With Memory

Each outside rear view mirror contains two motors. One motor moves the mirror up and down. The other motor moves the mirror left and right. The direction the motors turn depends on the supply voltage polarity sent to the motors. Mirror selection (left or right) and movement (up/down or left/right) is controlled by operating the mirror switch. When the 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.

The mirror motor position sensors are used in order 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. The voltage level is stored in order to remember the mirror positions under the following conditions:
^ The set memory button is pushed.
^ Either memory select button (1 or 2) is pressed.
