The seat memory control module supplies a reference voltage to each signal circuit of the driver seat adjuster switch. When the power seat switches

are pressed, the appropriate signal circuit from the seat memory control module is pulled low through the switch contacts indicating the power seat

command. The seat memory control module then commands the driver seat to move in response to the switch signals.
