluid temperature reaches 50 to 80°C (122 to
176°F) in reservoir tank. Keep engine speed at idle.
2. Turn steering wheel several times from stop to stop.
3. Turn the steering wheel clockwise or counter clockwise until it
reaches the stop and hold it for five seconds. Check for fluid
leak.
CAUTION:
Do not hold steering wheel at stop for 15 seconds or longer.
Otherwise, pump may be damaged.
4. If any leak is found on joint, loosen and retighten flair nut. Excessive tightening may damage O-ring,
washer, or connector.
Bleeding Hydraulic SystemEGS0004D
1. Lift vehicle.
2. Fill tank up to MAX mark. Turn steering wheel several times from stop to stop. Add fluid if fluid level goes
down. Repeat this step until there is no fluid decrease and no bubble in tank.
3. Start engine and repeat step above with engine at idle. Continue step until no decrease in fluid happens.
If bleeding is not complete, following symptoms can be observed.
lBubbles are created in reservoir tank.
lRattling noise can be heard from oil pump.
lWhiningnoisecanbeheardfromoilpump.
Turn steering wheel slowly or stop vehicle. Sound of fluid movement may be heard from gear valve and
pump. This sound has nothing to do with steering performance or durability.HOT : Oil temperature 50 to 80°C (122 to 176°F)
COLD : Oil temperature 0 to 30°C(32to86°F)

CautionEDS00056
lBefore starting diagnosis of the vehicle, understand symptoms well. Perform correct and systematic oper-
ations.
lCheck for the correct installation status prior to removal or disassembly. When mating marks are required,
be sure they do not interfere with the function of the parts they are applied to.
lCarry out an overhaul in a clean work place. Using a dust proof room is recommended.
lBefore disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
lCheck appearance of the disassembled parts for damage, deformation, and abnormal wear. If a malfunc-
tion is detected, replace it with a new one.
lNormally replace lock pins, oil seals, and bearings with new ones every time they are removed.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
lClean and flush the parts sufficiently and blow them dry.
lBe careful not to damage the sliding surfaces and mating surfaces.
lWhen applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
lAlways use shop paper for cleaning the inside of components.
lAvoid using cotton gloves or a shop cloth to prevent entering of lint.
lDuring assembly, observe the specified tightening torque, and apply new differential oil, Vaseline, or Nis-
san MP Special Grease No. 2, as specified for each vehicle, when necessary.
lDo not reuse drained oil. Discard waste oil after oil changes or part treatment in accordance with local
laws and regulations.
Precautions for Brake SystemEDS000HX
lWhen installing rubber parts, final tightening must be carried out
under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
lAfter installing removed suspension parts, check wheel align-
ment and adjust if necessary.
lUse flare nut wrench when removing or installing brake tubes.
lAlways torque brake lines when installing.

System ComponentEDS000IJ
System DescriptionEDS000IK
ERECTRONIC COUPLING
lIn response to command current from 4WD control unit, control
clutch pull-in force is generated at the electromagnet and torque
is generated at the control clutch.
lThe cam operates in response to control clutch torque and
applies pressure to main clutch.
lMain clutch transmits torque from input shaft to output shaft,
according to the amount of pressure.
lThe actual amount of torque transfer is determined by control
current as shown in figure below (I-T characteristics figure).
4WD CONTROL UNIT
lControls distribution of drive power between front-wheel drive
(100:0) and 4WD (50:50) conditions circuit according to signals
from sensors.
lIf malfunction occurs in 4WD system, 4WD warning lamp turns
ON and vehicle changes to front-wheel drive.
lSelf-diagnosis can be done with CONSULT-II.

ALL MODE 4X4 SYSTEM
4WD MODE SWITCT
AUTO mode (AUTO indicator lamp ON)
lElectronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
lMakes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
lOn roads which do not require 4WD, it contributes to improved fuel economy by driving in conditions close
to front-wheel drive.
lSensors determine the vehicle's turning condition, and in response tight cornering/braking are controlled
by distributing optimum torque to rear wheels.
NOTE:
lWhen driving in AUTO mode or LOCK mode, if there is a large difference between front and rear wheel
speed which continues for a long time, oil temperature of drive system parts becomes too high and 4WD
warning lamp flashes rapidly. (When 4WD warning lamp flashes, vehicle changes to front-wheel drive
conditions.)
lWhen driving in AUTO mode, 4WD warning lamp may flash slowly if there is a significant difference in
pressure or wear between tires. At this time, vehicle performance is not fully available and cautious driving
is required. (Continues until engine is turned OFF.)
lIf 4WD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop
and AUTO mode will be restored.
lIf the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is
normal. If it again flashes slowly after driving for some time, vehicle must be inspected.
lWhen the difference of revolution speed between the front and rear wheel with AUTO mode the shift
switch occasionally changes to LOCK mode automatically. This is not malfunction.
LOCK mode (LOCK indicator lamp and AUTO indicator lamp ON)
lFront/rear wheel torque distribution is fixed, ensuring stable driving when climbing slopes.
lWhen LOCK mode is selected, vehicle will switch automatically to AUTO mode if vehicle speed increases.
If vehicle speed then decreases, the vehicle automatically returns to direct 4-wheel driving conditions.
NOTE:
If there is a significant difference in pressure or wear between tires, full vehicle performance is not available.
Tire conditions are detected, and LOCK mode may be prohibited, or else speeds at which LOCK mode is
enabled may be restricted.
2WD mode (indicator lamps OFF)
Vehicle is in front-wheel drive.
NOTE:
lIf front wheels are slipping in 2WD mode, do not switch to AUTO or LOCK. This can cause difficulties for
the system.
lThe shift switch even if the shift switch is in 2WD mode, the sift switch occasionally automatically change
to 4WD mode depending on the driving condition (For example; Depressing the acceleration firmly). this is
not malfunction. How ever, 4WD mode indicator lamp dose not illuminate.
4WD WARNING LAMP
Turns ON when there is a malfunction in 4WD system. It indicates that fail-safe mode is engaged and vehicle
is in 2WD.
Also turns ON when ignition switch is turned ON, for purpose of bulb check. Turns OFF approximately for 3
seconds after the engine starts if system is normal.
