Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS001TO
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 harnesses or
harness connectors.
Precautions for Procedures without Cowl Top Cover
NKS002TY
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

●
to combination switch terminal 12
●
through grounds M14 and M78.
LOW SPEED WIPER OPERATION
When the front wiper switch is in LO position, BCM detects the FR WIPER LOW (ON) by BCM combination
switch reading function. BCM sends front wiper request signal (LO) through CAN communication.
When receiving front wiper request signal (LO), IPDM E/R turns ON front wiper relay in IPDM E/R. IPDM E/R
supplies power
●
through IPDM E/R terminal 21, front wiper high relay and front wiper relay
●
to front wiper motor terminal 3.
Ground is supplied
●
to front wiper motor terminal 1
●
through grounds E13, E26 and E28.
With power and ground is supplied, the front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION
When the front wiper switch is in HI position, BCM detects the FR WIPER HI (HI) by BCM combination switch
reading function. BCM sends front wiper request signal (HI) through CAN communication.
When receiving front wiper request signal (HI), IPDM E/R turns ON front wiper relay and front wiper high relay
in IPDM E/R. IPDM E/R supplies power
●
through IPDM E/R terminal 31, front wiper high relay and front wiper relay
●
to front wiper motor terminal 2.
Ground is supplied
●
to front wiper motor terminal 1
●
through grounds E13, E26 and E28.
With power and ground is supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Front wiper intermittent operation is determined from a combination of 3 switches (INT VOLUME 1, 2, and 3)
and vehicle speed signal*.
When the front wiper switch is in INT position, BCM detects the FR WIPER INT (ON) and ON/OFF status of
the INT VOLUME 1, 2, and 3 by BCM combination switch reading function. BCM judges the condition of wiper
intermittent dial position by ON/OFF status of INT VOLUME 1, 2, and 3 .
BCM sends front wiper request signal (1LOW) at certain intervals through CAN communication. The interval is
calculated by wiper intermittent dial position and vehicle speed signal received from combination meter
through CAN communication.
When receiving front wiper request signal (1LOW), IPDM E/R turns ON front wiper relay in IPDM E/R, and
operates front wiper motor at low speed. Then IPDM E/R detects wiper arms reach to the stop position via
wiper auto stop signal from front wiper motor, IPDM E/R turns OFF front wiper relay, and sends front wiper
auto stop signal (ON) to BCM through CAN communication, and controls intermittent operation.
WW-6
FRONT WIPER AND WASHER SYSTEM
Revision: 2006 August
2006 Murano
Wiper Intermittent Dial Position Setting
Example: For wiper intermittent dial position 1
Using combination switch reading function, BCM detects ON/OFF status of INT VOLUME 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper Intermittent dial position 1.
●
INT VOLUME 1: ON (Continuity exists between combination switch output 3 and input 1.)
●
INT VOLUME 2: ON (Continuity exists between combination switch output 5 and input 1.)
●
INT VOLUME 3: ON (Continuity exists between combination switch output 4 and input 2.)
BCM determines front wiper intermittent operation interval from wiper dial position 1 and vehicle speed*, and
sends wiper request signal (INT) to IPDM E/R.
*: Vehicle-speed-sensing intermittent wiper function reads vehicle speed signal when the function is ON. It is
set in OFF at the factory shipment. Vehicle-speed-sensing intermittent wiper function ON/OFF can be
changed by the CONSULT-II. Refer to
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, power is provided
●
from IPDM E/R terminal 21
●
to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
When wiper arms reach base of windshield, front wiper motor terminals 1 and 4 are connected, and ground is
supplied
●
to IPDM E/R terminal 32
●
through front wiper motor terminal 4
●
through front wiper motor terminal 1
●
through grounds E13, E26 and E28.
Then the IPDM E/R sends front wiper auto stop signal (ON) to BCM with CAN communication line.
When the BCM receives front wiper auto stop signal (ON), BCM sends front wiper request signal (OFF) to
IPDM E/R with CAN communication line.
IPDM E/R stops wiper motor. Wiper motor will then stop wiper arms at the STOP position.
WASHER OPERATION
When the front washer switch is ON position, front and rear washer pump operates, and BCM detects the FR
WASHER (ON) by BCM combination switch reading function. Combination switch supplies power
●
through combination switch terminal 13
●
to front and rear washer pump terminal 1
Ground is supplied
●
to front and rear washer pump terminal 2
●
through combination switch terminal 11
●
to combination switch terminal 12
●
through grounds M14 and M78.
When BCM detects the FR WASHER (ON) for 0.4 seconds or longer, BCM sends front wiper request signal
(LO) through CAN communication. IPDM E/R operates front wiper motor at low speed.
When BCM detects the front washer switch is OFF, low speed wiper operation cycles approximately 2 times
and stops.
