Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                           NKS000Z3


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.

Example: For wiper intermittent dial position 1
Using combination switch reading function, BCM detects ON/OFF status of intermittent operation INT VOL-
UME 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper Intermittent dial position 1.
q    Intermittent operation INT VOLUME 1: ON (Continuity exists between combination switch output 3 and
     input 1.)
q    Intermittent operation INT VOLUME 2: ON (Continuity exists between combination switch output 5 and
     input 1.)
q    Intermittent operation INT VOLUME 3: ON (Continuity exists between combination switch output 4 and
     input 2.)
BCM determines front wiper intermittent operation delay interval from wiper Intermittent dial position and vehi-
cle speed, and sends wiper request signal (INT) to IPDM E/R.
AUTO STOP OPERATION
With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When the wiper arms are not located at base of windshield with wiper switch OFF, ground is provided
q   from IPDM E/R terminal 21
q   to front wiper motor terminal 3, in order to continue wiper motor operation at low speed,
q   to IPDM E/R terminal 32
q   through front wiper motor terminals 4 and 2
q   through grounds E17 and E43.
When the wiper arms reach base of windshield, front wiper motor terminals 4 and 2 are connected, and
ground is supplied
Then the IPDM E/R sends auto stop operation signal to BCM with CAN communication line.
When the BCM receives auto-stop operation signal, BCM sends wiper stop signal to IPDM E/R with CAN com-
munication line.
IPDM E/R stops wiper motor. Wiper motor will then stop wiper arms at the STOP position.
WASHER OPERATION
When the wiper switch is in front wiper washer position, BCM detect front wiper washer signal by BCM wiper
switch reading function. (Refer to WW-7, "COMBINATION SWITCH READING FUNCTION" )
Combination switch ground is supplied
q   to front washer pump terminal 1
q   through combination switch terminal 11
q   through combination switch terminal 12
q   through grounds M30 and M66.
With ground is supplied, front washer pump is operated.
When the BCM detects that front washer pump has operated for 0.4 seconds or longer, BCM operates front
wiper motor for low speed.
When the BCM detects washer switch is OFF, low speed operation cycles approximately 2 times and stops.

                             FRONT WIPER AND WASHER SYSTEM

MIST OPERATION
When the wiper switch is turned to the mist position, wiper low speed operation cycles once and then stops.              A
For additional information about wiper operation under this condition, refer to WW-5, "LOW SPEED WIPER
OPERATION" .
If switch is held in mist position, low speed operation continues.                                                       B
FAIL-SAFE FUNCTION
If an abnormality occurs in CAN communications, IPDM E/R holds the condition just before fail-safe status is
initiated until ignition switch is turned OFF. (If wipers were operating in LO just before the initiation of fail-safe   C
status, they continue to operate in LO until ignition switch is turned OFF.)
COMBINATION SWITCH READING FUNCTION
                                                                                                                         D
Description
q   BCM reads combination switch (wiper) status, and controls related systems such as headlamps and wip-
    ers, according to the results.
                                                                                                                         E
q   BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)
    and five input terminals (INPUT 1-5).
Operation Description                                                                                                    F
q   BCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in
    turn.
q   If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals              G
    (INPUT 1-5) becomes active.
q   At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
    age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-              H
    age change, and BCM determines that switch is ON.

BCM - Operation Table of Combination Switches
q   BCM reads operation status of combination switch using combinations shown in table below.




                                                                                                 SKIA8640E


Sample Operation: (When Wiper Switch Turned to LOW Position)
q   When wiper switch is turned to LOW position, front wiper LOW contact in combination switch turns ON. At
    this time if OUTPUT 1 transistor is activated, BCM detects that voltage changes in INPUT 3.
q   When BCM detects that voltage changes in INPUT 3 while OUTPUT 1 transistor is ON, it judges that front
    wiper switch is in LOW position. Then BCM sends front wiper request signal (LO) to IPDM E/R using CAN
    communication.
q   If BCM detects that voltage changes in INPUT 3 when OUTPUT 1 transistor is activated again, it recog-
    nizes that wiper switch is still in LOW position.

                             FRONT WIPER AND WASHER SYSTEM

NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-              A
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.
Operation Mode                                                                                                              B
Combination switch reading function has operation modes shown below.
1. Normal status
   q When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.
                                                                                                                            C
2. Sleep status
   q When BCM is in sleep status, transistors of OUTPUT (1 and 5) stop the output, and BCM enters low
                                                                                                                            D

Intermittent Operation
Wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent opera-
tion dial position 1, intermittent operation dial position 2, and intermittent operation dial position 3) and vehicle
speed signal.
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
CAN Communication System Description                                                                             NKS000Z7


CAN (Controller Area Network) is a serial communication line for real time application. It is an on-board multi-
plex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication Unit                                                                                           NKS000Z8
