POWER MIRROR CONTROL SYSTEM (w/ Memory) Power Retractable Mirrors do not Operate with Power Retract Mirror Switch

SYSTEM DESCRIPTION

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

The outer mirror retractable switch sends a voltage signal to the main body ECU in accordance with switch operation (switch input signal). The main body ECU uses CAN communication to send this information to the outer mirror control ECU assembly, which then controls the mirrors.
