System Description INFOID:0000000003895056

BODY CONTROL MODULE (BCM)

The BCM (1) is shown with the combination meter removed. The

BCM reads the air pressure signal received by the tire pressure

receiver, and controls the low tire pressure warning lamp as shown

below. It also has a self-diagnosis function to detect a system mal-

function.

TRANSMITTER

A sensor-transmitter integrated with a valve is installed in each

wheel. It transmits a detected air pressure signal in the form of a

radio wave when the vehicle is moving. The radio signal is received

by the tire pressure receiver.

The tire pressure receiver (1) is located on the RH side of the steer-

ing column, and is shown with the lower instrument panel LH

removed. The tire pressure receiver receives the air pressure signal

transmitted by the transmitter in each wheel.

COMBINATION METER

The combination meter receives tire pressure status from the BCM

using CAN communication. When a low tire pressure condition is

sensed by the BCM, the low tire pressure warning lamp is activated.

TIRE PRESSURE WARNING CHECK CONNECTOR

The tire pressure warning check connector can be grounded in order

to initiate self-diagnosis without a CONSULT-III. Refer to WT-12,

"Self-Diagnosis (Without CONSULT-III)". The tire pressure warning

check connector (1) is located behind the lower portion of the instru-

ment panel LH, above the hood release handle.

CONSULT-III DIAGNOSTIC MODES

CONSULT-III can display each diagnostic item using the diagnostic test modes as shown.

DESCRIPTION

During driving, the tire pressure monitoring system receives the signal transmitted from the transmitter

installed in each wheel, and turns on the low tire pressure warning lamp when the tire pressure becomes low.

The control unit (BCM) for this system has pressure judgement and self-diagnosis functions.

FUNCTION

When the tire pressure monitoring system detects low inflation pressure or an internal malfunction, the low tire

pressure warning lamp in the combination meter comes on. The malfunction is indicated by the low tire pres-

sure warning lamp flashing.

PRECAUTIONS

Supplemental Restraint System (SRS) AIR BAG and SEAT BELT PRE-TEN-

SIONER INFOID:0000000003895077

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 SR and SB section of this Service Man-

ual.

WARNING:

• To avoid rendering the SRS inoperative, 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 unintentional activation of the system. For removal of Spiral Cable and Air Bag

Module, see the SR 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 har-

ness connectors.

Precautions Necessary for Steering Wheel Rotation after Battery Disconnect

INFOID:0000000004394045

NOTE:

• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-

tion, then disconnect both battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both

battery cables.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.

This vehicle is equipped with a push-button ignition switch and a steering lock unit.

If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.

If turning the steering wheel is required with the battery disconnected or discharged, 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. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.

(At this time, the steering lock will be released.)

3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-

nected and the steering wheel can be turned.

4. Perform the necessary repair operation.

5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn

the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering

wheel will lock when the push-button ignition switch is turned to LOCK position.)

6. Perform self-diagnosis check of all control units using CONSULT-III.

Precaution for work INFOID:0000000003895078

• After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check their

operation.

• Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.

ROAD WHEEL TIRE ASSEMBLY

Adjustment INFOID:0000000003895083

WHEEL BALANCE

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

CAUTION:

• Be careful not to scratch the wheel during removal procedures.

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.

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

• 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.

4. When inner and outer unbalance values are shown on the wheel

balancer indicator, multiply outer unbalance 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 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 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 posi-

tion (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.

5. Start wheel balancer again.

6. 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.

7. Start wheel balancer. Make sure that inner and outer residual

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

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

TIRE ROTATION

• Use power tool to remove wheel and tire assembly.

• Follow the maintenance schedule for tire rotation service intervals.

Refer to MA-7, "FOR NORTH AMERICA : Explanation of General

Maintenance".

CAUTION:

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

• When installing wheels, tighten them diagonally by dividing

the work two to three times in order to prevent the wheels

from developing any distortion.

• Be careful not to tighten wheel nut at torque exceeding the

criteria for preventing strain of disc rotor.
