Hyundai Accent (HC) (2017 - 2022) Service Manual: TPMS Receiver

- Description 1.FunctionThe TPMS monitors the pressure and temperature of the tires and warns the driver of changes that could potentially influence driving conditions.The cluster warning lamp displays the messages generated from processing the data. The ECU processes the data received from the WE sensor, determines the conditions of the tire, and then sends any necessary warning signals to the driver through the CAN line or hard wire control line.
