becomes 17 km/h (11 MPH).
>> Replace transmitter with new one if “DATA MONITOR ITEM” displays 64 psi or more. Refer to
WT-31, "
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
