Front Seats

OPERATION

There are two momentary positions that can be selected with the heated seat switches, low and high. When the switch closest to the driver/passenger is depressed, the low position is selected and the "LO" position LED indicator illuminates. When the switch farthest from the driver/passenger is depressed, the high position is selected and the "HI" position LED indicator illuminates. If the switch is depressed a second time in the same direction, off is selected and both LED indicators are extinguished.

Both heated seat switch assemblies provide separate resistive multiplexed inputs to the appropriate door module. The Door Module then sends a PCI Data Bus message to the Memory Heated Seat Adjustable Pedal Module (MHSAPM) to indicate the selected switch position. The module responds to the heated seat switch messages by controlling the 12v output to the front seat heating elements. The low heat position set point is about 35° C (97° F), and the high heat position set point is about 40° C (105° F).
