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 instrument
panel RH removed. The remote keyless entry 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 combination meter low tire pressure warn-
ing lamp is activated.
DISPLAY UNIT (WITH NAVI)
Displays the air pressure of each tire.
●
After the ignition switch is turned on, the pressure values will not
be displayed until the data of each wheel is received.

ID Registration Procedure
EES002U9
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.

Transmitter Wake Up Operation
EES002UA
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.
Turn ignition switch ON. Push the transmitter activation tool
against the tire near the front left transmitter. Press the button
for 5 seconds. The hazard warning lamps flash per the diagram
below.
2.
Repeat this procedure for each tire in the following order: FL, FR, RR, RL.
3.
When the BCM finishes assigning each tire ID, the BCM flashes the hazard warning lamps and sends
flashing indicator status by CAN according to the following time chart.
4.
After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.

CONSULT-II Function (BCM)
EES00245
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
Self-Diagnosis
EES002UB
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.
