What Does the B2145 Cadillac Code Mean?

The Memory Mirror Module (MMM) receives inputs from mirror position sensors during these functions: memory recall, memory seat and easy exit. Potentiometers in position sensors vary in resistance as motors move outside rearview mirror. MMM receives a variable voltage input depending on resistance of the potentiometer. During memory set, MMM records voltage across mirrors. During memory recall, MMM moves mirror motors until the voltage across each potentiometer matches recorded the voltage. During normal operation, mirror position sensors are checked against out-of-range limits. Outside rearview mirrors horizontal and vertical position sensor input voltage is 4.75 volts or more.
