Transmitter Wake Up Operation
INFOID:0000000006246358
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.
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

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

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
Instruction 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
"Self-Diagnosis (Without CONSULT-III)"
. The tire pressure warning
check connector (1) is located behind the lower portion of the instru-
ment panel LH.
