Circuit Description

The driver seat adjuster motors are equipped with potentiometer type position sensors used by the driver seat module (DSM) to determine the seat position. The position sensors are supplied with 5-volt reference and ground circuits from the driver seat module. The position sensor signal circuits are referenced from ground within the DSM. The signal circuit voltage levels monitored by the DSM range from 0.39-4.58 volts and are determined by the wiper locations on the resistors within the motor position sensors. The position sensor circuit voltage levels are used by the DSM to determine the seat position when storing or recalling memory position settings.
