CAUTION / NOTICE / HINT

Note:

  • When replacing the tire pressure warning ECU and receiver, first use the GTS to record all of the current IDs and registered tires with transmitters (4 or 5 tires) of the tire pressure warning valve and transmitter registered to the tire pressure warning ECU and receiver.

  • It is necessary to perform initialization after registrationClick hereof the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.

      Tip:

      • *: It may take a few minutes until the values are displayed.

      • The wheel position cannot be determined from ID1 through ID4 on the Data List.

      • When an "ID Tire Inflation Pressure" value has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270 degrees. Then rapidly release the tire pressure and recheck the value.
