DISPOSAL
HINT:
The tire pressure monitor valve sub±assy is powered by a lithi-
um battery. When disposing of the tire pressure monitor valve
sub±assy, remove the battery and dispose of it correctly.
DISPOSE OF TIRE PRESSURE MONITOR VALVE
(a) Insert the tip of a screwdriver into the clearance and pry
off the cover. Remove the back cover.
(b) The battery and base board covered with silicone resin
are exposed. While taking out the battery, cut off the 2 ter-
minals which connect the battery and base board.

REPLACEMENT
1. REMOVE FRONT TIRE
2. REMOVE REAR TIRE
3. REMOVE TIRE PRESSURE MONITOR VALVE
(a) Remove the valve core and cap, and release air from the
tire.
(b) After ensuring that air is sufficiently released, remove the
nut and washer that are used to fix the tire pressure moni-
tor valve sub±assy and drop the sensor inside the tire.
HINT:
Keep the removed cap, valve core, nut and washer.
(c) After dropping the tire pressure monitor valve sub±assy
into the tire, disengage the bead using the shoe of the tire
remover.
NOTICE:
Be careful not to damage the tire pressure monitor valve
because of interference between the sensor and tire bead.
(d) Remove the bead on the upper side.
(e) Take out the sensor from the tire and remove the bead on
the lower side.
(f) Remove the inner grommet from the tire pressure monitor
valve sub±assy.
HINT:
Check that there are no cracks or damage to the grommet. If
any damage is found, replace the grommet together with the
washer and nut.
4. INSTALL TIRE PRESSURE MONITOR VALVE
(a) Insert the tire pressure monitor valve into the valve instal-
lation hole. Insert from the inside of the rim so that the print
surface can be seen.
NOTICE:
Check that there is no visible deformation, damage or
other abnormalities on the transmitter.
Check that there is no foreign matter on the inner
grommet and around the rim hole.

If installed in the reverse direction, the tire pressure
monitor valve may be damaged or fail to transmit sig-
nals when running at high speed.
If installing a new tire pressure monitor valve, write
down the ID number before installation.
It is necessary to registor an ID in the ECU after instal-
lation (See page DI±805).
(b) Install the washer on the tire pressure monitor valve from
the rim side and tighten with a nut.
Torque: 4.0 NVm (41 kgfVcm, 35 in.Vlbf)
NOTICE:
Check that there is no foreign matter on the washer
and nut.
If the tire pressure monitor valve is removed when the
tire is removed for replacement, check that there is no
damage or cuts, and no foreign matter such as mud,
dirt or sand attached to the grommet. Replace the
grommet with a new one if any of the defects men-
tioned above are found.
Check that there is no oil, water or lubricant around
the rim hole, tire pressure monitor valve, washer and
nut. Failing to do so may result in improper installa-
tion.
(c) After the tire is inflated, the valve nut may be loose. Re-
tighten the nut to the specified torque and then check for
air leaks with soapy water.
Torque: 4.0 NVm (41 kgfVcm, 35 in.Vlbf)
(d) Set the wheel disc to the mounting machine and install the
lower tire bead. Position the main body of the sensor as
in the shaded area shown in the illustration.
NOTICE:
If the sensor is positioned outside this area, it generates in-
terference with the tire bead, causing possible damage to
the sensor.
(e) Install the upper bead.
NOTICE:
Make sure that the tire bead and tool do not interfere with
the main body of the sensor and that the sensor is not
clamped by the bead.
