Tire Pressure Monitoring System

System Component





System Description

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





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

BCM (BODY CONTROL MODULE)





The BCM reads the air 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 judgment function to detect a system malfunction.

LOW TIRE PRESSURE WARNING LAMP





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 activated.

Low Tire pressure Warning Lamp Indication





RUN-FLAT TIRE WARNING LAMP





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 run-flat tire warning lamp and buzzer are activated.

DISPLAY UNIT





Displays the air pressure of each tire.
^ After the ignition switch is turned ON, the pressure values are not displayed until the data of each wheel stabilizes.
