Test D: The Memory Mirror Is Inoperative

PINPOINT TEST D: THE MEMORY MIRROR IS INOPERATIVE

Normal Operation
Under normal operation, the exterior mirror control switch receives power from circuit SBP12 (GN/RD) and ground from circuit GD133 (BK). The exterior mirror control switch sends input to the driver seat module (DSM) for the LH exterior mirror by switching power and ground to circuits CPM16 (BU/BN), CPM17 (BU/GN) and CPM23 (GY), and for the RH exterior mirror by switching power and ground to circuits CPM20 (BN/WH), CPM21 (YE/VT) and CPM23 (GY). The DSM controls the vertical movement of the exterior mirror motors by supplying power and ground signals to the exterior mirror motor up/down circuits CPM26 (WH), CPM29 (GN), CPM31 (YE/GY) and CPM34 (WH/BN). The DSM controls the horizontal movement of the LH and RH exterior mirror motors by supplying power and ground signals to the exterior mirror motor left/right circuits CPM26 (WH), CPM28 (BU/BN), CPM31 (YE/GY) and CPM33 (WH/VT).

The DSM supplies the LH and RH exterior mirror feedback potentiometer reference voltage through circuit LPM30 (GY/VT) and ground through circuit RPM30 (YE). The DSM receives feedback from the LH exterior mirror feedback potentiometer through circuit (left/right) VPM35 (YE/BU) and circuit (up/down) VPM36 (BN/YE). The DSM receives feedback from the RH exterior mirror feedback potentiometer through circuit (left/right) VPM37 (BU/OG) and circuit (up/down) VPM38 (BN/GN).
