Code B1850 Saturn Description

The Driver Seat Module (DSM) monitors the positions of most of the seat adjuster motors using hall effect type position sensors. The hall effect position sensors are supplied with battery positive reference and ground circuits from the DSM. The position sensor signal circuits are supplied battery positive voltage through a resistor then monitored within the DSM. During adjuster motor operation the hall effect position sensor provides a single pulse for every adjuster motor shaft rotation. The DSM counts the pulses from the position sensor signal circuits to determine the adjuster motor positions when storing or recalling memory seat position settings.
