PRECAUTION

PRECAUTION PFP:00011

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”

AKS009J3

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 Manual.

WARNING:

● To avoid renderi n g the SRS inoper a tive, which could increa s e th e ri s k of perso n al i njury or d e ath

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 per-

sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section.

● 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.

Wiring Diagrams and Trouble Diagnosis AKS009J4

When you read Wiring diagrams, refer to the following:

● Refer to GI-14, "How to Read Wiring Diagrams" .

● Refer to PG-3, "POWER SUPPLY ROUTING CIRCUIT" for power distribution circuit.

When you perform trouble diagnosis, refer to the following:

● Refer to GI-10, "How to Follow Trouble Diagnoses" .

● Refer to GI-26, "How to Perform Efficient Diagnosis for an Electrical Incident" .

PKIB3609E

System Description AKS00CNN

● 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 termi-

nals. 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

● to ignition relay, located in IPDM E/R, from battery direct,

● through 50 A fusible link (letter F, located in fuse, fusible link and relay box)

● to BCM terminal 55,

● through 10 A fuse [No.18 located in fuse block (J/B)]

● to BCM terminal 42,

● through 20 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)

● to CPU located in IPDM E/R,

● through 10 A fuse (No.71 located in IPDM E/R)

● to CPU located in IPDM E/R.

FRONT WIPER AND WASHER SYSTEM

When ignition switch is in ON or START position, power is supplied

● 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.1 located in fuse block (J/B)]

● to BCM terminal 38,

● through 10 A fuse (No.84 located in IPDM E/R)

● through IPDM E/R terminal 44

● to front washer motor terminal 2.

Ground is supplied

● to BCM terminal 52

● through grounds M30 and M66,

● to IPDM E/R terminals 38 and 60

● through grounds E17 and E43,

● to combination switch terminal 12

● through grounds M30 and M66.

LOW SPEED WIPER OPERATION

When the front wiper switch is in low position, BCM detect low speed wiper ON signal by BCM wiper switch reading function. BCM sent front wiper request signal (LOW) with CAN communication line

● from BCM terminals 39 and 40

● to IPDM E/R terminals 48 and 49.

When the IPDM E/R receives front wiper request signal (LOW), it turns ON front wiper relay, located in the IPDM E/R, power is supplied

● to front wiper motor terminal 3

● through IPDM E/R terminal 21 and front wiper high relay and front wiper relay.

Ground is supplied

● to front wiper motor terminal 2

● through grounds E17 and E43.

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, BCM detect high speed wiper ON signal by BCM wiper switch reading function. BCM sent front wiper request signal (HI) with CAN communication line

● from BCM terminals 39 and 40

● to IPDM E/R terminals 48 and 49.

When the IPDM E/R receives front wiper request signal (HI), it turns ON front wiper relay, located in IPDM E/ R, power is supplied

● to front wiper motor terminal 5

● through IPDM E/R terminal 31 and front wiper high relay and front wiper relay.

Ground is supplied

● to front wiper motor terminal 2

● through grounds E17 and E43.

with power and ground is supplied, front wiper motor operates at high speed.

INTERMITTENT OPERATION

Front wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent operation dial position 1, 2, and 3) and vehicle speed signal. After each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.

● Intermittent operation dial position 1: ON (Continuity exists between combination switch output 3 and input

1.)

● Intermittent operation dial position 2: ON (Continuity exists between combination switch output 5 and input

1.)

● Intermittent operation dial position 3: ON (Continuity exists between combination switch output 4 and input

2.)

BCM determines front wiper intermittent operation delay interval from wiper dial position 1 and vehicle speed, and sends wiper request signal (INT) to IPDM E/R.

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 provided

● from IPDM E/R terminal 21

● to front wiper motor terminal 3, in order to continue wiper motor operation at low speed,

● to IPDM E/R terminal 32

● through front wiper motor terminals 4 and 2

● through grounds E17 and E43.

When the wiper arms reach base of windshield, front wiper motor terminals 4 and 2 are connected, and ground is supplied 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 communication 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 WW-7, " Combination switch ground is supplied

● to front washer motor terminal 1

● through combination switch terminal 11

● through combination switch terminal 12

● through grounds M30 and M66.

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.

COMBINATION SWITCH READING FUNCTION" )

MIST OPERATION

When the wiper switch is turned to the mist position, wiper low speed operation cycles once and then stops.

FRONT WIPER AND WASHER SYSTEM

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 Description

● BCM reads combination switch (wiper) status, and controls related systems such as headlamps and wip-

ers, according to the results.

● BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)

and five input terminals (INPUT 1-5).

Operation Description

● BCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in

turn.

● If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals

(INPUT 1-5) becomes active.

● At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-

age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects voltage change, and BCM determines that switch is ON.

BCM - Operation Table of Combination Switches

● BCM reads operation status of combination switch using combinations shown in table below.

SKIA8640E

Sample Operation: (When Wiper Switch Turned to LOW Position)

● When wiper switch is turned to LOW position, front wiper LOW contact in combination switch turns ON. At

this time if OUTPUT 1 transistor is activated, BCM detects that voltage changes in INPUT 3.

● When BCM detects that voltage changes in INPUT 3 while OUTPUT 1 transistor is ON, it judges that front

wiper switch is in LOW position. Then BCM sends front wiper request signal (LO) to IPDM E/R using CAN communication.

● If BCM detects that voltage changes in INPUT 3 when OUTPUT 1 transistor is activated again, it recog-

nizes that wiper switch is still in LOW position.

Edition; 2004 September 2005 G35 Sedan

WW-8

Page 16

FRONT WIPER AND WASHER SYSTEM

NOTE:

Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electrical loads are activated with time delay. But this time delay is so short that it cannot be detected by human senses.

Operation Mode

Combination switch reading function has operation modes shown below.

1. Normal status

● When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.

2. Sleep status

● When BCM is in sleep status, transistors of OUTPUT (1 and 5) stop the output, and BCM enters low

current consumption mode. OUTPUT (2, 3, and 4) turn ON-OFF every 60 ms, and only input from light switch system is accepted.

PKIB6124E

Intermittent Operation

Wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent operation dial position 1, intermittent operation dial position 2, and intermittent operation dial position 3) and vehicle speed signal. During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.

CAN Communication System Description AKS009J7

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-board multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

CAN Communication Unit AKS009J8

Balancing Wheels (Bonding Weight Type) AES0002H

REMOVAL

1. Remove inner and outer balance weights from the road wheel.

CAUTION:

Be careful not to scratch the road wheel during removal.

2. Using releasing agent, remove double-faced adhesive tape from the road wheel.

CAUTION:

● Be careful not to scratch the road wheel during removal.

● After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road

wheel.

WHEEL BALANCE ADJUSTMENT

● If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,

select and adjust a drive-in weight mode suitable for road wheels.

1. Set road wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.

2. When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbalance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with a value closest to the calculated value above and install it to the designated outer position of, or at the designated angle in relation to the road wheel.

CAUTION:

● Do not install the inner balance weight before installing the outer balance weight.

● Before installing the balance weight, be sure to clean the

mating surface of the road wheel.

Indicated unbalance value × 5/3 = balance weight to be installed Calculation example: 23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance weight (closer to calculated balance weight value) Note that balance weight value must be closer to the calculated balance weight value. Example:

37.4 = 35 g (1.23 oz)

37.5 = 40 g (1.41 oz)

SMA054D

a. Install balance weight in the position shown in the figure. b. When installing balance weight to road wheels, set it into the

grooved area on the inner wall of the road wheel as shown in the figure so that the balance weight center is aligned with the wheel balancer indication position (angle).

CAUTION:

● Always use genuine NISSAN adhesion balance weights.

● Balance weights are unreusable; always replace with new

ones.

● Do not install more than three sheets of balance weight.

c. If calculated balance weight value exceeds 50 g (1.76 oz), install

two balance weight sheets in line with each other as shown in the figure.

CAUTION:

Do not install one balance weight sheet on top of another.

3. Start wheel balancer again.

4. Install drive-in balance weight on inner side of road wheel in the wheel balancer indication position (angle).

CAUTION:

Do not install more than two balance weights.

5. Start wheel balancer. Make sure that inner and outer residual unbalance values are 10 g (0.35 oz) each or below.

● If either residual unbalance value exceeds 10 g (0.35 oz), repeat installation procedures.

Wheel balance (Maximum allowable unbalance):

SMA056D

Maximum allowable unbalance

Dynamic (At rim flange) Less than 10 g (0.35 oz) (one side)

Static (At rim flange) Less than 20 g (0.70 oz)

Rotation AES0000W

● Follow the maintenance schedule for tire rotation service intervals. Refer to MA-6, "PERIODIC MAINTE-

NANCE" .

● Do not include the T-type spare tire when rotating the tires.

CAUTION:

When installing wheels, tighten them diagonally by dividing the work two to three times in order to prevent the wheels from developing any distortion.

CAN COMMUNICATION

CAN COMMUNICATION PFP:23710

System Description AES000ZN

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only. Refer to LAN-21, "

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”

ADS000Y5

WARNING:

● To avoid renderi n g the SRS inoper a tive, which could increa s e th e ri s k of perso n al i njury or d e ath

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 per-

sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section.

● 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.

Precautions ADS000X1

● Before connecting or disconnecting the AWD control unit

harness connector, turn ignition switch “OFF” and disconnect battery ground cable. Because battery voltage is applied to AWD control unit even if ignition switch is turned “OFF”.

● When connecting or disconnecting pin connectors into or

from AWD control unit, take care not to damage pin terminals (bend or break). When connecting pin connectors, make sure that there are no bends or breaks on AWD control unit pin terminal.

● Before replacing AWD control unit, perform AWD control

unit input/output signal inspection and make sure whether AWD control unit functions properly or not. Refer to TF-20,

"AWD Control Unit Input/Output Signal Reference Val ues" .

PRECAUTIONS

Service Notice or Precaution ADS000X2

● Do not reuse transfer fluid, once it has been drained.

● Check the fluid level or replace the fluid only with the vehicle parked on level ground.

● During removal or installation, keep inside of transfer clear of dust or dirt.

● Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern.

Fitting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause longitudinal vibration.

● Disassembly should be done in a clean work area, it is preferable to work in dust proof area.

● Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal

parts from becoming contaminated by dirt or other foreign matter.

● All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or

reassembly.

● Check for the correct installation status prior to removal or disassembly. If matching marks are required,

be certain they do not interfere with the function of the parts when applied.

● Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them

with a new ones if necessary.

● Gaskets, seals and O-rings should be replaced any time when the transfer is disassembled.

● In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If

tightening sequence is specified, use it.

● Observe the specified torque when assembling.

● Clean and flush the parts sufficiently and blow-dry them.

● Be careful not to damage sliding surfaces and mating surfaces.

● Clean innerparts with lint-free cloth or towels. Do not use cotton work gloves and rags to prevent adhering

fibers.

System Description ADS000XA

ELECTRIC CONTROLLED COUPLING Operation Principle

SDIA2270E

1. AWD control unit supplies command current to electric controlled coupling (AWD solenoid).

2. Control clutch is engaged by electromagnet and torque is detected in control clutch.

3. The cam operates in response to control clutch torque and applies pressure to main clutch.

4. Main clutch transmits torque to front wheels according to pressing power.

● Transmission torque to front wheels is determined according

to command current.

AWD SYSTEM

AWD CONTROL UNIT

● Controls distribution of drive power between rear-wheel drive

(0:100) and AWD (50:50) conditions according to signals from sensors.

● Self-diagnosis can be done with CONSULT-II.

SDIA3036E

SNOW MODE SWITCH

Driving mode (AUTO⇔SNOW) can be selected with snow mode switch operation (OFF⇔ON).

SDIA3037E

AUTO Mode (SNOW Mode Switch: OFF)

● Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.

● Makes possible stable driving, with no wheel spin, on slippery surfaces.

● On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close

to rear-wheel drive.

● Sensor inputs determine the vehicle's turning condition, and in response tight cornering/braking are con-

trolled by distributing optimum torque to front wheels.

SNOW Mode (SNOW Mode Switch: ON)

● According to front/rear wheels distribution control to approx. “50:50” and throttle control with ECM, stable

starting is ensured when snowy roads or other slippery surfaces.

NOTE:

● When driving, if there is a large difference between front and rear wheel speed which continues for a long

time, fluid temperature of drive system parts becomes too high and AWD warning lamp flashes rapidly. (When AWD warning lamp flashes, vehicle changes to rear-wheel drive conditions.) Also, optional distribution of torque sometimes becomes rigid before lamp flashes rapidly, but it is not malfunction.

● If AWD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop

and AWD system will be restored.

● When driving, AWD warning lamp may flash slowly if there is a significant difference in diameter of the

tires. At this time, vehicle performance is not fully available and cautious driving is required. (Continues until engine is turned OFF.)

● If the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is

normal. If it again flashes slowly after driving for some time, vehicle must be inspected.

● When the difference of revolution speed between the front and rear wheel with AUTO mode the shift occa-

sionally changes to direct 4-wheel driving conditions automatically. This is not malfunction.

AWD WARNING LAMP

Turns ON when there is a malfunction in AWD system. Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1 seconds after the engine starts if system is normal.

TROUBLE DIAGNOSIS

TROUBLE DIAGNOSIS PFP:00004 Fail-Safe Function ADS000XD

● If any malfunction occurs in AWD electrical system, and control unit detects the malfunction, AWD warn-

ing lamp on combination meter turns ON to indicate system malfunction.

● When AWD warning lamp is ON, vehicle changes to rear-wheel drive or shifting driving force-AWD (Front-

wheels still have some driving torque).

How to Perform Trouble Diagnosis ADS000XE

BASIC CONCEPT

● To p er fo r m t r ou bl e d ia gn o si s , i t i s t he mo st im po rt an t t o h av e u nd e rs t an di n g a b ou t v eh ic le sy st e ms ( co n-

trol and mechanism) thoroughly.

● It is also important to clarify customer complaints before inspec-

tion. First of all, reproduce symptoms, and understand them fully. Ask customer about his/her complaints carefully. In some cases, it will be necessary to check symptoms by driving vehicle with customer.

CAUTION:

Customers are not professional. It is dangerous to make an easy guess like "maybe the customer means that...," or "maybe the customer mentions this symptom".

SEF233G

● It is essential to check symptoms right from the beginning in

order to repair malfunctions completely. For intermittent malfunctions, reproduce symptoms based on interview with customer and past examples. Do not perform inspection on ad hoc basis. Most intermittent malfunctions are caused by poor contacts. In this case, it will be effective to shake suspected harness or connector by hand. When repairing without any symptom diagnosis, you cannot judge if malfunctions have actually been eliminated.

● After completing diagnosis, always erase diagnostic memory.

Refer to TF-23, "

● For intermittent malfunctions, move harness or harness connec-
