Passenger Heated Seat Switch: Operation
There are three modes that can be selected with each of the heated seat switches: Off, Low, and High. When the front of the switch rocker is depressed, the High mode is selected and the high mode LED indicator illuminates. Depressing the front of the switch rocker a second time will turn the heated seat to Off. When the rear of the switch rocker is depressed, the Low mode is selected and the low mode LED indicator illuminates. Depressing the rear of the switch rocker a second time will also turn the heated seat to Off. In addition, the heated seats will automatically return to the Off mode anytime the vehicle ignition switch is turned Off.
Both switches provide separate resistor multiplexed hard wire inputs to the Heated Seat Module to indicate the selected mode. The Heated Seat Module responds to the heated seat switch status messages by controlling the output to the seat heater elements of the selected seat. The Low heat position set point is about 36° C (97° F), and the High heat position set point is about 41° C (105° F).
