FUNCTION DIAGNOSIS

HEATED STEERING WHEEL

System Diagram

INFOID:0000000001710949

System Description

INFOID:0000000001710950

The heated steering wheel switch controls the heated steering relay. When the switch is turned on, the relay is
energized and the heated steering system will operate. The heated steering system will turn off when the
steering wheel temperature reaches approximately 30

C (86

F). Heated steering system operation can also

be canceled by pressing the heated steering wheel switch again.
NOTE:
The heated steering system will operate ONLY when the steering wheel surface is below approximately 20

(68

F). If the weather is warm enough, the heated steering system may not turn on, giving the appearance

that the system does not operate.

POWER STEERING FLUID

ON-VEHICLE MAINTENANCE

POWER STEERING FLUID

Checking Fluid Level

INFOID:0000000001297914

Check fluid level, referring to the scale on the reservoir tank.
Use HOT range for fluid temperatures of 50

– 80

C (122

– 176

F).

Use COLD range for fluid temperatures of 0

– 30

C (32

– 86

F).

CAUTION:

• Do not overfill.
• Do not reuse any power steering fluid.
• Recommended fluid is Genuine NISSAN PSF or equivalent.

Refer to

MA-10, "Fluids and Lubricants"

Checking Fluid Leakage

INFOID:0000000001297915

Check the hydraulic piping lines for improper attachment, leaks,
cracks, damage, loose connections, chafing and deterioration.

Run the engine until the fluid temperature reaches 50

– 80

(122

– 176

F) in the reservoir tank. Keep engine speed idle.

CAUTION:

Do not allow steering fluid reservoir tank to go below the
MIN level line. Check tank frequently and add fluid as
needed.

Turn the steering wheel to the right and left several times.

Hold the steering wheel at each “locked” position for five sec-
onds to check for fluid leakage.

CAUTION:

Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibil-
ity that the oil pump may be damaged.)

If fluid leakage at a connection is noticed, loosen the connection and then retighten. Do not over-tighten
connector as this can damage O-ring, washer and connector. Refer to

ST-14

and

ST-26

If fluid leakage from the oil pump is noticed, check the oil pump. Refer to

ST-14

Check steering gear boots for accumulation of fluid, indicating a leak from the steering gear.

CAUTION:

Do not reuse copper washers.

Air Bleeding Hydraulic System

INFOID:0000000001297916

Incomplete air bleeding causes the following:

• Air bubbles in reservoir tank
• Clicking noise in oil pump
• Excessive buzzing in oil pump
When this happens bleed the air again.
NOTE:
When the vehicle is stationary or while the steering wheel is being turned slowly, some noise may be heard
from the oil pump or gear. This noise is normal and does not affect any system.
1.

Check for fluid leakage. Refer to

ST-10, "Checking Fluid Leakage"

Start the engine and turn the steering wheel fully to the right and left several times.

CAUTION:

Do not allow steering fluid reservoir tank to go below the MIN level line. Check tank frequently and
add fluid as needed.

Run the engine at idle speed. Hold the steering wheel at each "locked" position for three seconds.

CAUTION:
