Code B3941 Saturn Description

The driver and passenger seat heaters are controlled by the Driver Seat Module (DSM). Power is supplied to the driver seat cushion and back heater elements through individual voltage supply circuits. Power is supplied to the passenger seat cushion and back heater elements through a common voltage supply circuit. All of the driver and passenger seat heater elements are grounded by the DSM through individual low side drive control circuits. The heater element control circuits are pulse width modulated to ground by the DSM in order to control the seat temperatures by regulating the current flow through the heater elements. The Diagnostic Trouble Code (DTC) sets when the DSM determines that one of the seat heater element voltage supply circuits is shorted to ground.
