SYSTEM DESCRIPTION

This circuit is used for the signals from the outer mirror switch assembly.

The outer mirror switch assembly sends voltage signals to the main body ECU in accordance with how the switch is being operated (switch input signals). The main body ECU uses CAN communication to send this information to the outer mirror control ECU assembly, which then controls the adjustment of the mirror.
