Normal Operation
The exterior mirror control switch uses circuit 540 (RD) to control the LH exterior mirror left/right movement, circuit 541 (DB) to control the LH exterior mirror up/down movement, and circuit 542 (YE) as a common circuit to control the LH exterior mirror up/down and left right movement. The exterior mirror control switch uses circuit 545 (WH) to control the RH exterior mirror left/right movement, circuit 544 (VT) to control the RH exterior mirror up/down movement, and circuit 542 (YE) as a common circuit to control the RH exterior mirror up/down and left right movement. Each circuit is a switched voltage/ground circuit based upon the exterior mirror control switch position.
