System Description
BODY CONTROL MODULE (BCM)
The BCM is shown with the instrument panel LH 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 next to the steering column assembly (2) 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. Refer to WT-53, "Self-Diagnosis (Without CONSULT-III)". The tire pressure warning check connector (1) is located behind the lower portion of the instrument panel LH.

Refrigerant Cycle
Refrigerant flow
The refrigerant flows in the standard pattern, that is, through the
compressor, the condenser with liquid tank,
through the evaporator, and back to the compressor. The refrigerant evaporation
through the evaporator coil is
controlled by an externally equal ...
