INFOID:0000000007357034
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

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.

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 Diagram

System Description
INFOID:0000000007357037
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.
