DESCRIPTION
The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the air pressure of the tires. The measured
values are transmitted to the tire pressure warning antenna and receiver on the body as radio waves and then sent to the tire pressure warning ECU.
The ECU compares the measured air pressure values with the air pressure threshold. When the measured air pressure value is less than this
threshold, the warning light in the combination meter comes on. The tire pressure warning ECU stores a DTC when the tire pressure warning valve
and transmitter stops transmitting signals. At this time, forcibly transmit the signals by releasing the tire pressure rapidly. The stored DTC is cleared
when the signal transmission is resumed.
HINT
It is necessary to perform the procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because
it cannot be identified by the output DTC.
INSPECTION PROCEDURE
NOTICE:
* When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using the Techstream and note
them down before removal.
* It is necessary to perform the initialization See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring
System/Testing and Inspection/Programming and Relearning/Initialization (from 12/2010) after the registration See:
Instrument Panel, Gauges and Warning Indicators/Tire Monitoring System/Testing and Inspection/Programming and
Relearning/Registration (from 12/2010) of the transmitter IDs into the tire pressure warning ECU if the ECU and/or one of
the valve and transmitters have been replaced.
PROCEDURE
1. PERFORM FORCED TRANSMISSION OF TRANSMITTER ID OF ALL WHEELS
(a) Set the air pressure of all the wheels to the specified value See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring
System/Service Precautions/Precaution (from 12/2010).
(b) Make sure that the ignition switch is off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch on (IG).
(e) Turn the Techstream on.
(f) Confirm that the data of tire pressure of all the tires (including the spare tire) are displayed on the Techstream display. Enter the
following menus: Chassis / Tire Pressure Monitor / Data List.
