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 instrument
panel RH 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 warn-
ing lamp is activated. A CHECK TIRE PRESSURE warning mes-
sage will also be displayed in the odometer. Refer to the Owner’s
Manual for additional information.
TIRE PRESSURE WARNING CHECK CONNECTOR
The tire pressure warning check connector can be grounded in order
to initiate self-diagnosis without a CONSULT. Refer to
. The tire pressure warning check
connector (1) is located behind the lower portion of the instrument
panel LH.
