• If normal pressure values are displayed, the
IDs have been registered correctly.
• If the tire pressure values are not displayed
after several minutes, the IDs may be
incorrect or the system may have a
malfunction.

INITIALIZATION
1. DESCRIPTION OF INITIALIZATION
(a) Perform initialization in the following cases:
• Before delivery of a new vehicle.
• After replacement of the tire pressure warning
ECU*.
• After replacement of the tire pressure warning
valve and transmitter.
• Specified tire pressure changes depending on
the size or type of the tire.
*: Perform initialization after the transmitter ID
registration is completed (See page TW-20).
(b) Before initialization
(1) Set the air pressure of all tires to the specified
value.
Cold tire inflation pressure
NOTICE:
Perform the tire pressure adjustment after
the vehicle has sufficiently cooled down. If
the vehicle is not sufficiently cooled down,
increase the air pressure by 20 to 30 kPa (0.2
to 0.3 kgf/cm
2, 2.9 to 4.3 psi) above the
specified value.

2. INITIALIZATION PROCEDURE
(a) Make sure that the ignition switch is off.
(b) Connect the intelligent tester to the DLC3.
(c) Turn the ignition switch to the ON position.
(d) Select "TIREPRESS" by following the prompts
displayed on the intelligent tester.
(e) Press the tire pressure warning reset switch within
30 seconds after turning the ignition switch ON.
Keep the tire pressure warning reset switch pressed
for 3 seconds or more with the ignition switch ON.
(f) Check that the tire pressure warning light blinks 3
times (1 second ON, 1 second OFF).
HINT:
Initialization will be completed if signals are received
from all the wheels.
(g) Wait for 5 to 6 minutes with the ignition switch ON.
NOTICE:
• The initialization is normally completed
within 5 to 6 minutes.
• If the initialization has not been completed
successfully, DTC C2177/77 is set after the
vehicle is driven for 20 minutes or more.
• The initialization can be terminated by
connecting terminals TC and CG of the DLC3
connector.
3. CHECK THAT INITIALIZATION HAS BEEN
COMPLETED
(a) Confirm that the data of tire pressure of all tires are
displayed on the intelligent tester screen.

HINT:
*: It may take about 5 to 6 minutes until the values
are displayed. If the values are not displayed after
several minutes, perform troubleshooting according
to the inspection procedure for DTCs C2121/21 to
C2124/24 (See page TW-42).
NOTICE:
The following operations can be used instead of
above procedure:
1. Turn the ignition switch from OFF to ON.
2. Monitor the tire pressure values of all the
wheels using the intelligent tester.
3. If the tire pressure values cannot be
displayed on the intelligent tester screen, the
initialization has failed.
4. It takes about 5 to 6 minutes to display the
tire pressure data.

REMOVAL
1. REMOVE FRONT WHEEL
2. REMOVE REAR WHEEL
3. REMOVE TIRE PRESSURE WARNING VALVE AND
TRANSMITTER
(a) Remove the valve core and cap, and release the air
from the tire.
(b) After ensuring that a sufficient amount of air has
been released, remove the nut and washer that are
used to secure the tire pressure warning valve and
transmitter. Drop the tire pressure warning valve
and transmitter inside the tire.
HINT:
Keep the removed cap, valve core, nut, and washer.
(c) After dropping the tire pressure warning valve and
transmitter into the tire, disengage the bead using
the shoe of the tire remover.
NOTICE:
Be careful not to damage the tire pressure
warning valve and transmitter due to
interference between the valve and the tire bead.
(d) Remove the bead on the upper side in the usual
way.
(e) Take out the tire pressure warning valve and
transmitter from the tire and remove the bead on the
lower side in the usual way.
NOTICE:
If replacing the tire pressure warning valve and
transmitter, make sure that a new grommet and
a new washer are used.
INSTALLATION
1. INSTALL TIRE PRESSURE WARNING VALVE AND
TRANSMITTER
(a) Insert the tire pressure warning valve and
transmitter into the valve installation hole. Insert it
from the inside of the rim so that the printed surface
can be seen.
NOTICE:
• Check that there is no visible deformation,
damage, or other abnormalities on the tire
pressure warning valve and transmitter.
• Check that there is no foreign matter on the
inner grommet and around the rim hole.
• If the tire pressure warning valve and
transmitter is installed upside down, it may
be damaged or fail to transmit signals when
running at high speeds.
• If installing a new tire pressure warning valve
and transmitter, write down the ID number
before installation.
• It is necessary to register the ID in the ECU
after installation (See page TW-20).
