Circuit Description

The seat adjuster motors are equipped with potentiometer type position sensors used by the memory seat module to determine the seat position. The motor position sensors are supplied with 5-volt reference and ground circuits from the memory seat module. The position sensor signal circuits are referenced from ground within the memory seat module. The signal voltages monitored by the memory seat module range from 0.24-4.75 volts and are determined by the wiper locations on the resistors within the position sensors. The position sensor circuit voltage levels are used by the memory seat module to determine the position of the seat when storing or recalling memory position settings.
