Transmitter

INFOID:0000000009267444

A sensor-transmitter integrated with a valve is installed in each wheel, and transmits a detected tire pressure

signal in the form of a radio wave.  The radio signal is received by the remote keyless entry receiver.

Low Tire Pressure Warning Lamp

INFOID:0000000009267445

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 warning lamp is acti-

vated.

TIRE PRESSURE MONITORING SYSTEM : System Description

INFOID:0000000009267447

• The BCM has pressure judgment and trouble diagnosis functions. When the BCM detects low inflation pres-

sure or another unusual symptom, the low tire pressure warning lamp in the combination meter is illumi-

nated.

• If the tire pressure is less than the specified value, the low tire pressure warning lamp illuminates.

• The TPMS (Tire Pressure Monitoring System) is activated when vehicle speed is 40 km/h (25 MPH) or more.

INPUT/OUTPUT SIGNAL

LOW TIRE PRESSURE WARNING LAMP CONTROL CONDITION

The BCM uses CAN communication to illuminate the low tire pressure warning lamp in the combination meter.

ALEIA0133GB

Component

Signal Description

BCM

Transmits the low tire pressure warning lamp signal via CAN communication to combination 
meter.

Combination meter

Transmits the vehicle speed signal via CAN communication to BCM.

Condition

DIAGNOSIS SYSTEM (BCM) (WITH INTELLIGENT KEY SYSTEM)

AIR PRESSURE MONITOR
AIR PRESSURE MONITOR : CONSULT Function (BCM - AIR PRESSURE MONI-
TOR)

INFOID:0000000009555107

NOTE:

The Signal Tech II Tool (J-50190) can be used to perform the following functions. Refer to the Signal Tech II

User Guide for additional information.

• Activate and display TPMS transmitter IDs

• Display tire pressure reported by the TPMS transmitter

• Read TPMS DTCs

• Register TPMS transmitter IDs

• Check Intelligent Key relative signal strength

• Confirm vehicle Intelligent Key antenna signal strength

SELF DIAGNOSTIC RESULT

NOTE:

Before performing self diagnostic result, be sure to register the ID, or else the actual malfunction may be differ-

ent from that displayed on CONSULT.

Refer to 

BCS-48, "DTC Index"

.
