PRECAUTION PFP:00011

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

EKS00DEF

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 ren dering the SRS inoperativ e, w h ich cou ld increa se the risk o f perso nal 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 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.

System Description EKS00DEI

● Both front wiper relays are located in the IPDM E/R (intelligent power distribution module engine room).

● The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input ter-

minals. Terminal combination status is read by the BCM (body control module) when the wiper switch is turned ON.

● BCM controls front wiper LO, HI, and INT (intermittent) operation.

● IPDM E/R operates the wiper motor according to CAN communication signals from the BCM.

Power is supplied at all times

● to ignition relay, located in the IPDM E/R, and

● through 50A fusible link (letter g , located in the fuse and fusible link box)

● to BCM terminal 70, and

● through 30A fuse (No. 39, located in the IPDM E/R)

● to front wiper relay (located in the IPDM E/R).

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

● to ignition relay, located in the IPDM E/R, and

● through 10A fuse [No. 15, located in the fuse block (J/B)]

Revision: September 2005 2006 Xterra

WW-4

Page 12

FRONT WIPER AND WASHER SYSTEM

● to combination switch terminal 2, and

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

● to BCM terminal 38.

Ground is supplied

● to BCM terminal 67 and

● to combination switch terminal 9

● through grounds M57, M61 and M79, and

● to IPDM E/R terminals 38 and 59 and

● to front wiper motor terminal 2

● through grounds E9, E15 and E24.

LOW SPEED WIPER OPERATION

When the ignition switch is in the ON or START position, and the front wiper switch is turned to the low position, the BCM detects a low speed wiper ON request through the combination switch (wiper switch) reading function. The BCM then sends a front wiper (low) request signal over CAN communication lines

● from BCM terminals 39 and 40

● to IPDM E/R terminals 39 and 40.

When IPDM E/R receives front wiper (low) request signal, it supplies ground to energize the front wiper relay. With the front wiper relay energized, power is supplied

● through front wiper relay

● to front wiper high relay

● through IPDM E/R terminal 32

● to front wiper motor terminal 1.

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

HI SPEED WIPER OPERATION

When the ignition switch is in the ON or START position, and the front wiper switch is turned to the high position, the BCM detects a high speed wiper ON request through the combination switch (wiper switch) reading function. The BCM then sends a front wiper (high) request signal over CAN communication lines

● from BCM terminals 39 and 40

● to IPDM E/R terminals 39 and 40.

When the IPDM E/R receives a front wiper (high) request signal, it supplies ground to energize the front wiper and the front wiper high relays. With the front wiper and the front wiper high relays energized, power is supplied

● through front wiper relay

● to front wiper high relay

● through IPDM E/R terminal 35

● to front wiper motor terminal 4.

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

INTERMITTENT OPERATION

Wiper intermittent operation delay interval is determined from the combination of the intermittent wiper dial position inputs and vehicle speed. 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 an intermittent position, the BCM detects a front wiper (intermittent) ON request through the combination switch (wiper switch) reading function. The BCM then sends a front wiper (intermittent) request signal over CAN communication lines

● from BCM terminals 39 and 40

● to IPDM E/R terminals 39 and 40.

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

Revision: September 2005 2006 Xterra

WW-5

Page 13

FRONT WIPER AND WASHER SYSTEM

● BCM detects ON/OFF status of intermittent wiper dial position.

● BCM calculates operation interval from wiper dial position and vehicle speed signal received through CAN

communications.

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

When the IPDM E/R receives a front wiper request signal (INT), it supplies ground to energize the front wiper relay. It then sends an auto stop signal to the BCM, and conducts intermittent front wiper motor operation.

AUTO STOP OPERATION

When the wiper arms are not located at the base of the windshield, and the wiper switch is turned OFF, the wiper motor will continue to operate until the wiper arms reach the windshield base. When the wiper arms reach the base of windshield, front wiper motor terminals 5 and 2 are connected. Ground is supplied

● to IPDM E/R terminal 43

● through front wiper motor terminal 5

● through front wiper motor terminal 2

● through grounds E9, E15 and E24.

The IPDM E/R sends an auto stop operation signal to the BCM through CAN communication lines. When the BCM receives an auto stop operation signal, the BCM sends wiper stop signal to the IPDM E/R over CAN communication lines. The IPDM E/R then de-energizes the front wiper relay. The wiper motor will then stop the wiper arms at the STOP position.

FRONT WASHER OPERATION

When the ignition switch is in the ON or START position, and the front and rear washer switches are OFF, the front and rear washer motor is supplied power

● through 10A fuse [No. 15, located in the fuse block (J/B)]

● through combination switch (wiper switch) terminal 2

● through combination switch (wiper switch) terminal 4

● to front and rear washer motor terminal 1.

When the front wiper switch is in the front washer position, the BCM detects a front washer signal request through the combination switch (wiper switch) reading function. Combination switch ground is supplied

● to front and rear washer motor terminal 2

● through combination switch (wiper switch) terminal 3

● through combination switch (wiper switch) terminal 9

● through grounds M57, M61 and M79.

With ground supplied, the front and rear washer motor is operated in the front direction. When the BCM detects that front washer motor has operated for 0.4 seconds or longer, the BCM uses CAN communication and sends a wiper request signal to the IPDM E/R for low speed operation of wipers. When the BCM detects that the washer switch is OFF, low speed operation cycles approximately 3 times and then stops.

MIST OPERATION

When the wiper switch is temporarily placed in 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 the switch is held in the mist position, low speed operation continues.

FAIL-SAFE FUNCTION

The BCM includes fail-safe function to prevent malfunction of electrical components controlled by CAN communications if a malfunction in CAN communications occurs. The BCM uses CAN communications to stop output of electrical components it controls. Until the ignition switch is turned OFF, the front wiper system remains in same status as just before fail-safe control was initiated. (If wiper was in low speed operation just before fail-safe, it continues low speed operation until ignition switch is turned OFF.) When fail-safe status is initiated, the BCM remains in standby until normal signals are received. When normal signals are received, fail-safe status is canceled.

System Description EKS00DF2

● The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input ter-

minals. Terminal combination status is read by the BCM (body control module) when switch is turned ON.

● The BCM controls rear wiper ON and INT (intermittent) operation.

Power is supplied at all times

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

● to BCM terminal 70.

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

● through 10A fuse [No. 15, located in the fuse block (J/B)]

● to combination switch terminal 2, and

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

● to BCM terminal 38.

Ground is supplied

● to BCM terminal 67 and

● to combination switch terminal 9

● through grounds M57, M61 and M79.

REAR WIPER OPERATION

When the ignition switch is in the ON or START position, and the rear wiper switch is in the ON position, the BCM detects a rear wiper ON request through the combination switch (wiper switch) reading function. The BCM will control the rear wiper motor as follows. Power is supplied

● through BCM terminal 55

● to rear wiper motor terminal 4.

Ground is supplied

● to rear wiper motor terminal 1

● through grounds D406 and D652.

With power and ground supplied, the rear wiper motor operates.

INTERMITTENT OPERATION

The rear wiper motor operates the wiper arm at low speed approximately every 7 seconds.

Revision: September 2005 2006 Xterra

WW-32

Page 40

REAR WIPER AND WASHER SYSTEM

When the wiper switch is in the rear wiper INT position, the BCM detects a rear wiper INT request through the combination switch (wiper switch) reading function. When BCM operates rear wiper motor, power is supplied

● through BCM terminal 55

● to rear wiper motor terminal 4.

Ground is supplied

● to rear wiper motor terminal 1

● through grounds D406 and D652.

With power and ground supplied, the rear wiper operates in intermittent mode.

AUTO STOP OPERATION

When the rear wiper arm is not located at the base of the rear window, and the rear wiper switch is turned OFF, the rear wiper motor will continue to operate until the rear wiper arm is at the base of the rear window. When the rear wiper arm reaches the base, rear wiper motor terminals 2 and 1 are connected. Ground is supplied

● to BCM terminal 44

● through rear wiper motor terminal 2

● through rear wiper motor terminal 1

● through grounds D406 and D652.

REAR WASHER OPERATION

When the ignition switch is in the ON or START position, and the front and rear washer switches are OFF, the front and rear washer motor is supplied power

● through 10A fuse [No. 15, located in the fuse block (J/B)]

● through combination switch (wiper switch) terminal 2

● through combination switch (wiper switch) terminal 3

● to front and rear washer motor terminal 2.

When the rear wiper switch is in rear washer position, the BCM detects a rear washer signal by BCM wiper switch reading function. Combination switch ground is supplied

● to front and rear washer motor terminal 1

● through combination switch (wiper switch) terminal 4

● through combination switch (wiper switch) terminal 9

● through grounds M57, M61 and M79.

With ground supplied, the front and rear washer motor is operated in the rear direction. When the BCM detects that the rear washer motor has operated for 0.4 seconds or longer, BCM operates the rear wiper motor. When the BCM detects that the rear washer switch is in OFF, the rear wiper motor cycles approximately 3 times and then stops. If the rear washer is operated with the rear wiper switch in the INT position, normal rear wiper operation will take over. Once the rear washer switch is released the rear wiper will return to INT operation.

WHEEL AND TIRE ASSEMBLY

WHEEL AND TIRE ASSEMBLY PFP:40300 Balancing Wheels EES001RF

WHEEL BALANCE REMOVAL

1. Remove wheel and tire using power tool.

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

CAUTION:

● Be careful not to scratch the wheel during removal.

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

wheel.

WHEEL BALANCE INSTALLATION AND 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 wheels.

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

2. When inner and outer imbalance values are shown on the wheel balancer indicator, multiply outer imbalance value by 1.6 to determine balance weight that should be used. Select the outer balance weight with a value closest to the calculated value 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 wheel.

Indicated imbalance 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 g = 35 g (1.23 oz)

37.5 g = 40 g (1.41 oz)

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

area on the inner wall of the wheel as shown 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 not reusable; always replace with

new ones.

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

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

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

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 imbalance values are 5g (0.18 oz) each or below.

● If either residual imbalance value exceeds 5 g (0.18 oz), repeat installation procedures.

Wheel balance (Maximum allowable imbalance):

Maximum allowable imbalance

Dynamic (At rim flange) 5 g (0.18 oz) (one side)

1. Remove wheels and tires.

2. Rotate wheels and tires on each side from front to back as shown. Do not include the spare wheel and tire when rotating the wheels and tires.

Wheel nut : 133 N·m (14 kg-m, 98 ft-lb)

CAUTION:

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

3. Adjust the tire pressure to specification. Refer to WT-34, "

PRECAUTIONS

PRECAUTIONS PFP:00001

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

EHS001DP

WARNING:

● To avoid ren dering the SRS inoperativ e, w h ich cou ld increa se the risk o f perso nal 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 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

EHS001DQ

● 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.

● The air bag diagnosis sensor unit must always be installed with the arrow mark “⇐” pointing toward the

front of the vehicle for proper operation. Also check the air bag 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.

The air bag deploys if the air bag diagnosis sensor unit is activated 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, front passenger air bag module and front seat belt pre-tensioners are activated in a frontal collision but not in a side collision. SRS configurations for some collision modes are as follows:

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

Front Seat Belt Pre-tensioner with Load Limiter EHS001G4

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 web tension while maintaining force.

WHIA0225E

Front Side Air Bag EHS001G5

Front side air bag modules are built into the front seatback assemblies. Vehicles with side air bags are equipped with labels as shown.

WHIA0008E

Side Curtain Air Bag EHS001G6

Side curtain air bag modules are located above the vehicle headlining. Vehicles with side curtain air bags are equipped with labels as shown.

WHIA0041E

Occupant Classification System (OCS) EHS001SE

The occupant classification system (OCS) identifies different size occupants, out of position occupants, and detects if child seat is present in the front passenger seat. The OCS receives inputs from the occupant classification sensor (located inside the passenger seat cushion assembly) and belt tension sensor (part of the passenger front seat belt assembly and located at the belt anchor location). Depending on classification of the passenger, the OCS sends a signal to the air bag diagnosis sensor unit. The air bag diagnosis sensor unit uses this signal and the seat belt buckle switch RH signal to determine deployment or non deployment of the passenger front air bag in the event of a collision. Depending on the signals received, the air bag diagnosis sensor unit can disable the passenger front air bag completely.

NOTE:

In case of customer concern, CONSULT-II can be used to confirm the passenger air bag status (readiness).
