PRECAUTION
PRECAUTION PFP:00011
A
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.
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 AKS003RE
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.

vehicle speeds, this feature is controlled by BCM and IPDM E/R.
When front wiper switch is in HI position BCM detect high speed wiper ON signal by BCM wiper switch reading
function. BCM performs the following operations
Revision: 2004 December WW-5 2004.5 350Z
FRONT WIPER AND WASHER SYSTEM
q When BCM detects ON/OFF status of intermittent operation dial positions 1, 2, and 3 it determines wiper
dial position status. Refer to WW-9, "Wiper Dial Position Setting" .
q BCM calculates operation interval from wiper dial position and vehicle speed signal received from combi-
nation meter with CAN communications.
q BCM sends front wiper request signal (INT) to IPDM E/R at calculated operation interval.
q When IPDM E/R receives front wiper request signal (INT), it turns ON internal front wiper relay. It then
sends auto-stop signal to BCM, and conducts intermittent front wiper operation.
With power and ground is supplied, rear wiper operates at intermittent.
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, E43 and F152.
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 STOP position.
WASHER OPERATION
When wiper switch is in front wiper washer position, BCM detect front wiper washer signal by BCM wiper
switch reading function. (Refer to WW-6, "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 is 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 switch is held in mist position, low speed operation continues.
FAIL-SAFE FUNCTION
IPDM E/R includes a fail-safe function to prevent malfunction of electrical components controlled by CAN com-
munications in CAN communications occurs.
When fail-safe status is initiated, IPDM E/R remains in steady unit signals are received.
COMBINATION SWITCH READING FUNCTION
Description
q BCM reads combination switch (wiper) status, and controls related systems such as head lamps and wip-
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).
Revision: 2004 December WW-6 2004.5 350Z
FRONT WIPER AND WASHER SYSTEM
Operation Description
q BCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in A
turn.
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. B
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-
age change, and BCM determines that switch is ON. C

Revision: 2004 December WW-7 2004.5 350Z
FRONT WIPER AND WASHER SYSTEM
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.
PKIA7243E
NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.
Operation Mode
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.
2. Sleep status
Revision: 2004 December WW-8 2004.5 350Z
FRONT WIPER AND WASHER SYSTEM
q When BCM is in sleep status, transistors of OUTPUT (1 and 5) stop the output, and BCM enters low
current consumption mode. OUTPUT (2, 3, and 4) turn ON-OFF every 10 ms, and only input from light A
switch system is accepted.

Intermittent Operation J
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. WW
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.

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 (input 3 and output 1 are conducting.)
q Intermittent operation dial position 2: ON (input 5 and output 1 are conducting.)
q Intermittent operation dial position 3: ON (input 4 and output 2 are conducting.)
Revision: 2004 December WW-9 2004.5 350Z
FRONT WIPER AND WASHER SYSTEM
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.
CAN Communication System Description AKS000Y8
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.
CAN Communication Unit AKS003M9
Refer to LAN-5, "CAN Communication Unit" .
