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 5.0 g (0.2 oz) each or below.

If either residual unbalance value exceeds 5.0 g (0.2 oz), repeat installation procedures.
Wheel balance (Maximum allowable unbalance):
Tire RotationNES000GO

After rotating the tires, adjust the tire pressure.

Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
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.

Use NISSAN genuine wheel nuts for aluminum wheels.
Maximum allowable
unbalance Dynamic (At rim flange) 5.0 g (0.2 oz) (one side)
Static (At rim flange) 20 g (0.7 oz)

LOW TIRE PRESSURE WARNING SYSTEM
Revision: 2006 December 2006 FX35/FX45
LOW TIRE PRESSURE WARNING SYSTEMPFP:40300
System ComponentsNES000GP
System DescriptionNES000GQ
TRANSMITTER
A sensor-transmitter integrated with a valve is installed on a wheel,
and transmits a detected air pressure signal in the form of a radio
wave.
REMOTE KEYLESS ENTRY RECEIVER
The remote keyless entry receiver receives the air pressure signal
transmitted by the transmitter in each wheel.

BCM (BODY CONTROL MODULE)
The BCM reads the air pressure signal received by the remote key-
less entry receiver, and controls the low tire pressure warning lamp
and the buzzer operations. It also has a judgement function to detect
a system malfunction.
LOW TIRE PRESSURE WARNING LAMP
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 combination meter low tire pressure warn-
ing lamp and buzzer are activated.
Low Tire pressure Warning Lamp Indication
Note 1: Standard air pressure is for 220 kpa (2.2 kg/cm2 , 32 psi) vehicles.
DISPLAY UNIT
Displays the air pressure of each tire.

After the ignition switch is turned ON, the pressure values are
not displayed until the data of each wheel stabilizes.

CAN COMMUNICATION
Revision: 2006 December 2006 FX35/FX45
CAN COMMUNICATIONPFP:23710
System DescriptionNES000GR
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic 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-27, "
CAN COMMUNICATION" .

TROUBLE DIAGNOSES

ID Registration ProcedureNES000GV
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacement of a transmitter or BCM.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunction might be detected
during self-diagnosis depending on control unit which performs CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CONSULT-II CONVERTER to the data link con- nector, then turn the ignition switch ON.
2. Select “START (NISSAN BASED VHCL)”.
3. Select “BCM” on “SELECT SYSTEM” screen. NOTE:
If “BCM” is not indicated, go to GI-39, "
CONSULT-II Data Link Connector (DLC) Circuit" .
4. Select “AIR PRESSURE MONITOR” on “SELECT WORK ITEM” screen.
5. Select “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
6. With the activation tool (J-45295) pushed against the front-left transmitter position of the tire air valve, press and hold the but-
ton 5 seconds.
7. Register the IDs in order from FR LH, FR RH, RR RH or RR LH. When ID registration of each wheel has been completed, a buzzer sounds and turn signal lamp (LH/ RH) blinks.
8. After completing all ID registrations, press “END” to complete the procedure.
NOTE:
Be sure to register the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results dis-
play will not function properly.
