Combination meter | Transmits the vehicle speed signal via CAN communication to BCM. |
Receives the low tire pressure warning lamp signal via CAN communication from BCM. |
BCM
The BCM reads the tire 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 self-diagnosis function to detect a system malfunction.
Remote Keyless Entry Receiver
The remote keyless entry receiver receives the tire pressure signal transmitted by the transmitter in each wheel.
Transmitter
A sensor-transmitter integrated with a valve is installed in each wheel, and transmits a detected tire pressure signal in the form of a radio wave. The radio signal is received by the remote keyless entry receiver.
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.
