TIRE AND WHEEL: TIRE PRESSURE WARNING VALVE AND TRANSMITTER: INSTALLATION

INSTALLATION

1. INSTALL TIRE PRESSURE WARNING VALVE AND TRANSMITTER
(a) Install a new grommet to the tire pressure warning valve and transmitter.
HINT: A new tire pressure warning valve and transmitter comes with a grommet. Therefore, it is not necessary to replace the grommet or install a new one.





(b) Insert the tire pressure warning valve and transmitter into the valve installation hole. Insert it from the inside of the rim so that the print surface can be seen.
- Replace the grommet even if it is not damaged when reusing the tire pressure warning valve and transmitter.
- Check that there is no oil, water or lubricant around the rim hole, tire pressure warning valve and transmitter, washer and nut. Failing to do so may result in improper installation.
- 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 Programming and Relearning.





(c) Install a new washer and a new nut on the tire pressure warning valve and transmitter from the rim side.
Torque: 4.0 Nm (41 kgf-cm, 35 in-lbf)
- No further tightening is required once the nut is tightened to the specified torque.
- Check that there is no foreign matter on the washer and nut.

(d) Set the wheel disc to a mounting machine and install the lower tire bead. At this time, position the main body of the tire pressure warning valve and transmitter in the shaded area shown in the illustration.




NOTICE:
- If the tire pressure warning valve and transmitter is positioned outside this area, it interferes with the tire bead, possibly causing damage to the tire pressure warning valve and transmitter.
- If the use of lubricant is required when installing the bead, do not apply the lubricant directly to the tire pressure warning valve and transmitter.

(e) Install the upper bead.
NOTE:
Make sure that the tire bead and tool do not interfere with the main body of the tire pressure warning valve and transmitter and that the valve and transmitter is not clamped by the bead.

(f) Install the valve core to the tire pressure warning valve and transmitter.
(g) Inflate the tire. If the valve nut is loose after inflating the tire, retighten the nut to the specified torque and then check for air leaks with soapy water.
Torque: 4.0 Nm (41 kgf-cm, 35 in-lbf)
NOTE:
Do not tighten the nut further after tightening it to the specified torque.

(h) Set the air pressure of the tires to the specified value.
(i) Install the cap to the tire pressure warning valve and transmitter.
2. INSTALL FRONT WHEEL
Torque: 103 Nm (1050 kgf-cm, 76 ft-lbf)
3. INSTALL REAR WHEEL
Torque: 103 Nm (1050 kgf-cm, 76 ft-lbf)
4. INSPECT TIRE
(a) Inspect the tire Component Tests and General Diagnostics.
5. REGISTRATION OF TRANSMITTER ID
(a) Register the transmitter ID Programming and Relearning.
6. CHECK TIRE PRESSURE AFTER REPAIRS
(a) After repairs, confirm that the actual tire pressures are displayed in the Data List Scan Tool Testing and Procedures.
