DESCRIPTION
The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressures. The measured values are transmitted to the tire pressure warning ECU and receiver in the vehicle as radio waves. The ECU compares the measured tire pressure values with the tire pressure threshold. When the measured tire pressure value is less than this threshold, the warning light in the combination meter assembly illuminates. The tire pressure warning ECU and receiver stores a DTC when the tire pressure warning valve and transmitter stops transmitting signals. The signals can be forcibly transmitted by releasing the tire pressure rapidly. The stored DTCs are cleared when signal transmission resumes.

(h) Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds.
(1) Check that each "ID Tire Inflation Pressure" value displayed on the Techstream has changed.
OK:
Each tire pressure value displayed on the Techstream will change to the value of the tire pressure.
NOTICE:
(2) After confirming that all of the tire pressure data displayed on the Techstream has changed, set the tire pressure to the appropriate specified values.
HINT:
If the tire pressure data displayed on the Techstream has not changed after rechecking, inspect for another problem.
