Component Description

WARNING: This page is about a different car, the 2015 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Heated Seat Switch

The heated seat switch is a momentary contact switch that, when pressed, completes a circuit to chassis ground.

Heated Seat Module

When commanded by the heated seat switch, the heated seat module monitors the appropriate seat cushion temperature sensor(s) 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 heated seat module cycles the heater circuits on/off as required to maintain the setpoint temperature. The heated seat module does not report Diagnostic Trouble Codes (DTCs) and does not communicate on any network. If the heated seat module detects a fault, the affected seat system is disabled.

Seat Heater Mat

Each seat cushion heater mat is equipped with a temperature sensor (thermistor) which provides feedback to the heated seat module. The heater mats are serviced by installing a new backrest or cushion foam. The cushion and backrest heater mats are connected in series.
