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

EKS006WM

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 may include seat belt switch inputs and dual stage front air bag modules. If
equipped with 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 Manual.

The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.

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.

●

The vehicle may be equipped with a passenger air bag deactivation switch which can be operated
by the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled
and will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled
and could inflate for certain types of collision. After SRS maintenance or repair, make sure the
passenger air bag deactivation switch is in the same position (ON or OFF) as when the vehicle
arrived for service.

Wiring Diagrams and Trouble Diagnosis

EKS006WN

System Description

EKS006WO

WIPER OPERATION
Models Without Intermittent Wipers

The front wiper switch is controlled by a lever built into the combination switch.
There are two front wiper switch positions:

●

LO speed

●

HI speed

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 B.

Low and High Speed Wiper Operation
Ground is supplied to front wiper switch terminal 17 through body grounds E12 and E54.
With the front wiper switch in the LO position, ground is supplied

●

to front wiper motor terminal L

●

through front wiper switch terminal 14.

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

●

to front wiper motor terminal H

●

through front wiper switch terminal 16.

With power and ground supplied, the front wiper motor operates at high speed.
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.

Models With Intermittent Wipers

The front wiper switch is controlled by a lever built into the combination switch.
There are three front 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 B and

●

to front wiper motor terminal L

●

through front wiper switch terminal 14.

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

●

to front wiper motor terminal H

●

through front wiper switch terminal 16.

With power and ground supplied, the front wiper motor operates at high speed.

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

●

through wiper motor terminal L

●

through 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 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.
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 front wiper switch.
The front 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.
