Test F: The Memory Mirror Is Inoperative

PINPOINT TEST F: THE MEMORY MIRROR IS INOPERATIVE

Normal Operation
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 (BN/BU), 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 will then supply the appropriate power and ground signals for the LH exterior mirror motor up/down circuits CPM26 (WH), CPM29 (GN) and left/right circuits CPM26 (WH), CPM28 (BU/BN), or the RH exterior mirror motor up/down circuits CPM31 (YE/GY), CPM34 (WH/BN) and left/right circuits CPM31 (YE/GY), 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 (up/down) VPM35 (YE/BU) and circuit (left/right) VPM36 (BN/YE). The DSM receives feedback from the RH exterior mirror feedback potentiometer through circuit (up/down) VPM37 (BU/OG) and circuit (left/right) VPM38 (BN/GN).
