Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS00N4A
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:
lTo 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.
lImproper 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.
lDo 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.
Wiring Diagrams and Trouble DiagnosisEKS00LIU
When you read wiring diagrams, refer to the following:
lRefer toGI-15, "HowtoReadWiringDiagrams"in GI section.
lRefer toPG-4, "POWER SUPPLY ROUTING CIRCUIT"for power distribution.
When you perform trouble diagnosis, refer to the following:
lRefer toGI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES"in GI section.
lRefer toGI-24, "How to Perform Efficient Diagnosis for an Electrical Incident"in GI section.

APPEARANCE AND NOISE INSPECTION
lCheck the propeller shaft tube surface for dents or cracks. If damaged, replace the propeller shaft assem-
bly.
lCheck the bearings for noise and damage. Repair or replace the bearings as necessary.
PROPELLER SHAFT VIBRATION
If a vibration is present at high speed, inspect the propeller shaft runout first.
1. Measure the runout of the propeller shaft tube at several points
by rotating the final drive companion flange with your hands.
For measuring point, refer toPR-3, "
Propeller Shaft Runout
Measuring Point".
2. If the runout exceeds specifications, disconnect the propeller
shaft at the final drive companion flange; then rotate the com-
panion flange 90°,180°and 270°and reconnect the propeller
shaft.
3. Check the runout again. If the runout still exceeds specifications,
replace the propeller shaft assembly.
4. After installation, check for vibration by driving the vehicle.

Precautions for Steering SystemEGS001L9
lIn case of removing steering gear assembly, make the final tightening with grounded and unloaded vehi-
cle condition, and then check wheel alignment.
lObserve the following precautions when disassembling.
–Before disassembly, thoroughly clean the outside of the unit.
–Disassembly should be done in a clean work area. It is important to prevent the internal parts from becom-
ing contaminated by dirt or other foreign matter.
–For easier and proper assembly, place disassembled parts in order on a parts rack.
–Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere
with their operation.
–Do not reuse non-reusable parts.
–Before assembling, apply the specified grease to the directed parts.
