B1586 CADILLAC MeaningThe Left Mirror and the Right Mirror Horizontal Position Sensors are Potentiometers. The Driver Door Module (DDM) and the Passenger Door Module (PFDM) determine the horizontal position of the mirrors based on the signal voltage from these sensors. The code will be set when the signal voltage of the mirror horizontal position sensor is above or below the range limits, within 10%, for 30 seconds in the requested position. The voltage range limits depend upon what the actual voltage of the 5 volt reference circuit is, and will vary from vehicle to vehicle and from module to module.
