Code B2287 Cadillac Description

The Driver Door Module (DDM) and the Passenger Door Module (PDM) receive vertical and horizontal position signals from the mirrors. These signals are used by the DDM and PDM for memory recall functions to determine the vertical and horizontal positions of the mirrors. The DDM and PDM command the mirror memory settings based on the voltage level they receive back from the position sensors. Each door module provides a 5 volt supply, a signal, and a ground circuit to the sensors. The sensors are variable resistors that the DDM and PDM monitor the voltage level across. When a memory setting is recalled, the DDM and PDM command the mirror motors in the appropriate direction until the position sensors are within the voltage range stored in memory. The DDM and PDM monitor the mirror position sensors 5 volt supply circuits to determine if the voltage level received is out of range. If the DDM or PDM detects a voltage level out of range for greater than 2 seconds, a Diagnostic Trouble Code (DTC) is set.
