POWER MIRROR CONTROL SYSTEM (w/ Retract Mirror) - Power Retractable Mirrors do not Operate with Power Retract Mirror Switch
SYSTEM DESCRIPTION
This circuit detects the conditions of the mirror retract switch.
The outer mirror switch sends information about the operating condition of the mirror retract switch (switch input signals) through the CAN communication line. Then the switch input signals are sent to the outer mirror control ECU.
