BCM

INFOID:0000000012201835

The BCM reads the air pressure signal received by the tire pressure receiver, and controls the low tire pres-

sure warning lamp operation. It also has a judgment function to detect a system malfunction.

Tire Pressure Sensor

INFOID:0000000012201836

The tire pressure sensor integrated with a valve is installed on a wheel, and transmits a detected air pressure

signal by radio wave. 

Tire Pressure Receiver

INFOID:0000000012201837

• The tire pressure receiver is incorporated into remote keyless entry receiver.

• The tire pressure receiver receives the air pressure signal transmitted by the tire pressure sensor in each

wheel.

Information Display

INFOID:0000000012201838

The vehicle information display is shown when a low tire pressure warning lamp signal is transmitted from

BCM to combination meter via CAN communication.

Condition

System Description

INFOID:0000000012201839

• During driving, the TPMS (Tire Pressure Monitoring System) receives the signal transmitted from tire pres-

sure sensor installed in each wheel. The BCM (Body Control Module) of this system has pressure judgment

and trouble diagnosis functions. When the tire pressure monitoring system detects low inflation pressure or

another unusual symptom, the low tire pressure warning lamps in the combination meter comes on.

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

pressure is less than the specified value.

• Activates the TPMS (Tire Pressure Monitoring System) when the vehicle speed is 40 km/h (25 MPH) or

more.

SYSTEM DIAGRAM

INPUT/OUTPUT SIGNAL

Major signal transmission between each unit via communication lines is shown in the following table.

LOW TIRE PRESSURE WARNING LAMP INDICATION CONDITION

Uses CAN communication from the BCM to illuminate the low tire pressure warning lamp on the combination

meter.

DIAGNOSIS SYSTEM (BCM)

NOTE:
*: Power position shifts to “LOCK” from “OFF”, when ignition switch is in the OFF position, selector lever is in the P position (A/T models
and CVT models), and any of the following conditions are met.
• Closing door
• Opening door
• Door is locked using door request switch
• Door is locked using Intelligent Key
The power position shifts to “ACC” when the push-button ignition switch (push switch) is pushed at “LOCK”.
