The TPMS system is the shorten word of Tire Pressure Monitoring System. This system monitors the pressure of the tire and when it drops below a certain pressure, the TPMS ECU makes the warning lamp turn on for notifying the driver. This system consists of TPMS ECU(or TPMS Receiver), Initiators and TPMS sensors. The TPMS ECU gets signals such as Tire pressure, Tire temperature, Battery status and Sensor ID via RF(Radio Frequency) at a frequency.
If RF circuit has a problem, the TPMS ECU sets this DTC.
