PRECAUTION
PRECAUTION PFP:00011
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS00ICZ
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
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. E
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. F
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 EKS00I1H
G Front wiper relays (front wiper relay, front wiper high relay) 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 BCM.
OUTLINE
Power is supplied at all times
G to ignition relay, located in IPDM E/R, from battery directly,
G through 40A fusible link (letter g, located in fuse, fusible link and relay box)
G to BCM terminal 70,
G through 30A fuse (No. 39, located in IPDM E/R)
G to front wiper relay located in IPDM E/R
G through 15A fuse (No. 52, located in IPDM E/R), and
G through 20A fuse (No. 53, located in IPDM E/R)
G to CPU located in IPDM E/R.
When ignition switch is in ON or START position, power is supplied
G through ignition relay (located in IPDM E/R)
Revision: June 2006 WW-4 2007 Versa

G to front wiper relay (located in IPDM E/R), and
G to front wiper high relay (located in IPDM E/R) and A
G to CPU (located in IPDM E/R),
G through 10A fuse [No. 6, located in fuse block (J/B)]
B
G to BCM terminal 38,
G through 15A fuse [No. 4, located in fuse block (J/B)]
G to combination switch terminal 14. C
Ground is supplied
G to IPDM E/R terminals 39 and 59 and
G to front wiper motor terminal 2 D
G through grounds E15 and E24,
G to BCM terminal 67
G to combination switch terminal 12 E
G through grounds M57 and M61.
LOW SPEED WIPER OPERATION F
When the front wiper switch is in LO position, the BCM detects the low speed wiper ON signal by means of the
BCM wiper switch reading function.
The BCM sends a front wiper request signal (LO) through the CAN communication line
G
G from BCM terminals 39 and 40
G to IPDM E/R terminals 40 and 41.
When the IPDM E/R receives front wiper request signal (LO), it turns ON front wiper relay, located in IPDM E/ H
R, power is supplied
G through IPDM E/R terminal 33 and front wiper high relay and front wiper relay
G to front wiper motor terminal 3. I
Ground is supplied
G to front wiper motor terminal 2
G through grounds E15 and E24. J
With power and ground is supplied, front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION WW
When the front wiper switch is in HI position, the BCM detects a high speed wiper ON signal by means of the
BCM wiper switch reading function.
The BCM sends a front wiper request signal (HI) through the CAN communication line
L
G from BCM terminals 39 and 40
G to IPDM E/R terminals 40 and 41.
When the IPDM E/R receives front wiper request signal (HI), it turns ON front wiper relay and front wiper high M
relay, located in IPDM E/R, power is supplied
G through IPDM E/R terminal 32
G to front wiper motor terminal 5.
Ground is supplied
G to front wiper motor terminal 2
G through grounds E15 and E24.
With power and ground is supplied, front wiper motor operates at high speed.
INTERMITTENT OPERATION
Wiper intermittent operation delay interval is determined from the intermittent wiper dial position inputs. During
each intermittent operation delay interval, the BCM sends a front wiper request signal to the IPDM E/R to
operate the wipers.
When the ignition switch is in the ON or START position, and the front wiper switch is turned to the intermittent
position, the BCM detects a front wiper (intermittent) ON signal by means of the BCM wiper switch reading
function.
BCM then sends front wiper (intermittent) request signal through the CAN communication lines
Revision: June 2006 WW-5 2007 Versa
FRONT WIPER AND WASHER SYSTEM
G from BCM terminals 39 and 40
G to IPDM E/R terminals 40 and 41.
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
G BCM calculates operation interval from wiper dial position.
G BCM sends a front wiper request signal (INT) to IPDM E/R at calculated operation interval.
When IPDM E/R receives the front wiper request signal (INT), it supplies ground to energize the front wiper
relay. It then sends auto-stop signal to the BCM and conducts intermittent front wiper motor operation.
AUTO STOP OPERATION
With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When the wiper arms are not located at base of windshield with wiper switch OFF, ground is supplied
G from IPDM E/R terminal 33
G to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
When the wiper arms reach base of windshield, front wiper motor terminals 4 and 2 are connected, and
ground is supplied
G to IPDM E/R terminal 38
G through front wiper motor terminals 4 and 2
G through grounds E15 and E24.
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 the wiper switch is in front wiper washer position, BCM detect front wiper washer signal by BCM wiper
switch reading function. Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
Combination switch power is supplied
G through combination switch terminal 14
G to washer motor terminal 1.
Ground is supplied
G to front washer motor terminal 2
G through combination switch terminal 11
G through combination switch terminal 12
G through grounds M57 and M61.
With ground is supplied, front washer motor is operated.
When the BCM detects that front washer motor has operated for 0.4 seconds or longer, BCM operates front
wiper motor for low speed.
When the BCM detects washer switch is OFF, low speed operation cycles approximately 2 times and stops.
MIST OPERATION
When the wiper switch is turned to the 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" .
If switch is held in mist position, low speed operation continues.
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.)
COMBINATION SWITCH READING FUNCTION
Refer to LT-68, "Combination Switch Reading Function" .
