TIRE PRESSURE MONITORING  TIRE PRESSURE WARNING SYSTEM(for Gasoline Model (for Type A))  Tire Pressure Warning Light Circuit  


DESCRIPTION

If the tire pressure warning ECU and receiver detects any problems, the tire pressure warning light blinks, and tire pressure monitoring is disabled at the same time. At this time, the ECU stores a DTC in memory.

The tire pressure warning ECU and receiver sends the tire pressure warning light illumination request signal to the main body ECU (multiplex network body ECU) via a direct line. The main body ECU (multiplex network body ECU) then sends the signal to the combination meter assembly via CAN communication.

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.
