PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” EKS0035H

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. 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
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:
● 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.

 FRONT WIPER AND WASHER

Auto Stop Operation

When the front wiper switch is turned OFF, the front wiper motor will continue to operate at low speed until
wiper blades reach windshield base.
When wiper blades are not located at base of windshield with front wiper switch OFF, ground is supplied
● to front wiper motor terminal L
● through front wiper switch terminal 14
● through front wiper switch terminal 13
● through front wiper motor terminal P
● through front wiper motor terminal E
● through body grounds E12 and E54.
When wiper blades reach base of windshield, front wiper motor terminals B and P are connected instead of
terminals P and E.
Battery power is then supplied
● through front wiper motor terminal P
● to front wiper switch terminal 13.
With battery voltage supplied to front wiper switch terminal 13, the front wiper switch will stop the front wiper
motor with the wiper blades at the PARK position.
Intermittent Operation
The wiper blades perform a single wiping operation, followed by a delay interval which is adjustable from
approximately 3 to 13 seconds, after which the cycle repeats. This feature is controlled by the front wiper
switch.
ProCarManuals.com

When the front wiper switch is placed in the INT position, ground is supplied intermittently
● to front wiper motor terminal L
● through front wiper switch terminal 14
● through front wiper switch terminal 17
● through body grounds E12 and E54.
The delay interval time is controlled by the wiper switch.
The wiper motor operates at low speed at the desired delay 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 +.
When the lever is pulled to the WASH position, ground is supplied
● to front washer motor terminal –
● from front wiper switch terminal 18
● through front wiper switch terminal 17
● through body grounds E12 and E54.
With power and ground supplied, the front washer motor operates.
Models With Intermittent Wipers
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 switch in the same
manner as the intermittent operation.
