Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                           AKS00AC5


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.

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.

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 (Continuity exists between combination switch output 3 and input
     1.)
q    Intermittent operation dial position 2: ON (Continuity exists between combination switch output 5 and input
     1.)
q    Intermittent operation dial position 3: ON (Continuity exists between combination switch output 4 and input
     2.)
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 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 1 and 4
q   through grounds E17, E43 and F152.
When the wiper arms reach base of windshield, front wiper motor terminals 1 and 4 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 motor terminal 1
q   through combination switch terminal 11
q   to combination switch terminal 12
q   through grounds M30 and M66.
With ground is supplied, front washer motor is operated.
When the BCM detects that front washer motor 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.
MIST OPERATION
When the wiper switch is turned to the mist position, wiper low speed operation cycles once and then stops.
Revision: 2005 August                                     WW-6                                                       2005 350Z

For additional information about wiper operation under this condition, refer to WW-5, "LOW SPEED WIPER
OPERATION" .                                                                                                             A
If switch is held in mist position, low speed operation continues.
FAIL-SAFE FUNCTION
If an abnormality occurs in CAN communications, IPDM E/R holds the condition just before fail-safe status is             B
initiated until ignition switch is turned off. (If wipers were operating in LO just before the initiation of fail-safe
status, they continue to operate in LO until ignition switch is turned OFF)

Description
q   BCM reads combination switch (wiper) status, and controls related systems such as headlamps and wip-
                                                                                                                         D
    ers, according to the results.
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).
                                                                                                                         E
Operation Description
q   BCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in
    turn.                                                                                                                F
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-        G
    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.
                                                                                                                         H

                                                                                                 PKIA7242E


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
     current consumption mode. OUTPUT (2, 3, and 4) turn ON-OFF every 60 ms, and only input from light
     switch system is accepted.

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex 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.
