CAUTION / NOTICE / HINT

NOTICE:
·

When replacing the tire pressure warning ECU and receiver, read the transmitter IDs and number of the transmitters (4 or 5) stored in the old ECU using the GTS and write them down before removal.

·

It is necessary to perform initializationSuspension>TIRE PRESSURE MONITORING>TIRE PRESSURE WARNING SYSTEM (for Gasoline Model (for Type A))>INITIALIZATION after registrationSuspension>TIRE PRESSURE MONITORING>TIRE PRESSURE WARNING SYSTEM (for Gasoline Model (for Type A))>REGISTRATION of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.
