LOW TIRE PRESSURE WARNING SYSTEM
Revision: June 20062007 Versa
TRANSMITTER
A sensor-transmitter integrated with a valve is installed in each
wheel, and transmits a detected air pressure signal in the form of a
radio wave. The radio signal is received by the remote keyless entry
receiver.
REMOTE KEYLESS ENTRY RECEIVER
The remote keyless entry receiver is shown with the glove box
removed. The remote keyless entry receiver receives the air pres-
sure 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 combination meter low tire pressure warn-
ing lamp is activated.

Terminals and Reference Values for BCMEES002EX
Refer to BCS-12, "Terminals and Reference Values for BCM" .
ID Registration ProcedureEES002EY
ID REGISTRATION WITH TRANSMITTER ACTIVATION TOOL
NOTE:
This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.
New replacement transmitters are provided "asleep" and must first be "woken up" using Transmitter
Activation Tool J-45295 before ID registration can be performed.
1. Connect CONSULT-II. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Select “AIR PRESSURE MONITOR” on "SELECT TEST ITEM" screen.
3. Select “WORK SUPPORT” on "SELECT DIAG MODE" screen,
and select "ID REGIST".
4. Push the transmitter activation tool against the tire near the front
left transmitter. Press the button for 5 seconds.
5. Register the IDs in order from FR LH, FR RH, RR RH and RR LH. When ID registration of each wheel has
been completed, a buzzer sounds and the hazard warning lamps flash.
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-diagnostic results dis-
play will not function properly.

Preliminary CheckEES002F4
BASIC INSPECTION
1. CHECK ALL TIRE PRESSURES
Check all tire pressures. Refer to WT-29, "
Tire" .
OK or NG
OK >> GO TO 2.
NG >> Adjust tire pressure to specified value.
2. CHECK LOW TIRE PRESSURE WARNING LAMP ACTIVATION
Check low tire pressure warning lamp activation.
Does warning lamp activate for 1 second when ignition switch is turned ON?
YES >> GO TO 3.
NO >> GO TO WT-23, "
Low Tire Pressure Warning Lamp Does Not Come On When Ignition Switch Is
Tu rne d On." .
3. CHECK BCM CONNECTOR
1. Disconnect BCM harness connector.
2. Check terminals for damage or loose connection.
3. Reconnect harness connector.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK TRANSMITTER ACTIVATION TOOL
Check transmitter activation tool battery.
OK or NG
OK >> Carry out self-diagnosis.
NG >> Replace battery in transmitter activation tool.
Self-DiagnosisEES002F1
DESCRIPTION
During driving, the low tire pressure warning 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 low tire pressure warning system detects low inflation pressure or an internal malfunction, the low
tire pressure warning lamp in the combination meter comes on. The malfunction location is indicated by the
low tire pressure warning lamp flashing and the buzzer sounding.

REMOVAL
1. Remove wheel and tire using power tool.
2. Deflate tire. Unscrew transmitter retaining nut and allow transmitter to fall into tire.
3. Gently bounce tire so that transmitter falls to bottom of tire.
Place wheel and tire assembly on tire changing machine and
break both tire beads. Ensure that the transmitter remains at the
bottom of the tire while breaking the bead.
4. Turn tire so that valve hole is at bottom, and gently bounce the
tire to ensure transmitter is near valve hole. Carefully lift tire onto
turntable and position valve hole (and transmitter) 270 degrees
from mounting/dismounting head.
5. Lubricate tire well, and remove top side of tire. Reach inside the
tire and remove the transmitter.
6. Remove the second side of the tire as normal.
INSTALLATION
1. Place first side of tire onto rim.
2. Apply suitable silicone lubricant to new transmitter seal then install seal on transmitter. Refer to MA-11,
"RECOMMENDED FLUIDS AND LUBRICANTS" .
NOTE:
Always replace the seal after every disassembly.
3. Mount transmitter on rim and tighten nut.
NOTE:
Make sure no burrs exist in the valve stem hole of the wheel.

4. Place wheel on turntable of tire machine. Ensure that transmitter
is 270 degrees from mounting/dismounting head.
NOTE:
Do not touch transmitter with mounting head.
5. Lubricate tire well, and install second side of tire as normal.
Ensure that tire does not rotate relative to rim.
6. Inflate tire and balance the wheel and tire assembly. Refer to
WT-6, "
Balancing Wheels" .
7. Install wheel and tire assembly in appropriate wheel position on
vehicle. Refer to WT-6, "
Rotation" .
NOTE:
If replacing the transmitter, then transmitter wake up operation must be performed. Refer to WT-13,
"Transmitter Wake Up Operation" .
