Ford Ecosport: Tire Pressure Monitoring System (TPMS) / Description and Operation - Tire Pressure Monitoring System (TPMS) - Overview
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.
