PRECAUTIONS

PFP:00001

Precautions for Models with SRS Air Bag and Seat Belt Pre-tensioner

EGS000N3

WARNING:

●

Before removing and installing components and harnesses of SRS air bag and seat belt pre-
tensioner system, turn ignition switch OFF, disconnect battery ground cable, and wait at least 3
minutes. (This discharges electricity held in the air bag sensor unit's additional power circuit.)

●

Do not use pneumatic or electric tools to remove and install the components.

●

Do not solder SRS air bag and seat belt pre-tensioner system harnesses when making repairs.
Make sure harness is not pinched and there is no contact with other components.

●

When checking the SRS air bag and the seat belt pre-tensioner circuit or the components of each
system, do not use an electric tester such as a circuit tester. (This is to prevent accidental trigger-
ing caused by the weak electric current of a tester.)

●

Never insert foreign material (such as a screwdriver) in the air bag module and seat belt pre-
tensioner connectors. (The units may be actuated by mistake by static electricity.)

●

Seat belt pre-tensioner and SRS air bag harnesses can be distinguished from other harnesses by
their yellow connectors.

●

When servicing, refer to “SB Seat Belt” and “SRS Air Bag” for safety.

Caution

EGS000N4

●

Always follow the warnings and the cautions below in disassembly procedures:

–

Work in a clean, dust-free place. No dust proof device is necessary.

–

Clean outside of unit before disassembly.

–

Clean parts to be disassembled. Be careful not to allow any dirt or other foreign materials to enter or con-
tact with parts.

–

Assemble disassembled parts properly, following order shown in instruction. If work has been suspended in
the middle of assembly, place a clean cover over parts. This will prevent them from being contaminated.

–

Use paper towels when removing dirt and other foreign materials. Cloth shop towels can leave lint on
cleaned parts that might affect operation of parts.

–

Clean disassembled parts (except rubber parts) with kerosene. Drain oil by blowing with air or absorbing
with shop papers.

–

Before assembling, apply DEXRON

TM

III or Nissan Power Steering Fluid Special to O-rings and seals.

–

Replace gaskets and O-rings with new ones. Be careful not to damage any O-rings, oil seals, and gaskets
during assembly.

●

Mark source of fluid leak with a white marker for identification.

●

Seals and copper washers must not be reused.

POWER STEERING FLUID

PFP:KLF20

Checking Fluid Level

EGS000N7

●

Check the fluid level with the engine OFF.

●

Check 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.

●

Note 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:

●

Never reuse drained power steering fluid.

●

Use DEXRON

TM

III, Nissan Power Steering Fluid Special or equivalent.

Checking Fluid Leak

EGS000N8

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 counterclockwise 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 System

EGS000N9

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.

●

Bubbles are created in reservoir tank.

●

Rattling noise can be heard from oil pump.

●

Whining noise can be heard from oil pump.

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.
