Memory Mirrors (W/A45)

The vehicle may be equipped with the "personalization package" containing memory seats and memory mirrors. The memory mirrors are also controlled by the LH front power window switch, driver door module, and the passenger door module. The mirrors are equipped with potentiometer circuits that provide constant information to the passenger door module and the driver door module on the location of the mirrors on their horizontal and vertical axis. This information is in the form of feedback voltage received from their potentiometers.

When a mirror location is programmed into the personalization package, the driver door module and passenger door module store the location information and assign it to the personalization code. When that personalization code is received the modules check the current position of the mirrors and move them to the correct position. The modules move the mirrors until the feedback voltage from the mirrors match the voltage levels stored as correct for that personalization code.
