Without Memory
The inside rearview mirror can be manually adjusted by tilting the mirror.
With Memory
The inside rearview mirror contains two reversible DC motors and two position sensors. One motor adjusts the mirror to the UP/DOWN (vertical) position and the other motor adjusts the mirror to LEFT/RIGHT (horizontal) position. The driver memory seat module controls the mirror direction by changing the polarity of the voltage applied to the motors.
The driver memory seat module supplies a 5 volt reference and reference ground to the position sensors. The driver memory seat module monitors the signal circuits of the position sensors to determine the position of the mirrors. The driver memory seat module stores the position of the mirrors when a memory feature is requested.
