Tire Pressure Monitoring System (TPMS) - Overview


The BCM monitors the tire pressure in the 4 road tires with tire pressure sensors that communicate the tire pressure via radio signals to the BCM . The tire pressure sensors are battery operated and mounted to the valve stems. All of the controlling software for the TPMS is contained in the BCM . The IPC illuminates the TPMS warning indicator and the message center displays a message when a fault is present or when the tire pressure falls below the low pressure limit.
