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.
