PRECAUTION

PRECAUTION PFP:00011

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

AKS004VC

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 a v o id r e n dering the S RS ino perative, which could increa s e the risk of pe rsonal injury or d e a th

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 AKS002L7

When you read wiring diagrams, refer to the following:

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

● Refer to PG-2, "POWER SUPPLY ROUTING" for power distribution circuit.

When you perform trouble diagnosis, refer to the following:

● Refer to GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" .

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

FRONT WIPER AND WASHER SYSTEM

FRONT WIPER AND WASHER SYSTEM PFP:28810 Component Parts and Harness Connector Location AKS002L9

PKIA6947E

System Description AKS002L8

Through the adoption of vehicle speed detect-type intermittent wiper, Front Wiper System changes wiper's intermittent time when the engine is stopped and while driving. Vehicle speed signal is send from the combination meter to BCM. BCM controls intermittent activation time and coupled activation of washer and wiper.

WIPER OPERATION Description

The wiper switch is controlled by a lever built in the combination switch. There are three wiper switch positions

● LO speed

● HI speed

● INT (intermittent)

Power is supplied at all times

● through 10A fuse [No.3, located in fuse block (J/B) No.1]

● to BCM terminal 105

With the ignition switch in the ON position, power is supplied

● through 10A fuse [No. 1, located in fuse block (J/B) No.1]

● to BCM terminal 68

● through 20A fuse [No. 34, located in fuse block (J/B) No.2]

● to front wiper motor terminal 4

Revision: 2004 October 2004 M45

WW-4

Page 9

FRONT WIPER AND WASHER SYSTEM

● to front wiper relay terminal 1

● to front washer motor terminal 1.

Ground is supplied

● to front wiper switch terminals 17 and 20

● through grounds M25 and M115.

Low (MIST) and High Speed Wiper Operation

When the wiper switch is placed in the LO or MIST position, ground is supplied

● through front wiper switch terminal 14

● to front wiper motor terminal 6.

With power and ground supplied, the front wiper motor operates at low speed. When the front wiper switch is placed in the HI position, ground is supplied

● through front wiper switch terminal 16

● to front wiper motor terminal 5.

With power and ground supplied, the front wiper motor operates at high speed.

Auto Stop Operation

When the front wiper switch is placed in the OFF position, the front wiper motor will continue to operate until the wiper arms reach the base of the windshield (Auto stop). When the front wiper switch is placed in the OFF position, ground is supplied

● from front wiper switch terminal 14

● to front wiper motor terminal 6, in order to continue front wiper motor operation at low speed.

Ground is also supplied until the wiper arms reaches the base of the windshield

● through front wiper switch terminal 13

● to front wiper relay terminal 3

● through front wiper relay terminal 4

● to front wiper motor terminal 3

● through front wiper motor terminal 1, and

● through grounds E24, E42 and E62.

When the wiper arms reach the base of the windshield, the switch in the front wiper motor moves to the “STOP” position. The ground path is interrupted and the front wiper motor stops.

Intermittent Operation

Intermittent operation is controlled by the BCM. When the front wiper switch is placed in the INT position, ground is supplied

● to BCM terminal 9

● through front wiper switch terminal 15

● to grounds M25 and M115

● through front wiper switch terminal 17.

The desired interval time is input

● to BCM terminal 48

● through front wiper switch terminal 19

● to BCM terminal 49

● through combination meter terminal 38 (vehicle speed pulse).

The desired interval time is input

● to front wiper relay terminal 2

● through BCM terminal 128.

With power and ground supplied, the front wiper relay is activated. When activated, an intermittent ground is supplied

● to front wiper motor terminal 6

● through front wiper switch terminal 14

● to front wiper switch terminal 13

Revision: 2004 October 2004 M45

Page 10

FRONT WIPER AND WASHER SYSTEM

● through front wiper relay terminal 3

● to front wiper relay terminal 5

● through grounds E24, E42 and E62.

Front wiper motor operates at desired interval with BCM terminal 9 grounded. Intermittent operation can be adjusted from: Approx. 0.9 - 45 sec.: (when vehicle is stopped), Approx. 0.4 - 30 sec.: (when vehicle is moving). Judgement on vehicle stopped or moving: Stopped, Moving: More than 5 km/h (3 MPH) Moving, Stopped: Less than 2 km/h (1 MPH)

WASHER OPERATION

With the ignition switch in the ON position, power is supplied

● through 20A fuse [No. 34, located in fuse block (J/B) No.2]

● to front washer motor terminal 1.

When the lever is pulled to the WASH position, ground is supplied

● to front washer motor terminal 2, and

● to BCM terminal 4

● from front wiper switch terminal 18

● through front wiper switch, terminal 17, and

● through grounds M25 and M115.

With power and ground supplied, the front washer motor operates. The front wiper motor operates at low speed for about 3 seconds. This feature is controlled by the BCM in the same manner as the intermittent operation.

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.

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):

ELECTRICALLY CONTROLLED POWER STEERING SYSTEM PFP:28500 Precautions AGS0003E

BEFORE DIAGNOSING THE POWER STEERING SYSTEM, ENSURE THAT Vehicle Stopped

1. Power steering components (gears, oil pump, pipes, etc.) are free from leakage, and that oil level is correct.

2. Tires are inflated to specified pressure and are of specified size, and that steering wheel is a genuine Nissan part.

3. Suspension utilizes the original design, and is free of modifications which increase vehicle weight.

4. Wheel alignment is adjusted properly.

Vehicle in Operation

1. Understand the symptom.

2. Engine is operation properly

Description AGS0003F

SYSTEM DESCRIPTION

The power steering system is a twin orifice type, which uses a vehicle-speed sensing, electronic control design. Solenoid valve sensitivity is controlled in response to vehicle speed to achieve optimum steering effort.

FAIL-SAFE FUNCTION

The fail-safe function operates to regulate solenoid valve operation in response to engine speed, thereby maintaining the required steering force.

SGIA0326E

Fail-Safe Input Conditions

Fail-safe input conditions Release conditions

No vehicle speed signal entered for at least 10 seconds while driving at an engine speed of greater than 1,500 rpm.

A vehicle speed signal of greater than 30 km/h (19 MPH) or abruptly drops below 2 km/h (1 MPH).

NOTE:

When the engine is revved up to 1,500 rpm or more for at least 10 seconds with vehicle at standstill, the failsafe function operates; however, this is not a matter of concern. The fail-safe function can be released by driving vehicle of a speed of greater than 1.4 km/h (0.9 MPH) or by turning ignition switch from “OFF” to “ON”.

● A vehicle speed signal of greater than 1.4 km/h (0.9 MPH) is

entered

● Ignition switch is turned from ″OFF″ to ″ON″.

PRECAUTIONS

PRECAUTIONS PFP:00001

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

AHS0008A

WARNING:

● To a v o id r e n dering the S RS ino perative, which could increa s e the risk of pe rsonal injury or d e a th

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 for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

AHS0008B

● Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.

● Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-

utes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

● Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the

vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installation and replace as required.

● The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to

turn steering wheel or column after removal of steering gear.

● Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad

side facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.

● Conduct self-diagnosis to check entire SRS for proper function after replacing any components.

● After air bag inflates, the front instrument panel assembly should be replaced if damaged.

● Always replace instrument panel pad following front passenger air bag deployment.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS) PFP:28556 SRS Configuration AHS0008F

PHIA0698E

The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the ON or START position. The collision modes for which supplemental restraint systems are activated are different among the SRS systems. For example, the driver air bag module and front passenger air bag module are activated in a frontal collision but not in a side collision. SRS configurations which are activated for some collision modes are as follows;

SRS configuration Frontal collision Left side collision Right side collision

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

Front Seat Belt Pre-Tensioner with Load Limiter AHS0008G

The seat belt pre-tensioner system with load limiter is installed for both the driver's seat and the front passenger's seat. It operates simultaneously with the SRS air bag system in the event of a frontal collision with an impact exceeding a specified level. When the frontal collision with an impact exceeding a specified level occurs, seat belt slack resulting from clothing or other factors is immediately taken up by the pre-tensioner. Vehicle passengers are securely restrained. When passengers in a vehicle are thrown forward in a collision and the restraining force of the seat belt exceeds a specified level, the load limiter permits the specified extension of the seat belt by the twisting of the ELR shaft, and a relaxation of the chest-area seat belt

DIAGNOSIS FUNCTION

The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II. The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system malfunction through the operation of the “AIR BAG” warning lamp. The Diagnosis mode allows the technician to locate and inspect the malfunctioning part. The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:

User mode Diagnosis mode Display type

“AIR BAG” warning lamp X X ON-OFF operation

CONSULT-II — X Monitoring

HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
