Memory Operation

Each outside power mirror contains two motors. One motor moves the mirror up and down, and the other moves it left and right. The direction the motors turn depends on the supply voltage polarity sent to the motors. Mirror selection (LH or RH) and movement (up/down or left/right) is controlled by operating the power mirror switch. When the power mirror switch is operated, battery voltage is applied to the module select/position inputs. This causes the module to output voltage to the mirror motors, moving the mirror to the commanded position.

Mirror motor position sensors are used to remember the mirror positions. These sensors are potentiometers contained in the power mirror drive unit. As the mirror motors turn, the potentiometer resistance is varied. The mirror position is determined by the voltage level sent to the memory seat/mirror module. If the set memory button is pushed, and either memory select button (1 or 2) is pressed, the voltage level is stored to remember the mirror positions.
