Tire Monitoring System: Description and Operation

System Description





System Components

TRANSMITTER





A sensor-transmitter integrated with a valve is installed on a wheel, and transmits a detected air pressure signal in the form of a radio wave.

REMOTE KEYLESS ENTRY RECEIVER





Receives the air pressure signal transmitted by the transmitter in each wheel.

BCM (BODY CONTROL MODULE)





Reads the air pressure signal received by the remote keyless entry receiver, and controls the low tire pressure warning lamp and the buzzer operations as shown below. It also has a judgement function to detect a system malfunction.

WARNING LAMP AND BUZZER








Indicates low tire pressure or system malfunction.

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 warning lamp and buzzer are 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.
