Heated Seat System Description
The heated seat control module controls the battery positive voltage
used to supply the seat heater elements. Ignition voltage is supplied to
the heated seat switch. When the heated seat switch is in the high or low
position ignition voltage is supplied through the on switch signal circuit
to the heated seat control module. Voltage to the high/low switch signal
circuit is reduced by the resistors within the heated seat switch, high or
low seat heater operation is determined by the voltage level to the heated
seat control module. The heated seat control module uses the resistance through
the heated seat thermistor to regulate the seat temperature. When the heated
seat reaches the maximum temperature for high or low operating modes the
battery positive voltage supply to the seat heater elements is removed. When
the seat cools the resistance value through the heated seat thermistor returns
to the limits set for high or low heated seat operation and the heated seat
control module provides the battery positive voltage supply to the heated
seat element supply circuit.
