The operating battery of TPMS module is supplied from the vehicle battery. Data such as Tire pressure, Tire Temperature, TPMS sensor battery status and TPMS sensor valve ID from TPMS sensors are transmitted to TPMS receiver in the form of RF signal. TPMS module accomplishes Tire Monitoring and Warning Logic with received data.
This DTC indicates that a commumication failure is occurred between micro controller and RF receiver in the TPMS ECU. In such a case no WE sensor data can be received/processed by the TPMS algorithm.
