Code C2514 Description

The Tire Pressure Monitoring System (TPMS). 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. If the air pressure of a tire drops below a certain value, the TPMS ECU makes the tread lamp turn on for letting a driver know. In a case of TPMS High specifications, it gets a driver to know which tire has a low pressure via a LED.
