LOW TIRE PRESSURE WARNING SYSTEM
Revision: 2006 January2006 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 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 low tire
pressure warning control unit using CAN communication. When a
low tire pressure condition is sensed by the low tire pressure control
unit, the combination meter low tire pressure warning lamp and
buzzer are 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

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.
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. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)” “AIR PRESSURE MONITOR”.
If “AIR PRESSURE MONITOR” is not displayed, print the “SELECT SYSTEM” screen. Then refer to
LAN-7, "
Precautions When Using CONSULT-II" .
NOTE:
Just after starting engine, or turning ignition switch ON, it may not be displayed even if “START (NIS-
SAN BASED VHCL)” is touched. In this case, reconnect CONSULT-II and CONSULT-II CONVERTER.
5. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
6. Touch “ID REGIST” on “SELECT WORK ITEM”.
7. 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.
8. After completing all ID registrations, press “END” to complete the procedure.
9. Inflate all tires to proper pressure. Refer to WT-41, "
SERVICE DATA AND SPECIFICATIONS (SDS)" .

2. The part number described on low tire pressure warning control unit sticker is displayed.
Diagnosis Procedure with Warning Lamp Function (Without CONSULT-II)NES000K6
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (low tire pres-
sure warning control unit) of this system has pressure judgement and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning 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 and the buzzer sounds. Regarding location of tire pressure warning check connector, refer to PG-63,
"HARNESS" .

REMOVAL
1. Deflate tire. Unscrew transmitter retaining nut and allow transmitter to fall into tire.
2. Gently bounce tire so that transmitter falls to bottom of tire.
Place on tire changing machine and break both tire beads
ensuring that the transmitter remains at the bottom of the tire.
3. Turn tire so that valve hole is at bottom and bounce so that
transmitter is near valve hole. Carefully lift tire onto turntable and
position valve hole (and transmitter) 270 degree from mounting/
dismounting head.
4. Lubricate tire well and remove first side of the tire. Reach inside
the tire and remove the transmitter.
INSTALLATION
1. Put first side of tire onto rim.
2. Mount transmitter on rim and tighten nut.
CAUTION:
Speed for tightening nut should be less than 40 rpm.
