B1825 SATURN Description
The seat recline motor is equipped with a potentiometer type position sensor used by the Driver Seat Module (DSM) to determine the position of the seat back. The motor position sensor is supplied with 5-volt reference and ground circuits from the DSM. The position sensor signal circuit is referenced from ground within the DSM. The signal voltage monitored by the DSM ranges from 0.39-4.58 volts and is determined by the wiper location on the resistor within the motor position sensor. The position sensor circuit voltage level is used by the DSM to determine the position of the seat back when storing or recalling memory position settings.
