Code B2312 Ford Description

Under normal operation, the exterior mirror control switch receives power and ground from the circuit. The exterior mirror control switch uses circuits to send input signals to the Driver Door Module (DDM). The DDM controls the Left (LH) exterior mirror motor movement by supplying the appropriate power and ground to circuits. The DDM communicates with the Driver Seat Module (DSM) through the Medium-Speed Controller Area Network (MS-CAN) whenever the DDM receives an input signal from the exterior mirror control switch for the Right (RH) mirror. The DSM controls the RH exterior mirror motor movement by supplying the appropriate power and ground.
The memory mirror system uses feedback potentiometers, located in the LH and RH exterior mirrors, in order to track the movement of the LH and RH exterior mirror motors. The DDM supplies the LH and RH exterior mirror feedback potentiometer reference voltage and ground through circuits. The DDM receives feedback from the LH and RH exterior mirror feedback potentiometer through left/right and up/down circuits.
