WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.

The tire pressure warning valve and transmitter installed in each tire and wheel assembly measures the tire pressure The measured values are transmitted as radio waves to the tire pressure warning antenna on the body and then set to the tire pressure warning ECU and receiver. 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 and a warning message is displayed on the multi-information display The tire pressure warning ECU stores a DTC when the tire pressure warning valve and transmitter stops transmitting signals DTC check the tire pressure warning valve and transmitter stops transmitting signals If this occurs, forcibly transmit signals by rapidly releasing the tire pressure. The stored DTC is cleared when the signal transmission is resumed.
