PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EGS000IZ
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
CautionEGS00049

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 manual. 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 DEXRONTM III or equivalent 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.

If following part is scratched after disassembly of steering pump, replace applicable part: case, rear body,
side plate, pulley, rotor, vane, or flow control valve.

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

Seals and copper washers must not be reused.

Removal and InstallationEGS0004I
REMOVAL
1. Remove cotter pin, and loosen mounting nut. Remove tie rod from steering knuckle with a pitman arm
puller.
CAUTION:

Be careful not to damage dust boot at ball joint of tie rod.

Before using pitman arm puller (multi-purpose tool), loosely tighten nut for temporary holding.
2. Mark lower joint and steering gear with paint for easy installation. Remove pinch bolt from gear side of
lower joint.
3. Remove high pressure-side tube and low pressure-side hose of hydraulic piping from steering gear.
4. Remove mounting nuts on upper portion of stabilizer connecting rod and stabilizer clamp mounting bolts.
Move stabilizer toward vehicle front.
5. Remove steering gear assembly mounting bolts and nuts. Remove power steering tube bracket and
steering gear assembly from suspension member.
6. Tilt steering gear to prevent any contact with other parts. Then remove it from right side of vehicle.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.

After installation, bleed air. Refer to PS-6, "Bleeding Hydraulic System" .

Remove mounting bolt and nut from upper portion of lower joint. This will facilitate installation of lower joint
to steering gear. Then slide lower joint in place.

Check lower slit of lower joint is engaged with projection on rear
cover cap. Install pinch bolt for lower portion of lower joint.
Check steering gear is in straight-ahead position. Also check
rear cover is in position shown in figure. Then install lower joint
to steering gear.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceEHS000BH

Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.

Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.

Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before instal-
lation and replace as required.

The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.

Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and place front side air bag module standing with stud bolt side setting bottom.

Conduct self-diagnosis to check entire SRS for proper function after replacing any components.

After air bag inflates, the front instrument panel assembly should be replaced if damaged.
