Seat Heater Switch: Description and Operation
Operation
OPERATION
There are three positions that can be selected with each of the heated seat switches: Off, Low, or High. When the left side of the switch rocker is fully
depressed, the Low position is selected and the low position LED indicator illuminates. When the right side of the switch rocker is fully depressed, the
High position is selected and the high position LED indicator illuminates. When the switch rocker is moved to its neutral position (middle), Off is
selected and both LED indicators are extinguished.
Each switch provides separate resistor, hard wire inputs to its respective Heated Seat Module (HSM) to indicate the selected switch position. 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 40° C (105° F).
