This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.
New replacement transmitters are provided asleep and must first be woken up using Transmitter Acti-
vation Tool J-45295 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-50, "Tire"

System Description

INFOID:0000000005275719

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.

TRANSMITTER

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.

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 CONSULT-III. Refer to 

WT-33,

"Self-Diagnosis (Without CONSULT-III)"

. The tire pressure warning

check connector (1) is located behind the lower portion of the instru-
ment panel LH.
