C1346 KIA Description

The Tire Pressure Monitoring System (TPMS) 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 Initiator controls each TPMS sensor via the low frequency. This initiator enables a driver to see which tire has a low pressure.
