Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                           AKS00AIK


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.
                                                                                                                         G
Precautions for Battery Service                                                                              AKS00AUR


Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the                H
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

With power and ground supplied, the front wiper motor operates at low speed.
HI SPEED WIPER OPERATION
When wiper switch is in HI position, BCM detects high speed wiper ON signal by BCM wiper switch reading                 L
function.
BCM sends front wiper request signal (HI) with CAN communication line
q   from BCM terminals 39 and 40                                                                                        M

Example: For wiper dial position 1...
Using combination switch reading function, BCM detects ON/OFF status of intermittent operation dial posi-
tions 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper dial position 1.
q    Intermittent operation dial position 1: ON (Combination switch output 3 and input 1 are performing.)
q    Intermittent operation dial position 2: ON (Combination switch output 5 and input 1 are performing.)
q    Intermittent operation dial position 3: ON (Combination switch output 4 and output 2 are performing.)
BCM determines front wiper intermittent operation delay interval from wiper dial position 1 and vehicle 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 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.
When wiper arms reach base of windshield, front wiper motor terminals 1 and 4 are connected,
and ground is supplied
q   to IPDM E/R terminal 32
q   through front wiper motor terminals 1 and 4
q   through grounds E17 and E43.
Then IPDM E/R sends auto stop operation signal to BCM with CAN communication line.
When BCM receives auto-stop operation signal, BCM sends wiper stop signal to IPDM E/R with CAN commu-
nication line.
IPDM E/R stops wiper motor. Wiper motor will then stop wiper arms at the STOP position.
WASHER OPERATION
When wiper switch is in front wiper washer position with ignition switch on, BCM detects front wiper switch is
on the washer position by BCM wiper switch reading function. (Refer to WW-7, "COMBINATION SWITCH
READING FUNCTION" .) Combination switch (wiper switch) ground is supplied
q   to front washer motor terminal 1
q   through combination switch (wiper switch) terminal 11
q   to combination switch (wiper switch) terminal 12
q   through grounds M30 and M66.
With ground supplied, front washer motor is operated.
When BCM detects that front washer motor has operated for 0.4 seconds or linger, BCM operates front wiper
motor for low speed.
When BCM detects washer switch is OFF, low speed operation cycles approximately 3 times and stops.
MIST OPERATION
When wiper switch is turned to 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 MIST position, low speed operation continues.

Description
q   BCM reads combination switch (wiper) status, and controls related systems such as head lamps and wip-
    ers, according to the results.                                                                                  C
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).
                                                                                                                    D
Operation Description
q   BCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in
    turn.                                                                                                           E
q   If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals
    (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-   F
    age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-
    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 ON)
q   When wiper switch is turned ON, contact in combination switch turns ON. At this time if OUTPUT 1 tran-
    sistor is activated, BCM detects that voltage changes in INPUT 3.
q   When OUTPUT 1 transistor is ON, BCM detects that voltage changes in INPUT 3, and judges that front
    wiper low is ON. Then BCM sends front wiper request signal (LO) to IPDM E/R using CAN communica-
    tion.
q   When OUTPUT 1 transistor is activated again, BCM detects that voltage changes in INPUT 3, and recog-
    nizes that wiper switch is continuously ON.

                            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

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.
