Heated Seats - Rear (Taurus X)

Rear heated seats are controlled by a heated seat module and heated seat switches located in the front console. When a heated seat switch is pressed and ignition ON, a momentary ground signal is sent to the heated seat module. The heated seat module then supplies voltage to the heater circuit. The seat cushion and backrest heater mats are wired in series. The heated seat module monitors inputs from a temperature sensor, located in each seat's cushion heater mat and maintains seat temperature by cycling the heater output as necessary to maintain the setpoint temperature. The heated seat module also outputs voltage to the appropriate indicator circuit in the heated seat switch indicating the system is on. The heated seat module remains on until the heated seat switch is pressed a second time in that mode or the ignition switch is cycled OFF.

If a fault is detected by the heated seat module, the module will stop supplying power to that individual left or right seat as well as the switch indicator on which that fault was detected. The faults detected will be: a heater feed circuit short to battery, ground or open; sensor circuit short to battery or open; heated seat switch stuck closed to ground or heated seat switch low and high inputs shorted together. To reset the module, cycle the ignition switch OFF and then ON. After the heated seat module has been reset, the module will return to an off state. The heated seat module does not report DTCs and does not communicate on any communication network.
