PRECAUTION

PRECAUTION PFP:00011

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

AKS008YI

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 void renderi ng th e SR S inope r a tive, which could increas e th e risk of p e rsonal injury or d eath

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.

FRONT WIPER AND WASHER SYSTEM PFP:28810 Components Parts and Harness Connector Location AKS004T5

SKIA2211E

System Description AKS004T6

● 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 (body control module) controls front wiper LO, HI, and INT (intermittent) operation.

● IPDM E/R (intelligent power distribution module engine room) operates wiper motor according to CAN

communication signals from BCM.

LOW SPEED WIPER OPERATION

Power is supplied at all times

● from BCM (input 1) terminal 48

● to combination switch terminal 17

● to 20A fuse (No. 74, located in IPDM E/R) and

● through IPDM E/R terminal 42

● to wiper motor terminal 4.

When the ignition switch is in the ON or START position, and front wiper switch is turned to LO position, front wiper LO contact in combination switch comes ON, and Power is supplied

● through combination switch terminal 10

● to BCM (output 3) terminal 41.

When BCM determines that wiper switch is in LO position, it uses CAN communications and Front wiper request signal (LO) is sent

● from BCM terminals 70 and 71

● to IPDM E/R terminals 48 and 49.

Revision; 2004 April 2003 G35 Sedan

WW-4

Page 12

FRONT WIPER AND WASHER SYSTEM

When IPDM E/R receives front wiper request signal (LO), it turns ON front wiper LO relay (in IPDM E/R). Ground is supplied

● from wiper motor terminal 3,

● through IPDM E/R terminal 31 and front wiper HI and LO relays

● to IPDM E/R terminal 14

● through grounds E17 and E43.

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

HI SPEED WIPER OPERATION

Power is supplied at all times

● from BCM (input 2) terminal 49

● to combination switch terminal 2

● to 20A fuse (No. 74, located in IPDM E/R) and

● through IPDM E/R terminal 42

● to wiper motor terminal 4.

When the ignition switch is the ON or START position, and the front wiper switch is turned to HI position, front wiper HI contact in combination switch comes ON, and Power is supplied

● through combination switch terminal 6

● to BCM (output 1) terminal 47.

When BCM determines that wiper switch is in HI position, it uses CAN communications and Front wiper request signal (HI) is sent to IPDM E/R

● from BCM terminals 70 and 71

● to IPDM E/R terminals 48 and 49.

When the IPDM E/R receives front wiper request signal (HI), it turns ON front wiper LO relay and front wiper HI relay. (in IPDM E/R), Ground is supplied

● to front wiper motor terminal 2

● through IPDM E/R terminal 30 and front wiper HI relay and front wiper LO relay

● to IPDM E/R terminal 14

● through grounds E17 and E43.

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

INTERMITTENT OPERATION

Power is supplied at all times

● from BCM (input 2) terminal 49

● to combination switch terminal 2.

When the ignition switch is in ON or START position, and the front wiper switch is turned to INT position, the front wiper INT contact in the combination switch comes ON, and power is supplied

● from combination switch terminal 10

● to BCM (output 3) terminal 41.

When BCM determines that combination switch status is front wiper INT ON, it performs the following operations.

● When BCM detects ON/OFF status of intermittent operation dial positions 1, 2, and 3 (in same way as

wiper INT), it determines wiper dial position status.

● BCM calculates operation interval from wiper dial position and vehicle speed signal received from combi-

nation meter through CAN communications.

● BCM sends front wiper request signal (INT) to IPDM E/R at calculated operation interval.

When IPDM E/R receives front wiper request signal (INT), it turns ON internal front wiper relay. It then sends auto-stop signal to BCM, and conducts intermittent front wiper motor operation.

FRONT WIPER AND WASHER SYSTEM

AUTO STOP OPERATION

With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base. When wiper arms are not located at base of windshield with wiper switch OFF, ground is provided

● from IPDM E/R terminal 31

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

Ground is also supplied

● through IPDM E/R terminal 38

● to front wiper motor terminal 1

● through front wiper motor terminal 5, and

● through grounds E17 and E43.

When wiper arms reach base of windshield, front wiper motor terminals 1 and 4 are connected instead of terminals 1 and 5. Then the IPDM E/R sends auto stop operation signal to BCM with CAN communication line. When 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 ignition switch is in ON or START position, power is supplied

● from BCM (input 1) terminal 48

● to combination switch terminal 1

● through 10A fuse (No. 87 located in IPDM E/R)

● through IPDM E/R terminal 18

● to washer motor terminal 2.

When front wiper switch is turned to washer position, Ground is supplied

● to washer motor terminal 1

● through combination switch terminal 11

● through combination switch terminal 12

● from grounds M30 and M66.

With ground supplied, the front washer motor is operated, and at the same time, Power is supplied

● through combination switch terminal 7

● to BCM (output 2) terminal 40.

When BCM detects that front washer motor has operated for 0.4 seconds or longer, BCM uses CAN communication and sends wiper request signal to IPDM E/R for low speed operation of wipers. When BCM detects that washer switch is OFF, low speed operation cycles approximately 3 times and then 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-4, "

LOW SPEED WIPER OPERATION" .

BCM WIPER SWITCH READING FUNCTION

BCM reads combination switch (wiper switch) status, and controls front wipers based on the results. BCM is a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads 20 types of switch data and 5 types of diagnosis data.

SKIA3873E

OPERATION DESCRIPTION

BCM continuously outputs power voltage from input terminals (INPUT 1 - 5). At this time, output terminals (OUTPUT 1 - 5) operate transistors in sequence and carry current. If any switch (or switches) becomes ON at this time, the input terminal corresponding to that switch detects current flowing, and BCM determines that the switch is ON.

TABL E OF BC M - CO MBI NATI ON SWI TCH OP ERATION S

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

SKIA2101E

Revision; 2004 April 2003 G35 Sedan

Page 15

FRONT WIPER AND WASHER SYSTEM

SAMPLE OPERATION: (WIPER SWITCH TURNED TO LO POSITION)

● When wiper switch is turned to LO position, front wiper LO contact inside combination switch becomes

ON. At this time, OUTPUT 3 transistor operates and BCM detects flow of current at INPUT 1.

● When OUTPUT 3 transistor is ON and BCM detects current flowing at INPUT 1, BCM determines that

wiper switch is at LO. BCM uses CAN communication and sends front wiper signals to IPDM E/R.

● When OUTPUT 3 transistor operates again and BCM again detects current flowing at INPUT 1, it confirms

that front wiper LO operation is continuing.

SKIA4468E

NOTE:

Each OUTPUT terminal transistor operates at 10 ms intervals. Therefore, a delay occurs between the switch becoming ON and operation of the electric load. However, this delay is so small it is undetectable.

OPERATING MODES

The following operation modes exist for combination switch reading function.

Normal Status

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

Sleep Status

When BCM is in sleep status, output from OUTPUT 1 and 2 transistors stops, with BCM entering a power-saving mode. OUTPUT (3 - 5) turns ON-OFF every 60 ms, and only input from lighting switch system is accepted.

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.

Example: For wiper dial position 1... Using combination switch reading function, BCM detects ON/OFF status of intermittent operation dial positions 1, 2, and 3. When combination switch status is as listed below, BCM determines that it is wiper dial position 1.

● Intermittent operation dial position 1: ON (input 3 and output 1 are conducting.)

● Intermittent operation dial position 2: ON (input 5 and output 1 are conducting.)

● Intermittent operation dial position 3: ON (input 4 and output 2 are conducting.)

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.

CAN Communication System Description AKS005L7

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.

ROAD WHEEL TIRE ASSEMBLY

ROAD WHEEL TIRE ASSEMBLY PFP:40300 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.

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):

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:

PRECAUTIONS

PRECAUTIONS PFP:00001

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

AHS00019

WARNING:

● To a void renderi ng th e SR S inope r a tive, which could increas e th e risk of p e rsonal injury or d eath

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

AHS00009

● 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 turn steer-

ing wheel and 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 AHS0000C

WHIA0042E

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

Driver air bag module × ——

Front passenger air bag module × ——

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

Front Seat Belt Pre-tensioner with Load Limiter AHS0000D

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

TROUBLE DIAGNOSIS

TROUBLE DIAGNOSIS PFP:00004 Trouble Diagnosis Introduction AHS000NE

CAUTION:

● Do not use electrical test equipment on any circuit related to the SRS unless instructed in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

● Do not repair, splice or modify the SRS wiring harness. If the harness is damaged, replace it with a

new one.

● Keep ground portion clean.

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 DIAGNOSIS FOR QUICK AND ACCURATE REPAIR

A good understanding of the malfunction conditions can make troubleshooting faster and more accurate. In general, each customer feels differently about a malfunction. It is important to fully understand the symptoms or conditions for a customer complaint.

Information from Customer

WHAT..... Vehicle model

WHEN..... Date, Frequencies

WHERE..... Road conditions

HOW..... Operating conditions, Symptoms

Preliminary Check

Make sure the following parts are in good order.

● Battery (Refer to SC-4, "How to Handle Battery" .)

● Fuse (Refer to SRS-12, "Wiring Diagram — SRS —" .)

DIAGNOSIS MODE FOR CONSULT-II

● “SELF-DIAG [CURRENT]”

A current self-diagnosis results (also indicated by the number of warning lamp flashes in the Diagnosis mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring repairs.

● “SELF-DIAG [PAST]”

Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored results are not erased until memory erasing is executed.

● “TROUBLE DIAG RECORD”

With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed on the CONSULT-II screen.

● “ECU DISCRIMINATED NO.”

The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification number. This number will be displayed on the CONSULT-II screen, as shown. When replacing the diagnosis sensor unit, refer to the part number for the compatibility. After installation, replacement with a correct unit can be checked by confirming this classification number on the CONSULT-II screen. After repair, make sure the discriminated number of diagnosis sensor unit installed to vehicle are same. Refer to SRS-49,

"ECU DISCRIMINATED NO." .
