Component Description

BCM

INFOID:0000000009758128

The BCM reads the tire pressure signal received by the remote keyless entry receiver, and controls the low tire

pressure warning lamp and the buzzer operations. It also has a self-diagnosis function to detect a system mal-

function.

Remote Keyless Entry Receiver

INFOID:0000000009758129

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

wheel.

Transmitter

INFOID:0000000009758130

A sensor-transmitter integrated with a valve is installed in each wheel, and transmits a detected tire pressure

signal in the form of a radio wave. The radio signal is received by the remote keyless entry receiver.

Low Tire Pressure Warning Lamp

INFOID:0000000009758131

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 warning lamp is acti-

vated.

Combination Meter

INFOID:0000000010287675

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.

TIRE PRESSURE MONITORING SYSTEM : System Description

INFOID:0000000009758133

• The BCM has pressure judgment and trouble diagnosis functions. When the BCM detects low inflation pres-

sure or another unusual symptom, the low tire pressure warning lamp in the combination meter is illumi-

nated.

• If the tire pressure is less than the specified value, the low tire pressure warning lamp illuminates.

• The TPMS (Tire Pressure Monitoring System) is activated when vehicle speed is 40 km/h (25 MPH) or more.

INPUT/OUTPUT SIGNAL

LOW TIRE PRESSURE WARNING LAMP CONTROL CONDITION

The BCM uses CAN communication to illuminate the low tire pressure warning lamp in the combination meter.

TIRE PRESSURE MONITORING SYSTEM : Easy Fill Tire Alert Function

INFOID:0000000009758134

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.
