Tire"
Are there any tires with pressure of 64 psi or more?
YES >> Adjust tire pressure to specified value.
NO >> GO TO 2.
2. VEHICLE DRIVING
1. Carry out ID registration of all transmitters.
2. Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping. Check all tire pressures with CONSULT-II “DATA MONITOR ” within 15 minutes after vehicle speed
becomes 17 km/h (11 MPH).
>> Replace transmitter with new one if “DATA MONITOR” displays 64 psi or more. Refer to WT-36,
"Transmitter (Pressure Sensor)" . Then GO TO 3.
3. ID REGISTRATION AND VEHICLE DRIVING
1. Carry out ID registration of all transmitters.
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for 10 minutes. Then check all tire pressures with CONSULT-II “DATA MONITOR” within 5 minutes.

REMOVAL AND INSTALLATIONPFP:00000
Transmitter (Pressure Sensor)EES001IN
REMOVAL
1. Deflate tire. Unscrew transmitter retaining nut and allow transmitter to fall into tire.
2. Gently bounce tire so that transmitter falls to bottom of tire.
Place wheel and tire assembly on tire changing machine and
break both tire beads. Ensure that the transmitter remains at the
bottom of the tire while breaking the bead.
3. Turn tire so that valve hole is at bottom, and gently bounce the tire to ensure transmitter is near valve hole. Carefully lift tire onto
turntable and position valve hole (and transmitter) 270 degrees
from mounting/dismounting head.
4. Lubricate tire well, and remove top side of tire. Reach inside the tire and remove the transmitter.
5. Remove the second side of the tire as normal.
INSTALLATION
1. Place first side of tire onto rim.
2. Mount transmitter on rim and tighten nut to specification.
