PRECAUTION
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612916
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Procedur e without Cowl Top CoverINFOID:0000000001612917
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

FRONT WIPER AND WASHER SYSTEM
FRONT WIPER AND WASHER SYSTEM
Component Parts and Harness Connector LocationINFOID:0000000001328542
System DescriptionINFOID:0000000001328543
 All front wiper relays (HI, LO) are included in IPDM E/R (intelligent power distribution module engine room).
 Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input terminals.
Terminal combination status is read by BCM ( body control module) when switch is turned ON.
 BCM controls front wiper LO, HI, and INT (intermittent) operation.
 IPDM E/R operates wiper motor according to CAN communication signals from BCM.
OUT LINE
Power is supplied at all times
 through 50 A fusible link (letter M, located in fuse, fusible link and relay box.)
 to BCM terminal 55,
 through 15 A fuse [No. 22, located in fuse block (J/B)]
 to BCM terminal 42,
 through 30 A fuse (No. 73, located in IPDM E/R)
 to front wiper relay, located in IPDM E/R,
 through 15 A fuse (No. 78, located in IPDM E/R) and
 through 10 A fuse (No. 71, located in IPDM E/R)
 to CPU located in IPDM E/R.
When the ignition switch is ON or START position, power is supplied
 to ignition relay located in IPDM E/R, from battery direct,
 through 15 A fuse [No. 1, located in fuse block (J/B)]
 to BCM terminal 38,
 through ignition relay, located in IPDM E/R
 to front wiper relay, located in IPDM E/R
 to front wiper high relay, located in IPDM E/R and
 to CPU located in IPDM E/R,
 through 10 A fuse (No. 84, located in IPDM E/R)
 through IPDM E/R terminal 44
 to combination switch terminal 14.
Ground is supplied

 to IPDM E/R terminals 38 and 60
 through grounds E21, E50 and E51,
 to combination switch terminal 12
 through grounds M35, M45 and M85.
LOW SPEED WIPER OPERATION
When wiper switch is in LOW position, BCM detects low speed wiper ON signal by BCM wiper switch reading
function.
BCM sends front wiper request signal (LO) through CAN communication
 from BCM terminals 39 and 40
 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
 through front wiper relay
 through front wiper high relay
 through IPDM E/R terminal 21
 to front wiper motor terminal 1.
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 low speed.
HIGH SPEED WIPER OPERATION
When wiper switch is in HI position, BCM detects high speed wiper ON signal by BCM wiper switch reading
function.
BCM sends front wiper request signal (HI) through CAN communication
 from BCM terminals 39 and 40
 to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper r equest signal (HI), it turns ON front wiper relay (located in IPDM E/R),
power is supplied
 through front wiper relay
 through front wiper high relay
 through IPDM E/R terminal 31
 to front wiper motor terminal 4.
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 det ermined 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-III or display.
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
