Component Description

INFOID:0000000009177418

BCM

INFOID:0000000009177419

The BCM reads the air pressure signal received by the remote keyless entry receiver. In addition, the BCM

also uses the outside key antennas (driver side, passenger side and rear bumper) to identify the location of

the transmitters (if equipped with individual tire pressure display).

The BCM has a self-diagnosis function used to detect system malfunctions.

Transmitter

INFOID:0000000009177420

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

INFOID:0000000009177421

The remote keyless entry receiver receives the air pressure signal transmitted by the transmitter in each

wheel.

Outside Key Antennas

INFOID:0000000009177422

On vehicles equipped with individual tire pressure display, the outside key antennas (driver side, passenger

side and rear bumper) are used by the BCM to identify the location of the transmitters.

Combination Meter

INFOID:0000000009177423

The combination meter receives tire pressure status from the BCM via CAN communication. The combination

meter will display the low tire pressure warning lamp when a low tire pressure or system malfunction is

detected by the BCM. A warning message will also be displayed in the vehicle information display. Refer to the

Owner’s Manual for additional information.

System Description

INFOID:0000000009177425

When the vehicle has reached a speed of 40 km/h (25 MPH) or greater, the BCM receives a signal transmitted

from the tire pressure sensors/transmitters installed in each wheel. If the BCM detects low inflation pressure or

a system malfunction, it sends a signal to the combination meter via CAN communication to illuminate the low

tire pressure warning lamp. In addition, a warning message will be displayed in the vehicle information display.

Refer to the Owner’s Manual for additional information.

The tire pressure monitoring system (TPMS) has a tire inflation indicator function to aid in tire inflation. Refer

to 

WT-9, "Easy Fill Tire Alert Function"

.

Low Tire Pressure Warning Lamp and Display Indications

*: With individual tire pressure display.

Easy Fill Tire Alert Function

INFOID:0000000009177426

NOTE:

When beginning tire inflation, it takes a few seconds for the Easy fill tire alert to function. If there is no

response for approximately 15 seconds or more, cancel the Easy fill tire alert function and move the vehicle

approximately 1 m (3.2 ft) backward or forward to try again.

• The Easy fill tire alert function operates only when the select lever position is in P-range with the ignition

switch ON.

• This function informs the driver with a visual and audible indication that the recommended COLD tire pres-

sure has been reached.

• The hazard warning lamps blink when the recommended COLD

tire pressure has been reached. After the recommended COLD tire

pressure has been reached, the horn sounds once and the hazard

warning lamps stop blinking.

• If the tire pressure value is equal to or greater than 30 kPa (0.31

kg/cm

2

, 4 psi) more than the recommended COLD tire pressure,

the hazard warning lamps flash and horn sounds three times. 

• To return the tire to the recommended COLD tire pressure, deflate

the tire until the horn sounds once and the hazard warning lamps

stop blinking.
