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 glove box
removed. The remote keyless entry receiver receives the air pres-
sure 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. Refer to WT-17, " Self-Diagnosis (Without CONSULT-III) " . The tire pressure warning check connector
is located behind the lower portion of the instrument panel LH. Refer to PG-38, " Harness Layout " . WEIA0186E

TROUBLE DIAGNOSIS FOR
SELF-DIAGNOSTIC ITEMS
Data from Transmitter Not Being Received INFOID:0000000004307331
MALFUNCTION CODE NO. 21, 22 , 23 OR 24 (DTC C1708, C1709, C1710 OR C1711)YES >> GO TO 2.
NO >> GO TO 3. OK >> Replace BCM, then GO TO 3. Refer to
BCS-18, " Removal and Installation of BCM " .
NG >> Repair or replace remote keyless entry receiver connector. ID Registration Procedure " .
Is there a tire that cannot register ID? YES >> Replace transmitter of the
tire, then GO TO 5. Refer to WT-25, " Transmitter (Pressure Sensor) " .
NO >> GO TO 4. “ DATA MONITOR ITEM ” display tire pressure as normal without any warning lamp?
YES >> Inspection End.
NO >> GO TO 5. ID Registration Procedure " .
2. Drive at a speed of 40 km/h (25 MPH) or more fo r 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 >> GO TO the inspection applicable to DTC.
