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 tire balance machine again.
4. Install drive-in balance weight on inner side of road wheel in the
tire balance machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start tire balance machine. Make sure that inner and outer resid-
ual unbalance value are 7 g (0.25 oz) each or below.

If either residual unbalance value exceeds 7 g (0.25 oz), repeat installation procedures.
RotationNES000JQ

Follow the maintenance schedule for tire rotation service inter-
vals. Refer to MA-7, "
PERIODIC MAINTENANCE" .

Do not include the spare tire when rotating tires.
CAUTION:

When installing wheels, tighten them diagonally by divid-
ing 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.

System ComponentsNES000JR
System DescriptionNES000JS
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.

TIRE PRESSURE MONITORING SYSTEM
Revision: 2007 April2007 M35/M45
RECEIVER
The receiver receives the air pressure signal transmitted by the transmitter in each wheel.
LOW TIRE PRESSURE WARNING CONTROL UNIT
The low tire pressure warning control unit (1) reads the air pressure
signal received by the receiver, and controls the low tire pressure
warning lamp operations. It also has a judgementfunction to detect a
system malfunction.
LOW TIRE PRESSURE WARNING LAMP
The combination meter receives tire pressure status from the low tire
pressure warning control unit using CAN communication. When a
low tire pressure condition is sensed by the low tire pressure warn-
ing control unit, the combination meter low tire pressure warning
lamp is activated.
Low Tire Pressure Warning Lamp Indication
*: Standard air pressure is for 230 kpa (2.3 kg/cm2 , 33 psi) vehicle. 1. Tire pressure receiver front 2. Tire pressure receiver rear A. Front wheel house

DISPLAY UNIT
Display the air pressure of each tire.

After the ignition switch is turned ON, the pressure values are
not be displayed until the data of wheels stabilizes.
Can CommunicationNES000KV
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.
For details, refer to LAN-50, "
CAN System Specification Chart" .

ID Registration ProcedureNES000JY
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacement of a tire pressure transmitter, low tire pressure warn-
ing control unit, or tire rotation.
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
3. Touch “ID REGIST” on “SELECT WORK ITEM”.
4. With the activation tool (J-45295) pushed against the front-left
tire pressure transmitter position of the tire air valve, press and
hold the button for 5 seconds.
5. Register the IDs in order from FR LH, FR RH, RR RH, RR LH.
When ID registration of each wheel has been completed, turn
signal lamp blinks.
6. 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-diagnosis results
display will not function properly.
ID REGISTRATION WITHOUT ACTIVATION TOOL
This procedure must be done after replacement of a tire pressure transmitter, low tire pressure warn-
ing control unit, or tire rotation.
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
3. Touch “ID REGIST” on “SELECT WORK ITEM”.
4. Adjust the tire pressure to the values shown in the table below for ID registration, and drive the vehicle at
40 km/h (25 MPH) or more for a few minutes.
5. After completing all ID registrations, press “END” to complete the procedure.
6. Inflate all tires to proper pressure. Refer to WT-41, "
SERVICE DATA AND SPECIFICATIONS (SDS)" .

WITH TRANSMITTER ACTIVATION TOOL
1. With the activation tool (J-45295) pushed against the front-left
transmitter, press and hold the button for 5 seconds.

When ignition switch ON, as the low tire pressure warning
lamp blinks per the follow diagram, the respective transmitter
then must be wake up.
2. Register the ID of wheel that warning lamp flashes. When wake up of registered wheel has been com-
pleted, turn signal lamp flashes two times.
3. After completing wake up all transmitters, make sure low tire pressure warning lamp goes out.

Diagnosis Procedure with Warning Lamp Function (Without CONSULT-II)NES000K6
DESCRIPTION
During driving, the tire pressure monitoring system receives the signal transmitted from the transmitter
installed in each wheel when the tire pressure becomes low. The control unit (low tire pressure warning control
unit) of this system has pressure judgement and trouble diagnosis functions.
FUNCTION
When the tire pressure monitoring system detects low inflation pressure or another unusual symptom, the
warning lamps in the combination meter comes on. To start the self-diagnostic results mode, ground terminal
of the tire pressure warning check connector. The malfunction location is indicated by the warning lamp flash-
ing. Regarding location of tire pressure warning check connector, refer to PG-62, "
HARNESS" .
