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:0000000007357035

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.
2. Select ID REGIST under BCM.

< BASIC INSPECTION >

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.
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

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.
