POWER STEERING FLUID
InspectionINFOID:0000000009461251
FLUID LEVEL
Check power steering fluid level at the scale on reservoir tank cap
indicator.
• Check power steering fluid level with engine stopped and the fluid temp between 0 – 30 ° C (32 – 86 ° F).
• Power steering fluid level should be between the hatching area of the indicator on the power steering reservoir tank cap.
CAUTION:
• Do not overfill.
• Do not reuse used power steering fluid.
• Recommended power steering fluid is Genuine NISSAN E-
PSF or equivalent. Refer to MA-11, "FOR USA AND CANADA :
Fluids and Lubricants".
FLUID LEAKAGE
Check the power steering hydraulic system for leaks, cracks, dam-
age, loose connections, chafing or det erioration. Repair or replace
as necessary.
1. Start engine and allow engine to idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. Damage to power steering oil pump may
occur.
4. If power steering fluid leakage at connections is noticed, loosen flare nut and retighten.
CAUTION:
Do not over tighten flare nut as damage to O-ring and connection can occur.
5. If power steering fluid leakage from the power steer ing oil pump is noticed, repair connection or replace
power steering oil pump. Refer to ST-15, "Inspection"
.
6. Check steering gear boots for accumulation of power st eering fluid. Power steering fluid indicates a leak
from the power steering gear, replace as necessary. Refer to ST-36, "Removal and Installation"
.

DRAINING
1. Disconnect the high and low pressure piping from power steering gear.
2. Drain power steering fluid into a suitable container.
REFILLING
1. Fill power steering reservoir while checking power steering fluid level.
2. Bleed air from power steering hydraulic system. Refer to ST-30, "Air Bleeding Hydraulic System"
.
3. Check for power steering fluid leaks.
Air Bleeding Hydraulic SystemINFOID:0000000009461267
AIR BLEEDING HYDRAULIC SYSTEM
If air bleeding is not complete, excessive noise in the power steering oil pump will be present.
1. Make sure engine is off.
2. Turn the steering wheel from the full right stop pos ition and then to full left stop position several times.
Repeat until bubbles are no longer being generated in the reservoir.
3. When the power steering fluid level lowers, refill the reservoir. CAUTION:
Do not allow the power steerin g fluid level to drop below
the hatching area.
4. Repeat steps one and two until the power steering fluid level stabilizes.
5. Start the engine and run at idle.
6. Turn the steering wheel from the full right stop pos ition and then to full left stop position several times.
Repeat until bubbles or fluid discoloration are no longer being generated in the reservoir.
7. When the power steering fluid level lowers, refill the reservoir.
8. Stop the engine.
9. Verify proper power steering fluid level. Power steering fluid level should be between the hatching area of the indicator on
the power steering reservoir tank cap.

HYDRAULIC PUMP ELECTRIC POWER STEERING SYSTEM
HYDRAULIC PUMP ELECTRIC POWER ST EERING SYSTEM : System Description
INFOID:0000000009460344
• The system is composed primarily of the power steeri ng oil pump assembly (power steering control module,
power steering motor, power steering oil pump, and reservoir tank), hydraulic pipes, and steering gear
assembly.
• The power steering control module controls the speed of the power steering motor according to the vehicle
speed and steering angle speed. By changing the power st eering oil pump flow, the power steering control
module controls the steering assist force.
• According to the power steering motor control, the sy stem hydraulic pressure is transmitted from the power
steering motor to power steering oil pump. The power steering oil pump is driven by the system hydraulic
pressure.
• After engine start, the hydraulic pump electric power steering system performs control.
• When a malfunction occurs in the system, the fail-safe function stops the hydraulic pump electric power
steering system (manual steering state) or restricts it s operation (certain steering assist force). Refer to STC-
8, "HYDRAULIC PUMP ELECTRIC POWER STEERING SYSTEM : Fail-safe".
• When the power steering function is used continuously in an extreme manner, the protective function
reduces the output to the power steering motor. Refer to STC-9, "HYDRAULIC PUMP ELECTRIC POWER
STEERING SYSTEM : Protection Function".

SYSTEM
When Steering Wheel is Rotated to the Left
The hydraulic routes open from power steering pump to gear housing left side and from gear housing right
side to reservoir tank, providing right direction assist force to the rack.
CONDITIONS FOR HYDRAULIC PUMP ELECTR IC POWER STEERING WARNING LAMP ON
• When the hydraulic pump electric power steering syst em is operating and steering assist force is being gen-
erated, the hydraulic pump electric power steering warning lamp is OFF.
• When the hydraulic pump electric power steering system is stopped by the fail-safe or protective function
and steering assist force is not being generated, the hy draulic pump electric power steering warning lamp
turns ON to inform the driver that t he system is in the manual steering state.
NOTE:
When the hydraulic pump electric power steering system warning lamp turns ON according to the protection
system, the cause is internal high temperature state of the hydraulic pump electric power steering system.
By stopping the engine, internal temperature of the s ystem decreases. After starting the engine, the system
returns to the normal state and the hydraulic pump elec tric power steering system warning lamp turns OFF.
(The system is not malfunctioning.) For informat ion about the protective function, refer to STC-9, "HYDRAU-
LIC PUMP ELECTRIC POWER STEERING SYSTEM : Protection Function".
• When the ignition switch is turned ON, this lamp turn s ON for lamp check (system check). When the system
is operating normally, the lamp turns OFF after the engine starts.
HYDRAULIC PUMP ELECTRIC POWE R STEERING SYSTEM : Fail-safeINFOID:0000000009460345
When an error occurs in the hydraulic pump electric pow er steering system, fail-safe brings the system to a
halt (manual steering) or restricted (constant steering assi st level) state. When the system is in a halt state,
fail-safe turns ON the hydraulic pump electric power steer ing warning lamp to warn the driver that the hydrau-
lic pump electric power steering system is in the manual steering state.

HYDRAULIC PUMP ELECTRIC POWER STEE RING SYSTEM : Protection Function
INFOID:0000000009460346
• When the steering wheel is operated repeatedly or turned all the way for a long period during parking or low
speed driving, the function of the hydraulic pump elec tric power steering system becomes limited to prevent
the system from overheating. Cont inued operation of the steering wheel will cause the hydraulic pump elec-
tric power steering system to stop and the hydraulic pum p electric power steering system warning lamp may
come ON. In this case, the steering wheel operation temporarily becomes hard. This is not a malfunction.
When the engine is turned OFF (ignition switch OFF) and steering operation is stopped for a while, the tem-
perature of the hydraulic pump electric power steer ing system decreases and the steering operation returns
to normal after restarting the engine.
• Then, the hydraulic pump electric power steering syste m warning lamp turns OFF. If the system is OFF
under the protection state, the hydraulic pump electr ic power steering system warning lamp turns ON to
warn that the system is in the manual steering state. (This is not a system malfunction.) In addition, the fol-
lowing DTC remains to distinguish from malfunction.

the system from overheating. If the steering wheel is operated further more, the hydraulic pump electric
power steering system stops and the hydraulic pump el ectric power steering system warning lamp may be
turned ON. In this case, the steering wheel operation temporarily becomes hard. This is not a malfunction.
When the engine is turned OFF (ignition switch OFF) and steering operation is stopped for a while, the tem-
