PRECAUTION                                                          PFP:00011
                                                                                                                         A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                           EKS00J1N


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.

LOW SPEED WIPER OPERATION
When the ignition switch is in the ON or START position, and the front wiper switch is turned to the low posi-
tion, the BCM detects a low speed wiper ON request through the combination switch (wiper switch) reading           D
function.
The BCM then sends a front wiper (low) request signal over CAN communication lines
q    from BCM terminals 39 and 40                                                                                  E
q    to IPDM E/R terminals 39 and 40.
When IPDM E/R receives front wiper (low) request signal, it supplies ground to energize the front wiper relay.
With the front wiper relay energized, power is supplied                                                            F

q    to front wiper motor terminal 3.
With power and ground supplied, the front wiper motor operates at low speed.
                                                                                                                   H
HI SPEED WIPER OPERATION
When the ignition switch is in the ON or START position, and the front wiper switch is turned to the high posi-
tion, the BCM detects a high speed wiper ON request through the combination switch (wiper switch) reading        I
function.
The BCM then sends a front wiper (high) request signal over CAN communication lines
q    from BCM terminals 39 and 40
                                                                                                                 J
q    to IPDM E/R terminals 39 and 40.
When the IPDM E/R receives a front wiper (high) request signal, it supplies ground to energize the front wiper
and the front wiper high relays.
                                                                                                                WW
With the front wiper and the front wiper high relays energized, power is supplied
q    through front wiper relay
q    to front wiper high relay                                                                                   L
q    through IPDM E/R terminal 35
q    to front wiper motor terminal 2.
With power and ground supplied, the front wiper motor operates at high speed.                                    M
INTERMITTENT OPERATION
Wiper intermittent operation delay interval is determined from the combination of the intermittent wiper dial
position inputs and vehicle speed. During each intermittent operation delay interval, the BCM sends a front
wiper request signal to the IPDM E/R to operate the wipers.
When the ignition switch is in the ON or START position, and the front wiper switch is turned to an intermittent
position, the BCM detects a front wiper (intermittent) ON request through the combination switch (wiper
switch) reading function.
The BCM then sends a front wiper (intermittent) request signal over CAN communication lines
q    from BCM terminals 39 and 40
q    to IPDM E/R terminals 39 and 40.
When the BCM determines that combination switch status is front wiper intermittent ON, it performs the follow-
ing operations.
q    BCM detects ON/OFF status of intermittent wiper dial position.
q    BCM calculates operation interval from wiper dial position and vehicle speed signal received through CAN
     communications.


Revision: August 2006                              WW-5                                           2007 Armada
                             FRONT WIPER AND WASHER SYSTEM

q    BCM sends front wiper request signal (INT) to IPDM E/R at calculated operation interval.
When the IPDM E/R receives a front wiper request signal (INT), it supplies ground to energize the front wiper
relay. It then sends an auto-stop signal to the BCM, and conducts intermittent front wiper motor operation.
AUTO STOP OPERATION
When the wiper arms are not located at the base of the windshield, and the wiper switch is turned OFF, the
wiper motor will continue to operate until the wiper arms reach the windshield base. When the wiper arms
reach the base of windshield, front wiper motor terminals 6 and 1 are connected.
Ground is supplied
q   to IPDM E/R terminal 43
q   through front wiper motor terminal 6
q   through front wiper motor terminal 1
q   through grounds E9, E15 and E24.
The IPDM E/R sends an auto stop operation signal to the BCM through CAN communication lines.
When the BCM receives an auto stop operation signal, the BCM sends wiper stop signal to the IPDM E/R over
CAN communication lines. The IPDM E/R then de-energizes the front wiper relay.
The wiper motor will then stop the wiper arms at the STOP position.
FRONT WASHER OPERATION
When the ignition switch is in the ON or START position, and the front and rear washer switches are OFF, the
front and rear washer motor is supplied power
q    through 10A fuse (No. 9, located in the fuse block J/B)
q    through combination switch (wiper switch) terminal 14
q    through combination switch (wiper switch) terminal 13
q    to front and rear washer motor terminal 1, and
q    through combination switch (wiper switch) terminal 11
q    to front and rear washer motor terminal 2.
When the front wiper switch is in the front washer position, the BCM detects a front washer signal request
through the combination switch (wiper switch) reading function.
Combination switch ground is supplied
q    to front and rear washer motor terminal 2
q    through combination switch (wiper switch) terminal 11
q    through combination switch (wiper switch) terminal 12
q    through grounds M57, M61 and M79.
With ground supplied, the front and rear washer motor is operated in the front direction.
When the BCM detects that front washer motor has operated for 0.4 seconds or longer, the BCM uses CAN
communication and sends a wiper request signal to the IPDM E/R for low speed operation of wipers.
When the BCM detects that the washer switch is OFF, low speed operation cycles approximately 3 times and
then stops.
MIST OPERATION
When the wiper switch is temporarily placed in the mist position, wiper low speed operation cycles once and
then stops.
For additional information about wiper operation under this condition, refer to WW-5, "LOW SPEED WIPER
OPERATION" .
If the switch is held in the mist position, low speed operation continues.
FAIL-SAFE FUNCTION
The BCM includes fail-safe function to prevent malfunction of electrical components controlled by CAN com-
munications if a malfunction in CAN communications occurs.
The BCM uses CAN communications to stop output of electrical components it controls.
Until the ignition switch is turned off, the front wiper system remains in same status as just before fail-safe con-
trol was initiated. (If wiper was in low speed operation just before fail-safe, it continues low speed operation
until ignition switch is turned OFF.)
When fail-safe status is initiated, the BCM remains in standby until normal signals are received.
When normal signals are received, fail-safe status is canceled.
