Normal Operation
The exterior mirror control switch receives power from circuit 29-AD12 (OG/YE) and ground from circuit 31-AD12 (BK/YE). The exterior mirror control switch sends input to the driver door module (DDM) for the LH exterior mirror by switching power and ground to circuits 32-AD32 (WH/RD), 34-AD31 (BU/WH) and 33-AD12 (YE) and for the RH exterior mirror by switching power and ground to circuits 32-AD30 (WH/BK), 34-AD29 (BU/OG) and 33-AD12 (YE). The DDM then sends the appropriate power and ground for the LH exterior mirror motor up/down circuits 34-AD8 (BU/WH), 35-AD8 (VT) and left/right circuits 32-AD7 (WH/RD) and 33-AD7 (YE/RD). The DDM sends a message to the front electronic module (FEM) over the SCP communication link for the FEM to send the appropriate power and ground for the RH exterior mirror motor up/down circuits 34-AD11 (BU/OG), 35-AD11 (VT/WH) and left/right circuits 32-AD10 (WH/BK), 33-AD10 (YE/BK).
