O-Ring Part Numbers and Specifications
*: Always check with the Parts Department for the latest parts information.
WARNING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
lWhen the compressor is removed, store it in the same position as it is when mounted on the car.
Failure to do so will cause lubricant to enter the low pressure chamber.
lWhen connecting tubes, always use a torque wrench and a back-up wrench.
lAfter disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.
lWhen installing an air conditioner in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for
connection.
lAllow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
lThoroughly remove moisture from the refrigeration system before charging the refrigerant.
lAlways replace used O-rings.
lWhen connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.
Lubricant name: NISSAN A/C System Lubricant Type S (DH-PS) or equivalent
Part number: KLH00-PAGS0
lO-ring must be closely attached to dented portion of tube.
lWhen replacing the O-ring, be careful not to damage O-ring and tube.
lConnect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.

WARNING:
Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If
accidental system discharge occurs, ventilate work area before resuming service. Additional health
and safety information may be obtained from refrigerant and lubricant manufacturers.

PRECAUTIONSPFP:00011
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.

Auto Active TestEKS00PAC
DESCRIPTION
lIn auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to
the following systems:
–Rear window defogger
–Front wiper
–Tail lamps, front fog lamps, parking lamps and license plate lamps
–Headlamps (HI, LO)
–A/C compressor (magnetic clutch)
–Cooling fan
–Oil pressure warning lamp
OPERATION PROCEDURE
1. Close hood and front door passenger side, and then lift wiper arms away from windshield (to prevent
glass damage by wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON and, within 20 seconds, press driver's door switch 10 times (close other doors).
Then turn ignition switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, oil pressure warning lamp starts blinking.
6. After a series of operations is repeated three times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
CAUTION:
Be sure to performBL-39, "
Check Door Switch"when the auto active test cannot be performed.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following six steps are repeated three times.
A: Oil pressure warning lamp is blinking when the auto active test operating.
Operation steps
Concept of Auto Active Test
lIPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN commu-
nication line. Therefore, when auto active test mode is activated successfully, CAN communication
between IPDM E/R and BCM is normal.
lIf any of the systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.
