Component Description: FCIM
WARNING: This page is about a different car, the 2017 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The FCIM contains the heated seat (or climate controlled seat) buttons.
If equipped with heated seats, the FCIM monitors the seat cushion temperature sensor and supplies heater current to the seat cushion and backrest heater mats until the desired setpoint temperature is reached. Once the setpoint temperature is reached, the FCIM cycles the heater circuits on/off as required to maintain the setpoint temperature. PMI is required when a new FCIM is installed.
