 PRECAUTION

PRECAUTION PFP:00011
A
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” NKS00325

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
● 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
● 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
● 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.

● through grounds E21, E50 and E51,
● to combination switch terminal 12
● through grounds M35, M45 and M85. E

LOW SPEED WIPER OPERATION

When wiper switch is in LOW position, BCM detects low speed wiper ON signal by BCM wiper switch reading F
function.
BCM sends front wiper request signal (LO) with CAN communication line
● from BCM terminals 39 and 40
G
● to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper request signal (LO), it turns ON front wiper relay located in IPDM E/R,
power is supplied
H
● to front wiper motor terminal 1
● through IPDM E/R terminal 21 and front wiper relay and front wiper high relay.
Ground is supplied I
● to front wiper motor terminal 2
● through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at low speed. J

HI SPEED WIPER OPERATION

When wiper switch is in HI position, BCM detects high speed wiper ON signal by BCM wiper switch reading WW
function.
BCM sends front wiper request signal (HI) with CAN communication line
● from BCM terminals 39 and 40
L
● to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper request signal (HI), it turns ON front wiper relay (located in IPDM E/R),
power is supplied
M
● to front wiper motor terminal 4
● through IPDM E/R terminal 31 and front wiper relay and front wiper high relay.
Ground is supplied
● to front wiper motor terminal 2
● through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Front wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent
operation dial position 1, 2, and 3) and vehicle speed signal.
Speed dependent wiper controlled mode can be changed by the function setting of CONSULT-ll or display.
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.

1 Short ON ON ON
2 ON ON OFF
3 ON OFF OFF
↑
4 OFF OFF OFF
↓
5 OFF OFF ON
6 OFF ON ON
7 Long OFF ON OFF

Example: For wiper intermittent dial position 1

Using combination switch reading function, BCM detects ON/OFF status of INT VOLUME 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper intermittent dial position 1.
● INT VOLUME 1: ON (Continuity exists between combination switch output 3 and input 1.)
● INT VOLUME 2: ON (Continuity exists between combination switch output 5 and input 1.)
● 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 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
● from IPDM E/R terminal 21
● to front wiper motor terminal 1, in order to continue wiper motor operation at low speed.
When wiper arms reach base of windshield, front wiper motor terminals 5 and 2 are connected,
and Ground is supplied
● to IPDM E/R terminal 32
● through front wiper motor terminals 5 and 2
● through grounds E21, E50 and E51.
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 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-8, "COMBINATION SWITCH
READING FUNCTION" ), combination switch (wiper switch) ground is supplied
● to combination switch terminal 13
● through front and rear washer pump terminal 1
● to front and rear washer pump terminal 2
● through combination switch terminal 11
● to combination switch terminal 12
● through grounds M35, M45 and M85.
With ground supplied, front and rear washer pump is operated.
When BCM detects that front and rear washer pump 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 2 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" .

 FRONT WIPER AND WASHER SYSTEM

If switch is held in MIST position, low speed operation continues.

A
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
status, they continue to operate in LO until ignition switch is turned OFF.) B

COMBINATION SWITCH READING FUNCTION

Description
● BCM reads combination switch (wiper) status, and controls related systems such as head lamps and wip-
ers, according to the results.
● 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
● BCM activates transistors of output terminals (OUTPUT 1-5) periodically and, and allows current to flow in
turn.
● If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals
(INPUT 1-5) becomes active.
● 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.

BCM - Operation Table of Combination Switches

BCM reads operation status of combination switch using combinations shown in table below. A

SKIA4959E G
Sample Operation: (When Wiper Switch Turned to LOW Position)
● 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. H
● 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. I
● 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-
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
– When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.
2. Sleep status
– When BCM is in sleep status, transistors of OUTPUT 1 and 5 stop the output, and BCM enters low power
mode. Mean while OUTPUT 2, 3, and 4 send out ON signal every 60 ms, and accept input from lighting
switch system.

PKIC4919E

CAN Communication System Description NKS00328

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 NKS00329
