Tire Pressure Monitoring System

System Component





System Description

BODY CONTROL MODULE (BCM)








The BCM is shown with the glove box removed. The BCM reads the air pressure signal received by the remote keyless entry receiver, and controls the low tire pressure warning lamp as shown below. It also has a self-diagnosis function to detect a system malfunction.

TRANSMITTER





A sensor-transmitter integrated with a valve is installed in each wheel, and transmits a detected air pressure signal in the form of a radio wave. The radio signal is received by the remote keyless entry receiver.

REMOTE KEYLESS ENTRY RECEIVER





The remote keyless entry receiver is shown with the glove box removed. The remote keyless entry receiver receives the air pressure signal transmitted by the transmitter in each wheel.

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 is activated.
