The BCM reads the air pressure signal received by the remote key-
less entry receiver, and controls the low tire pressure warning lamp
and the buzzer operations. It also has a judgment function to detect
a system malfunction.
LOW TIRE PRESSURE WARNING LAMP
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.
Low Tire pressure Warning Lamp Indication
Note 1: Standard air pressure is for 220 kpa (2.2 kg/cm2, 32 psi) vehicles.
RUN-FLAT TIRE WARNING LAMP
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 run-frat tire warning
lamp and buzzer are activated.

TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMS
TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMS
Transmitter or Control Unit (BCM)INFOID:0000000001327589
MALFUNCTION CODE NO. 21, 22, 23 OR 24
1.CHECK CONTROL UNIT
Drive for several minutes. Check all tire pr essures with CONSULT-III “DATA MONITOR ITEM”.
Are all tire pressures displayed 0 kPa?
YES >> GO TO 2.
NO >> GO TO 3.
2.CHECK REMOTE KEYLESS EN TRY RECEIVER CONNECTOR
1. Disconnect remote keyless entry receiver harness connector M98.
2. Check terminals for damage or loose connection.
3. Reconnect harness connector.
OK or NG
OK >> Replace BCM refer to BCS-13, "Removal and Installation of BCM", then GO TO 3.
NG >> Repair or replace remote keyless entry receiver harness connector.
3.ID REGISTRATION
Perform ID registration of all transmitters.
Is there any tire that ID can not be registered to?
YES >> Replace transmitter of the tire, then GO TO 5.
NO >> GO TO 4.
4.VEHICLE DRIVING
Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping. Check all tire pressures with CONSULT-III “DATA MONITOR ITEM” within 15 minutes after vehicle speed
becomes 17 km/h (11 MPH).
Does
“DATA MONITOR ITEM” display tire pressure as normal without any warning lamp?
YES >> INSPECTION END
NO >> GO TO 5.
5.ID REGISTRATION AND VEHICLE DRIVING
1. Perform ID registration of all transmitters.
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. Then check all tire pressures with CO NSULT-III “DATA MONITOR ITEM” 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.

1. Perform ID registration of all transmitters.
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.
>> GO TO 2.
2.REPLACE TRANSMITTER
1. Check low tire pressure warning condition again, replace malfunctioning transmitter.
2. Perform ID registration of all transmitters.
