The TPMS is the acronym for Tire Pressure Monitoring System. This system monitors the pressure of the tire and when it drops below a certain pressure, the TPMS Module(TPMS ECU) makes the warning lamp turn on for notifying the driver. This system consists of TPMS Module and TPMS sensors. The TPMS Module gets signals such as Tire pressure, Tire temperature, Battery status and Sensor ID via RF(Radio Frequency) at a frequency.
