System Description

TIRE PRESSURE MONITORING SYSTEM


System Description


TRANSMITTER
A sensor-transmitter integrated with a valve is installed on a wheel, and transmits a detected air pressure signal by radio wave.






RECEIVER
The receiver receives the air pressure signal transmitted by the transmitter in each wheel.






LOW TIRE PRESSURE WARNING CONTROL UNIT
The low tire pressure warning control unit (1) reads the air pressure signal received by the receiver, and controls the low tire pressure warning lamp 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 low tire pressure warning control unit using CAN communication. When a low tire pressure condition is sensed by the low tire pressure warning control unit, the combination meter low tire pressure warning lamp is activated.






Low Tire Pressure Warning Lamp Indication






DISPLAY UNIT
Display the air pressure of each tire.
- After the ignition switch is turned ON, the pressure values are not be displayed until the data of wheels stabilizes.
