Circuit/System Description
The driver door module (DDM) and passenger door module (PDM) each provide motor control output functions for their respective mirrors. These output controls allow each door module to command their respective power mirrors in horizontal and vertical positions. When the door modules detect an active mirror command they will command the respective mirror motor in the appropriate direction. Each door module controls their respective mirror motors by applying a ground or voltage to the control circuit, depending on the desired mirror position.
