System Description


BODY CONTROL MODULE (BCM)





The BCM (1) is shown with the combination meter removed. The
BCM reads the air pressure signal received by the tire pressure 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. It transmits a detected air pressure signal in the form of a radio wave when the vehicle is moving. The radio signal is received by the tire pressure receiver.

TIRE PRESSURE RECEIVER





The tire pressure receiver (1) is located on the RH side of the steering column, and is shown with the lower instrument panel LH removed. The tire pressure 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 low tire pressure warning lamp is activated.

TIRE PRESSURE WARNING CHECK CONNECTOR





The tire pressure warning check connector can be grounded in order to initiate self-diagnosis without a CONSULT-III. Self-Diagnosis (Without CONSULT-III). The tire pressure warning check connector (1) is located behind the lower portion of the instrument panel LH, above the hood release handle.
