Normal Operation
Under normal operation, the exterior mirror control switch receives power from circuit 956 (OG/LG) and ground from circuit 1205 (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 942 (RD/OG), 940 (DB/OG) and 945 (YE/BK) and for the RH exterior mirror by switching power and ground to circuits 944 (DG/OG), 943 (PK/OG) and 945 (YE/BK). The DSM will then send the appropriate power and ground for the LH exterior mirror motor UP/DOWN circuits 1486 (YE/LB), 1487 (DB) and LEFT/RIGHT circuits 1485 (RD) and 1484 (YE/RD) or the RH exterior mirror motor UP/DOWN circuits 1482 (PK), 1483 (WH/PK) and LEFT/RIGHT circuits 1480 (WH/LG) and 1481 (DG).
- DTC B1667 will set if the DSM senses low voltage at circuit 1486 (YE/LB) or circuit 1487 (DB).
- DTC B1668 will set if the DSM senses low voltage at circuit 1485 (RD) or circuit 1484 (YE/RD).
- DTC B1669 will set if the DSM senses low voltage at circuit 1482 (PK) or circuit 1483 (WH/PK).
- DTC B2312 will set if the DSM senses low voltage at circuit 954 (DG/WH).
- DTC B2314 will set if the DSM senses circuit 954 (DG/WH) is shorted to battery voltage.
- DTC B2316 will set if the DSM senses low voltage at circuit 957 (VT/WH).
- DTC B2318 will set if the DSM senses circuit 957 (VT/WH) is shorted to battery voltage.
- DTC B2320 will set if the DSM senses low voltage at circuit 949 (RD/WH).
- DTC B2322 will set if the DSM senses circuit 949 (RD/WH) is shorted to battery voltage.
- DTC B2324 will set if the DSM senses low voltage at circuit 951 (DB/WH).
- DTC B2326 will set if the DSM senses circuit 951 (DB/WH) is shorted to battery voltage.

Possible Causes
- An open, short to voltage or short to ground in circuits: 943 (PK/OG), 942 (RD/OG), 945 (YE/BK), 944 (DG/OG), 940 (DB/OG), 1480 (WH/LG), 1481 (DG), 1482 (PK), 1483 (WH/PK), 1484 (YE/RD), 1485 (RD), 1486 (YE/LB) or 1487 (DB)
- Open in circuit 956 (OG/LG)
- Open in circuit 1205 (BK)
- Inoperative DSM
- Inoperative exterior mirror control switch
- Inoperative exterior mirror
