PRECAUTION

PRECAUTION PFP:00011
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS00I1Q

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
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 C
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: D
q 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. E
q 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. F
q 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.
G
Wiring Diagrams and Trouble Diagnosis EKS001IQ

When reading wiring diagrams, refer to the following:
H
q Refer to GI-14, "How to Read Wiring Diagrams" .
q Refer to PG-2, "POWER SUPPLY ROUTING" for power distribution circuit.
When performing trouble diagnosis, refer to the following: I
q Refer to GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" .
q Refer to GI-26, "How to Perform Efficient Diagnosis for an Electrical Incident" .

FRONT WIPER AND WASHER SYSTEM (WITH RAIN SENSOR)

FRONT WIPER AND WASHER SYSTEM (WITH RAIN SENSOR) PFP:28536

Component Parts and Harness Connector Location EKS00HCX

PKIA9806E

System Description EKS00HCY

q When front wiper switch is turned to INT position, wiper performs intermittent operation, low-speed opera-
tion, and high-speed operation from stop according to water drop increase rate on windshield detected by
rain sensor.
q If front wiper switch is turned to INT position when ignition switch is ON, wiper operates once without any
relation to the water drop detection. After that, wiper operates according to the amount of rainfall.
q When ignition switch is turned ON with front wiper switch turned to INT position, wiper operates only when
rain sensor detects water drops.
q Rain sensitivity can be changed by sensitivity adjustment volume. Change from LO continuous operation
to HI continuous operation is decided without any relation to sensitivity adjustment volume.
q If rain sensor malfunctions, rain sensor function will stop. But, the function operates as vehicle speed
sensing wiper during driving and operates intermittent operation according to INT-volume switch with
vehicle stopped.
q Stop wiper operation when windshield temperature exceeds 70
