POWER MIRROR CONTROL SYSTEM (w/ Memory) AUTO Power Retract Mirrors do not operate

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.

When the outer mirror control ECU assembly receives a door lock output signal from the main body ECU while the power retract mirror switch is in the AUTO position, the outer mirror control ECU assembly operates the retract motors built into the outer rear view mirrors to retract or return the mirrors.
