Pinpoint Test A: The Memory Mirror is Inoperative
Normal Operation
Under normal operation, the exterior mirror control switch receives voltage from Smart Junction Box (SJB) fuse 13 (5A) through circuit SBP13 (GY/RD) and ground from circuit GD133 (BK). The exterior mirror control switch uses circuits CPM16 (BN/BU), CPM17 (BU/GN), CPM20 (BN/WH), CPM21 (YE/VT) and CPM23 (GY) to send input signals to the Driver Door Module (DDM). The DDM (Driver Door Module) controls the LH exterior mirror motor movement by supplying the appropriate voltage and ground to circuits RPM05 (VT/GN), CPM28 (BU/BN) and CPM29 (GN). The DDM (Driver Door Module) communicates with the Driver Seat Module (DSM) through the Medium Speed Controller Area Network (MS-CAN) whenever the DDM (Driver Door Module) receives an input signal from the exterior mirror control switch for the RH mirror. The DSM (Driver Seat Module) controls the RH exterior mirror motor movement by supplying the appropriate voltage and ground to circuits CPM06 (GN/WH)/CPM31 (YE/GY), CPM33 (WH/VT) and CPM34 (WH/BN).
The memory mirror system uses feedback potentiometers, located in the LH and RH exterior mirror motors, in order to track the movement and position of the LH and RH exterior mirror motors. The DDM (Driver Door Module) supplies the LH exterior mirror feedback potentiometer reference voltage through circuit LPM30 (GY/VT) and ground through circuit RPM30 (YE). The DSM (Driver Seat Module) supplies the RH exterior mirror feedback potentiometer reference voltage through circuit LPM30 (GY/VT)/LPM12 (BU/GY) and ground through circuit RPM30 (YE)/RPM12 (VT/WH). The DDM (Driver Door Module) receives feedback from the LH exterior mirror feedback potentiometer through left/right circuit VPM35 (YE/BU) and up/down circuit VPM36 (BN/YE). The DSM (Driver Seat Module) receives feedback from the RH exterior mirror feedback potentiometer through left/right circuit VPM37 (BU/OG) and up/down circuit VPM38 (BN/GN).

- Fuse
- Wiring, terminals or connectors
