BODY CONTROL MODULE (BCM)
The BCM is shown with the lower instrument panel LH 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-d iagnosis function to detect a system
malfunction.
TRANSMITTER
A sensor-transmitter integrated with a valve is installed in each
wheel, and transmits a detected air pr essure signal in the form of a
radio wave. The radio signal is received by the remote keyless entry
receiver.
