INSPECTION AFTER DISASSEMBLY
●If pulley is cracked or deformed, replace it.
●If an oil leak is found around pulley shaft oil seal, replace the seal.
●If serration on pulley or pulley shaft is deformed or worn, replace it.
ASSEMBLY
1. Assemble oil pump, noting the following instructions.
●Make sure O-rings and oil seal are properly installed.
●Always install new O-rings and oil seal.
●Be careful of oil seal direction.
●Cam ring, rotor and vanes must be replaced as a set if neces-
sary.
●Coat each part with DEXRONTM III or equivalent when
assembling.
2. Pay attention to the direction of rotor.
3. When assembling vanes to rotor, rounded surfaces of vanes
must face cam ring side.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EHS000QI
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 harness connec-
tors.
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
minutes.
For approximately 3 minutes after the cables is 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.
Trouble Diagnosis PrecautionEHS000BI
When you read wiring diagrams, refer to the followings:
●“HOW TO READ WIRING DIAGRAMS” in GI section
●PG-2, "POWER SUPPLY ROUTING" in PG section
When you perform trouble diagnosis, refer to the followings:
●“HOW TO FOLLOW TEST GROUP IN TROUBLE DIAGNOSIS” in GI section
●“HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT” in GI section
Check for any service bulletins before servicing the vehicle.
