INSPECTION AFTER REMOVAL

Check if there is something wrong with jacket tube of steering column assembly and collar etc. And then if
they are damaged, replace with new one.

If vehicle has a collision light shocked, check column length “L”
as shown in the figure. Then if it is out of the specified value,
replace with new one.

Check the turning torque of steering column with preload gauge
(SST). If it is out of the specified value, repair it or replace with
new one.
INSTALLATION

Refer to PS-12, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing steering components, check wheel alignment. Refer to FSU-6,
"Wheel Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .
INSPECTION AFTER INSTALLATION

After installing steering column to vehicle, check tilt device and
its operation range. Ranges of operation are shown in the figure.

Check if steering wheel operation can turn to the end of the left
and right smoothly.Steering column length “L”: 572 mm (22.52 in)

CAUTION:
Spiral cable may snap due to steering operation if steering column is separated from steering gear
assembly. Therefore fix steering wheel with a string to avoid turns.
REMOVAL
1. Set wheels in the straight-ahead position.
2. Remove tires from vehicle with power tool.
3. Remove undercover with power tool.
4. Confirm slit of lower joint fits with the projection on rear cover
cap, furthermore marking position on steering gear assembly
nearly fits with the projection on rear cover cap.
5. Remove cotter pin at steering outer socket, then loosen mount-
ing nut.
6. Use a ball joint remover (SST) to remove steering outer socket
from steering knuckle. Be careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to
threads and to prevent ball joint remover (SST) from com-
ing off.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AHS000HB
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
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.
Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceAHS000HC

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 turn steer-
ing wheel and 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 seat mounted front side air bag module standing with the stud bolt side facing
down.

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.

Always replace instrument panel pad following front passenger air bag deployment.
Wiring Diagrams and Trouble DiagnosisAHS000HE
When you read wiring diagrams, refer to the following:

GI-15, "How to Read Wiring Diagrams" in GI section

PG-3, "POWER SUPPLY ROUTING CIRCUIT" in PG section
When you perform trouble diagnosis, refer to the following:

GI-11, "How to Follow Trouble Diagnoses" in GI section

GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section
Check for any service bulletins before servicing the vehicle.
