Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS00N1N
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:
lTo 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.
lImproper 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.
lDo 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.

lthrough grounds E21, E41 and E61.
LOW SPEED WIPER OPERATION
When the ignition switch is in the ON or START position, and the front wiper switch is turned to the low posi-
tion, the BCM detects a low speed wiper ON request through the combination switch (wiper switch) reading
function.
The BCM then sends a front wiper (low) request signal with CAN communication.
lfrom BCM terminals 21 and 22
lto IPDM E/R terminals 39 and 40.
When IPDM E/R receives front wiper (low) request signal, it supplies ground to energize the front wiper main
relay.
With the front wiper LOW/ HIGH relay energized, power is supplied
lthrough front wiper main relay
lthrough front wiper LOW/HIGH relay
lthrough IPDM E/R terminal 32
lto front wiper motor terminal 1.
Ground is supplied
lto front wiper motor terminal 2
lthrough grounds E21, E41 and E61.
With power and ground supplied, the front wiper motor operates at low speed.
HI SPEED WIPER OPERATION
When the ignition switch is in the ON or START position, and the front wiper switch is turned to the high posi-
tion, the BCM detects a high speed wiper ON request through the combination switch (wiper switch) reading
function.
The BCM then sends a front wiper (high) request signal with CAN communication.
lfrom BCM terminals 21 and 22
lto IPDM E/R terminals 39 and 40.
When IPDM E/R receives front wiper (high) request signal, it supplies ground to energize the front wiper main
relays.
With the front wiper LOW/HIGH relays energized, power is supplied
lthrough front wiper main relay
lthrough front wiper LOW/HIGH relay
lthrough IPDM E/R terminal 35
lto front wiper motor terminal 4.
Ground is supplied
lto front wiper motor terminal 2
lthrough grounds E21, E41 and E61.
With power and ground supplied, the front wiper motor operates at high speed.

FRONT WIPER AND WASHER SYSTEM
INTERMITTENT OPERATION
When front wiper switch is turned to INT position, wiper performs intermittent operation, low-speed operation,
and high-speed operation according to water drop increase rate on windshield detected by light and rain sen-
sor. If light and rain sensor malfunctions, it operates as vehicle speed sensing wiper during driving and oper-
ates intermittent operation according to INT-volume switch with vehicle stopped. During this time, BCM
controls each operation.
The BCM then sends a front wiper (HI or LOW) request signal with CAN communication.
lfrom BCM terminals 21 and 22
lto IPDM E/R terminals 39 and 40.
When the BCM determines that combination switch status is front wiper intermittent ON, it performs the follow-
ing operations.
lBCM detects intermittent wiper dial position.
lBCM sends front wiper request signal (HI or LOW) to IPDM E/R at calculated operation interval.
When IPDM E/R receives front wiper request signal (HI or LOW), it supplies ground to energize the front wiper
main relay and front wiper LOW/HIGH relay. It then sends an auto-stop signal to the BCM, and conducts inter-
mittent front wiper motor operation.
AUTO STOP OPERATION
When the wiper arms are not located at the base of the windshield, and the wiper switch is turned OFF, the
wiper motor will continue to operate until the wiper arms reach the windshield base. When the wiper arms
reach the base of windshield, front wiper motor terminals 2 and 5 are connected.
Ground is supplied
lto IPDM E/R terminal 43
lthrough front wiper motor terminal 5
lthrough front wiper motor terminal 2
lthrough grounds E21, E41 and E61.
The IPDM E/R sends an auto stop operation signal to the BCM with CAN communication.
When the BCM receives an auto stop operation signal, the BCM sends wiper stop signal to the IPDM E/R over
CAN communication lines. The IPDM E/R then de-energizes the front wiper main relay.
The wiper motor will then stop the wiper arms at the STOP position.
FRONT WASHER OPERATION
When the ignition switch is in the ON or START position, and the front washer switches are OFF, the front
washer motor is supplied power
lthrough 10A fuse [No. 15, located in fuse block (J/B)]
lthrough combination switch (wiper switch) terminal 2
lthrough combination switch (wiper switch) terminal 4
lto front washer motor terminal 1.
When the front wiper switch is in the front washer position, the BCM detects a front washer signal request
through the combination switch (wiper switch) reading function.
Combination switch ground is supplied
lto front washer motor terminal 2
lthrough combination switch (wiper switch) terminal 3
lthrough combination switch (wiper switch) terminal 9
lthrough grounds M21, M80 and M83.
With ground supplied, the front washer motor is operated in the front direction.
When the BCM detects that front washer motor has operated for 0.4 seconds or longer, the BCM uses CAN
communication and sends a wiper request signal to the IPDM E/R for low speed operation of wipers.
When the BCM detects that the washer switch is OFF, low speed operation cycles approximately 3 times and
then stops.

MIST OPERATION
When the wiper switch is temporarily placed in the mist position, wiper low speed operation cycles once and
then stops.
For additional information about wiper operation under this condition, refer toWW-5, "
LOW SPEED WIPER
OPERATION".
If the switch is held in the mist position, low speed operation continues.
FAIL-SAFE FUNCTION
The BCM includes fail-safe function to prevent malfunction of electrical components controlled by CAN com-
munications if a malfunction in CAN communications occurs.
The BCM uses CAN communications to stop output of electrical components it controls.
Until the ignition switch is turned OFF, the front wiper system remains in same status as just before fail-safe
control was initiated. (If wiper was in low speed operation just before fail-safe, it continues low speed operation
until ignition switch is turned OFF.)
When fail-safe status is initiated, the BCM remains in standby until normal signals are received.
When normal signals are received, fail-safe status is canceled.

FRONT WIPER AND WASHER SYSTEM
COMBINATION SWITCH READING FUNCTION
Description
lBCM reads combination switch status, and controls related systems such as headlamps and wipers,
according to the results.
lBCM reads information for a maximum of 20 switches by combining 5 output terminals (OUTPUT 1-5) and
5 input terminals (INPUT 1-5).
Operation Description
lBCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in
turn.
lIf any (1 or more) switches are turned ON, the circuit of output terminals (OUTPUT 1-5) and input termi-
nals (INPUT 1-5) becomes active.
lAt this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of the input terminal (INPUT 1-5) corresponding to that switch changes, the interface in the BCM
detects a voltage change, and the BCM determines that the switch is ON.

BCM - Operation Table of Combination Switches
lBCM reads operation status of the combination switch using combinations shown in the table below.
Sample Operation: (When Wiper Switch is Turned ON)
lWhen the wiper switch is turned ON, contact in the combination switch turns ON. At this time if OUTPUT 1
transistor is activated, the BCM detects that voltage changes in INPUT 3.
lWhen the OUTPUT 1 transistor is ON, the BCM detects that voltage changes in INPUT 3, and judges that
front wiper low is ON. Then the BCM sends a front wiper request signal (LO) to the IPDM E/R using CAN
communication.
lWhen OUTPUT 1 transistor is activated again, BCM detects that voltage changes in INPUT 3, and recog-
nizes that the wiper switch is continuously ON.
