Component DescriptionINFOID:0000000006225489
*: Mainly used for the tire inflation function.
Low Tire Pressure Warning Control UnitINFOID:0000000006225490
 After the low tire pressure warning control unit (1) receives the tire pressure signal from the tire pressure receiver, it controls the oper-
ation of the low tire pressure warning lamp, hazard warning lamp,
and horn.
NOTE:
The hazard warning lamp and the horn are used for the tire infla-
tion indicator function.
 Performs self-diagnosis of the Tire Pressure Monitoring System
(TPMS).
 Controls tire inflation indicator function.
TransmitterINFOID:0000000006225491
The transmitter (1) is installed at the position of the air valve on the
road wheel (2). It measures the ti re pressure and transmits the tire
pressure information by radio waves.

COMPONENT PARTS
Tire Pressure Receiver
INFOID:0000000006225492
The front tire pressure receiver (1) and rear tire pressure receiver (2)
receive the tire pressure signal by radio waves from the transmitter
at each wheel, and transmit the tire pressure signal to the low tire
pressure warning control unit.
Low Tire Pressure Warning LampINFOID:0000000006225493
Uses CAN communication from the low tire pressure warning control
unit to illuminate the low tire pressure warning lamp on the combina-
tion meter.
*: Tire pressure at each condition differs. A: Front side
B : Rear side

*: Mainly used for the tire inflation indicator function.
LOW TIRE PRESSURE WARNING LAMP CONTROL CONDITION
Uses CAN communication from the low tire pressure warning control unit to illuminate the low tire pressure
warning lamp on the combination meter.
*: Tire pressure at each condition differs.
HAZARD WARNING LAMP CONTROL CONDITION
The low tire pressure warning control unit transmits a hazard request signal to BCM. BCM blinks the hazard
warning lamp, according to the signal.
The hazard warning lamp blinks under the following conditions.
Condition of Blinking The Hazard Warning Lamp When wake-up of registered wheel has been completed. Refer to WT-28, "Work Procedure".
 When ID registration is completed. Refer to WT-29, "
Work Procedure".
 During the use of the tire inflation indicator function.
HORN CONTROL CONDITION
The low tire pressure warning control unit transmits a horn request signal to BCM. BCM controls horn sound,
according to the signal.
The horn sounds under the following condition.
Condition of Sounding Horn During the use of tire inflation indicator function.
Tire Inflation Indicator FunctionINFOID:0000000006225495
 This function operates only when the A/T shift selector position is in P-range with the ignition switch ON or
with the engine started.
NOTE:
The tire inflation indicator function is recommended to use with the engine stopped.
 This function informs the driver of the satisfaction of the recom- mended COLD tire pressure.
The hazard warning lamp blinks when reaching the recommended
COLD tire pressure during radio wave reception. After reaching the
recommended COLD tire pressure, the horn sounds once and the
hazard warning lamp stops blinking.
 When tire pressure becomes a value equal to or more than 30 kPa
(0.31 kg/cm
2, 4 psi) more than the recommended COLD tire pres-
sure, the hazard warning lamp and the horn operates three times.
After deflating the tire and reaching the recommended COLD tire
pressure, the horn sounds only once and the hazard warning lamp
stops blinking.
NOTE:
 After starting to inflate the tire, it takes a few seconds for the tire inflation indicator to function.
ABS actuator and electric unit (con-
trol unit) Transmits the vehicle speed signal (ABS) via CAN communication for low tire pressure warning
control unit.
