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), Initiators and TPMS sensors. Among components of TPMS system, the initiator is only applied to TPMS High specifications. And its role is to control each TPMS sensor via the low frequency. This initiator enable a driver to see which tire has a low pressure.
The TPMS ECU sets this DTC if it receives an error signal from the LFI.
