INSPECTION AND ADJUSTMENT

1. Turn ignition switch ON. Push the transmitter activation tool

against the tire near the front left transmitter. Press the button for

5 seconds.  The hazard warning lamps flash per the following

diagram.

2. Repeat this procedure for each tire in the following order: FL, FR, RR, RL.
3. When the BCM finishes assigning each tire ID, the BCM flashes the hazard warning lamps and sends

flashing indicator status by CAN according to the following time chart.

4. After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.

ID Registration Procedure

INFOID:0000000006246359

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

ID REGISTRATION WITH TRANSMITTER ACTIVATION TOOL

NOTE:

This procedure must be done after replacement of a TPMS transmitter or BCM. New replacement transmitters

are provided "asleep" and must first be "woken up" using Transmitter Activation Tool J-45295 or Signal Tech II

Tool J-50190 before ID registration can be performed. Use the following procedure when using the Transmitter

Activation Tool J-45295.
1. Connect CONSULT-III.
2. Select ID REGIST under BCM.

3. Push the transmitter activation tool against the tire near the front

left transmitter. Press the button for 5 seconds.

4. Register the IDs in order from FR LH, FR RH, RR RH and RR LH. When ID registration of each wheel has

been completed, the hazard warning lamps flash.

5. After completing all ID registrations, press END to complete the procedure.

NOTE:

Be sure to register all of the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results

display will not function properly.

ID REGISTRATION WITHOUT TRANSMITTER ACTIVATION TOOL

NOTE:

This procedure must be done after replacement of a TPMS transmitter or BCM. New replacement transmitters

are provided "asleep" and must first be "woken up" using Transmitter Activation Tool J-45295 or Signal Tech II

Tool J-50190 before ID registration can be performed.
1. Connect CONSULT-III.
2. Select ID REGIST under BCM.
3. Adjust the tire pressures to the values shown in the table and drive the vehicle at 40 km/h (25 MPH) or

more for a few minutes.

4. After completing all ID registrations, press END to complete the procedure.

5. Inflate all tires to proper pressure. Refer to 

WT-54, "Tire"

System Diagram

INFOID:0000000006246360

System Description

INFOID:0000000006246361

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.

BODY CONTROL MODULE (BCM)

The BCM (1) is shown with the lower instrument panel LH removed.

The BCM reads the air pressure signal received by the remote key-

less entry receiver, and controls the low tire pressure warning lamp

as shown below. It also has a self-diagnosis function to detect a sys-

tem malfunction.

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-III. Refer to 

WT-32,

"Self-Diagnosis (Without CONSULT-III)"

. The tire pressure warning

check connector (1) is located behind the lower portion of the instru-

ment panel LH.
