PRECAUTION
PRECAUTION PFP:00011
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS0094G
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. 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
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:
G 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.
G 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.
G 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.

System Description EKS0094J
G Both front wiper relays are located in the IPDM E/R (intelligent power distribution module engine room).
G 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 (body control module) when switch is turned ON.
G BCM controls front wiper LO, HI, and INT (intermittent) operation.
G IPDM E/R operates wiper motor according to CAN communication signals from the BCM.
Power is supplied at all times

G to ignition relay, located in the IPDM E/R, and

Ground is supplied
G to BCM terminal 67, and
G to combination switch terminal 12
G through grounds M57, M61 and M79, and
G to IPDM E/R terminals 38 and 60, and
G to front wiper motor terminal E
G through grounds E15 and E24.
LOW SPEED WIPER OPERATION
When the ignition switch is in the ON or START position, and the front wiper switch is turned to low position,
the BCM detects a low speed wiper ON signal by BCM wiper switch reading function.
BCM then sends front wiper (low) request signal over CAN communication lines
G from BCM terminals 39 and 40
G to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper (low) request signal, it supplies ground to energize the front wiper relay.
With the front wiper relay energized, power is supplied
G through front wiper relay
G to front wiper high relay
G through IPDM E/R terminal 21
G to front wiper motor terminal L.
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 high position,
the BCM detects a high speed wiper ON signal by BCM wiper switch reading function.
BCM then sends front wiper (high) request signal over CAN communication lines
G from BCM terminals 39 and 40
G to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper (high) request signal, it supplies ground to energize the front wiper and
the front wiper high relays.
With the front wiper and the front wiper high relays energized, power is supplied
G through front wiper relay
G to front wiper high relay
G through IPDM E/R terminal 31
G to front wiper motor terminal H.
With power and ground supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Wiper intermittent operation delay interval is determined from the combination of the intermittent wiper dial
position inputs and vehicle speed. During each intermittent operation delay interval, the BCM sends a front
wiper request signal to the IPDM E/R to operate the wipers.
Revision: May 2006 WW-4 2007 Maxima
FRONT WIPER AND WASHER SYSTEM
When the ignition switch is in ON or START position, and the front wiper switch is turned to intermittent posi-
tion, the BCM detects a front wiper (intermittent) ON signal by BCM wiper switch reading function. A
BCM then sends front wiper (intermittent) request signal over CAN communication lines
G from BCM terminals 39 and 40
G to IPDM E/R terminals 48 and 49. B
When BCM determines that combination switch status is front wiper intermittent ON, it performs the following
operations.
G BCM detects ON/OFF status of intermittent wiper dial position C
G BCM calculates operation interval from wiper dial position and vehicle speed signal received from unified
meter and A/C amp. through CAN communications.
G BCM sends front wiper request signal (INT) to IPDM E/R at calculated operation interval. D
When IPDM E/R receives front wiper request signal (INT), it supplies ground to energize the front wiper relay.
It then sends auto-stop signal to BCM and conducts intermittent front wiper motor operation.
E
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 windshield base. When wiper arms reach base
of windshield, front wiper motor terminals P and E are connected. F
Ground is supplied
G to IPDM E/R terminal 32
G through front wiper motor terminal P G
G through front wiper motor terminal E
G through grounds E15 and E24.
H
The IPDM E/R sends auto stop operation signal to BCM through CAN communication lines.
When BCM receives auto stop operation signal, BCM sends wiper stop signal to IPDM E/R with CAN commu-
nication lines. The IPDM E/R then de-energizes the front wiper relay.
Wiper motor will then stop wiper arms at the STOP position. I
WASHER OPERATION
When wiper switch is in front wiper washer position, BCM detects front wiper washer signal by BCM wiper J
switch reading function. Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
When the ignition switch is in ON or START position, power is supplied
G through 10A fuse (No. 47, located in the IPDM E/R)
