Memory Operation

Operation of the Memory Mirrors is similar to that of the Memory Seats. Each 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 Mirror Control Switch Assembly. When the switch assembly is operated, battery voltage is applied to the module's 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 mirror's 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/Memory Mirror Control 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.
