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

INSTALLATION

1. INSTALL TIRE PRESSURE WARNING VALVE AND TRANSMITTER





(a) Insert the tire pressure warning valve into the valve installation hole 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 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 in the reverse direction, it may be damaged or fail to transmit signals when running at a high speed.
- If installing a new tire pressure warning valve and transmitter, write down the transmitter ID before installation.
- The transmitter ID registration must be performed for all tire pressure warning valve and transmitters, regardless of the number of tire pressure warning valve and transmitters replaced. If all of the tire pressure warning valve and transmitters do not need to be replaced, check the DATA LIST and write down the transmitter IDs of the tire pressure warning valve and transmitters that do not need to be replaced before performing the transmitter ID registration Registration.
- It is necessary to perform initialization Initialization after registration Registration of the transmitter IDs into the tire pressure warning ECU after the tire pressure warning valve and transmitter has been replaced.

(b) If reusing the tire pressure warning valve and transmitter:
Install a new grommet.
HINT: A new tire pressure warning valve and transmitter is supplied with a grommet.





(c) Install the washer on the tire pressure warning valve from the rim side and tighten the nut.
Torque: 4.0 Nm (41 kgf-cm, 35 in-lbf)
NOTICE:
- No further tightening is required once the nut is tightened with the specified torque.
- Check that there is no foreign matter on the washer and nut.
- Check that there is no oil, water or lubricant around the rim hole, tire pressure warning valve, washer and nut. Failing to do so may result in improper installation.





(d) Set the wheel disc to a mounting machine and install the lower tire bead. Position the main body of the tire pressure warning valve and transmitter in the shaded area as shown in the illustration.
NOTICE:
- If the tire pressure warning valve and transmitter is positioned outside this area, the tire bead will interfere with the tire pressure warning valve and transmitter, and may cause damage to it.
- 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 tire pressure warning valve and transmitter is not clamped by the bead.

(f) Inflate 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: No further tightening is required once the nut is tightened with the specified torque.

2. INSTALL WHEEL
for Aluminum Wheel - Torque: 131 Nm (1336 kgf-cm, 97 ft-lbf)
for Steel Wheel - Torque: 209 Nm (2131 kgf-cm, 154 ft-lbf)
3. INSPECT TIRE
(a) Inspect the tire Component Tests and General Diagnostics.
4. REGISTRATION OF TRANSMITTER ID
(a) Register the transmitter ID Registration.
5. PERFORM INITIALIZATION
(a) Perform initialization Initialization.
NOTE: Be sure to inflate all tires to the proper inflation pressure before initialization.

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.
