<p>A seat heater system and method are disclosed. The seat heater system includes a control unit with a switch for transmitting an activation signal and an indicator for receiving an indicator signal. The seat heater system includes a heater unit for receiving the activation signal and transmitting the indicator signal. A transmission line defines a single line of communication between the control unit and the heater unit. The single transmission line operates according to different first and second predetermined voltages. The indicator signal is transmittable when the single transmission line operates according to the first predetermined voltage. The activation signal is transmittable when the single transmission line operates according to the second predetermined voltage. The heater unit selectively toggles operation of the single transmission line between the first and second predetermined voltages such that the heater unit maintains communication with the switch and the indicator through the single transmission line.</p> |
