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 DDSA, DDM and PFDM. The mirrors are equipped with potentiometer circuits that provide constant information to the DDM and PFDM on the location of the mirrors on their horizontal and vertical axis. This information is in the form of feedback voltage received from their respective potentiometers.

When a mirror location is programmed into the personalization package, the DDM and PFDM 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.
