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.
TIRE PRESSURE WARNING CHECK CONNECTOR
The tire pressure warning check connector can be grounded in order to initiate self-diagnosis without a CON-
SULT-III. The tire pressure warning check connector is located behind the lower portion of the instrument
panel LH. Refer to XX-XX, *****.
DISPLAY UNIT (with BOSE™ audio system)
Displays the air pressure of each tire.
NOTE:
After the ignition switch is turned on, the pressure values will not be
displayed until the data of each wheel is received.

DIAGNOSIS SYSTEM (BCM)
CONSULT-III Function (BCM)
INFOID:0000000001277807
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
Self-Diagnosis
INFOID:0000000001277808
DESCRIPTION
During driving, the tire pressure monitoring system receives the signal transmitted from the transmitter
installed in each wheel, and turns on the low tire pressure warning lamp when the tire pressure becomes low.
The control unit (BCM) for this system has pressure judgement and self-diagnosis functions.
FUNCTION
When the tire pressure monitoring system detects low inflation pressure or an internal malfunction, the low tire
pressure warning lamp in the combination meter comes on. The malfunction is indicated by the low tire pres-
sure warning lamp flashing.

DTC CONFIRMATION PROCEDURE
1.
ID REGISTRATION AND VEHICLE DRIVING
1.
Carry out ID registration of all transmitters.
2.
Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for
10 minutes.
3.
Check all tire pressures with CONSULT-III within 5 minutes.
Does DATA MONITOR ITEM display tire pressure as normal without any warning lamp?
YES
>> Inspection End.
NO
>> Refer to
WT-13, "Data from Transmitter Not Being Received"
