On-Vehicle Inspection and ServiceINFOID:0000000001327712
CHECKING CONDITION OF INSTALLATION
Check installation condition of steering gear assemb ly, front suspension, axle and steering column.
Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
Check if the mounting bolts for steering gear assembly are loose or not. Refer to PS-17
.
CHECKING STEERING WHEEL PLAY
1. Set tires to the straight ahead, start engine, then turn steering wheel to the left and right lightly, and mea-
sure steering wheel movement on the outer circumfe rence when steering wheel is turned up to the point
where tires start moving.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-5,
"Wheel Alignment Inspection".
1. Set vehicle to the straight direction, chec k if steering wheel is in the neutral position.
2. If it is not in the neutral position, remo ve steering wheel and reinstall it correctly.
3. If the neutral position cannot adjust in the two teeth of steering gear assembly, loosen outer socket lock
nuts of steering outer sockets, then adjust outer so cket by the same amount in the opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating te mperature. [Make sure temperature of fluid is
approximately 50 to 80 °C (122 to 176 °F).]
NOTE:
Tires need to be inflated normal pressure.
4. Check steering wheel turning force when steering wheel has been turned 360 ° from neutral position.
NOTE:
Multiply the distance L from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
5. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-27, "
On-Vehicle Inspection and Service".
End play of the axle direction for steering wheel : 0 mm (0 in)

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612877
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
INFOID:0000000001327741
Do not use electrical test equipment to check SRS ci rcuits 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 remov ed, it is still possible for the air bag and seat belt pre-
tensioner to deploy. Therefore, do not work on any SR S 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 installa-
tion and replace as required.
The spiral cable must be aligned with the neutral position since its rotations are limited. Do not turn steering
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.
Disposal, recycling, and transportation of air bag m odules and seat belt pre-tensioners should be performed
in compliance with applicable federal, state and local laws and regulations.
Occupant Classification System PrecautionINFOID:0000000001327742
Replace occupant classification system control uni t and passenger front seat cushion as an assembly.
Refer to Refer to Service Manual .

COLLISION DIAGNOSIS
For Frontal CollisionINFOID:0000000001327773
To repair the SRS, perform the following steps.
When SRS (except the front side air bag and sidecurt ain air bag modules) is activated in a collision:
1. Replace the diagnosis sensor unit.
2. Remove the air bag modules (except the front side air bag modulesand side curtain air bag modules),
crash zone sensor assembly, bracket andseat belt pre-tensioner assemblies.
3. Check the SRS components using the table below:
- Replace any SRS components showing visible signs of damage (dents,cracks and deformation).
4. Install new air bag modules (except the front side air bag modules and side curtain air bag modules) crash
zone sensor assembly, bracket and seat belt pre-tensioner assemblies.
5. Conduct self-diagnosis using CONSULT-III or “AIR BAG”warning lamp. Refer to SRS-23, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
When SRS is not acti vated in a collision:
1. Check the SRS components using the table below:
- Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
2. Conduct self-diagnosis using CONSULT-III or “AIR BAG” warning lamp. Refer to SRS-23, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
When only one front air bag modu le is activated in a collision:
1. Replace the following components:
- Diagnosis sensor unit
- Crash zone sensor
- Activated front air bag and seat belt pre-tensioner.
2. Check the other SRS components using the table below. (Refer to “SRS is NOT activated”.)
- Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
3. Conduct self-diagnosis using CONSULT-III or “AIR BAG” warning lamp. Refer to SRS-23, "
SRS Operation
Check" for details. Ensure entire SRS operates properly.
Only one front air bag may inflate a crash, depending on t he crash severity and whether the front occupants
are belted or unbelted. This does not indicate improper performance of the system. Perform self-diagnosis to
make sure the entire SRS operates properly.

and the buzzer operations. It also has a judgment function to detect
a system malfunction.
LOW TIRE PRESSURE WARNING LAMP
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter low tire pressure warn-
ing lamp is activated.
Low Tire pressure Warning Lamp Indication
Note 1: Standard air pressure is for 220 kpa (2.2 kg/cm2, 32 psi) vehicles.
RUN-FLAT TIRE WARNING LAMP
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is

Self-DiagnosisINFOID:0000000001327584
DESCRIPTION
During driving, the low tire pressure warning syste m receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) of this
system has pressure judgment and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the
warning lamps in the combination meter comes on. To start the self-diagnostic results mode, ground terminal
of the tire pressure warning check connector. The malf unction location is indicated by the warning lamp flash-
ing and the buzzer sounds.
