Component Description: FCIM
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The FCIM contains the heated seat (or heated/ventilated seat) buttons.
If equipped with heated seats, when the heated seats are activated, 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.
