 PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” EKS00860

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
● 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.
● 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.
● 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.
Wiper and Washer System EKS007AW

● If snow or other obstacle stops wipers from moving while front wipers are operating, wipers will stop mov-
ing to protect motor. In this case, turn the switch OFF and remove obstacle. Wait at least 20 seconds
before turning the switch ON again to start front wipers.
● If rear wiper operation is stopped 5 seconds or more due to snow or other reason, the BCM stops rear
wiper operation to protect motor. At this time, after removing cause of stoppage, turn rear wiper switch to
OFF, wait at least 1 min, then turn wiper switch to ON or INT to restart wiper.
● The hood may be scratched if opened while front wipers are locked back.
● If there is unevenness or peeling of windshield glass wax, other oil films, or glass coating, wipers may not
wipe correctly (juddering or other non-standard conditions may occur).
● Washer pump may malfunction if operated continuously for 1 minute or longer.

WIPER OPERATION
Low Speed Wiper Operation
When front wiper switch is placed in LO position, BCM read combination switch condition (Refer to WW-8,
"BCM WIPER SWITCH READING FUNCTION" ). And BCM sent front wiper request signal (LO) to IPDM E/R
with CAN communication line. When IPDM E/R receives front wiper request signal (LO), it turns ON front
wiper main relay (built into IPDM E/R).
Power is supplied
● to front wiper motor terminal 3,
● through front wiper main relay and front wiper HI/LO relay and
● through IPDM E/R terminal 23.
Ground is supplied
● to front wiper motor terminal 1,
● through body grounds E25 (CR engine models), E26 and E40.
With power and ground are supplied, the front wiper motor operates at low speed.
High Speed Wiper Operation
When front wiper switch is placed in HI position, BCM read combination switch condition (Refer toWW-8,
"BCM WIPER SWITCH READING FUNCTION" ).And BCM sent front wiper request signal (HI) to IPDM E/R
with CAN communication line.When IPDM E/R receives front wiper request signal (HI), it turns ON front wiper
HI/LO relay and front wiper main relay (built into IPDM E/R).
Power is supplied
● to front wiper motor terminal 2,
● through front wiper main relay and front wiper HI/LO relay and,
● through IPDM E/R terminal 24.
Ground is supplied
● to front wiper motor terminal 1
● through body grounds E25, E26 and E40.
With power and ground are supplied, the front wiper motor operates at high speed.
Intermittent Operation
When front wiper switch is placed in INT position, BCM read combination switch condition (refer to WW-8,
"BCM WIPER SWITCH READING FUNCTION" ) and it operates as follows.
● BCM reads combination switch condition of V/INT 1, 2 and 3, it determines INT volume.(Refer to WW-8,
"BCM WIPER SWITCH READING FUNCTION" )
● BCM receives vehicle speed signal from combination meter with CAN communication line.
● BCM calculates intermittent interval from INT volume and vehicle speed signal.
● BCM sends front wiper request signal to IPDM E/R for every intermittent interval via CAN communication
line.
Power is supplied
● to front wiper motor terminal 3,
● through front wiper main relay and front wiper HI/LO relay and
● through IPDM E/R terminal 23.

WW-6
 FRONT WIPER AND WASHER SYSTEM

Auto Stop Operation

With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach stop position. A
When wiper arms are not located at stop position with wiper switch OFF, power is supplied
● from terminal 23 of the IPDM E/R
● to front wiper motor terminal 3, in order to continue wiper motor operation at low speed. B
Ground is supplied
● to front wiper motor terminal 1
C
● through body grounds E25 (CR engine models), E26 and E40.
When wiper arms reach stop position, front wiper motor terminals 1 and 4 are connected.
Then the IPDM E/R sends auto stop operation signal to BCM with CAN communication line.
D
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.
E
Mist Operation
When the wiper switch is placed in the mist position, wiper operate ones. The wiper operation is the same as
the front wiper low speed operation. If the switch is held in the mist position, front wiper low speed operation
continues. F

WASHER OPERATION
When front wiper switch is pulled to washer position, power is supplied G
● through combination switch terminal 13
● to washer motor terminal 1.
Ground is supplied H
● to washer motor terminal 2
● through combination switch terminals 12 and 14, and
● through body grounds M19 and M20. I
With power and ground supplied, the washer motor operates, and at the same time,
When the wiper switch is pulled to the WASH position for 1 second or more. BCM sends front wiper request
signal (low) to IPDM E/R with CAN communication line. And the front wiper motor operates at low speed for J
approximately 3 times to clean wind shield
FAIL-SAFE FUNCTION
WW
When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control. If the
fail-safe system is operating, front wiper low speed operates when the ignition switch is turned from OFF to
ON or ACC and front wiper are stopped when the ignition switch is turn from ON or ACC to OFF. If the fail-safe
system is operating, front wiper does not operate when the combination switch is in any position. After CAN L
communication recovers normally, it also returns to normal control. (Refer to PG-19, "FAIL-SAFE FUNCTION"
)

WW-7
 FRONT WIPER AND WASHER SYSTEM

BCM WIPER SWITCH READING FUNCTION

BCM reads combination switch (wiper switch) status, and controls front wipers based on the results.
BCM is a combination of 5 output terminals (output 1 - 5) and 5 input terminals (input 1 - 5). It reads 20 types
of switch data and 5 types of diagnosis data.

MKIB0369E

Operation Description
● BCM operates output terminal (output 1 to 5) transistor at a set period and turns ON the current in order.
● When any (or multiple) switches are turned ON, a circuit is formed between the output terminals (output 1
to 5) and input terminals (input 1 to 5).
● At this time, when output terminals (output 1 to 5) operate transistors and carry current. If voltage of corre-
sponding input terminal (input 1 to 5) changes, interface in BCM detects this state and judges that switch
is ON.
Table Of BCM - Combination Switch Operations
BCM reads operation status of combination switch using combinations shown in table below.

MKIB0370E

WW-8
 FRONT WIPER AND WASHER SYSTEM

Example: (Wiper Switch Placed In LO Position)

● If front wiper switch is placed in LO position, the contact of front wiper LO in combination switch is turned A
ON. At this time, when output 1 transistor operates, driver control unit detects that voltage has been
changed at input 3.
● When output 1 transistor is ON and BCM detects current changes at input 3, BCM determines that wiper B
switch is at LO. BCM uses CAN communication and sends front wiper signals to IPDM E/R.
● When output 1 transistor operates again and BCM detects voltage change at input 3, BCM recognizes
that front wiper LO operation is continuing. C

MKIB0468E
I
NOTE:
Each output terminal transistor operates at 20 ms intervals. Therefore, after a switch is turned ON, the
electrical loads are activate with a time delay, However, this delay is too small to be detected.
J
Intermittent Operation
Wiper intermittent operation delay interval is determined from a combination of 3 switches (V/INT 1, V/INT 2,
and V/INT 3) and vehicle speed signal. WW
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
Wiper Volume Position Setting
Combination switch
L
Wiper dial position Intermittent interval
V/INT 1 V/INT 2 V/INT 3
Wiper volume position 1 ON ON ON
Small M
Wiper volume position 2 ON ON OFF
Wiper volume position 3 ON OFF OFF
Wiper volume position 4 ↓ OFF OFF OFF
Wiper volume position 5 OFF OFF ON
Wiper volume position 6 OFF ON ON
Large
Wiper volume position 7 OFF ON OFF

Example: For wiper volume position 1...

Using combination switch reading function, BCM reads ON/OFF status of V/INT 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper volume position 1.
● V/INT 1: ON (input 1 and output 3 are performing.)
● V/INT 2: ON (input 1 and output 5 are performing.)
● V/INT 3: ON (input 2 and output 4 are performing.)
BCM determines front wiper intermittent interval from wiper volume 1 and vehicle speed, and sends wiper
request signal (INT) to IPDM E/R for every intermittent interval via CAN communication line.

CAN Communication EKS00K7O

SYSTEM DESCRIPTION
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.

● to combination switch terminal 12
● to rain sensor terminal 3, and C
● to BCM terminals 2 and 70
WIPER OPERATION
Low Speed Wiper Operation D
When front wiper switch is placed in LO position, BCM read combination switch condition (Refer toWW-51,
"BCM WIPER SWITCH READING FUNCTION" ). And BCM sent front wiper request signal (LO) to IPDM E/R
with CAN communication line. When IPDM E/R receives front wiper request signal (LO), it turns ON front E
wiper main relay (built into IPDM E/R).
Power is supplied
● to front wiper motor terminal 3, F
● through front wiper main relay and front wiper HI/LO relay and
● through IPDM E/R terminal 23.
Ground is supplied G
● to front wiper motor terminal 1,
● through body grounds E25 (CR engine models), E26 and E40.
H
With power and ground are supplied, the front wiper motor operates at low speed.
High Speed Wiper Operation
When front wiper switch is placed in HI position, BCM read combination switch condition (Refer toWW-51, I
"BCM WIPER SWITCH READING FUNCTION" ). And BCM sent front wiper request signal (HI) to IPDM E/R
with CAN communication line. When IPDM E/R receives front wiper request signal (HI), it turns ON front wiper
HI/LO relay and front wiper main relay (built into IPDM E/R).
J
Power is supplied
● to front wiper motor terminal 2,
● through front wiper main relay and front wiper HI/LO relay and, WW
● through IPDM E/R terminal 24.
Ground is supplied
● to front wiper motor terminal 1 L
● through body grounds E25 (CR engine models), E26 and E40.
With power and ground are supplied, the front wiper motor operates at high speed.
M
Auto Wiper Operation
When the wiper switch is placed in the INT position, the wiper does not operate until rain sensor perceives
rain.
When rain sensor detection of rain drop, rain sensor send rain signal to BCM
● from rain sensor terminal 2
● to BCM terminal 63.
BCM send wiper request signal to IPDM E/R with CAN communication line. IPDM E/R operate front wiper.
Change the wiper speed by rainfall.
The rain sensor sensitivity is controlled by the wiper volume switch combined with front wiper and washer
switch and BCM.
Auto Stop Operation
With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach stop position.
When wiper arms are not located at stop position with wiper switch OFF, power is supplied
● from terminal 23 of the IPDM E/R
● to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
Ground is supplied
WW-49
 FRONT WIPER AND WASHER SYSTEM (WITH RAIN SENSOR)

● to front wiper motor terminal 1

● through body grounds E25 (CR engine models), E26 and E40.
When wiper arms reach stop position, front wiper motor terminals 1 and 4 are disconnected.
Then the 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.
Mist Operation
When the wiper switch is placed in the mist position, wiper operate ones.The wiper operation is the same as
the front wiper low speed operation.If the switch is held in the mist position, front wiper low speed operation
continues.
WASHER OPERATION
When front wiper switch is pulled to washer position, power is supplied
● through combination switch terminal 13
● to washer motor terminal 1.
Ground is supplied
● to washer motor terminal 2
● through combination switch terminals 12 and 14, and
● through body times M19 and M20.
With power and ground supplied, the washer motor operates, and at the same time,
When the wiper switch is pulled to the WASH position for 1 second or more. BCM sends front wiper request
signal (low) to IPDM E/R with CAN communication line. And the front wiper motor operates at low speed for
approximately 3 times to clean wind shield
FAIL-SAFE FUNCTION
When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control. If the
fail-safe system is operating, front wiper low speed operates when the ignition switch is turned from OFF to
ON or ACC and front wiper are stopped when the ignition switch is turn from ON or ACC to OFF. If the fail-safe
system is operating, front wiper does not operate when the combination switch is in any position. After CAN
communication recovers normally, it also returns to normal control.(Refer to PG-19, "FAIL-SAFE FUNCTION"
)

 FRONT WIPER AND WASHER SYSTEM (WITH RAIN SENSOR)

BCM WIPER SWITCH READING FUNCTION

BCM reads combination switch (wiper switch) status, and controls front wipers based on the results. A
BCM is a combination of 5 output terminals (output 1 - 5) and 5 input terminals (input 1 - 5). It reads 20 types
of switch data and 5 types of diagnosis data.
B

MKIB0369E

Operation Description H
● BCM operates output terminal (output 1 to 5) transistor at a set period and turns ON the current in order.
● When any (or multiple) switches are turned ON, a circuit is formed between the output terminals (output 1
to 5) and input terminals (input 1 to 5). I
● At this time, when output terminals (output 1 to 5) operate transistors and carry current. If voltage of corre-
sponding input terminal (input 1 to 5) changes, interface in BCM detects this state and judges that switch
is ON. J
Table Of BCM - Combination Switch Operations
BCM reads operation status of combination switch using combinations shown in table below.
WW

MKIB0370E

WW-51
 FRONT WIPER AND WASHER SYSTEM (WITH RAIN SENSOR)

Example: (Wiper Switch Placed In LO Position)

● If front wiper switch is placed in LO position, the contact of front wiper LO in combination switch is turned
ON. At this time, when output 1 transistor operates, driver control unit detects that voltage has been
changed at input 3.
● When output 1 transistor is ON and BCM detects current changes at input 3, BCM determines that wiper
switch is at LO. BCM uses CAN communication and sends front wiper signals to IPDM E/R.
● When output 1 transistor operates again and BCM detects voltage change at input 3, BCM recognizes
that front wiper LO operation is continuing.

MKIB0468E

NOTE:
Each output terminal transistor operates at 20 ms intervals. Therefore, a delay occurs between the switch
becoming ON and operation of the electric load. However, this delay is too small to be detected.
Intermittent Operation
Wiper intermittent operation delay interval is determined from a combination of 3 switches (V/INT 1, V/INT 2,
and V/INT 3) and vehicle speed signal.
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
Wiper Volume Position Setting
Combination switch
Wiper dial position Intermittent interval
V/INT 1 V/INT 2 V/INT 3
Wiper volume position 1 ON ON ON
Small
Wiper volume position 2 ON ON OFF
Wiper volume position 3 ON OFF OFF
Wiper volume position 4 ↓ OFF OFF OFF
Wiper volume position 5 OFF OFF ON
Wiper volume position 6 OFF ON ON
Large
Wiper volume position 7 OFF ON OFF

Example: For wiper volume position 1.

Using combination switch reading function, BCM reads ON/OFF status of V/INT 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper volume position 1.
● V/INT 1: ON (input 1 and output 3 are conducting.)
● V/INT 2: ON (input 1 and output 5 are conducting.)
● V/INT 3: ON (input 2 and output 4 are conducting.)
BCM determines front wiper intermittent interval from wiper volume 1 and vehicle speed, and sends wiper
request signal (INT) to IPDM E/R for every intermittent interval via CAN communication line.

CAN Communication EKS00K7Q

SYSTEM DESCRIPTION A
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 B
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.

System Description EKS0087F

● Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM when switch is turned ON.
● BCM controls rear wiper and INT (intermittent) operation.
Power is supplied at all times
● through 40A fusible link (letter J, located in fuse and fusible link box)
● to BCM terminals 74 and 79.
When ignition switch turned ON or START position, power is supplied
● through 10A fuse [No. 4 located in the fuse block (J/B)]
● to BCM terminal 24.
● through 15A fuse [No. 1 located in the fuse block (J/B)]
● to combination switch terminal 11.
Ground is supplied
● through body grounds M19 and M20
● to BCM terminals 2 and 70, and
● to combination switch terminal 12.
● through body ground B17, B23, B44 and B51
● to rear wiper motor terminal 3.
WIPER OPERATION
BCM read combination switch condition (Refer to WW-83, "BCM WIPER SWITCH READING FUNCTION" ),
Power is supplied
● through BCM terminal 71
● to rear wiper motor terminal 1.

WW-82
 REAR WIPER AND WASHER SYSTEM

Ground is supplied
● to rear wiper motor terminal 3 A
● through body grounds B17, B23, B44 and B51.
With power and ground supplied, the rear wiper motor operates.
B
INTERMITTENT OPERATION
The rear wiper motor operates the wiper arms at low speed of approximately every 7 seconds. This feature is
controlled by the BCM. C
When rear wiper switch is placed in INT position, BCM read combination switch condition (Refer to WW-83,
"BCM WIPER SWITCH READING FUNCTION" ), power is supplied.
● through BCM terminal 71.
D
● to rear wiper motor terminal 1
Ground is supplied.
● to rear wiper motor terminal 3 E
● through body ground B17, B23, B44 and B51.
The wiper motor operates at intermittent.
WASHER OPERATION F
When rear wiper switch is pushed to WASH position,
Power is supplied.
G
● through combination switch terminal 14
● to washer motor terminal 2.
Ground is supplied H
● to washer motor terminal 1
● to combination switch terminals 12 and 13, and
● through grounds M19 and M20. I
With power and ground supplied, the rear washer motor is operated, and at the same time,
When the wiper switch is pushed to the WASH position for 1 second or more, BCM reads combination switch
condition (Refer to WW-83, "BCM WIPER SWITCH READING FUNCTION" ), rear wiper motor is operated by J
BCM, and the rear wiper motor operates approximately 3 times after wiper switch is released.
BCM WIPER SWITCH READING FUNCTION
BCM reads combination switch (wiper switch) status, and controls rear wipers based on the results. WW
BCM is a combination of 5 output terminals (output 1 - 5) and 5 input terminals (input 1 - 5). It reads 20 types
of switch data and 5 types of diagnosis data.

MKIB0369E

WW-83
 REAR WIPER AND WASHER SYSTEM

Operation Description
● BCM operates output terminal (output 1 to 5) transistor at a set period and turns ON the current in order.
● When any (or multiple) switches are turned ON, a circuit is formed between the output terminals (output 1
to 5) and input terminals (input 1 to 5).
● At this time, when output terminals (output 1 to 5) operate transistors and carry current. If voltage of corre-
sponding input terminal (input 1 to 5) changes, interface in BCM detects this state and judges that switch
is ON.
Table of BCM - Combination Switch Operations
BCM reads operation status of combination switch using combinations shown in table below.

MKIB0370E

Sample Operation: (Rear Wiper Switch Placed In LO Position)

● If rear wiper switch is turned to ON position, the contact of rear wiper ON in combination switch is turned
ON. At this time, when output 5 transistor operates, driver control unit detects that voltage has been
changed at input 2.
● When output 5 transistor is ON and BCM detects current changes at input 2, BCM determines that wiper
switch is at ON.

WW-84
 REAR WIPER AND WASHER SYSTEM

● When output 5 transistor operates again and BCM detects voltage change at input 2, BCM recognizes
that rear wiper ON operation is continuing. A

MKIB0497E
G
NOTE:
Each OUTPUT terminal transistor is activate at 20 ms intervals. Therefore, after a switch is turned ON,
electrical loads are activated with a time delay, However, this delay is so small it is undetectable.

CAN Communication EKS00K7S

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

System Description EKS0087R

● Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM when switch is turned ON.
● BCM controls headlamp washer operation.
● IPDM E/R operates headlamp washer motor according to CAN communication signals from BCM.
Power is supplied at all times
● through 30 A fusible link (letter L, located in fuse and fusible link box).
● to headlamp washer relay terminals 1 and 3.
● through 40 A fusible link (letter J, located in fuse and fusible link box).
● to BCM terminals 74 and 79.
● through 20 A fuse (NO.52, located in IPDM E/R).
● to IPDM E/R (CPU).
When ignition switch ON or START position, power is supplied
● to IPDM E/R (CPU), and
● through 10 A fuse [NO.4, located in fuse block (J/B)]
● to BCM terminal 24.
Ground is supplied
● to IPDM E/R terminals 3 and 54, and
● to head lamp washer motor terminal 1,
● through body grounds E25 (CR engine models), E26 and E40.
● to BCM terminals 2 and 70, and
● to head lamp washer switch terminal 2,
● through body grounds M19 and M20.
HEADLAMP WASHER OPERATION
When lighting switch is placed in 1st position, BCM read combination switch condition (Refer to WW-83, "BCM
WIPER SWITCH READING FUNCTION" ).
And headlamp washer switch ON, ground is supplied.
