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 ECU makes the warning lamp turn on for notifying the driver. This system consists of TPMS ECU(or TPMS Receiver) 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 it is detected as an error in the TPMS ECU, this DTC is set.
