B1591 Buick Description

The Left Mirror and the Right Mirror Vertical Position Sensors are Potentiometers. The Driver Door Module (DDM) and the Passenger Door Module (PFDM) determine the vertical position of the mirrors based on the signal voltage from these sensors. The code will be set when the signal voltage of the mirror vertical 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.
