PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS0079K
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 harnesses or
harness connectors.
Wiring Diagrams and Trouble Diagnosis EKS0079L
When you read wiring diagrams, refer to the followings:

Refer to GI-14, "How to Read Wiring Diagrams" in GI section

Refer to PG-2, "POWER SUPPLY ROUTING" for power distribution circuit in PG section
When you perform trouble diagnosis, refer to the followings:

Refer to GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section

Refer to GI-23, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section

FRONT WIPER AND WASHER SYSTEM

FRONT WIPER AND WASHER SYSTEMPFP:28810
System DescriptionEKS0032N
WIPER OPERATION
The wiper switch is controlled by a lever built into the combination switch.
There are three wiper switch positions:

LO speed

HI speed

INT (Intermittent)
With the ignition switch in the ON or START position, power is supplied

through 20A fuse [No. 6, located in the fuse block (J/B)]

to front wiper motor terminal 2.
Low and High Speed Wiper Operation
Ground is supplied to front wiper and washer switch terminal 17 through body grounds E24 and E50.
When the wiper switch is placed in the LO position, ground is supplied

through front wiper and washer switch terminal 14

to front wiper motor terminal 3.
With power and ground supplied, the wiper motor operates at low speed.
When the wiper switch is placed in the HI position, ground is supplied

through front wiper and washer switch terminal 16

to front wiper motor terminal 5.
With power and ground supplied, the wiper motor operates at high speed.
Auto Stop Operation
With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When wiper arms are not located at base of windshield with wiper switch OFF, ground is provided

from front wiper and washer switch terminal 14

to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
Ground is also supplied

through front wiper and washer switch terminal 13

to front wiper motor terminal 4

through terminal 1 of the front wiper motor terminal 1 and

through grounds E24 and E50.
When wiper arms reach base of windshield, front wiper motor terminals 2 and 4 are connected instead of ter-
minals 1 and 4. Wiper motor will then stop wiper arms at the STOP position.
Intermittent Operation
The front wiper motor operates the wiper arms one time at low speed at a set interval of approximately 1 to 13
seconds. This feature is controlled by the wiper amplifier (INT SW) combined with front wiper and washer
switch.
When the wiper switch is placed in the INT position, ground is supplied to wiper amplifier.
The desired interval time is input to wiper amplifier (INT VR) from wiper volume switch combined with front
wiper and washer switch.
Then intermittent ground is supplied

through wiper amplifier (OUTPUT) and

through front wiper and washer switch terminal 14

to front wiper motor terminal 3
The wiper motor operates at low speed at the desired interval.
WASHER OPERATION
With the ignition switch in the ON or START position, power is supplied

through 20A fuse [No. 6, located in the fuse block (J/B)]

to front washer motor terminal 1.
When the lever is pulled to the WASH position, ground is supplied

from grounds E24 and E50

through front wiper and washer switch terminal 17, and

through front wiper and washer switch terminal 18

to front washer motor terminal 2.
With power and ground supplied, the washer motor operates.
When the lever is pulled to the WASH position for one second or more, the wiper motor operates at low speed
for approximately 3 seconds to clean windshield. This feature is controlled by the wiper amplifier in the same
manner as the intermittent operation.

1. Prior to front wiper arm installation, turn on wiper switch to oper-
ate front wiper motor and then turn it “OFF” (Auto Stop).

the blade center to clearance “L1” & “L2” immediately before
tightening nut.
3. Eject washer fluid. Turn on front wiper switch to operate front
wiper motor and then turn it “OFF”.
4. Ensure that front wiper blades stop within clearance “L1” & “L2”.

Tighten front wiper arm nuts to specified torque.

Before reinstalling front wiper arm, clean up the pivot area as
illustrated. This will reduce possibility of front wiper arm loose-
ness.
