Outline of the system 3.1 Description of the system operation This system is used for monitoring and indicating about information of air pressure and temperature in vehicle's tires. This transmitter sends to receiver the data that are information of air pressure and temperature in vehicle's tires. The data also include battery voltage and identity code of transmitter. The receiver judges if the data of air pressure and temperature from transmitter are not normal conditions. And then the receiver sends communication signals to a warning lamp through gateway ECU which is an intermediate ECU to divide signals . The warning lamp warns drivers. 3.2 Installation in vehicle. The transmitter is installed on tire wheel rim.(see Fig 3.2 Transmitter of installation) Fig 3.2 Transmitter of installation Tire Wheel rim TPMS Transmitter 6/10 4.
