Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Heated Seat Operation
The driver and passenger heated seat buttons are selected from the FCIM and FDIM (touchscreen). The heated seat system functions independently of the vehicle's climate control system. Each time the heated seat button is pressed, the system decreases one setting (the sequence is high, med, low, off, high, etc.).
When activated, the FCIM supplies voltage to the selected seat heater circuit. Each seat cushion heater mat and backrest heater mat is connected in a series circuit to the FCIM and powered by the output circuit for that seat. The FCIM monitors inputs from a temperature sensor located in each seat cushion heater mat, and maintains seat temperature by cycling the heater circuits on/off. The heated seat remains ON until the heated seat switch button is pressed to cycle the FCIM OFF or the ignition is set to OFF.
If a fault is detected by the FCIM, the module stops supplying voltage to that individual left or right seat that the fault was detected on until the ignition is turned OFF and then ON.
