Note:

w/ ID Switching Function:

(Main) is displayed on the DTC screen for the DTCs even when the 2nd set of tires is selected.

CAUTION / NOTICE / HINT

Note:

  • When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the GTS and write them down before removal.

  • It is necessary to perform initialization (Click here) after registration (Click here) of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.
