SERVICE INFORMATION
PRECAUTION
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005777027
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 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 w hether 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:
• To avoid rendering the SRS inopera tive, 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 incorrect removal and installation of the SRS can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005988552
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK ″ position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
4. Perform the necessary repair operation.

• to CPU (located in IPDM E/R),
• through 10A fuse [No. 6, located in fuse block (J/B)]
• to BCM terminal 38,
• through 15A fuse [No. 4, located in fuse block (J/B)]
• to combination switch terminal 14.
Ground is supplied
• to IPDM E/R terminals 39 and 59, and
• to front wiper motor terminal 2
• through grounds E15 and E24
• to BCM terminal 67, and
• to combination switch terminal 12
• through grounds M57 and M61.
LOW SPEED WIPER OPERATION
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
• from BCM terminals 39 and 40
• 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/
R, power is supplied
• through IPDM E/R terminal 33 and front wiper high relay and front wiper relay
• to front wiper motor terminal 3.
Ground is supplied
• to front wiper motor terminal 2
• through grounds E15 and E24.
With power and ground is supplied, front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION
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
• from BCM terminals 39 and 40
• 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
relay, located in IPDM E/R, power is supplied
• through IPDM E/R terminal 32
• to front wiper motor terminal 5.
Ground is supplied
• to front wiper motor terminal 2
• 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 s ends 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
• from BCM terminals 39 and 40
• 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.
• BCM detects ON/OFF status of intermittent wiper dial position
• BCM calculates operation interval from wiper dial position.
• 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 cont inue to operate until wiper arms reach windshield base.
When the wiper arms are not located at base of wi ndshield with wiper switch OFF, ground is supplied
• from IPDM E/R terminal 33
• 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
• to IPDM E/R terminal 38
• through front wiper motor terminals 4 and 2, and
• 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 wi ll then stop wiper arms at the STOP position.
WASHER OPERATION
When the wiper switch is in front wiper washer positi on, BCM detect front wiper washer signal by BCM combi-
nation switch reading function. Refer to BCS-4, "
System Description" .
Combination switch power is supplied• through combination switch terminal 14
• to washer motor terminal 1.
Ground is supplied• to front washer motor terminal 2
• through combination switch terminal 11, and
• through combination switch terminal 12
• through grounds M57 and M61.
With ground 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 th is condition, refer to "LOW SPEED WIPER OPERA-
TION" .
If switch is held in mist posit ion, 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 we re operating in LO just before the initiation of fail-safe
status, they continue to operate in LO until ignition switch is turned OFF.)
